Abstract
Description
Technical Field
[0001] This utility model relates to the field of geotechnical construction technology, specifically to a geocell. Background Technology
[0002] Geocells are sheet-like cell structures. They are flexible and can be folded up for transportation, saving transport space. When in use, they can be unfolded and filled with soil, rock, or concrete to form a structure with strong lateral confinement and high rigidity. Geocells are mainly used as a subbase to treat weak foundations and increase their bearing capacity. They can also be laid on slopes to form slope protection structures and can be used to construct retaining structures. However, traditional geocells currently have the following disadvantages:
[0003] First, in general, sandwich-type geocells, such as those using riveting or bolting, the geocell sheets are laid flat in the middle of the sandwich, resulting in insufficient constraint on the geocell sheets, uneven stress at the joints, and particularly low peel strength at the joints.
[0004] Secondly, the sharp edges and corners of the clamping body increase the processing difficulty, making it impossible to guarantee the yield rate, which in turn leads to increased costs. Utility Model Content

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

A third through hole is opened between any two adjacent first protrusions.
[0009] The second clamping body includes a second clamping plate. A plurality of third protrusions are arranged longitudinally side by side on the left side of the second clamping plate. A fourth through hole is provided on each of the plurality of third protrusions. A fifth through hole is provided between any two adjacent third protrusions. The number of first protrusions is at least one more than the number of third protrusions.
[0010] The first protrusion is fitted through the fifth through hole, and the third protrusion is fitted through the third through hole;
[0011] Geocell sheet, the geocell sheet includes a first narrow strip group and a second narrow strip group, the geocell sheet is located between the first clamping body and the second clamping body, and the first narrow strip group is pushed outward from the first protrusion located in the middle and wrapped around the first protrusion, and the second narrow strip group is pushed outward from the third protrusion and wrapped around the third protrusion.
[0012] The insert includes a first insert and a second insert, wherein the first insert is inserted into a plurality of first through holes, and the second insert is inserted into a plurality of fourth through holes and two second through holes.
[0013] In one embodiment, the front and rear ends of the first and second clamping plates, the right end of the first protrusion, and the left ends of the second and third protrusions are respectively arc-shaped.

[0015] The upper surface of the third protrusion at the top is flush with the upper surface of the second clamping plate, and the lower surface of the third protrusion at the bottom is flush with the lower surface of the second clamping plate.
[0016] In one embodiment, the second clamp is located between the two second protrusions.
[0017] In one embodiment, the first through hole and the two second through holes at the top are circular, and the plurality of first through holes and the plurality of fourth through holes located below the top are waist-shaped holes.
[0018] In one embodiment, several of the third and fifth through holes are rectangular, and each of their corners is rounded.
[0019] In one embodiment, a first groove is longitudinally provided between any two of the third through holes, and the first groove is located on the left side wall of the first clamping plate, and a plurality of the first grooves are located on the same straight line.

[0043] A geocell, comprising:
[0044] The first clamping body 1 includes a first clamping plate 2. Five first protrusions 3 are arranged longitudinally side by side on the right side of the first clamping plate 2, and a second protrusion 4 is arranged at the upper and lower ends of the left side. A first through hole 5 is arranged on each of the five first protrusions 3, and a second through hole 6 is arranged on each of the two second protrusions 4. A third through hole 7 is opened between any two adjacent first protrusions 3.
[0045] The second clamping body 8 includes a second clamping plate 9. Four third protrusions 10 are arranged longitudinally side by side on the left side of the second clamping plate 9. Each of the four third protrusions 10 is provided with a fourth through hole 11. A fifth through hole 12 is provided between any two adjacent third protrusions 10.
[0046] The first protrusion 3 is fitted into the fifth through hole 12, and the third protrusion 10 is fitted into the third through hole 7.
[0047] Geocell sheet 13 includes a first narrow strip group 14 and a second narrow strip group 15. Specifically, multiple transverse slits are made on the geocell sheet 13 to form the first narrow strip group 14 and the second narrow strip group 15. The geocell sheet 13 is located between the first clamping body 1 and the second clamping body 2. The first narrow strip group 14 is pushed outward from the first protrusion 3 located in the middle position and wrapped around the first protrusion 3. The second narrow strip group 15 is pushed outward from the third protrusion 10 and wrapped around the third protrusion 10.
