[0031] In order to cope with the risk of urban waterlogging, promptly discharge rainwater that exceeds the city's flood control standards and reduce the harm of floods to the city, it is necessary to consider setting up urban rainwater discharge channels when planning the overall urban layout.
[0032] In the related art, rainwater flood discharge channels are either not considered during urban planning, or rainwater flood discharge channels are constructed from within or outside the city.
[0033] Setting up rainwater flood discharge channels in the city, when a flood occurs, the flood discharge through the city roads can still cause certain property losses and serious environmental pollution. When using rivers to set up rainwater flood discharge channels, not only is there a lack of certain landscape, but also because floods are not easy to occur, the rainwater flood discharge channels occupy too much land, resulting in low land resource utilization.
[0034] In order to solve the problem of unsightly rainwater discharge channels currently set up in cities and the resulting low land resource utilization rate, an embodiment of the present application provides an integrated urban flood drainage landscape structure. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.
[0035] Figure 1 It is a schematic diagram of an integrated urban flood drainage landscape structure provided in one embodiment of the present application.
[0036] Reference Figure 1 As shown, an embodiment of the present application provides an integrated urban flood drainage landscape structure, including a water passage 100.
[0037] The two sides of the water passage 100 are respectively connected with the leisure part 200, the pedestrian walkway 300, the non-motor vehicle lane 900, the greening storage part 400 and the motor vehicle lane 500 in sequence. The height of the leisure part 200 is greater than the height of the water passage 100, the height of the pedestrian walkway 300 is greater than the height of the leisure part 200, the height of the pedestrian walkway 300 is the same as the height of the non-motor vehicle lane 900, the height of the greening storage part 400 is greater than the height of the non-motor vehicle lane 900, and the height of the greening storage part 400 is the same as the height of the motor vehicle lane 500; and the greening storage part 400 is connected with the water passage 100 through a pipeline.
[0038] Specifically, the motor vehicle lane 500 is not less than 2m higher than the non-motor vehicle lane 900 and the pedestrian walkway 300, and the non-motor vehicle lane 900 and the pedestrian walkway 300 are not less than 2m higher than the recreational area 200. Exemplarily, the height of the motor vehicle lane 500 is 2m higher than the height of the non-motor vehicle lane 900 and the pedestrian walkway 300, and the height of the non-motor vehicle lane 900 and the pedestrian walkway 300 is 2m higher than the height of the recreational area 200.
[0039] Among them, the leisure part 200 is a leisure area, which can be a leisure platform or a leisure square. The pedestrian walkway 300 is a road for pedestrians to walk. The non-motorized vehicle lane 900 is a road for non-motorized vehicles to travel. The motor vehicle lane 500 is a road for motor vehicles to travel. Green plants are planted in the greening storage part 400, and rainwater flowing out of the motor vehicle lane 500 can be filtered and discharged, which has good ecological and environmental benefits.
[0040] It can be understood that the leisure part 200, the pedestrian walkway 300, the non-motorized vehicle lane 900, the greening storage part 400 and the motor vehicle lane 500 in the integrated structure of the urban flood drainage landscape can meet the functions of people's passage and entertainment when there is no flood, and the greening storage part 400 is ornamental. When a flood occurs, the leisure part 200, the non-motorized vehicle lane 900 and the pedestrian walkway 300 can all be used as flood discharge channels to provide a greater flood discharge capacity, meet the city's flood discharge requirements, and solve the problem of the unsightly rainwater flood discharge channels currently set up in the city and the low land resource utilization rate caused by them.
[0041] Specifically, the width of the non-motorized vehicle lane 900 is not less than 2.5 m; the width of the pedestrian walkway 300 is not less than 2.5 m; the width of the recreation area 200 is not less than 2 m; and the flow capacity of the water passage 100 is not less than the flood volume under the urban flood control standard.
[0042] Exemplarily, the width of the non-motorized vehicle lane 900 is 2.5 m; the width of the pedestrian walkway 300 is 2.5 m; the width of the recreational area 200 is 2.5 m; the flow capacity of the water passage 100 meets the city's flood volume once in 50 years; when the flood inundates the recreational area 200 and reaches the pedestrian walkway 300, the city's flood volume once in 100 years is met; when the flood inundates the non-motorized vehicle lane 900 and the pedestrian walkway 300 to the greening storage area 400, the city's flood volume once in 150 years is met.
[0043] The leisure department 200 may have leisure and entertainment facilities such as fishing chairs and sports equipment.
