Abstract
A warp knitted grill reinforcing composite geomembrane consists of a geo-fabric layer, an ordinary geomembrane layer and a warp knitted grill layer, and the composite layers are arranged together through heat sealing or bonding. The utility model adopts composite layers and integrates functions of three materials, including warp knitted grills, geotextiles and ordinary geomembranes, as a whole, and overcomes the disadvantages of low geomembrane intensity, over-high elongation percentage, high probability of puncturing, high probability of tearing and the like in the ordinary geomembrane. The warp knitted grill reinforcing composite geomembrane has the characteristics of high tensile strength, low elongation percentage, even longitudinal deformation and lateral deformation and high tearingstrength, and has the advantages of high puncture resisting intensity, high waterproof and drainage capacity, large friction factor and small coefficient of inertia expansion. The warp knitted grill reinforcing composite geomembrane is widely used in projects involved in railroads, tunnels, subways, culverts, express ways, sports halls, dams, hydraulic architectures, coastal shoals, reclamations,environmental protections and the like, and can play good water resisting, seepage-proofing, strengthening, reinforcing as well as protecting effects.
Description
Technical field
The utility model relates to the geomembrane that a kind of engineering is used, and is especially a kind of through compiling grid enhancing composite geo-membrane.
Background technology
At present, in order to prolong engineering application life, to solve engineering waterproofing antiseepage problem, at railway, tunnel, subway, culvert, speedway, Stadium, dykes and dams, hydraulic architecture, coastal beach, enclose and cultivate, a large amount of common geomembranes that use in the engineering such as environmental protection, in construction and use, expose deadly defects such as intensity is low, elongation rate is excessive, easily expose, easily tear, often easily because of under external force or the hard thing effect, geomembrane self breaks and causes engineering integral waterproofing antiseepage failure, and then shortens engineering application life greatly.
The utility model content
The utility model is for solving common geomembrane in construction and use, because the technological deficiency that its above-mentioned self deadly defect causes provides a kind of through volume grid enhancing composite geo-membrane.The utility model is by geotextile layer (1), common geotechnological rete (2), constitutes through compiling grid layer (3).
The concrete technical scheme of the utility model is: by geotextile layer (1), common geotechnological rete (2), constitute through compiling grid layer (3); Be provided with above the geotextile layer (1) through compiling grid layer (3), a side is provided with common geotechnological rete (2) above compiling grid layer (3), and a side is provided with geotextile layer (1) above the common geotechnological rete (2); The geotextile layer is continuous yarn non-woven fabrics, short silk nonwoven, woven fabric, geotextile, common geotechnological rete is high density polyethylene (HDPE) (HDPE) geomembrane, low density polyethylene (LDPE) (LDPE) geomembrane, ethene-vinyl acetate copolymer (EVA) geomembrane, polyvinyl chloride (PVC) geomembrane, through compile the grid enhancement layer be the warp-knitting polyester grid, through compile glass fiber grid, through compiling the polypropylene fibre grid; The warp through compiling grid layer (3) and the crosspoint of parallel are not crooked; Geotextile layer (1), common geotechnological rete (2), through compiling between the grid layer (3) by heat seal or bonding being set together.
The beneficial effects of the utility model are: the utility model is owing to adopt composite bed; collection is through compiling grid; the function of geotextile and three kinds of materials of common geomembrane is in one; not only has good waterproof, seepage control performance; simultaneously; because the geotextile laminar surface is coarse; structure is fluffy; soft flexible; thereby make through compiling grid and strengthen composite geo-membrane when constructing and use; play increase frictional force; cushioning and protection; make sharp keen hard object be difficult for piercing through the antiseepage film body; impervious barrier is played a very good protection; and owing in aforementioned composite membrane, introduce through compiling grid; the crosspoint that its maximum characteristics are warp and parallel is not crooked; be in straightened condition separately, both tied up firmly, can bear external force comprehensively more synchronously with lashing wire; distributed stress; and tensile strength height; elongation per unit length is low; when externally applied forces is torn the instantaneous of material, yarn can be gathered around collection along first breach, increases tearing toughness.Therefore, the invention solves deadly defects such as common geomembrane intensity is low, elongation rate is excessive, easily expose, easily tear, both had high-tensile, low elongation, in length and breadth to distortion evenly, characteristics that tearing toughness is high, have punctured resistance height, the anti-advantage that drainability is strong, friction factor is big, linear expansion coefficient is little again.At railway, tunnel, subway, culvert, speedway, Stadium, dykes and dams, hydraulic architecture, coastal beach, enclose and cultivate, use in a large number in the engineering such as environmental protection, play waterproof, antiseepage, enhancing reinforcement protection effect better.
