Abstract
The utility model relates to a high-strength reinforced composite anti-seepage geo-membrane textile which comprises geo-membranes, tricot machine waved textiles and needle-punched nonwoven geo-textiles. The geo-membrane textile is characterized in that tricot machine waved textiles are applied among the geo-membranes, and the needle-punched nonwoven geo-textiles are applied on the geo-membranes to be calendered, heated and compounded. The physical mechanical performance indexes of the geo-membrane textile such as tensile resistance, tear strength, CBR anti-bursting value, seepage coefficient etc. are higher than the ordinary geo-membrane, and the geo-membrane textile also has strong penetration resistance, thereby solving the technical problem that the ordinary geo-membrane is burst easily by hard stone; the geo-membrane textile provided by the utility model reduces the waste of the material, saves the cost, improves the waterproof and anti-seepage effect of the project, ensures the project quality ; therefore, the geo-membrane textile can be widely applied to the civil engineering, the hydraulic engineering and the environmental engineering such as architecture, road, railroad, subway, arch culvert, tunnel, riverway, dike, waterproof engineering, water supply and drainage, landfill, sewage disposal factory etc.
Description
Technical field
The utility model relates to a kind of water proof anti-seepage geomembrane cloth.
Background technology
Current, the layering reinforcement of highway and railway slope; The protection of impervious barriers such as the isolation of earth rock cofferdam weak soil and piece stone, tunnel, reservoir dam, river course, gutter, artificial lake; Isolation between refuse landfill filtrate and the rubbish; The isolation of asphalt surface and roadbed and the enhancing on road surface, these national basis Facilities Construction engineerings all relate to the water proof anti-seepage problem.Use a large amount of common geomembranes now on the engineering, the weatherability that exposes anti-environment is poor, intensity is low, easily expose, easy weakness such as jackknifing, often easily breaks under the huge effect of external force and causes the decline of the impervious effect of engineering integral waterproofing owing to the material of common geomembrane own.
Summary of the invention
In view of the problem that above-mentioned common geomembrane occurs in the water proof anti-seepage engineering, the purpose of this utility model aims to provide the compound anti-seepage geomembrane cloth of a kind of high-strength reinforcement.Promptly between geomembrane, lay the footpath and compile woven cloth, on geomembrane, lay the acupuncture non-woven geotextile again, reach the unexistent effect that significantly improves water proof anti-seepage in length and breadth to high-tensile, high CBR bursting value, high impervious coefficient, low elongation of common geomembrane cloth thereby play the effect of strengthening for common geomembrane cloth reinforcement.
The purpose of this utility model is to be achieved through the following technical solutions:
The compound anti-seepage geomembrane cloth of a kind of high-strength reinforcement is by compiling woven cloth calendering, heat and be composited in acupuncture non-woven geotextile, geomembrane and footpath.Lay the footpath between the geomembrane and compile woven cloth, the acupuncture non-woven geotextile is laid on the geomembrane.
Above-mentioned geomembrane is polyvinylchloride or polythene PE or high-molecular polythene HDPE or ethylene-vinyl acetate copolymer EVA.
Above-mentioned footpath is compiled woven cloth and is compiled weaving polyester cloth for the footpath, or woven Polypropylene is compiled in the footpath.
Above-mentioned acupuncture non-woven geotextile is the long filament non-woven geotextile, or short silk non-woven geotextile.
The beneficial effect of advantage of the present utility model and generation is:
1, tension of the present utility model, tear-proof, the anti-bursting value of CBR, transmission coefficient wait until that the physical and mechanical property index is higher than common geomembrane cloth, anti-penetration capacity is strong, solved the technical problem that geomembrane cloth subjects to the hard building stones bursting of foundation pad, thereby reduce the waste of material, save the cost cost, improve the impervious effect of engineering waterproofing, guaranteed the quality of engineering.The performance indications of the utility model and common geomembrane cloth are according to as shown in the table:
2, the utility model passes through gluing heat seal process by geomembrane, acupuncture geotextiles and footpath are compiled the woven cloth geosynthetics that is composited, quality is firm, compact conformation, have outstanding water proof anti-seepage, isolation and reinforcement protection effect, anti-permeability is good, and is high temperature resistant, anti-freezing, ageing-resistant, corrosion-resistant;
3, the utility model is easy and simple to handle, construction is (the gluing or heat seal bonding machine welding of junction all can) fast, moderate cost can be widely used in civil engineering, hydraulic engineering and Environmental Engineerings such as railway, highway, sports buildings, artificial dykes and dams, civil construction, culvert tunnel, coastal (river) embankment, sewerage treatment chemical industry pond, refuse landfill.
