System for shunting rainwater and sewage in reservoir area above crest elevation of valley type refuse landfill
A system for shunting rainwater and sewage in a reservoir area above the crest elevation of a valley type refuse landfill comprises a refuse landfill area, a reservoir area foundation, a reservoir area side slope, an anchoring platform arranged on the reservoir area side slope and an anchoring ditch formed in the anchoring platform. The reservoir area foundation is covered with an impermeable layer, a leachate guiding and discharging pipe is laid on the impermeable layer, a zoned dam is arranged on the impermeable layer in a downstream area and the leachate guiding and discharging pipe, the refuse landfill area is arranged in the downstream area of the zoned dam, a side slope drainage channel is arranged in the anchoring ditch of the anchoring platform on the reservoir area side slope located in the upstream area of the zoned dam, the leachate guiding and discharging pipe located under the zoned dam is a solid pipe, the leachate guiding and discharging pipe located at the upstream area of the refuse landfill area and the zoned dam is a floral pipe, and a valve is arranged at the position where the solid pipe at the position of the upstream slope toe of the zoned dam is connected with the floral pipe at the high position of the solid pipe. The problem that rainwater and sewage of the reservoir area in the partial region where the reservoir bottom elevation of the refuse landfill is higher than the crest elevation of a refuse dam cannot be shunted and accordingly all rainwater permeates into a refuse dump body to be converted into leachate is solved, and the system is simple in structure and reliable in effect.
