[0019] In the following description, embodiments of the snap-fit ​​geogrid overlap structure of the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-4This invention illustrates a snap-fit ​​geogrid overlap structure according to an embodiment of the present invention, including pressure strips 2 located at the overlap positions of two geogrid meshes 1. Three fastening components 3 are provided on the surface of the pressure strips 2. Each fastening component 3 includes a lower clamping plate 31, with an upper clamping plate 32 covering the top of the lower clamping plate 31. Elastic locking blocks 4 are integrally injection molded on both the front and rear sides of the top of the lower clamping plate 31. Rectangular slots 2 5 are provided on both the front and rear sides of the upper clamping plate 32. The elastic locking blocks 4 engage with the inner cavity of the rectangular slots 2 5, and are secured by elasticity. The combined use of the locking block 4 and the rectangular locking groove 5 allows the upper clamping plate 32 to be stably fastened to the top of the lower clamping plate 31, thereby securing the overlap of the two geogrid meshes 1. Anti-slip pressure plates 6 are fixedly connected to the front and rear sides of the bottom of the upper clamping plate 32, and anti-slip grooves 7 are fixedly connected to the front and rear sides of the top of the lower clamping plate 31. The geogrid mesh 1 is located between the anti-slip pressure plates 6 and the anti-slip grooves 7. Fixed... Positioning tube 8 and positioning sleeves 9 are fixedly connected to both sides of the top of the lower clamping plate 31. The positioning tube 8 is inserted into the inner cavity of the positioning sleeve 9. The U-shaped anchor 34 is simultaneously inserted into the inner cavities of the positioning tube 8 and the positioning sleeve 9. Through the cooperation of the positioning tube 8 and the positioning sleeve 9, the lower clamping plate 31 and the upper clamping plate 32 are connected and aligned, so that the lower clamping plate 31 and the upper clamping plate 32 can be stably fastened to the surface of the geogrid 1. At the same time, through holes are reserved for the U-shaped anchor 34 to ensure the overlap of the two geogrids 1. The position is fixed, and the geogrid 1 is located between the lower clamping plate 31 and the upper clamping plate 32. The top of the upper clamping plate 32 is provided with a rectangular slot 33 that matches the pressure strip 2. A U-shaped anchor 34 is provided through the top of the upper clamping plate 32. Multiple anti-detachment spikes 10 are fixedly connected to both sides of the surface of the U-shaped anchor 34. The top of the pressure strip 2 is provided with a through hole 35 that matches the U-shaped anchor 34. The bottom end of the U-shaped anchor 34 passes through the through hole 35, the upper clamping plate 32 and the lower clamping plate 31 in sequence and is inserted into the soil.

[0021] Working principle: In use, the user overlaps two geogrids 1, ensuring the overlap length is approximately 30cm. The user then moves the lower clamping plate 31 through the holes in the geogrid 1 to its bottom. Next, the upper clamping plate 32 is clamped onto the top of the lower clamping plate 31 from top to bottom. The elastic locking block 4 deforms under the pressure of the upper clamping plate 32 until it is stably engaged within the rectangular slot 5, thus securing the lower clamping plate... 31 and the upper clamping plate 32 are fixed to the surface of the geogrid 1, and the overlapping positions of the two geogrids 1 are fastened. Then, the user clamps the pressure strip 2 into the inner cavity of the rectangular slot 33, and inserts the U-shaped anchor 34 from top to bottom, so that the elastic block 4 is inserted into the inner cavity of the positioning tube 8 and the positioning sleeve 9 until the U-shaped anchor 34 is fully inserted into the slope, and the pressure strip 2, the lower clamping plate 31 and the upper clamping plate 32 are fixed, so that the two geogrids 1 can be installed firmly.

[0022] In summary, this snap-fit ​​geogrid overlap structure, through the setting of the snap-fit ​​component 3, pre-connects the overlap positions of the two geogrid meshes 1, and then, with the cooperation of the pressure strip 2 and the snap-fit ​​component 3, presses and fixes the connection positions of the two geogrid meshes 1 to the slope, thereby achieving the purpose of quick connection and assembly and secure and reliable installation.