[0048] Insert rod 16 includes a first insert rod 17 and a second insert rod 18. The first insert rod 17 is inserted into five first through holes 5, and the second insert rod 18 is inserted into four fourth through holes 11 and two second through holes 6.
[0049] The geocell provided by this utility model involves setting a first narrow strip group 14 and a second narrow strip group 15 on the geocell sheet 13, then combining the first clamping body 1 and the second clamping body 8, and using the first protrusion 3 to push the first narrow strip group 14 outward along the fifth through hole 12, so that the first narrow strip group 14 fits on the outer side of the first protrusion 3; similarly, using the third protrusion 10 to push the second narrow strip group 15 outward along the third through hole 7, so that the second narrow strip group 15 fits on the outer side of the third protrusion 10. On the side, the first clamping plate 2 and the second clamping plate 9 are locked by the cooperation between the first protrusion 3 and the fifth through hole 12 and between the third protrusion 10 and the third through hole 7, so that the first narrow strip group 14 and the second narrow strip group 15 of the geocell sheet 13 are pushed out and opened to both sides under the action of the first protrusion 3 and the third protrusion 10, thereby increasing the constraint force on the geocell sheet 13, and the insertion of the first insert rod 17 and the second insert rod 18 is used to prevent the first clamping body 1 and the second clamping body 8 from loosening.
[0050] When the geocell sheet 13 is under stress, the stress can be transferred to the clamping body through the protrusions. Since the geocell sheet 13 at the joint is basically undamaged, it can maintain a high tensile strength.
[0051] In this embodiment, the front and rear ends of the first clamping plate 2 and the second clamping plate 9, the right end of the first protrusion 3, and the left ends of the second protrusion 4 and the third protrusion 10 are respectively arc-shaped. This design makes the overall weight of the first clamping body 1 and the second clamping body 8 lighter, and the rounded shape is conducive to the injection molding process.
[0052] In this embodiment, the upper surfaces of the first protrusion 3 and the second protrusion 4 located at the top are flush with the upper surface of the first clamping plate 2, and the lower surfaces of the first protrusion 3 and the second protrusion 4 located at the bottom are flush with the lower surface of the first clamping plate 2.
[0053] The upper end face of the third protrusion 10 at the top is flush with the upper end face of the second clamping plate 9, and the lower end face of the third protrusion 10 at the bottom is flush with the lower end face of the second clamping plate 9.
[0054] Furthermore, the second clamping plate 9 is located between the two second protrusions 4, so that the first clamping body 1 and the second clamping body 8 cooperate with each other to clamp and fix the geocell sheet 13. In this way, the force from the geocell sheet 13 can be transmitted more evenly to the first clamping body 1 and the second clamping body 8, making the force on each part of the entire geocell more even, thereby extending the service life of the geocell.
[0055] In this embodiment, the first through hole 5 and the two second through holes 6 located at the top are respectively circular, which facilitates a tight fit between the first through hole 5 and the two second through holes 6 and the second insertion rod 18, thereby locking the first clamping plate 2 and the second clamping plate 9.
[0056] The five first through holes 5 and the four fourth through holes 11 located below the top are waist-shaped holes. This is to facilitate the slight local deformation that may occur after the geocell sheet 13 is placed between the first clamping body 1 and the second clamping body 8. By setting the waist-shaped holes, the slight deformation of the first clamping body 1 and the second clamping body 8 can be moderately offset to ensure that the first insertion rod 17 and the second insertion rod 18 can be inserted smoothly.
[0057] In this embodiment, the four third through holes 7 and the three fifth through holes 12 are rectangular, and each of their corners is rounded, which facilitates the first protrusion to pass through and fit into the fifth through hole 12, and the third protrusion 10 to pass through and fit into the third through hole 7.
[0058] In this embodiment, a first groove 19 is longitudinally provided between any two third through holes 7, and the first groove 19 is located on the left side wall of the first clamping plate 2, and the three first grooves 19 are located on the same straight line.
