Description
Technical Field
[0001] This utility model relates to the field of prefabricated retaining wall technology, specifically a prefabricated impact-resistant retaining wall structure. Background Technology
[0002] Prefabricated retaining walls are structural facilities used to prevent soil sliding and collapse, and to maintain soil stability. They are commonly found on slopes along roadsides, around foundation pits in construction projects, and along the banks of rivers or reservoirs. They can balance the lateral pressure of the soil through their own supporting force, preventing landslides and collapses caused by soil instability. At the same time, they can also protect surrounding roads, buildings, underground pipelines and other facilities from the impact of soil movement, help maintain the flatness and order of the site topography, and meet the safety requirements of engineering construction, traffic flow and water conservancy protection.
[0003] Existing prefabricated retaining walls have significant design shortcomings, generally lacking impact-resistant buffer structures. When faced with accidental vehicle collisions, sudden soil slippage and compression on slopes, or the impact of rainwater carrying debris after heavy rain, the impact force is directly and completely transmitted to the wall structure, easily leading to partial collapse and component detachment. If located next to roads, this could block traffic and damage passing vehicles; if near foundation pits or rivers, it could cause soil instability and river backflow, threatening the safety of surrounding construction sites and the lives of residents. Furthermore, due to the lack of buffer structures, once the wall is damaged, extensive repairs are required, increasing maintenance costs and affecting the long-term usability of the site. Therefore, we propose a prefabricated impact-resistant retaining wall structure. Utility Model Content
[0004] The purpose of this utility model is to provide a prefabricated impact-resistant retaining wall structure to address the significant shortcomings in the design of existing prefabricated retaining walls mentioned in the background art. These walls generally lack a buffer structure to withstand impacts. When faced with accidental vehicle collisions, sudden soil slippage and compression on slopes, or the impact of rainwater carrying debris, the impact force is directly and completely transmitted to the wall body, easily leading to partial wall collapse and component detachment. If located next to a road, this could block traffic and damage passing vehicles. If located near a foundation pit or river, it could cause soil instability and river backflow, threatening the safety of surrounding construction and the lives of residents. Furthermore, due to the lack of a buffer structure, once the wall is damaged, extensive repairs are required, increasing maintenance costs and affecting the long-term normal use of the site.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated impact-resistant retaining wall structure, including a base plate, a wall panel on one side of the base plate, a vertical plate fixedly connected to the top of the base plate near one side, connecting plates fixedly connected to the top and bottom of one side of the vertical plate, a sliding rod fixedly installed between the two connecting plates near one side, two sliding sleeves slidably connected to the center of the surface of the sliding rod, connecting blocks fixedly connected to the front and rear ends of the top and bottom positions of the vertical plate and the wall panel on the opposite side, a buffer spring sleeved at the center of the surface of the sliding rod, movable rods hinged to the front and rear ends of the two sliding sleeves, grooves formed at the front and rear ends of the center of one side of the vertical plate, connecting columns fixedly connected to one side of each of the four grooves on one side of the wall panel, a damping rod fixedly installed in one side of each groove, limit guide grooves formed at the center of the top and bottom of each groove, and limit guide blocks fixedly connected to the top and bottom of each connecting column.
