Three-Dimensional Composite Drainage Network

タイトルまたは説明

Composite drainage network (also known as three-dimensional geotechnical drainage board, tunnel drainage water board, discharge water board) by the three-dimensional structure of the plastic mesh-sided adhesive composition of seepage geotextile can be an alternative to traditional sand and gravel, mainly for landfill landfill, embankment and drainage tunnel wall.
In railways, highways and other transportation infrastructure, the safety and life of the project with its own drainage system was inextricably relations, including geosynthetic drainage system is an important component.
Three-dimensional composite drainage network is a new geosynthetics. Composition structure is a three-dimensional geonet core, both sides have a needle stick perforated nonwoven geotextile. Three-dimensional geonet core comprises a thick vertical ribs, as well as the top and bottom of each one inclined ribs. The discharge path can be quickly groundwater, there is a self-maintenance of the pore system that can block the capillary water under high loads. Meanwhile, it can also play the role of isolation and foundation reinforcement.
