[0006] Further, the grid adopts an equilateral hexagonal structure, and a plurality of hollows are provided in the interior of the grid, which facilitates weight reduction of the main body, saves production materials to a certain extent, and reduces costs.
[0007] Further, a plurality of tapered pins are provided on the lower surface of the reinforcing plate, which can be embedded into the soil when the grid is laid in the soil.
[0008] Further, a clamping column for inserting into the interior of the grid is provided on the upper surface of the reinforcing plate, a fixing groove is provided at one end of the reinforcing plate, and a protrusion for embedding into the interior of the fixing groove is provided below the grid, and the clamping column and the grid and the fixing groove and the protrusion below the grid can form a tight mechanical embedding, thereby ensuring the connection between the reinforcing plate and the grid.
[0009] Further, a reinforcing ring with a circular structure is embedded on the upper surface of the clasp ring, and the reinforcing ring and the reinforcing plate are both made of aluminum alloy plates, which can increase the connection strength between adjacent gratings.
[0010] Compared with the prior art, the utility model has the beneficial effects that:
[0011] The utility model discloses an equal-sided polygon structure and internal triangular hollow design, which can reduce weight, save materials and cost, and make each part of the grating cooperate in multiple directions, so that each edge and area of the grating can support each other when facing external force in different directions. Meanwhile, an arc-shaped clamping groove is arranged at each corner of the grating. When adjacent gratings are spliced, the clamping grooves can be accurately aligned with each other, and then the clamping ring is clamped into the clamping groove during installation, so that the connection between adjacent gratings can be easily completed, and the whole operation process is very convenient.
[0012] The utility model discloses that the clamping column on the reinforcing plate and the convex part below the grating can achieve a close and stable mechanical fitting state, which can enhance the strength of the corner part of the grating, so that the grating can still maintain good integrity when bearing large external forces such as tension and shear force.
[0013] The aluminum alloy reinforcing ring embedded on the clasp ring cooperates with the clamping column on the reinforcing plate and synergistically exerts force, which further strengthens the connection strength between adjacent gratings. A plurality of tapered insertion pins are arranged on the lower surface of the reinforcing plate. When the geogrid is laid in the soil, the insertion pins can be embedded in the soil, avoiding the relative sliding between the geogrid and the soil during the stress process.

Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the utility model.
[0024] As shown in the accompanying drawings. Figures 1-7
[0025] A novel multidirectional geogrid, comprising a grid 1 in the shape of an equilateral polygon structure, preferably an equilateral hexagonal structure, a triangular hollow is arranged in the interior of the grid 1, which facilitates the weight reduction of the main body, and also can save the manufacturing material to a certain extent and reduce the cost; the polygon structure enables the coordination of each part and each edge in multiple directions, so that each edge and each area can be related and supported to each other and jointly play a role when the entire grid faces external force in different directions.
[0026] An arc-shaped snap groove 11 is arranged at each corner of the grid 1, and after the adjacent two grids 1 are spliced, the adjacent snap grooves 11 can be combined to finally form a ring structure.
[0027] After the snap grooves 11 in the adjacent grids 1 are combined, the snap ring 2 is clamped in the snap groove 11, which can realize the connection of the adjacent grids 1.
[0028] A reinforcing plate 3 is arranged below the grid 1 and at each corner, and the mounting mode of the reinforcing plate 3 can be adhesion or fusion.
[0029] The reinforcing plate 3 is made of aluminum alloy plate, which does not excessively increase the self-weight of the overall structure, is convenient for construction and laying, and after the reinforcing plate 3 is connected with the grid 1, the grid 1 can be locally reinforced to form a firm connection point similar to a joint. This node can still maintain good integrity when bearing large tension and shear force, and is not prone to damage.
[0030] A plurality of conical pins 31 are arranged on the lower surface of the reinforcing plate 3, which can be embedded into the soil when the grid is laid in the soil, tightly hold the surrounding soil particles like "claws", and greatly enhance the bonding force with the soil, effectively avoiding relative sliding during the stress process.
[0031] A clamping column 32 for inserting into the interior of the grid 1 is arranged on the upper surface of the reinforcing plate 3, a fixing groove 33 is arranged at one end of the reinforcing plate 3, and a protrusion for embedding into the interior of the fixing groove 33 is arranged below the grid 1, as shown in the accompanying drawings. Figure 2 、 3 As shown in the accompanying drawings, the clamping column 32 and the protrusion below the grid 1 can form a tight mechanical embedding between the fixing groove 33 and the grid 1, which ensures the connection between the reinforcing plate 3 and the grid 1, and ensures that they can work cooperatively during the stress process, and maintain the integrity of the overall structure of the geogrid; meanwhile, the clamping column 32 can increase the strength of the corners of the grid 1, and enhance the ability of the corners to resist damage.
[0032] Further, a reinforcing ring 21 in a circular ring structure is embedded on the upper surface of the clamping ring 2, which is also made of aluminum alloy, and under the joint action of the reinforcing ring 21 and the clamping column 32, the connection strength between adjacent grids 1 can be increased.
[0033] The use mode of the device is as follows: before laying, the construction site needs to be cleaned and leveled to ensure that the ground is free of sharp debris, stones and the like, so as to avoid damaging the geogrid, and at the same time, according to the design requirements of the project, the laying range and direction of the geogrid are measured and determined.
[0034] According to the size of the geogrid required by the actual project, the single grid 1 is spliced. The clamping grooves 11 of adjacent grids 1 are aligned and combined into a ring structure, and then the clamping ring 2 is clamped into the clamping groove 11, so that the connection between adjacent grids is completed. During this process, it is necessary to check whether the clamping ring is completely embedded in the clamping groove, so as to ensure that the connection is tight and firm.
[0035] During the laying process, the pins 31 on the lower surface of the reinforcing plate 3 are naturally embedded into the soil; if the pins are difficult to insert due to hard soil, small tools can be used to pre-drill holes on the surface of the soil before laying, so that the pins can be firmly embedded between the soil particles and the bonding force with the soil is enhanced.
[0036] The technical scheme of the utility model or the technical scheme inspired by the technical personnel in the art of the utility model can be used to design similar technical schemes to achieve the above technical effects, which are all within the protection scope of the utility model.
