Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings:

[0014] A high-strength composite grid, comprising a finely woven high-density polyethylene material geotextile 1 and a steel-plastic composite tie-bar 2, the steel-plastic composite tie-bar 2 is woven into a grid-like grid, and the steel-plastic composite tie The finely woven high-density polyethylene material geotextile 1 is laid in the grid-shaped grid woven by the rib tape 2, and the finely woven high-density polyethylene material geotextile 1 and the steel-plastic composite reinforced tape 2 are connected by ultrasonic welding.

[0015] The finely woven high-density polyethylene material geotextile 1 is formed by warp and weft weaving of synthetic fiber bundles.

[0016] The steel-plastic composite reinforced tape 2 is made of steel wire 3 wrapped with high-density polyethylene 4.

[0017] The steel-plastic composite tie-bar 2 is made of steel wire 3 wrapped with ...

Abstract

The invention relates to a high-strength composite grid which comprises a finely-woven high-density polyethylene material geotextile (1) and plastics-steel bar strips (2). The plastics-steel bar strips (2) is woven into a lattice-shaped grid. The high-strength composite grid is characterized in that the finely-woven high-density polyethylene material geotextile (1) is laid in the lattice-shaped grid woven by the plastics-steel bar strips (2), and the finely-woven high-density polyethylene material geotextile (1) and the plastics-steel bar strips (2) are connected through ultrasonic welding. Through the mutual action of the finely-woven high-density polyethylene material geotextile and the grid woven by the plastics-steel bar strips, the invention enhances the mutual tensile strength and reduces the elongation and can also decrease the engineering workload in practical application.

Description

technical field [0001] The invention relates to the fields of pavement engineering and water conservancy engineering, in particular to a high-strength composite grid used for reinforcing pavement foundations and river embankments. Background technique [0002] At present, geogrids and geotextiles are widely used in the reinforcement of soft foundations such as railways and highways, and in engineering fields such as dams, river banks, slope protection, and road and bridge pavement enhancement treatments. With the continuous improvement of the quality requirements of these projects, the quality requirements for geotextiles and geogrids are also getting higher and higher. Ordinary geotextiles and geogrids have low strength and high elongation, so it is difficult to adapt to current engineering needs. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to invent a high-strength composite grid to overcome the above-mentioned defects. [0004] The techni...
