40 Sany rotary drilling rigs fought day and night, and 16,000 pile foundations supported the "underground backbone" of Nanjing North Railway Station

The Yangtze River is surging, and Zhongshan is majestic. At Nanjing North Railway Station, a super hub site that carries the core mission of the Yangtze River Delta "metropolitan area on rails", a chapter of the project on deep foundation and speed is being staged. Nearly 40 sets of SanyRotary drilling rigsThe steel giant array formed roared endlessly, 16,000 deep piles pierced the rock formation, and Sany pile machine took on the role of "the important weapon of the country" to pour a solid foundation for this future hub.

As the largest hub passenger station of China's "eight vertical and eight horizontal" high-speed railway network along the North Yangtze River, Nanjing North Railway Station guards the golden cross intersection of the Yangtze River Corridor and the Guangdong-Haihai Corridor. With a total construction area of 692,100 square meters and 3 sets of 30-line rail systems, the project is the only railway hub in Nanjing that integrates high-speed rail, intercity and general-speed railways, and is also a key node project of the high-speed railway along the North Yangtze River.

The Iron Array creates a super hub

"Sany Army" led the attack: at the peak of the project, more than 80 rotary drilling equipment roared day and night, of which Sany rotary drilling rigs accounted for nearly half (40), forming an absolute main lineup. Breakthrough of the extreme construction period: In the face of the completion of the pile foundation at the end of April, Sany Equipment completed the project task efficiently with high attendance.

The technical game through the strata of the Six Dynasties

In the face of the sedimentary conglomerate layer of the Yangtze River paleochannel, the "rock penetration mode" of the Sany rotary drilling rig greatly improves the drilling time of a single pile compared with the traditional equipment. At the same time, it is equipped with Sany intelligent operating system to monitor the verticality of the drill pipe and the verticality error of the hole in real time<1‰，完美满足高铁站“零容错”需求。

Cluster intelligence: Through the "Sany Yiweixun cloud platform", the operation status of 40 equipment is monitored in real time, and dozens of parameters such as fuel consumption, drilling depth, and start-up time can be visualized in the cloud, which is more convenient for the owner to manage the equipment, and the construction efficiency is greatly improved.

With the progress of pile foundation construction, the underground "bones" of Nanjing North Railway Station have been formed. The 16,000 deep piles are like a password embedded in the earth, recording the majestic power of the Sany rotary drilling rig group to penetrate the rock and soil, and also witnessing the hard core power of China's intelligent manufacturing to conquer the super project. The "orbital aircraft carrier", which is expected to be completed in 2027 and has an annual capacity of 36 million passengers, is growing from the roar of the Sany rotary drilling rig.
