Summary of geological survey work

Three comments on the summary of geological exploration work

Geological survey work should be serious and careful, often make summary reports, and mistakes occur at the same time. The following is a summary essay of geological survey work compiled by me, welcome to read!

Summary of Geological Survey: The geotechnical engineering survey of the new campus of Jining No.1 Middle School is the first project I participated in completely. The geotechnical investigation task of this project is 4970 m /2 16 hole, and 8 drilling rigs are used for construction. The field work was carried out on1October 30th from 65,438+05 to 65,438+00. In this short time,

1, hole

This project has 2 16 holes. The project is characterized by tight construction period and many holes. When drilling, we should first be familiar with the drawings, understand and master the general position of each hole on the drawings, and remember the surrounding environment characteristics of each hole when drilling, so as to lay a good foundation for the next drilling work.

2, drilling rig layout

Because of the wide site, many holes, tight tasks and many drilling rigs, the drilling direction of drilling rigs should be selected according to the principle of "reducing the moving distance of drilling rigs and drilling more holes", which can not only save labor, but also speed up the project progress.

Step 3 drill

There are eight rigs in this project, but only two catalogers. In this case, it is impossible to catalog each rig at the same time, which requires the rig captain to write down the number of meters on the core after a return. However, because drilling rigs are paid by meters, almost all captains will write a few meters more on the meters without supervision. This has brought a lot of unnecessary trouble to catalogers. In this case, the cataloger should not only identify the actual meters of soil samples by himself, but also strengthen the education of the captain. For example, a 25-meter borehole can make them hit 2 1-22 meters, giving them a certain amount of work, but ensuring the accuracy of each returned meter.

4. Identify soil samples

Due to more drillers and fewer logging personnel, it is impossible to ensure that all drilling holes can be recorded in time. Some soil samples lose water for a long time during logging, so it is difficult to distinguish silt from silty clay. At this time, it is necessary to step on the soil sample with your feet and observe the overall toughness of the soil sample. Generally speaking, the overall toughness of silty clay is higher than that of silty clay.

5. Safety

This is a commonplace topic. When drilling, we must make sure that everyone wears a helmet. It is particularly important to note that the final stage of each project is the stage of sudden accidents. We must remind the drillers not to worry. Safety is the most important thing.

Postscript: Every driller is an ordinary farmer. In order to make a living, they have to dig wells hundreds of kilometers away from home. Life here is hard, which ordinary people can't imagine. They had to live in tents built in the wild. The so-called bed is the board, and their daily job is to deal with the soil. Whether it is hot summer or cold winter, they all need to work in the field, and every penny of them is their hard-earned money. Drilling is a hard job, and drilling is a dangerous job. Salute them, great working people!

Summary of Geological Exploration 2 Xiamen-Chengdu Expressway Guizhou Shuikou (Guangxi-Guizhou boundary) to Duyun Highway is an integral part of the "79 18" national expressway network 16 cross-Xiamen-Chengdu Expressway (hereinafter referred to as Xiamen-Chengdu Expressway), and it is also an important part of the "three verticals, three horizontals, eight links and eight branches" skeleton highway network planned by Guizhou Province.

The total length of the route of this project is 58.772km, and the length of bridge and tunnel accounts for about 60.5% of the total length of the route. Total length of bridge 17494.65m /40 (full width, the same below), in which: 635 extra large bridges1.48m/6 large and medium-sized bridges143.17m/34 large and medium-sized bridges; Total length of tunnel 18089.65m/14 (double tunnels, the same below), in which extra-long tunnel 14625.8m/6, medium-short tunnel 3276.35m /7 and multi-arch tunnel 187.5m/65438.

This project has the characteristics of great technical difficulty, heavy task, complex topography and geology, tight construction period, high cost and great interference from the owner.

On March 1 day of xx every year, the designers of our institute enter the construction site to carry out the survey and design work in an all-round way; On March 5th, our hospital received a notice from the owner that the route corridor was adjusted, and the southern line scheme was changed to the northern line scheme, which affected our hospital by 48km (82%). The project team overcame unfavorable factors such as incomplete topographic map and insufficient surveying and mapping scope, and worked overtime in a short time to overcome difficulties. Complete the preliminary design field work in mid-May, and complete the preliminary design documents by the end of June. During this period, according to the requirements of the owner, the scheme research, terminal route scheme research and preliminary design of Sandu Interchange will be supplemented; In July, optimize the design scheme and budget estimate; From September 4th to 5th, the preliminary design was pre-examined in the province, and the preliminary design documents were revised according to the review opinions. In June 5438 +XX 10, it passed the examination of the Ministry of Communications.

