Plastic Blind Trench

Plastic blind ditch is wrapped by plastic core outside the filter cloth group type.

Plastic blind ditch is wrapped by plastic core outside the filter cloth group type. Plastic core is a thermoplastic synthetic resin as the main raw material, after modification, in the hot melt state, through the nozzle extrusion of fine plastic filaments, and then through the molding device will be extruded plastic filaments in the junction of the fusion, the formation of three-dimensional three-dimensional mesh structure. At present, the plastic core has a variety of structural forms such as rectangular, hollow matrix, round hollow round. The material overcomes the shortcomings of the traditional blind ditch, with high surface open porosity, good water collection, large void ratio, good drainage, strong compression resistance, good pressure resistance, good flexibility, adapt to the deformation of the soil, good durability, light weight, easy construction, workers' labor intensity is greatly reduced, high construction efficiency, and thus generally welcomed by the Engineering Bureau and widely used.

Plastic blind ditch characteristics

1, the composition of the plastic blind ditch fiber for 2mm or so, mutual joints fused to form a three-dimensional mesh body, the principle of the truss with the steel structure of the building the same principle. The surface of the open hole shelter is 95-97%, is more than 5 times of the perforated pipe, is 3-4 times of the resin grid pipe, the surface water absorption rate is very high.

2、Because it is three-dimensional structure, the void rate is 80-95%, the composition of space and management of the same and lightweight, compressive performance than the tube structure of the resin is more than 10 times stronger, so even if the overload is pressed, but because it is a three-dimensional structure, so the residual void is also up to 50% or more, there is no water problems, no need to consider the earth pressure will be crushed.

3, compressive strength, 250KPa pressure, its compression rate is less than 10%.

4, with anti-aging agent, durable, underwater, soil and so on into the place for decades can ensure stability.

5, pressure and flexible, for curved roads and other curved position can also be constructed, very lightweight, if the backfill depth of 10cm or so, can also be backfilled with bulldozers.

6、Because of the above characteristics, so the traditional blind ditch appeared in the past a variety of problems, such as uneven settlement or due to overloading caused by part of the occlusion, was crushed leading to the void caused by the interruption of the function of the whole, can be solved through the plastic blind ditch material.

7、Because it is molded by hot melting without using binder, so it will not collapse due to aging and peeling of binder.
