Description

Technical Field

[0001] This utility model relates to the field of soil stabilization grids, specifically to a soil stabilization grid for highway slopes. Background Technology

[0002] Soil stabilizing grids, as an important component of slope protection, are usually composed of multiple honeycomb grids. Their grid structure anchors the surface soil particles of the slope, effectively reducing the loss of surface soil caused by rainwater erosion.

[0003] In actual construction, soil stabilization geogrids need to be laid on the slope surface by connecting multiple geogrid units. However, the connection methods of adjacent geogrid units in the existing technology have obvious defects: when using simple rope binding or rivet fixing, the strength of the connection part is often insufficient to meet the engineering requirements; due to the complex slope environment, the geogrid needs to withstand various external forces such as soil displacement and water erosion, especially at the overlapping parts, where large tensile stress and shear force will be generated. Under the traditional connection method, the overlapping parts are prone to deformation or even breakage, which not only affects the stability of the overall structure, but also causes local mesh deformation and displacement, ultimately weakening the protective effect of the entire soil stabilization geogrid system.

[0004] Furthermore, the positioning methods of existing geogrid units on slopes are not reliable enough, and they are prone to local loosening or displacement during long-term use, further affecting slope stability. These problems severely restrict the application effectiveness and service life of soil stabilization geogrids in highway slope protection projects. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a soil stabilization grid for highway slopes.

[0006] This utility model is achieved through the following technical solution:

[0007] A type of slope stabilization grid for highways includes several adjacent grid unit bodies placed on the slope. Multiple connecting ropes are longitudinally threaded through the overlapping joints of multiple connecting pieces on both sides of the adjacent grid unit bodies. An arched positioning frame for supporting the overlapping joints of the connecting pieces is clamped onto the multiple connecting ropes. Positioning nails are inserted into the connecting joints of multiple honeycomb grids of the grid unit body.

[0008] Alternatively, the bow-shaped positioning frame includes an upper arc plate and a lower arc plate connected vertically. The lower part of the upper arc plate has multiple lower insertion holes for corresponding connecting ropes to pass through, and the upper part of the lower arc plate has multiple upper insertion holes arranged in a stepped manner with the lower insertion holes.

[0009] Alternatively, the lower part of the upper and lower arc plates is fixed with multiple positioning rods that are inserted into the inside of the slope.

[0010] Alternatively, several limiting serrations may be provided on the inner sides of the lower and upper insert holes.

[0011] Alternatively, the positioning pin includes four positioning rods that are inserted into the top, bottom, left, and right of adjacent honeycomb grid connection points, with the top of the positioning rods connected via a connecting plate.

[0012] Alternatively, multiple pre-drilled holes for passing through connecting ropes are provided on multiple connecting plates on both sides of the grid unit body.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting arched positioning frames on both sides of the grid unit body on the slope to support the overlapping joints of the connecting pieces, and using multiple connecting ropes and positioning nails for fixing, this utility model effectively enhances the connection strength between adjacent grid units, improves the stability of the overall structure, and has the advantages of improving the connection strength between adjacent grid units, enhancing the stability of the overall structure, and improving the long-term reliability of use.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1-2 As shown, this application proposes a slope stabilization grid for highways, including several adjacent grid unit bodies placed on the slope. Multiple connecting ropes are longitudinally threaded through the corresponding overlapping joints of multiple connecting pieces on both sides of the adjacent grid unit bodies. An arched positioning frame for supporting the overlapping joints of the connecting pieces is snapped onto the multiple connecting ropes. Positioning nails are inserted into the multiple honeycomb grid connection joints of the grid unit bodies.

[0020] Specifically, the grid unit body adopts a honeycomb mesh structure, and multiple units are spliced ​​together to form an overall covering layer. Connecting plates are set on both sides of the grid unit body, and adjacent units overlap each other through the connecting plates. The connecting rope can be made of high-strength nylon rope, which runs longitudinally through multiple overlapping connecting plates. The bow-shaped positioning frame is preferably made of metal, and its curvature matches the shape of the overlapping part of the connecting plate. It is fixed to the connecting rope by snap-fit. The positioning nail can adopt a cross-shaped structure, with four inserts inserted into the connection points of adjacent honeycomb meshes, and the top is fixed by a connecting plate. As a preferred embodiment, an appropriate length can be reserved when the connecting rope is threaded to facilitate the adjustment of tension later.

[0021] This technical solution effectively enhances the tensile strength and shear resistance of the grid unit connections through the synergistic effect of connecting ropes and arched positioning frames. The connecting ropes bear the main tensile force, while the arched positioning frames distribute local stress and prevent deformation of the connecting pieces. The positioning pins improve the stability of the grid units on the slope, preventing local displacement. Compared to existing technologies, this solution significantly improves the structural strength of the connections, enabling the soil-stabilizing grid to withstand greater external forces while maintaining good overall stability. Therefore, the grid is less prone to deformation and damage during long-term use, ensuring the durability of the soil stabilization effect.

[0022] like Figure 3 As shown, this application further proposes that the bow-shaped positioning frame includes an upper arc plate and a lower arc plate connected vertically. The lower part of the upper arc plate has multiple lower insertion holes for passing through corresponding connecting ropes, and the upper part of the lower arc plate has multiple upper insertion holes arranged in a stepped manner with the lower insertion holes.

