Description

Technical Field

[0001] This utility model relates to the field of soil stabilization technology for green landscape belts, and in particular to a soil stabilization system for green landscape belts. Background Technology

[0002] In the field of municipal road stormwater management, the traditional design of directly receiving road runoff through green belts has significant flaws. High-speed rainwater carrying large amounts of silt, road debris, and initial pollutants flows into the green belts without pretreatment, causing severe erosion of the planting soil. This not only reduces plant survival rates but also leads to soil overflow and road contamination. Simultaneously, solid impurities clog the pores of bioretention facilities, weakening rainwater infiltration and purification efficiency, necessitating frequent dredging and maintenance. While conventional diversion to stormwater drainage networks avoids green belt erosion, it misses the opportunity for rainwater resource utilization and exacerbates the load on the drainage network. Existing technologies struggle to simultaneously achieve the triple goals of "soil and water conservation, pollution control, and ecological infiltration," necessitating a collaborative treatment mechanism that can reduce kinetic energy and separate impurities before rainwater enters the green belts. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a soil stabilization scheme for green landscape belts that achieves kinetic energy reduction and impurity separation before rainwater enters the green belt.

[0004] The technical solution of this utility model is as follows: a soil stabilization system for green landscape belts, including a sidewalk and a bioretention zone. Reinforcing granite is laid between the sidewalk and the bioretention zone. Separating granite is laid inside the bioretention zone. A pebble buffer zone is laid inside the separating granite. Multiple drainage channels are provided on the sidewalk. The outlet of the drainage channel is connected to the inlet of the pebble buffer zone. The outlet of the pebble buffer zone extends into the bioretention zone.

[0005] A sedimentation separation structure is provided inside a drainage trough. The sedimentation separation structure includes a sedimentation tank and a flow tank inside the drainage trough, and the sedimentation tank and the flow tank are connected by multiple drainage pipes.

[0006] Optionally, the bottom of the sedimentation tank is lower than the bottom of the flow tank, and the drain pipe is inclined.

[0007] Optionally, a protective grille may be detachably installed on the top of the drainage channel, and the aperture of the protective grille is 2 to 5 mm.

[0008] Optionally, a collection basket is installed in the sedimentation tank, and the collection basket is provided with a drain hole that communicates with a drain pipe.

[0009] Optionally, the depth of the drainage trough is 5-15cm and the width is 8-20cm.

[0010] Optionally, the pebble buffer zone includes a bottom layer of permeable geotextile and a pebble layer filling the top of the permeable geotextile.

[0011] Optionally, the permeable pavement for the sidewalk consists of a permeable surface layer, a permeable leveling layer, and a permeable base layer from top to bottom, wherein the permeable base layer is connected to the soil layer of the bioretention zone.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] By installing cobblestone speed bumps, the impact of rainwater can be reduced, allowing rainwater to flow safely into the bioretention zone. This effectively protects the soil in the bioretention zone from being washed away, providing a good growing environment for plants. At the same time, it keeps the road clean, allows rainwater to replenish groundwater more effectively and be purified, and the structure is simple, effective, economical and environmentally friendly.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Example

[0020] like Figures 1 to 3 As shown, the present invention proposes a soil stabilization system for green landscape belts, including a sidewalk 1 and a bioretention zone 2. The bioretention zone 2 is lower than the sidewalk 1 to facilitate rainwater inflow. The soil is enriched with sand, organic matter, etc., to make rainwater infiltrate more easily. Drought-resistant and flood-resistant plants are planted on the bioretention zone 2. The root system of the plants helps to absorb rainwater, stabilize the soil, and purify the water.

[0021] The permeable pavement of pedestrian walkway 1 consists of a permeable surface layer, a permeable leveling layer, and a permeable base layer from top to bottom. The permeable base layer is connected to the soil layer of bioretention zone 2. Water passing through pedestrian walkway 1 can infiltrate into the interior of bioretention zone 2. Reinforcing granite 3 is laid between pedestrian walkway 1 and bioretention zone 2. Separating granite 4 is laid inside bioretention zone 2. The reinforcing granite 3 and separating granite 4 clearly separate pedestrian walkway 1 and bioretention zone 2, and can reinforce the edges to prevent soil erosion or structural collapse, and provide a neat appearance.

