Description

Technical Field

[0001] The utility model relates to the technical field of geocells, in particular to an overlapping geocell. Background Art

[0002] In the field of civil engineering, geocells, as an important geosynthetic material, are widely used in foundation reinforcement, slope protection, soil stabilization, etc. in projects such as roads, railways, water conservancy, and environmental protection. The traditional geocell structure is mostly formed by connecting single or multiple geocell sheets through welding, stitching, etc. to form a grid system with a three-dimensional spatial structure. However, this traditional connection method often has problems such as insufficient connection strength, easy damage, and low construction efficiency in complex and changeable engineering environments.

[0003] Specifically, the node connections of traditional geocells often use simple welding or stitching techniques. These connection methods are prone to breakage or detachment when subjected to external forces, resulting in a decrease in the overall stability of the geocells. In addition, the welding and stitching processes require professional equipment and operating skills, which not only increase the construction difficulty and cost but also limit the construction efficiency. Summary of the Invention

[0004] The purpose of the utility model is to provide an overlapping geocell to solve the technical problem that in traditional geocells, when subjected to external forces, the nodes are prone to breakage or detachment, resulting in a decrease in the overall stability of the geocells.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: to provide an overlapping geocell, which includes:

[0006] A first geocell sheet and a second geocell sheet, the first geocell sheet and the second geocell sheet are respectively folded back to form folded-back ends, and the folded-back ends of the first geocell sheet and the second geocell sheet overlap each other;

[0007] And a connecting device arranged at the overlapping part of the first geocell sheet and the second geocell sheet; the connecting device connects the first geocell sheet and the second geocell sheet to form a cell node.

[0008] In one embodiment, a limiting member is arranged inside the folded-back end.

[0009] In one embodiment, the shape of the limiting member can be any one of rod-shaped, sheet-shaped, ring-shaped, or U-shaped.

[0010] In one embodiment, the folded-back end is provided with holes or slits for facilitating the installation of the connecting device.

[0011] In one embodiment, the connecting device can be any one of a clip bolt structure, a clip riveting structure, a U-shaped nail weaving structure, and a sewing structure.

[0012] In one embodiment, the limiting member is connected to the connecting device

[0013] In one embodiment, the clip bolt structure includes:

[0014] A pair of clips, which are respectively located on both sides of the overlapping part of the first cell sheet and the second cell sheet;

[0015] A threaded member, which is arranged on the clip, and the threaded member locks the clip to clamp and fix the overlapping part of the first cell sheet and the second cell sheet.

[0016] In one embodiment, the edge of the clip is arc-shaped.

[0017] One or more of the above technical solutions in the embodiments of the present invention have at least the following technical effects or advantages:

[0018] High-strength connection: Through the overlapping connection method and diverse connecting devices (such as clip bolt structure, clip riveting structure, U-shaped nail weaving structure, sewing structure, etc.), the connection strength at the nodes of the geocell is significantly improved. This structure makes the geocell more stable when bearing external forces, not easily breaking or falling off, thus enhancing the overall stability of the geocell.

[0019] Simple and efficient construction: Compared with the traditional welding or sewing connection methods, the overlapping connection method of the present invention is more simple and easy to implement, and construction can be completed without complex equipment and professional skills. This not only reduces the construction difficulty and cost, but also greatly improves the construction efficiency and shortens the project cycle.

[0020] Strong adaptability: The node structure design of the geocell of the present invention is flexible and can meet the requirements of different engineering environments. The setting of the limiting device (such as round rod, rhombic rod, sheet, ring, U-shaped bolt, etc.) further restricts the movement of the cell sheet and improves the stability of the node. At the same time, the hole or notch design at the folded end facilitates the passing of the connecting device, increasing the flexibility of the connection.

[0021] Prolonged service life: Due to the high node connection strength, simple construction and good stability, the geocell of the present invention can better maintain its original shape and structure during use, reducing the risk of overall structural failure caused by damage at the connection, thus prolonging the service life of the geocell.

[0022] Improve engineering quality: Applying the overlapping geocell of the present utility model to projects such as roads, railways, water conservancy, and environmental protection can effectively improve the construction quality of projects such as foundation reinforcement, slope protection, and soil stabilization. The improvement in the stability and construction efficiency of the geocell directly promotes the improvement of the overall project quality.

[0023] In summary, the overlapping geocell provided by the present utility model shows significant advantages in terms of connection strength, construction efficiency, adaptability, service life, and engineering quality, and has high application value and promotion prospects.

