Abstract
The utility model discloses a polyester filament composite geomembrane. The heat-shrinkable fabric comprises a geotextile layer and a film layer, wherein the geotextile layer and the film layer are integrated into a whole through heat synthesis. The utility model discloses not only have good stretch-proofing, tear resistance, have good prevention of seepage function again, but wide application in large-scale capital construction engineering such as highway, railway, landfill, airport can effectively prevent the loss of water and soil particle, strengthens the intensity and the wholeness and the processing convenience on road surface, and is with low costs.
Description
One, technical field:
The utility model relates to a kind of geomembrane, and is especially relevant with the PFY composite geo-membrane.
Two, background technology
Though existing spun-bonded continuous yarn geotextiles intensity is higher,, can't satisfy the large-scale capital construction projects designing requirement that hydraulic engineering and highway, railway, refuse landfill, subterranean tunnel etc. need barrier performance because its barrier properties is relatively poor.
Three, summary of the invention
The purpose of this utility model provides a kind of both had good stretch-proof, tear resistance, the PFY composite geo-membrane that has good antiseepage function again.
For achieving the above object, the utility model is realized by following technical solution: the PFY composite geo-membrane, comprise geotechnological layer of cloth and rete, and geotechnological layer of cloth and rete are by the thermal synthesis one.
Described PFY composite geo-membrane, geotechnological layer of cloth have two layers, and rete is between two geotechnological layer of cloths.
Described PFY composite geo-membrane, rete have two layers, and geotechnological layer of cloth is between two retes.
Described PFY composite geo-membrane, geotechnological layer of cloth are the PFY geotextiles, and rete is a polyethylene geotextiles film.
The utility model compared with prior art, have the following advantages: (one) is owing to adopt composite bed, the function that integrates two kinds of materials, not only have good stretch-proof, tear resistance, has good antiseepage function again, can be widely used in large-scale capital construction projects such as hydraulic engineering and highway, railway, refuse landfill, subterranean tunnel, can effectively prevent the seepage of sealing and the loss of soil particle, strengthen the intensity and the integraty on road surface; (2) be to adopt the heat seal mode compound, easy to process, cost is low.
Four, description of drawings
Fig. 1 is the structural representation of the utility model PFY composite geo-membrane two-layer equation.
Fig. 2 is the structural representation of the utility model PFY composite geo-membrane cloth film cloth three-layer type.
Fig. 3 is the structural representation of the utility model PFY composite geo-membrane film cloth film three-layer type.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the PFY composite geo-membrane, comprise geotechnological layer of cloth 1, and rete 2, geotechnique's layer of cloth 1 and rete 2 are bonded into one by heating, geotechnique's layer of cloth 1 is the PFY geotextiles, and rete 2 is a polyethylene geotextiles film, and its technology is: a PFY geotextiles+polyethylene geotextiles film → compounding machine heat seal → cloth one film → side cut → rolling → test package → finished product warehouse-in.
Embodiment 2: as shown in Figure 2, geotechnique's layer of cloth 1 has two layers, rete 2 is between two geotechnological layer of cloths 1, and its technology is: PFY geotextiles+polyethylene geotextiles film → compounding machine heat seal → two cloth, one film → side cut → rolling → test package → finished product warehouse-in, all the other are with embodiment 1.
Embodiment 3: as shown in Figure 3, geotechnique's layer of cloth 1 one deck, rete 2 has two layers, and geotechnological layer of cloth 1 is between two retes 2, its technology is: a PFY geotextiles+polyethylene geotextiles film → compounding machine heat seal → cloth two film → side cut → rollings → test package → finished product warehouse-in, all the other are with embodiment 1.
Claims (4)
