Abstract
Easily limit coarse-surface geomembrane is got rid of in welding, comprise geomembrane body, geomembrane body upper and lower surface some skid-proof points that are crisscross arranged, longitudinal both sides, region that skid-proof point is set in geomembrane body upper and lower surface are light face welding edge, light face welding edge and geomembrane body are integral type structure, and skid-proof point is anti-skidding salient point or the anti-skidding concave point with curved surfaces.The utility model arranges light face welding edge in the longitudinal both sides of geomembrane body, in work progress, geomembrane welds after just destroying attenuation without polishing more like this, not only time saving and energy saving, and improved welding quality, the sucked type structure of skid-proof point also contributes to improve geomembrane skidproof effect simultaneously, has advantages of simple in structure, easy to use.
Description
Technical field
The utility model relates to waterproofing materials technical field, is specifically related to a kind of easy welding and gets rid of limit coarse-surface geomembrane.
Background technology
Geomembrane is usingd plastic sheeting as antiseepage base material, and with the non-woven fabric compounded geotechnological impervious material forming, its barrier performance depends primarily on the barrier performance of plastic sheeting.At present, the plastic sheeting of the application of antiseepage both at home and abroad, mainly contain polyvinyl chloride (PVC) and polyethylene (PE), EVA(ethylene/vinyl acetate copolymer), in tunnel applications, also have design to use ECB(ethene vinyl acetate modified bitumen blend geomembrane), they are a kind of polymer chemistry flexible materials, proportion is less, extensibility is stronger, and adaptive deformation ability is high, corrosion-resistant, low temperature resistant, good frost resistance.
But often there is domatic landslide phenomenon in current geomembrane in the antiseepage project applications such as refuse landfill in the past, industrial antiseepage, aluminium manufacturer's red mud dump, affect on the one hand quality and the progress of engineering, affect on the one hand design and the application of geomembrane.In order to address this problem, adopted at first exasperate film abroad, but existing exasperate film is found exasperate film destroy exasperate in using, affect material overall performance, and can not directly weld, need to weld after the attenuation of polishing destruction weld strength wretched insufficiency, cause engineering leakage hidden danger, and existing exasperate film skidproof effect is also desirable not to the utmost.
Summary of the invention
The utility model provides a kind of easy welding to get rid of limit coarse-surface geomembrane, with what solve that prior art exists, can not directly weld the problem poor with skidproof effect.
The utility model comprises geomembrane body, solve technical scheme that its technical problem adopts and be geomembrane body upper and lower surface some skid-proof points that are crisscross arranged, longitudinal both sides, region that skid-proof point is set in geomembrane body upper and lower surface are light face welding edge, light face welding edge and geomembrane body are integral type structure, and skid-proof point is anti-skidding salient point or the anti-skidding concave point with curved surfaces.
Preferably, the skid-proof point above above-mentioned geomembrane body is anti-skidding salient point, and the skid-proof point below geomembrane body is anti-skidding concave point, and the structure of the similar sucker on anti-skidding concave point surface contributes to the bonding strength of geomembrane and coating cover material.
The utility model arranges light face welding edge in the longitudinal both sides of geomembrane body, in work progress, geomembrane welds after just destroying attenuation without polishing more like this, not only time saving and energy saving, and improved welding quality, the sucked type structure of skid-proof point also contributes to improve geomembrane skidproof effect simultaneously, has advantages of simple in structure, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
