[0001] The utility model relates to the technical field of soil environment restoration, in particular to a device for restoring the soil environment of an exposed geological slope. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. It uses physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or transform toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation can include: (1) changing the form of pollutants in the soil or the way they are combined with the soil, reducing their mobility and bioavailability in the environment; (2) reducing the concentration of harmful substances in the soil.

[0003] The exposed geology on the surface of the mining slope after resource exploitation is not suitable for vegetation to grow, but vegetation is very important for exposed land, so soilless fiber spraying technology has emerged. Soilless fiber spraying slope greening is one of the advanced slope greening ecological restoration technologies in China. Soilless fiber spraying is to use a certain amount of water, mixed plant seeds, organic fertilizers, water retaining agents, nutrient water retaining materials, anti-scouring binders and special environmentally friendly fiber covering materials as carriers, stir and mix to form a slurry mixture, and spray such a mixture evenly on the surface of the target area to be repaired according to the corresponding construction process requirements. After the spraying greening operation is completed, the slurry mixture will form a 2-5 cm interwoven layer of "vegetation greening blanket" on the soil surface. This "vegetation greening blanket" can not only adhere tightly to the surface of the slope, but also allow water to penetrate easily. It only takes two months to easily restore vegetation on the slope.

[0004] However, in the prior art, the slope surface is usually repaired by manually holding a spraying tube. However, the spraying tube is difficult to keep parallel to the slope, resulting in uneven spraying and poor slope vegetation restoration effect. Utility Model Content

After the adjustment is completed, the pin 16 is reinserted into the liquid outlet 14 corresponding to the fixed sleeve 401 under the action of the elastic potential energy of the second spring 15, and the operation is convenient and quick.
