Recently, Shanghai’s first integrated pump and gate project was successfully commissioned and put into operation in the Songjiang South Station large residential community in Songjiang District. This project, stretching from Dongjing Port in the west to Songwei North Road in the east, includes the construction of a new integrated pump and gate at Gaojiashe West and the opening of a 361-meter-long channel in the Gaojiashe River. It aims to improve the water conservancy infrastructure system of the Sanchangwei area and significantly enhance the region’s flood control and drainage capabilities.
This marks a significant milestone in Shanghai’s water conservancy projects, moving from the traditional separate construction of pumps and gates to integration, intelligence, and intensive management. It also represents the first successful application of Kaiquan’s integrated pump and gate products in a core area of a megacity.
Innovative Breakthrough: Pump and Gate Integration, “Unleashing” the City’s Resources
In traditional water conservancy projects, pump stations and gate stations are separate, resulting in large land areas, long construction periods, numerous equipment interfaces, and complex operation and maintenance. In Shanghai, where land is extremely valuable, especially in densely populated built-up areas and large residential communities, space and construction time are rigid constraints.
The innovation of Kaiquan’s integrated pump gate lies in combining the pump station and gate station into one:
Pump Gate Type: One gate with two pumps
Pump Model: 800ZQZ-160-90 submersible axial flow gate pump, single pump flow rate 2m³/s, total flow rate up to 4m³/s
Working Gate: Exposed flat steel gate, B×H×W=6.6×4.6 (m)
This design is not a simple functional addition, but a holistic optimization starting from the ground up. All components of the integrated pump gate—including the gate pump, gate, opening and closing system, and control system—are designed as an integrated device, both holistically and locally.
The Kaiquan team used structural mechanics software CAE and computer fluid dynamics simulation software CFD for structural and flow optimization design and verification. Based on this, and through continuous testing and iteration in hundreds of projects, the product’s reliability is ensured to withstand various complex working conditions.
Immediate Results:
✅ Smaller Footprint: Saves approximately 50% of land compared to traditional pumping stations, making it suitable for space-constrained environments such as urban core areas and residential communities;
✅ Shorter Construction Period: Significantly reduced land area leads to less civil engineering work, significantly shortening the overall construction cycle and minimizing impact on surrounding traffic and residents;
✅ Simplified Operation and Maintenance: Integrated design reduces equipment interfaces and potential failure points, while intelligent monitoring enables remote scheduling and unmanned operation.
Intelligent Core: Cloud Platform Empowerment Enables Pumping Stations to “Think”
If the integrated pumping station represents an innovation in “form,” then Kaiquan’s independently developed control system is the injection of “soul.”
The Gaojiashe West integrated pumping station is equipped with Kaiquan’s dedicated control system, which can monitor pump operation in real time, collect and record operational data, and upload it to the central control intelligent cloud platform. More importantly, it enables real-time monitoring and alarms via mobile phone SMS through the internet—regardless of the location of management personnel, the pumping station’s operational status is always under control.
Intelligent Switching of Operation Modes:
Gravity Drainage Mode: When the inland river water level rises to the warning level and the outer river water level is lower than the warning level, the system automatically opens the gates, allowing the inland river water to flow into the outer river by gravity.
Forced Drainage Mode: When the inland river water level rises to the warning level and the outer river water level is higher than the inland river water level, the system automatically starts the gate pumps for forced drainage until the water level drops to a safe level, at which point the pumps are shut off.
This closed loop of “perception-decision-execution” transforms the pump gate from a passive response to an active scheduling mechanism, equipping urban flood control and drainage with a smart brain.
Implementing Significance: From “First Case” to “Paradigm”
The completion and commissioning of the Gaojiashe West Integrated Pump Gate not only improves the water conservancy facilities in the Songjiang South Station area but also carries multiple demonstration values:
✅ Feasibility Verification of the Technical Route: As the first integrated pump gate project in Shanghai, this project successfully verified the engineering adaptability of this technology in soft soil geology and high-density built-up areas. This provides the first practical example for citywide implementation, marking a new stage in Shanghai’s water conservancy projects, moving from the traditional “separate pump and sluice construction” to integration and intelligence.
✅ Demonstrates the technological maturity of local equipment: This signifies the maturity of Shanghai-based companies, represented by Kaiquan, in the field of integrated pump and sluice technology and products, moving from participating in the drafting of national standards to large-scale engineering applications. It provides efficient, economical, and intelligent new solutions for Shanghai’s river management, flood control and drainage, and water environment improvement during the 15th Five-Year Plan period.
✅ Substantial improvement in urban governance capabilities: It improves the water conservancy system in the Songjiang South Station area, enhances flood control and drainage capabilities and water resource allocation, supporting regional urbanization and high-quality development. Technological innovation addresses pain points such as urban flooding, water system circulation, and water quality improvement, providing strong support for the construction of resilient cities and ecologically livable environments.
From the intensive innovation of integrated pump and sluice systems to the precise scheduling of intelligent control, from Shanghai’s first case at Songjiang South Station to future applications in more cities—Kaiquan consistently responds to the core demands of urban development for water security through technological innovation.
Kaiquan, intelligently managing water resources, safeguarding the resilient future of every city.
