Embodiment II

[0014] Example II, such as figure 2 It is shown that on the basis of the basic type of the present invention, a layer of reinforcement layer 3 is bonded by heat welding or bonding on the side of the anti-seepage layer that is not bonded to the foam layer.

[0015] The anti-seepage layer 1 of the present invention is a high-density polyethylene film or polyvinyl chloride film, the foam layer 2 is continuous foaming materials such as polystyrene or polyethylene, and the reinforcing layer 3 is materials such as glass fiber / polyester / polypropylene The weaving of cloth or netting.

[0016] image 3 Embodiment III of the present invention consists of two foam layers 2 and an anti-seepage layer 1 arranged between the two foam layers 2 .

[0017] Figure 4 It is an embodiment IV of the present invention, consisting of two layers of foaming layer 2, two layers of anti-seepage layer 1, and one layer of reinforcement layer 3. From top to bottom, it is followed by foam layer 2, anti-s...

Abstract

The invention discloses a foamed composite geomembrane for water control and seepage control in the project of reservoir, river, road, culverts, dam and the trash treating factory, which is prepared by welding or sticking at least one layer impervious layer (1) and at least one layer foaming layer (2). The connection side-face of impervious layer (1) with the foaming layer (2) can be equipped with a reinforcing layer (3), the impervious layer (1) being made up of high-density polyethylene film or polychloroethylene film, the foaming layer (2) made up of continuous foaming material such as polyphenylacetylene and polyethylene, the reinforcing layer (3) being a braided fabric or net of the glass fibre / polyester / polypropylene. It can avoid the problem of infiltration conduced by that the cutting needle pierces the geomembrane in the construction and usage process, and avoid the problem of stabbing working people. It is soft and elastic, and is facile to use or transport.

Description

technical field [0001] The invention is a foaming composite geomembrane used for waterproofing and anti-seepage in projects such as reservoirs, river courses, roads, culverts, dams, and garbage treatment plants. Background technique [0002] At present, the geomembrane used for waterproofing and anti-seepage in projects such as reservoirs, rivers, roads, culverts, dams, and garbage treatment plants is mainly composed of cross-linked polyethylene film and non-woven fabric layer. During the acupuncture production process, there are often broken needles. During the construction process, the broken needles in the non-woven fabric often stab the construction personnel; leak. Contents of the invention [0003] The purpose of the present invention is to provide a foamed composite geomembrane, which can effectively solve the leakage problem caused by puncturing the membrane during construction and use, and can also avoid stabbing construction personnel during construction. [00...