[0022] In this embodiment, a pebble buffer strip 5 is laid inside the separating granite 4. The pebble buffer strip 5 includes a bottom layer of permeable geotextile and a pebble layer filled on top of the permeable geotextile. The uneven surface of the pebble layer and the gaps between them will greatly slow down the speed of rainwater flow. The pebble layer consumes part of the impact force of the water flow through friction and obstruction. Since the impact force of the water flow is reduced, the ability of the water flow to wash away soil is weakened, which can effectively prevent soil erosion and protect the green belt. When rainwater passes through the gaps between the pebbles, some small mud and sand and debris washed down from the road may be partially intercepted in the gaps between the pebbles, which plays a filtering role.

[0023] Furthermore, multiple drainage channels 6 are provided on the sidewalk 1. The drainage channels 6 are 5-15cm deep and 8-20cm wide. The outlet of the drainage channel 6 is connected to the inlet of the pebble buffer zone 5. The outlet of the pebble buffer zone 5 extends into the bioretention zone 2. Rainwater from the sidewalk 1 is collected by the drainage channels 6 and enters the pebble buffer zone 5. The rainwater is slowed down and dissipated by the pebble layer and slowly released to infiltrate and purify into the bioretention zone 2.

[0024] like Figures 1 to 3 As shown, this embodiment also includes a sedimentation and separation structure located inside the drainage ditch 6. The sedimentation and separation structure includes a sedimentation tank 8 and a flow channel 9 inside the drainage ditch 6. Rainwater will first flow into the sedimentation tank 8 and then into the flow channel 9. In the sedimentation tank 8, the sand and mud in the rainwater will settle to the bottom of the drainage ditch 6 under gravity. The bottom of the sedimentation tank 8 is lower than the bottom of the flow channel 9, which requires the rainwater in the sedimentation tank 8 to rise before entering the flow channel 9. This enhances the filtration effect on the sand and gravel in the rainwater. Between the sedimentation tank 8 and the flow channel 9... The system is connected by multiple drainage pipes 10. When the rainwater level inside the sedimentation tank 8 is higher than the highest point of the drainage pipe 10, the rainwater inside the sedimentation tank 8 can enter the flow channel 9 through the drainage pipe 10. The drainage pipe 10 is inclined, which allows the sand and gravel entering the drainage pipe 10 to roll downwards into the sedimentation tank 8 under its own weight. The sedimentation tank 8 can intercept silt in advance, ensuring the efficient operation of the biological purification system. During heavy rain, the water flow has an enhanced ability to carry impurities. Large particles can be quickly settled through the sedimentation tank 8, preventing the system from collapsing during peak periods.

[0025] The top of the drainage trough 6 is detachably equipped with a protective grille 7. The grille 7 has a hole diameter of 2-5mm. The protective grille 7 filters impurities on the sidewalk and prevents impurities from entering the sedimentation tank 8 and affecting the drainage effect of the drainage trough 6.

[0026] In this embodiment, a collection basket 11 is installed in the sedimentation tank 8. The collection basket 11 is provided with a drain hole that communicates with the drain pipe 10. As the usage time increases, sand and mud will gradually be pushed into the sedimentation tank 8. At this time, it is necessary to clean these sand and gravel. When cleaning, the protective grid 7 needs to be opened and the collection basket 11 needs to be lifted out to remove the sand and gravel from the sedimentation tank 8, which facilitates the maintenance of the sedimentation tank 8.

[0027] In this embodiment, rainwater from the sidewalk 1 is collected by the drainage trough 6 and first flows into the sedimentation tank 8. After passing through the sedimentation tank 8, it enters the flow channel 9. In the sedimentation tank 8, the sand and mud in the rainwater will settle to the bottom of the drainage trough 6 under the action of gravity. When the rainwater level in the sedimentation tank 8 is higher than the highest point of the drainage pipe 10, the rainwater in the sedimentation tank 8 can enter the flow channel 9 through the drainage pipe 10. Subsequently, the rainwater enters the pebble buffer zone 5, where it is slowed down and dissipated by the pebble layer. The rainwater then slowly infiltrates into the bioretention zone 2 for infiltration and purification.
