Three dimensional composite drainage net

The composite drainage network is made of three-dimensional geonet double-sided bonded geotextile, which combines geotextile (reverse filter function) and geonet (drainage and protection function), providing "reverse filter-drainage-protection" effect. The three-dimensional structure of the composite drainage net core can withstand high compressive loads during the entire use process, and can maintain a considerable thickness, providing good water conductivity.

Product introduction

Features:
1. Laying between the foundation and the sub-base, it is used to drain the accumulated water between the foundation and the sub-base, block capillary water and effectively integrate into the edge drainage system. This structure automatically shortens the drainage path of the foundation, the drainage time is greatly shortened, and the use of foundation materials can be reduced (that is, materials with more fine materials and lower permeability can be used). Can prolong the service life of the road.
2. Laying drainage nets on the sub-base can prevent sub-base fine materials from entering the sub-base (that is, play an isolation role). The aggregate base will enter the upper part of the geonet to a limited extent. In this way, the composite geotechnical drainage network also has the potential to limit the lateral movement of the aggregate base. In this way, its function is similar to the reinforcement of the geogrid. Generally speaking, the tensile strength and rigidity of composite geo-drainage nets are superior to many geogrids used for foundation reinforcement, and this confinement will increase the support capacity of the foundation.
3. After the road is aging and cracks are formed, most of the rainwater will enter the section. In this case, the drainage grid is laid directly under the road surface instead of a drainable foundation. Drainage screens collect moisture before it enters the foundation/subbase. And it is also possible to wrap a layer of film at the bottom of the drainage net to further prevent moisture from entering the foundation. For rigid road systems, this structure allows roads to be designed with higher drainage coefficients Cd. Another advantage of this structure is the potential for more uniform hydration of the concrete (research into the extent of this advantage is ongoing). Whether it is for rigid roads or flexible road systems, this structure can prolong the service life of the road.
4. Under the northern climate conditions, the laying of drainage nets can help reduce the impact of frost heave. If the freezing depth is very deep, the geonet can be laid in a shallow position in the sub-base as a capillary block. It is also often necessary to replace it with a granular subbase that is not prone to frost heave, extending down to the freezing depth. The backfill soil that is prone to frost heaving can be directly filled on the drainage network until the foundation line. In this case, the system can be connected to a drainage outlet so that the groundwater table is at or below this depth. This would potentially limit the development of ice crystals, without limiting traffic loads during spring ice melt in colder regions.
