Plastic blind ditch is wrapped in filter cloth group style plastic blind ditch by the plastic core in vitro. Plastic core is a thermoplastic synthetic resin as a main raw material, and extruded through the nozzle after the modification, in the hot melt state, a thin plastic filaments, and then through the molding apparatus, the extruded plastic wire welded junction to form a three-dimensional network structure. Extruded through the nozzle after the heating of the thermoplastic synthetic resin melted fiber filaments stacked together, and contact points and sintered three-dimensional porous material. Plastic blind ditch, also known as the blind ditch, culverts, etc., it is heated to melt the thermoplastic synthetic resin extruded through the nozzle filaments overlap, and connecting point welding made three-dimensional porous material. Products have a variety of circular and rectangular cross-section. Different recipe production of high temperature resistant, flame retardant, resistant to strong acid and alkali, high flexibility, high hardness and can be customized according to the different characteristics of the product. Plastic blind ditch engineering applications. Highway, railway roadbed and road shoulder drainage. Retaining wall on the back drainage (vertical, horizontal drainage) 3. Tunnels, underpasses drainage 4. Hillside, Dipo slope drainage soft foundation treatment horizontal drainage 6 sports grounds, golf courses, airports, parks and other green drainage 7. heap coal yard, landfill, composting field site drainage. vacuum engineering methods of drainage blanket 9. agriculture, horticulture, underground irrigation and drainage system 10 roof garden drainage 11. sewage treatment filter material characteristics: high pressure polyethylene extrusion processed from both sides have different rib and groove to accommodate the needs of drainage, water stop and fixed, relative to other soft plastic The plate has a certain stiffness, favorable to maintaining the drainage cavity, a smaller proportion of the material, the cost is relatively lower, cold corrosion-resistant bacteria the eclipse and buried in the tunnel lining is not easy to aging, long life and other characteristics. 1, the composition of the fibers of the plastic blind ditch material about 2mm strands pull each other point fused to form a type, a three-dimensional mesh body the truss principle of its principles and steel structure creation. The surface openings Bailey 95-97%, there is more than 5 times the bore tube, the the resin mesh tube 3-4 times, the surface water absorption is very high. 2, since the three-dimensional structure, its porosity is 80-95%, and constituting the same lightweight, space and management compressive properties than the pipe structure of the resin is more than 10 times stronger, Therefore, even if due to overload is pressed, but is a perspective structure, the residual gap of 50% or more, there is no barrier of water issues, without regard to the earth pressure will be crushed. 3, the compressive strength. 250KPa under pressure, the compression ratio is less than 10%. 4, plus the anti-aging agent, durable, underwater, soil, etc. can also be set for decades to ensure stable. 5, compressive strength and flexibility, construction corners song bit is handy if the backfill depth of about 10cm, can also be used bulldozers backfilling. 6, plastic blind ditch membrane under different soil conditions chosen to fully meet the needs of the project, and to avoid the disadvantages of the old product membrane single. Plastic blind ditch light weight, very easy to install on-site construction, construction efficiency is greatly accelerated. 7, due to the hot melt molding without the use of adhesives, it is not the binder aging and peeling caused the collapse. 8, plastic blind ditch the surface melt the modified plastic wire with the toughness of many root knot, there is no pressure off, destroyed possible. 250kpa under pressure, the cross-sectional porosity remains above 60%, even if a large pressure is applied, there is always pass the water voids, and still 10-15% of the pores, and good resilience. 9, because of the above characteristics, it is traditional blind ditch problems, such as uneven settlement or due to overloading, partial occlusion, crushed gap no cause functional interrupt can be resolved through the plastic blind ditch material . Plastic blind ditch with the toughness many root modified plastic wire Financial Results from does not exist to be crushed, destroyed possible. 250kpa under pressure, the cross-sectional porosity remains above 60%, even if a large pressure is applied, there is always pass the water voids, and still 10-15% of the pores, and good resilience. The surface of the plastic blind ditch average opening rate of 90-95%, much higher than other similar products. The most effective collection of water seepage in the soil, and promptly brought together to drain away. Made of corrosion-resistant fiber membrane and modified polyethylene plastic blind ditch dimensional mesh combination, have the soil, the water never degradation advantages to be anti-aging formulations, maintain permanent material changes in the characteristics. Plastic blind ditch membrane can be chosen depending on the soil conditions, to fully meet the needs of the project, and to avoid the disadvantages of the old product membrane single. 5 plastic blind ditch the proportion of light, very easy to install on-site construction, construction efficiency is greatly accelerated.
