Guide-wheel-free clinometer used for measuring displacement of deep part of landslide, and installation method thereof

Abstract

The invention discloses a guide-wheel-free clinometer used for measuring displacement of a deep part of a landslide, and an installation method thereof. The guide-wheel-free clinometers comprises a PVC pipe, a monitor case disposed above the pipe opening of the PVC pipe, and a plurality of detection nodes arranged in the PVC pipe. Every two adjacent detection nodes are connected to a bellows through a cable. Each detection node includes a main probe and four auxiliary probes. The main probe and the four auxiliary probes are sequentially connected in series through cables. The main probe and the adjacent auxiliary probes are connected through bellows, and every two adjacent auxiliary probes are connected through a bellows. A data acquisition module, a data transmission module and a power supply module are arranged in the monitor case. The data acquisition module is used for acquiring data of the main probe. The data transmission module is used for transmitting the data acquired by the data acquisition module to a remote data server center by means of a GPRS transmission network. The power supply module provides power for the data acquisition module and the data transmission module. On-site installation construction is convenient, the measurement is accurate, and automatic measuring and real-time dynamic monitoring can be achieved.

Description

technical field [0001] The invention relates to the field of landslide inclinometers, in particular to a guide wheel-less inclinometer used for deep displacement measurement of landslides and an installation method thereof. Background technique [0002] The deformation of the landslide starts at the interior (deep part) of the landslide body, and then gradually develops to the surface. The inclinometer (also known as the borehole inclinometer) is a very important monitoring instrument for the deep displacement of landslides and other geological disasters, so it is also called the internal observation instrument. The angle change between them can realize the deep horizontal displacement monitoring of the rock and soil mass, which can effectively judge the position of the landslide slide zone, understand the deep deformation of the landslide mass, and provide a basis for evaluating the stability of the landslide mass. [0003] In the field of geological disaster monitoring, t...
