Device and method for measuring soil body displacement

Abstract

The invention relates to a device and a method for measuring soil body displacement. The device comprises a sedimentation pipe or an inclinometer pipe, a magnet ring locating sensor and a data acquisition device. The sedimentation pipe or the inclinometer pipe is embedded in the soil body. The magnet ring locating sensor is parallelly arranged inside the sedimentation pipe or the inclinometer pipe and covers displacement changing range of a magnet ring in the whole journey, serves as a measuring basis, is constant in fixed position and comprises a plurality of magnetic sensitive elements, a strip-shaped support piece and a detection circuit. The device and the method can achieve automatic intelligent measurement of soil body displacement, are suitable for measurement of relative displacement of the soil body in one direction, and have the advantages of being simple in use and good in measuring reliability.

Description

technical field [0001] The invention relates to the technical field of geotechnical safety monitoring, in particular to a soil displacement measuring device and method, which is suitable for measuring internal or external displacement of soil, such as earth dams, earth-rock dams, rockfill dams, side slopes and backfill soils The settlement displacement measurement of , or the horizontal displacement measurement of the above soil. Background technique [0002] At present, there are several kinds of soil displacement measuring devices at home and abroad, such as water tube settlement meter, fixed inclinometer, pressure sensor, static level and so on. These devices all have some technical defects, some can realize automatic monitoring but The reliability of the measurement is poor or prone to failures and requires frequent maintenance. Some of them have good reliability but cannot achieve continuous automatic measurement or remote telemetry, or are limited by tedious constructi...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the problem that the existing soil displacement measurement device has poor reliability and is prone to failure or that continuous automatic measurement or remote telemetry cannot be realized although the reliability is good, and a novel soil displacement measurement device is provided. The measuring device can realize automatic and intelligent measurement of soil displacement, and is suitable for relative displacement measurement of soil in a certain direction. It has the advantages of simple structure and good measurement reliability.