[0023] The upper and lower arc plates are fixed together by welding to form a stable arched structure. The lower and upper insert holes are arranged in a stepped pattern, allowing the connecting rope to interlock during installation. The thickness of the upper and lower arc plates can be adjusted according to actual stress requirements; for example, 3-5mm thick steel plates can be used to enhance structural strength. The diameter of the lower and upper insert holes is slightly larger than the diameter of the connecting rope, facilitating installation and allowing for minor displacement.

[0024] Specifically, this technical solution enhances the limiting effect on the connecting ropes through the upper and lower arc plate structure of the bow-shaped positioning frame, resulting in more uniform stress distribution at the joint of the connecting pieces. The stepped arrangement of the embedded holes prevents the connecting ropes from slipping under stress, thereby improving the tensile and shear strength of the joint. Compared with existing technologies, this structure can effectively reduce deformation and displacement at the grid connection, improving overall stability.

[0025] like Figure 3 As shown, this application further proposes that the lower part of the upper and lower arc plates is fixed with multiple positioning rods inserted into the inside of the slope.

[0026] The positioning rod can be made of metal, and its length is adjusted according to the slope soil conditions, typically 30-50 cm. The cross-sectional shape of the positioning rod can be circular, square, or other polygonal, and a threaded or barbed structure is preferred to enhance the anchoring effect.

[0027] Therefore, by installing positioning rods at the lower part of the bow-shaped positioning frame, the grid unit body can be more firmly fixed to the slope. Specifically, after the positioning rods are inserted into the slope, they can effectively resist the tensile and shear forces on the grid, preventing the grid unit body from shifting or deforming due to stress. The connection structure between the positioning rods and the bow-shaped positioning frame enhances overall stability, allowing the grid to evenly distribute stress when subjected to external forces, thereby improving soil stabilization and the long-term stability of the slope.

[0028] like Figure 3 As shown, this application further proposes that several limiting serrations are provided on the inner sides of the lower and upper insert holes.

[0029] The limiting serrations can be triangular, trapezoidal, or other shapes that increase friction. The serrations can be arranged continuously or intermittently. The height and density of the serrations can be adjusted according to the diameter and material of the connecting rope to ensure sufficient clamping force.

[0030] Specifically, by setting limiting serrations inside the lower and upper recesses where the connecting rope passes through, the friction between the connecting rope and the bow-shaped positioning frame can be effectively increased, preventing the connecting rope from slipping or shifting under stress. This ensures stability at the connection points of adjacent grid units, reducing deformation and displacement caused by external forces, thereby improving the overall fixation effect of the soil stabilization grid and the stability of the slope. Compared with existing technologies, this technical solution significantly enhances the tensile and shear strength of the connection points through simple structural improvements, solving the problem of large deformation at the grid connection points under stress.

[0031] like Figure 2 As shown, this application further proposes that the positioning pin includes four positioning rods inserted into the upper, lower, left, and right sides of the connection point of the adjacent honeycomb grid, and the top of the positioning rods is connected and set through a connecting plate.

[0032] Specifically, the lower end of the positioning pin is designed to be tapered for insertion into the soil. The connecting plate can be a flat plate or an arc-shaped plate. Furthermore, the surface of the connecting plate can be provided with anti-slip texture to enhance the friction with the grid unit. When arranging the positioning pins, they can be arranged in a staggered pattern or in a parallel multi-row, spaced-out arrangement.

[0033] This technical solution achieves omnidirectional fixation of the honeycomb grid connection points through a four-way distributed positioning rod structure. When the grid unit is subjected to external force, the four positioning rods can evenly distribute the force, effectively preventing deformation and displacement of individual connection points due to concentrated force. The connecting plate makes the positioning rods form an integral force-bearing structure, further enhancing the fixation stability. Compared with the traditional single-point fixing method, this design significantly improves the positioning effect of the grid unit on the slope and reduces the problem of overall structural deformation caused by localized forces.

[0034] like Figure 1 As shown, this application further proposes that multiple pre-drilled holes for connecting ropes to pass through are provided on multiple connecting plates on both sides of the grid unit body. The pre-drilled holes can be located at the edge or center of the connecting plates, and their diameter matches the diameter of the connecting rope to ensure smooth passage and stable connection. The shape of the pre-drilled holes can be circular, elliptical, or other suitable shapes, specifically designed according to the cross-sectional shape of the connecting rope and the stress requirements. The number of pre-drilled holes can be adjusted according to the length of the connecting plates and the stress requirements; typically, 2-4 pre-drilled holes on each connecting plate are preferable. The edges of the pre-drilled holes can be chamfered to reduce wear on the connecting ropes.

[0035] Specifically, by setting pre-drilled holes, the connecting rope can accurately pass through the connecting plate, preventing slippage or offset of the rope on the connecting plate, thereby ensuring the connection strength and stability between adjacent grid unit bodies. The pre-drilled holes make the installation of the connecting rope more convenient and quick, improving construction efficiency. At the same time, the reasonable design of the position and number of pre-drilled holes can effectively distribute the force at the connection point, reduce local stress concentration, and prevent the connecting plate from deforming or being damaged due to excessive force.
