Isolation anchoring structure between adjacent garbage piles

Abstract

The invention discloses an isolation anchoring structure between adjacent garbage piles. By the technical scheme, an anchoring groove is formed in the garbage pile, the garbage pile is isolated and divided into a unit A garbage block and a unit B garbage block through the anchoring groove, wherein a unit A HDPE covering film laid on the surface of the unit A garbage block extends into the anchoring groove and is leveled through garbage to form the anchoring structure, a unit B HDPE covering film laid on the surface of the unit B garbage block extends to and laid on the surface of the backfilling garbage and is subjected to hot melting welding with the unit A HDPE covering film into a whole. According to the isolation anchoring structure, through improving a membrane sealing connection technology, the flow of biogas under the membrane between the garbage pile of adjacent units can be effectively blocked, and the defect of splitting of rain and dirt is avoided, and water leakage and airleakage accidents are prevented even if the covering film in the anchoring groove is damaged due to natural sedimentation of the garbage pile.

Description

technical field [0001] The invention relates to the technical field of landfill technology for solid waste landfills, in particular to an isolation anchoring structure between adjacent garbage piles. Background technique [0002] To ensure the safety and stability of the garbage dump in the landfill site, prevent the risk of instability of the garbage dump, and ensure the safety, the efficient use of land resources and the maximization of the landfill storage capacity require systematic planning and scientific planning of the landfill operation. manage. Cleaning and diverting sewage, reducing the infiltration of rainwater, reducing the amount of leachate produced, maximizing the collection of landfill gas, reducing the overflow of landfill gas, and reducing odor are several key links in the work of improving environmental quality. The landfill process of the waste landfill in the reservoir area implements landfill operations in divisions and units, and anchors each garbage ...

AI Technical Summary

Problems solved by technology

However, the membrane sealing process in the isolation and anchoring structure of the prior art does not have a good effect of blocking the circulation of biogas. After the covering film in the anchoring ditch caused by the natural settlement of the garbage dump is damaged, water leakage and air leakage will be caused, and the entire landfill reservoir area will be damaged. The biogas leaking from the damaged place not only destroys the surrounding ecological environment, affects the living environment of the surrounding residents, but also produces secondary pollution, which is easy to cause combustion and explosion accidents
