Drainage of Railway Tri-Dimensional Composite Geonets

Three dimensional composite drainage network is a new type of geosynthetics. Its structure is a three dimensional geonet core, and there are needle punched non woven geotextiles on both sides. The three dimensional geogrid core consists of a thick vertical rib and an inclined rib at the top and bottom, which can rapidly drain the around water from the road. 
It also has a pore maintenance system, which can block capillary water under high load. At the same time, it                                          
can also play the role of isolation and foundation reinforcement.
