Detailed explanation of engineering survey terms

Engineering survey refers to all kinds of survey theories, methods and technologies adopted in the survey, design, construction and management stages of engineering construction. What does engineering survey mean? The following is my explanation of engineering survey for your reading!

The meaning of engineering survey refers to all surveying and mapping work in engineering construction, including all kinds of surveying work in engineering construction survey, design, construction and management stages. Engineering survey is divided into engineering control survey and topographic survey in survey and design stage, construction survey and equipment installation survey in construction stage, and completion survey in completion and management stage.

According to its working sequence and nature, engineering survey can be divided into: engineering control survey and topographic survey in survey and design stage; Construction survey and equipment installation survey in the construction stage; Maintenance survey in completion survey, deformation observation and completion management stage. According to the engineering construction object, it is divided into: architectural engineering survey, hydraulic engineering survey, railway survey, highway survey, bridge engineering survey, tunnel engineering survey, mine survey, urban municipal engineering survey, factory construction survey, military engineering survey, marine engineering survey, etc. Therefore, engineering survey covers all sectors and aspects of national economic construction and national defense construction.

The training goal of engineering survey is to cultivate advanced technical application-oriented professionals who master the basic theoretical knowledge and basic surveying and mapping skills necessary for surveying engineering specialty and engage in engineering construction survey. Focusing on the talent training goal of higher vocational colleges, the major of engineering surveying technology is based in Sichuan and faces the whole country, and cultivates high-skilled talents who can develop morally, intellectually, physically and aesthetically, master the basic theory and skills of surveying, and be engaged in all kinds of engineering surveying, cadastral surveying production, management and service. When students graduate, in addition to obtaining academic certificates, they must also obtain vocational skill appraisal certificates issued by at least one country.

Core competence of engineering survey: survey skills in the stages of engineering planning, design, construction and operation management.

The main courses of engineering survey course.

Looking forward to 2 1 century, engineering survey will be greatly developed in the following aspects:

As a multi-sensor integrated system, measuring robot will be further developed in artificial intelligence, its application scope will be further expanded, and its image, graphics and data processing capabilities will be further enhanced.

In deformation observation data processing and large-scale engineering construction, knowledge-based information system will be developed and further combined with geodesy, geophysics, engineering and hydrogeology, civil architecture and other disciplines to solve various problems such as safety monitoring, disaster prevention and environmental protection during engineering construction and operation.

Three-dimensional measurement, geometric reconstruction and quality control of large-scale complex buildings and equipment, as well as modern industrial production have higher and higher requirements for automatic flow, production process control, product quality inspection and monitoring data and positioning, which will promote the further development of three-dimensional industrial measurement technology. Engineering survey will be extended from woodworking survey and three-dimensional industrial survey to human scientific survey.

Multi-sensor hybrid measurement system will be rapidly developed and widely used, such as the integration of GPS receiver with electronic total station or measuring robot, which can carry out various measurement work without control network in a large area or even in the whole country.

GPS and GIS technologies will be closely integrated with engineering projects and play an important role in the integration of survey, design and construction management.

In human activities, engineering survey is everywhere, all the time. As long as there is construction, engineering survey will inevitably exist, so its development and application prospects are broad.
