Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage technology, and in particular to a novel rainwater storage module for use in the median strip of municipal roads. Background Technology
[0002] The construction of sponge cities has yielded good engineering benefits in the development and construction of parks, green spaces, public buildings, and residential communities. However, it faces certain difficulties in the construction of sponge cities for municipal roads. Due to limited green space and the fact that the water volume in low-impact facilities such as bioretention strips is closely related to rainfall, alternating periods of high and low water levels significantly impact plant growth and result in unsatisfactory landscape effects. Therefore, in recent years, the focus of sponge city construction for municipal roads has been on promoting rapid rainwater infiltration, reducing sidewalk water accumulation, and improving pedestrian comfort during rainy days. The main technical measure adopted is permeable pavement for sidewalks, but there are no mandatory requirements for runoff control rates and pollutant control rates. It is difficult to cope with waterlogging caused by heavy rainfall and the impact of rainwater pollution. Soil in green belts is prone to compaction, requiring significant maintenance in the later stages. Utility Model Content

[0028] Example 1
[0029] This utility model provides a novel rainwater storage module that can be applied to the median strip of municipal roads. It can overcome the shortcomings of existing traditional rain gardens, fully implement the construction concept of sponge cities, avoid soil compaction, reduce runoff peak, reduce initial rain pollution, improve the environment, and enhance landscape benefits.
[0030] like Figure 1 As shown, the storm water storage module consists of a storm drain grate 1, an overflow well 2, a diversion channel 3, a water storage module 4, a diversion pipe 5, a slow release device 6, a flushing pipe 7, a sewage pipe 8, and an overflow drainage pipe 9, and is installed under the median strip on the side of the road. During rainfall, rainwater enters the overflow well 2 through the storm drain grate 1, flows through the diversion channel 3 and into the water storage module 4 via the diversion pipe 5. The bottom of the water storage module 4 is equipped with a delayed-release device 6. Through the diversion effect of the slow release device 6, the rainwater at the bottom with a higher concentration after sedimentation is discharged into the municipal sewage pipe through the sewage pipe 8, while the cleaner rainwater at the top flows into the overflow well 2 and then into the municipal stormwater pipe through the overflow drainage pipe 9. The flushing pipe 7 is used for cleaning the water storage module 4. The top of the water storage module 4 has a certain load-bearing capacity and can be covered with soil and planted with vegetation.
[0031] like Figure 2 As shown, rainwater storage modules are installed between roadside trees under the median strip. One set is placed between every two roadside trees, and they can be used in series when a large amount of water storage is required.
[0032] like Figure 3 As shown, a rain grate 1 is installed on the roadside flat stone to intercept larger garbage. Rainwater flows through the rain grate into the overflow well 2. A diversion channel 3 is installed on the upper part of the overflow well to guide the rainwater into the water storage module 4 through the diversion pipe 5. After the water storage module 4 is full, the excess rainwater overflows into the municipal rainwater pipe through the overflow well 2.
[0033] like Figure 4As shown, a slow-release device 6 with a time-delay adjustment function is installed at the bottom of the water storage module 4. The slow-release device 6 is used to control the rainwater stored in the storage facility to be discharged continuously, evenly, and at a constant flow rate, so as to achieve the functions of peak shaving and purification. Pollutants in the rainwater settle to the bottom of the water storage module 4 and are discharged into the municipal sewage pipe through the sewage pipe 6. The rainwater that has been settled and purified is discharged into the overflow well 2 through the slow-release device 5 and then into the municipal rainwater pipe through the overflow drainage pipe 9.
[0034] like Figure 5 As shown, the flushing pipe 7 includes a flushing section located at the bottom of the water storage module 4 and an inlet pipe connecting to the ground. After the rainwater storage module has been operating for a period of time, the bottom sludge inside the storage module can be flushed through the flushing pipe 7.
[0035] The rainwater storage module proposed in this invention can be installed in the median strip of roads. It is simple, reliable, flexible in size, and easy to install. Its water storage space reaches more than 90% of the module volume, providing a larger water storage capacity than traditional rain gardens. Furthermore, the top planting soil does not require sand mixing, preventing soil compaction and promoting plant growth. The modular and assembled installation method shortens the construction cycle and ensures construction quality. The slow-release device effectively controls the flow rate, ensuring timely sewage discharge, enhanced delayed discharge, and peak shaving functions.
[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
