Abstract

The invention discloses an automatic monitoring device for foundation settlement. The device comprises a foundation body, a water carrying box, a pressure cavity and a floating ball, a steel support and a settlement plate are arranged at the bottom of the foundation body, the other end of the settlement plate is connected with a waterproof compression plate through a connecting piece, and the waterproof compression plate is located in the water carrying box. The bottom of the water carrying box is connected with a pipeline, the other end of the pipeline is connected with a liquid storage tank, a floating ball liquid level meter is arranged in the liquid storage tank, and the side wall of the longitudinal structure of the pipeline is connected with a horizontal frame. Automatic monitoring for foundation settlement can be realized. The two ends of the pipeline are connected with the water carrying box and the liquid storage tank, the liquid level in the liquid storage tank serves as a stable reference point, when a foundation settles, downward pressing force forces the waterproof compression plate to press downwards, the liquid level rises under the action of pressure, settlement data are obtained by calculating the height difference of the liquid level surface, and follow-up specific problem analysis is achieved.

Description

technical field [0001] The invention relates to the technical field of survey equipment, in particular to an automatic monitoring device for foundation settlement. Background technique [0002] Foundation settlement refers to the subsidence of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. Excessive settlement, especially uneven settlement, will cause the building to tilt and crack so that it cannot be used normally. [0003] There are many factors for settlement. From the perspective of internal factors, the settlement of the foundation may be due to the compression deformation of the pores in the soil layer, which causes deformation in the vertical direction. From the perspective of external factors, it may be due to the additional stress of the foundation under the action of external loads. , so that the original stress of the land has changed, and in engineering construction, highways, bridges, tunnels...
