Intelligent-driven self-healing anti-seepage layer of landfill and its self-healing anti-seepage method

Abstract

The invention discloses a landfill anti-leakage layer with an intelligence-driven self-repairing function and a self-repairing anti-leakage method thereof. The landfill anti-leakage layer includes multiple self-repairing rods and an anti-leakage base layer; the self-repairing rods are distributed in the anti-leakage base layer; each self-repairing rod includes multiple intelligent driving switches, a first hollow rod and a second hollow rod, each second hollow rod is positioned in the corresponding first hollow rod and is coaxial with the corresponding first hollow rod, the spacing between each first hollow rod and the corresponding second hollow rod is filled with a repairing solution, each second hollow rod is filled with liquid stimulating solidification of the repairing solution, and the intelligent driving switches are positioned on the side walls of the first hollow rods. The landfill anti-leakage layer and the self-repairing anti-leakage method can prevent leakage, caused by small cracks, of leachate of a new landfill and also can block up large cracks generated by diastrophism of the anti-leakage layer due to large deformation after an earthquake, and therefore pollution ofthe leachate is prevented.

Description

technical field [0001] The invention belongs to the field of environmental rock and soil in geotechnical engineering, and in particular relates to an intelligently driven self-repairing anti-seepage layer of garbage landfill. Background technique [0002] With the expansion of city scale, how to deal with more and more domestic waste has become a very important task. Construction of landfills is widely used in the country. "Control Standards for Domestic Waste Landfill Sites" GB 16889-2008 stipulates special discharge limits for water pollutants in landfill sites, such as chemical oxygen demand, biochemical oxygen demand and heavy metal content limits, etc., and also points out that pollutants need to be installed Emission automatic monitoring equipment. The frequency and sampling time of pollutant discharge monitoring in domestic waste landfills need to be carried out according to the specifications. In addition, monitoring wells are required to monitor groundwater quality...

AI Technical Summary

Problems solved by technology

[0003] The invention aims to overcome the problem that the anti-seepage lining and anti-seepage wall of the existing landfill cannot be self-repaired and blocked the acid leachate of the new landfill due to crack leakage, and overcome the large deformation of the anti-seepage lining caused by the earthquake. Layer and anti-seepage wall stagger large cracks to cause acid leachate pollution, the invention provides an intelligently driven self-repairing landfill anti-seepage layer
