Problems solved by technology

Landfills that lack strict anti-seepage and drainage measures will be a huge source of pollution. The leachate produced will pollute the groundwater, and the landfill gas will pollute the air.
At present, most landfills lack effective drainage measures, and the accumulation of a large amount of leachate and landfill gas in the landfill will also cause problems such as unstable landslides, landfill gas explosions, and fires in the garbage dump; large-scale mechanical operations on the upper part The settlement of garbage dumps can easily lead to distortion, deformation or even damage of ordinary drainage pipes, and it is difficult to repair and replace; the later construction of drainage systems often uses drilling construction, which is cumbersome and requires a large amount of work. The drainage effect is not good, and it is easy to cause filling Buried gas leakage pollutes the environment
[0003] In order to solve the problem of leachate accumulation and leakage and reduce the risk of landfill gas leakage, the present invention provides an assembled vertical and horizontal drainage system for landfills and its construction method, which can control the main water level of leachate in landfills for a long time , Improve the collection rate of landfill gas and the stability of the slope of the garbage dump

Abstract

The invention discloses an assembled vertical and horizontal guide and drainage system for a waste landfill and a construction method thereof. The prefabricated vertical and horizontal guide system for the landfill is composed of a liner structure, a warehouse body guide structure and a vertical and horizontal guide system. The liner structure includes a rammed clay bottom layer, a geomembrane, a rammed clay surface layer, and a sprayed UHPC anti-seepage layer; The guide drainage structure of the warehouse body includes UHPC collection well, steel grid manhole cover, circular pipe opening, geotechnical composite drainage network of the warehouse body, washed gravel layer of the warehouse body, and clay sealing layer; the vertical and horizontal guide drainage system includes UHPC core drainage pipe, UHPC longitudinal guide pipe, UHPC horizontal guide pipe, submersible sewage pump, lifting rope and drainage hose. The invention adopts prefabricated construction, has short construction period, reliable and durable structure, can control the main water level of leachate for a long time, and has the advantages of good guide and drainage effect, long life cycle and low maintenance cost.

Description

technical field [0001] The invention relates to the technical field of waste landfill guiding and drainage, in particular to an assembled vertical and horizontal guiding system for garbage landfills and a construction method thereof. Background technique [0002] Landfill is an important method to deal with municipal solid waste. Landfills that lack strict anti-seepage and drainage measures will be a huge source of pollution. The leachate produced will pollute the groundwater, and the landfill gas will pollute the air. At present, most landfills lack effective drainage measures, and the accumulation of a large amount of leachate and landfill gas in the landfill will also cause problems such as unstable landslides, landfill gas explosions, and fires in the garbage dump; large-scale mechanical operations on the upper part The settlement of garbage dumps can easily lead to distortion, deformation or even damage of ordinary drainage pipes, and it is difficult to repair and repl...
