Description
Technical field
The utility model is related to geotechnological technical field of membrane, specifically, more particularly to a kind of composite geo-membrane.
Background technology
Currently, with the rapid development of economic construction of China, various infrastructure need to largely be built, and built
Cheng Zhong, the bottom of numerous infrastructure are both needed to do water proof anti-seepage processing, now mainly carry out water proof anti-seepage using geomembrane.It is existing
Geomembrane has the following disadvantages：1st, its extexine is relatively smooth, and friction coefficient is smaller, suitable for the work that place is more smooth
Journey, if be laid on the larger seepage control project of grade of side slope, geomembrane and be laid on geomembrane fill object easily because with week
It encloses the deficiency of frictional force between medium interface and glides along side slope；2nd, since the area of monolithic composite geo-membrane can not be made very
Greatly, common processing mode is that in the construction process, the both sides of composite geo-membrane are carried out at field polish using construction personnel
Reason, is then connected fixation, only this link with binding material, and it is left to expend construction personnel 30% in work progress at the scene
The right time, and since construction personnel is difficult unified in polishing precision, it is easy to membrane body is caused to damage；3rd, geomembrane is soft
Yielding generation fold, is unfavorable for being laid with.In view of the foregoing, existing geomembrane use is not convenient enough；
Invention content
To solve the above-mentioned problems, the utility model discloses a kind of achievable polylith geomembranes to overlap rapidly answering for cooperation
Geomembrane is closed, stable structure is unlikely to deform.
The utility model is achieved through the following technical solutions：
A kind of composite geo-membrane, including set gradually from top to bottom the first geotextile layer, the first impervious barrier, first hot melt
Glue-line, the second impervious barrier, the second hot melt adhesive layer, grid layer and the second geotextile layer, the lower surface of second geotextile layer are
Crude face, the end of the composite geo-membrane have clamping structure, and the clamping structure is that one end is recessed to form recessed portion, another
End protrusion forms protrusion.
Second impervious barrier is staggered with the layer structure above and below it, one end of second impervious barrier with its above and below
Layer structure forms recessed portion, and the other end forms protrusion with the layer structure above and below it.
First impervious barrier and the second impervious barrier are made of high density polyethylene (HDPE).
Compared with prior art, the beneficial effects of the utility model are：
A kind of composite geo-membrane of the utility model be equipped with grid layer, make geomembrane have deform it is small, intensity is high, creep is small and
The characteristics of friction coefficient is big；The geotextile layer lower surface being bonded with ground is crude face, can increase geomembrane and surrounding medium circle
Frictional force between face avoids geomembrane and glides during waterproof, seepage control slope project use；The end of composite geo-membrane
Portion has clamping structure, is conducive to the overlap joint compounding practice between composite geo-membrane, easy for construction, efficient；The utility model
Stability is good, solves the problems, such as that common geomembrane is easily damaged by such environmental effects, improves the impervious effect of engineering waterproofing,
It ensure that the quality of engineering.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram that two pieces of composite geo-membrane splicings of the utility model use.
In figure：1st, the first geotextile layer；2nd, the first impervious barrier；3rd, the first hot melt adhesive layer；4th, the second impervious barrier；5th, the second heat
Melt layer；6th, grid layer；7th, the second geotextile layer；8th, crude face.
Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of composite geo-membrane, including the first geotextile layer 1, first the 2, first heat of impervious barrier set gradually from top to bottom
Melt layer 3, the second impervious barrier 4, the second hot melt adhesive layer 5,6 and second geotextile layer 7 of grid layer, second geotextile layer 7
Lower surface is crude face 8, and the end of the composite geo-membrane has a clamping structure, the clamping structure be one end be recessed to be formed it is recessed
Concave portion, the other end protrude to form protrusion.
Second impervious barrier 4 is staggered with the layer structure above and below it, one end of second impervious barrier 4 with its above and below
Layer structure formed recessed portion, the other end with its above and below layer structure formed protrusion.
First impervious barrier, 2 and second impervious barrier 4 is made of high density polyethylene (HDPE).
As shown in Figure of description Fig. 1, a kind of composite geo-membrane, including the first geotextile layer set gradually from top to bottom
1st, the first impervious barrier 2, the first hot melt adhesive layer 3, the second impervious barrier 4, the second hot melt adhesive layer 5,6 and second geotextile layer 7 of grid layer,
First impervious barrier 2 and the second impervious barrier 4 are made of high density polyethylene (HDPE), and the lower surface of the second geotextile layer 7 is crude face 8,
