What problems do we need to pay attention to in engineering surveying?

Strengthen the re-testing work in the construction survey to reduce the occurrence of errors.

In the surveying practice, the students do not have enough understanding of the retest work, which is an indispensable work to ensure the quality of construction projects, and it is also an important part of the construction data. The purpose of the retest is to check whether the floor plan position and elevation data of the building meet the design requirements. Most of the construction survey accidents that occurred in the past were caused by neglecting the re-testing work.

The retest content mainly includes the following aspects:

1 Retest of raw data. The construction surveyor should conduct a comprehensive check on the data, elevation and control measurement data on the design drawings, and carry out the necessary re-testing and proofreading of the survey pile handed over by the design unit to avoid unnecessary engineering losses caused by the inconsistency between the design data and the survey mark.

2 Retest of building positioning. According to the building red line pile provided by the planning department, after the building is positioned, the corner coordinates of the building should be remeasured according to the positioning control pile, and the plane geometric size and elevation are consistent with the data on the design drawings and whether they meet the engineering accuracy requirements. Problems should be corrected in a timely manner.

3. Re-test of leveling points. After the introduction of the leveling point on the construction site, it is usually necessary to make two round-trip observations to ensure accuracy.

4. Review of design drawings and noisy objects. Before measuring and designing, we must read the drawings carefully, and conduct a comprehensive check on each size and data on the actual drawings to prevent the use of wrong design data to cause the building to "not intersect" in the plane size and vertical elevation, causing serious consequences. For example:

Check whether the axis position, elevation size and symbols of the building plan and elevation plan and section are consistent. If necessary, the main dimensions on the drawing should be copied from the measurement record book, so that they can be found and used at any time, and the wrong design data and measurement marks must not be used by memory.

5 Re-measurement of observation records. For the field measurement records, another surveyor should be replaced to review the school team when returning to the room, and the errors should be solved in time.

Construction surveying is an indispensable and important part of the construction process. Therefore, students should improve their hands-on ability to lift liquid and use their brains in the process of measurement practice, standardize the operation process, reduce errors and avoid errors.

If there is a well-designed drawing, and it is feasible according to the site, it must be carried out according to the design, the foundation of the excavation must be excavated first, and the design coordinates of the foundation should be calculated and staked out to the field.

industrial and civil buildings; Plane Positioning -- Axis line. Vertical Elevation -- Elevation line.

Municipal engineering installation; Plane Positioning -- Axis line. Vertical Elevation -- Elevation line.

Good surveyor. Surveying pay-off workers, as the name suggests, can be said to be workers, while engineering surveyors have technical levels and titles, and can be used as assistant engineers and engineers.

The latter has a high gold content, because I have a colleague who graduated from engineering surveying, and also has an engineering surveying certificate, but it is useless, and the measurement pay-off worker, which contains pay-off construction matters, is higher than the former technical content, and the current water conservancy surveying pay-off technicians are relatively lacking, or more popular, I think the latter is better.

Engineering surveying is the use of conventional geodesy, satellite navigation and positioning surveying, photogrammetry and remote sensing, map mapping and geographic information system, special surveying and other surveying and mapping technology methods to provide guarantee and service for the construction and operation management of various projects. Its business areas mainly include engineering control surveying, topographic and landscape surveying and mapping, construction lofting and testing, and deformation surveying. Its services cover a wide range of fields, such as construction engineering, municipal engineering, transportation engineering, energy and resources engineering, national defense and scientific research engineering.

Engineering surveying is a variety of surveying work carried out in the survey, design, construction and management stages of engineering construction. It is directly for the survey, design, construction, installation, completion, monitoring and operation management of a series of engineering processes for various construction projects. Surveying pay-off workers are a type of engineering surveyor.

There are relatively few instruments used to measure pay-off. The former tends to apply a variety of sophisticated electronic instruments, covering a wider range of senses. The latter is used more in the specific construction of the construction site.

