Technical Field
[0001] This utility model relates to the field of highway subgrade slope protection technology, and in particular to a highway subgrade slope protection structure. Background Technology
[0002] Highway subgrade slope protection structures are engineering structures designed to prevent subgrade slopes from being damaged by natural factors (such as rainwater erosion, weathering, earthquakes, etc.) or vehicle loads, thereby ensuring the stability and safety of the subgrade.
[0003] Traditional highway subgrade slope protection structures are usually designed with a drainage channel on top for drainage of the highway surface. However, the existing drainage channels on top of highway subgrade slope protection structures often lack a filtration structure, which leads to the accumulation of materials such as stones and garbage in the drainage channels, making them difficult to clean.
[0004] Therefore, those skilled in the art have provided a highway subgrade slope protection structure to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a highway subgrade slope protection structure. This structure features a filter plate slidably installed inside a water collection trough. By rotating a threaded rod, the filter plate, connected to the bottom of the threaded rod, can move up and down, facilitating the cleaning of debris inside the water collection trough by highway sanitation workers. This structure solves the problem that existing highway subgrade slope protection structures often lack a filter structure at the top of the drainage trough, leading to the accumulation of stones and debris that are difficult to clean.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A roadbed slope protection structure includes a base and a concrete frame. The concrete frame is poured on top of the base. A water collection trough is designed at the top of the concrete frame. A fixing frame is installed in the middle of the water collection trough at the top of the concrete frame. A threaded rod is threadedly installed in the middle of the fixing frame. A filter plate is rotatably installed at the bottom end of the threaded rod. The top dimension of the filter plate is the same as the internal dimension of the water collection trough.
[0008] The above technical solution involves a filter plate that is slidably installed inside the water collection trough. By rotating the threaded rod, the filter plate connected to the bottom of the threaded rod can be controlled to move up and down, making it convenient for highway sanitation workers to clean up the garbage inside the water collection trough. The above structure solves the problem that the drainage troughs at the top of existing highway subgrade slope protection structures usually lack a filter structure, which leads to the accumulation of stones and garbage in the drainage trough, making it difficult to clean.

Each U-shaped drainage block has multiple V-shaped blocking blocks on its inner side, and a through hole is opened at the bottom center of each of the multiple V-shaped blocking blocks.
[0010] The above technical solution involves designing side blocks at both ends of the concrete frame and two sets of U-shaped drainage blocks on the inclined surface of the concrete frame. The combination of side blocks and U-shaped drainage blocks facilitates the diversion of rainwater discharge. Multiple V-shaped blocking blocks are designed on the inner side of each U-shaped drainage block to block and deflect objects falling from the roadside, thereby reducing the impact of the rolling objects.
[0011] Furthermore, the water collection tank has a limiting groove at both ends, the filter plate has a limiting block integrally provided at both ends, the concrete frame has a limiting frame at both ends, and a sliding rod is installed at the bottom of the two limiting grooves. One end of the sliding rod on the same side is fixedly connected to the limiting frame, and the limiting block on the same side is slidably connected to the sliding rod.
[0012] Through the above technical solution, the design of the limiting block and the limiting groove allows the filter plate to be slidably installed inside the water collection tank. The design of the sliding rod can limit the position of the filter screen, making it convenient for the filter plate to be aligned with the water collection tank.
[0013] Furthermore, a drainage ditch is designed at one end of the concrete frame, and a drainage channel is opened in the middle of the concrete frame. The two ends of the drainage channel are connected to a water collection tank and a drainage ditch, respectively.
[0014] The above technical solution involves designing a drainage ditch at one end of the concrete frame to facilitate the centralized discharge of rainwater, and a drainage channel in the middle of the concrete frame. The two ends of the drainage channel are connected to the water collection tank and the drainage ditch respectively, so as to facilitate the flow of water from the water collection tank into the drainage ditch.
[0015] Furthermore, a plurality of concrete anchor rods are integrally provided at the bottom end of the concrete frame, and all of the concrete anchor rods are inserted into the base.
[0016] Through the above technical solution, multiple concrete anchor rods are integrally set at the bottom end of the concrete frame, and all the concrete anchor rods are inserted into the base to facilitate fixing the concrete frame to the base surface.
[0017] Furthermore, a turntable is integrally provided at the top end of the threaded rod;
[0018] The above technical solution integrates a turntable at the top of the threaded rod to facilitate rotation of the threaded rod.
[0019] Furthermore, a pair of fixing bolts are installed at both ends of the connection between the fixing frame and the concrete frame;
[0020] With the above technical solution, a pair of fixing bolts are installed at both ends of the connection between the fixing frame and the concrete frame, so as to facilitate the installation and fixing of the fixing frame.
