Anti-seepage water storage blanket for sandy soil planting and preparation method of blanket

Abstract

The invention relates to an anti-seepage water storage blanket for sandy soil planting and a preparation method of the blanket. The anti-seepage water storage blanket is composed of an anti-seepage water storage layer and surface film layers arranged on the upper surface and the lower surface of the anti-seepage water storage layer; each surface film layer is made of breathable fabric film cloth,and the thickness of the anti-seepage water storage layer is 0.5-2 cm; the anti-seepage water storage layer is prepared from a mixture formed by mixing super-hydrophobic particles and a degradable flexible adhesive. Compared with the prior art, the problems that in the ecological planting process in a drought area, an anti-seepage material is difficult to construct, paving is uneven, an anti-seepage water storage layer is easy to damage, and water is likely to leak are solved. The anti-seepage water storage blanket remarkably improves the stability of the anti-seepage water storage layer, water leakage can be effectively prevented, the construction process is simple, and the anti-seepage water storage blanket has very wide application prospects.

Description

technical field [0001] The invention relates to the technical field of anti-seepage materials, in particular to an anti-seepage water storage blanket used for planting in sandy soil and a preparation method thereof. Background technique [0002] Desertification has become the most serious ecological environment problem in our country, which seriously hinders the construction of ecological civilization in our country. The difficulty of desert afforestation lies in: the sandy soil in the desert is loose, water is easy to lose, there is no nutrient in the soil, plants cannot obtain sufficient water and nutrition, and it is difficult to survive. As a result, the vegetation coverage rate is decreasing day by day, and the land is degraded. Therefore, effectively preventing water leakage, increasing vegetation coverage, and restoring and rebuilding damaged ecosystems have become a major and urgent development topic in the construction of ecological civilization. [0003] Because ...

AI Technical Summary

Problems solved by technology

However, at present, the anti-seepage material is only a thin layer on the sandy soil surface, and the construction process is manual paving, so it is difficult to ensure the uniformity of paving

In addition, due to the strong wind and sand in the desert area, the anti-seepage material is easily blown away, which may easily lead to partial leakage of the anti-seepage material, which in turn leads to water seepage.

[0004] In order to solve the problem that anti-seepage materials are difficult to construct, patent CN103755303A discloses a sand-based planting trough, which is a trough-shaped container surrounded by a plurality of air-permeable and anti-seepage sand plates. Fat and other advantages

However, its production process is complex, and during construction, pits need to be dug in sandy soil areas, and then sand-based planting troughs are placed in them. The operation is cumbersome and it is not suitable for large-scale construction.