On August 10, the pay-off personnel entered the site, and on September 6, all professional designers entered the construction site, and the field work of construction drawings was in full swing. From September 10 in xx to October 1013 in xx, the project team completed the construction drawing, and at the same time, together with Guizhou Expressway Development Corporation, consulting units and overall units, optimized the preliminary design scheme and construction drawing scheme and added Sandu Interchange; According to the owner's requirements, our institute made a comprehensive revision to the preliminary design documents on June 5438+065438+ 10.

Xx year1Oct. 30 10, and the construction drawing survey of this contract section ended. Xx year 1 1.2-5, the general office of our hospital went to the site for on-the-spot acceptance. Xx year 65438+February 19 ~ 22, Guizhou Provincial Communications Department and Guizhou Provincial Expressway Development Corporation conducted pre-acceptance of the construction drawing of this project. From March 29th to April 1 day, XX year, Guizhou Provincial Communications Department and Guizhou Provincial Expressway Development Corporation conducted on-the-spot acceptance of the construction drawing of this project, and completed the construction drawing design on April 30th.

The fifth contract section of Xiamen-Chengdu Expressway is a project outside the province, with great difficulty, large scale, great technical difficulty, long distance, high cost and great changes. Our hospital completed the design of this project in 65,438+05 months. Now, according to the characteristics of the project and the completion process, we have summarized the following experiences:

First, strengthening the overall design and coordination is conducive to the progress and quality of survey and design.

The project is undertaken by four civil engineering units and two traffic engineering units. As an overall unit, Guizhou Provincial Academy has done a lot of work in the progress of the project. According to the characteristics of the project, detailed overall design principles are formulated. In order to unify the design standards for the whole line and vigorously promote the standardization work, the general unit presided over and completed a lot of basic work. With the joint efforts of four design units, the general drainage plan of bridges, tunnels, subgrade and pavement has been compiled. Compiling and perfecting the master plan is helpful to strengthen technical exchange, absorb the advantages of brother units and improve their own design level. The progress of the general plan of the project is inconsistent, and the tasks undertaken by some units cannot be delivered on schedule, which seriously restricts the work of all units. The general plan of the bridge of this project was completed in 65438+ 10 in XX, which seriously affected the development and progress of the construction drawing.

The compilation of the general plan can effectively ensure the design progress and quality of the project. These works should be completed in the preliminary design stage, which is of great significance to improve the design quality and progress and ensure the coordination and unity between the preliminary design and the construction drawing. In the implementation of the project, according to the feedback from design and construction, it is constantly supplemented, improved and summarized to improve the quality of the general plan.

Second, understand the local customs, strengthen the understanding of the design environment, and reduce duplication.

This project is a project outside the province, and the design environment, language communication and design concept are very different, which brings great difficulties to our design work. When I first arrived in Guizhou, I often didn't understand the owner's intention, didn't make a summary after the meeting, and didn't know how to carry out the work, which became a big obstacle to our design work. The preliminary design is mainly to solve two things: the project scheme and the project cost. Overtime in preliminary design is a common problem in current design. The first edition of the preliminary design budget of this project can be overloaded. Under the auspices of the owner, after many optimizations, various measures were taken to make the preliminary design budget meet the reporting requirements.

1, strengthen communication:

The feasibility study report is generally completed by the planning department, and it and the preliminary design department are generally two units or departments. In the process of compiling the feasibility study report, the level of designers, the research cycle and the needs of project establishment, what problems exist in the report, what problems are not clear in the study, and what should not appear in the report can not be found in the study report. If you make a preliminary design according to the contents provided in the report, you must take a detour. The preparation of this project is urgent, and the research on Sandu Interchange is not thorough, which leads us to spend a lot of time and energy in the preliminary design stage and construction drawing stage to study the necessity of interchange setting, hold many meetings and receive many criticisms.

2, pay attention to the project cost:

Due to the different geographical location and historical period of a project, the estimation index of each project will be slightly different, and occasionally individual anomalies will occur. It is necessary to pay equal attention to design scheme research and estimation, and guide scheme design research according to estimation indicators. This is of great significance to improve design quality and production efficiency.

In the field stage, we should arrange the collection and arrangement of material unit price and cost information as soon as possible, and strengthen cost analysis. The comparison between project feasibility and preliminary design can't stop at the level of project scale comparison. Only when the cost control is relatively reasonable, can it be transferred from outside to inside.

At the same time, it is necessary to strengthen the verification of estimation indicators. It is suggested to select representative projects and road sections, strengthen the design depth, reach the preliminary design depth and complete the budget estimate. Complete the comparison between budgetary estimate index and estimation index. Reflect the rationality of the estimated amount through representative projects.

