Description

Technical Field

[0001] This utility model relates to the field of geotextile technology, specifically to a crack-resistant composite geotextile. Background Technology

[0002] During the laying process, multiple rolls of geotextile often need to be spliced ​​on-site to form a continuous whole. Currently, the most widely used splicing method is to use a geotextile edge sealing machine to sew the edges of two pieces of geotextile together. Generally, one worker will first attach the edges of the two pieces of geotextile together, while another worker will use the edge sealing machine to sew them together.

[0003] Because geotextiles are soft and easily deformed, and especially in windy conditions during construction, it is extremely difficult for workers to stably align and adhere two pieces of geotextile. This makes sewing difficult, often resulting in uneven and non-straight seams, with crooked stitches, inconsistent tension, or wrinkles at the joints. These uneven stress points create stress points at the seams. When the project is put into use and the geotextiles are subjected to tensile forces from fill soil and foundation deformation, these weak points caused by uneven sewing will experience severe stress concentration, leading to cracks or tears in the spliced ​​geotextiles at the seams, ultimately causing the joint to fail. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a crack-resistant composite geotextile.

[0005] The technical solution of this utility model is as follows: A crack-resistant composite geotextile includes a geotextile body, one side of which is a sewn side. A connecting unit is provided on the upper or lower surface of the sewn side along its length. The connecting unit includes a strip-shaped reinforcing mesh and a fastener. The reinforcing mesh is thermally melt-bonded with the geotextile body. The fastener is bonded to the side of the reinforcing mesh away from the geotextile body. The fastener includes a base strip and male and female fasteners disposed thereon. The male and female fasteners are arranged side by side and spaced apart.

[0006] To facilitate workers to quickly and neatly fold up and attach the two geotextile bodies along their sewn sides, the edge of the sewn side is called the sewn edge. The geotextile body has pleats, which are located on the side of the reinforcing mesh away from the sewn edge. The length direction of the pleats is consistent with the length direction of the reinforcing mesh.

[0007] Furthermore, the vertical spacing between the pleats and the reinforcing mesh is set to be less than the minimum vertical spacing between the reinforcing mesh and the seam edge.

[0008] Preferably, the reinforcing mesh is made of high-strength polyester or glass fiber.

[0009] To enhance the connection strength at the fastener points of the geotextile and reduce cracking or tearing, the width of the reinforcing mesh is 1-5 cm wider than the width of the fastener. The wider reinforcing mesh can improve the tensile strength of the geotextile at the seam.

[0010] The structure of the hook and loop fastener is as follows: the male hook is the hook of the Velcro strap, and the female hook is the loop of the Velcro strap.

[0011] To facilitate the uniform orientation of the two geotextile pieces after sewing and make them easier to lay, a male adhesive tape is provided along the length of the sewing side near the sewing edge. The male adhesive tape is located on the opposite side of the reinforcing mesh. The sewing side is also provided with a female adhesive tape that matches the male adhesive tape. The female adhesive tape is located on the side of the fold away from the sewing edge.

[0012] The adhesive male tape and adhesive female tape are structured as follows: the adhesive male tape includes a first connecting tape and a plurality of adhesive male pieces disposed thereon and spaced apart; the adhesive female tape includes a second connecting tape and a plurality of adhesive female pieces disposed thereon; the length directions of the first connecting tape and the second connecting tape are the same.

[0013] Furthermore, the length direction of the male adhesive piece is consistent with the length direction of the first connecting strip, and the length direction of the female adhesive piece is perpendicular to the second connecting strip.

[0014] The beneficial effects of this utility model are as follows: The combination of fasteners and reinforcing mesh enables rapid pre-positioning and crack resistance enhancement of geotextiles. The hooks and loops arranged side by side in the fasteners allow the two geotextiles to be stably aligned before sewing. That is, the hooks of one geotextile body are bonded to the loops of the other geotextile body, effectively avoiding displacement caused by wind or operational factors, ensuring that the sewing line is straight and uniform, and reducing the risk of stress concentration caused by the bending of the sewing line.

[0015] The reinforcing mesh is integrated with the geotextile body through a hot-melt composite method to form an integral load-bearing structure. Its width is greater than that of the fastener, which expands the stress area and can effectively disperse the concentrated tensile force in the sewn area to a larger area of ​​the geotextile body, thereby improving the tensile strength and tear resistance at the joint.

