2. Speech by Secretary Li of Dali County Education Bureau

1. This project belongs to the first high school in Weibei and is one of the top ten livelihood projects in Weinan in 215. Now there are problems in foundation construction.

2. The construction and supervision units are required to fully respect the expert opinions.

3. The construction and supervision units are required to carry out the construction in strict accordance with the experts' opinions after the experts give the rectification plan.

third, Gao Li, the director of the supervision unit, introduced the basic situation of pile sinking

1. Basic situation: the pile test construction of this project began in February, and the test results of pile test in the office complex and the B area of the East Teaching Building met the design requirements, and no pile sinking was found.

2. during the pile construction of the east teaching building and the experimental building, it was found that the pile settlement phenomenon became more and more serious during the construction of the office complex building. After the exploration by the geological exploration team of Dali County, the cause of direct settlement was not found.

4. The participating units express their views and opinions on the settlement of foundation piles

1. Yang Zhouwen, a pile foundation construction unit, spoke that the water content of the soil around the piles is too high at present, and the third and fourth layers of soil are too soft to bind the piles, resulting in collapse.

expert's question: how much mud does the auger bring out?

answer: this phenomenon is not serious because of the shallow excavation of foundation pit.

2. The investor spoke on behalf of Wang Mao Sheng, and personally analyzed the reasons for the sinking of the pile. The gravity of the soil and cement increased the density, and the lower soil layer was weak, resulting in the sinking phenomenon.

3. Wu Shengli, a survey unit, made a speech. After verifying the soil quality of the stratum, no change was found. The soil in the 2nd, 3rd and 4th layers contained a large amount of water, and the surrounding soil was in a fluid plastic state due to disturbance, so there was no constraint on the pile body and there was no problem in the bearing stratum.

4. Design unit's speech

Dong Chao: The office complex building has one basement and six floors above ground, with a pile depth of 8.m and a dummy pile head of 5mm. After inspection, the building has a large settlement, with about 5% of the piles sinking. Experts need to solve the problems: first, if the pile body sinks as a whole, which method to take; Second, if it sinks during piling, it is recommended to backfill. It is necessary to do local inspection, and the sinking is mainly caused by the construction process.

Wang Shaoyong: On May 5th, it was found that half of the piles in the site had settlement, and the effective pile length was not clear after testing, so the testing results were very important.

Experts ask questions: 1. Pile spacing, buried depth of foundation, calculation basis of pile spacing and absolute elevation? 2. The pile spacing of the second soil layer should be different from that of the third soil layer. What is the bearing capacity of a single pile? Pile spacing bearing capacity?

Answer: 1. The pile spacing is 1.3m, the buried depth of foundation is -4.7m, and the pile spacing meter

is calculated according to the second floor.

5. Ask the expert group to review the above problems and work out solutions. 4

The new code stipulates that the bearing capacity of single pile needs to be tested.

Zhang mantang, the testing unit, made a speech: the test pile was tested in March, and no settlement was found, which met the design requirements, and the low strain met the requirements. The bearing capacity value of single pile should be strengthened in the later tests.

expert's speech: the testing unit should do low strain first, and then do static load test. If the testing conclusion is unqualified, it should make up the pile.

2. Yang-Zhou Wen, a pile foundation construction company, spoke about cement grade P.C32.5, mixing amount of 15% and drilling speed of 1m per minute.

3. Li Hongmao, the investor's representative, made a speech on the sinking of the pile with Luoyang shovel in the experimental building. The sinking ratio is 3%, and the sinking amount is mostly 3 ~ 5 cm, with individual phenomena of 1m, 7 ~ 8cm and 2m.

expert's speech: I visited the site on Wednesday, and found that the geological conditions of the project are poor, the hard load of the second layer of stratum soil is better than that of the third layer, and the overall pile sinking is serious, with a regular decline. The foundation pit excavation of the office complex building and the experimental building is heavy, and the construction of two pile foundations is close to the water level.

Expert Xu Zhangjian's speech:

Causes of subsidence: the construction disturbed the soil, and the soil strength was lost, and the subsidence and mud output were in a balanced state.

Solution:

① Skip piling, and the interval between piles will be longer, which may make the construction more difficult and the construction period longer.

(2) For the piles that have caused sinking, the sinking amount of each pile shall be counted by Luoyang shovel

, and the pile shall be supplemented with concrete to reach the designed pile top elevation. However, the piles of the office complex building have entered the sixth floor of the stratum, and the piles that have not entered the fifth floor are required to enter the fifth floor to be used as the bearing stratum.

