Leachate diversion blind pipe laying system

Abstract

The invention discloses a pavement system for a percolate guide blind pipe. The system is that a layered multi-ring rectangular-ambulatory-plane type pavement structure is added on the basis of the single annular permeating preventing system at the bottom of the traditional refuse landfill; new guide blind pipes are added and fully distributed in different area according to the area of a filling unit, namely, the refuse in paving is piled into slopes by layers according to the standard level while upwards piling to form the slopes after one layer fills in the whole filling unit, the refuse is compacted, and a first circle of guide blind pipes is paved in all parts, except the bottom after reaching a certain of stage; the process includes the excavation of a blind gutter, pavement of stone in the blind gutter, and pavement of the pipeline; the pipeline is provided with a hole and wrapped with a geotechnical cloth. The system can solve the potential problem caused by paving single blind pipe at the bottom part in advance, such as blocking and breaking; in addition, the percolate collecting pressure can be greatly reduced, the percolate retaining time can be reduced, the filled refuse can be conveniently digested and settled, and therefore, the stability of piling bodies under the field filling work can be improved.

Description

technical field [0001] The invention relates to a garbage treatment system, in particular to a garbage leachate guiding and drainage system, which is applied in the technical field of environmental engineering. Background technique [0002] In the process of landfilling garbage, according to the design standard elevation, it is a gradual process of filling from bottom to top, layer by layer, compaction, and daily coverage. Every time the landfill operation is carried out, there will inevitably be digestion and settlement of the previous landfill garbage dump. With the improvement of living standards, the moisture content of domestic garbage in different regions varies from 35% to 75% in different seasons. % varies between. In this way, each layer must contain leachate from garbage digestion, and only relying on the leachate at the bottom of the landfill unit to guide the blind ditch cannot meet the demand for leachate removal, and with the passage of time, the leachate at t...
