Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope reinforcement technology, specifically a geotechnical engineering slope reinforcement structure. Background Technology
[0002] Geotechnical slope protection devices are designed to prevent landslides from damaging the underlying structures on and below the slope. Specifically, during a landslide, the slope sinks while the area below is buried. Typically, there are roads on both sides of the slope; a landslide will cause the upper road surface to sink and the lower road surface to be buried. Therefore, slope protection is extremely important, playing a crucial role in soil stabilization and protection. However, currently used geotechnical slope protection and reinforcement devices mainly consist of precast concrete slabs fixed to the slope surface with anchors. While this method is simple, it is unstable. According to stress analysis, the heavy precast concrete slabs will generate a sliding force along the slope surface, which is mainly borne by the anchors. Therefore, the anchors must withstand not only the downward force of the soil and rock but also the sliding force of the precast concrete slabs. Although the soil surface at the bottom of the precast concrete slabs provides some support, this surface is easily crushed by gravity, leading to subsidence. Furthermore, traditional slope protection and reinforcement devices consist entirely of precast concrete slabs, which deteriorates the ecological environment of the affected area. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a slope reinforcement structure for geotechnical engineering, addressing the above-mentioned shortcomings.
[0004] To solve the above technical problems, the present invention adopts the following technical solution:
[0005] A geotechnical slope reinforcement structure includes multiple support columns, an upper concrete frame, and a lower concrete frame. The support columns are vertically inserted into the bottom of the slope and extend to the outside of the slope. The upper and lower concrete frames are respectively laid on the upper and lower surfaces of the outer side of the slope and partially embedded in the slope. The lower concrete frame is cast and connected to the top of the support columns. The top of the lower concrete frame is fixedly connected to the upper concrete frame through connecting columns. Both the upper and lower concrete frames are rectangular plate-shaped frames. The cross-section of the upper concrete frame is narrower than that of the lower concrete frame, and the embedment depth of the upper concrete frame is deeper than that of the lower concrete frame.
[0006] Furthermore, the supporting columns are precast concrete columns, and each concrete column has an iron column at its axis that extends to the inner side of the lower concrete frame. A circular steel cage is provided inside the supporting column.
[0007] Furthermore, the bottom of the upper concrete frame is provided with a first concrete pile inserted into the inner side of the slope, and the bottom of the lower concrete frame is provided with a second concrete pile inserted into the inner side of the slope. Both the first and second concrete piles are perpendicular to the slope surface. The diameter of the first concrete pile is 50mm, and the diameter of the second concrete pile is 100mm. Both the first and second concrete piles are embedded with reinforcing bars.
[0008] Furthermore, the upper concrete frame has a cross-sectional width of 100mm, a height of 250mm, and a soil embedment depth of 200mm.
[0009] Furthermore, a square steel reinforcement cage is provided inside the lower concrete frame, and the upper concrete frame has a cross-sectional width of 200mm, a height of 200mm, and a soil embedment depth of 100mm.
[0010] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:
[0011] This utility model employs multiple support columns vertically inserted into the bottom of the slope, with upper and lower concrete frames laid on the upper and lower surfaces of the slope respectively. The lower concrete frame is cast and connected to the support columns. This changes the traditional method of simply relying on anchor rods to fix precast concrete slabs, disperses the stress, reduces the sliding force borne by a single anchor rod, effectively improves the stability of the overall structure, reduces the risk of structural failure due to stress concentration, and prevents the road surface above the slope from sinking and the road surface below the slope from being buried due to slope landslides.
[0012] The upper concrete frame has a narrow cross-section and is deeply embedded in the soil, while the lower concrete frame has a wide cross-section and is shallowly embedded in the soil. This design makes the structure more rationally stressed on the slope, better adapts to the stress characteristics of different parts of the slope, further enhances the reinforcement effect, and avoids the problem of the soil and rock surface being crushed and subsided due to unreasonable stress on traditional heavy precast concrete slabs.
[0013] Unlike traditional slopes where the entire slope is covered by precast concrete slabs, this structure reduces the area covered by concrete through a reasonable frame layout, thereby minimizing damage to the slope's ecological environment, maintaining the relative stability of the slope's ecosystem, and promoting sustainable development of the ecological environment.