[0036] See also Figures 1 to 2 The embodiment of the present application provides an overlapping geocell, including a first cell sheet 1, a second cell sheet 2, and a connecting device 3 arranged at the overlapping portion of the first cell sheet 1 and the second cell sheet 2; the first cell sheet 1 and the second cell sheet 2 are respectively folded back to form a folded end portion 11, and the folded end portions 11 of the first cell sheet 1 and the second cell sheet 2 overlap with each other; the connecting device 3 connects the first cell sheet 1 and the second cell sheet 2 to form a cell node.

[0037] Optionally, the first cell sheet 1 / the second cell sheet 2 can be folded back multiple times to form multiple folded ends 11, and the folded ends 11 of the first cell sheet 1 and the second cell sheet 2 are stacked alternately, and then the first cell sheet 1 and the second cell sheet 2 are connected using the connecting device 3.

[0038] In one embodiment, a limiting member 4 is provided in the folded end portion 11. The limiting member 4 can open the folded end portion 11 so that the folded end portion 11 is clamped and fixed on the connecting device 3, thereby preventing the cell sheet from being loosened from the connecting device 3 when subjected to force, and improving the node connection strength of the overlapping geocells.

[0039] The main function of the limiting member 4 is to prevent the lattice cell sheets from loosening from the connecting device 3, acting like a bolt. Specifically, the shape of the limiting member 4 can be rod-shaped, sheet-shaped, ring-shaped, U-shaped or other structures.

[0040] As Figure 5 shown, in addition, the limiting member 4 is connected to the connecting device 3, making it not easy for the limiting member 4 to slip off, and at the same time, it is convenient to install. Specifically, the limiting member 4 is connected to the connecting device 3 by welding or other means, or the limiting member 4 and the connecting device 3 are set into an integral structure, etc.

[0041] As Figures 3 - 4 shown, in one embodiment, the folded end 11 is provided with a hole 12 or a notch 13 for facilitating the installation of the connecting device 3. In addition, the specific shape and the number of openings of the hole 12 and the notch 13 can be designed according to actual requirements.

[0042] The design of the hole 12 or the notch 13 enables the connecting device 3 (such as clip bolts, U-shaped nails, etc.) to easily pass through the folded end 11 of the lattice cell sheet, realizing precise alignment and rapid installation. This not only simplifies the installation process, but also improves the installation efficiency and reduces the construction difficulty. In addition, through the guidance of the hole 12 or the notch 13, the connecting device 3 can act more accurately between the overlapping lattice cell sheets, ensuring a tight combination between the connecting device 3 and the lattice cell sheet. This tight combination helps to improve the strength and stability of the node connection, making the geogrid more stable when bearing external forces.

[0043] In one embodiment, the connecting device 3 can be any one of a clip bolt structure, a clip riveting structure, a U-shaped nail weaving structure, and a sewing structure.

[0044] As Figures 1 - 2 shown, specifically, the clip bolt structure includes a pair of clips 31 (the clip 31 can specifically be a steel clip 31 or a clip 31 made of other materials), and a threaded member 32 (specifically can be a bolt). Among them, the clips 31 are respectively located on both sides of the overlapping part of the first lattice cell sheet 1 and the second lattice cell sheet 2; the threaded member 32 is arranged on the clip 31, and the threaded member 32 locks the clip 31 so that the clip 31 clamps and fixes the overlapping part of the first lattice cell sheet 1 and the second lattice cell sheet 2. By tightening the threaded member 32, the clips 31 on both sides clamp the first lattice cell sheet 1 and the second lattice cell sheet 2 in the middle (clamping the overlapping part of the first lattice cell sheet 1 and the second lattice cell sheet 2), so as to realize the connection and fixation of the first lattice cell sheet 1 and the second lattice cell sheet 2, forming a node.

[0045] When the connecting device 3 adopts a clip riveting structure, the threaded member 32 in the clip bolt structure can be replaced with a rivet, and by using the method of riveting and fixing to lock the clips 31 on both sides, the clips 31 clamp and fix the first lattice cell sheet 1 and the second lattice cell sheet 2.

[0046] The edge of the collet 31 is set to be arc-shaped to reduce the damage of the collet 31 to the first compartment piece 1 and the second compartment piece 2.

[0047] In addition, the U-shaped nail weaving structure (weaving U-shaped nails at the overlapping position of the first compartment piece 1 and the second compartment piece 2) and the sewing structure (sewing and connecting the overlapping position of the first compartment piece 1 and the second compartment piece 2) can both be used as the connecting device 3 for connecting and fixing the first compartment piece 1 and the second compartment piece 2 to form a node.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
