Description

Technical Field

[0001] The utility model relates to the field of slope support, in particular to a steep slope support system. Background Art

[0002] High and steep slopes are prone to landslides due to rainfall infiltration during the flood season. The original slope foot support cannot guarantee the overall stability of the high and steep slope. In order to ensure the safety of the slope and its surrounding environment, it is necessary to take protective measures such as support or reinforcement for the slope.

[0003] For example, the Chinese patent document with publication number CN116815785A discloses a foundation pit side support structure, including horizontal plates and vertical bars, which are combined to form a grid-shaped structure, the lower end of the horizontal plate is inserted into the slope, and the vertical bars are located on the surface of the slope to fix the support structure in the slope. This support structure can improve the effect of supporting steep slopes and avoid slope slippage and soil erosion.

[0004] However, although the support structure can support steep slopes, it has some technical defects. In the event of a large landslide, the vertical rods in the above support structure are only located on the surface of the slope to cooperate with the fixed cross plates, and the slope is not reinforced. In the support structure, only the lower end of the cross plate is inserted into the slope to fix the support structure to the steep slope, and there is no other reinforcement structure. When the impact of the landslide soil is large, since the fixation between the support structure and the slope is not firm, and the support structure is single, it cannot block and bear the impact force brought by the landslide soil, and it is very easy to loosen and fall off and collapse with the slope. Utility Model Content

[0005] The purpose of the utility model is to provide a combined slope support system, which can not only make the support structure more stably fixed on the slope, but also perform segmented combined support on the slope, thereby providing more stable support for the slope.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A combined support system suitable for steep rock slopes comprises a primary protective wall and a secondary protective wall, wherein the primary protective wall comprises a plurality of columns and plug plates inserted between adjacent columns, wherein the columns are fixed to the slope by a first anchor rod; the secondary protective wall comprises a steel mesh, wherein the steel mesh is fixed to the slope by a second anchor rod; in vertical space, the primary protective wall is arranged above the secondary protective wall.

[0008] The primary protective retaining wall is arranged above the secondary protective wall, the primary protective wall is composed of a plurality of columns with intervals, and the plug plate is inserted between two adjacent columns. The anchor rod 1 is fixedly connected to the column and the slope; the secondary protective retaining wall is fixedly connected to the steel mesh and the slope by the anchor rod 2.

[0009] The support system is composed of a combined support wall. The primary protective wall is connected to the slope through the anchor rod 1. The anchor rod 1 is fixedly connected to the column and inserted into the interior of the slope. The length of the anchor rod 1 can be set according to the material of the slope, so that the primary protective wall is more tightly fixed to the slope. The fixing principle of the secondary protective wall is the same as above. The primary protective wall is composed of the column and the plug plate. When a large landslide disaster occurs, the protection system composed of the column structure supports the slope, bears the impact force brought by the soil, and provides a fixed supporting force for the slope. The secondary protective wall is composed of the steel mesh, which covers and reinforces the slope over a large area, thereby increasing the structural stability of the slope. Through the reinforcement of the secondary protective wall, the structure of the slope with a larger slope and a larger area can be reinforced and protected.

[0010] The combined support wall can provide sufficient support force for the steep slope under the support and reinforcement effect. At the same time, the anchor rod is used to penetrate into the slope, making the first-level protection wall and the slope more stable. The fixing principle of the second-level protection wall is the same as above. This can avoid disasters such as landslides when a large landslide occurs.

[0011] As a preferred embodiment of the present invention, one side of the plug board is inserted into the slope body.

[0012] The plug plate is inserted into the slope body near one end of the slope body, so that the slope body and the inclined plug plate are fixedly connected, and the primary protective wall and the slope body are more tightly connected.

[0013] As a preferred embodiment of the utility model, a reinforcing rib band is provided between the steel mesh and the second anchor rod, and the steel mesh and the second anchor rod are welded and fixed by the reinforcing rib band.

