Abstract

The invention discloses an anti-seepage composite barrier, which comprises an anti-bypass seepage part and an anti-seepage layer, wherein the anti-bypass seepage part comprises a water soluble polymer membrane and expansive clay, the expansive clay is packaged in the water soluble polymer membrane, a groove is formed in the surface of the anti-bypass seepage part, and the bottom part of the anti-seepage layer is embedded in the groove of the anti-bypass seepage part. The anti-seepage composite barrier has the advantages that the construction is simple, the anti-seepage effect is good, and the problem of bypass seepage at the connecting part of a HDPE (high-density polyethylene) geomembrane and an underground impervious layer is solved.

Description

technical field [0001] The invention belongs to the technical field of pollutant control and ecological environment restoration, and in particular relates to an anti-leakage composite barrier for ecological environment restoration. Background technique [0002] With the rapid development of industrialization in our country, the damage to the environment is also becoming more and more serious. In particular, some chemical and mining companies have not taken anti-seepage measures for the existing solid waste dumps, mine heap leaching sites, tailings ponds, etc., causing toxic and harmful substances to endanger the ecological environment through various channels, pollute the soil and groundwater, and seriously Affect people's normal life and health. [0003] With the advancement of technology, the anti-seepage problem of storage yards and tailing ponds of chemical and mining enterprises has been effectively solved. Some vertical anti-seepage technologies, such as grouting cur...
