Embodiment Construction
[0048] Examples see figure 1 As shown, this valley-type garbage landfill is connected in series with multi-section rain and sewage diversion devices, including the landfill area separated by the partition dam 3, and the HDPE anti-seepage film is laid on the surface of the partition dam 3, and it is connected with the HDPE anti-seepage membrane laid on the landfill area. The seepage membrane is welded into a whole, and there is a garbage dam 10 downstream of the landfill area, and a leachate sewage regulating pool 6 and a valve well 7 are arranged outside the garbage dam. There are thirteen separate landfill areas from upstream to downstream, each landfill The area is connected in series by the same blind ditch 1 for leachate drainage. There are perforated HDPE seepage guide pipes 2 in the leachate guide drain blind ditch. A pre-embedded casing 18 is set across the partition dam 3, and a valve I4 is installed on the HDPE seepage guide pipe 2 downstream of each partition dam 3,...
