On May 28, following several consecutive blasts, the last section of the central rock bar at the Jiuzhou River section of the downstream channel of Qishi Hub on the Pinglu Canal was detonated. The completion of excavation of this rock bar marks the full completion of the main excavation work of the Pinglu Canal waterway.

The waterway project of the Pinglu Canal has a total length of 125.5 kilometers, with a total earth and rock excavation volume of approximately 214 million cubic meters. The geological conditions along the canal are complex, with a long flood season and large volumes of water, significantly affecting construction flood control and diversion. These challenges are compounded by the simultaneous progress of multiple projects such as bridge construction and pipeline relocation, leading to frequent cross-operations among multiple specialties, work types, and equipment, with evident mutual interference and constraints. This places extremely high demands on construction coordination and on-site control capabilities, making the overall construction difficult and challenging.

The construction management team of the Pinglu Canal coordinated the overall construction diversion timelines across the entire line, effectively mitigating cross-construction interference among different sections. They strengthened hydrological and meteorological monitoring and early warning, established a multi-department coordinated flood prevention mechanism, and built a solid safety line. Throughout the construction phase, they consistently adhered to the principle of prioritizing ecology, efficiently advancing the comprehensive utilization of earth and rock materials, promoting green ecological bank protection techniques, and creating demonstration sites for ecological conservation areas using sections of the canal where the channel was straightened by cutting off bends.
