Description

Technical Field

[0001] This utility model relates to the field of geogrid technology, and in particular to a connection structure for a honeycomb constraint system. Background Technology

[0002] Geocells can be used as a subbase to improve the bearing capacity of weak foundations, or laid on slopes to form slope protection structures. They can also be used to build retaining structures. Currently, they are widely used in shallow foundation treatment, slope erosion control, and urban large pipeline support projects. They are a foundation engineering construction material with great development potential.

[0003] Traditional geocell connection methods primarily employ welding and bolting. While these methods achieve connection, they present several challenges. First, welding is complex, requiring specialized equipment and technicians, and its quality is significantly affected by human factors, making it difficult to guarantee connection stability and reliability. Second, while bolting is relatively simple, it necessitates pre-drilling holes in the geocell, increasing manufacturing difficulty and cost. Furthermore, bolts are prone to loosening, affecting the long-term stability of the connection. Therefore, we propose a honeycomb constraint system connection structure to address these issues. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a connection structure for a honeycomb constraint system. It solves the problem that traditional geocell connection methods, such as welding and bolting, while achieving connection, have several drawbacks. First, welding is complex, requiring specialized welding equipment and technicians, and the welding quality is significantly affected by human factors, making it difficult to guarantee the stability and reliability of the connection. Second, while bolting is relatively simple, it requires pre-drilling holes in the geocell, increasing manufacturing difficulty and cost, and the bolts are prone to loosening, affecting the long-term stability of the connection.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A connection structure for a honeycomb constraint system includes a honeycomb grid, wherein connecting components are disposed between the honeycomb grids;

[0009] The connecting assembly includes a connecting plate disposed between the tops of two honeycomb grids, a flexible pad fixedly connected to the inner side of the connecting plate, a threaded hole on the other side of the connecting plate, and a guide groove provided on one side of the threaded hole.

[0010] Preferably, the threaded hole is internally threaded with a threaded rod, and one end of the threaded rod is rotatably mounted with a flexible pad via a bearing.

[0011] Preferably, a guide rod is fixedly connected to one side of the second flexible pad, and the guide rod is slidably embedded inside the guide groove.

[0012] Preferably, one end of the honeycomb grid is fixedly connected to a mounting plate, and the other end of the honeycomb grid is fixedly connected to a T-shaped plug. The mounting plate has a T-shaped slot inside that corresponds to the T-shaped plug.

[0013] Preferably, the honeycomb mesh is made of modified polymer composite material, which is composed of high-density polyethylene and copolymer polypropylene. It has good chemical resistance. Through cross-linking treatment, such as peroxide cross-linking or silane cross-linking, a three-dimensional network molecular structure is formed, which improves the creep resistance of the material and reduces stress fatigue cracking. Through molecular chain regularization treatment, the molecular chain slippage is more stable when the material is repeatedly stressed, reducing the generation of microcracks. Accelerated aging tests have verified that the service life of such modified materials can reach 3 to 5 times that of traditional materials under the same environment.

[0014] Preferably, the surface of the honeycomb grid has multiple elongated holes.

[0015] Preferably, the first flexible pad and the second flexible pad are made of rubber material, which has high elasticity and high static friction.

[0016] Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention achieves vertical connection of honeycomb grids by setting up T-shaped inserts, mounting plates, and T-shaped slots. The T-shaped inserts at one end of the honeycomb grid are inserted into the mounting plates at the other end of the honeycomb grid, and the T-shaped inserts can be fully inserted into the T-shaped slots.

[0019] This invention, by setting a connecting component, inserts a connecting plate between two honeycomb grids. When the threaded rod is rotated, the second flexible pad at one end of the threaded rod is tightly attached to the honeycomb grid under the constraint of the guide rod and guide groove, while the first flexible pad is tightly attached to the inner wall of the other honeycomb grid. Under the resistance force of the rotating threaded rod, the honeycomb grid can be effectively fixed. At the same time, the first and second flexible pads are made of rubber material, which has high static friction and can prevent slippage when fixing the honeycomb grid. Attached Figure Description

[0027] Example 1

[0028] The technical solution in this application aims to effectively address the shortcomings of traditional geocell connection methods, which often employ welding and bolting. While these methods achieve connection, they present several problems. First, welding is complex, requiring specialized welding equipment and technicians, and its quality is significantly affected by human factors, making it difficult to guarantee the stability and reliability of the connection. Second, while bolting is relatively simple, it requires pre-drilling holes in the geocell, increasing manufacturing difficulty and cost. Furthermore, bolts are prone to loosening, affecting the long-term stability of the connection. The overall approach is as follows:

