Description

Technical Field

[0001] This utility model relates to the field of retaining wall structure technology, and in particular to a retaining wall structure for railway subgrade cuttings. Background Technology

[0002] Railway subgrade retaining walls, as important supporting structures in railway engineering, play a crucial role in maintaining the stability of the cutting slope. Railway subgrade retaining walls can be constructed using gravity, cantilever, or buttress structures. Gravity retaining walls rely on their own weight to resist earth pressure; they are simple in structure, easy to construct, and suitable for sections with low wall height and good foundations. Cantilever retaining walls consist of a vertical wall, a toe slab, and a heel slab, utilizing the weight of the backfill on the heel slab and their own structural characteristics to maintain stability. Compared to gravity retaining walls, they save materials and are suitable for sections with moderate wall height. Buttress retaining walls, based on the cantilever structure, add buttresses, enhancing the wall's bending resistance and overall stability, and are suitable for higher cutting retaining walls.

[0003] A search revealed Chinese Patent Publication No. CN216515665U, which discloses a reinforcement structure for expansive soil road cut slopes, relating to the field of slope reinforcement technology. This structure addresses the problem of expansive soil slopes being unstable and prone to landslides. The structure includes a slope body, inclined pipes fixedly installed on the slope body, and water guide seats fixedly installed at the bottom of the slope body. Waterproof geotextile is laid between adjacent inclined pipes. A drainage blind pipe is fixedly connected to the side of the inclined pipe closest to the slope. The bottom of the inclined pipe communicates with the interior of the water guide seat, and adjacent water guide seats are fixedly connected by a connecting pipe. This application utilizes waterproof geotextile to effectively reduce the infiltration of rainwater into the interior of the slope. Furthermore, by using drainage blind pipes to drain water from inside the slope into inclined pipes, which are then guided away by water guide seats, the accumulation of rainwater within the slope is effectively reduced. Additionally, the precast retaining wall is designed to prevent landslides. However, in actual use, the inability to promptly drain rainwater from the slope leads to severe soil erosion, causing voids to appear on the back of the retaining wall. Under uneven stress, this results in the retaining wall collapsing. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a retaining wall structure for railway subgrade cuttings, aiming to improve the problem in the existing technology where rainwater inside the hillside cannot be drained in time, resulting in severe soil erosion, causing the back of the retaining wall to become hollow, and leading to the collapse of the retaining wall under uneven stress.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a retaining wall structure for railway subgrade cutting, comprising an L-shaped baffle, wherein drainage mechanisms are provided on the upper and lower sides of the rear rear part of the inner wall of the L-shaped baffle, an inclined baffle is fixedly connected to the rear top of the L-shaped baffle, a plurality of limiting components are provided on the inner wall of the inclined baffle, buffer components are arranged sequentially on adjacent sides of two L-shaped baffles, a water diversion component is provided on the top of the inclined baffle, and a ladder mechanism is provided on the adjacent front side of two L-shaped baffles;

[0006] The drainage mechanism includes multiple hollow processing blocks. The front sides of the multiple hollow processing blocks are respectively fixedly connected to the upper and lower rear sides of the inner wall of the L-shaped baffle. A partition plate is fixedly connected to the middle of the inner wall of the hollow processing block. Multiple filter holes are opened at the top of the partition plate. Multiple drain outlets are opened on the front side of the L-shaped baffle. The rear side of the drain outlet is connected to the front side of the hollow processing block.

[0007] Through the above technical solution: the L-shaped baffle serves as the main structure of the retaining wall, directly bearing the lateral pressure from the cut soil. The inclined baffle is set at the top of the L-shaped baffle, increasing the obstruction of the cut soil above while reducing material usage. When there is a large amount of water in the cut soil, the hollow block is divided into two parts by the partition plate. Sand and gravel are placed above the partition plate, and stones are placed below the partition plate. Water will be filtered through the sand and gravel above the partition plate, and impurities such as mud and sand will be filtered out by the filter holes at the top. The water will then flow into the stones placed below the partition plate and be discharged through the drainage outlet. This avoids excessive water pressure caused by water accumulation behind the wall and prevents the soil from softening and becoming unstable due to long-term immersion in water.

[0008] As a further description of the above technical solution:

[0009] The ladder mechanism includes multiple trapezoidal grooves, the rear sides of which are respectively opened on the adjacent front side of the L-shaped baffle. A limiting tube is fixedly connected to the front of the L-shaped baffle, a reinforcing strip is fixedly connected to the top of the L-shaped baffle, and multiple connecting columns are fixedly connected to the rear of the inner wall of the L-shaped baffle. A limiting plate is fixedly connected to the rear of the connecting columns.

