Description

Technical Field

[0001] This utility model relates to an ecological protection structure for slopes, specifically an ecological protection structure for roadbed slopes that is seepage-proof and crack-resistant, belonging to the field of slope protection technology. Background Technology

[0002] A roadbed is the foundation for a railway track or road surface, and is an earthwork structure formed through excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track, locomotives, rolling stock, road surface, and traffic loads, while simultaneously transferring and dispersing the loads deeper into the foundation. In longitudinal profile, the roadbed must ensure the required elevation for the railway line. In civil engineering, the roadbed occupies an important position in terms of construction volume, land area, and investment.

[0003] A search revealed a Chinese patent with publication number CN218116502U, which discloses a roadbed slope protection structure, relating to the technical field of slope protection. The structure includes a water storage tank with a connecting post at the bottom; a protective frame with a connecting hole at the top for the connecting post; and a fixing assembly comprising an anchor rod inserted into the slope, a pressure plate fitted onto the anchor rod, and a nut threaded onto the top of the anchor rod. The nut tightens the pressure plate, fixing the protective frame to the slope. This application enhances slope protection and reduces soil erosion.

[0004] While the above solutions can reduce soil erosion on slopes, the slope protection structures in the aforementioned patents are not effective in protecting against falling rocks. Rocks rolling down from heights have enormous impact kinetic energy, and when they directly hit the protective substrate, they can easily cause the substrate to crack, break, or be dented, thus losing its protective function. Therefore, we provide a seepage-proof and crack-resistant ecological protection structure for roadbed slopes to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an ecological protection structure for roadbed slopes that is seepage-proof and crack-resistant in order to solve the above-mentioned problems, so as to solve the problem that it is difficult to effectively protect against falling rocks from heights in the existing technology.

[0006] This utility model is achieved through the following technical solution: an ecological protection structure for roadbed slope that is seepage-proof and crack-proof, including a protective box, a protective mechanism provided on the inner side of the protective box, the protective mechanism including a slide rail fixedly connected to the inner side of the protective box, a fixing block fixedly connected to the outer surface of the slide rail, a sliding rod fixedly connected to one side of the fixing block, a slider slidably connected to the outer surface of the sliding rod, a spring fixedly connected to one side of the slider, and the end of the spring away from the slider fixedly connected to one side of the fixing block;

[0007] A connecting rod is hinged to the other side of the slider, and a first buffer is hinged to the end of the connecting rod away from the slider. A protective plate is fixedly connected to the telescopic end of the first buffer.

[0008] Preferably, a second buffer is fixedly connected to one side of the slide rail, and the telescopic end of the second buffer is fixedly connected to one side of the protective plate. The second buffers on both sides can support the two sides of the protective plate, thus providing support.

[0009] Preferably, the other side of the slide rail is fixedly connected to the fixed end of the first buffer, and one side of the protective plate is slidably connected to the inner side of the protective box. The first buffer can fix the protective plate, and the protective plate can withstand the impact.

[0010] Preferably, the lower end of the protective box is fixedly connected to a slope protection frame, and a water guide channel is provided on one side of the slope protection frame. The slope protection frame is installed at the bottom of the slope to protect the slope.

[0011] Preferably, a fixing frame is fixedly connected to one side of the slope protection frame, and a drainage groove is provided on the inner side of the fixing frame. The fixing frame is installed on the slope protection frame, and the slope protection mesh can be installed through the fixing frame.

[0012] Preferably, the upper end of the fixing frame is fixedly connected to a slope protection top plate, and the lower side of the fixing frame is fixedly connected to an anchor rod. The slope protection top plate can protect the upper end of the slope and prevent rainwater from accumulating on the top of the slope, thus playing a protective role.

[0013] Preferably, a fixing shaft is fixedly connected to the inner wall of the fixing frame, and an installation frame is fixedly connected to the end of the fixing shaft away from the fixing frame. A slope protection mesh is fixedly connected to the inner side of the installation frame. The installation frame can be installed on the slope through the fixing shaft, and then the slope protection mesh can be installed on the installation frame to protect the slope and prevent the slope from collapsing.

[0014] This utility model provides an ecological protection structure for roadbed slopes that is seepage-proof and crack-resistant, and its beneficial effects are as follows:

[0015] 1. This slope ecological protection structure, through the coordinated use of sliding rails, fixed blocks, sliding rods, springs, sliders, connecting rods, first buffers, protective plates, and second buffers, utilizes a multi-stage linkage buffering mechanism to convert instantaneous strong impact force into the elastic potential energy of the springs and the damping energy dissipation of the buffers. This greatly reduces the impact force borne by the protective plate, effectively preventing the protective plate from cracking, breaking, or undergoing permanent deformation due to impact. It significantly improves the structure's impact resistance and durability, ensuring the long-term safety and stability of the roadbed slope, and effectively buffering and absorbing the enormous impact energy of falling rocks from heights.

[0016] 2. This slope ecological protection structure utilizes a combination of a slope protection frame, a drainage channel, a slope protection top plate, a fixing frame, a fixing shaft, an installation frame, a slope protection mesh, anchor bolts, and a drainage channel. The slope protection frame serves as the main structure, dividing the entire slope into multiple small units, effectively distributing and transferring the slope load. The anchor bolts are deeply inserted into stable strata and tightly connected to the slope protection frame and fixing frame, like nails firmly anchoring the entire protection structure to the slope, resisting deep slope sliding and shallow collapse. The slope protection mesh covers the frame, directly constraining the surface soil of the slope and preventing rainwater erosion and particle loss. Attached Figure Description

[0026] This utility model provides an ecological protection structure for roadbed slopes that is seepage-proof and crack-resistant.

