Combined anti-seepage body for solid waste pile pollution prevention and ecological restoration

Abstract

The invention discloses a combined anti-seepage body for solid waste pile pollution prevention and ecological restoration. The 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 pile body, 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 heaps 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 requirements of horizontal seepage prevention and vertical seepage prevention, saves clay resources, reduces the earthwork usage amount, is simple and convenient to construct, low in cost and good in effect, and is suitable for popularization and application. The device is especially suitable for being applied under the condition that solid waste piles are much higher than the ground.

Description

technical field [0001] The invention belongs to the technical field of solid waste pollution prevention, and in particular relates to a combined anti-seepage structure for solid waste pollution prevention and ecological restoration, which is especially suitable for application when the solid waste is much higher than the ground. Background technique [0002] Due to historical reasons, many enterprises produce a large amount of solid waste during the production process, such as steel slag from steel mills, copper smelting waste slag, stripping waste rock (soil) from mining and so on. Since the industrial solid waste generated has not been processed and effectively utilized in a timely manner, the storage volume of industrial solid waste in some areas has increased rapidly, which has brought great pressure to the surrounding environment. The number of industrial solid waste storage yards is huge, and there are many types. There are very few ways to comprehensively utilize them...
