Abstract

The invention discloses an interlayer net enhanced type needle punched geotextile. The upper surface of a textile body is provided with transverse reinforcing ribs and longitudinal reinforcing ribs, arectangular grid is defined by the transverse reinforcing ribs and the longitudinal reinforcing ribs in a criss-cross mode, textile wires are arranged in the rectangular grid, a gap is formed betweenevery two adjacent textile wires, the transverse reinforcing ribs and the longitudinal reinforcing ribs on the upper surface of the textile body are provided with convex points, the sections of the convex points are in a semicircle shape, the lower end of a first textile layer is provided with a first interlayer net, the first interlayer net is provided with meshes, the lower end of a second interlayer net is provided with a third textile layer, the surface of the lower end of the third textile layer is provided with transverse reinforcing ribs and longitudinal reinforcing ribs, the textile body is provided with a support, and the support is fixed to the periphery of a water flow groove. The interlayer net enhanced type needle punched geotextile is combined with an existing device for creative design, is higher in strength and has hydrophobicity.

Description

technical field [0001] The invention relates to a geotextile, in particular to a mesh-reinforced needle-punched geotextile. Background technique [0002] my country's geotextiles started in the early 1980s, but the amount used was very small at that time, and it was only an experimental application. It was not until the catastrophic flood in 1998 that the government paid attention to it, and the construction department included the application of geotextiles in the design specifications, and formulated relevant national standards, so that geotextiles were really valued and developed. At present, the amount of geotextiles in my country has exceeded 300 million m2, and non-woven geotextiles account for about 40% of the total. my country's civil engineering construction has a huge potential market, and its potential is by no means lower than the 700-800 million m2 used in the United States. Experts estimate that my country's geotextiles will continue to grow at double digits ...