[0021] This utility model has the following beneficial effects:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0032] Reference Figure 1-5 This utility model provides an embodiment of a highway subgrade slope protection structure, comprising a base 1 and a concrete frame 2. The concrete frame 2 is cast on top of the base 1. A water collection trough 4 is designed at the top of the concrete frame 2. A fixing frame 5 is installed in the middle of the water collection trough 4. A threaded rod 6 is threadedly installed in the middle of the fixing frame 5. A filter plate 7 is rotatably installed at the bottom end of the threaded rod 6. The top dimension of the filter plate 7 is the same as the internal dimension of the water collection trough 4. By sliding the filter plate 7 inside the water collection trough 4, the filter plate 7 connected to the bottom end of the threaded rod 6 can be controlled to move up and down by rotating the threaded rod 6, thereby facilitating the cleaning of garbage inside the water collection trough 4 by highway sanitation workers. The above structure solves the defect that the drainage trough at the top of the existing highway subgrade slope protection structure usually lacks a filtration structure, which leads to the deposition of stones and garbage in the drainage trough, making it difficult to clean.
[0033] Both ends of the concrete frame 2 are equipped with side blocks 14, and two sets of U-shaped drainage blocks 17 are designed on the inclined surface of the concrete frame 2. Each U-shaped drainage block 17 has multiple V-shaped blocking blocks 18 on its inner side, and each V-shaped blocking block 18 has a through hole at its bottom center. By designing side blocks 14 at both ends of the concrete frame 2 and two sets of U-shaped drainage blocks 17 on its inclined surface, the combination of side blocks 14 and U-shaped drainage blocks 17 facilitates the diversion of rainwater discharge. The multiple V-shaped blocking blocks 18 on the inner side of each U-shaped drainage block 17 further facilitate the diversion of rainwater discharge. To mitigate the impact of objects falling from the roadside, the water collection trough 4 has limit grooves 11 at both ends, and the filter plate 7 has limit blocks 10 integrally installed at both ends. The top of the concrete frame 2 has limit frames 12 at both ends. Sliding rods 13 are installed at the bottom of both limit grooves 11. One end of the sliding rod 13 on the same side is fixedly connected to the limit frame 12, and the limit block 10 on the same side is slidably connected to the sliding rod 13. The design of the limit blocks 10 and limit grooves 11 allows the filter plate 7 to slide inside the water collection trough 4. The sliding rod 13 can control the position of the filter screen. The design restricts the flow of water to facilitate alignment between the filter plate 7 and the water collection tank 4. A drainage ditch 3 is designed at one end of the concrete frame 2, and a drainage channel 15 is provided in the middle of the concrete frame 2. Both ends of the drainage channel 15 are connected to the water collection tank 4 and the drainage ditch 3, respectively. The drainage ditch 3 at one end of the concrete frame 2 facilitates the centralized discharge of rainwater. The drainage channel 15 in the middle of the concrete frame 2 connects both ends to the water collection tank 4 and the drainage ditch 3, allowing water from the water collection tank 4 to flow into the drainage ditch 3. Multiple concrete anchor rods 1 are integrally installed at the bottom of the concrete frame 2. 6. Multiple concrete anchor rods 16 are inserted into the base 1. Multiple concrete anchor rods 16 are integrally set at the bottom end of the concrete frame 2, and multiple concrete anchor rods 16 are inserted into the base 1 to facilitate fixing the concrete frame 2 to the surface of the base 1. A turntable 8 is integrally set at the top end of the threaded rod 6 to facilitate rotating the threaded rod 6. A pair of fixing bolts 9 are installed at both ends of the connection between the fixing frame 5 and the concrete frame 2 to facilitate the installation and fixing of the fixing frame 5.
[0034] Working principle: A filter plate 7 is slidably installed inside the water collection trough 4. By rotating the threaded rod 6, the filter plate 7 connected to the bottom of the threaded rod 6 can be moved up and down, making it convenient for road sanitation workers to clean the garbage inside the water collection trough 4. The above structure solves the problem that the drainage troughs at the top of the existing roadbed slope protection structure usually lack a filtration structure, which leads to the accumulation of stones and garbage in the drainage trough and makes it difficult to clean. Side blocks 14 are designed at both ends of the concrete frame 2, and two sets of U-shaped drainage blocks 17 are designed on the inclined surface of the concrete frame 2. The combination of side blocks 14 and U-shaped drainage blocks 17 facilitates the diversion of rainwater discharge. Multiple V-shaped blocking blocks 18 are designed on the inner side of each U-shaped drainage block 17 to block and deflect objects falling from the roadside, thereby reducing the impact of rolling objects.
