Background technology

Geomembrane is a kind of material conventional in waterproof, seepage control occasion, existing geomembrane thinner thickness, comparatively soft, the general effect not possessing tension, tear-proof, usually be applicable to conventional stationary occasion, use under being not suitable for dynamic environment, the stability in use of geomembrane is not high;

It is many that film body produces electrostatic, although electricity is not high, be easy to cause to produce, constructor has electrical sensation and affect work, and these electrostatic do not have release channel relatively, the some mechanical equipment be easy to being connected with geomembrane impacts;

Geomembrane structure is all the same, mainly take the technical approach of individual layer high density polyethylene (HDPE) impervious barrier, in construction or use procedure, crack-induced stress easily makes individual layer impervious barrier occur crack, and then it is damaged to cause geomembrane to occur, easily makes shorten the application life of geomembrane; High density polyethylene (HDPE) is combustible material, if run into naked light in work progress, or uses under some special occasions, there is potential safety hazard; Its top does not have the place that can make marks yet, so cannot distinguish when geomembrane large area uses, needing the thing being started by geomembrane just to know its underpart, is very trouble;

Simultaneously, the area of monolithic geomembrane can not do very large, at present, conventional processing mode is in work progress, utilizes the both sides of constructor to civil engineering many structures geomembrane to carry out field polish process, is then connected and fixed with binding material, only this link, the time of constructor about 30% can be expended at the scene in work progress, and due to constructor's very difficult unification in polishing precision, be easy to cause damage to film body.
