Three-dimensional composite drainage network

Three-dimensional drainage network (also known as three-dimensional geotechnical drainage plate, tunnel drainage plate, drainage plate) is composed of three-dimensional structure of plastic mesh double-sided bonded seepage geotextile, can replace the traditional sand and gravel layer, mainly used for landfill, subgrade and tunnel inner wall drainage

The safety and service life of railway, highway and other traffic infrastructure projects are closely related to their own drainage system, in which geosynthetic materials is an important part of the drainage system.

In railway, highway and other transportation infrastructure, the safety and service life of the project is closely related to its own drainage system, among which geosynthetic materials is an important part of the drainage system. The three - dimensional drainage network in drainage network is a new geosynthetic material. The constituent structure is a three-dimensional geomesh core with needle-punched non-woven geotextiles glued to both sides. The 3D geomesh core consists of a thick vertical rib and a diagonal rib at the top and bottom. It quickly drains groundwater from the road and has a pore-maintenance system that blocks capillary water at high loads. At the same time, it can also act as isolation and foundation reinforcement. A new type of geosynthetic material.
