Description

Technical Field

[0001] This utility model relates to the field of geogrids, specifically a multi-directional suspended geogrid. Background Technology

[0002] Geogrids are a major type of geosynthetic material. Compared with other geosynthetic materials, they possess unique properties and functions, and are commonly used as reinforcement in reinforced soil structures or composite materials. Geogrids are classified into four main categories: plastic geogrids, steel-plastic geogrids, fiberglass geogrids, and polyester warp-knitted geogrids. Geogrids are two-dimensional meshes or three-dimensional mesh screens with a certain height, made from polymers such as polypropylene and polyvinyl chloride through thermoplasticizing or molding. When used in civil engineering, they are called geogrids. Plastic geogrids are polymer mesh materials with square or rectangular shapes formed through stretching. Currently, based on the stretching direction during manufacturing, they can be classified into uniaxial and biaxial stretching types.

[0003] Uniaxial geogrid is a high-strength geosynthetic material made primarily of high-molecular polymers with added UV-resistant and anti-aging additives. Through uniaxial stretching, the originally randomly distributed chain molecules are reoriented into a linear state. The resulting sheet is extruded into a thin plate, punched with regular perforations, and then stretched longitudinally. Uniaxial geogrids are made by stretching only along the length of the sheet; biaxial geogrids are made by further stretching the uniaxially stretched geogrid in a direction perpendicular to its length.

[0004] Biaxially oriented geogrids can be stretched in both the transverse and longitudinal directions to form square through-holes, providing good tensile strength in both directions. However, the other angles of these square through-holes lack effective tensile structures, resulting in unsatisfactory overall tensile strength and stability. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-directional suspended geogrid. This geogrid employs multi-directional tension, which provides tensile strength at multiple angles. Furthermore, it features a structure with protruding grid sections to increase the contact area with the fill material, thereby enhancing stability and effectively solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-directional suspended geogrid, comprising several connected rectangular units, each rectangular unit being formed by directional stretching of 8 nodes, an elliptical protrusion being provided at the center of the rectangular unit, and strip-shaped ribs being provided on the upper, lower, left and right sides of the elliptical protrusion toward the midpoint of the side of the rectangular unit, so that the elliptical protrusion forms 4 square structures around it, each square structure having opposite triangular through holes on the upper and lower sides, and trapezoidal through holes on the left and right sides.

[0007] As a preferred technical solution, each rectangular unit of the geogrid forms a mesh structure consisting of 17 through holes.

[0008] As a preferred technical solution, the thickness of the elliptical protrusion is greater than the thickness of the other structures of the rectangular unit.

[0009] As a preferred technical solution, the rectangular unit has three nodes evenly distributed on each side.

[0010] As a preferred technical solution, the thickness of the node is greater than the thickness of the other structures of the rectangular unit.

[0011] As a preferred technical solution, the outline of the elliptical protrusion has a stretched and tortuous linear structure.

[0012] As a preferred technical solution, the square structure has a rectangular rib at its center, the inner ends of the upper and lower triangular through holes are respectively connected to the short side of the rectangular rib, and the left and right trapezoidal through holes are respectively connected to the long side of the rectangular rib.

[0013] As a preferred technical solution, the nodes are all cylindrical.

[0014] Compared with the prior art, this utility model provides a multi-directional suspended geogrid, which has the following beneficial effects: 1. This utility model features elliptical protrusions with strip-shaped ribs pointing towards the midpoints of the sides of rectangular units, forming four square structures around the elliptical protrusions. Each square structure has opposing triangular through holes at the top and bottom, and trapezoidal through holes on the left and right sides. The rectangular units form a mesh structure with 17 through holes. In use, the multiple ribs in different directions allow the geogrid to have good tensile strength at multiple angles, improving the overall tensile performance of the geogrid. Furthermore, the multi-hole structure of this geogrid saves material costs and reduces energy consumption. Especially when used in coastal and desert areas, it can be more comprehensively and multi-directionally embedded into the ground material to improve structural stability and durability, extend the design service life, and enable rapid construction under various engineering conditions, shortening process time and helping projects to be completed and put into operation quickly. In particular, when used with non-woven fabrics, it can better filter water and act as a reinforcing rib.

