Application Case—— Yankaba Pump Station
Project Overview >>>
The Yanca Pump Station is located in the urban area of Jingzhou City, tasked with drainage operations to remove excess rainwater from the city and discharge it into the lower section of the Yangtze River's Shashi River Bend. Situated in a subtropical monsoon humid zone characterized by simultaneous rainfall and heat, the region features distinct seasons, abundant rainfall, ample sunlight, and a mild climate with a long frost-free period—conditions ideal for growing crops such as grains, cotton, and oilseeds, making it highly favorable for agricultural development. Over the years, the average annual precipitation has been 1,079.7 mm, with 79.2% of this total occurring between April and October. Meanwhile, the average annual evaporation rate stands at 1,285.5 mm, while the frost-free period lasts for 255 days annually, maintaining an average relative humidity of 80%. The drainage standards are set as follows: for the Shashi District, Baolian District, and Shashi Farm District, the goal is to clear out 24-hour rainfall events—occurring once every 20 years—within 24 hours; for the Cenhe District, the target is to drain 24-hour rainfall events—occurring once every 10 years—within 24 hours, ensuring no standing water remains on field surfaces; and for the Luochang District, the aim is to manage one-day heavy rainfall events—occurring once every 10 years—by draining the water within three days, down to a depth that allows crops to withstand temporary submersion. On the outer river side, the flood protection standard matches that of the main embankments along the Jingjiang River. The pump station is designed to handle a maximum flow rate of 55 cubic meters per second, equipped with six mixed-flow pumps, each driven by a 1,800-kW electric motor unit installed inside the pump house.
The Yan Ka Pump Station adopts a post-dike layout. The station's main structures include the main pump house, installation bay, auxiliary powerhouse, substation, trash rack bridge, forebay, intake channel, outlet box culvert, and discharge channel, among others. The project is classified as a Class II Large (2) project, with the floodgate and dike-penetrating structures designated as Grade 1, while all other major structures are rated as Grade 2, and secondary structures fall under Grade 3.

Application Case—— Jiepai Hub
Project Overview >>>
The Jiepai Water Control Hub consists of a ship lock, regulating gates, a pumping station, and the Puhe Regulating Gate. The Jiepai Hub Pumping Station is a bidirectional pump station designed to handle a flow rate of 300 m³/s, equipped with nine sets of X-type, bidirectional-flow, open-type, hydraulically fully adjustable vertical axial-flow pumps, each capable of handling a single-unit design flow of 33.4 m³/s. These pumps are paired with 2,000-kW vertical synchronous motors rated at 10 kV. The regulating gates feature a total of five openings, each 16 meters wide, resulting in an overall clear width of 80 meters, with maximum intake and discharge capacities reaching 745 m³/s. Meanwhile, the ship lock is classified as a Class VI structure, with a chamber length of 180 meters, a chamber and portal width of 16 meters, and a threshold water depth of 3.0 meters. It is designed to accommodate 100-ton cargo vessels, with a verified capacity for 300-ton cargo ships. Additionally, the Puhe Gate, located on the northern side of the Puhe River approximately 500 meters upstream from the Jiepai Hub, serves as a key control structure within the river system’s water management scheme, featuring a clear width of 18 meters across its three openings.
