Abstract
The utility model relates to an impermeable geomembrane. The impermeable geomembrane comprises an upper impermeable layer and a lower impermeable layer. A rib membrane layer is arranged between the upper impermeable layer and the lower impermeable layer in a composite mode, a resin membrane layer is arranged on the other surface of the upper impermeable layer in a composite mode, and a protection membrane layer is arranged on the other surface of the lower impermeable layer through a polyester non-woven cloth linear 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 anti-seepage geomembrane.
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 geomembrane of good seepage-proof property.
For achieving the above object; technical solution of the present utility model is: a kind of anti-seepage geomembrane; include impervious barrier and lower impervious barrier; between described upper impervious barrier and lower impervious barrier, be compounded with fascia layer; the another side of described upper impervious barrier is compounded with resin material rete, and the another side of described lower impervious barrier is compounded with protective film by polyester non-woven fabric laying.
Preferably, described upper impervious barrier and lower impervious barrier all adopt high density polyethylene (HDPE) to make.
Preferably, described fascia layer adopts yarn fabric.
Preferably, described protective film adopts ethylene-vinyl acetate copolymer macromolecule waterproof film.
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 anti-seepage geomembrane of the present utility model; include impervious barrier 1 and lower impervious barrier 2; described upper impervious barrier 1 and lower impervious barrier 2 all adopt high density polyethylene (HDPE) to make; between described upper impervious barrier 1 and lower impervious barrier 2, be compounded with fabric layer 3; the another side of described upper impervious barrier 1 is compounded with resin material rete 4; the another side of described lower impervious barrier 2 is compounded with protective film 6 by polyester non-woven fabric laying 5, and described protective film 6 adopts ethylene-vinyl acetate copolymer macromolecule waterproof film.
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.
