Description

Technical Field

[0001] The present application relates to the technical field of road engineering, and in particular to a permeable curbstone for improving the control rate of the total annual runoff volume in a sponge city. Background Art

[0002] Existing curbstones only allow rainwater to flow horizontally through the road's cross slope into sunken green spaces or simple bioretention facilities. Unlike permeable pavement, they do not allow rainwater to flow vertically into these spaces through infiltration. Therefore, when calculating the annual runoff control rate for a sponge city, the combined rainfall runoff coefficient for ordinary curbstones is typically 0.8, significantly higher than the 0.36 combined rainfall runoff coefficient for permeable sidewalks and non-motorized vehicle lanes. This reduces the sponge city's annual runoff control rate.

[0003] At present, the existing permeable curbs have openings or cavities on the curb body. In essence, the curb is used as a pipe to allow rainwater to flow horizontally into the sunken green space or simple bioretention facilities without hindrance. It does not have the ability to infiltrate vertically. Utility Model Content

[0004] In order to improve the problem that existing curbstones do not have the ability to penetrate vertically, the present application provides a permeable curbstone that improves the control rate of the total annual runoff volume in sponge cities.

[0005] This application provides a permeable curb stone that improves the annual runoff control rate of sponge cities using the following technical solutions:

[0009] By adopting the above technical solution, the permeable setting of the seepage part allows rainwater to seep directly into the ground, which will increase the longitudinal infiltration capacity of rainwater, thereby improving the annual runoff control rate of the sponge city. The water storage part can form a pipeline for rainwater to flow horizontally and store part of the rainwater.

[0010] Preferably, a slope is provided on one side of the water seepage portion.

[0014] Preferably, there are two water flow gaps, which are respectively distributed on the tops of the side walls on both sides in the width direction of the water storage part.

[0015] By adopting the above technical solution, when the rainwater in the water reservoir accumulates to a certain level, the water storage part can discharge the excess rainwater through the water flow gap to prevent the rainwater from overflowing from the infiltration part.

[0016] Preferably, a filter screen is provided between the water storage part and the water seepage part.

[0017] By adopting the above technical solution, the filter net can perform preliminary filtration on the water flowing through it, reduce the pollutants that directly enter the seepage part, and help improve the water quality.

[0018] Preferably, it further comprises a blocking plate, wherein the blocking plate is fixedly connected to the water storage part, and one end of the blocking plate passes through the water storage part.

[0019] By adopting the above technical solution, the blocking plate can reduce the direct impact of water flow on the water storage part, and help to form a local shelter space, reduce the evaporation of water after rain, and effectively retain rainwater.

[0020] Preferably, a gap is left between the side wall of the baffle plate located in the water storage portion and the side wall of the water storage portion.

[0021] By adopting the above technical solution, rainwater can flow into the reservoir through the gap.

[0022] Preferably, the blocking plate is bent.

[0023] By adopting the above technical solution, the bent blocking plate can guide the water flow, thereby reducing the impact of the water flow on the water storage part.

[0024] Preferably, a water diversion channel is provided in the baffle plate, and the water diversion channel passes through the baffle plate. One end of the water diversion channel is communicated with the external environment, and the other end of the water diversion channel is communicated with the water reservoir.

[0025] By adopting the above technical solution, the water diversion channel can divert rainwater in the reservoir out of the reservoir, thereby improving the utilization efficiency of water resources.

[0026] Preferably, a plurality of capillaries are provided in the water diversion channel.

[0027] By adopting the above technical solution, rainwater can rise through the capillary tube and overflow the water diversion channel, thereby realizing autonomous flow of water.

[0039] The following is combined with Figure 1-6 This application is described in further detail.

[0040] The present application discloses a permeable curbstone that improves the total annual runoff control rate of a sponge city. Figure 1 and Figure 2 The permeable curb that improves the annual runoff control rate of the sponge city includes a seepage part 1 and a water storage part 2.