Hope. Registered cost engineer refers to the state granted the erection of the car and approved to practice after registration, specifically to accept a department or a unit designated, entrusted or hired, responsible for and assist in the valuation, pricing and management of the project cost, in order to safeguard their legitimate rights and interests of the engineering economic professionals. The state implements the cost engineer qualification system in the field of engineering cost. All units and departments engaged in the construction, design, construction, engineering cost consulting, and engineering cost management of engineering construction activities must be equipped with professional and technical personnel with cost engineer qualifications in valuation, evaluation, review (nuclear), control and management.

Surveying and mapping instruments, tripods, tower rulers, prisms, walkie-talkies, steel tape measures, paper and pens, of course, record bags, umbrellas, and sunscreen these days, hehe.

It's all the same, it's all field work. Whichever unit has good benefits, you will go to which unit, which is the most affordable.

Marine surveying is the most profitable, because of the high risk factor of working at sea, followed by scientific investigation and measurement, roads, bridges, tunnels, pipeline measurements, etc.!

Summary. Hello, dear, I am happy to answer for you: what problems can engineering surveying solve:

1. Measurement work in the planning and design stage of engineering construction. Construction surveys are carried out in important areas with poor engineering or geological conditions, and the stability of the strata is observed.

Dear, hello, I am glad to answer for you: engineering surveying can solve the problem: 1. Surveying work in the planning and design stage of engineering construction.

Construction surveys are carried out for important areas with poor engineering or geological conditions, and the stability of traveling strata is observed for elimination.

2. Measurement work in the construction stage of engineering construction. At this time, the first vertical tour should be designed buildings (structures) according to the construction requirements on the site, as the basis for on-site construction. 3. Measurement work in the stage of engineering construction operation and management.

During the operation of engineering buildings, in order to monitor their safety and appraisal conditions, understand whether the design of liquid burial is reasonable, and verify whether the design theory is correct, it is necessary to regularly observe the position stability, subsidence, tilt and swing of the remaining buried pins of the buildings and structures, and timely feedback measurement data and charts.

The development of engineering surveying is trending: 1. The measurement robot will be further developed as a multi-sensor integrated system in the virtual surface of artificial intelligence, and its application scope will be further expanded, and the ability of image, graphics and data processing will be further enhanced; 2. Engineering surveying will be extended from civil engineering surveying and 3D industrial surveying to human scientific surveying, such as microscopic measurement and microscopic image processing of various organs or parts of the human body; 3. The multi-sensor hybrid measurement system will be rapidly developed and widely used, such as the integration of GPS receiver with electronic total station or measurement robot, which can carry out various measurement work without control network in large regions and even countries.

Summary. Engineering surveying can solve the problem of survey data collection and processing of surveying and mapping projects.

What problems can engineering surveying solve in surveying and mapping engineering?

Engineering surveying can solve the problem of survey data collection and processing of surveying and mapping projects.

In terms of engineering construction, the use of surveying and mapping technology combined with the actual situation of the construction site and the terrain and engineering conditions, the construction control network is built at different locations, the differentiated measurement and lofting method of surveying and mapping technology is used to accurately convert the design content into the actual position of the ground, and the structures and buildings on the construction site are regularly measured to generate chart data, so as to more conveniently grasp the subsidence, inclination and other conditions that may occur in the construction, so as to ensure the safety of construction. In addition, surveying and mapping technology can also be applied to modern geological engineering surveying, mineral resource exploration, etc. In the new era, the rapid development of modern surveying and mapping technology is of great significance to improving the engineering surveying level of the construction industry, which is conducive to the comprehensive development of China's construction industry and promotes the improvement of the engineering surveying level.

With the diversification of construction forms and the development trend of the complexity of the measurement environment, construction projects have higher requirements and standards for measurement technology. Only by continuously strengthening and developing surveying and mapping technology and insisting on innovation and research can we better promote the surveying work of construction projects in China.
