Under the influence of weather, if strong wind and rainwater weather appear, the soil piled on the ground and excavated can be blown away by strong wind and taken away by rainwater, so that the soil is lost, and the environment around construction is influenced.
In order to reduce the influence of the stacked soil on the environment, a construction method generally covers a layer of black mesh on the soil. The black mesh cloth can prevent the sun from directly irradiating on the soil on one hand, and can also prevent the soil from being blown away along with wind to form dust pollution on the other hand; in addition, under the effect of black screen cloth, can reduce earth to a certain extent and run off along with the rainwater.
However, the mesh of the black mesh cloth is large, the mesh line thickness of the mesh cloth is small, and the black mesh cloth has a weak soil fixing effect on stacked soil. Under the action of rainwater, some soil still flows away along with the rainwater in the stacked soil, so that the soil is difficult to clean and pollutes the environment.
