Abstract
Description
Technical Field
[0001] This utility model relates to the field of geocell technology, specifically to a mortise and tenon structure for a folded geocell and a geocell. Background Technology
[0002] As an important geosynthetic material, geocells play a significant and diverse role in the field of civil engineering, and are widely used in many engineering scenarios such as roadbed reinforcement, slope protection, and soft soil treatment.
[0003] Currently, the common method for constructing geocells involves connecting two strip sheets using a multi-point fixing process, followed by stretching to form several three-dimensional cell structures with specific spatial shapes. Among existing fixing techniques, welding is a commonly used method. However, over long-term use, weld cracking is prone to occur at the welded joints, leading to separation of the two sheets. To overcome the shortcomings of welding, some engineering practices employ drilling holes in the sheets and then securing them with bolts and nuts.
[0004] From the perspective of materials mechanics, drilling holes in sheet materials damages the sheet's intrinsic structure. After drilling, the stress distribution around the hole changes, creating stress concentration. This makes the sheet more prone to cracking at the hole when subjected to external forces, resulting in a significant reduction in the overall strength of the sheet. Furthermore, the added drilling process not only complicates the manufacturing process and reduces production efficiency but also increases costs. Utility Model Content
[0005] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a mortise and tenon structure for folded geocells.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] A mortise and tenon structure for a folded geocell includes a socket and a plug rod. The socket includes a base plate with two limiting tubes and two guide holes. Multiple strips are bent on the socket and then inserted into the socket for limiting.
[0008] Furthermore, the bottom of the limiting tube and guide hole is formed with a plug slot, the plug rod includes a cross plate, the bottom of the cross plate is provided with four connecting rods, and the end of the connecting rod is provided with a snap connector.
[0009] Furthermore, the connector can be snapped into the insertion slot.
[0010] Furthermore, the card connector can pass through the limiting tube and be inserted into the card slot hole.
[0011] Furthermore, the snap-fit connector includes two inverted conical inserts, and two separators are formed at the bottom of the connecting rod, with a gap between the two separators, and the inverted conical inserts are mounted on the separators.
[0012] Furthermore, a central gap is formed between the two limiting tubes to accommodate the strip passing through.
[0013] Furthermore, the insertion rod includes a cross plate, and the bottom of the cross plate is provided with two thick insertion rods and two thin insertion rods, with the thick insertion rods and thin insertion rods spaced apart.
[0014] Furthermore, the thicker insert engages with the guide hole, and the thinner insert engages with the limiting tube.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: The cooperation between the through-clamp connector and the insertion slot hole of this utility model achieves a firm connection between the insertion rod and the socket, improving the peeling force and restraint force of the geocell. No drilling or welding is required on the sheet material, avoiding damage to the sheet material's structure and maintaining its original strength.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0027] like Figures 1-4 As shown, a mortise and tenon structure for a folded geocell includes a socket 2 and a plug rod 1. The socket includes a base plate 21, two limiting tubes 22 and two guide holes 23 on the base plate. The socket has multiple strips bent on it and then connected to the plug rod for positioning.
[0028] Furthermore, the bottom of the limiting tube and guide hole is formed with a plug slot 24, the plug rod includes a cross plate 11, the bottom of the cross plate is provided with four connecting rods 12, and the end of the connecting rod is provided with a snap connector 13.
[0029] The solution is further refined so that the connector can be snapped into the slot of the connector.
[0030] Furthermore, the card connector can pass through the limiting tube and be inserted into the card slot hole.
[0031] Furthermore, such as Figure 2 As shown, the snap-fit connector includes two inverted conical inserts 132, and two separators 131 are formed at the bottom of the connecting rod, with a gap between the two separators. The inverted conical inserts are mounted on the separators. Because the separators have a certain degree of elasticity, when the inverted conical inserts move along the limiting tube and guide hole, the two inverted conical inserts are forced together and move closer to each other. When the inverted conical inserts reach the insertion slot, they are no longer forced, allowing the two inverted conical inserts to engage with the insertion slot.
[0032] The existing geocell includes strips 100. When this mortise and tenon structure is used, the two adjacent overlapping strips are bent into a shape similar to "8" at the node, and then directly connected and fixed with sockets and plugs. The structure is strong and easy to operate. There is no need to drill holes or weld on the sheet, which maintains the original strength of the sheet and simplifies the operation process. Moreover, it greatly improves the peel force and restraint of the geocell.
[0033] A central gap is formed between the two limiting tubes to accommodate the strip passing through. Because the strip experiences greater stress at the central gap after bending, limiting tubes must be installed to enhance the fixing effect, rather than directly inserting the rod into the base plate, which would easily cause the rod to deform under stress.
[0034] In some embodiments, such as Figure 5 and Figure 6 As shown, the socket includes a base plate 21, on which two limiting tubes 22 are provided, and two guide holes 23 are provided on the base plate, wherein the two guide holes are respectively located on both sides of the limiting tubes. The base plate can be a cross-shaped plate.
[0035] The insertion rod includes a cross plate 11, and the bottom of the cross plate is provided with two thick insertion rods 121 and two thin insertion rods 122, with the thick insertion rods and thin insertion rods spaced apart.
[0036] Furthermore, the thicker insert engages with the guide hole, and the thinner insert engages with the limiting tube.
[0037] When the socket and the plug are connected, the two thin plugs are inserted into the two limiting tubes at the same time, the thick plug is inserted into the guide hole.
[0038] Furthermore, an elastic rubber layer is formed on the surface of the thin insertion rod, and the elastic rubber layer undergoes elastic deformation when the thin insertion rod is inserted into the limiting tube.
[0039] A geocell employs the aforementioned mortise and tenon structure of a folded geocell.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
