A monitoring device suitable for soil layer settlement in geotechnical engineering construction

Abstract

A monitoring device suitable for soil layer settlement in geotechnical engineering construction, comprising an annular fixing seat, the annular fixing seat is connected to a protection tube, the protection tube is connected to an annular plate, the annular plate is connected to a screw rod, and the screw rod is connected to a first telescopic shaft and a thin shaft, The first telescopic shaft is connected to the annular fixed seat, the first telescopic shaft is connected to the first displacement sensor, the first displacement sensor is fixedly connected to the annular plate, the thin shaft is connected to the second displacement sensor, and a magnet is installed on the second displacement sensor; Internally threaded pipe, a bar-shaped chute is provided outside the internally threaded pipe, a slide bar is installed in the bar-shaped chute, a first helical gear is installed at the inner end of the externally threaded pipe, and a second helical gear is installed outside the thin shaft. The present invention is simple in structure, ingenious in conception, convenient in use and operation, can respectively fix and connect each part of the settlement detection device with the buried hole through the fixing device, and can fix and install the settlement device on the buried hole in sections, thereby improving the accuracy of the settlement monitoring data performance to meet market demand.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering monitoring, in particular to a monitoring device suitable for soil layer settlement in geotechnical engineering construction. Background technique [0002] In filling roadbeds, embankments, airports and urban construction land leveling projects, internal layered settlement monitoring is an important part of geotechnical engineering [0003] The main content of monitoring. The settlement monitoring data during the construction period and the post-construction period of the filling are instructive to control the construction rate, ensure the construction quality and optimize the design parameters; the layered settlement monitoring only relies on the friction between the inner wall of the buried hole and the detection device, The error in detecting the settlement is relatively large, or the detection device is pre-buried in layers by digging pits, the construction operation is complicated, th...

Problems solved by technology

The settlement monitoring data during the construction period and the post-construction period of the filling are instructive to control the construction rate, ensure the construction quality and optimize the design parameters; the layered settlement monitoring only relies on the friction between the inner wall of the buried hole and the detection device, The error in detecting the settlement is large, or the detection device is pre-buried in layers by digging pits, the construction operation is complicated, the efficiency is low, and it is difficult to meet the actual needs. Therefore, we have invented a monitoring device suitable for soil layer settlement in geotechnical engineering construction.
