Construction method of combined anti-seepage body with horizontal anti-seepage function and vertical anti-seepage function

Abstract

The invention discloses a construction method of a combined anti-seepage body with a horizontal anti-seepage function and a vertical anti-seepage function. The adopted combined anti-seepage body comprises a vertical anti-seepage wall (7), a composite anti-seepage engineering structure (9) and a horizontal anti-seepage system. The composite anti-seepage engineering structure (9) is composed of a vertical anti-seepage inner wall (9-1), an inner wall covering plate (9-3) located on the upper portion of the vertical anti-seepage inner wall (9-1) and extending towards one side of the solid waste storage yard / polluted site, a vertical anti-seepage outer wall (9-2) and an outer wall covering plate (9-4) located on the upper portion of the vertical anti-seepage outer wall (9-2) and extending outwards. The horizontal anti-seepage system is composed of a base layer (5), an anti-seepage material protection layer (4), a horizontal anti-seepage layer (3), an ecological base layer (2) and an ecological layer (1) from bottom to top. The method is suitable for solid waste piles in different shapes, such as the ground, pits and mountain pits, is particularly suitable for being applied under the condition that solid waste is much higher than the ground, meets the process requirements of horizontal seepage prevention and vertical seepage prevention, saves clay resources, reduces the earthwork usage amount, and is simple and convenient to construct, low in cost and good in effect.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and anti-seepage engineering construction, and in particular relates to a construction method with a horizontal anti-seepage and vertical anti-seepage combined structure, which is suitable for solid waste piles / polluted sites of different shapes, such as storage on ground, pits and hills. The anti-seepage treatment of the solid waste site is especially suitable for the situation where the solid waste pile is much higher than the ground. Background technique [0002] Due to historical reasons, many enterprises generate a large amount of solid waste in the production process, such as steel slag from steel mills, copper smelting waste slag, stripped waste rock (soil) from mining and so on. Since the generated industrial solid waste has not been treated in time and used effectively, the storage volume of industrial solid waste in some areas has grown rapidly, which has brought great p...