[0014] By adding the reinforcing ribs between the steel mesh and the second anchor rod, the steel mesh and the second anchor rod are welded and fixed by the reinforcing ribs, so that the three become a whole, and by inserting the second anchor rod into the slope, the prefabricated fixed steel mesh is more firmly connected to the slope, thereby increasing the protective effect of the steel mesh.

[0015] As a preferred embodiment of the present invention, a bottom plate for supporting the columns is provided on the slope.

[0016] The slope structure is composed of rocks, soil and vegetation, and the structure is unstable. The soil is prone to loss after being washed by rainwater. In order to prevent the columns set on the slope from shaking or loosening, a bottom plate for supporting the columns is set on the slope. The bottom plate is cast with cement, which can provide stable supporting force for the columns. The material structure of the bottom plate is stable and not easy to loosen or deform. In turn, it can provide a more stable and firm supporting force for the slope.

[0017] As a preferred embodiment of the present invention, the primary protective wall is perpendicular to the horizontal plane in the vertical direction and is fixed to the slope.

[0018] The primary protective wall is vertically set on the slope. The primary protective wall in a vertical state can resist the hazards caused by landslides to the greatest extent. The spatial distance formed between the mountain and the primary protective wall can block part of the landslide mountain, so that the gravel and soil cannot directly roll down to the bottom of the mountain, thereby reducing the hazards caused by the landslide.

[0019] As a preferred embodiment of the present invention, grass seed geobags are laid on the steel mesh.

[0020] By placing the geobags filled with grass seeds between the grid gaps of the steel mesh, the grass seeds can take root and sprout in the geobags. The green plants that grow out strengthen the connection between the steel mesh and the slope, and the roots and stems of the green plants are used to fix the soil, reduce the probability of landslides, and improve the natural environment.

[0021] As a preferred embodiment of the present invention, green plants are provided on the surface of the plug board.

[0022] Green plants are planted on the upper surface of the plug plate. By planting green plants, the connection between the plug plate and the primary protective retaining wall composed of the columns is made tighter and more firm, which provides a more stable supporting force for the slope and stabilizes the structure of the slope to reduce the probability of natural disasters.

[0023] As a preferred embodiment of the present invention, a masonry body for supporting the steel mesh is provided near the bottom of the slope.

[0024] The masonry body is arranged at the bottom of the slope, and the masonry body can provide support force for the steel mesh. The steel mesh itself has a certain weight, and the slope has an inclination angle. The steel mesh is attached to the surface of the slope. At this time, the masonry body is arranged near the bottom of the slope to provide support force for the steel mesh, so that the steel mesh is better attached to the surface of the slope. The steel mesh will not be displaced due to its own excessive weight, and it is better attached to the surface of the slope to provide support for the slope to the greatest extent.

[0025] In summary, the utility model has the following beneficial effects:

[0026] 1. By placing geotextile bags filled with grass seeds between the grid gaps of the steel mesh, the roots of green plants are used to consolidate the soil, reduce the probability of landslides, and improve the natural environment.

[0027] 2. A bottom plate for supporting the columns is provided on the slope, which can provide a more stable and firm supporting force for the slope.

[0028] 3. By adding a reinforcing belt between the steel mesh and the second anchor rod, the three become a whole, and the second rod is inserted into the slope, so that the prefabricated fixed steel mesh is more firmly connected to the slope, thereby increasing the protective effect of the steel mesh.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0034] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0035] The primary protective retaining wall is arranged above the secondary protective wall, and the primary protective wall is composed of a plurality of columns 1 with a spacing, and the plug plate 2 is inserted between two adjacent columns 1. The anchor rod 1 4 is fixedly connected to the column 1 and the slope 3; the secondary protective retaining wall is fixedly connected to the steel mesh 5 and the slope 3 by the anchor rod 2 6.

