Description

Technical Field

[0001] This utility model relates to the field of geocell technology, and in particular to a connection structure and a geocell. Background Technology

[0002] Geocells are widely used in various engineering applications, such as roads, railways, and dams, and can effectively enhance the bearing capacity, stability, and erosion resistance of soil.

[0003] In geocells, the reinforcing strips interact with the soil, increasing the friction between the soil and the geocell, thereby enhancing the geocell's restraint effect on the soil. The connecting structure is used to connect the reinforcing strips, ensuring that the strips form a stable and effective whole.

[0004] Currently, when using existing geocells on construction sites, the design of the connection structure makes assembly and disassembly operations quite complex. Construction workers need to spend a lot of time and effort installing and disassembling the connection structure, resulting in low construction efficiency. Furthermore, the stability of the existing connection structure is poor. During construction and use, when subjected to external forces such as soil pressure and vibration, the connection structure is prone to displacement, making it difficult to ensure reliable connections between the reinforcing strips, thus affecting the overall stability of the geocell structure. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure and geocell to solve the technical problems of poor stability and difficulty in disassembly and assembly of the connection structure of geocell in the prior art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] On the one hand, this utility model provides a connection structure, including:

[0008] The central body has multiple limiting slots extending from the edge to the center, and the multiple limiting slots converge in the central area of ​​the central body for inserting reinforcing strips respectively.

[0009] The lower support and the top cover are detachably fastened to the lower and upper ends of the middle body. The lower support and the top cover are respectively provided with positioning grooves corresponding to the limiting through grooves on the side facing the middle body. The positioning grooves and the limiting through grooves together form a fixing channel for accommodating and fixing the rib.

[0010] The insert body is insertably disposed in the central body. The insert body has a fixing groove, which can simultaneously engage with multiple reinforcing strips at the intersection of multiple limiting through grooves to compress the reinforcing strips.

[0011] Preferably, the central body includes two connecting bodies that can be spliced ​​together to form the central body. The connecting bodies are provided with limiting slots, and the limiting slots on the two connecting bodies correspond one-to-one, with the two corresponding limiting slots located in the same plane.

[0012] Preferably, the edges of the lower support and the top cover extend toward the central body to form limiting edges, which are used to restrict the separation of the two connecting bodies.

[0013] Preferably, the positioning groove is provided on the limiting edge.

[0014] Preferably, the central body has a connecting groove, and the plug-in body can be inserted into the connecting groove. The connecting groove and a plurality of limiting through grooves intersect in the central area of ​​the central body.

[0015] Preferably, the height of the limiting groove is greater than or equal to the height of the reinforcing strip, and the width of the limiting groove is greater than or equal to the width of the reinforcing strip.

[0016] Preferably, the radial cross-section of the central body is one of a circle, a rectangle, or a triangle.

[0017] On the other hand, this utility model also provides a geocell, including multiple reinforcing strips and multiple connecting structures as described above. The multiple reinforcing strips are arranged together to form a receiving space for receiving filling material. At least a portion of each reinforcing strip is inserted into the limiting groove of the connecting structure.

[0018] Preferably, the reinforcing strip is an integral planar structure without any holes on its surface; or, the reinforcing strip has multiple mesh holes distributed in a dot matrix pattern.

[0019] Preferably, the shape of the mesh is at least one of circular, rhomboid, triangular or rectangular.

[0020] The beneficial effects of this utility model are:

[0021] The connection structure proposed in this utility model effectively solves the problems of inconvenient assembly and disassembly and poor stability in existing connection structures through the coordinated operation of the central main body, lower support, top cover, and plug-in body. During installation, the reinforcing strips are simply inserted from the edge of the central main body into the limiting groove until they intersect. Then, the plug-in body is inserted into the intersection, and the fixing groove on the plug-in body simultaneously clamps multiple reinforcing strips. The lower support and top cover are then fastened together, so that the positioning groove and the limiting groove together form a fixed channel for wrapping the reinforcing strips, firmly constraining them within the fixed channel. The plug-in body applies additional radial clamping force at key nodes, enhancing the connection point's resistance to external forces such as soil pressure and vibration, preventing relative sliding of the reinforcing strips and displacement of the connection structure, thereby ensuring the overall stability of the geocell structure. Simultaneously, the entire connection process requires no complex tools or cumbersome operations, only simple insertion and fastening, reducing the labor intensity and time costs for construction workers and improving construction efficiency. Furthermore, the detachable design facilitates later maintenance or adjustment, making it highly practical. Attached Figure Description

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] See Figures 1 to 4 The connection structure provided in this embodiment of the utility model includes a central body 1, a lower support 2, a top cover 3, and an insert body 4. The central body 1 has multiple limiting grooves 11 extending from the edge to the center, which converge in the central area of ​​the central body 1 for inserting reinforcing strips 100. The lower support 2 and the top cover 3 are detachably fastened to the lower and upper ends of the central body 1, respectively. The lower support 2 and the top cover 3, facing the central body 1, each have a positioning groove 5 corresponding to the limiting grooves 11. The positioning grooves 5 and the limiting grooves 11 together form a fixing channel 6 for accommodating and fixing the reinforcing strips 100. The insert body 4 is insertably disposed in the central body 1 and has a fixing groove 41. The fixing groove 41 can simultaneously engage with multiple reinforcing strips 100 at the intersection of the multiple limiting grooves 11 to compress the reinforcing strips 100.

