Abstract
The utility model discloses a novel double-layer composite geomembrane which is formed by jointing at least one impermeable layer and at least one additional layer through welding or bonding, wherein the impermeable layer is a high-density polyethylene geomembrane, and the additional layer is an ethylene vinyl acetate copolymer waterproofing membrane. In the utility model, the ethylene vinyl acetate copolymer waterproofing membrane is additionally arranged on the basis of a common geomembrane, so that the double-layer composite geomembrane has the characteristics such as excellent environmental stress crack resistance and toughness, high elongation rate, and strong weather resistance, and solves the technical problem that the common geomembrane is easy to damage due to the influence of environmental factors, thereby reducing material waste, saving manufacturing cost, improving waterproofing and anti-permeability effects of engineering, and ensuring engineering quality.
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 infrastructure 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, elongation per unit length 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, elongation per unit length 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 film.
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 fiber, polypropylene.
The beneficial effect of advantage of the present utility model and generation is:
The utility model increases ethylene-vinyl acetate copolymer macromolecule waterproof film 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, elongation per unit length 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, highway tunnel etc. are shaken, the waterproof and dampproof engineering of malformation; Seepage control projects such as underground workshop, highway tunnel, railway tunnel, bomb shelter; Various municipal engineering, refuse landfill, sewerage treatment 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 film, 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 fiber, polypropylene.
Described ethylene-vinyl acetate copolymer macromolecule waterproof film is to be primary raw material with the ethylene-vinyl acetate copolymer, mix an amount of modifier, antioxidant, ultra-violet absorber, colorant, filler, plasticizing agent etc., extrude three roll-ins through two sections and prolong, the sheet waterproofing materials 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 film 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, elongation per unit length 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, highway tunnel etc. are shaken, the waterproof and dampproof engineering of malformation; Seepage control projects such as underground workshop, highway tunnel, railway tunnel, bomb shelter; Various municipal engineering, refuse landfill, sewerage treatment 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 (1)
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 film.
