Cross non woven fabric/ Cambrella Fabric

The application of geotechnical non-woven fabrics

Geotechnical non-woven fabric in the earthwork construction has four aspects: the basic function enhancement, filtering, isolation, channel. These four functions, under different circumstances, can use alone, also can have these functions at the same time. ( 1) Enhancement: like in reinforced concrete structure, steel bar as enhancement element, geotechnical non-woven fabrics is also enhanced components in the structure. By geotechnical non-woven fabric at the same time, the load can be distributed to a larger area, reduce the partial pressure, also enhanced. ( 2) Filtering: in geotechnical structure, the two different materials in isolation. For example in the grain layer of subgrade and foundation soil layer is set between geotechnical non-woven, can avoid the liquid under the action of force, up into the lower soil layer, or the upper stone sink into the soil layer, and allow freedom through the water. ( 3) Channel: this function only acupuncture geotechnical non-woven fabrics. Namely in geotechnical structure, the level of water or gas can be along the geotextile acupuncture non-woven guidance, and in small capillary action can be achieved under pressure. Because of these features, in geotechnical engineering is widely used in real use.
