Embodiment Construction

[0034] Such as figure 1 , figure 2 , image 3 As shown, the present invention provides a kind of airtight connection device of vertical flexible cut-off wall, which is used for the connection of two adjacent flexible membranes in the groove. For convenience, the horizontal extension direction of the groove is called horizontal direction, and the groove width direction is called longitudinal , the airtight connection device includes a three-link bearing structure 2, a cross support joint 1 and a flexible membrane insertion structure 3, wherein:

[0035] The three-link supporting structure 2 is composed of three connecting rings 21, 22, and 23 with gaps that are integrally connected in the horizontal direction. The three connecting rings 21, 22, and 23 have the same size, and the material is preferably HDPE material. Each connecting ring The outer diameters of 21, 22, and 23 are about 90 mm, and the thickness is about 8.2 mm; the connecting rings 21 and 23 on both sides have ...

Abstract

The invention provides an airtight connection device and method for a vertical flexible anti-seepage wall. The airtight connection device comprises a triple connecting ring bearing structure, a supporting joint and a flexible film inserting structure, wherein the triple connecting ring bearing structure is formed by integrally connected three connecting rings with seams in a transverse direction;the connecting rings on the two sides are provided with film passing seams towards the transverse outer side, and the middle connecting ring is provided with a built-in open seam towards the longitudinal seam; one side of the supporting joint is inserted into the built-in open seam and is fixed; the flexible film inserting structure comprises a flexible film and a core wire connected with the sideof the flexible film; the core wire is inserted into the connecting ring on side of the triple connecting ring bearing structure; and the flexible film passes through the film passing seam. The jointstructure and the airtight structure are integrated, thereby facilitating construction, preventing conflict, increasing construction speed and improving anti-seepage effect.

Description

technical field [0001] The invention relates to a sealing connection device of a vertical flexible anti-seepage wall and a construction method thereof, and relates to the field of environmental treatment of polluted sites. Background technique [0002] With the rapid economic development, the problem of environmental pollution is becoming more and more serious. Some pollutants leaked during the production process, long-term stockpiled solid waste, or leachate produced by landfills will leak underground. In the treatment of polluted sites, in many cases, it is necessary to block the polluted medium to prevent pollution The further expansion of the radius will cause harm to the human body and the surrounding environment. [0003] Barrier technology refers to the technology that blocks the migration and diffusion of pollutants in the soil medium by laying a barrier layer, isolates the polluted medium from the surrounding environment, and prevents pollutants from contacting the...
