Embodiment Construction

[0026] In order to further illustrate the technical solution of the present invention, the present invention will be further described below through examples.

[0027] Such as Figure 1 to Figure 5 As shown, a flexible water-stop curtain that can quickly block the diffusion of site polluted groundwater includes "U"-shaped channel steel 8, "I"-shaped channel steel 6 and rubber airbag multi-unit assembly 2, and the "U"-shaped channel The steel 8 is arranged at the bottom of the base groove, and the length and width of the "U"-shaped channel steel 8 are the same as the length and width of the base groove respectively, and there are two "I"-shaped channel steels 6, all embedded without gaps Inside the "U"-shaped channel steel 8, two "I"-shaped channel steels 6 are respectively located on the left and right sides of the "U"-shaped channel steel 8, and the outer ends of the two "I"-shaped channel steels are respectively connected to the left and right sides of the base groove. The ...

Abstract

A flexible water-stop curtain that can quickly block the spread of polluted groundwater on the site. The "U"-shaped channel steel is set at the bottom of the foundation groove, and the two "I"-shaped channel steels are respectively located on the left and right sides of the "U"-shaped channel steel. The rubber The airbag multi-unit assembly is set in the cavity composed of "U"-shaped channel steel and "I"-shaped channel steel, and an "H"-shaped The sealing water-retaining rubber strip is provided with a polyurethane foaming agent filling layer between the "U"-shaped channel steel and the "I"-shaped channel steel and the rubber airbag multi-unit assembly; the present invention uses the rubber airbag multi-unit assembly as The flexible water-stop curtain uses "U"-shaped channel steel and "I"-shaped channel steel to fix the rubber airbag multi-unit assembly. The lowering, inflation and deflation recovery process of the rubber airbag multi-unit assembly is fast and simple, with high reliability. It reduces the technical risk brought by the traditional HDPE film construction.

Description

technical field [0001] The invention belongs to the field of environmental treatment of polluted sites, and in particular relates to a flexible water-stop curtain that can quickly block the diffusion of polluted groundwater in a site. Background technique [0002] In the treatment process of polluted sites, it is necessary to use vertical barrier technology to isolate the polluted medium to prevent the pollution radius from further expanding due to the migration of pollutants with precipitation or groundwater. The vertical barrier technology mostly adopts the water-stop curtain construction technology. The use of the water-stop curtain can block the migration of groundwater in the polluted site and control the pollution in the site to a certain extent, thus providing a certain guarantee for soil restoration and groundwater treatment. [0003] According to different construction materials, water-stop curtain technology can be divided into rigid water-stop curtain and flexible...
