Abstract
A geomembrane with a spinning layer comprises a geomembrane main body (1) which is 0.8-2.5mm in thickness; both sides of the geomembrane main body (1) in the vertical direction are provided with lap-joint plain edges (3); the spinning layer (2) is arranged on the geomembrane main body (1), and is formed by unevenly distributed filiform small particles. The lap-joint plain edges (3) are polished geomembranes, and are 16-28cm in width. The geomembrane with the spinning layer can enhance the friction force between the geomembrane and a spreading surface, thereby improving the antiskid property of the membrane.
Description
Technical field
The present invention relates to a kind of geomembrane, especially refuse landfill plastic leakage-proof geomembrane is specifically surperficial with a kind of thread short grained geomembrane.
Background technology
At present, as the antiseepage base material, with the non-woven fabric compounded geotechnological impervious material that forms, its barrier performance depends primarily on the barrier performance of plastic sheeting to geomembrane with plastic sheeting.At present, the plastic sheeting that antiseepage is both at home and abroad used, mainly contain polyvinyl chloride (PVC) and polyethylene (PE), EVA(ethylene/vinyl acetate copolymer), also have design to use ECB(ethene vinyl acetate modified bitumen blend geomembrane in the tunnel applications), they are a kind of polymer chemistry flexible materials, proportion is less, extensibility is stronger, and the adaptive deformation ability is high, and is corrosion-resistant, low temperature resistant, good frost resistance.
The plastic civil engineering film is normally used for the antiseepage occasion, for example refuse landfill, and the existing plastic civil engineering film overwhelming majority is the light face geomembrane of the face of pleasing both parties, for example blowing geomembrane.Light face geomembrane, its smooth surface, during use and the frictional force that paves between face little, easily cause relative slippage with the face of paving in the use procedure, especially pave domatic the integral slipping of easier generation film.By adding the nail location, can cause again face damaged, cause seepage, subsidize the nail hole again so that workload increases greatly, reality also is unallowed.
?
Summary of the invention
It is little to the objective of the invention is the frictional force that exists for light face geomembrane, easily causes the problem with the relative slippage of the face of paving in the use procedure, proposes a kind of with thread short grained geomembrane.
Technical scheme of the present invention is:
A kind of geomembrane with spinning layer is with thread short grained geomembrane, and it comprises the geomembrane body, and geomembrane body longitudinally both sides is equipped with the overlap joint plain edge, is provided with spinning layer at the geomembrane body.
Spinning layer of the present invention is the thread granule of uneven distribution.
The thickness of geomembrane body of the present invention is 0.8-2.5mm.
Overlap joint plain edge of the present invention is light face geomembrane.
The width of overlap joint plain edge of the present invention is 16-28cm.
Beneficial effect of the present invention:
Geomembrane with spinning layer of the present invention can strengthen geomembrane and the frictional force between the face that paves, and improves the skid resistance of film.
Description of drawings
Fig. 1 is structural representation of the present invention.
?
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of geomembrane with spinning layer, it comprises geomembrane body 1, geomembrane body 1 longitudinally both sides is equipped with overlap joint plain edge 3, is provided with spinning layer 2 at geomembrane body 1.
Spinning layer 2 of the present invention is the thread granule of uneven distribution.
The thickness of geomembrane body 1 of the present invention is 0.8-2.5mm.
Overlap joint plain edge 3 of the present invention is light face geomembrane.
The width of overlap joint plain edge 3 of the present invention is 16-28cm.
Geomembrane with spinning layer of the present invention can strengthen geomembrane and the frictional force between the face that paves, and improves the skid resistance of film.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