[0029] like Figures 1 to 5To address the problems existing in the prior art, this utility model provides a connection structure for a honeycomb constraint system, including a honeycomb grid 11. A connection component 2 is provided between the honeycomb grids 11. The connection component 2 includes a connection plate 21 disposed between the tops of two honeycomb grids 11. A flexible pad 22 is fixedly connected to the inner side of the connection plate 21. A threaded hole 26 is provided on the other side of the connection plate 21. A guide groove 27 is provided on one side of the threaded hole 26. A threaded rod 23 is threadedly connected inside the threaded hole 26. One end of the threaded rod 23 is rotatably mounted via a bearing. The device is equipped with a second flexible pad 24, and a guide rod 25 is fixedly connected to one side of the second flexible pad 24. The guide rod 25 is slidably embedded in the inside of the guide groove 27. The surface of the honeycomb grid 11 has multiple elongated holes 12. The first flexible pad 22 and the second flexible pad 24 are made of rubber material, which has high elasticity and large static friction. One end of the honeycomb grid 11 is fixedly connected to a mounting plate 102, and the other end of the honeycomb grid 11 is fixedly connected to a T-shaped insert 101. The inside of the mounting plate 102 has a T-shaped slot 103 corresponding to the T-shaped insert 101.

[0030] By adopting the above technical solution, when connecting the honeycomb grid 11, firstly, the T-shaped insert 101 at one end of the honeycomb grid 11 is inserted into the mounting plate 102 at one end of the other honeycomb grid 11, so that the T-shaped insert 101 can be fully inserted into the T-shaped slot 103, thus realizing the vertical connection of the honeycomb grid 11. When connecting laterally, firstly, the connecting plate 21 is inserted between the two honeycomb grids 11, and the threaded rod 23 is rotated. At this time, the flexible pad 24 at one end of the threaded rod 23 is tightly attached to the honeycomb grid 11 under the restriction of the guide rod 25 and the guide groove 27, and the flexible pad 22 is tightly attached to the inner wall of the other honeycomb grid 11. Under the action of the resistance force of the rotation of the threaded rod 23, the honeycomb grid 11 can be effectively fixed. At the same time, the flexible pad 22 and the flexible pad 24 are made of rubber material, which has high static friction and can prevent slippage when fixing the honeycomb grid.

[0031] Example 2

[0032] like Figures 1 to 5 The honeycomb grid 11 is made of modified polymer composite material, which is composed of high-density polyethylene and copolymer polypropylene.

[0033] By adopting the above technical solutions, the material exhibits good chemical resistance. Through cross-linking treatment, such as peroxide cross-linking or silane cross-linking, a three-dimensional network molecular structure is formed, which improves the material's creep resistance and reduces stress fatigue cracking. Through molecular chain regularization treatment, the molecular chain slippage is more stable when the material is repeatedly subjected to stress, reducing the generation of microcracks. Accelerated aging tests have verified that the lifespan of this type of modified material can reach 3-5 times that of traditional materials under the same environment.

[0034] Working principle: In use, when connecting the honeycomb grids 11, firstly, insert the T-shaped plug 101 at one end of the honeycomb grid 11 into the mounting plate 102 at one end of the other honeycomb grid 11, ensuring that the T-shaped plug 101 is fully inserted into the T-shaped slot 103. This achieves a vertical connection of the honeycomb grids 11. When connecting laterally, first insert the connecting plate 21 between the two honeycomb grids 11, then rotate the threaded rod 23. At this time, the flexible pad 24 at one end of the threaded rod 23 is tightly attached to the honeycomb grid 11 under the constraint of the guide rod 25 and the guide groove 27, while the flexible pad 22 is tightly attached to the inner wall of the other honeycomb grid 11. Under the resistance force of the rotating threaded rod 23, the honeycomb grids 11 can be connected. 1. Effective fixation is achieved. Flexible pads 22 and 24 are made of rubber, which has high static friction, preventing slippage when fixing the honeycomb grid. The honeycomb grid 11 is made of modified polymer composite material, composed of high-density polyethylene and copolymer polypropylene, which has good chemical resistance. Through cross-linking treatment, such as peroxide cross-linking or silane cross-linking, a three-dimensional network molecular structure is formed, improving the material's creep resistance and reducing stress fatigue cracking. Through molecular chain regularization treatment, the molecular chain slippage is more stable under repeated stress, reducing microcrack generation. Accelerated aging tests have verified that the lifespan of this modified material under the same environment can reach 3-5 times that of traditional materials.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. 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. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