[0010] The above technical solution utilizes trapezoidal grooves to facilitate climbing by construction workers, which is beneficial for the inspection and maintenance of the retaining wall. The limiting tubes facilitate climbing by construction workers and provide good protection. The reinforcing strips enhance the structural strength of the top of the L-shaped baffle and improve the overall stability. The connecting columns and limiting plates can help fix the L-shaped baffle and enhance the overall structure. At the same time, the limiting plates can also block the slight displacement of the soil behind the wall to a certain extent.

[0011] As a further description of the above technical solution:

[0012] The limiting component includes multiple reinforcing columns, the top ends of the outer walls of the multiple reinforcing columns are fixedly connected at equal intervals to the inner wall of the inclined baffle, and the bottom ends of the reinforcing columns are fixedly connected to limiting blocks.

[0013] The above technical solutions can limit the displacement of the soil behind the wall, enhance the connection between the soil and the retaining wall, improve soil stability, and prevent soil slippage.

[0014] As a further description of the above technical solution:

[0015] The buffer assembly includes a buffer plate, the outer walls of which are fixedly connected to adjacent sides of the two L-shaped baffles on their left and right sides respectively, and the outer walls of the buffer plate are provided with multiple notches.

[0016] Through the above technical solution, the notches on the buffer plate can absorb energy through their own deformation when subjected to external forces, thereby mitigating the impact of external forces on the retaining wall and protecting the retaining wall structure.

[0017] As a further description of the above technical solution:

[0018] The water intake assembly includes multiple drainage channels, the outer walls of which are formed on the top of the inclined baffle, and multiple water intake channels are formed at the front of the L-shaped baffle.

[0019] The above technical solution involves a drainage ditch that collects rainwater above the inclined baffle and then diverts the water to an area away from the retaining wall via a water diversion channel, thereby further reducing the adverse effects of water on the retaining wall.

[0020] As a further description of the above technical solution:

[0021] An L-shaped strip is fixedly connected to the bottom front side of the L-shaped baffle, and a U-shaped block is fixedly connected to the front side of the L-shaped strip.

[0022] The above technical solution involves a fixed connection between the L-shaped strip and the bottom front of the L-shaped baffle. By increasing the structural thickness and support area at the bottom, the bending and shear resistance of the bottom of the L-shaped baffle is effectively improved. The U-shaped block can guide the direction of water flow, preventing water from directly eroding the connection between the L-shaped strip and the L-shaped baffle, thus reducing the risk of structural damage caused by water erosion.

[0023] As a further description of the above technical solution:

[0024] The top edge of the outer wall of the U-shaped block and the top edge of the outer wall of the L-shaped strip are on the same horizontal plane, and the size of the hollow block being processed is the same as the size of the inner wall of the L-shaped baffle.

[0025] The above technical solution avoids local stress concentration caused by height differences by using the same horizontal plane. The size of the hollow block is consistent with the inner wall size of the L-shaped baffle, which can filter and discharge the water flowing into the hollow block, thus giving full play to the function of the drainage mechanism.

[0026] As a further description of the above technical solution:

[0027] The outer wall of the trapezoidal groove is equidistantly formed on the front side of the L-shaped baffle, and the front ends of the plurality of connecting posts are equidistantly fixed to the front side of the inner wall of the L-shaped baffle.

[0028] The above technical solution ensures that the L-shaped baffle is evenly stressed on the front side, preventing structural damage caused by excessive local stress. The front ends of multiple connecting columns are fixedly connected to the inner wall of the L-shaped baffle at equal intervals, ensuring that the structure above the connecting columns exerts a uniform force on the L-shaped baffle.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, an L-shaped baffle is used as the main structure to withstand the lateral pressure of the cut soil. The inclined baffle at the top increases the blocking effect and reduces the use of materials. When the cut soil has a high water content, the hollow block is divided into two parts by a partition plate. Sand and gravel are placed on top for filtration. Impurities are removed through the filter holes, and water is discharged through the drain outlet to prevent water accumulation behind the wall and soil softening and instability.

[0031] 2. In this utility model, the trapezoidal groove facilitates construction workers' climbing and inspection of the retaining wall, while the limiting tube provides protection for climbing. The reinforcing strip enhances the structural strength and stability of the L-shaped baffle, and the connecting column and limiting plate fix the L-shaped baffle, strengthening the overall structure and thus limiting minor displacement of the soil behind the wall. This improves its connection with the soil pile. Attached Figure Description

The water diversion component 9 can drain water to an area away from the retaining wall, further reducing the adverse effects of water on the retaining wall. A ladder mechanism 3 is provided on the adjacent front side of the two L-shaped baffles 1. The drainage mechanism 2 includes multiple hollow processing blocks 201. The front sides of the multiple hollow processing blocks 201 are respectively fixedly connected to the upper and lower rear sides of the inner wall of the L-shaped baffle 1.

