Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically to a drainage structure for sunken green belts in municipal roads. Background Technology

[0002] The drainage system of municipal roads is an integral part of urban infrastructure. It plays a vital role in the safety of vehicle traffic and pedestrian flow, urban environmental protection, and urban flood control and drainage. The development of the sponge city concept is in line with the need for road drainage optimization.

[0003] Sunken green belts are in line with the development concept of sponge cities. Sunken green belts are green belts whose height is lower than the surrounding ground. The height difference makes it easier for water from roads or sidewalks to flow into the green belt. The open space inside the green belt can receive and store rainwater, thereby reducing runoff. The plants inside are mostly native herbaceous plants.

[0004] A search revealed a utility model patent with publication number CN222205911U, which discloses a sunken green belt drainage structure. The structure includes a driveway and a green belt body connected to the driveway. Curbstones are installed on two opposite sidewalls of the green belt body. Multiple water inlets and outlets are located on the adjacent sidewalls of the two curbstones. Interconnected upper and lower drainage channels are formed within the curbstones. The multiple water inlets are connected to the upper drainage channel, and the multiple water outlets are connected to the lower drainage channel. A connecting groove, communicating with all the water inlets, is formed on the sidewall of the curbstone. A filter screen for blocking fallen leaves and other impurities is installed within the connecting groove. This application improves the drainage capacity of the green belt drainage structure.

[0005] Although the aforementioned patent describes multiple water outlets that are interconnected with the drainage channel, and the connecting channel is equipped with a filter screen to block fallen leaves and other impurities to improve the drainage capacity of the green belt drainage structure, the green belt needs to be watered in dry weather to ensure the survival of the vegetation on the green belt. However, after draining and diverting the accumulated water, the sunken green belt cannot effectively collect rainwater and cannot reuse the rainwater. It requires manual watering of the green belt, resulting in a low survival rate of vegetation and is not conducive to the drainage and storage of accumulated water by the sunken green belt.

[0006] Therefore, it is necessary to propose a drainage structure for sunken green belts in municipal roads to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a drainage structure for sunken green belts in municipal roads. Through the cooperation of the internal parts of the drainage mechanism, rainwater diverted and stored in the main body of the green belt can be recycled. Through the cooperation of the internal parts of the floating mechanism, the water level of the rainwater stored in the water storage layer can be controlled. This ensures that the main body of the green belt still has good drainage and storage performance during the plum rain season. This solves the problem that existing sunken green belts cannot effectively collect rainwater after draining and diverting accumulated water, cannot reuse rainwater, require manual irrigation of the green belt, and have a low survival rate of vegetation. This is not conducive to the drainage and storage of accumulated water in sunken green belts.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a recessed green belt drainage structure for municipal roads, comprising a green belt body, the green belt body being located between roads, with pedestrian walkways on both sides of the green belt body, a drainage mechanism being buried at the bottom of the green belt body and penetrating into the interior of the green belt body, and located at the bottom of the pedestrian walkways, with floating mechanisms connected to both sides of the drainage mechanism and penetrating into the interior of the drainage mechanism;

[0009] The drainage mechanism includes a sand and gravel layer, which is buried at the bottom of the main body of the green belt. A water storage layer is set at the bottom of the sand and gravel layer and buried at the bottom of the sand and gravel layer. Water pumps are bolted to both sides of the outer wall of the water storage layer, and the connection ends penetrate into the interior of the sand and gravel layer. A water delivery pipe is connected and fixed to the output end of the water pump. Drip irrigation pipes are connected and fixed between the water delivery pipes and buried inside the main body of the green belt.

[0010] The floating mechanism includes a drain pipe, which is bolted to both sides of the water storage layer and extends into the interior of the water storage layer. A float plate floats inside the water storage layer between the drain pipes. A sealing plate is provided at the connection between the drain pipe and the inner wall of the water storage layer and is in contact with the inner wall of the water storage layer. A connecting rod is connected between the back of the sealing plate and the two sides of the float plate, and the two ends of the connecting rod are rotatably connected to the back of the sealing plate and the two sides of the float plate respectively through connecting shafts.

[0011] Preferably, the drainage mechanism further includes multiple grating plates, which are installed between the bottom of the sand and gravel layer and the top of the water storage layer. Waterproof plates are attached and fixed to both sides of the outer wall of the water storage layer, and are attached to both sides of the outer wall of the sand and gravel layer and the main body of the green belt, and are buried and fixed at the bottom of the pedestrian road.

[0012] Preferably, the floating mechanism further includes a support shaft, which is rotatably connected to both sides of the inner wall of the water storage layer and rotatably connected to the top of the sealing plate. A torsion spring is sleeved on the outer wall of the support shaft, and both ends are respectively connected and fixed to the sealing plate and the support shaft.

[0013] Preferably, the water pump is installed and fixed on both sides of the outer wall of the water storage layer by a support plate, the surface of the drip irrigation pipe is provided with multiple drip irrigation holes, the pedestrian road is inclined at a certain slope, and the height of the main body of the green belt is 5-10mm lower than the height of the pedestrian road, and multiple fences are installed between the top of the pedestrian road and the main body of the green belt.