[0044] Continue to refer to Figure 1 As shown, in some examples, a non-motorized vehicle crossing road 410 is disposed across the greenery storage section 400, so that non-motorized vehicles can pass through the greenery storage section 400 to reach other areas.
[0045] Figure 2 yes Figure 1 Schematic diagram of the structure of the greening storage unit 400.
[0046] In addition, refer to Figure 2As shown, the integrated structure of urban flood drainage landscape includes a first step 800, which is arranged in the greening storage part 400, one end of the first step 800 is connected to the non-motor vehicle crossing road 410, and the other end of the first step 800 is connected to the non-motor vehicle road 900. In other words, the first step 800 connects the non-motor vehicle crossing road 410 with the non-motor vehicle road 900, so that the non-motor vehicle can reach the non-motor vehicle road 900 from the motor vehicle road 500 through the non-motor vehicle crossing road 410 and the first step 800. In addition, illustratively, the first step 800 includes a pedestrian step and a non-motor vehicle transition slope, and pedestrians can reach the non-motor vehicle crossing road 410 from the non-motor vehicle road via the pedestrian step, and the non-motor vehicle can reach the non-motor vehicle crossing road 410 from the non-motor vehicle road via the non-motor vehicle transition slope. That is, the first step 800 has the ability of pedestrians and non-motor vehicles to pass.
[0047] Continue to refer to Figure 1 As shown, the integrated urban flood drainage landscape structure further includes a second step 700, one end of which is connected to the pedestrian walkway 300, and the other end of which is connected to the recreational area 200, so as to ensure that pedestrians can reach the recreational area 200 from the pedestrian walkway 300 for activities. The second step 700 has the ability for pedestrians to pass through.
[0048] Continue to refer to Figure 2 As shown, the greening storage part 400 includes a planting soil layer 420, a first permeable layer 430 and a second permeable layer 440 stacked in sequence from top to bottom, wherein the voids in the first permeable layer 430 are smaller than the voids in the second permeable layer 440, and can filter the water flowing from the motor vehicle lane 500 to the greening storage part 400. In some examples, the planting soil layer 420 is also provided with a water storage planting layer; the planting soil layer 420 is soil with a porosity of 0.001cm / s and a thickness of 0.3m, and aquatic and amphibious plants and road landscape trees are planted in the water storage planting layer and the planting soil layer 420, which can play the role of both water storage and greening. The first permeable layer 430 is paved with coarse sand with a particle size of less than 5cm, and the second permeable layer 440 is paved with gravel with a diameter of 40-50cm and a thickness of 0.3m.
[0049] Continue to refer to Figure 2 As shown, the greening storage section 400 also includes a slope retaining wall 450, which is located on the side of the planting soil layer 420 close to the non-motorized vehicle lane 900, and is used to block and stabilize the planting soil layer 420, the first permeable layer 430 and the second permeable layer 440, while preventing rainwater from flowing out of the planting soil layer 420, the first permeable layer 430 and the second permeable layer 440.
[0050] Continue to refer to Figure 2As shown, the integrated urban flood drainage landscape structure further includes a drainage pipe 600, the greening storage part 400 further includes a rainwater overflow well 460, the planting soil layer 420, the first permeable layer 430 and the second permeable layer 440 are arranged around the outer wall of the rainwater overflow well 460, and the upper edge of the rainwater overflow well 460 protrudes from the planting soil layer 420. When the rainwater is too heavy and the water surface exceeds the upper edge of the rainwater overflow well 460, a large amount of rainwater will enter the rainwater overflow well 460 and flow to the water passage 100 through the drainage pipe 600.
[0051] Continue to refer to Figure 1 and Figure 2 As shown, a filter grille 462 is provided in the rainwater overflow well 460, and the filter grille 462 is arranged at the end of the drain pipe 600, so as to filter impurities in the rainwater to avoid clogging the drain pipe 600. The grid spacing of the filter grille 462 can range from 1 cm to 3 cm.
[0052] In addition, continue to refer to Figure 2 As shown, a silt settling area 461 is provided in the rainwater overflow well 460, and silt is also deposited in the silt settling area 461 to prevent the silt from being too deep and blocking the pipe opening of the drainage pipe 600. The depth of the silt settling area 461 is not less than 0.5m. Exemplarily, in some examples, the silt settling area in the rainwater overflow well 460 is 0.5m deep, and the spacing between the bars is 1cm.
[0053] In some examples, the water channel 100 is paved with a gravel layer to prevent rainwater or floods from excessively scouring the bottom of the water channel 100 .
