Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a land settlement measuring device for highway construction. Background Art

[0002] Settlement refers to the vertical deformation or sinking of foundation soil caused by compression under the action of building load. Uniform settlement generally does less harm to buildings, but when it is too large, it will reduce the elevation of the building and affect its use. Uneven settlement is more harmful to buildings, causing additional stress in the building and causing cracks, or even partial component breakage, endangering the safety of the building. When building a highway, if the load of the highway causes the land to settle, it will cause an uneven road surface, affecting transportation. Therefore, it is necessary to inspect and detect land settlement on the highway.

[0003] In the existing land settlement measurement process, the measuring equipment is placed on a bracket to provide stable support. The bracket is generally composed of a support rod and a placement table. A tip is set at the bottom of the support rod to facilitate ground plugging and fixing. When the support rod is unfolded, the whole is in an inclined state, so that the bottom tip is also in an inclined state. When the soil at the surveying and mapping site is hard, the tip part in the inclined state is difficult to insert into the ground under the action of external force or the insertion depth is insufficient, making it difficult to fix the bracket, and the surveying and mapping equipment is easy to slip, which is inconvenient for measurement and the measurement data is prone to errors.

[0004] Therefore, in view of the problems that when the measuring equipment is used in conjunction with a bracket in the above-mentioned land subsidence measurement, the bracket is difficult to fix, the surveying and mapping equipment is easy to slip, it is inconvenient to measure and the measurement data is prone to errors, a device with optimized structure, convenient adjustment, and easy fixation on the ground is designed to cooperate with the installation of surveying and mapping equipment for measurement to ensure measurement accuracy, so as to solve the above-mentioned problems.
