Anti-landslide early warning device and using method thereof

Abstract

The invention discloses an anti-landslide early warning device and a using method thereof, belongs to the field of disaster early warning, and aims at dissolving hydrosol on a support frame by utilizing water in soil, enabling the water to permeate into an embedded pipe to be discharged to the outside through a generated gap and playing a certain role in preventing landslide. Before landslide occurs, soil moves downwards to extrude the air bag, inert gas in the air bag is transferred, the inert gas enables the separation membrane to expand, the separation membrane is punctured through the puncture needle to release the dyeing pigment, the dyeing pigment and rainwater are mixed and then washed out of the embedded pipe by the rainwater, and an alarm is transmitted to the outside. Precious escape time is reserved for people below to reduce life and property loss, and the larger the downward movement amount of soil is, the different separation membranes can be broken, so that pigments withdifferent colors or different chromaticity are released, grades are distinguished for early warning signals, corresponding countermeasures can be taken conveniently, and the safety of people and properties is further protected.

Description

technical field [0001] The invention relates to the field of disaster early warning, more specifically, to an anti-landslide early warning device and a method for using the same. Background technique [0002] Landslide refers to the soil or rock mass on the slope, affected by factors such as river scouring, groundwater activity, rainwater immersion, earthquake and artificial slope cutting, under the action of gravity, along a certain weak surface or weak zone, the whole or scattered The natural phenomenon of land sliding downhill. The moving rock (soil) body is called displacement body or sliding body, and the underlying rock (soil) body that has not moved is called sliding bed. [0003] The most important reason for landslides is that a large amount of water accumulates in the soil, and the shear force of the soil becomes smaller because it cannot be discharged in time, which eventually leads to the occurrence of landslides. At present, the main way to prevent landslides i...

[0003] The most important reason for landslides is that a large amount of water accumulates in the soil, and the shear force of the soil becomes smaller because it cannot be discharged in time, which eventually leads to the occurrence of landslides. At present, the main way to prevent landslides is to install protective nets or build protective structure, but the effect of the protective net is not very great. It is generally used in places with falling rocks, and the engineering volume of the protective structure is too large. Although it can prevent the occurrence of landslides to a certain extent, the occurrence of landslides is instantaneous. However, it is not possible to give an early warning before the landslide occurs, and it is impossible to leave enough time for the people and property below to transfer, and its function is too single
