Three-dimensional 3D composite drainage network
The filament composite drainage net
The filament composite drainage net is composed of a three-dimensional plastic net bonded with seepage geotextiles on both sides, which can replace the traditional sand and gravel layers, and is mainly used for drainage of landfills, roadbeds and inner walls of tunnels. The safety and service life of the filament composite geotechnical drainage network in the transportation infrastructure such as railways and highways are closely related to its own drainage system. Geosynthetics are an important part of the drainage system.
Filament composite drainage net is a new type of geosynthetic material. The constituent structure is a three-dimensional geonet core with needle-punched perforated non-woven geotextiles glued on both sides. The geonet core consists of one thick vertical rib and one diagonal rib at the top and bottom. It can quickly drain groundwater from the road, and it also has a pore maintenance system that blocks capillary water under high loads. At the same time, it can also play the role of isolation and foundation reinforcement. A new type of geosynthetic material.

The filament composite drainage net is made of a unique three-dimensional geonet double-sided bonded geotextile. Combining geotextile (reverse filtration) and geonet (drainage and protection), it provides a complete "reverse filtration-drainage-breathing-maintenance" comprehensive function, which is currently a more ideal drainage material.
Filament composite drainage net features:
1. Strong drainage (equivalent to one meter thick gravel drainage).
2. High tensile strength.
3. Reduce the probability of geotextiles embedded in the mesh core and maintain long-term stable drainage.
4. Accept high pressure load for a long time (can accept compressive load of about 3000Ka).
5. Corrosion resistance, acid and alkali resistance, long service life.
6. The construction is convenient, the construction period is shortened, and the cost is reduced. The unique three-dimensional structure of the composite drainage mesh core can withstand high compressive loads during the entire use process, maintain a considerable thickness, and provide good water conductivity.
