TECHNICAL FIELD

The present invention belongs to the technical field of soil protection, and particularly relates to a rainfall sensing two-component high-polymer grouting device and a manufacturing method therefor.

BACKGROUND ART

Landslides and mudslides are two very similar geological disasters, both of which are caused by heavy rains. Landslides are caused by heavy rains or continuous rainfall that overwhelm the mountain, disconnecting from weak areas of the mountain and causing the overall decline. Mudslides are caused by heavy rains or continuous rainfall that make the sands, soils, and rocks reaching the water-saturated state and reaching the liquefied state, so that under the action of gravity, the liquefied muds, sands, and rocks flow toward the low-lying places. All in all, landslides and mudslides are closely related to the invasion of soil by rains. At present, these two kinds of natural disasters occur frequently and have a great destructive power, causing serious losses of the lives and properties. There are mainly three traditional methods to prevent the landslides and mudslides:

(1) using supporting structures such as anchor rods, retaining walls, and pile foundations to reinforce the bearing capacity of the soil;

(2) setting up drainage ditches or drainage projects to prevent ground water from immersing into the soil, and taking the anti-seepage measures when necessary;

(3) planting the vegetation to consolidate the topsoil and reduce the probability and scale of the mudslides and landslides. No matter which method it is, it cannot be adjusted and adopted for slope protection in real time according to the amount of rainfall.

In view of the inseparable relationship between these two natural disasters and precipitation, traditional slope protection projects may not be able to decide whether to perform slope protection due to the uncertainty of precipitation, which causes many accidents. Or it may happen that all slope protection projects have been done for a slope body without landslides and mudslides, causing a lot of waste. In addition, the traditional slope protection projects have a long construction time and a high cost. The present invention mainly aims at the disadvantages that the traditional slope protection method cannot adjust whether to perform slope protection in real time according to the amount of rainfall, the construction period is long, and the cost is high. Using a rainfall sensing device, according to the amount of the rainfall, the switch is triggered by the break of the steel wire to spray (eject) the two-component high-polymer material. The rapid expansion of the two-component high-polymer material can strengthen the soil and prevent rainwater from penetrating into the soil, thereby effectively preventing the occurrence of the landslides and mudslides. Meanwhile, this device is of a simple manufacturing method, a low price of high-polymer and other materials, a fast construction speed with a short period, and has significant advantages in technology and cost. At present, the application of either the rainfall sensing device or the high-polymer material in slope protection projects is not common, especially the rainfall sensing trigger switch that does not need to rely on electricity is rare. Therefore, it is extremely necessary to make a rainfall sensing two-component high-polymer grouting device with both drainage function and soil reinforcement.
