Description

Technical Field

[0001] The utility model relates to the technical field of slope protection grids, in particular to a slope surface soil and water loss grid fixing part. Background Art

[0002] In the prior art, U-shaped ground spikes are generally used to fix the slope protection grid. However, U-shaped ground spikes are only suitable for fixing single-layer slope protection grids. They are usually difficult to use for multi-layer, elastic geogrids.

[0003] For example, for Figure 1 The slope protection grid in this system is thick and has a geotextile layer within it. Directly fixing it with U-shaped ground nails is blocked by the multi-layer structure and geotextile. This results in the nails not penetrating deeply into the soil and insufficient fixing effect. Furthermore, because the slope protection grid is fixed by a layered structure and adopts a flexible, wavy design in the middle, it is difficult to ensure the overall stability of the slope protection grid by only fixing the bottom grid with U-shaped ground nails. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to address the deficiencies of the existing technology and to propose a slope soil erosion grid fixing device. The technical solution provided by the present invention is as follows:

[0005] A slope surface soil erosion grid fixing piece comprises two mutually hinged fixing parts, sleeves are provided at both ends of the fixing parts, pressure arms are provided on the sides of the sleeves, and fixing nails are passed through the sleeves.

[0006] As an improvement, a connecting piece is provided in the middle of the fixing portion, a hinge hole is provided at the center of the connecting piece, and the two fixing portions are hinged to each other at the center position and form an X shape.

[0007] As an improvement, the side of the sleeve is fixedly connected to the end of the connecting piece, and the top of the sleeve is flush with the top of the connecting piece.

[0008] As an improvement, the pressing arm is L-shaped.

[0009] As an improvement, the pressure arms on the different fixing parts are arranged opposite to each other.

[0010] The advantages of this utility model are:

[0011] 1. Traditional U-shaped ground nails have difficulty achieving deep fixation when securing multi-layer or elastic geogrids due to the obstruction of the multi-layer structure and geotextile, resulting in insufficient fixing effect. However, the present invention, through the design of two mutually hinged fixing parts and a pressure arm on the side of the sleeve, can bypass the wavy biaxially stretched folding mesh to achieve deep fixation of multi-layer structures, thereby significantly improving the fixing effect.

[0012] 2. This utility model not only fixes the bottom grid, but also the elastic wave-shaped structure in the middle. At the same time, the X-shaped structural design enables the fixing parts to provide support from multiple directions, enhancing the overall stability of the slope protection grid and effectively preventing the grid from moving or wrinkling.

[0013] 3. During the fixing process, the fixing nails pass through the sleeve and are inserted into the soil layer, leaving only small holes on the geotextile, which can effectively reduce the damage to the geotextile and ensure the use effect of the geotextile and the functionality of the grid.

[0027] This embodiment discloses a slope soil and water loss grid fixing member.

[0028] This embodiment is aimed at fixing the slope protection grid with a multi-layer structure. Figure 1 As shown, from top to bottom, it includes the top flat biaxially stretched grid, geotextile A, biaxially stretched folded net B and bottom flat biaxially stretched grid C; the top flat biaxially stretched grid, biaxially stretched folded net and bottom flat biaxially stretched grid are tied and fixed by binding ropes.

[0029] When using traditional U-shaped ground nails for fixing, it is difficult for the ground nails to fit the ground due to the obstruction of the upper structure, resulting in the ground nails not being deeply embedded in the ground, the fixing effect is not strong, and it is easy to fall out of the soil.

[0030] This embodiment includes two mutually hinged fixing parts 1 , with sleeves 2 provided at both ends of the fixing parts 1 , pressure arms 3 provided on the sides of the sleeves 2 , and fixing nails 4 passing through the sleeves 2 .

[0031] A connecting piece 11 is provided in the middle of the fixing part 1 , and a hinge hole 12 is provided at the center of the connecting piece 11 . The two fixing parts 1 are hinged to each other at the center and form an X shape.

[0032] The sides of the sleeve 2 are fixedly connected to the ends of the connecting piece 11, and the top of the sleeve 2 is flush with the top of the connecting piece 11. The height of the sleeve 2 is no higher than the height of the wavy biaxially stretched folded mesh B, and it can be inserted into the grid through the gaps in the biaxially stretched folded mesh B. The sleeve 2 is then inserted into the soil for pre-fixation.

[0033] The pressing arms 3 are L-shaped, and the pressing arms 3 on different fixing parts 1 are arranged opposite each other. As shown in the figure, the pressing arms 3 on the left and right sides are arranged opposite each other. As shown in the figure, the pressing arms 3 can pass around the wavy biaxially stretched folded mesh B and compress and secure it. This solves the problem that traditional ground spikes can only secure the bottom flat biaxially stretched grid C, but cannot secure the biaxially stretched folded mesh B.

[0034] After the fixing member 1 is fixed, the fixing nail 4 is inserted through the sleeve 2 to complete the final fixation. When the fixing nail 4 is inserted, it will only leave a small hole on the geotextile A, which will not affect the use effect of the geotextile A.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
