AI Technical Summary
During the production and laying process, existing geotextiles are prone to be misaligned with the anti-seepage membrane due to stress, resulting in local water seepage.
A reinforced structure is provided between the geotextile and the anti-seepage film, including a butt protrusion and a docking groove. The contact area is increased by the matching of the docking protrusion and the docking groove, thereby improving tensile resistance and preventing misalignment.
The connection strength between the geotextile and the anti-seepage film is enhanced, the misalignment during laying is avoided, and the anti-seepage effect is improved.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a high-strength anti-seepage geotextile includes an anti-seepage membrane 3, an upper geotextile 1 is covered on the upper layer of the anti-seepage membrane 3, a lower geotextile 2 is covered on the lower layer of the anti-seepage membrane 3, and a strengthening structure is provided between the upper geotextile 1, the lower geotextile 2 and the anti-seepage membrane 3, and the strengthening structure is used to improve the tensile performance of the geotextile;
[0019] The strengthening structure includes docking projections 4 integrally formed on the upper and lower surfaces of the anti-seepage membrane 3, and the strengthening structure further includes docking grooves 5 formed on the mutually approaching surfaces of the upper geotextile 1 and the lower geotextile 2;
[0020] The outer wall of the docking projection 4 is fitted with the inner wall of the docking groove 5.
[0021] In this embodiment: The upper geotextile 1 and the lower geotextile 2 are both formed by warp and weft knitting with synthetic fibers such as nylon, polyester, polypropylene, and polyethylene. During the knitting process, by means of hot pressing, docking grooves 5 are formed on one side of the upper geotextile 1 and the lower geotextile 2. And on the forming die of the anti-seepage membrane 3, a cavity for forming the docking protrusion 4 is formed. After the upper geotextile 1, the lower geotextile 2, and the anti-seepage membrane 3 are produced, they are docked to form an anti-seepage geotextile. After docking, the docking protrusion 4 is located in the docking groove 5, which increases the docking area between the upper geotextile 1, the lower geotextile 2, and the anti-seepage membrane 3. During the laying process, the docking protrusion 4 and the docking groove 5 in the occluded state form mutual pulling forces, forming a certain limiting force, avoiding the dislocation of the upper geotextile 1 or the lower geotextile 2 caused by external forces during the laying process, thus achieving a strengthening effect.
[0022] Please refer particularly to Figure 2 and Figure 3 , the number of docking protrusions 4 located above and below is multiple. In a group, multiple docking protrusions 4 are equidistantly distributed axially. The number of docking grooves 5 located above and below is multiple. In a group, multiple docking grooves 5 are equidistantly distributed axially.
[0023] In this embodiment: The docking protrusions 4 and the docking grooves 5 that are equidistantly distributed axially can be docked and occluded with each other, and the state of multiple equidistant distributions can further increase the contact area and the limiting force between the upper geotextile 1, the lower geotextile 2, and the anti-seepage membrane 3.
[0024] Please refer particularly to Figure 2 and Figure 3 , the distance between two adjacent docking protrusions 4 axially is equal to the distance between two adjacent docking grooves 5 axially.
[0025] In this embodiment: This design method can achieve one-to-one docking of the docking protrusion 4 and the docking groove 5, avoiding dislocation.
[0026] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
