2. Carry out contact measurement outside the cave and inside the hole: calculate the coordinates and elevation of the control point of the hole according to the results of the control measurement outside the hole, and calculate the different coordinates and elevation of the design of the point to be fixed in the hole according to the design requirements, and stake out the point to be fixed in the door, which is the contact measurement of the outside of the hole and the inside of the hole.
3. Carry out control measurement in the cave: the control measurement in the cave mainly includes the plane control measurement in the cave and the elevation control measurement in the cave.
4. Carry out construction measurement in the tunnel: The construction measurement in the tunnel mainly includes: the construction lofting of the door.

Anonymous users2024-02-04Hello pro is very happy for you: the tunnel survey plan is one of the documents that must be prepared before the tunnel construction, including the following basic contents: 1 Project Overview:
3. Measurement principles: Clearly imitate the principles and methods of various measurement work, such as control measurement, plane measurement, curve control measurement, etc. 4 Measurement Tasks:
Clarify the purpose, content and implementation requirements of each measurement task, such as tunnel axis measurement, section measurement, slope measurement, etc. 5. Measuring equipment: list the measuring instruments and equipment that need to be used, and explain their parameters, performance and accuracy.
6. Surveyors: Clarify the number, responsibilities and requirements of surveyors to ensure the scientificity and accuracy of surveying work. 7 Measurement Procedure:
Describe in detail the steps and processes for each measurement job, as well as the precautions and safety measures that need to be taken. 8. Data mega processing: Explain the processing methods and calculation formulas of the measurement data to ensure the accuracy and reliability of the measurement results.
9. Measurement report: According to the actual situation, prepare the measurement report and analyze and evaluate the results, so as to provide a scientific basis for the subsequent construction of the first large leased tunnel. It should be noted that the content of tunnel measurement schemes of different types and locations may be different, and should be formulated according to the actual situation.
Hope it can help you dear.
Tunnel measurement, total station is to control linearity, convergence meter to measure convergence, GPS cost is too high to be coordinated. The level can measure the monitoring and measurement of the vault sinking and the elevation control of the arch construction. >>>More
Ground control measurements.
Ground control surveys mainly include plane control surveys and elevation control surveys. The main task of plane control measurement is to determine the plane position of each opening control point, so as to guide the design direction underground according to the opening control point, guide the tunnel excavation, and can penetrate according to the specified accuracy. >>>More
The excavation of the tunnel entrance is planned to adopt mechanical construction, and the excavation of the tunnel body uses a simple self-assembling trolley to drill the hole, and the multi-section millisecond detonator is detonated, in order to improve the smooth blasting effect of the peripheral eye, the peripheral eye is detonated with a special detonator. The tunnel ballast is loaded with a loader, and the dump truck cooperates with the ballast. The secondary lining concrete pouring of the tunnel uses an integral large formwork trolley with a length of 12m, and the concrete is mixed in a centralized manner at the mixing station, transported by a concrete transport vehicle, and pumped into the mold. >>>More
Let me tell you, I am the champion in this industry, this profession, I personally think that surveying can do the work of the constructor, but the constructor may not be able to do the work of professional surveying, and the measurement technology is stronger. It also depends on whether you want to do the measurement of housing construction, or the measurement of roads and bridges, or the measurement of hydraulic engineering, although they are all measurements, the calculation of the main measurement lofting is almost the same. However, different projects, the construction organization is still slightly different, and the technical requirements are also different As for whether the job is good or not, it depends on the family relationship of the landlord. >>>More
Tunnels, for the people of the construction unit, is a dangerous and magical work. My understanding is that it should be digging a hole first, and then erecting a frame, concrete or something. Let's hear what the pros have to say! >>>More