3. Arrange engineering geological remittance in advance;

Geological route selection is a very important factor in mountain roads. If there is an engineering geological intersection map of 1: 1 000 in the corridor at the drawing position, it is of great significance to improve the design quality and save the project cost. Therefore, it is suggested to arrange geological handover work in advance, just like arranging survey control in advance, which is very important to improve design quality, speed up progress, improve design level and save costs.

4. Strengthen the accuracy evaluation of topographic map and make full use of topographic map;

With the improvement and perfection of design means and the accuracy of basic data, it has brought great convenience to our design work, especially after the topographic map adopts aerial photography technology, the drawing accuracy is very high. How to make good use of it and give full play to its role deserves our consideration and study.

In the field stage, it is of great significance to select representative road sections for lofting, evaluate the accuracy of topographic map, reduce the workload of lofting, improve the design speed and reduce the cost within the scope permitted by the specification.

There are many route schemes in the preliminary design stage, and the workload of hydrological survey is heavy. It is very difficult to complete the hydrological survey of all route schemes along the whole line. Therefore, it is suggested that hydrological work should be carried out in three stages. In the first stage, the topographic map and mathematical model are fully used to calculate and analyze the bridge site and subgrade documents of the whole line, so as to guide the horizontal and vertical design of the route and the development of various disciplines as soon as possible. In the second stage, the actual hydrological survey is carried out on the important sections and bridges of the recommended scheme, and the results of the first stage are revised according to the analysis results; The third stage is planned to be completed in the construction drawing stage, mainly to further improve the work in the second stage and comprehensively revise the hydrological report. This will help to save resources and costs, reduce work intensity, speed up the progress, and reduce the constraints of hydrological work on the progress of the project.

5, pay-off, investigation:

The mountainous expressway has complex terrain, dense vegetation, difficult lofting, high cost and slow progress. In order to control the accuracy of middle pile survey and cross section, side piles are added to the whole line, which effectively ensures the accuracy of survey and survey, but it also increases the difficulty and workload of lofting, affects the lofting speed and increases the lofting cost.

The route of this project passes through ethnic minority areas, with backward economy and remote location, which brings great difficulties to living and living. The work place and residence are far away, and the time spent on the road often reaches 3 or 4 hours, and the effective working hours are extremely short. The members of the project team overcame various difficulties and completed the field work of the project.

6, norms, habits:

Design specification is the rule of our designers and the basis of our design work. China is vast in territory and abundant in natural resources, with vast territory and huge differences in topography and climate. How to combine ministerial-level norms with the provincial conditions of any province is our research topic. A province's regional characteristics, design concept, construction level and management level will all form a province's characteristics and habits. When we first arrived in Guizhou, there were many unaccustomed places, which made us take many detours and do a lot of repetitive work. For example, if the owner requires that the middle filling height is less than 20 meters, the subgrade scheme should be adopted, and the middle filling height should be 20 ~ 30 meters. If the topographic and geological conditions are good, the subgrade scheme shall be adopted; According to the research results, the road sections over 30m should be selected reasonably. These ideas and concepts are unreasonable in our province, and we will adopt the bridge crossing scheme. Differences and unaccustomed are enormous. Therefore, it is of great significance to summarize the practical experience of expressways in the past decades and improve the local norms of our province under the framework of ministerial norms, combined with the characteristics of topography, geology and climate in our province, to guide our design and highway construction.

7. High cost and difficult to control:

This project is a provincial project with high cost and great difficulty in cost control. For example, the site acceptance of the construction drawing of this project is divided into three times: pre-acceptance of survey and design, pre-acceptance of geological exploration and site acceptance of construction drawing. The conference fee, consulting fee, accommodation fee and transportation fee are extremely high, which invisibly increases the design cost and seriously affects the design progress. From February of XX to the end of April of XX, at the request of the owner, I went to Guizhou for a meeting and completed other work 18 times, which greatly interfered with the design work of our institute and greatly affected the design progress of our institute.

With the leadership of the institute and the joint efforts of all designers, this project has made great efforts and successfully completed the design work of this project.

Summary of Geological Survey Work 3 Summary of Annual Work of Trade Unions in Investigation Institute In the past xx years, under the leadership of trade unions and the Party Committee of Investigation Institute, guided by the XX spirit of the Party and Theory of Three Represents Theory, closely surrounding the central work of our institute, combined with its own characteristics, we have highlighted the functions of trade unions in participating in the discussion of state affairs and safeguarding rights and interests, given full play to the intelligence and enthusiasm of employees in management, actively promoted democratic management, activated employees' anger through various activities, and enhanced the cohesion and combat effectiveness of the team, thus achieving the annual work goal of our institute.