[0027] Please see Figure 1 and Figure 5The system includes a protective box 1, with a slope protection frame 3 fixedly connected to the lower end of the protective box 1. A fixing frame 6 is fixedly connected to one side of the slope protection frame 3. A fixing shaft 7 is fixedly connected to the inner wall of the fixing frame 6. An installation frame 8 is fixedly connected to the end of the fixing shaft 7 away from the fixing frame 6. A slope protection mesh 9 is fixedly connected to the inner side of the installation frame 8. The fixing shaft 7 is installed on the fixing frame 6. The installation frame 8 can be installed between the two fixing frames 6 through the fixing shaft 7, which serves a fixing function. The slope protection mesh 9 can be installed on the installation frame 8 through fixing bolts. The slope protection mesh 9 can protect the surface of the slope and prevent the slope from collapsing, thus serving a protective function. The holes set in the slope protection mesh 9 can facilitate the growth of plants, and the root system of the plants can strengthen the fixation of the slope.

[0028] Please see Figure 3 The upper end of the fixing frame 6 is fixedly connected to the slope protection top plate 5, and the lower side of the fixing frame 6 is fixedly connected to the anchor rod 10. Both the slope protection top plate 5 and the anchor rod 10 are installed on the fixing frame 6 to fix it. The slope protection top plate 5 can protect the top of the slope and prevent water accumulation at the top of the slope. The anchor rod 10 is inserted into the inside of the slope and can pull the fixing frame 6 to prevent it from loosening. The fixing frame 6 has a drainage groove 11 on its inner side. The fixing frame 6 is installed on the slope protection frame 3. The bottom of the fixing frame 6 is fixed by the slope protection frame 3 to prevent the fixing frame 6 from slipping. The fixing frame 6 is provided with a drainage groove 11 to drain water.

[0029] Please see Figure 2 A water channel 4 is provided on one side of the slope protection frame 3. The protective box 1 is installed on the slope protection frame 3 for fixation. The water channel 4 on the slope protection frame 3 allows water to flow in and prevents rainwater from seeping into the slope from the bottom, causing the bottom to loosen and collapse. A protective mechanism 2 is provided inside the protective box 1. The protective mechanism 2 includes a slide rail 201 fixedly connected to the inside of the protective box 1. The other side of the slide rail 201 is fixedly connected to the fixed end of the first buffer 207. One side of the protective plate 208 is slidably connected to the inside of the protective box 1. The first buffer 207 is installed on the slide rail 201. The first buffer 207 supports the protective plate 208, thus providing a buffering effect. The protective plate 208 can slide inside the protective box 1. The protective plate 208 can block falling stones and provide protection. A second buffer 209 is fixedly connected to one side of the slide rail 201. The telescopic end of the second buffer 209 is fixedly connected to one side of the protective plate 208. The second buffer 209 is installed at both ends of the slide rail 201. The second buffers 209 on both sides can fix the two sides of the protective plate 208, preventing the protective plate 208 from tilting and providing a guiding effect.

[0030] Please see Figure 4 A fixing block 202 is fixedly connected to the outer surface of the slide rail 201. A slide rod 203 is fixedly connected to one side of the fixing block 202. A slider 205 is slidably connected to the outer surface of the slide rod 203. A spring 204 is fixedly connected to one side of the slider 205. The end of the spring 204 away from the slider 205 is fixedly connected to one side of the fixing block 202. A connecting rod 206 is hinged to the other side of the slider 205. A first buffer 207 is hinged to the end of the connecting rod 206 away from the slider 205. A protective plate 208 is fixedly connected to the telescopic end of the first buffer 207. When a rock falls onto the protective plate 208, the protective plate 208 is impacted and moves back. The first buffer 207 and the second buffer 209 set inside the protective plate 208 can buffer the downward movement of the protective plate 208, preventing the falling rocks from damaging passing vehicles.

[0031] Working principle: When a rock falls from a height and impacts the protective plate 208, the impact force pushes the protective plate 208 inward. The movement of the protective plate 208 triggers a two-stage buffer mechanism to absorb and dissipate the impact energy. The retraction of the protective plate 208 compresses the first buffer 207 at its back and the second buffers 209 on both sides. These buffers are usually filled with hydraulic oil or gas, which converts a large amount of impact kinetic energy into heat energy through damping. At the same time, the contraction of the first buffer 207 pushes the slider 205 along the slide bar 203 through the connecting rod 206 hinged to it. The movement of the slider 205 compresses or stretches the spring 204, converting the remaining impact force into spring energy. The elastic potential energy of spring 204, through the linkage buffer of these two stages, gradually absorbs and dissipates the strong impact force of falling rocks, greatly reducing the peak load borne by the protective plate 208, thereby effectively preventing it from cracking, breaking or causing permanent deformation, and ensuring the long-term safety and stability of the slope protection structure. At the same time, the slope protection frame 3, the fixing frame 6 and the deeply buried anchor rods 10 at the bottom of the entire structure work together to firmly anchor the structure to the slope and resist deep sliding. The slope protection mesh plate 9 on the surface restrains the surface soil and prevents rainwater erosion. The water guide channel 4 and the drainage channel 11 can drain rainwater in time and prevent water from seeping into the interior of the slope, causing leakage or landslides, thus achieving a combination of ecological protection and structural safety.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