The rear side of the drain outlets 204 is connected to the front side of the hollow block 201. Since the hollow block 201 is divided into two parts by the partition plate 202, sand and gravel are placed above the partition plate 202, and stones are placed below the partition plate 202. Water will pass through the sand and gravel above the partition plate 202 for filtration, and the filter holes 203 at the top will filter out impurities such as mud and sand. The water will then flow into the stones placed below the partition plate 202 and drain through the drain outlets 204. 04 Discharge; Limiting component 5 includes multiple reinforcing columns 501, the top of the outer wall of the multiple reinforcing columns 501 is fixedly connected at equal intervals to the inner wall of the inclined baffle 4, and the bottom of the reinforcing column 501 is fixedly connected to a limiting block 502; Buffer component 8 includes a buffer plate 801, the left and right sides of the outer wall of the buffer plate 801 are fixedly connected to the adjacent side of the two L-shaped baffles 1 respectively, and the outer wall of the buffer plate 801 is provided with multiple notches 802; Water guiding component 9 includes multiple drainage channels 901, the outer walls of the multiple drainage channels 901 are all opened on the top of the inclined baffle 4, and the front part of the L-shaped baffle 1 is provided with multiple water guiding channels 902;

[0041] Specifically, the L-shaped baffle 1, as the main structure of the retaining wall, directly bears the lateral pressure from the cut soil. The inclined baffle 4 is installed at the top of the L-shaped baffle 1, increasing the obstruction of the cut soil above while reducing material usage. Furthermore, when there is a large amount of water in the cut soil, the hollow block 201 is divided into two parts by the partition plate 202. Sand and gravel are placed above the partition plate 202, and stones are placed below it. Water will be filtered through the sand and gravel above the partition plate 202, and impurities such as mud and sand will be filtered out by the filter holes 203 at the top. The water then flows into the stones placed below the partition plate 202 and is discharged through the drainage outlet 204. The retaining components 5 and 8 are designed to prevent excessive water pressure caused by water accumulation behind the wall, thus preventing the soil from softening and becoming unstable due to long-term immersion in water. The reinforcing column 501 and limiting block 502 in the limiting component 5 can limit the displacement of the soil behind the wall, enhance the connection between the soil and the retaining wall, improve the stability of the soil, and prevent the soil from sliding down. The notch 802 on the buffer plate 801 in the buffer component 8 can absorb energy through its own deformation when subjected to external force, alleviate the impact of external force on the retaining wall, and protect the retaining wall structure. At the same time, the drainage channel 901 in the water diversion component 9 collects rainwater above the inclined baffle 4 and drains the water to an area away from the retaining wall through the water diversion channel 902, further reducing the adverse effects of water on the retaining wall.

[0042] Reference Figure 1 , Figure 2 and Figure 3 The ladder mechanism 3 includes multiple trapezoidal grooves 301. The rear sides of the multiple trapezoidal grooves 301 are respectively opened on the adjacent front side of the L-shaped baffle 1. The trapezoidal grooves 301 facilitate the climbing of construction personnel and facilitate the inspection of the retaining wall. The front part of the L-shaped baffle 1 is fixedly connected to a limiting tube 302, which facilitates the climbing of construction personnel and provides good protection. The top of the L-shaped baffle 1 is fixedly connected to a reinforcing strip 303, which enhances the structural strength of the top of the L-shaped baffle 1. The rear part of the inner wall of the L-shaped baffle 1 is fixedly connected to multiple connecting columns 304. The connecting columns 304 and the limiting plate 305 can help fix the L-shaped baffle 1 and enhance the overall structure. The rear part of the connecting column 304 is fixedly connected to the limiting plate 305, which can block the small displacement of the soil behind the wall to a certain extent.

[0043] Specifically, the trapezoidal groove 301 facilitates climbing by construction workers and is conducive to the inspection and maintenance of the retaining wall. The limiting tube 302 facilitates climbing by construction workers and provides good protection. The reinforcing strip 303 enhances the structural strength of the top of the L-shaped baffle 1 and improves the overall stability. The connecting column 304 and the limiting plate 305 can help fix the L-shaped baffle 1 and enhance the overall structure. At the same time, the limiting plate 305 can block the small displacement of the soil behind the wall to a certain extent.

