Description

Technical Field

[0001] The utility model relates to the technical field of ground engineering, in particular to a water-guiding structure combined with an edge stone and a sunken green space with a purification function. Background Art

[0002] When setting a curbstone between an existing road and a sunken green space, the conventional practice is as shown in the attached figure on pages 3-14 of the National Standard Atlas 15MR105 "Rainwater Facilities for Low-Impact Development of Urban Roads and Open Spaces". The curbstone is opened with holes to allow surface water to flow into the sunken green space through the water holes. This method of directly discharging runoff generated by the road surface into the sunken green space does not comply with Article 8.0.5 of the "Garden Greening Project Specifications" GB 55014-2021, which states that initial runoff rainwater from the road that has not been purified shall not be directly discharged into the road green belt.

[0003] When water flows directly into the sunken green space along the slope, the runoff will scour the slope, affect the growth of plants on the slope, and cause the slope to collapse. If the green space is close to the road, the visual effect is not good, and it is easy to cause psychological pressure on people passing by on the road that they are prone to slipping.

[0028] Combine the following Figures 1 to 3 , the edge stone and sunken green space combined water guide structure 100 with purification function provided in the embodiment of the present application is described in detail through specific embodiments.

[0029] Please also read Figures 1 to 3 , Figure 1 It is a plan view of a water-guiding structure combined with a vertical edge stone and a sunken green space with a purification function provided by the utility model; Figure 2 It is a structural schematic diagram of the curbstone provided by the utility model; Figure 3It is a plan view of the curb provided by the utility model. The curb and sunken green space combined water guide structure 100 with purification function provided in one embodiment of the utility model comprises a road surface 10, a curb 20 and a sunken green space 30. The curb 20 is arranged on the road surface 10, and a slope is formed between the curb 20 and the road surface 10. The accumulated water on the road surface 10 can flow to the curb 20 through the slope between the curb 20 and the road surface 10; the sunken green space 30 is located on the water outlet side of the curb 20; wherein the curb 20 can buffer the accumulated water flowing in from the road surface 10.

[0030] When it rains, water may accumulate on the ground. The curbstone 20 is arranged on the road surface 10, and an inclined slope is formed between the curbstone 20 and the road surface 10, so that the accumulated water on the road surface 10 can flow to the curbstone 20 through this slope. The sunken green space 30 is located on the water outlet side of the curbstone 20, and the water flowing through the curbstone 20 can enter the sunken green space 30 through the water outlet side of the curbstone 20. Among them, the curbstone 20 can buffer the accumulated water flowing in from the road surface 10, so that the accumulated water can be properly buffered and purified before flowing into the sunken green space 30. In this way, a large amount of accumulated water can be prevented from directly flowing into the sunken green space 30, reducing the scouring and silting phenomenon inside the sunken green space 30, and preventing the growth of slope plants from being affected and causing slope collapse.

[0031] The curb 20 is located on the ground, so that a clear partition is formed between the road surface 10 and the sunken green space 30 next to it, preventing people walking or riding on the road from sliding into the sunken green space 30.

[0032] In some embodiments, the curb 20 includes a water inlet 21, which faces the road surface 10 and is flush with the road surface 10. The curb 20 has a water inlet 21. The water inlet 21 faces the road surface 10 and is flush with the road surface 10, that is, the water inlet 21 and the road surface 10 are horizontally arranged. The accumulated water on the road surface 10 can enter the curb 20 through the water inlet 21. By arranging the water inlet 21 on the curb 20, the accumulated water on the road surface 10 can be conveniently collected, so that the accumulated water can smoothly flow from the road surface 10 into the curb 20. At the same time, the water inlet 21 is arranged flush with the road surface 10, which can ensure that the accumulated water can smoothly enter the curb 20, avoiding the problem of accumulated water being blocked or lost due to the horizontal plane difference.

[0033] In some embodiments, the curb 20 is provided with a collection and distribution gravel layer 22, and the collection and distribution gravel layer 22 is located below the water inlet 21. By providing the collection and distribution gravel layer 22, the effect of the curb 20 in treating accumulated water can be further improved. The collection and distribution gravel layer 22 can play the role of filtering pollution, fixing and regulating water flow. When the accumulated water enters the curb 20 through the water inlet 21, the collection and distribution gravel layer 22 will play a filtering role, intercepting suspended matter and impurities, so that the pollutants in the accumulated water are removed to a certain extent. At the same time, the collection and distribution gravel layer 22 can also play the role of fixing the water flow, slowing down the speed of the water flow, reducing the impact force of the water flow, and preventing the water flow from damaging the green space. In addition, the collection and distribution gravel layer 22 can also regulate the water flow, so that the water flow flows evenly to the sunken green space 30, avoiding the problem of excessive water accumulation in the green space due to concentrated inflow of water.

