Description

Soil body subsides monitoring devices of subsidence magnetic ring is arranged to accuracy

Technical Field

The utility model relates to the field of soft soil foundation settlement monitoring, in particular to a soil settlement monitoring device with accurately arranged settlement magnetic rings.

Background

The soft soil stratum has the characteristics of high water content, high pore ratio, high compressibility, low permeability, low strength and the like, and is extremely easy to generate consolidation settlement or bulge under the action of upper load or disturbance of underground building construction, so that the prediction and control of soil layer settlement and bulge in engineering are always a key problem.

The layered settlement monitoring of soil mass is a common method for measuring the settlement or uplift values of soil mass with different depths under the ground by a layered settlement meter, the layered settlement meter generally comprises a magnetic probe, a scale with scales and an inductance detection device which are matched with a settlement magnetic ring and an inclinometer or a water level pipe for use together, and the operation principle is that the settlement magnetic ring with magnetic force is sleeved on a PVC pipe and buried together to a preset depth in a drilling mode, and the position of the settlement magnetic ring with magnetic force is detected by the magnetic probe to determine the settlement value.

The construction method of the sedimentation magnetic ring in the existing soil body layered sedimentation monitoring is that holes are drilled in advance, and then spring pieces for bundling the sedimentation magnetic ring are connected to a PVC pipe and pressed into the pre-drilled holes to be buried in a soil layer. The conventional method for embedding the sedimentation magnetic ring has the defects that the sedimentation magnetic ring is difficult to fix on a soil layer with a preset depth, and the main reason for the defects is that the sedimentation magnetic ring moves up and down due to the friction action of the hole wall, and a spring iron sheet is opened before the sedimentation magnetic ring reaches the preset depth, so that a certain error occurs between an actual sedimentation monitoring position and a design position. The actual field discovers that the error can reach 1-1.5 m, which generates great error for monitoring the deep displacement condition of the appointed soil layer and can not meet the requirement of primary design.
