Abstract

The invention discloses a landfill liquid guide and drainage system. The landfill liquid guide and drainage system comprises a diversion blind groove and a guide and drainage device installed in the diversion blind groove. The guide and drainage device is composed of a floral tube and an outer wrapping layer. A plurality of filter holes are formed in the floral tube. A cushion layer is arranged on the outer surface of the floral tube and is distributed in the axis direction of the floral tube. Grooves are formed in the outer surface of the cushion layer. The filter holes are distributed in the circumferential direction of the floral tube in four sets. The circle center angle of the portion, corresponding to the area where each set of filter holes are located, of the floral tube is 45 degrees. The cushion layer is located on the area, not occupied by the filter holes, of the outer side of the floral tube, wherein the corresponding circle center angle is 45 degrees. The cushion layer is arranged between the floral tube and the wrapping layer, and therefore the space between the floral tube and the wrapping layer is enlarged, and the liquid guide and drainage efficiency between the floral tube and the wrapping layer is improved; the grooves are formed, the contact area between the cushion layer and the wrapping layer is narrowed, and by means of the design, harmful liquid infiltrating the contact area of the cushion layer and the wrapping layer can be smoothly collected and converged into the guide and drainage floral tube.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to a landfill liquid guiding system. Background technique [0002] At present, the leachate or groundwater in the solid waste treatment landfill is mainly collected and guided out of the landfill reservoir area through the liquid drainage system pre-buried at the bottom of the solid waste landfill. The liquid drainage system mainly includes the blind ditch and the open-hole flower tube arranged in the blind ditch. The flower tube is wrapped with non-woven geotextile, and gravel is filled in the flower tube wrapped in geotextile and the blind ditch to form a complete liquid collection and drainage system. system. Due to the large contact area between the geotextile and the flower tube in the existing drainage pipe, with long-term use, solid waste or fine particles in the soil layer will gradually accumulate, causing the drainage system to be easily blocked,...
