Abstract

The invention relates to the technical field of ecological environment restoration and in particular relates to an air-permeable and seepage-proof carpet and a production technology thereof. The air-permeable and seepage-proof carpet provided by the invention comprises an upper air-permeable layer, a lower air-permeable layer and an air-permeable and seepage-proof sand layer clamped between the upper air-permeable layer and the lower air-permeable layer; the air-permeable and seepage-proof sand layer is prepared from the following raw materials: sand, a hydrophobic material and expanding particles. The air-permeable and seepage-proof carpet provided by the invention has the advantages of convenience for construction, high production efficiency and no dust in a 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 ...
