Composite geotechnical drainage network Made of special three-dimensional geonet double-sided bonded geotextile. It combines geotextile (anti-filtration action) and geonet (drainage and protection action) to provide complete “anti-filtration drainage protection” effect. Three-dimensional composite drainage network It is a new geosynthetic material. The constituent structure is a three-dimensional geonet core with needle punched perforated non-woven geotextile glued on both sides. The three-dimensional geonet core includes one thick vertical rib, and one inclined rib each at the top and bottom. It can quickly drain groundwater from the road, and it also has a pore maintenance system, which can block capillary water under high load.
After the road ages and cracks form, most of the rainwater will enter the section. In this case, the three-dimensional Composite drainage network Laid directly under the pavement in place of a drainable foundation. Three-dimensional composite drainage network can be used when water enters the foundation /The sub-base layer is collected first. But also a film can be wrapped on the bottom end of the three-dimensional composite drainage net to further prevent moisture from entering the foundation. For rigid road systems, this configuration allows for higher drainage coefficients Cd To design the road. Another advantage of this structure is that it may allow concrete to be hydrated more uniformly (research on the extent of this advantage is ongoing). Whether for rigid roads or flexible road systems, this structure can prolong the service life of roads.
The composite geotechnical drainage net consists of a staple fiber needle-punched geotextile on both sides and a composite three-dimensional mesh core in the middle. Through machine heat sealing, the geotextile and the three-dimensional mesh core are heat sealed together to form a three-dimensional drainage network with a three-dimensional drainage structure. It can play the role of filtering and draining water. The three-dimensional composite drainage net consists of a layer of composite geomembrane and a layer of geotextile and a layer of three-dimensional mesh core compounded in the middle; Through machine heat sealing, the geotextile composite geomembrane and the three-dimensional mesh core are heat sealed together to form a three-dimensional waterproof and drainage structure drainage network, which is mainly used for subgrade drainage, and the composite geomembrane mainly plays a waterproof role.

At the same time, it can also play the role of isolation and foundation reinforcement. A new geosynthetic material. The three-dimensional composite drainage net is made of special three-dimensional geonet double-sided bonded geotextile. It combines geotextile (anti-filtration action) and geonet (drainage and protection action) to provide complete “anti-filtration drainage protection” effect. The unique three-dimensional structure of the three-dimensional composite drainage net core can withstand high compressive loads during the whole use process, and can maintain a considerable thickness, providing good hydraulic conductivity.