[0041] like Figure 1 As shown, the seepage part 1 is permeable and semi-buried on the ground, and a slope is provided on one side of the seepage part 1. Specifically, the seepage part 1 is a permeable concrete block cast through a mold. The permeable concrete allows rainwater to seep vertically, so that the curbstone has the ability to allow rainwater to seep vertically, improving the problem that the existing curbstone does not have the ability to seep vertically. The slope of the seepage part 1 helps to guide the sight of drivers and pedestrians, improve the recognizability of the road, and thus improve safety.

[0042] like Figure 3 and Figure 4 As shown, the water storage part 2 is buried underground, the top of the water storage part 2 is fixedly connected to the bottom of the water seepage part 1, and the water storage part 2 is provided with a water reservoir 21 connected to the water seepage part 1, the opening of the water reservoir 21 faces upward, and the side wall of the water storage part 2 is provided with a water flow gap 22; in the embodiment of the present application, the water flow gap 22 is provided at the upper part of the side wall of the water storage part 2, and there are two water flow gaps 22, which are respectively provided on both sides of the water storage part 2. When the rainwater in the water reservoir 21 accumulates to a certain extent, the water storage part 2 can discharge excess rainwater through the water flow gap 22 to prevent rainwater from overflowing from the seepage part.

[0043] Optionally, the water storage part 2 is made by pouring waterproof concrete.

[0044] In another embodiment, the water storage part 2 is made by pouring waterproof concrete, and a steel skeleton is provided in the waterproof concrete to improve the structural strength of the water storage part 2 .

[0045] Specifically, several permeable curbs that improve the annual runoff control rate of the sponge city are connected to form a dividing strip, which can quickly reduce road surface water when it rains. The permeable setting of the seepage part 1 allows rainwater to seep directly into the ground, which will increase the longitudinal infiltration capacity of rainwater, thereby improving the annual runoff control rate of the sponge city. The water storage part 2 can form a pipeline for rainwater to flow horizontally and store some rainwater.

[0046] In an embodiment of the present application, a filter screen 4 is provided between the water storage part 2 and the seepage part 1. The filter screen 4 can perform preliminary filtration on rainwater flowing into the seepage part 1, thereby reducing the direct entry of debris into the seepage part 1 and helping to improve water quality.

[0047] like Figure 5 and Figure 6As shown, the water storage part 2 is further provided with a blocking plate 3, one end of the blocking plate 3 passes through the side wall of one side of the water storage part 2 and is fixedly connected to the water storage part 2, and a gap is left between the side wall of the blocking plate 3 located inside the water storage part 2 and the side wall of the water storage part 2; rainwater can flow into the water storage tank 21 through the gap, and the blocking plate 3 can reduce the direct impact of rainwater on the water storage part 2, and help to form a local sheltered space, reduce the evaporation of water after rain, and effectively retain rainwater.

[0048] The baffle plate 3 is bent, and a water diversion channel 31 is provided in the baffle plate 3. The water diversion channel 31 passes through the baffle plate 3, connects the water reservoir 21 and the external environment, and a plurality of capillaries 32 are provided in the water diversion channel 31. The bent baffle plate 3 can guide the water flow, thereby reducing the impact of the water flow on the water storage part 2. The water diversion channel 31 can divert rainwater in the water reservoir 21 out of the water reservoir 21 through the capillaries 32, thereby improving the utilization efficiency of water resources.

[0049] Specifically, one end of the blocking plate 3 passes through the water storage part 2, and the other end of the blocking plate 3 is bent and extends downward until it extends to the lower part of the water reservoir 21; when the water reservoir 21 stores rainwater after rain, the blocking plate 3 can block part of the evaporated water vapor, so that the water vapor forms droplets on the surface of the blocking plate 3 and eventually falls into the water reservoir 21, reducing the evaporation of rainwater; and, when the water reservoir 21 stores rainwater after rain, a number of capillaries 32 rise through capillary action and overflow the water diversion channel 31. The rainwater overflowing the water diversion channel 31 can be used to irrigate the surrounding green belts, thereby improving the utilization efficiency of water resources while realizing the autonomous flow of water.

[0050] It should be noted that the capillary tube 32 in the embodiment of the present application is specifically a hose, which is filled with capillary material, and the capillary material is specifically collodion or sponge. When the rainwater in the water reservoir 21 is drawn out by capillary action, no external energy is required, which has the advantages of energy saving and low cost.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
