Gaotang County, a historical and cultural city located in the northwest of Shandong Province, is famous for its unique cultural landscape and rich tourism resources.
However, with the accelerated urbanization process, the water system environment in Gaotang County is facing unprecedented challenges and pressures.
In order to protect the green mountains and rivers of this land and ensure the sustainable use of water resources, Gaotang County actively planned and implemented water system management and ecological improvement projects.
Guozi City Branch Canal Project
As an important river in Gaotang County, Guozi City Branch Canal carries the heavy responsibility of discharging and draining road rainwater.
However, with the expansion of the city, the original river facilities can no longer meet the growing demand for drainage.
In this context, Gaotang County decided to carry out drainage and improvement of Guozi City Branch Canal to improve its drainage capacity and ensure urban safety. Kaiquan is the undertaker of this important project.
Kaiquan Solution

At the beginning of the project, Kaiquan Jinan Branch conducted in-depth docking with the design institute and actively promoted the design concept and application advantages of the integrated pump gate.
Through sufficient exchanges and communication, Kaiquan tailored a complete solution according to the needs of customers and the design institute:
Sluice station type: integrated pump gate, with one gate and two pumps, a total of 2 project sites, 6 gates and 12 pumps, to achieve efficient drainage;
Water pump model: submersible axial flow gate pump 900ZQZ-125-185, power 185kw, excellent performance, stable and reliable;
Host type: hydraulic flip-up hoist QPPY2-500KN, fast lifting speed, stable structure, good landscape effect;
Working gate: exposed flat steel gate, precise size, strong sealing, meeting the specifications of water conservancy and hydropower projects.
Product advantages

Kaiquan integrated pump gate combines water pump and gate into one, integrating water pump, gate, opening and closing system, flap gate, sewage interception system, liquid level monitoring, maintenance system, intelligent control and other ancillary facilities into one, without occupying additional land area, without affecting the flow of river, and ecological environment friendly.
In this project, it has the following advantages:
① Gate advantage:
a. After CAE gate strength calculation, it is guaranteed that the gate strength and rigidity meet the requirements, reduce the ineffective thickness of the gate, and save equipment investment.
b. The gate sealing structure is diverse to ensure that the sealing meets the design specifications of steel gates for water conservancy and hydropower projects.
② Submersible axial flow pump advantages:
a. Use a special gate pump (submersible axial flow pump) specially designed for gate installation, and the overall optimization design for gate installation is carried out, with shorter length and lighter weight. The center of gravity of the water pump is closer to the center of gravity of the gate, and the vibration of the water pump operation has less impact on the gate. The gate pump is also equipped with leakage and temperature rise sensors to prevent hidden dangers of the gate pump underwater.
b. The motor adopts a double-support design, and the rear end of the motor is matched with the gate. At the same time, it is equipped with a rib plate to achieve multi-point support and reduce vibration.
c. Adopting a high-efficiency hydraulic model, the water pump has high efficiency.
③ Advantages of the hoist:
Hydraulic flip-up hoist has a fast lifting speed, stable structure, less part above the ground, and good landscape effect.
④ Advantages of the maintenance gate:
The stacked beam gate has a simple structure, light weight, small lifting force, and is easy to carry.
Project Achievements
With the help of Kaiquan, the drainage capacity of Laotanggonggou and Guozishi branch canal has been significantly improved.
After the implementation of the project, it not only effectively solved the flooding problem in the surrounding areas during the flood season, but also injected new vitality into the water system management and ecological improvement projects in Gaotang County.
As a leader in smart water affairs, Kaiquan will continue to drive with technological innovation and guarantee with high-quality services to contribute to the water system management and ecological improvement projects in more cities.
