Plastic Blind Ditch
Plastic blind ditch is a type of filter cloth wrapped by a plastic core. The plastic core is made of thermoplastic synthetic resin as the main raw material. After being modified, in the hot-melt state, a thin plastic wire is extruded through a nozzle, and the extruded plastic wire is welded at the node by a molding device to form a three-dimensional three-dimensional network structure. The plastic core has various structural forms such as a rectangle, a hollow matrix, and a circular hollow circle. This material overcomes the shortcomings of traditional blind trenches, has high surface open porosity, good water collection, large porosity, good drainage, strong pressure resistance, good pressure resistance, good flexibility, adapt to soil deformation, good durability , Light weight, convenient construction, workers' labor intensity is greatly reduced, and construction efficiency is high, so it is generally welcomed by the Engineering Bureau and has been widely used.
The products are mainly used for the drainage reinforcement of highway and railway subgrade shoulders; drainage for tunnels, subway underground passages and underground freight yards; soil and water conservation for hillside and slope development; vertical and horizontal drainage along various retaining walls; slippery ground and firepower Drainage of power plant ash piles and waste landfill projects; drainage of resting green spaces such as sports fields, golf courses, baseball fields, football fields, parks, roof gardens, flower terraces and etc; drainage of construction works for infrastructure projects; drainage of agricultural, horticultural underground irrigation, and low-lying wetlands System; drainage of site preparation works.
