[0002] The stormwater culvert outlet is a key node in the drainage system.

[0003] However, in actual applications, the existing rainwater culvert outlets are often overlooked by designers or managers due to their location properties at the end of the pipeline network, which makes them prone to improper design or operation and maintenance. This can lead to the discharge of highly polluted initial rainwater into the initial rain culvert during heavy rain, thereby polluting the water body.

[0004] Therefore, how to realize the functions of collecting and transporting scattered mixed sewage in the rainwater culvert, intercepting initial rainwater, discharging rainwater, utilizing and transporting river and lake water, and detecting water quantity and quality at the rainwater culvert outlet node, so as to solve the overflow of polluted water, comprehensively utilize water resources, protect the water environment, and ensure the stability of the drainage system has become a technical problem that technical personnel in this field urgently need to solve.

[0033] Beneficial effects of the present invention:

[0034] The present invention realizes the functions of collecting and transporting scattered mixed sewage in the rainwater culvert, intercepting initial rainwater, discharging rainwater, utilizing and transporting river and lake water, and detecting water quantity and quality at the rainwater culvert outlet node. It can not only solve the overflow of polluted water, but also comprehensively utilize water resources, protect the water environment, and ensure the stability of the drainage system.

[0035] This invention can achieve precise sewage interception and block the source of pollution. By combining a sunken interception pit with a sewage interception pipe, it can efficiently collect scattered mixed sewage from urban rainwater pipes during dry weather. Combined with the opening and closing control of the gate under the central partition wall and the drainage compartment gate, it can effectively prevent misconnected and mixed sewage from entering the water body, curbing water pollution at the source and reducing the probability of eutrophication, black and smelly water bodies, and other problems.

[0036] This invention enables the tiered collection and discharge of rainwater, reducing the load on water bodies. The upper and lower staggered gates of the drainage compartments work in conjunction with the primary rain culvert to treat rainfall in stages. Initially, the upper gate is closed and the lower gate is opened, directing highly polluted initial rainwater into the primary rain culvert for centralized treatment. Later, the upper gate is opened to discharge less polluted rainwater, achieving tiered purification of rainwater, significantly reducing runoff pollution and alleviating the pollution load on the receiving water body.

[0037] This invention can flexibly utilize water resources and improve their utilization rate. The irrigation pipe in the drainage chamber is connected to the water body. During the dry season, the upper lower gate can be opened as needed, and the initial rain box culvert gate can be closed to direct water from the water body into the irrigation pipe for greening irrigation, landscape water replenishment, etc., achieving flexible allocation and recycling of water resources, alleviating water pressure in cities during dry seasons, and improving the comprehensive utilization rate of water resources.

[0038] This invention can also be linked with intelligent systems to achieve intelligent monitoring and coordinated control, ensuring efficient system operation. Liquid level gauges in the inlet and outlet tanks monitor water levels in real time, and online water quality monitoring devices at the grid partition walls provide dynamic feedback of water quality data. Based on this information, all gates are controlled in a coordinated manner, enabling the system to automatically adjust its operating mode based on actual water volume and quality, accurately responding to varying rainfall conditions. This ensures efficient and coordinated operation of sewage interception, drainage, and storage, enhancing the intelligent management of the stormwater pipe network system.

[0039] The present invention can also solve the above problems to a certain extent. At the same time, the land use and construction cost of the comprehensive setting are more optimized than the separate settings of each function.
