en.Wedoany.com Reported - Today (June 3), the construction of the Pinglu Canal, a key project of the New International Land-Sea Trade Corridor in western China, will reach a major milestone: the Madou and Qishi hubs, two of the three major shipping hubs under control, will begin water filling. The Pinglu Canal will achieve full water flow, entering the water commissioning phase comprehensively, laying a solid foundation for its scheduled opening to navigation in September.
The water source for filling the Madou Hub comes from the main stream of the Xijiang River upstream of the hub and the natural runoff of the Jiuzhou River downstream. The engineering team has adopted a plan of "breaching the cofferdam first, then filling with water, and commissioning the left and right lock chambers sequentially." Construction workers first breach the downstream cofferdam, allowing water to slowly fill the downstream lock chamber through the breach. Once the water level meets the standard, water commissioning begins. Subsequently, the upstream and left and right lock chambers will be filled and commissioned in sequence, with the entire process expected to last 30 days.
The water source for filling the Qishi Hub is mainly divided into two parts: the natural runoff of the Jiuzhou River upstream of the hub and the water from the main stream of the Xijiang River diverted through the Yin-Yu-Ru-Qin project. To prevent issues such as water impact and sediment deposition caused by a one-time cofferdam breach, and to synchronize the sealing work of gates and valves with water commissioning, the engineering team has adopted a plan of "filling water through downstream buried pipes, and commissioning the left and right lock chambers sequentially," advancing the water filling and commissioning in stages. The water filling operation is divided into three phases. After each phase reaches the planned water level, the corresponding gates and valves will be commissioned, with the left and right lock chambers tested sequentially. Ultimately, the Qishi Hub will be filled to a water level of 8.7 meters, matching the downstream water level. The entire process is expected to last 26 days.
To ensure the safe and orderly progress of the water filling operation, the Pinglu Canal construction management team has conducted multiple rounds of precise calculations of the upstream and downstream water level elevations during the early construction phase. During the operation, dedicated personnel are assigned to monitor water level changes in real time throughout the process, strictly controlling all operational parameters.
Next, the Pinglu Canal construction management team will follow the procedure of "single-unit commissioning, system integration testing, and real-ship trial navigation" step by step. They will conduct comprehensive testing and commissioning of all equipment systems, including gate opening and closing, water conveyance control, electrical systems, and safety monitoring, optimizing operational parameters to ensure all equipment meets navigation operation standards.