[0016] The pleats serve as pre-folding guide lines, enabling construction workers to quickly and neatly gather the seam edges, thus improving the efficiency of the connection. Attached Figure Description

[0018] See Figure 1 , Figure 2 and Figure 3 As shown, a crack-resistant composite geotextile includes a geotextile body 1. One side of the geotextile body 1 is a sewn side 101. Connecting units are provided along the length of the upper or lower surface of the sewn side 101. Each connecting unit includes a strip-shaped reinforcing mesh 2 and a fastener 3. The reinforcing mesh 2 is thermally fused to the geotextile body 1. The fastener 3 is bonded to the side of the reinforcing mesh 2 away from the geotextile body 1. The fastener 3 includes a base strip 301 and overlapping male buckles 302 and female buckles 303 disposed thereon. The overlapping male buckles 302 and female buckles 303 are arranged side-by-side and spaced apart. The overlapping male buckle 302 is a hook of a Velcro strap, and the overlapping female buckle 303 is a loop of a Velcro strap. By using the Velcro strap, two geotextile bodies 1 can be quickly pre-connected, forming a uniform sewn area and reducing errors from manual bonding or the influence of wind speed.

[0019] The edge of the sewn side 101 is the sewn edge 102. The geotextile body 1 has pleats 103, which are located on the side of the reinforcing mesh 2 away from the sewn edge 102. The length direction of the pleats 103 is consistent with the length direction of the reinforcing mesh 2. The pleats 103 facilitate workers in quickly and neatly folding up and fitting the sewn sides 101 of the two geotextile bodies 1 together. The pleats 103 serve as pre-folding guide lines, enabling construction workers to quickly and neatly fold up the edge of the sewn edge 102, improving docking efficiency and operational standardization. The vertical distance between the pleats 103 and the reinforcing mesh 2 is less than the minimum vertical distance between the reinforcing mesh 2 and the sewn edge 102, providing sufficient sewing space for the sewn side 101 and facilitating the operation of the sewing machine.

[0020] The reinforcing mesh 2 is made of high-strength polyester or glass fiber. To enhance the connection strength at the fastener 3 location on the geotextile body 1 and reduce cracking or tearing, the width of the reinforcing mesh 2 is 1-5 cm wider than the fastener 3. This wider reinforcing mesh increases the tensile strength of the geotextile body 1 at the seam side 101. The reinforcing mesh 2 forms an integral load-bearing structure with the geotextile body 1 through hot-melt bonding or other methods. Its wider design than the fastener 3 expands the stress-bearing area, effectively distributing the concentrated tensile force in the seam area to a larger area of ​​the geotextile body 1, thus improving the tensile strength and tear resistance at the joint.

[0021] To ensure the two geotextile pieces are uniformly oriented to one side after sewing, facilitating laying, a male adhesive tape 4 is provided along the length of the sewing side 101 near the sewing edge 102. The male adhesive tape 4 is positioned on the opposite side of the reinforcing mesh 2. A female adhesive tape 5, compatible with the male adhesive tape 4, is also provided on the sewing side 101, positioned on the side of the fold 103 away from the sewing edge 102. Both the male adhesive tape 4 and the female adhesive tape 5 are bonded to the geotextile body 1. This directional bonding design of the male adhesive tape 4 and the female adhesive tape 5 ensures that the free edges are firmly attached to the surface of the geotextile body after sewing, guaranteeing a smooth overall laying surface, preventing edge curling, and comprehensively improving construction quality and long-term reliability.

[0022] The structure of the male adhesive tape 4 and the female adhesive tape 5 is as follows: the male adhesive tape 4 includes a first connecting tape 401 and a plurality of male adhesive pieces 402 disposed thereon and spaced apart; the female adhesive tape 5 includes a second connecting tape 501 and a plurality of female adhesive pieces 502 disposed thereon. The length directions of the first connecting tape 401 and the second connecting tape 501 are the same. In this embodiment, the male adhesive piece 402 is a hooked male piece of Velcro, and the female adhesive piece 502 is a fuzzy female piece of Velcro. The male adhesive piece 402 and the female adhesive piece 502 can be quickly bonded together. The operator of the hand-held edge sealing machine can easily connect the male adhesive piece 402 to the female adhesive piece 502 by bending the geotextile at the fold 103 on the sewn side 101. The vertical distance from the first connecting tape 401 to the fold 103 is the same as the vertical distance from the second connecting tape 501 to the fold 103.

[0023] To improve the tolerance of the bonding between the male adhesive piece 402 and the female adhesive piece 502, the length direction of the male adhesive piece 402 is consistent with the length direction of the first connecting strip 401, and the length direction of the female adhesive piece 502 is perpendicular to the second connecting strip 501. This allows the male adhesive piece 402 to be quickly pre-bonded to the female adhesive piece 502 without the need to spend time aligning the corresponding male adhesive piece 402 and female adhesive piece 502.