First, strengthen the construction of trade unions themselves. At the beginning of the year, we held the second plenary meeting of the Eighth Workers' Congress and the trade union members' congress in accordance with the requirements of the articles of association, listened to and deliberated the annual work report of the hospital, the trade union work report and the trade union financial revenue and expenditure report, and earnestly performed the basic functions of the congress. This year, according to the actual situation and work needs of various departments, we re-elected the chairmen of the survey consulting company and the grass-roots branch of the first geotechnical company. In addition, we also hold regular working meetings of chairmen of grass-roots division of labor, check the activities of grass-roots branches, timely inform the work of our hospital, understand the ideological trends and requirements of employees, and effectively promote the work of trade unions. In order to continuously improve the professional level of trade union cadres and improve the quality of trade union work, we actively organized branch chairmen to participate in two training courses for trade union cadres arranged by the trade unions of this bureau. Through study, we have broadened the thinking and vision of trade union cadres and laid a good foundation for further improving the overall level of trade union work in our hospital. In order to give full play to the role of trade union organizations, we timely adjust the working mechanism, enhance the autonomy of grass-roots division of labor, and organize activities suitable for their own characteristics according to their own production conditions, giving full play to the role of trade union organizations.

Second, actively promote democratic management. Since the beginning of this year, the trade unions in our hospital have cooperated with the administrative management, started with institutionalization and standardization, fully exerted the democratic management and supervision functions of the workers' congress, broadened the channels for democratic participation, and built a solid platform for workers to participate in and discuss state affairs and concentrate their collective wisdom. In the system revision, we extensively solicited the opinions of employees. For example, when formulating the Regulations on Employees' Rewards and Punishment, we listed all kinds of punishments one by one, printed an opinion collection form and sent it to every employee representative, so that everyone could decide how to punish each punishment. Finally, the collected opinions were summarized, and a complete reward and punishment system was formed, which was widely recognized by employees. In addition, in the process of formulating rules and regulations such as "Attendance Management Regulations" and "Employee Paid Vacation System", the draft system was also sent to employee representatives in advance, and it was revised repeatedly according to the opinions and suggestions put forward by employees. We should listen carefully to the opinions of employees in all decisions involving their immediate interests. For example, on the issue of canceling the women's bathroom, the college repeatedly solicited the opinions of employees on the basis of in-depth investigation, and finally came up with a satisfactory solution, which not only eased the tension of office space, but also ensured the welfare of female employees. The Party Committee of our hospital not only allows employees to directly participate in the formulation of various policies and systems, but also fully mobilizes employees to participate in the management of our hospital more deeply. This year, a large-scale employee satisfaction survey was carried out, and a questionnaire survey was conducted among technical personnel in our hospital, so as to grasp the needs of employees in time, listen to their voices, and understand the shortcomings in our production, management and technological progress, which is beneficial to our party Committee and team. Recently, in combination with strengthening the construction of the party's ruling ability, our hospital has held a big discussion in the whole hospital, so that all the staff can jointly find out the gap in the management and development of our hospital and put forward reform suggestions. Through extensive and in-depth discussions, we not only found the urgent problems to be solved, but also further unified our understanding and enhanced our joint efforts. In addition, we pay attention to ensuring the democratic supervision right of our employees. For example, in the assessment process of organ target management, the grass-roots employees' recognition of the work of organs and departments is regarded as an important assessment index, and the organs and departments are also required to come up with specific rectification measures for the problems raised by grass-roots employees, and finally, together with the implementation of the rectification measures, they are fed back to the comrades or departments who put forward their opinions. This year, the second-level democratic management of all production units in our hospital has also achieved good results, further moving towards institutionalization, standardization and regularization, especially in bonus distribution, career development and departmental management, fully respecting public opinion. For example, when the survey consulting company worked out the bonus distribution scheme, after preliminary discussion, most employees thought that the distribution scheme of individual posts was unreasonable, so the company's leadership team fully listened to the opinions of employees, revised the distribution scheme, and obtained the consent of the majority through voting. In addition, the internal management systems formulated by the consulting company, such as "Main Engine Grading Assessment Method", "Workload Accounting Method" and "Supplementary Provisions on Indoor and Outdoor Industry Quality Control", were also implemented after repeated discussion and revision by the civil engineering management team, and the practice proved that the effect was good. The distribution plan of Geotechnical No.1 Company was also formulated after two revisions according to the opinions of the Civil Administration Group. In order to listen to the opinions of employees at different levels more widely, they also increased the members of the people's management team, and reviewed and adopted a number of internal management systems in terms of quality, safety, project progress and labor discipline. Especially on the issue of equipment management, employees generally think that the old management mode should be changed, so the company instructed the relevant personnel to write the equipment management method, but in the process of submitting it to the civil engineering management group for discussion, it was finally rejected because of great differences of opinion. In order to further promote this work and give full play to the potential of the equipment, recently, Geotechnical No.1 Company conducted a questionnaire survey on all employees, solicited opinions extensively, and invited employees to make suggestions on the management and development of the company. The participation enthusiasm of employees is very high, and many good suggestions are put forward. In addition, other units also have some good practices in secondary democratic management, so I won't list them here.

