Foundation settlement multi-ball-point detection method

Abstract

The invention discloses a foundation settlement multi-ball-point detection method, and belongs to the field of foundation settlement detection. According to the foundation settlement multi-ball-pointdetection method, through the arrangement of a multi-ball-point embedded rod, when foundation settlement occurs, a separation ball near the multi-ball-point embedded rod is subjected to sinking force,two self-separation hemispheres are separated from each other, the force of the two self-separation hemispheres acting on a pressure sensor is reduced, at the moment, the pressure sensor transmits asignal to the cloud, the cloud can roughly determine whether the foundation is settled or not and the settled part through cloud computing, and along with gradual increase of the foundation settlementcondition, a detection barbed rope is stretched to deform, so that the tip end of an embedded pricking needle is exposed, a fluorescent film ball is punctured, fluorescent liquid flows out, when a settlement determining part is maintained, after excavating, the severity degree of foundation settlement can be judged according to the fluorescence intensity generated near the multi-ball-point embedded rod, proper maintenance measures can be conveniently selected in time, and potential safety hazards are remarkably reduced.

Description

technical field [0001] The invention relates to the field of foundation settlement detection, in particular to a foundation settlement multi-ball point detection method. Background technique [0002] The settlement of the foundation is mainly due to the difference in the load of the building and the inhomogeneity of the foundation. The settlement of each part of the foundation or embankment is more or less inhomogeneous, which causes additional stress and deformation in the superstructure or pavement structure. If the uneven settlement of the foundation exceeds a certain limit, it will lead to cracking, skewing or even destruction of the building, such as cracks in the brick wall, clamping rails or slide rails in crane wheels, tilting of tall structures, deflection of machine shafts, and pipelines connected to buildings Fracture and bridge deviation from piers, beam surface or pavement cracking, etc. The final settlement of building foundation under long-term load can be di...

AI Technical Summary

Problems solved by technology

[0006] After the foundation subsidence occurs, it is easy to have a great impact on the stability of the building, and there is a great potential safety hazard. However, for the building as a whole, the overall coverage of the building foundation is large, and it is difficult to find out in time after local settlement occurs. As a result, potential safety hazards cannot be eliminated or avoided in time, and the risk factor is high