[0044] Reference Figure 1 , Figure 3 and Figure 5 An L-shaped strip 6 is fixedly connected to the bottom front side of the L-shaped baffle 1. By increasing the structural thickness and support area at the bottom, the bending and shear resistance of the bottom of the L-shaped baffle 1 is effectively improved. A U-shaped block 7 is fixedly connected to the front side of the L-shaped strip 6. The U-shaped block 7 can guide the water flow direction and prevent the water flow from directly scouring the connection between the L-shaped strip 6 and the L-shaped baffle 1. The top edge of the outer wall of the U-shaped block 7 is at the same level as the top edge of the outer wall of the L-shaped strip 6, which can avoid local stress concentration caused by height difference and handle the size of the hollow block 201. The inner wall of the L-shaped baffle 1 is the same size as that of the inner wall, which can filter and discharge the hollow block 201 into the process, and give full play to the function of the drainage mechanism 2. The outer wall of the trapezoidal groove 301 is equally spaced on the front side of the L-shaped baffle 1. The equally spaced arrangement can also make the front side of the L-shaped baffle 1 evenly stressed, avoiding structural damage caused by excessive local stress. The front ends of multiple connecting columns 304 are all equally spaced and fixedly connected to the front side of the inner wall of the L-shaped baffle 1, ensuring that the structure above the connecting columns 304 exerts a uniform force on the L-shaped baffle 1.

[0045] Specifically, the L-shaped strip 6 is fixedly connected to the bottom front of the L-shaped baffle 1. By increasing the structural thickness and support area at the bottom, the bending and shear resistance of the bottom of the L-shaped baffle 1 is effectively improved. The U-shaped block 7 can guide the direction of water flow, preventing water from directly scouring the connection between the L-shaped strip 6 and the L-shaped baffle 1, reducing the risk of structural damage caused by water erosion. Furthermore, the top of the outer wall of the U-shaped block 7 is on the same horizontal plane as the top of the outer wall of the L-shaped strip 6, which can avoid local stress concentration caused by height difference. The size of the hollow block 201 is the same as the inner wall size of the L-shaped baffle 1, which can filter and discharge the water flowing into the hollow block 201, giving full play to the function of the drainage mechanism 2. The equidistant arrangement can also make the front of the L-shaped baffle 1 uniformly stressed, avoiding structural damage caused by excessive local stress. The front ends of multiple connecting columns 304 are all fixedly connected to the front of the inner wall of the L-shaped baffle 1 at equal intervals, ensuring that the structure above the connecting columns 304 exerts uniform stress on the L-shaped baffle 1.

[0046] Working principle: First, the L-shaped baffle 1, as the main structure of the retaining wall, directly bears the lateral pressure from the cut soil. The inclined baffle 4 is set at the top of the L-shaped baffle 1, increasing the obstruction of the cut soil above while reducing material usage. When there is a large amount of water in the cut soil, the hollow block 201 is divided into two parts by the partition plate 202. Sand and gravel are placed above the partition plate 202, and stones are placed below the partition plate 202. Water will pass through the sand and gravel above the partition plate 202 for filtration, and under the action of the filter holes 203 at the top, impurities such as mud and sand will be filtered out. The water will then flow into the stones placed below the partition plate 202 and drain through the drainage outlet 20. 4. Drainage is carried out to avoid excessive water pressure caused by water accumulation behind the wall, and to prevent the soil from softening and becoming unstable due to long-term immersion in water. The reinforcing column 501 and limiting block 502 in the limiting component 5 can limit the displacement of the soil behind the wall, enhance the connection between the soil and the retaining wall, improve the stability of the soil, and prevent the soil from sliding down. The notch 802 on the buffer plate 801 in the buffer component 8 can absorb energy through its own deformation when subjected to external force, alleviate the impact of external force on the retaining wall, and protect the retaining wall structure. At the same time, the drainage channel 901 in the water diversion component 9 collects rainwater above the inclined baffle 4 and drains the water to an area away from the retaining wall through the water diversion channel 902, further reducing the adverse effects of water on the retaining wall.

[0047] Furthermore, the ladder mechanism 3 and the trapezoidal groove 301 facilitate climbing operations for construction personnel and make it easier to inspect and maintain the retaining wall. The limiting tube 302 not only facilitates climbing for construction personnel but also provides effective protection. The reinforcing strip 303 enhances the structural strength of the top of the L-shaped baffle 1 and improves the overall stability. The auxiliary role of the connecting column 304 and the limiting plate 305 is to fix the L-shaped baffle 1 and strengthen the overall structure. In addition, the limiting plate 305 can also suppress the small displacement of the soil behind the wall to a certain extent.
