Embodiment Construction

[0014] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, a vertical flexible barrier system for ecological environment restoration, the vertical flexible barrier system 4 is an impermeable wall, the vertical flexible barrier system passes through the groundwater layer 3 under the pollutant 1, and penetrates into the impermeable layer 5; Wherein, the vertical flexible barrier system 4 is a HDPE geomembrane wall made of HDPE geomembrane material, and the vertical flexible barrier system 4 surrounds the pollutant 1 and the polluted soil base 2 in a circle.

[0016] Since the polluted soil contains a large amount of toxic and harmful substances, the vertical flexible anti-seepage membrane wall made of HDPE geomembrane material has good chemical resistance, extremely low permeability, aging resistance, and effectively blocks pollutants.

[0017] Set up a ci...

Abstract

The invention relates to a vertical flexible barrier system for remediation of an ecological environment, the vertical flexible barrier system is a water-proof HDPE (high-density polyethylene) geomembrane wall, and the vertical flexible barrier system penetrates through an underground water layer below pollutants and is driven into a water-proof layer. By arranging the vertical flexible anti-seepage membrane wall, a pollution region can be thoroughly isolated from outside, the spread of pollution can be avoided, and surrounding soil and underground water can be effectively protected; and furthermore, the structure is simple and the construction cost is low.

Description

technical field [0001] The invention relates to the technical field of ecological environment restoration and pollution control, in particular to a vertical flexible barrier system for ecological environment restoration. Background technique [0002] While my country's economy is developing rapidly, it has also brought great damage to the natural environment. For example, a large number of chemical plants, landfills without anti-seepage, red mud dumps, mine heap leaching sites, etc. pollute the soil and extend to groundwater, causing harmful substances in this area to continue to spread and pollute the surrounding environment, seriously affecting the The lives of the people around them can cause casualties and accidents in severe cases. The necessary means are urgently needed to isolate the contaminated area from its surroundings. Contents of the invention [0003] The object of the present invention is to design a vertical flexible barrier system for ecological environm...