[0036] The connection structure proposed in this utility model effectively solves the problems of inconvenient assembly and disassembly and poor stability of existing connection structures through the coordinated cooperation of the central main body 1, the lower support body 2, the top cover body 3, and the plug-in body 4. During installation, the reinforcing strips 100 are simply inserted into the limiting groove 11 from the edge of the central main body 1 until they intersect. Then, the plug-in body 4 is inserted into the intersection, and the fixing groove 41 on the plug-in body 4 simultaneously clamps multiple reinforcing strips 100. The lower support body 2 and the top cover body 3 are then fastened together, so that the positioning groove 5 and the limiting groove 11 together form a fixing channel 6 that wraps around the reinforcing strips 100. This ensures that the reinforcing strips 100 are firmly constrained within the fixing channel 6. Furthermore, the plug-in body 4 applies additional radial clamping force at key nodes, enhancing the connection point's resistance to external forces such as soil pressure and vibration, preventing relative sliding of the reinforcing strips 100 and displacement of the connection structure, thereby ensuring the overall stability of the geocell structure. Meanwhile, the entire connection process requires no complex tools or cumbersome operations; it can be completed simply by plugging and snapping, reducing the labor intensity and time costs for construction workers and improving construction efficiency. Furthermore, the detachable design facilitates later maintenance or adjustments, making it highly practical.

[0037] Generally speaking, when the connecting structure is placed, the height direction of the connecting structure is the vertical direction. The lower support 2, the middle main body 1, the plug body 4 and the top cover 3 are arranged vertically from top to bottom. The limiting through groove 11, the positioning groove 5 and the fixing groove 41 all extend vertically. For the convenience of describing with reference to the attached drawings, the directions in the following text are described with reference to the directions shown in the attached drawings, but are not limited by them.

[0038] The specific structure and working principle of this connection structure will be described in detail below.

[0039] The central main body 1 includes two connecting bodies 12, which can be spliced ​​together to form the central main body 1. Each connecting body 12 has a limiting groove 11, and the limiting grooves 11 on the two connecting bodies 12 correspond one-to-one, with the two corresponding limiting grooves 11 located in the same plane. This design allows construction workers to first place multiple reinforcing strips 100 into the limiting groove 11 of one of the connecting bodies 12, and then align and join the other connecting body 12, thus easily completing the initial positioning and installation of the reinforcing strips 100 within the central main body 1. This effectively avoids the operational difficulties of simultaneously inserting multiple reinforcing strips 100 into narrow spaces, as is required in integral structures, simplifying the installation process. Meanwhile, the corresponding limiting grooves 11 on the two connecting bodies 12, which are located in the same plane, ensure that the fixed channel 6 formed after mating has precise concentricity and flatness, so that the reinforcing strip 100 can be clamped evenly and straight, avoiding bending of the reinforcing strip 100 or local stress concentration caused by channel misalignment, thereby enhancing the integrity and uniformity of the connection node.

[0040] In other embodiments, the central body 1 can be an integral structure formed in one piece, or it can be formed by splicing together three, four or more connecting bodies 12. It is worth noting that as long as the final central body 1 can form a limiting through groove 11 for stably accommodating and fixing the reinforcing strip 100, the specific structure of the central body 1 and the number of connecting bodies 12 are not limited here.

[0041] Furthermore, the edges of the lower support 2 and the top cover 3 extend towards the middle body 1 to form limiting edges 7, which are used to restrict the separation of the two connecting bodies 12. Thus, when the lower support 2 is engaged with the top cover 3, radial restraint is formed from both the upper and lower sides of the two mating connecting bodies 12, effectively preventing lateral misalignment or separation tendency of the connecting bodies 12 under external loads or vibrations, enhancing the overall structural rigidity and connection reliability of the middle body 1 composed of the split connecting bodies 12. Simultaneously, the limiting edges 7 naturally serve as positioning guides during installation, enabling the lower support 2, middle body 1, and top cover 3 to be quickly and accurately aligned and engaged, simplifying the assembly operation.

[0042] Specifically, a positioning groove 5 is provided on the limiting edge 7, so that when the lower support 2 and the top cover 3 are fastened to the middle body 1, the limiting edge 7 not only surrounds and restricts the position of the two connecting bodies 12 from the side, but also the positioning groove 5 on the edge itself can be more accurately aligned with the limiting through groove 11 on the connecting body 12 in the side direction and together form a complete side wall of the fixed channel 6. This achieves a more comprehensive and tighter wrapping and locking of the reinforcing strip 100 from the radial to the lateral direction, effectively preventing the reinforcing strip 100 from sliding or lifting laterally in the fixed channel 6, further improving the ability of the connection point to resist external forces in all directions, and enhancing the stability of the connection.

