Abstract
The utility model provides a warp knitting geogrid, which relates to the technical field of geosynthetics and is structurally characterized by comprising vertical grid strips 1 and transverse grid strips 2, wherein the vertical grid strips 1 and the transverse grid strips 2 are mutually staggered for forming a lattice-shaped structure, the connecting point parts are fixed by binding yarns 3, and the grid strips adopt high-intensity dacron industrial filaments. The warp knitting geogrid has the advantages that the intensity is high, the creep resistant performance is high, the strips on the surfaces of the woven grid strips are staggered, the contact area with the soil body is increased, the friction force is increased, the grid strips are in flexible structures and can be freely bent, folded and twisted without being damaged, the transportation and the carrying are convenient, the use is convenient, and the engineering manufacture price is saved.
Description
Technical field
The utility model relates to the geosynthetics technical field, relates to a kind of warp knitting geogrid particularly.
Background technology
In highway subgrade, side slope protection, dam construction are built; Often be employed in the method that adds geosynthetics in the soil body; Commonly used like GSZ, through the embedding of grid and soil block and the frictional force between anchoring and the grid and the soil body, strengthen the intensity of the soil body; And reaching the purpose of balanced sedimentation, it is used widely dragon in highway subgrade.In the prior art, the GSZ of laying the highway subgrade use mainly is a plastic grill, and plastic grill technology is simpler, cheap, and working strength is low, and long-time use just can show serious creep, causes the degeneration of structural stability.
Summary of the invention
The purpose of the utility model provides a kind of warp knitting geogrid, and both intensity was high, corrosion resistance is strong, easy to use again for it.
The task of the utility model realizes through following technical scheme.A kind of warp knitting geogrid comprises vertical grizzly bar, horizontal grizzly bar, and its design feature is to constitute fenestral fabric by some vertical grizzly bars and horizontal grizzly bar are interlaced, and its tie point place is fixed by bundled yarn, and said grizzly bar adopts high strength terylene industrial filament.
Its design feature is horizontal grizzly bar, vertically grizzly bar is formed by the braiding of three one thread bundles, and the grizzly bar after the braiding is through PVC slurry impregnation process.
The good effect of the utility model is: 1, intensity is high, creep-resistant property is strong.2, the grizzly bar striated surface that is woven into is staggered, has increased the contact surface with the soil body, has increased friction.3, grizzly bar is a flexible structure, can bend arbitrarily, reverse and not be destroyed, and is convenient to transportation, carrying, and is easy to use, saves construction costs.
Description of drawings
A kind of warp knitting geogrid sketch map that Fig. 1 the utility model provides.
The vertical grizzly bar of 1-among the figure, the horizontal grizzly bar of 2-, 3-bundled yarn.
The specific embodiment
Below in conjunction with accompanying drawing 1, the detail of a kind of warp knitting geogrid that the utility model is proposed details.A kind of warp knitting geogrid; Comprise vertical grizzly bar 1, horizontal grizzly bar 2; Become fenestral fabric by some vertical grizzly bars 1 with horizontal grizzly bar 2 mutual interlacings; Vertically the tie point place of grizzly bar 1 and horizontal grizzly bar 2 is fixing with bundled yarn 3 bindings, has improved the peel strength of node, makes grid integral body not yielding; Vertically grizzly bar 1, horizontal grizzly bar 2 are selected high-strength terylene industrial filament for use, and bundled yarn is selected polyester FDY filament for use, and vertically grizzly bar 1, horizontal grizzly bar 2 are placed to weave on the tricot machine by three one thread synnemas and form, and the grizzly bar grey cloth after the braiding is handled through PVC slurry impregnation technology again; The grizzly bar striated surface that is made into is staggered, has increased the contact surface with the soil body during use, has increased friction.The utlity model has that intensity height, creep-resistant property are strong, material is a flexible structure, the finished product after the braiding breaks into volume and is convenient to transportation, easy to use.
Claims (2)
