Embodiment Construction

[0013] Such as figure 1 Shown: a kind of waste landfill HDPE film rain-sewage diversion drainage channel provided by the present invention comprises the anti-seepage layer laid on the surrounding slopes around the landfill 13, the landfill area, garbage dam 12, landfill The field reservoir area is divided into different blocks by ring-shaped anchoring platforms 6 at different levels; the area below the dam crest elevation is used as the leachate area 13, and the area above the dam crest elevation is used as the rainwater area 14. The area above the dam crest elevation is divided into different circular blocks according to different contour lines, and the landfill area is divided into two major blocks, the rainwater area 14 and the leachate area 13, based on the dam crest elevation of the garbage dam 12; the rainwater area 14 The annular anchoring platforms 6 with different elevations at all levels are separated into rainwater blocks of different elevations, and the rainwater a...

Abstract

The invention discloses an HDPE (High-Density PolyEthylene) membrane rain sewage diversion drainage canal for a refuse landfill. The HDPE membrane rain sewage diversion drainage canal for the refuse landfill comprises the refuse landfill, a seepage prevention layer laid on a slope around a field area of the refuse landfill and a retaining wall, wherein a reservoir area of the refuse landfill is divided into different blocks by each stage of annular anchoring platforms with different elevations; an area below the elevation of the top of the retaining wall is taken as a leachate area, and an area above the elevation of the top of the retaining wall is taken as a rain area; the rain area is divided into rain blocks with different elevations by each stage of anchoring platform with different elevations; HDPE membrane rain ridges are arranged on each stage of anchoring platform; an HDPE membrane rain sewage diversion drainage canal is formed between each HDPE membrane rain ridge and the sidewall of the higher stage of anchoring platform. According to the HDPE membrane rain sewage diversion drainage canal for the refuse landfill, the slope anchoring platforms are fully utilized, and the HDPE membrane rain sewage diversion drainage canals are constructed on each stage of anchoring platform, and are used for effectively intercepting rain in the blocks above the elevations of the HDPE membrane rain sewage diversion drainage canals and guiding and draining the rain out of the refuse landfill to fulfill the aim of rain sewage diversion; the HDPE membrane rain sewage diversion drainage canal for the refuse landfill has the advantages of simple structural form, convenience in construction and reliable effects.

Description

technical field [0001] The invention relates to a waste landfill, in particular to a waste landfill HDPE membrane rain and sewage diversion drainage channel. . Background technique [0002] The basic function of the landfill is to completely isolate the landfill from the surrounding stratum by laying an anti-seepage structure around the site, forming an independent and closed environment for the landfill, thereby preventing the leachate from seeping into the ground and affecting the landfill. Pollution of groundwater around the burial site. The source of leachate is the water generated by the decomposition of the garbage itself, the water content of the garbage, and the sewage generated by the infiltration of rainwater. The infiltration of rainwater is the main reason for the large amount of leachate. Correspondingly increased. If it is possible to design a rainwater and sewage diversion system for the landfill, the rainwater and leachate generated within the landfill are...