Expert Yang Honggui's speech:

Sinking reason: The surrounding soil is too poor, and it will form a big belly or pile up and sink under the influence of disturbance. Will there be a broken pile due to insufficient cement in the lower pile?

solution: 3 ~ 5 cm of sinking pile can be compacted with plain concrete or cement soil; If the subsidence exceeds 8cm, do low strain first, then do static load test, and finally do pile repair treatment if the detection is unqualified; The design and calculation of pile spacing shall be checked according to the third floor.

Expert Zhu Shenyang's speech: Attention should be paid to the construction interval or sequence.

Li Qinghai, an expert, said:

The reasons for subsidence: the analysis of the reasons for subsidence is consistent with the opinions of all units. The loss of strength of soil is caused by the destruction of structure.

solution: construction sequence and method arrangement; Jump row or alternate row piling. Design and testing units do single pile load test; The sinking pile of the experimental building is tested to verify the bearing capacity and record the maximum bearing capacity.

If it is made as mentioned above, the measures of pile filling are feasible; If the test result is pregnant, the above remedial measures need to be considered.

Expert Zheng Yongqiang's speech:

Causes and solutions of subsidence:

1. Whether soil and cement are separated;

2. The deformation of three and four layers of soil. Soil can be reinforced to solve the deformation problem.

3. Will there be separation between soil and cement at low strain? If the pile body is complete, problems such as deformation can be solved.

VI. Does the contractor have any supplementary explanation on the sinking of the pile and related matters in the future construction?

Yang Zhouwen, the pile foundation construction unit:

1. Two piles are constructed separately in a foundation pit, and the pile drivers are placed in the east and west, which is longer than the distance between the pile drivers in the two pits, and the impact will not be too great.

2. The excavation of the foundation pit is shallow, and the probability of subsidence is small. According to the previous "Z" shape and jumping row, there is little change, and the soil water content is small and the subsidence is small, while the soil water content is large and the subsidence is large.

3. Deep mixing will not lead to broken piles, and experts mean broken ash, which is unlikely.

4. The pile spacing is large, and the water level is saturated, so it is not easy to be treated by powder jet grouting pile.

5. mix soil and cement for reinforcement.

Liu Wei, the pile foundation construction unit:

According to the situation of jumping and driving in the past two days, there is not much change in the sinking with or without jumping and driving. Now the excavation of the west teaching building is shallow, the water content of the soil layer decreases, and the sinking without jumping and driving before is very small.

Expert Xu Zhangjian:

Jumping is mainly aimed at deep excavation, and shallow excavation can be avoided.

Expert Yang Honggui:

1. The deviation of pile position should be within the allowable range of specifications.

2. If there is no problem in the low strain detection, then do static load. If there is a problem in the low strain, it means that there is a problem in the pile.

Expert Li Qinghai:

1. The subsidence is mainly caused by poor geological conditions and shallow water level.

2. The construction scheme should be adjusted, and the construction should be staggered.

3. It is necessary to increase the detection of single pile bearing capacity and increase the batch, especially to consciously select sinking piles for detection and carry out small strain detection on sinking piles.

4. those with small subsidence can be tamped with cement soil, and those with large subsidence can be compacted with C15 concrete, and the pile should be supplemented under the water level.

demonstration conclusion: see the attached page for details.

VII. Speech by Wang Gandi, Quality Supervision Station

1. Change the foundation treatment form (subsequent pile foundation construction method and treatment method of completed piles).

2. The shallow excavation subsidence is light and the deep excavation subsidence is serious. Will the excavation be shallow? There is no problem on the surface, but the pile may have fallen from the second layer of soil. Increase the detection of piles, increase the detection of single pile bearing capacity, increase the detection batch of piles, and finally produce the test report.

3. treatment: if the pile is not cleaned up properly, how can it meet the design requirements? Whether the elevation of foundation pit of pile can be lowered.

