What is plastic drain blind ditch? What's the use?

The drainage plastic blind ditch is a plastic core with thermoplastic synthetic resin as the main raw material. After modification, in a hot melt state, thin plastic wire strips are extruded through the nozzle. Then the extruded plastic wire is fused on the joint by a molding device to form a three-dimensional porous material.The geotextile is wrapped around the main body as a filter membrane. There are four structural forms of porous rectangle, hollow rectangle, porous circle and hollow circle, with a variety of dimensions.Plastic blind ditch has the advantages of high surface opening rate, good water collection, large void ratio, good drainage, strong pressure resistance, good pressure resistance, good flexibility, good durability, light weight, convenient construction, greatly reduced labor intensity of workers, and high construction efficiency.

It is widely used in tunnel seepage and drainage, railway and road subgrade drainage, soft foundation construction, retaining wall filtration, slope and slope drainage, underground building drainage moisture, lawn drainage system, roof garden drainage, sewage treatment plant and landfill and other types of engineering, is widely welcomed by the engineering community.

1.The composition fiber of the plastic blind ditch is about 2mm wire strips, which are fused into a three-dimensional mesh body, and the principle is the same as the principle of the truss of the steel structure. The surface porosity is 95-97%, which is more than 5 times that of the porous tube and 3-4 times that of the resin mesh tube, and the surface water absorption is extremely high.

2.Because it is a three-dimensional structure, the voidage is 80-95%, the space and management are the same and light, the compression performance is more than 10 times stronger than the resin of the tube structure, therefore, even if it is compressed due to overload, but because it is a three-dimensional structure, the residual void is more than 50%, there is no problem of no water flow, and it is unnecessary to consider that it will be crushed by earth pressure.

3.The compressive strength is large, and the compression rate is less than 10% under 250KPa pressure.

4.With anti-aging agent, durable, underwater, soil in the medium place for decades to ensure stability.

5.Compressive and flexible, for bends and other bends can also be constructed, very lightweight, if the backfilling depth is about 10cm, can also be backfilled with bulldozers.

6.Due to the above characteristics, various problems in the traditional blind ditch in the past, such as uneven settlement or partial occlusion caused by overload, and the problem of no functional interruption caused by the gap being crushed, can be solved by plastic blind ditch materials.

7.Due to the use of hot melting molding without the use of binders, it will not cause collapse due to aging and stripping of binders.
