Chip stone blind trench and pebble blind trench which porosity is large

Blind ditch selection of plastic blind ditch pipe, save time and effort to save costs.

Plastic blind ditch is wrapped by the 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. The plastic core has various structural forms such as rectangular, hollow matrix, round hollow round and so on. The material overcomes the shortcomings of the traditional blind ditch, has a high rate of surface openings, good water collection, large void ratio, good drainage, compressive 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, the construction efficiency, and therefore by the Engineering Bureau of the general welcome, and has been widely used.