Through the summary of the above aspects, it fully reflects that the democratic management of our hospital is gradually advancing to a deeper level and a higher level, which not only effectively mobilizes the enthusiasm of employees to participate in the discussion of state affairs, but also ensures the power of democratic supervision of employees, better plays the role of democratic supervision in promoting various management work, and creates a good atmosphere for the development of our hospital.

Third, carry out colorful cultural and sports activities for employees. This year, in cooperation with various sports competitions organized by the bureau's trade unions, employees were organized to engage in bowling, badminton, table tennis and summer swimming activities in addition to intense production. In the bureau system competition, our college won the women's bowling team championship and the men's table tennis team fifth. During the "March 8th" Festival, we also organized female workers in our hospital to hold a fun sports meeting. In the second half of the year, in cooperation with the 25th anniversary of the College, the cultural and sports activities of the faculty and staff will be pushed to a climax. In September, we held a talent show for employees, and both working employees and retired employees actively participated. Everyone took out their proud calligraphy, photography, painting, philatelic works, various collections and family photos to participate in the exhibition. On the eve of the anniversary, we also organized a women's basketball competition and a tug-of-war competition by department. In particular, a cultural performance was arranged for the annual meeting, which was written and performed by our staff. These activities not only show the versatility of our faculty in many ways, but also effectively guide the enthusiasm of faculty to actively participate in cultural and sports activities. Compared with last year, our cultural and sports activities this year are richer in content and wider in scope, which are generally welcomed by employees.

Fourth, care about the lives of employees. Based on the concept of "the interests of the masses are no small matter", the trade union of our hospital regards caring for the lives of employees and seriously solving their difficulties as an important task to enhance the cohesion and centripetal force of the workforce. This year, the female workers in the hospital were specially organized for physical examination. For employees who have difficulties in life, the trade union will lend a helping hand in time and give subsidies. This year, the subsidy for difficulties is more than 20,000 yuan, taking care of more than 90 employees. For employees hospitalized due to illness and employees whose families died, the hospital trade unions visited the hospital or at home, which made the employees feel the care of the organization. Because many departments in our hospital need field work and construction, the working and living environment is relatively poor. Therefore, during bad weather and holidays, the trade union should accompany relevant leaders to the construction site to express condolences and check the implementation of safety production. Every time employees get married, the institute's trade union will send a gift and attend the ceremony in person. In case of major traditional festivals, the college trade union also cooperated with the Youth League Committee and relevant departments to organize single youth gathering activities, which made employees feel the collective care and warmth and enhanced the cohesion of the team.

Summing up the work in the past year, the trade unions in our hospital have made some achievements by giving full play to their roles and performing their functions under the circumstances of few personnel and heavy tasks. But realistically speaking, there are still many deficiencies in our work, such as the regularization and institutionalization of democratic appraisal and supervision, the lack of in-depth popularization of organizing and guiding employees to carry out healthy and beneficial collective activities, and some deficiencies in ideological education and professional skills training for employees. To this end, we should focus on the following aspects next year:

1. Give full play to the functions of trade unions, continue to vigorously promote democratic management, further play the role of vigilante groups, and make their activities regular and institutionalized.

2. Strengthen the self-construction of trade union organizations and improve the policy and theoretical level and working ability of trade union cadres at all levels.

3. Actively participate in various reforms and corporate culture construction, and assist the party and government departments in publicity and education.

4. Work closely around the production and operation center, actively cooperate and take the initiative to serve.

5. Carry out mass workers' cultural and sports activities according to local conditions and do a good job in the construction of workers' homes.

6. Actively do good deeds for employees, do practical things, and constantly enhance employees' sense of belonging and cohesion.

In short, in the new year, under the leadership of the superior trade union and the hospital party Committee, we will conscientiously do all the work and make due contributions to the reform and development of the hospital.
