Description

Technical field:

[0001] The utility model belongs to the technical field of geotextiles, and more specifically relates to a geotextile assembly for road paving. Background technology:

[0002] Geotextile is a widely used geosynthetic material. It is widely used in railway roadbed reinforcement, highway pavement maintenance, sports halls, dam protection, hydraulic construction isolation, tunnels, coastal beaches, environmental protection and other projects. Geotextile, also known as geotextile, is a permeable geosynthetic material woven from synthetic fibers. Geotextile is one of the new geosynthetics. The finished product is in the form of cloth, generally 4-6 meters wide and 50-100 meters long.

[0003] The connection process during the construction of geotextile pavement is usually overlapped, stitched and welded. The width of stitching and welding is generally more than 0.1m, and the overlap width is generally more than 0.2m. Among the above connection methods, the overlap process is just a superposition of multiple pieces of geotextiles, which has slippage and is only suitable for construction scenes with low requirements; the stitching process is time-consuming and labor-intensive, and the sewn geotextile is large and difficult to lay; the welding process requires large equipment and has high requirements for the construction environment. Utility model content:

[0004] In order to solve the above problems and overcome the shortcomings of the prior art, the utility model provides a geotextile assembly for road paving;

[0005] The first technical problem to be solved is: there are several existing geotextile connection processes. The overlapping process is just multiple pieces of geotextiles superimposed on each other, which causes slippage and is only suitable for construction scenarios with low requirements; the sewing process is time-consuming and labor-intensive, and the geotextile after sewing is larger and difficult to lay; the welding process requires large equipment and has high requirements for the construction environment.

[0006] The specific technical solution of the utility model to solve the above technical problems is as follows: the geotextile assembly for road paving comprises a geotextile body; the characteristics are as follows: rubber belts are sewn on the edges of the four sides of the geotextile body, air holes are evenly opened on the rubber belts in the horizontal direction or in the vertical direction, and Velcro for connecting multiple geotextile bodies to increase the width is also provided on both sides of the geotextile body in the horizontal direction or in the vertical direction;

[0007] Connecting reinforcing yarns are evenly woven in along the warp weaving direction of the geotextile body.

[0008] Furthermore, the warp yarns and weft yarns of the geotextile body are arranged vertically.

[0009] Furthermore, the reinforcing yarn is intertwined with every other weft yarn, and the reinforcing yarn and the weft yarn are intertwined in a plain weave state.

[0010] Furthermore, the Velcro includes a Velcro hook surface and a Velcro fleece surface.

[0011] Furthermore, the Velcro hook surface at the head end of one geotextile body is connected to the Velcro fleece surface at the tail end of an adjacent geotextile body.

[0012] The beneficial effects of the utility model are:

[0013] One advantage of the utility model is that it provides: the connection is made through the Velcro hook surface at the head end of the geotextile body and the Velcro fleece surface at the tail end of the geotextile body, and the eyelet holes are used to facilitate the extension of the geotextile body in width and depth;

[0014] One advantage of the utility model is that: rubber belts are sewn on the edges of the geotextile body to improve the stability of the overall laying of the geotextile and prevent slippage. By evenly arranging air holes on the rubber belt, the geotextile body can be easily connected in different directions, and the structural stability of the air holes is increased, the anti-tear ability is strong, and the service life is extended.

[0015] One advantage of the utility model is that it provides: in the warp weaving direction of the geotextile body, reinforcing yarns are evenly woven into the geotextile body, thereby improving the wear resistance of the geotextile body and reducing deformation and wrinkles of the geotextile body due to external forces.