[0006] Compared with the prior art, the beneficial effects of this utility model are: This prefabricated impact-resistant retaining wall structure, through the design of vertical plates, connecting plates, sliding rods, sliding sleeves, connecting blocks, buffer springs, movable rods, damping rods, connecting columns, limiting guide grooves, and limiting guide blocks, ensures that when the wall panel is subjected to external forces such as vehicle impacts, soil compression, or water flow carrying debris, the impact force is simultaneously transmitted to two sets of core buffer structures. The connecting blocks on the side of the wall panel drive the hinged movable rods to deflect, and the movable rods further push the sliding sleeves to slide directionally along the sliding rods. The buffer springs undergo elastic deformation with the movement of the sliding sleeves, quickly absorbing and dispersing part of the impact energy, initially weakening the direct effect of external forces on the main body of the wall. At the same time, the connecting columns move synchronously into the grooves, pushing the damping rods within the grooves to extend and retract. The damping rods, relying on their own damping energy dissipation characteristics, further consume the remaining energy. Impact energy is effectively reduced, preventing the impact force from being continuously transmitted to the core load-bearing structures such as the base plate and vertical plates. At the same time, the limiting guide blocks on the connecting columns slide stably along the limiting guide grooves in the grooves, effectively limiting the movement trajectory of the connecting columns and damping rods. This prevents problems such as component misalignment and displacement during the buffering process, ensuring the stable operation of the buffer structure at all times. This not only makes up for the shortcomings of traditional prefabricated retaining walls in lacking effective buffering structures, but also dissipates impact energy layer by layer through the synergistic effect of multiple structures. It significantly reduces the risk of wall panel cracking, loosening of splices, or even local collapse caused by impact force, significantly improving the impact resistance and structural stability of the retaining wall and extending its service life. It is especially suitable for impact-prone scenarios such as roadsides and foundation pits, providing more reliable protection for surrounding traffic, construction safety, and residents' lives.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0010] Please see Figure 1-4 This utility model provides a technical solution: a prefabricated impact-resistant retaining wall structure, including a base plate 1, a wall panel 2 on one side of the base plate 1, a vertical plate 3 fixedly connected to the top of the base plate 1 near one side, connecting plates 4 fixedly connected to the top and bottom of the vertical plate 3, a sliding rod 5 fixedly installed between the two connecting plates 4 near one side, two sliding sleeves 6 slidably connected to the center of the surface of the sliding rod 5, and connecting blocks fixedly connected to the front and rear ends of the top and bottom positions of the vertical plate 3 on the opposite side of the wall panel 2. 7. A buffer spring 8 is sleeved at the center of the surface of the slide rod 5. Movable rods 9 are hinged to both sides of the front and rear ends of the two sliding sleeve plates 6. Grooves 10 are provided at the front and rear ends of the center of one side of the vertical plate 3. Connecting columns 12 are fixedly connected to one side of the wall plate 2 corresponding to the four grooves 10 respectively. A damping rod 11 is fixedly installed on one side of the groove 10. Limiting guide grooves 13 are provided at the center of the top and bottom of the groove 10. Limiting guide blocks 14 are fixedly connected to one side of the top and bottom of the connecting column 12.
[0011] The top and bottom of the buffer spring 8 are fixedly connected to the opposite sides of the two sliding sleeve plates 6. When the sliding sleeve plate 6 is pushed by an external force to slide along the slide rod 5, the buffer spring 8 can generate elastic deformation with the relative movement of the sliding sleeve plate 6. Through the extension and contraction process, it absorbs and stores part of the impact energy. At the same time, it uses the spring's reset characteristic to drive the sliding sleeve plate 6 back to its original position, forming the first elastic buffer defense line and weakening the direct impact of the impact force on the wall.
[0012] One end of each of the eight movable rods 9 is hinged to the front and rear surfaces of the eight connecting blocks 7, respectively. The impact force on the wall panel 2 is transmitted to the sliding sleeve 6 through the connecting blocks 7. At the same time, the rotatable characteristics of the hinge structure are used to convert the lateral impact of the wall panel 2 into the longitudinal sliding of the sliding sleeve 6 along the sliding rod 5, thereby realizing the direction conversion and dispersion of the impact force and ensuring that the buffer spring 8 can effectively participate in energy dissipation.
[0013] One end of each of the four connecting columns 12 passes through the interior of the four grooves 10 and is fixedly connected to one side of the damping rod 11, so that the impact force borne by the wall panel 2 is directly transmitted to the damping rod 11. When the wall panel 2 is displaced by impact, the connecting column 12 can push the damping rod 11 to extend and retract, and the damping energy dissipation characteristics of the damping rod 11 are used to consume the impact energy, forming a second buffer line, further reducing the impact of the impact force on the vertical plate 3 and the bottom plate 1.
[0014] The top and bottom of the two limiting guide blocks 14, which are set at the top and bottom respectively, extend into the interior of the two limiting guide grooves 13 and slide to connect with the inner wall of the limiting guide grooves 13. Through the sliding cooperation between the limiting guide blocks 14 and the limiting guide grooves 13, the movement trajectory of the connecting column 12 and the damping rod 11 is strictly limited, preventing misalignment or jamming due to force deviation during the buffering process, ensuring that the damping rod 11 can stably play its energy dissipation role, and ensuring the orderly operation of the buffer structure.