[0014] Preferably, the surface of the grating plate is provided with multiple water filtering holes, the interior of the water storage layer is provided with a floating groove that matches the floating plate, and the top of the floating plate is set as a cone shape, and the inner wall of the water storage layer is provided with multiple water storage pools.

[0015] Preferably, one side of the drain pipe is connected to the sewer pipe, a sealing cone is fixed on the surface of the sealing plate near the inner wall of the water storage layer, and the support shaft is rotatably connected to the inner wall of the water storage layer through a bearing.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. The pedestrian walkway is sloped at a certain angle, and the height of the main body of the green belt is 5-10mm lower than that of the pedestrian walkway. This facilitates the flow of water from the pedestrian walkway into the main body of the green belt. The water is initially filtered through the sand and gravel layer and then through the grating plate before flowing into the water storage layer for storage. The grating plate isolates the silt in the sand and gravel layer. At the same time, waterproof plates are installed on both sides of the sand and gravel layer and the main body of the green belt to reduce rainwater infiltration into the foundation of the pedestrian walkway and prevent long-term erosion and collapse of the foundation. During dry seasons, the water stored in the water storage layer can be transported to the drip irrigation pipe by starting the water pump. This allows the drip irrigation pipe to irrigate the vegetation on the main body of the green belt, improving the survival rate of the vegetation on the main body of the green belt during dry seasons. The stored rainwater can be reused, eliminating the need for manual irrigation and reducing the maintenance cost of the green belt.

[0018] 2. As the water level in the water storage layer rises continuously, it pushes the float plate upward. The floating of the float plate causes the sealing plate to move through the connecting rods on both sides. The sealing plate is compressed by the torsion spring, causing it to rotate. This rotation of the sealing plate on both sides of the inner wall of the water storage layer via the support shaft releases the seal between the drainage pipe and the water storage layer, allowing the rising water to flow into the sewer through the drainage pipe. This maintains a certain water level in the water storage layer, ensuring that the main body of the green belt still has good drainage and storage performance during the rainy season.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The above describes a recessed green belt drainage structure for municipal roads, including a green belt body 1 located between roads, with pedestrian walkways 2 on both sides of the green belt body 1. A drainage mechanism 3 is buried at the bottom of the green belt body 1 and extends into the interior of the green belt body 1 and is located at the bottom of the pedestrian walkway 2. Floating mechanisms 4 are connected to both sides of the drainage mechanism 3 and extend into the interior of the drainage mechanism 3.

[0029] The drainage mechanism 3 includes a gravel layer 301, which is buried at the bottom of the main body 1 of the green belt. A water storage layer 302 is provided at the bottom of the gravel layer 301 and is buried at the bottom of the gravel layer 301. Water pumps 305 are bolted to both sides of the outer wall of the water storage layer 302 and the connection ends penetrate into the interior of the gravel layer 301. A water delivery pipe 306 is connected and fixed to the output end of the water pump 305. A drip irrigation pipe 307 is connected and fixed between the water delivery pipes 306 and is buried inside the main body 1 of the green belt.

[0030] The floating mechanism 4 includes a drain pipe 401, which is fixed to both sides of the water storage layer 302 by bolts and extends into the interior of the water storage layer 302. A float plate 402 floats inside the water storage layer 302 and is located between the drain pipes 401. A sealing plate 404 is provided at the connection between the drain pipe 401 and the inner wall of the water storage layer 302 and is in contact with the inner wall of the water storage layer 302. A connecting rod 403 is connected between the back of the sealing plate 404 and the two sides of the float plate 402, and the two ends of the connecting rod 403 are rotatably connected to the back of the sealing plate 404 and the two sides of the float plate 402 respectively through connecting shafts.

[0031] Through the cooperation of the internal parts of the drainage mechanism 3, the accumulated water on the pedestrian road 2 flows into the main body of the green belt 1, and then into the gravel layer 301. After being filtered by the gravel layer 301, the accumulated water can be stored in the water storage layer 302. During dry seasons, the water stored in the water storage layer 302 can be transported to the drip irrigation pipe 307 through the water delivery pipe 306 by the water pump 305 to complete the irrigation of the main body of the green belt 1. Thus, the rainwater diverted and stored in the main body of the green belt 1 can be recycled. Through the cooperation of the internal parts of the floating mechanism 4, the water level of the rainwater stored in the water storage layer 302 can be controlled to keep the water level in the water storage layer 302 constant. This ensures that the main body of the green belt 1 still has good drainage and storage performance during the rainy season.

[0032] Refer to the instruction manual appendix Figure 1-5 The drainage mechanism 3 also includes multiple grating plates 303, which are installed between the bottom of the gravel layer 301 and the top of the water storage layer 302. Waterproof plates 304 are attached and fixed to both sides of the outer wall of the water storage layer 302, and are attached to both sides of the gravel layer 301 and the outer wall of the green belt body 1, and are buried and fixed at the bottom of the pedestrian road 2. Through the cooperation between the internal parts of the drainage mechanism 3, the rainwater diverted and stored by the green belt body 1 can be recycled.

