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.

A geocomposite with a geonet and a geotextile. The geotextile has a nonwoven fabric layer and a woven fabric layer, with the nonwoven fabric connected by needle-punching to the woven fabric whereby fibers of the nonwoven fabric extend through and beyond the woven fabric, and the woven fabric and fibers of the nonwoven fabric extending through the woven fabric are bonded to one side of the geonet.

A geonet having a length substantially greater than its width and including no more than first and second layers of strands. A first plurality of substantially parallel strands extends in the lengthwise direction and defines the first layer of strands, and a second plurality of substantially parallel strands is disposed on top of, and at an angle relative to, the first plurality of strands and defines the second layer of strands. The first and second plurality of strands are substantially incompressible and secured to one another at crossover locations. Geocomposites include geotextile bonded to at least one side of the geonet. The geonets / geocomposites are laid in geotechnical construction sites in the direction of expected drainage flow.

The invention provides an ecological restoration method of a slope. The ecological restoration method of the slope comprises the steps of smoothing the slope surface, paving geotechnical cloth on the smoothed slope surface and fixing the geotechnical cloth by use of an anchor rod, paving a honeycomb restraint system on the geotechnical cloth and fixing the honeycomb restraint system by use of an anchor rod, filling a plant growth substrate, paving a lawn nursery strip on the honeycomb restraint system, and nursing plants after paving is completed, wherein the honeycomb restraint system is composed of cells and reinforced belts passing through the cells; the lawn nursery strip comprises a geonet, setting paper, grass seeds, a slow release fertilizer and the setting paper, all of which are orderly paved from top to bottom; the ecological restoration method of the slope has the advantages that as the honeycomb restraint system is paved on the slope, the service life of the work can be greatly increased, the maintenance cost is reduced and the construction period is shortened, and the honeycomb restraint system is good in water permeability and moisture retention property, and capable of protecting soil from erosion by rainwater, and conserving and retaining soil; the method is short in construction period, convenient for maintenance, low in cost, capable of reinforcing the slope while restoring the ecology of the slope, and suitable for the soft foundation slopes of various gradients.
