Description

Technical Field

[0001] This utility model relates to the field of geocells, specifically a high-strength composite geocell. Background Technology

[0002] Geocells, as a type of geosynthetic material with significant reinforcement and strengthening functions, can efficiently distribute and transfer vertical loads thanks to their specific height structural design. This material can promote the transfer of failure slip lines on the surface of the foundation and subgrade to deeper soil layers, thereby forming a "deep foundation" effect and fundamentally reducing the probability of uneven settlement problems.

[0003] In the existing technology, traditional geocells are made of a single polymer material, have a single-layer grid structure, a large grid size, and are produced by extrusion molding followed by welding or bonding. They are used in environments with conventional load distribution.

[0004] However, traditional geocells are prone to deformation and have limited recovery capacity when subjected to large loads, and the connection force of the fastening parts is relatively small, making geocells unsuitable for projects with large loads and high durability requirements. Therefore, this utility model proposes a high-strength composite geocell to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength composite geocell to solve the problems mentioned in the background art.

The lower end of the fixing plate is inserted into the ground by fixing nails, and the upper end of the fixing plate is fixed by fixing caps. Fasteners are provided at the inner end of the geocell.

[0008] Preferably, the fixing cap is U-shaped and made of elastic metal. Two fixing protrusions are installed on the symmetrical sides inside the fixing cap, and the lower end of the fixing protrusions is provided with a guide slope.

[0009] Preferably, the fixing plate has symmetrical grooves with corresponding fixing protrusions on its left and right sides. When the fixing cap is snapped onto the upper end of the fixing plate, the fixing protrusions are inserted into the grooves.

[0010] Preferably, protrusions are fixedly installed on the outer sides of both the left and right ends of the fixing plate, and a sliding groove is provided on one side of the protrusion. Slider blocks are fixedly installed on both the left and right sides of the fastener. Both the slider and the sliding groove are isosceles trapezoidal, and the slider can be slidably inserted into the sliding groove.

[0011] Preferably, the fixing nail is fixedly installed at the end of the fixing plate away from the fixing cap, and the end of the fixing nail away from the fixing plate is inserted into the ground.

[0012] Preferably, a rubber pad is fixedly installed on the inner side of the fixing plate.

[0013] Preferably, the cell strip comprises a polyester strip, which is covered with a PE sheet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention involves splicing several geocell strips laid on the ground, clamping and fixing them with connecting components, inserting fixing caps at the top of the fixing plate after fixing to prevent the geocell strips from slipping, and then inserting fasteners into the spliced ​​geocells and fixing them to the side wall of the fixing plate to enhance the strength of the geocells, enabling them to withstand larger loads and meet the requirements of projects with high durability.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1-4This utility model provides a technical solution: a high-strength composite geocell, comprising: a plurality of geocell strips 1, with adjacent geocell strips 1 connected by connecting components 2 to form a honeycomb-like geocell. The geocell forms a honeycomb-like three-dimensional confinement system, which can significantly improve the performance of ordinary filling materials in load-bearing and corrosion-resistant applications over a wide range.

[0023] The connecting component 2 includes a fixing plate 5, which is U-shaped. The connection point of two adjacent geocell strips 1 is located inside the fixing plate 5. A rubber pad 8 is fixedly installed on the inner side of the fixing plate 5. The rubber pad 8 increases the friction between the geocell strip 1 and the fixing plate 5, thereby preventing sliding displacement between the geocell strip 1 and the fixing plate 5. A fixing nail 7 is fixedly installed at the end of the fixing plate 5 away from the fixing cap 3. The end of the fixing nail 7 away from the fixing plate 5 is inserted into the ground. The fixing nail 7 fixes the fixing plate 5 to the ground and fixes the geocell strip 1, preventing displacement of the geocell strip 1 when soil is poured on it. The upper end of the fixing plate 5 is fixed by the fixing cap 3. A fastener 9 is provided at the inner end of the geocell. Protrusions are fixedly installed on the outer sides of both ends of the fixing plate 5. A groove 6 is opened on one side of the protrusion. Slider blocks are fixedly installed on both sides of the fastener 9. The slider and the groove 6 are both isosceles trapezoidal. The slider can slide into the groove 6 to strengthen the geocell.

[0024] Specifically, several geocell strips 1 are laid on the ground and spliced ​​together, then fixed by connecting components 2. Fasteners 9 are then inserted into the spliced ​​geocell and fixed to the side wall of the fixing plate 5 to fix and reinforce the geocell, so that it can adapt to larger loads and meet the requirements of projects with high durability.

[0025] Example 2, as Figure 1 , Figure 2 and Figure 4 As shown, based on Embodiment 1: the fixing cap 3 is U-shaped and made of elastic metal. Two fixing protrusions 12 are installed symmetrically on the inside of the fixing cap 3. The lower end of the fixing protrusions 12 is provided with a guide slope. The fixing cap 3 undergoes elastic deformation through its own stretching, which facilitates the insertion of the fixing protrusions 12 into the outside of the fixing plate 5. The left and right sides of the fixing plate 5 are symmetrically provided with grooves 4 corresponding to the fixing protrusions 12. When the fixing cap 3 is snapped into the upper end of the fixing plate 5, the fixing protrusions 12 are inserted into the grooves 4, thereby fixing the fixing cap 3 to the outside of the fixing plate 5.

[0026] Specifically, after inserting the two cell strips 1 into the fixing plate 5, the fixing cap 3 is snapped onto the upper end of the fixing plate 5. Under the action of the guide break, the fixing protrusion 12 applies an external supporting force to the fixing cap 3, thereby allowing the fixing protrusion 12 to slide on the outside of the fixing plate 5 until the fixing protrusion 12 moves to the outside of the groove 4. Under the rebound force of the fixing cap 3, the fixing protrusion 12 is inserted into the groove 4, thereby fixing the fixing cap 3 on the outside of the fixing plate 5 and preventing the cell strips 1 from sliding out.

[0027] Implementation Case 3, such as Figure 3 As shown, based on Embodiment 1, the cell strip 1 includes a polyester strip 11, which is covered with a PE sheet 10.

[0028] Specifically, polyester, also known as polyester fiber, has high strength and elastic recovery, making the cell strip 1 sturdy and durable. PE sheet 10, also known as polyethylene, has good corrosion resistance and water resistance. When wrapped around the polyester strip 11, it can give the cell strip 1 good water resistance and corrosion resistance, which can greatly increase its service life underground.

[0029] In actual use, several geocell strips 1 are laid on the ground and spliced ​​together, and clamped and fixed by connecting components 2. After fixing, fixing caps 3 are inserted into the upper end of fixing plate 5 to prevent geocell strips 1 from slipping. After fixing, fixing nails 7 are inserted into the ground to prevent the geocell from shifting relative to the ground due to the rebound of the geocell strips 1. Then, fasteners 9 are inserted into the spliced ​​geocell and fixed to the side wall of fixing plate 5 to enhance the strength of the geocell. The geocell strips 1 are composed of polyester strips 11 wrapped with PE sheets 10. The polyester strips 11 themselves have high strength, and the wrapped PE sheets 10 have good waterproof and corrosion resistance. The above structure enables the geocell to adapt to large loads and meet the requirements of projects with high durability.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