[0043] A connecting groove 13 is provided on the central body 1, into which the insert body 4 can be inserted. The connecting groove 13 and multiple limiting through grooves 11 intersect in the central area of ​​the central body 1. The connecting groove 13 precisely guides and limits the installation position and insertion path of the insert body 4. The design of the connecting groove 13 intersecting with each limiting through groove 11 in the central area ensures that when the insert body 4 is inserted along the connecting groove 13, the fixing groove 41 can accurately and synchronously reach the convergence point of multiple reinforcing strips 100 and engage with all reinforcing strips 100, thereby achieving concentrated compression of the core area where the reinforcing strips 100 intersect. This effectively prevents the risk of uneven compression force or individual reinforcing strips 100 falling off due to the positional deviation of the insert body 4.

[0044] Understandably, the height of the limiting groove 11 is greater than or equal to the height of the reinforcing strip 100, and the width of the limiting groove 11 is greater than or equal to the width of the reinforcing strip 100. This ensures that the reinforcing strip 100 can be smoothly and unobstructedly inserted into the groove until it reaches the central intersection area. This avoids the reinforcing strip 100 from being squeezed, deformed, or worn due to the limiting groove 11 being too small, and also prevents the reinforcing strip 100 from excessively shaking within the limiting groove 11 if the limiting groove 11 is too large. Thus, the integrity of the reinforcing strip 100 is protected while achieving effective fixation.

[0045] The radial cross-section of the central main body 1 can be circular, rectangular, or triangular. A circular cross-section is non-directional, facilitating quick alignment during installation and resulting in more even stress distribution. A rectangular cross-section allows for better integration with other components having flat surfaces, promoting a compact layout. A triangular cross-section may offer higher structural stability and torsional resistance. In practical applications, the specific cross-sectional shape of the connecting structure can be adaptively adjusted according to the specific cell layout, space constraints, or special mechanical requirements, which will not be elaborated upon here.

[0046] In other embodiments, the radial cross-section of the central body 1 may also be polygonal, elliptical or other irregular shapes. Its specific shape is not a limitation of this utility model. Any cross-sectional shape that can realize the arrangement of the limiting through groove 11 and the insertion function of the plug-in body 4 falls within the protection scope of this utility model.

[0047] It is understandable that the lower support 2 and the top cover 3 are designed to fit the radial cross-section of the middle body 1 so that they can be tightly fastened to both ends of the middle body 1, thereby achieving a good fit, ensuring the continuity of the fixed channel 6 formed by the limiting through groove 11 and the positioning groove 5, and facilitating the application of uniform constraint force to ensure the overall stability and sealing effect of the connection.

[0048] Example 2

[0049] See Figure 5This utility model embodiment also provides a geocell, which includes multiple reinforcing strips 100 and multiple connecting structures provided in Embodiment 1. The multiple reinforcing strips 100 together form a receiving space 200 for receiving filling material. At least a portion of each reinforcing strip 100 is inserted into the limiting groove 11 of the connecting structure, so that each connecting node of the geocell has the characteristics of easy disassembly and assembly and high stability. The entire geocell laying construction process becomes efficient and fast, and construction personnel can quickly complete the construction of large-area geocell grids, improving project efficiency. At the same time, the connecting structures distributed throughout each node of the grid can reliably fasten the reinforcing strips 100 together, ensuring that the geocell grid can maintain a uniform and stable shape when filled with soil and bearing loads, effectively preventing grid deformation or overall structural instability caused by local connection failure, thereby enhancing the geocell's constraint capacity on the filling material and its overall bearing capacity, and extending the service life of the engineering structure.

[0050] The filling materials are generally gravel, soil or concrete, which are easy to obtain, low in cost, and have high permeability and erosion resistance.

[0051] Optionally, the reinforcing strip 100 is an integral planar structure without any holes on its surface; or, the reinforcing strip 100 has multiple mesh holes distributed in a dot matrix pattern.

[0052] When the reinforcing strip 100 adopts an integral planar structure without pores, it has higher material strength and structural stiffness, and can provide more robust lateral restraint, making it particularly suitable for heavy-duty engineering environments with high requirements for tensile strength and wear resistance.

[0053] When multiple mesh openings are formed in a dot-matrix pattern on the reinforcing strip 100, the mesh openings can form an effective mechanical interlock between the filling material and the reinforcing strip 100, increasing the interlocking friction between the reinforcing strip 100 and the soil or gravel filling material, enhancing the integrity between the cell grid and the filling material, and preventing filler loss. The specific implementation of the reinforcing strip 100 can be selected according to the actual working conditions and is not limited here.

[0054] Preferably, the shape of the mesh is at least one of circular, rhomboid, triangular or rectangular.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
