A kind of anti-landslide early warning device and using method thereof

Abstract

The invention discloses an anti-landslide early warning device and its application method, which belong to the field of disaster early warning. It uses water in the soil to dissolve the hydrosol on the support frame, and the resulting gap allows water to penetrate into the pre-embedded pipe It is discharged to the outside and plays a certain role in preventing the occurrence of landslides. The air bag is squeezed by the downward movement of the soil before the landslide occurs, so that the inert gas in the air bag is transferred, and the inert gas expands the separation membrane. Piercing to release the dyeing pigment, the dyeing pigment is mixed with rainwater and washed out of the embedded pipe by rainwater to send a warning to the outside world, leaving valuable escape time for the people below, so as to reduce the loss of life and property, and the soil The greater the downward movement, the different separation membranes can be broken, thereby releasing pigments of different colors or different shades, so as to distinguish the levels of early warning signals, so that corresponding countermeasures can be taken, and the safety of people and property can be 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...

Problems solved by technology

[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
