Description

Technical Field

[0001] The invention belongs to the technical field of soil protection, and in particular relates to rainfall sensing type two-component polymer grouting equipment and a manufacturing method thereof. Background Art

[0002] Landslides and mudslides are two very similar geological disaster phenomena, both of which are caused by heavy rain. Landslides are caused by heavy rain or torrential rain that overwhelms the mountain, causing the weak areas of the mountain to break and slide down as a whole; mudslides are caused by heavy rain or torrential rain that makes sand, soil, and stone saturated with water and liquefied. Under the action of gravity, the liquefied mud, sand, and stone flow to low-lying areas. In short, landslides and mudslides are closely related to the invasion of rainwater on the soil. At present, these two natural disasters occur frequently and are extremely destructive, causing serious loss of life and property. There are three main traditional methods to prevent landslides and mudslides:

[0003] (1) Use anchors, retaining walls, pile foundations and other retaining structures to strengthen the bearing capacity of the soil;

[0004] (2) Set up drainage ditches or drainage projects to prevent ground water from seeping into the soil, and take anti-seepage measures when necessary;

[0005] (3) Plant vegetation to consolidate the topsoil and reduce the probability and scale of debris flows and landslides.

[0006] No matter which method is used, it is impossible to adjust the slope protection in real time according to the amount of rainfall. In view of the inseparable relationship between these two natural disasters and precipitation, the traditional slope protection project may not be able to decide whether to carry out slope protection due to the uncertainty of precipitation, thus causing many accidents. Or there is a phenomenon that all slope protection projects have been completed for a slope, but there is no landslide and mud-rock flow, resulting in a lot of waste. In addition, the construction time of traditional slope protection projects is long and the cost is high. The present invention mainly aims at the shortcomings of the traditional slope protection method that it is impossible to adjust whether to carry out slope protection in real time according to the amount of rainfall, the construction period is long, and the cost is high. A rainfall sensing device is used. According to the amount of rainfall, the switch is triggered by the breakage of the steel wire to spray the two-component polymer material. The two-component polymer material expands rapidly to strengthen the soil and prevent rainwater from penetrating into the soil, effectively preventing the occurrence of landslides and mud-rock flows. At the same time, the manufacturing method of this device is simple, the price of materials such as polymers is low, the construction speed is fast and the cycle is short, and the advantages in technology and cost are significant. At present, the application of rain sensing devices or polymer materials in slope protection projects is not common, especially rain sensing trigger switches that do not rely on electricity are even rarer. Therefore, it is extremely necessary to make a rain sensing polymer grouting device that has both drainage function and soil reinforcement. Summary of the invention

The resin storage iron cylinder 31 is installed in the resin injection iron cylinder 28 in the same way as the curing agent storage iron cylinder 23 is installed in the curing agent injection iron cylinder 22, that is, the resin injector and the curing agent injector have the same structure and the same injection means, but the objects injected in the resin injector and the curing agent injector are different.
