Abstract
The utility model discloses a novel double-layer composite geomembrane, which is formed by at least one impermeable layer and at least one additional layer through hot smelting connection or adhesive engagement, wherein the impermeable layer is a high-density polyethylene geomembrane, and the additional layer is an ethylene-vinyl acetate copolymer macromolecular waterproof membrane. The utility model adds the ethylene-vinyl acetate copolymer macromolecular waterproof membrane on the basis of the ordinary geomembrane, so the double-layer composite geomembrane of the utility model has the characteristics of good environment stress cracking resistance performance, good toughness, high extending rate, strong weatherability and the like, and the technical problem that the ordinary geomembrane can be damaged through being easily influenced by environment factors can be solved, so the material waste can be reduced, the cost and the manufacture price can be saved, the engineering waterproof and seepage-proof effect can be improved, and the engineering quality can be ensured.
Description
Technical field
The utility model relates to the geomembrane that a kind of engineering is used, especially a kind of novel double-layer composite geo-membrane.
Background technology
Current, in China's capital construction process, relate to a large amount of water proof anti-seepage engineerings, use common geomembrane in a large number for the water proof anti-seepage that solves engineering, but this geomembrane is in engineering is used, expose that environmental stress crack resistance is poor, weakness such as poor toughness, percentage elongation are low, weather resisteant difference, often cause the decline of the impervious effect of engineering integral waterproofing.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of have good environmental stress crack resistance, the good strong novel double-layer composite geo-membrane of toughness, percentage elongation height, weather resisteant are provided.
The technical solution of the utility model is: a kind of novel double-layer composite geo-membrane, by one deck impervious barrier at least with the thermal welding of one deck extra play or adhesive joint are formed at least, described impervious barrier is a high-density polyethylene geomembrane, and described extra play is an ethylene-vinyl acetate copolymer macromolecule waterproof membrane.
As preferably, described extra play is provided with enhancement Layer away from the side of impervious barrier, and this enhancement Layer is the establishment cloth or the net of materials such as glass fibre, polypropylene.
The beneficial effect of advantage of the present utility model and generation is:
The utility model increases ethylene-vinyl acetate copolymer macromolecule waterproof membrane on common geomembrane basis, make two-layer compound geomembrane described in the utility model have characteristics such as good environmental stress crack resistance, good toughness, percentage elongation height, weather resisteant be strong, solved that common geomembrane is subject to such environmental effects and the technical problem damaged, thereby reduced the waste of material, save the cost cost, improve the impervious effect of engineering waterproofing, guaranteed the quality of engineering.The utility model laying construction is convenient, do not produce drift, can be widely used in that subway engineering, railway, vcehicular tunnel etc. are shaken, the waterproof and dampproof engineering of malformation; Seepage control projects such as underground workshop, vcehicular tunnel, railway tunnel, bomb shelter; Various municipal works, refuse landfill, sewage disposal civil air defense constructions and installations, checkdam, reservoir field.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment 1: as shown in Figure 1, a kind of novel double-layer composite geo-membrane, form by one deck impervious barrier 1 and 2 thermal weldings of one deck extra play or adhesive joint, described impervious barrier 1 is a high-density polyethylene geomembrane, described extra play 2 is an ethylene-vinyl acetate copolymer macromolecule waterproof membrane, described extra play 2 is provided with enhancement Layer 3 away from the side of impervious barrier 1, and this enhancement Layer 3 is the establishment cloth or the net of materials such as glass fibre, polypropylene.
Described ethylene-vinyl acetate copolymer macromolecule waterproof membrane is to be primary raw material with the ethylene-vinyl acetate copolymer, mix an amount of modifier, antioxidant, ultra-violet absorber, colouring agent, filler, plasticizer etc., extrude three roll-ins through two sections and prolong, the sheet waterproof material of being processed into through operations such as shaping, cooling, check, bundling, packings that curls.
The utility model increases ethylene-vinyl acetate copolymer macromolecule waterproof membrane on common geomembrane basis, make two-layer compound geomembrane described in the utility model have characteristics such as good environmental stress crack resistance, good toughness, percentage elongation height, weather resisteant be strong, solved that common geomembrane is subject to such environmental effects and the technical problem damaged, thereby reduced the waste of material, save the cost cost, improve the impervious effect of engineering waterproofing, guaranteed the quality of engineering.The utility model laying construction is convenient, do not produce drift, can be widely used in that subway engineering, railway, vcehicular tunnel etc. are shaken, the waterproof and dampproof engineering of malformation; Seepage control projects such as underground workshop, vcehicular tunnel, railway tunnel, bomb shelter; Various municipal works, refuse landfill, sewage disposal civil air defense constructions and installations, checkdam, reservoir field.
Embodiment 2: present embodiment is made up of 2 staggered thermal weldings of two-layer impervious barrier 1 and two-layer extra play or adhesive joint, and all the other structures are identical with embodiment 1.
Claims (2)
1. novel double-layer composite geo-membrane, comprise one deck impervious barrier at least, it is characterized in that: also comprise one deck extra play at least, they form through thermal welding or adhesive joint, described impervious barrier is a high-density polyethylene geomembrane, and described extra play is an ethylene-vinyl acetate copolymer macromolecule waterproof membrane.
2. novel double-layer composite geo-membrane according to claim 1 is characterized in that: described extra play is provided with enhancement Layer away from the side of impervious barrier, and this enhancement Layer is the establishment cloth or the net of materials such as glass fibre, polypropylene.
