Problems solved by technology
[0003] The invention aims to overcome the problem that the anti-seepage liner and anti-seepage wall of the existing landfill cannot be self-repaired and blocked the acid leachate of the new landfill due to micro-crack leakage, and overcome the anti-seepage caused by the large deformation caused by the earthquake. Seepage liner and anti-seepage wall stagger large cracks to cause acid leachate pollution, the invention provides a self-repairing landfill anti-seepage layer

Embodiment Construction
[0027] In order to make the technical means, innovative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0028] Such as Figure 1-6 A kind of self-repairing anti-seepage layer of landfill, including several self-repairing bars 1, anti-seepage base 2; the self-repairing bars 1 are distributed in the anti-seepage base 2; the self-repairing bars 1 include several intelligent Drive the switch 3, the concentric first hollow rod 4 and the second hollow rod 5, the second hollow rod 5 is located inside the first hollow rod 4, the space between the first hollow rod 4 and the second hollow rod 5 is full of repair Solution 6, the inside of the second hollow rod 5 is filled with liquid 7 that stimulates the solidification of the repair solution, and the intelligent drive switch 3 is located on the opening 15 of the side wall of the first hollow rod 4 and can...

The invention discloses a self-repairing garbage landfill impervious layer and a self-repairing impervious method thereof. The self-repairing garbage landfill impervious layer comprises a plurality ofself-repairing rods and an impervious base layer. The self-repairing rods are distributed in the impervious base layer. Each self-repairing rod comprises a plurality of intelligent drive switches, afirst hollow rod and a second hollow rod, wherein the first hollow rod and the second hollow rod are concentric, the second hollow rod is located in the first hollow rod, space for spacing the first hollow rod and the second hollow rod is filled with a repairing solution, the second hollow rod is filled with liquid for motivating the repairing solution to be solidified, and the intelligent drive switch is located on the side wall of the first hollow rod. When the intelligent drive switch meets leachate in the garbage landfill, due to the change of the PH value, the intelligent drive switch will be turned on, and thus the repairing solution flows out of the first hollow rods. The self-repairing garbage landfill impervious layer can block leakage, caused by micro cracks, of the leachate of new garbage landfill, and can also block dislocation large cracks, caused by large deformation of earthquakes, of the impervious layer, and thus leachate pollution 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 a 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. The frequency of wat...
