Abstract
The utility model discloses a geomembrane with rough surface and smooth edge, whose single side edge or double-side edge are smooth surfaces, other parts are rough surfaces. The width of the smooth surface edge is 10-30 cm. And the preferable width is 5-15 cm. The smooth surface for welding remained at the two edges of the geomembrane with rough surface provided by the utility model can be applied with common thermocompression bonder for realizing high reliable welding as welding of the PE geomembrane with smooth surface, thereby realizing that only some improvements have be done to the original annular die head or T die, and the die head of the product is suitable to be customized. Moreover the method for welding the geomembrane is the same as the smooth PE geomembrane, and the rough surface of large area in the middle can provide large friction force for mud, and the smooth zone at the welding line point does not influence the whole body, thereby guarantying the welding quality without influencing the welding construction efficiency. The technical scheme provided by the utility model for resolving the problem has the advantages of simpleness, convenience, practicality, low cost and good effect.
Description
Technical field
The utility model relates to a kind of construction works geomembrane, relates in particular to a kind of coarse-surface geomembrane of smooth edge.
Background technology
At home and abroad, geomembrane has been widely used in places such as refuse landfill, mine, grain depot, oil depot, road and bridge engineering, tunnel culvert, garden landscape, afforestation project, reservoir sewerage treatment at present.But on side slope because common PE geomembrane smooth surface, landfill earth sandstone easy glide very thereon, cause the ground shakiness, so invented coarse-surface geomembrane abroad, the artificial matsurface of making in its PE geomembrane surface, landfill skin friction in earth is big, with firmly difficult sliding change of the engineering of its construction.But add rough geomembrane welding and brought trouble, must adopt big Pressure Welding to meet sb. at the airport and higher welding temperature, even now still is difficult to satisfy the requirement of welding quality, welding procedure speed also is subjected to great influence, and the weld seam of the thousands of rice of engineering as long as point goes wrong whole engineering all fail those recessive problems that just show in a few years particularly.Impelling coarse-surface geomembrane to use is obstructed.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned defective of coarse-surface geomembrane, the coarse-surface geomembrane of a kind of convenient welding, reliable and simple in structure, smooth edge easily and effectively is provided.
The purpose of this utility model realizes by following scheme: one-sided edge or place, both sides of the edge are shiny surface, and other parts are exasperate.
The width at shiny surface described in the utility model edge is 10 to 30cm.Preferred width is 5 to 15cm.
Coarse-surface geomembrane of the present utility model is because the welding shiny surface that two edges are left, can be the same with welding light face PE geomembrane, adopt common thermocompression bonder can realize highly reliable welding, realize this product as long as on former annular die head or T mould, do a little improvement, also can customizedly be suitable for producing the die head of this product.And the same with the smooth PE geomembrane of welding, middle large-area exasperate can offer the big frictional force of earth, and the smooth domain of commissure can not guarantee that like this welding quality can not impact the welding efficiency of construction again to having influence on integral body.The technical scheme that the utility model is dealt with problems is simple, convenient and practical, with low cost, effective.
