Composite water-fast geotechnical cloth

Abstract

The invention provides a composite water-fast geotechnical cloth. The composite water-fast geotechnical cloth comprises base cloth, wherein a water-fast layer is arranged below the base cloth and is a polyurethane layer; supporting ribs are arranged below the water-fast layer and are a steel wire net horizontally laid below the water-fast layer; a second layer of base cloth is arranged below the supporting ribs and made of polyester; and an anti-corrosion layer is arranged below the second layer of base cloth and is a rubber layer. The water-fast layer is arranged below the base cloth, so the water absorption performance of the geotechnical cloth can be improved, a large amount of rainfall will not be directly leaked to the soil below, and the safety of a roadbed is guaranteed. The supporting ribs are arranged below the water-fast layer and can improve the strength of the geotechnical cloth, and the geotechnical cloth is not prone to cracking. A supporting frame is arranged around the supporting ribs and can further protect the supporting ribs and prevent the supporting ribs from sliding out of the geotechnical cloth to scratch the hands of operators, so the safety of the operators is guaranteed.

Description

technical field [0001] The invention relates to a geotextile, in particular to a composite water-resistant geotextile. Background technique [0002] In the early stage of road construction, roadbed needs to be laid. In the use of roadbed for fear of roadbed sinking, a large amount of geotextiles need to be used. Geotextiles are used during roadbed laying, so that the roadbed will not sink when it encounters precipitation. It is very serious and protects the safety of the roadbed. However, many roadbeds currently use a one-layer structure. Such a structure will reduce the quality of the geotextile. Once it encounters a strong acid roadbed, it will soon corrode the geotextile. Therefore, the geotextile with loopholes will have the risk of roadbed subsidence in the corresponding area, so that the seismic strength of the roadbed cannot be guaranteed, and it will also indirectly affect the service life of the road laid on the roadbed.