[0015] The front and rear ends of the top of one side of the vertical plate 3 are fixedly connected to the support diagonal rods 15. The lower ends of the two support diagonal rods 15 are fixedly connected to the top of the base plate 1. The two support diagonal rods 15 and the vertical plate 3 are fixedly connected to the support horizontal rods 16. Through the triangular support structure of the support diagonal rods 15 and the support horizontal rods 16, the connection rigidity between the vertical plate 3 and the base plate 1 is enhanced, the deformation resistance of the vertical plate 3 is improved, and a stable installation foundation is provided for components such as the sliding rod 5 and the damping rod 11 during the buffering process. This prevents the vertical plate 3 from tilting or breaking due to impact force and ensures the stability of the overall structure.
[0016] Working principle: When the wall panel 2 is impacted by an external force, the impact force first acts on the wall panel 2 body, and then simultaneously transfers energy to the two sets of core buffer structures. On the one hand, the wall panel 2 transfers part of the impact force to the connecting block 7 between it and the vertical plate 3. Since one end of each of the eight movable rods 9 is hinged to one of the eight connecting blocks 7, the impact force will drive the movable rods 9 to rotate around the connecting block 7, thereby pushing the sliding sleeve 6, which is hinged to the other end of the movable rod 9, to slide in opposite directions along the slide rod 5 fixed on the connecting plate 4. At this time, the buffer spring 8, which is sleeved on the surface of the slide rod 5 and fixed at both ends to the sliding sleeve 6, undergoes elastic deformation with the displacement of the sliding sleeve 6. Through the extension and contraction process, it absorbs and temporarily stores part of the impact energy. At the same time, the spring's reset characteristic can drive the sliding sleeve 6 and the movable rod 9 to return to their original positions, completing the first elastic buffer and initially weakening the intensity of the external force. On the other hand, the wall panel 2 simultaneously drives the connecting column 12 on its side to move into the groove 10 of the vertical plate 3. Since one end of the connecting column 12 is fixed to the damping rod 11 in the groove 10, the damping rod 11 will be pushed to extend and retract during the displacement. The damping rod 11, with its own damping energy dissipation characteristics, converts the remaining impact energy into heat energy and other forms of energy, forming a second layer of buffer, further reducing the impact force on the vertical plate 3 and the bottom plate 1. During this process, the limiting guide blocks 14 at the top and bottom of the connecting column 12 slide along the limiting guide groove 13 in the groove 10, strictly limiting the movement trajectory of the connecting column 12 and the damping rod 11, avoiding jamming or misalignment due to force deviation, ensuring that the second layer of buffer is stable and effective, and realizing the impact protection function of the retaining wall.
[0017] In summary, this prefabricated impact-resistant retaining wall structure, through the design of vertical plate 3, connecting plate 4, sliding rod 5, sliding sleeve plate 6, connecting block 7, buffer spring 8, movable rod 9, damping rod 11, connecting column 12, limiting guide groove 13, and limiting guide block 14, ensures that when the wall panel 2 is subjected to external forces such as vehicle impact, soil compression, or water flow carrying debris, the impact force is simultaneously transmitted to the two sets of core buffer structures. The connecting block 7 on the side of the wall panel 2 will drive the hinged movable rod 9 to deflect, and the movable rod 9 will further push the sliding sleeve plate 6 to slide directionally along the sliding rod 5. The buffer spring 8 will undergo elastic deformation with the movement of the sliding sleeve plate 6, quickly absorbing and dispersing part of the impact energy, initially weakening the direct effect of external forces on the main body of the wall. At the same time, the connecting column 12 will move synchronously into the groove 10, pushing the damping rod 11 in the groove 10 to extend and retract. The damping rod 11, through its own damping... The energy-consuming characteristics further dissipate the remaining impact energy, preventing the impact force from being continuously transmitted to the core load-bearing structures such as the base plate 1 and the vertical plate 3. At the same time, the limiting guide block 14 on the connecting column 12 will slide stably along the limiting guide groove 13 in the groove 10, effectively limiting the movement trajectory of the connecting column 12 and the damping rod 11, preventing problems such as component misalignment and displacement during the buffering process, and ensuring that the buffer structure always operates stably. This not only makes up for the shortcomings of traditional prefabricated retaining walls that lack effective buffering structures, but also dissipates the impact energy layer by layer through the synergistic effect of multiple structures, greatly reducing the risk of wall panel 2 cracking, splicing loosening, or even local collapse caused by impact force. It significantly improves the impact resistance and structural stability of the retaining wall, extends its service life, and is especially suitable for impact-prone scenarios such as roadsides and foundation pits, providing more reliable protection for surrounding traffic, construction safety, and residents' lives.
