Nonmetal electrically conductive geotechnical cloth and composite drainage geonet

Abstract

The invention provides nonmetal electrically conductive geotechnical cloth and a composite drainage geonet. The nonmetal electrically conductive geotechnical cloth comprises geotechnical cloth and a nonmetal electrically conductive structure, wherein the nonmetal electrically conductive structure comprises one or a combination of carbon nano tubes, graphene and superconductive carbon black; the nonmetal electrically conductive structure can be an electrically conductive coating to be applied to the surface of the geotechnical cloth, can be electrically conductive fibers to be connected into the geotechnical cloth during making of the geotechnical cloth to form nonmetal electrically conductive blended geotechnical cloth, and can be electrically conductive sewing threads to sew the geotechnical cloth at certain intervals during making of the geotechnical cloth to form the nonmetal electrically conductive geotechnical cloth. The composite drainage geonet comprises a drainage geonet and the nonmetal electrically conductive geotechnical cloth bonded to one side or two sides of the drainage geonet. The problem that acid-base and electrochemical corrosion cannot be resisted due to the fact that metal is used as an electrically conductive material is solved.