[0034] In some embodiments, a green space transition zone 40 is also included, and the green space transition zone 40 is located between the curb 20 and the sunken green space 30. The green space transition zone 40 provides a smooth transition area between the curb 20 and the sunken green space 30. The green space transition zone 40 can play a role of connection and connection, so that the water flow can flow smoothly from the curb 20 into the sunken green space 30, avoiding blockage or overflow of the water flow. At the same time, the green space transition zone 40 can also balance the speed and impact of the water flow, so that the water flow can gradually slow down before entering the sunken green space 30, and maintain a suitable water flow speed to avoid scouring and damage to the green space. In addition, the green space transition zone 40 can also provide a suitable environment and conditions to promote the growth and development of vegetation. It can provide an appropriate amount of water source and humidity to provide sufficient water and nutrients for the vegetation in the sunken green space 30. At the same time, the green space transition zone 40 can also filter, purify and maintain water quality to ensure that the water flow entering the sunken green space 30 has a certain purification effect.

[0035] In some embodiments, a water pipe 41 is provided at the bottom of the green space transition zone 40, one end of the water pipe 41 is connected to the collection and distribution gravel layer 22, and the other end is connected to the sunken green space 30. A water pipe 41 is provided at the bottom of the green space transition zone 40. The water pipe 41 can guide the water flow from the green space transition zone 40 to the sunken green space 30. One end of the water pipe 41 is connected to the collection and distribution gravel layer 22, so that the water flow can be smoothly flowed from the collection and distribution gravel layer 22 into the water pipe 41. The collection and distribution gravel layer 22 plays a role in filtering and fixing the water flow, intercepting suspended matter and impurities, and making the water flow cleaner. The connection of the water pipe 41 can ensure that the water flow smoothly passes through the collection and distribution gravel layer 22 into the water pipe 41. The water pipe 41 at the other end is connected to the sunken green space 30. Through the guidance of the water pipe 41, the water flow can smoothly flow into the sunken green space 30. This ensures that the water flow is evenly distributed in the sunken green space 30, ensuring that the vegetation in the green space is adequately hydrated, and is conducive to the penetration of water into the soil, promoting the growth and development of vegetation. By setting the water guide pipe 41, the flow direction and distribution of the water flow can be better guided and controlled to ensure the normal operation and purification effect of the entire combined water guide structure.

[0036] In some embodiments, an overflow rainwater outlet 50 is also included, and the overflow rainwater outlet 50 is arranged on the sunken green space 30. When the water level inside the sunken green space 30 is too high, the overflow rainwater outlet 50 can discharge the excess rainwater inside the sunken green space 30 to avoid excessive water accumulation inside the sunken green space 30. When the water level inside the sunken green space 30 exceeds a certain threshold, the overflow rainwater outlet 50 will automatically open and discharge the excess rainwater into the designated drainage system. This can prevent the problem of vegetation lodging, soil waterlogging and green space damage caused by the water level of the sunken green space 30 being too high. By setting the overflow rainwater outlet 50, the water level inside the sunken green space 30 can be guaranteed to be within an appropriate range, and an effective channel can be provided for subsequent rainwater discharge. The setting of the overflow rainwater outlet 50 also helps to protect the ecological environment inside the green space and avoid the problem of plant decay and water pollution caused by water retention.

[0037] In some embodiments, the thickness of the aggregated gravel layer 22 is 50 cm. The thickness of the aggregated gravel layer 22 is 50 cm. The 50 cm thickness can provide enough space to filter and fix the water flow. The aggregated gravel layer 22 can filter pollutants, purify water quality and fix the water flow speed. Through a certain thickness of the aggregated gravel layer 22, the filtering and purification effects can be increased, and the suspended matter and impurities in the water flow can be better removed. At the same time, sufficient thickness can also slow down the water flow speed, reduce the impact of the water flow, and prevent the water flow from damaging the green space.

[0038] In some embodiments, the width of the green space transition zone 40 is not less than 1 m. A width of more than 1 m can provide enough space to achieve a smooth transition between the curb 20 and the sunken green space 30. When the width of the green space transition zone 40 is wide enough, it can ensure that water flows smoothly from the curb 20 into the sunken green space 30, avoiding blockage or overflow of water flow. A wider green space transition zone 40 can also provide more ecological space and conditions for vegetation growth. The green space transition zone 40 can accommodate more plants, promote better ecosystem development, and provide better landscape effects.

[0039] In some embodiments, the water pipe 41 is made of UPVC material, and the inner diameter of the water pipe 41 is 100 mm. UPVC material, i.e., Unplasticized Polyvinyl Chloride, is a common plastic material. It has excellent chemical resistance, corrosion resistance, and heat resistance, and also has high rigidity and strength. By setting the water pipe 41 of UPVC material, the water pipe 41 is suitable for water treatment and drainage systems. The inner diameter of the water pipe 41 is 100 mm. With an inner diameter of 100 mm, the water pipe 41 can provide sufficient flow and channel to ensure that the water flows smoothly from the aggregate gravel layer 22 into the sunken green space 30 or other drainage systems.
