Sensing type geogrid material and structure thereof
The invention relates to a sensing type geogrid material and a structure thereof. The sensing type geogrid material comprises a polymer matrix, the polymer matrix is added with carbon nanotubes and superconducting carbon black to serve as conductive filler, and the polymer matrix is high density polyethylene matrix, the carbon nanotubes account for 3%-7% of the total mass of the raw materials, and the superconducting carbon black accounts for 6%-14% of the total mass of the raw materials. The invention provides a manufacturing method of a high strength and high friction resistance sensing type geogrid, the geogrid of the type not only overcomes the problem of insufficient self-strength of traditional geogrids, but also utilizes the pull sensitive effect of conductive polymer composite materials, by detecting the electrical resistance change of the grid itself, deformation information of the grid and a reinforcing body can be obtained conveniently, and implantation of external sensors and other equipment is unnecessary, thereby avoiding disturbance to the reinforcing body and durability deficiency of the sensor itself. The sensing type geogrid material is suitable for deformation monitoring and safety early warning of geotechnical structures within a full life cycle.
