Mining area rock-soil layer disintegration and landslide early warning system

Abstract

The invention relates to a landslide early warning system, in particular to a mining area rock-soil layer disintegration and landslide early warning system, which comprises detection piles and pull rods. The pull rods are used for connecting all the detection piles; each detection pile comprises a plurality of detection modules, a hammering pull head and a conical head; and the detection modules are sequentially connected in the vertical direction. Each detection module is provided with a sliding block, a sliding closing plate, a mass block, a pore pressure sensor, a strain gauge type pressuresensor and a follow-up rod. When landslide occurs in a certain layer, the corresponding detection module is pushed to move, the sliding block pushes the follow-up rod on a sliding sealing plate to move, that is, a sliding deviation piece can move, and under the self-stabilization effect of the mass block, the sliding deviation piece and the follow-up rod can move in the direction opposite to thedisplacement direction of the detection module, a strain gauge type pressure sensor is attached to the side face of the follow-up rod, and an alarm is given for sudden increase of the numerical valueof the pore pressure sensor and the numerical value of the strain gauge type pressure sensor.

Description

technical field [0001] The invention relates to a landslide early warning system, in particular to a landslide early warning system for rock and soil layer disintegration in a mining area. Background technique [0002] The methods of landslide displacement monitoring mainly include manual monitoring, instrument monitoring and remote automatic monitoring. The workload of manual monitoring is large, and there are large human measurement errors; instrument monitoring can measure the displacement of landslides more accurately, but most of them require special monitoring equipment, and the operation has certain difficulties. The existing landslide displacement monitoring system can refer to CN110940305A The Chinese patent document of , discloses a landslide displacement monitoring system, including a measuring device, a motor, a wireless data transmitting device, a data receiving terminal, and an alarm module. The measuring device includes a fixed rod, an accommodation box, a mo...