[0015] 2. In this utility model, the thickness of the elliptical protrusion is greater than the thickness of the other structures of the rectangular unit. Three nodes are evenly provided on each side of the rectangular unit, and the thickness of the nodes is greater than the thickness of the other structures of the rectangular unit. When in use, the elliptical protrusion and the nodes protrude from both sides of the geogrid, which can increase the contact area with the filler material in the construction environment, avoid vertical movement, and help the entire geogrid to be in a "suspended" state, thus enhancing stability.

[0016] 3. This utility model features a rectangular rib at the center of a square structure. The inner ends of the upper and lower triangular through holes are connected to the short sides of the rectangular rib, and the left and right trapezoidal through holes are connected to the long sides of the rectangular rib. In use, the rectangular rib can increase the connection strength at the center of the structure, which helps to improve the tensile strength of the entire geogrid. Attached Figure Description

[0017] The accompanying drawings, which are provided to further illustrate the present invention, constitute a part of this invention: Figure 1 This is a top view of the structure of this utility model; Figure 2 for Figure 1 A magnified structural diagram of a rectangular unit.

[0018] The diagram shows: 1. Rectangular unit; 11. Node; 2. Square structure; 21. Triangular through hole; 22. Trapezoidal through hole; 3. Rectangular rib; 4. Elliptical protrusion; 5. Strip rib. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] like Figure 1 , Figure 2 As shown, a multi-directional suspended geogrid includes several interconnected rectangular units 1 (within the dashed frame). Each rectangular unit 1 is formed by directional stretching of 8 nodes 11. An elliptical protrusion 4 (hollow frame) is located at the center of each rectangular unit 1. Strip-shaped reinforcing bars 5 are provided on the top, bottom, left, and right sides of the elliptical protrusion 4, facing the midpoints of the sides of the rectangular unit 1, thus forming four square structures 2 around the elliptical protrusion 4. Each square structure 2 has opposing triangular through holes 21 at the top and bottom, and trapezoidal through holes 22 on the left and right sides. The geogrid is made of polypropylene sheet material with integral perforation, processed by directional stretching of different square shapes.

[0021] Each rectangular unit 1 of the geogrid forms a mesh structure consisting of 17 through holes.

[0022] The thickness of the elliptical protrusion 4 is greater than the thickness of the other structures in the rectangular unit 1.

[0023] Each side of the rectangular unit 1 has three nodes 11 evenly distributed (the nodes at the corners are shared). Each node 11 is cylindrical.

[0024] The thickness of node 11 is greater than the thickness of the other structures in rectangular element 1.

[0025] The outline of the elliptical protrusion 4 has a stretched, tortuous linear structure.

[0026] The square structure 2 has a rectangular rib 3 at its center. The inner ends of the upper and lower triangular through holes 21 are connected to the short sides of the rectangular rib 3, and the left and right trapezoidal through holes 22 are connected to the long sides of the rectangular rib 3.

[0027] In use, multiple through holes form multiple ribs in different directions. These ribs allow the geogrid to have good tensile strength at multiple angles, improving its overall tensile performance and reducing the amount of polypropylene granules used in production. This reduces costs, lowers energy consumption, and saves material costs while achieving the same effect. Especially in coastal and desert areas, it can be more comprehensively and multi-directionally embedded in the soil material to improve structural stability and durability, extend its design service life, and enable rapid construction under various engineering conditions, shortening process time and facilitating quick project completion and commissioning. In particular, when used with non-woven fabric (laid on one or both sides), it can better filter water and act as a reinforcing rib. The elliptical protrusions 4 and nodes 11 increase the contact area with the fill material in the construction environment, preventing vertical movement and helping the entire geogrid to remain in a "floating" state. The rectangular ribs 3 increase the connection strength at the center of the directional structure, which helps improve the tensile strength of the entire geogrid.
