On the channel slopes up to 188 meters high, intelligent measuring robots and wet spraying manipulators make construction precise and environmentally friendly; in the smart mixing plant of more than 70,000 square meters, the intelligent production management system can effectively improve production efficiency and reduce material loss; when the door of the smart command center is opened, the "Digital Twin Smart Canal" screen comes into view, showing the construction status of each section in real time...

During the construction of the Pinglu Canal, a "smart canal" is gradually taking shape through lean project management, construction equipment upgrades, process and method innovations, and digital technology empowerment.

Recently, college student reporters saw at the construction site of the Qishi hub of the Pinglu Canal that the concrete mixing plant, which consists of a mixing plant, refrigeration plant, silo, etc., is large in scale and has an intelligent management and operation system.

Bai Lulu, director of the engineering and technology department of the Pinglu Canal Qishi Hub Project of CCCC First Navigation Engineering Bureau, said that the Pinglu Canal is large in scale and construction intensity, and the quality requirements for the project are extremely high. For example, the allowable deviation of the flatness of the cast-in-place concrete water conveyance corridor is 10mm, and in the actual operation of this project, they have to work hard to control the error within 3mm.

The Qishi hub has the largest concrete mixing station in Asia, with a maximum daily production capacity of 12,000 cubic meters, equivalent to the amount needed to build a four- or five-story building.

"Since the volume of concrete required for the project is extremely large, an intelligent command system was introduced to monitor the production process and orderly dispatch transportation vehicles, which saves manpower, improves efficiency and greatly improves the accuracy of construction." Bai Lulu said that after the concrete pouring was completed, a unique automatic spray maintenance system was set up. By monitoring the temperature inside the concrete and adjusting the water temperature of the cold water pipe, it cooperates with manual inspections to provide "double insurance" for the quality of the project.
