Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention will be further described: as figure 1 As shown, trenches are excavated at the top of the slope or at the middle platform, and prefabricated concrete anchor piles are driven into the bottom of the trenches, and then the rice husk ash concrete anchor shells are fixed to the concrete anchor piles through expansion bolts and rubber gaskets. upper end. Backfill the grooves on both sides of the anchorage shell to the level of the top surface. Fold the lower geotextile, anti-seepage geomembrane and upper geotextile of the liner material in the anchor shell of rice husk ash concrete in turn, then place the upper perforated PVC pipe in the lower part of the anchor shell, and pour rice husk ash concrete around it to fill After the health preservation is qualified, the upper part is filled with gravel.

[0026] Such as figure 2 As shown, the anchor shell is made of rice husk ash concrete material, which has...

Abstract

The invention relates to a landfill liner layer anchoring structure using rice hull ash concrete and belongs to the technical field of environmental protection. A lining layer is arranged on the sideslope of the a landfill, the lining layer specifically comprises a middle anti-seepage film and geotextile on two sides, a rice husk ash concrete anchoring shell is arranged at the top end or the middle platform of the side slope and is fixed in an anchoring groove through a precast concrete pile, the lining layer is folded in the rice hull ash concrete anchoring shell, an upper perforated PVC pipe is arranged at the lower part in the anchoring shell, the rice hull ash concrete filler is poured at the periphery, and the upper part is filled with crushed stones. The anchoring structure adopts partial prefabricated construction, a part of parts can be manufactured in a standardized way, and the anchoring structure has the function of collecting, guiding and draining percolate.

Description

technical field [0001] The invention relates to an anchoring structure for a liner layer of an urban garbage sanitary landfill site, and belongs to the technical field of environmental protection. Background technique [0002] With the development of the national economy and the improvement of the level of urbanization, the amount of municipal solid waste is increasing sharply. There are three main final disposal methods for municipal solid waste: sanitary landfill, composting and incineration. Among them, sanitary landfill is the most commonly used waste disposal technology in the world. On the basis of scientific site selection, it adopts necessary site protection treatment methods and reasonable landfill structure to minimize and eliminate the impact of garbage on the environment, especially on groundwater pollution. In recent years, many cities have successively built large domestic waste landfills. [0003] In urban sanitary landfills, in order to prevent leachate fr...
