Abstract

The invention relates to the technical field of ecological environment restoration, in particular to a breathable and impermeable blanket and a production process thereof. The breathable and impermeable blanket comprises an upper breathable layer, a lower breathable layer and a breathable and impermeable sand layer sandwiched therebetween, wherein the breathable and impermeable sand layer comprises breathable and impermeable particles and expansive particles. The breathable and impermeable blanket disclosed by the invention is convenient to construct, high in production efficiency and dustfreein the construction process.

Description

technical field [0001] The invention relates to the technical field of ecological environment restoration, in particular to a breathable anti-seepage blanket and a production process thereof. Background technique [0002] my country's water resources are particularly scarce, with a total volume of 28 trillion cubic meters and a per capita water resource of only 2,170 cubic meters, which is less than a quarter of the world's average level. It is one of the 13 water-poor countries in the world. In my country, available water sources mainly include river water, freshwater lake water and shallow groundwater. For surface freshwater resources such as rivers and lakes, water loss is mainly due to evaporation and seepage. According to incomplete statistics, seepage accounts for about 80% of water loss. [0003] In the prior art, in order to solve the leakage of surface fresh water resources such as lakes, an anti-seepage layer is mainly used. The anti-seepage layer is a structural ...
