Problems solved by technology

[0002] With the rapid development of the economy, the acceleration of industrialization and urbanization, the generation of municipal solid waste and industrial solid waste has increased sharply, and the land reuse of the original urban chemical industry area after relocation has gradually increased, while people's requirements for the living environment However, the anti-seepage effect of the current solid waste landfills, mine heap leaching sites, and high-concentration wastewater pools is not ideal
The development of anti-seepage technology in my country is relatively late, and pollution leakage has occurred in some simple garbage dumps and non-standard garbage landfills

Embodiment Construction

[0034] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as Figure 1 to Figure 3 The installation method of a vertical flexible barrier system based on earth and stone foundation shown includes the following steps:

[0036] The first step is to excavate the trench according to the pollution scope of the investigated pollution source, the hydrogeological conditions of the project and other factors. The ditch 1 width is about 1m, which is convenient for installation and reduces the workload, and the ditch 1 will be excavated to the natural anti-seepage layer 8 and then dig 1.5 meters. During the excavation process...

Abstract

The invention discloses a method for installing a vertical soft barrier system based on a soil-stone foundation. The method comprises the following steps of: digging a ditch for installing the vertical soft barrier system; refilling anti-seepage slurry into the ditch to form a retaining wall protection layer; installing an HDPE (High-Density Polyethylene) geomembrane in the ditch by using a support tool to form an HDPE geomembrane wall; chemically grouting and sealing the bottom of the HDPE geomembrane wall to form a bottom sealing layer; and withdrawing the support tool to form the vertical soft barrier system. Due to the adoption of the method, an anti-seepage function is ensured, seepage at a joint is prevented, and isolated liquid is effectively prevented from being dispersed; the horizontal dispersion of pollutants can be prevented and blocked for a long time; a connecting lock piece has a reversely-rotatable HDPE structure of which the positive and negative surfaces can be replaced by each other, is provided with a plurality of sealing chambers, can be used for accommodating a plurality of sealing materials and joint seepage detection systems, and is easy to install and operate; an expansion water blocking gasket can expand after contacting water, so that liquid is prevented from flowing through a porous sealing device, and persistent sealing is ensured; and a large installation depth is realized.

Description

technical field [0001] The invention relates to the fields of domestic garbage, industrial solid waste, hazardous waste, soil pollution and other environmental treatment, petrochemical industry and water conservancy technology, and in particular relates to an installation method of a vertical flexible barrier system based on earth and stone foundation. Background technique [0002] With the rapid development of the economy, the acceleration of industrialization and urbanization, the amount of municipal solid waste and industrial solid waste has increased sharply, and the land reuse of the original urban chemical industry area after relocation has gradually increased. People's requirements for the living environment However, the anti-seepage effect of the current solid waste landfills, mine heap leaching sites, and high-concentration wastewater pools is not ideal. The development of anti-seepage technology in my country is relatively late, and pollution seepage has occurred i...
