A multi-sphere point detection method for foundation settlement

Abstract

The invention discloses a multi-ball point detection method for foundation settlement, which belongs to the field of foundation settlement detection. The ball is subjected to the sinking force, and the two self-separating hemispheres are separated from each other, so that the force of the two self-separating hemispheres acting on the pressure sensor is reduced. At this time, the pressure sensor transmits the signal to the cloud, and the cloud can roughly determine through cloud computing. Whether the foundation has subsided and the location of the subsidence, as the subsidence of the foundation gradually increases, the detection barbed wire is stretched and deformed, so that the tip of the embedded needle is exposed, and the fluorescent film ball is pierced, so that the fluorescent liquid flows out, and the settlement is determined When the site is being repaired, after excavation, the severity of the foundation settlement can be judged according to the fluorescence intensity generated near the multi-ball point pre-embedded pole, which is convenient for timely selection of appropriate maintenance measures and significantly reduces potential safety hazards.

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