[0036] The support system is composed of a combined support wall. The primary protective wall is connected to the slope 3 through the anchor rod 4. The anchor rod 4 is fixedly connected to the column 3 and inserted into the slope 3. The length of the anchor rod 4 can be set according to the material of the slope 3, so that the primary protective wall is more tightly fixed to the slope 3. The fixing principle of the secondary protective wall is the same as above. The primary protective wall is composed of the column 3 and the plug plate 2. When a large landslide disaster occurs, the protection system composed of the column structure supports the slope 3, bears the impact force brought by the soil, and provides a fixed supporting force for the slope 3. The secondary protective wall is composed of the steel mesh 5, which covers and reinforces the slope 3 over a large area to increase the structural stability of the slope 3. Through the reinforcement of the secondary protective wall, the structure of the slope 3 with a large slope and a large area can be reinforced and protected.

[0037] The combined support wall can provide sufficient support force for the steep slope under the support and reinforcement, and the anchor rod 4 is used to penetrate into the slope 3, so that the first-level protection wall and the slope 3 are more stable, and the fixing principle of the second-level protection wall is the same as above. This can avoid disasters such as landslides when a large landslide occurs.

[0038] The end of the plug plate 2 close to the slope body 3 is inserted into the slope body 3, so that the slope body 3 and the inclined plug plate are fixedly connected, making the primary protective wall and the slope body 3 more tightly connected.

[0039] By adding the reinforcing ribs between the steel mesh 5 and the anchor rod 6, the steel mesh 5 and the anchor rod 6 are welded and fixed by the reinforcing ribs, so that the three become a whole, and the anchor rod 6 is inserted into the slope 3 by inserting the prefabricated fixed connection steel mesh 5 to the slope 3 more firmly, thereby increasing the protective effect of the steel mesh 5.

[0040] The slope 3 is composed of rocks, soil and vegetation, and the structure is unstable. The soil is easy to flow away after being washed by rainwater. In order to prevent the pillars 1 arranged on the slope 3 from shaking or loosening, a bottom plate 7 for supporting the pillars 1 is arranged on the slope 3. The bottom plate 7 is cast by cement and can provide a stable supporting force for the pillars 1. The material structure of the bottom plate 7 is stable and not easy to loosen and deform. In addition, it can provide a more stable and firm supporting force for the slope 3.

[0041] The primary protective wall is vertically set on the slope 3. The primary protective wall in a vertical state can resist the hazards caused by landslides to the greatest extent. The spatial distance formed between the mountain and the primary protective wall can block part of the landslide mountain, so that the gravel and soil cannot directly roll down to the bottom of the mountain, thereby reducing the hazards caused by the landslide.

[0042] By placing the geotextile bag with grass seeds in the mesh gaps of the steel mesh 5, the grass seeds can take root and sprout in the geotextile bag. The green plants that grow strengthen the connection between the steel mesh 5 and the slope 3, and the roots and stems of the green plants are used to fix the soil, reduce the probability of landslides, and improve the natural environment.

[0043] Green plants are planted on the upper surface of the plug board 2. By planting green plants, the connection between the plug board 2 and the primary protective retaining wall composed of the column 1 is made tighter and more firm, which provides a more stable supporting force for the slope 3 and stabilizes the structure of the slope 3 to reduce the probability of natural disasters.

[0044] The masonry body 8 is arranged at the bottom of the slope 3, and the masonry body 8 can provide support force for the steel mesh 5. The steel mesh 5 itself has a certain weight, and the slope 3 has an inclined angle. The steel mesh 5 is attached to the surface of the slope 3. At this time, the masonry body 8 is arranged at the bottom of the steel mesh 5 close to the slope 3 to provide support force for the steel mesh 5, so that the steel mesh 5 is better attached to the surface of the slope 3. The steel mesh 5 will not be displaced due to its own excessive weight, and is better attached to the surface of the slope 3 to provide support for the slope 3 to the greatest extent.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
