Embodiment Construction

[0013] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0014] The two-cloth and one-membrane composite geomembrane described in this embodiment, such as figure 1 As shown, it includes an upper geotextile layer 1, a middle film layer 2 and a lower geotextile layer 4 pressed by guide rollers, the middle film layer 2 is made of polymer synthetic material, and the upper geotextile layer 1 It is connected with the lower geotextile layer 4 as a whole, and a bending part 5 is provided at the junction. A plurality of reinforcing ribs 3 are made of high-density polyethylene material and are in the shape of a long cube.

[0015] The upper geotextile layer 1 and the lower geotextile layer 4 are staple-fiber needle-punched geotextiles. The staple-fiber needle-punched nonwoven geotextiles are made by opening synthetic chemical fibers and carding them into a web. Intertwined and fixed into cloth; th...

Abstract

The invention discloses a two-cloth-one-membrane composite geo-membrane, which includes an upper geotextile layer, a middle thin membrane layer, and a lower geotextile layer, which are laminated together through a guide roller. The middle thin membrane layer is prepared from a high-molecular synthetic material. The upper geotextile layer and the lower geotextile layer are connected to each other, a bended part arranged at the connection position. A plurality of reinforcing ribs are symmetrically disposed on the inner side surfaces, which are pressed against the middle thin membrane layer, of the upper geotextile layer and the lower geotextile layer. The reinforcing ribs are in a long-bar-shaped cubic structure. The upper geotextile layer and the lower geotextile layer are connected to each other, thereby reducing production and manufacturing difficulty and cost. The middle thin membrane layer is pressed by means of the upper and lower reinforcing ribs so that displacement between the middle thin membrane layer and the upper and lower geotextile layers is avoided, thereby improving the tensile strength and anti-deformation capability of the composite geo-membrane.

Description

technical field [0001] The invention relates to a geotechnical membrane, in particular to a two-cloth-one-film composite geotechnical membrane. Background technique [0002] The composite geomembrane is heated on one or both sides of the film by far-infrared oven, and the geotextile and geomembrane are pressed together by guide rollers to form a composite geomembrane, which is divided into one cloth and one film and two cloth and one film. Its width is 4~6m, and its weight is 200~1500g / m 2 , High physical and mechanical performance indicators such as tensile, tearing and bursting. Composite geomembrane is mainly used for anti-seepage, which can meet the needs of water conservancy, municipal, construction, transportation, subway, tunnel and other civil engineering. Due to the selection of polymer materials and the addition of anti-aging agents in the production process, it can be used in unconventional temperature environments. [0003] In the existing two-cloth-one-membra...