[0033] Refer to the instruction manual appendix Figure 1-5The floating mechanism 4 also includes a support shaft 405, which is rotatably connected to both sides of the inner wall of the water storage layer 302 and rotatably connected to the top of the sealing plate 404. A torsion spring 406 is sleeved on the outer wall of the support shaft 405, and its two ends are respectively connected and fixed to the sealing plate 404 and the support shaft 405. Through the mutual cooperation between the internal parts of the floating mechanism 4, the water level of the rainwater stored in the water storage layer 302 can be controlled, so that the main body of the green belt 1 can still have good drainage and storage performance during the plum rain season.

[0034] Refer to the instruction manual appendix Figure 1-5 The water pump 305 is installed and fixed on both sides of the outer wall of the water storage layer 302 by a support plate. The surface of the drip irrigation pipe 307 is provided with multiple drip irrigation holes. The pedestrian road 2 is inclined at a certain slope, and the height of the green belt body 1 is 5-10mm lower than the height of the pedestrian road 2. Multiple fences are installed between the top of the pedestrian road 2 and the green belt body 1. The pedestrian road 2 is inclined at a certain slope, and the height of the green belt body 1 is 5-10mm lower than the height of the pedestrian road 2. Multiple fences are installed between the top of the pedestrian road 2 and the green belt body 1 to facilitate the flow of water accumulated on the pedestrian road 2 into the green belt body 1 and reduce the water accumulation on the surface of the pedestrian road 2.

[0035] Refer to the instruction manual appendix Figure 1-5 The surface of the grating plate 303 is provided with multiple water filter holes. The interior of the water storage layer 302 is provided with a floating groove that matches the float plate 402, and the top of the float plate 402 is set as a cone. The inner wall of the water storage layer 302 is provided with multiple water storage pools. The floating groove that matches the float plate 402 is provided inside the water storage layer 302, and the top of the float plate 402 is set as a cone, so that rainwater drips onto the top of the float plate 402 and flows into the water storage pool inside the water storage layer 302, and so that the float plate 402 can float up and down in the water storage pool by the buoyancy of the water stored in the water storage pool.

[0036] Refer to the instruction manual appendix Figure 1-5 One side of the drain pipe 401 is connected to the sewer pipe. A sealing cone is fixed on the surface of the sealing plate 404 near the inner wall of the water storage layer 302. The support shaft 405 is rotatably connected to the inner wall of the water storage layer 302 through a bearing. The sealing cone is fixed on the surface of the sealing plate 404 near the inner wall of the water storage layer 302. The support shaft 405 is rotatably connected to the inner wall of the water storage layer 302 through a bearing. This allows the support shaft 405 to rotate and drive the sealing plate 404 to penetrate into the inner wall of the drain pipe 401, so that the sealing plate 404 seals the drain pipe 401 and the water storage layer 302 through the sealing cone.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-5The pedestrian walkway 2 slopes at a certain angle, and the height of the main body of the green belt 1 is 5-10mm lower than that of the pedestrian walkway 2. This facilitates the flow of accumulated water from the pedestrian walkway 2 into the main body of the green belt 1. The accumulated water flows into the main body of the green belt 1 and undergoes preliminary filtration through the sand and gravel layer 301. Then, it flows through the grating plate 303 and into the water storage layer 302 for storage. The grating plate 303 can isolate the silt and sand in the sand and gravel layer 301. At the same time, waterproof plates 3 are installed on both sides of the sand and gravel layer 301 and the main body of the green belt 1. 04. This can reduce rainwater infiltration into the foundation of pedestrian road 2, preventing long-term erosion and collapse of the foundation. During dry seasons, by starting the water pump 305, the water stored in the water storage layer 302 can be transported to the drip irrigation pipe 307 through the water delivery pipe 306, which can then irrigate the vegetation of the main body of the green belt 1, improve the survival rate of the vegetation on the main body of the green belt 1 during dry seasons, and reuse the stored rainwater. There is no need for artificial irrigation, which reduces the cost of green belt maintenance.

[0039] Refer to the instruction manual appendix Figure 1-5 As the water level in the water storage layer 302 rises continuously, it pushes the float plate 402 upward. The float plate 402 floats and drives the sealing plate 404 to move through the connecting rods 403 on both sides. The sealing plate 404 is compressed by the torsion spring 406 and rotates, causing the sealing plate 404 to rotate on both sides of the inner wall of the water storage layer 302 through the support shaft 405. The rotation of the sealing plate 404 can release the seal between the drainage pipe 401 and the water storage layer 302, allowing the rising water to flow into the sewer through the drainage pipe 401. This keeps the water level in the water storage layer 302 at a certain level, so that the main body of the green belt 1 can still have good drainage and storage performance during the rainy season.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
