Description

An engineering survey benchmark that automatically keeps vertical

technical field

The utility model relates to the technical field of engineering survey benchmarks, in particular to an engineering survey benchmark that automatically keeps vertical.

Background technique

Engineering measurement and design related to engineering construction in various industries, such as railway, highway engineering measurement, water conservancy engineering measurement, bridge and tunnel engineering measurement, construction engineering measurement, mine measurement, marine engineering measurement, military engineering measurement, 3D industrial measurement, etc., commonly used The method is to use the level instrument and the benchmark to measure together. When measuring, the benchmark is required to be perpendicular to the horizontal plane to ensure the accuracy of the measurement. At present, in the measurement, the benchmark is often manually controlled, and the correct angle of the benchmark is guaranteed by the operator's feeling. Therefore, the topography The complexity of the project is inconsistent with the technical level of the operator. It is difficult to guarantee the verticality of the benchmark pole and the horizontal plane, which leads to inaccurate measurement and the construction quality cannot be guaranteed. In this case, the obtained data is not accurate enough and needs to be re-measured, which will greatly waste It is a waste of human, financial and material resources.
