Abstract
The utility model relates to a composite geomembrane. The composite geomembrane comprises an impermeable layer. A non-woven fabric layer and a needle-punched short-fiber geotextile are arranged on the upper side and the lower side of the impermeable layer in a composite mode respectively. An isolation layer is arranged on the other side of the needle-punched short-fiber geotextile in a composite mode through a self-adhesion layer, and a reinforcing layer is arranged on the other side of the non-woven fabric layer in a composite mode. The composite geomembrane has the advantages of being excellent in environmental stress cracking resistance and toughness, high in ductility and weather resistance and the like, solves the technical problem that a common geomembrane is easily influenced by the environmental factor and damaged, saves the manufacturing cost, improves the waterproof and impermeable effect of projects, and guarantees the quality of the projects.
Description
Technical field
The utility model relates to building materials technical field, is specifically related to a kind of composite geo-membrane.
Background technology
Geomembrane is as the impervious material in earth working material engineering construction, quite general.The general geotextiles adopting and the composite geomembrane structure material of geomembrane, in reservoir, dam, garbage disposal plant and farmland construction, be used widely now.But this geomembrane, in engineering is used, exposes the weakness such as environmental stress crack resistance is poor, poor toughness, elongation per unit length is low, weather resisteant is poor, often causes the decline of the impervious effect of engineering integral waterproofing, cause loss serious.
Utility model content
The purpose of this utility model be to provide a kind of simple in structure, tensile strength is high, the composite geo-membrane of good seepage-proof property.
For achieving the above object, technical solution of the present utility model is: a kind of composite geo-membrane, include impervious barrier, the both sides up and down of described impervious barrier are compounded with respectively nonwoven fabric layer and acupuncture short fiber geotextiles, the opposite side of described acupuncture short fiber geotextiles is compounded with separation layer by self-adhesive layer, and the opposite side of described nonwoven fabric layer is compounded with enhancement Layer.
Described impervious barrier is a kind of in polyethylene or polyvinyl chloride or ethylene/vinyl acetate copolymer antiseepage film.
Described nonwoven fabric layer is acupuncture or hot sticky polymeric staple fiber dimension chemical material.
Described separation layer adopts aluminium plating membrane.
Described enhancement Layer is glass wool cloth.
By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the feature such as composite geo-membrane of the present utility model has good environmental stress crack resistance, good toughness, elongation per unit length is high, weather resisteant is strong, solved that common geomembrane is subject to such environmental effects and the technical problem damaged, save cost cost, improve the impervious effect of engineering waterproofing, guaranteed the quality of engineering.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As shown in Figure 1, a kind of composite geo-membrane of the present utility model, include impervious barrier 1, described impervious barrier 1 is a kind of in polyethylene or polyvinyl chloride or ethylene/vinyl acetate copolymer antiseepage film, the both sides up and down of described impervious barrier 1 are compounded with respectively nonwoven fabric layer 2 and acupuncture short fiber geotextiles 3, described nonwoven fabric layer 2 is acupuncture or hot sticky polymeric staple fiber dimension chemical material, the opposite side of described acupuncture short fiber geotextiles 3 is compounded with aluminium plating membrane 5 by self-adhesive layer 4, and the opposite side of described nonwoven fabric layer 2 is compounded with glass wool cloth 6.
Above-described, be only a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