[0014] Iron columns 5 are set at the axis of the support column 1. Concrete piles inserted into the slope are set at the bottom of the upper and lower concrete frames 3 and filled with reinforcing bars. A square steel cage 8 is set on the inner side of the lower concrete frame 3. The strength and resistance to damage of the structure are enhanced in many ways, and the service life and reliability of the slope reinforcement structure are improved.
[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0022] like Figure 1-2 As shown, a geotechnical slope reinforcement structure includes multiple support columns 1, an upper concrete frame 2, and a lower concrete frame 3. The multiple support columns 1 are vertically inserted into the bottom of the slope and extend to the outside of the slope. The upper concrete frame 2 and the lower concrete frame 3 are respectively laid on the upper and lower surfaces of the outer side of the slope and partially embedded in the slope. The lower concrete frame 3 is cast and connected to the top of the multiple support columns 1. The top of the lower concrete frame 3 is fixedly connected to the upper concrete frame 2 by a connecting column 4. Both the upper concrete frame 2 and the lower concrete frame 3 are rectangular plate-shaped frames. The cross-section of the upper concrete frame 2 is narrower than the cross-section of the lower concrete frame 3, and the embedment depth of the upper concrete frame 2 is deeper than that of the lower concrete frame 3.
[0023] In one embodiment, the support column 1 is a precast concrete column, and each concrete column has an iron column 5 at its axis extending to the inner side of the lower concrete frame 3. A circular steel cage 9 is provided inside the support column 1.
[0024] In one embodiment, the bottom of the upper concrete frame 2 is provided with a first concrete pile 6 inserted into the inner side of the slope, and the bottom of the lower concrete frame 3 is provided with a second concrete pile 7 inserted into the inner side of the slope. Both the first concrete pile 6 and the second concrete pile 7 are perpendicular to the slope surface. The diameter of the first concrete pile 6 is 50mm, and the diameter of the second concrete pile 7 is 100mm. Both the first concrete pile 6 and the second concrete pile 7 are embedded with reinforcing bars.
[0025] In one embodiment, the upper concrete frame 2 has a cross-sectional width of 100mm, a height of 250mm, and a soil embedment depth of 200mm.
[0026] In one embodiment, a square steel cage 8 is provided inside the lower concrete frame 3, and the upper concrete frame 2 has a cross-sectional width of 200mm, a height of 200mm, and a soil depth of 100mm.
[0027] The workflow of this utility model is as follows: A suitable location is determined at the bottom of the slope, and multiple concrete support columns 1 are vertically inserted into the bottom of the slope to ensure the stability of the support columns 1 and provide foundation support for subsequent structures. Simultaneously, an iron column 5 is installed at the axis of the concrete column, with its top extending to the inner side of the lower concrete frame 3, to enhance the strength of the support column 1.
[0028] On the slope, trenches are excavated corresponding to the upper concrete frame 2, connecting column 4, and lower concrete frame 3. Then, a 50mm pouring hole for the first concrete pile 6 is excavated in the trench corresponding to the upper concrete frame 2, and a 100mm pouring hole for the second concrete pile 7 is excavated in the trench corresponding to the lower concrete frame 3. Reinforcing bars are installed inside the pouring holes. Then, a pouring formwork is laid inside the trench, and a square steel cage 8 is placed inside the lower concrete frame 3. The lower end formwork of the lower concrete frame 3 covers the top of the support column 1. The top of the iron column 5 extends to the inside of the square steel cage 8. Finally, concrete is poured into the inside of the formwork to simultaneously and integrally cast the upper concrete frame 2, connecting column 4, lower concrete frame 3, first concrete pile 6, second concrete pile 7, and the top of the support column 1. After the concrete hardens, the formwork can be removed for normal use.
[0029] Based on the actual slope conditions, ensure that the upper concrete frame 2 has a narrow cross-section and is deeply embedded in the soil, and the lower concrete frame 3 has a wide cross-section and is shallowly embedded in the soil, so as to achieve a reasonable stress distribution.
[0030] When a slope is subjected to various external forces such as its own weight, rainwater erosion, or earthquakes, and shows signs of landslide, the upper and lower concrete frames 3 and the supporting columns 1 work together. The upper concrete frame 2 transfers part of the force from the upper slope to the connecting column 4 and the lower concrete frame 3, while the supporting column 1 bears part of the pressure from the frame and the slope. This changes the situation in traditional structures where anchor rods bear the sliding force and soil collapse force alone, thus distributing the force across the entire reinforced structure.
[0031] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