VIII. Conclusion

Requirements:

① It is hoped that all contractors will ensure the quality of the project in strict accordance with relevant national or local laws and regulations, technical specifications and acceptance standards

② Always pay unremitting attention to the safety work

③ It is required that the construction unit do all the site preparation according to civilized construction site standards from beginning to end

④ It is hoped that all units will cooperate sincerely. Give a satisfactory answer for the people of Dali County

How to write the minutes of the demonstration meeting [Chapter 2]

On July 5th, 212, at 2:3 pm, the people's government of xx Town organized a demonstration meeting on the planning of the streetscape improvement project of xx Town in Ninghai International Pacific Hotel. The units attending the meeting included the County Development and Reform Bureau, Finance Bureau, Planning Bureau, Housing and Construction Bureau, Transportation Bureau, Water Conservancy Bureau, Agriculture and Forestry Bureau, Urban-Management Bureau, Landscape Bureau, Power Supply Bureau, Traffic Police Brigade and Ningbo Landscape Design and Research Institute.

leaders and experts attending the meeting listened to the planning and design scheme of Ningbo Landscape Architecture Design and Research Institute, and after careful study, the expert group thought that the planning had conducted in-depth analysis and research on the current situation of the main street in xx town, with detailed basic information and novel design concept, which was scientific, forward-looking and feasible, and was approved in principle.

At the same time, the expert group put forward a lot of constructive opinions and suggestions as amendments to further improve the planning:

First, the planning should follow the principle of integrity, make overall consideration of the existing urban features and future urban expansion direction, and formulate this design scheme in combination with the regional development planning of Sanmenwan in Ningbo, the construction standard of forest towns in Ninghai County, the overall long-term development planning of central towns, the overall planning of xx towns and the water environment construction planning of xx towns, so as to realize one-time planning and implement it step by step.

second, the planning should reflect the humanistic characteristics of xx. Park design should give full play to the gathering function of the square and show xx "reclamation" culture. Landscape sketches, billboards and other production should integrate 1

xx elements, especially the waterscape and stone landscape of xx, and be combined with the industrial layout of xx.

Third, the greening effect and economy should be considered comprehensively. Tree species should choose suitable local varieties. The maintenance cost of moving flower boxes and grass flowers is high, so it is recommended to plant deciduous trees.

4. The reconstruction of underground pipelines, how to deal with non-vehicular lanes and parking space should be considered in the pavement reconstruction. The renovation and upgrading of Dongxing Road and Changyue Road is the focus of this plan, which needs to be further optimized and refined.

5. River greening should be neat and natural, highlight the rural flavor, avoid artificial, and have a certain visual isolation function, and at the same time, it should not affect the drainage and flood discharge and the structural stability of river banks.

VI. It is suggested to unify the standards for building promotion and billboard setting, and guide them by means of government incentives.

VII. The investment estimation is too simplified, so it needs to be further refined. The greening estimation of each road should be recalculated according to the actual situation and scheme design. Pipeline laying investment should be included in the investment estimate.

How to write the minutes of the demonstration meeting [Chapter 3]

I. Format of the minutes of the meeting

The minutes of the meeting usually consist of the title, the text, the sender and the cc unit.

there are two kinds of titles. one is the name of the meeting plus the minutes, such as the minutes of the national rural work conference. Second, the organ that held the meeting added content and minutes, such as the Minutes of the Meeting of the Provincial Economic and Trade Commission on Turning Enterprises into Losses.

the text of meeting minutes generally consists of two parts.

(1) overview of the meeting. It mainly includes the meeting time, place, name, host, participants and basic agenda.

(2) the spirit and agreed matters of the meeting. Minutes of standing meetings, office meetings and routine work meetings generally include meeting contents, agreed items, and some can also outline the significance of agreed items. Minutes of working meetings, professional meetings and symposiums often include experiences, practices, opinions, measures and requirements for future work.

II. Three ways of writing meeting minutes

According to the nature, scale and topics of the meeting, there are roughly the following ways of writing:

(1) Centralized summary method. This way of writing is to describe and explain the basic situation of the meeting, the main issues discussed and studied, the understanding of the participants and the relevant matters agreed upon (including measures, methods and requirements for solving problems, etc.) in a general way. This writing method is mostly used to hold small meetings, and the issues discussed are relatively concentrated and single, and the opinions are relatively unified, which is easy to implement and the length of writing is relatively short. If there are many topics at the meeting, they can be listed in different articles.

(2) itemized narrative method. When holding large and medium-sized meetings or meetings with many topics, it is generally necessary to adopt the method of itemized narration, that is, divide the main contents of the meeting into several major issues, and then write them separately with labels or subheadings. This kind of writing focuses on horizontal analysis and elaboration, with relatively comprehensive content and detailed problems, which often includes the analysis of purpose, significance and status quo, as well as the elaboration of objectives, tasks, policies and measures. This summary is generally used for grassroots comprehensive understanding, deep