[0059] Each of the fifth through holes 12 has a second groove 20 longitudinally arranged at its upper and lower ends, and the second groove 20 is located on the right side wall of the second clamping plate 9. The four second grooves 20 are located on the same straight line. The first insertion rod 17 is inserted into the four second grooves 20, and the second insertion rod 18 is inserted into the three first grooves 19. By setting the first grooves 19 and the second grooves 20 on the first clamping plate 2 and the second clamping plate 9, not only is the weight of the first clamping plate 2 and the second clamping plate 9 reduced, but the middle part of the first insertion rod 17 and the second insertion rod 18 is also guided and limited.
[0060] In this embodiment, a connecting plate 21 is provided between the upper ends of the first insertion rod 17 and the second insertion rod 18, so that the first insertion rod 17, the second insertion rod 18 and the connecting plate 21 form a whole, thereby improving the installation efficiency of the insertion rod 16; the cross-sections of the first insertion rod 17 and the second insertion rod 18 are circular, and the cross-sections of the first groove 19 and the second groove 20 are arc-shaped, so that the first insertion rod 17 and the second insertion rod 18 can be well fitted and installed with the first groove 19 and the second groove 20, thereby improving the connection strength between the insertion rod 16 and the first clamping plate 2 and the second clamping plate 9.
[0061] In this embodiment, the outer surfaces of the first clamping plate 2, the first protrusion 3, the second protrusion 4, the second clamping plate 9, and the third protrusion 10 are respectively roughened to increase the friction between these components and the geocell sheet 13 and the soil.
[0062] It should be noted that:
[0063] There are many methods for roughening the surface of an object. Here are some common methods:
[0064] Machining
[0065] Grinding: Using equipment such as grinding machines and abrasive grinding wheels, material is removed by friction between the grinding wheel or abrasive and the surface of an object, increasing the surface roughness. This method allows for precise control of the magnitude and uniformity of roughness and is suitable for various metallic and non-metallic materials.
[0066] Sandblasting: This process uses compressed air to propel sand grains or other abrasive materials at high speed onto the surface of an object, impacting and scratching it to roughen the surface. Sandblasting can produce varying degrees of roughness and can handle objects with complex shapes, but it is necessary to carefully control the particle size, blasting pressure, and time to avoid excessive roughness or surface damage.
[0067] Shot blasting: Similar to sandblasting, but using shot (such as steel shot, glass shot, etc.) instead of abrasive particles. Shot blasting not only roughens the surface but also improves its hardness and fatigue strength, and is commonly used for surface treatment of metal products.
[0068] Chemical treatment
[0069] Pickling: Immersing an object in an acid solution, the chemical reaction dissolves some of the surface material, thus roughening the surface. Pickling is suitable for metallic materials; different acids and processing times can produce different roughening effects, but rigorous cleaning and rust prevention treatment are necessary after pickling.
[0070] Chemical etching: This method uses specific chemical solutions to etch the surface of an object, creating a rough texture. It can be used in situations where precise roughness is not required, but a uniformly rough surface is desirable, such as the surface treatment of materials like plastics and ceramics.
[0071] Physical treatment method
[0072] Laser processing: This method uses a high-energy-density laser beam to irradiate the surface of an object, causing the surface material to melt or vaporize instantaneously, forming tiny pits or bumps, thus achieving roughening. Laser processing can precisely control the location and degree of roughness and is suitable for various materials, especially in fields such as microelectronics and optics.
[0073] Plasma treatment: In a plasma environment, the surface of an object is bombarded by particles such as ions, electrons, and free radicals, altering its surface structure and making it rougher. Plasma treatment can be performed at relatively low temperatures, causing less damage to the material, and is often used for surface modification of polymer materials such as plastics and rubber.
[0074] Coating method
[0075] Roughened Coating by Spraying: This method involves spraying a coating containing particulate fillers, such as anti-slip paint or textured paint, to form a rough-textured coating on the surface of an object. This method is simple and easy to implement, and the roughness can be controlled by selecting fillers of different particle sizes as needed. It is suitable for surface protection and decoration of various objects.
[0076] Thermal spraying involves heating metal or ceramic powder to a molten or semi-molten state, then spraying it at high speed onto the surface of an object through a spray gun to form a rough coating. Thermal spray coatings have high bonding strength and wear resistance, and are often used for the repair and surface strengthening of mechanical parts.
[0077] Therefore, the roughening process mentioned in this embodiment can be reasonably selected from the methods described above.
[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0079] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
