A soil motion attitude monitoring box

Abstract

The invention discloses a soil movement attitude monitoring box, which comprises a hollow sphere, a sealing box, and an attitude angle sensor; The middle and lower part of the body is provided with an annular platform, and a cylindrical hollow cylinder is arranged on the annular platform. The top of the cylinder is connected with the sphere, and the bottom is connected with the inner ring edge of the annular platform. The outlet hole and the lower outlet hole are connected, and the cylinder is equipped with an internal thread-shaped wire setting table; the sealing box is fixed at the bottom of the ring platform, and the two attitude angle sensors are respectively fixed in the two sealing boxes to connect the power signal of the attitude angle sensor After the wire is drawn out from the sealed box, it is wound on the threaded wire-setting table in the cylinder and drawn out of the sphere through the upper outlet hole, and the power signal wire at the upper outlet hole is fixed on the upper outlet hole by water-soluble glue. The monitoring box is easy to operate, accurate in measurement, convenient in transportation and maintenance, and low in monitoring cost.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering monitoring, in particular to a soil movement attitude monitoring box. Background technique [0002] Deformation and displacement monitoring occupies an extremely important position in the quality and safety control of engineering construction. The existing space motion attitude monitoring technology is mostly applied to the structures above the ground, and cannot be applied to the deformation and displacement monitoring of the soil below the ground. However, excessive soil displacement and deformation are often the root causes of engineering accidents, such as foundation pit collapse, road surface subsidence, uneven foundation settlement, and slope instability. The difficulties in soil deformation and displacement monitoring are: 1. The monitoring box needs to move with the soil to truly reflect the displacement and deformation of the soil; 2. The monitoring box deployed in the s...

AI Technical Summary

Problems solved by technology

The difficulties in soil deformation and displacement monitoring are: 1. The monitoring box needs to move with the soil to truly reflect the displacement and deformation of the soil; 2. The monitoring box deployed in the soil needs external communication. The body shields the communication signal and consumes a lot of power. If the wired form is used, the cable will pull the monitoring box, causing the monitoring box to fail to reflect the real displacement and deformation of the soil; 3. The long-term existence of groundwater in the soil will not only affect The normal operation of the electronic monitoring equipment will also generate buoyancy to the monitoring box, making the monitoring results inaccurate; 4. It is difficult to deploy the monitoring box in deep soil, and the deployment depth is difficult to control

[0003] In the prior art, an inclinometer is used to monitor the displacement of the soil, but it can only monitor the horizontal displacement of the soil, and cannot fully monitor the overall movement posture of the soil; in addition, the inclinometer is generally used for manual data collection, and human factors Large impact, unable to automatically output, calculate, and analyze data in real time, high economic and labor costs
