A mountain collapse monitoring and early warning device

Abstract

The invention discloses a mountain collapse monitoring and early warning device, which comprises a fixed side fixed detection box, and the middle position of the fixed side fixed detection box close to the side of the collapse crack is fixedly connected with an outer fixed detection box through a mechanical telescopic outer tube. The interior of the mechanical telescopic outer tube is provided with a plastic elastic hollow tube, and the fixed side fixed detection box and the outer fixed detection box are both located below the ground, and the fixed side fixed detection box is close to the inner side of the outer fixed detection box The bottom end is fixedly connected with an adjustment control box, and the inside of the adjustment control box is provided with a signal transmitter receiver, a data comparator and a central processing unit. The invention relates to the field of natural geological disaster protection and early warning equipment. The mountain collapse monitoring and early warning device has a high degree of automation and low cost. It is located below the ground and occupies a small space. It can automatically and accurately detect the expansion of the width of mountain cracks, and enhance the timeliness and accuracy of monitoring.

Description

technical field [0001] The invention relates to the field of natural geological disaster protection and early warning equipment, in particular to a mountain collapse monitoring and early warning device. Background technique [0002] Geological hazards, a professional term in geology, refer to geological effects (phenomena) that are formed under the action of natural or human factors and cause damage and loss to human life, property and the environment. Such as collapse, landslide, debris flow, ground fissure, soil erosion, land desertification and swamp, soil salinization, and earthquake, volcano, geothermal damage, etc. The precursors of the collapse are: the front edge of the collapse continues to lose blocks, fall, and small collapses; new cracks appear at the foot of the collapse; the sound of tearing and rubbing rocks is heard occasionally; abnormalities of heat, air, and groundwater appear. ; Transverse and longitudinal cracks appear at the front edge of the landslide...

AI Technical Summary

Problems solved by technology

The precursors of the collapse are: the front edge of the collapse continues to lose blocks, fall, and small collapses; new cracks appear at the foot of the collapse; the sound of tearing and rubbing rocks is heard occasionally; abnormalities of heat, air, and groundwater appear. ; Transverse and longitudinal cracks appear at the front edge of the landslide, and uplifts appear in the soil mass at the front edge; cracks widen and lengthen sharply at the trailing edge of the landslide mass, new cracks are continuously generated, the rear part of the landslide mass is quickly subsided, and the surrounding rock and soil mass is loosened and small-scale collapsed Sliding phenomenon; simple monitoring of geological disasters refers to the monitoring method of monitoring the displacement changes of disaster bodies, houses or structures with the help of simple measuring tools, instruments and measuring methods. At present, the early warning of landslides and collapses mostly uses artificial timing measurement method, the degree of automation is low, and the early warning time node is difficult to accurately grasp
