Abstract
7 Moon 30 On that day, as the cutterhead slowly rotated, the ultra-large-diameter tunnel boring machine “Barangaru,” developed by China Railway Equipment, was launched in Zhengzhou National... TBM The industrialization center has been successfully rolled off the production line. This equipment is aligned with this year’s... 4 The “Pattigaran,” which recently rolled off the production line, is a pair of “sister” tunnel boring machines that will jointly serve the Western Harbour Project in Sydney, Australia. Leaders including Zhuo Xingjian, General Manager of China Railway Equipment, and Jia Yaowei, Deputy General Manager, along with representatives from the contractor of the Western Harbour Project in Sydney, Australia, attended the roll-off ceremony.

The cross-sea tunnel design for the Western Harbour Project in Sydney, Australia, is a dual-tube, two-way highway tunnel that connects Sydney’s WestConnex Highway network and Warrangah Once completed, the highway will become the second road tunnel under Sydney Harbour. The tunnel as a whole is shaped like “ S The shape winds its way forward, with the maximum burial depth below sea level. 52 Meter, with a minimum turning radius of 960 Meters. The strata traversed are complex and diverse, encompassing sandstone, siltstone, silt-sand layers, and silty clay layers; the uniaxial compressive strength of the rock formations can reach... 30 Megapascals; locally, the maximum can even reach 80 Megapascal—construction is extremely challenging.

In response to the project’s unique geological conditions and customer requirements, China Railway Equipment has meticulously designed and developed... The “Pati Garang” and “Balangaru” tunnel boring machines have exactly the same “physique” and “skills”: their excavation diameter is... 15.7 Rice, overall machine length approximately 113 The machine integrates multiple intelligent technologies, comprehensively enhancing equipment construction efficiency as well as the level of intelligence and automation.

The successful rollout of the “Balangaru” tunnel boring machine follows this year’s... 4 Following the “Patinglang” machine, this is the second piece of equipment delivered by China Railway Equipment for the Western Port Project. In recent years, as China Railway Equipment has actively embraced the global trend of “going global,” it has precisely aligned itself with the needs of customers worldwide, upgrading its products to be more high-end, smarter, and greener. As a result, its international “circle of friends” continues to expand! To date, tunnel boring machines of various types have been exported to markets around the globe. 30 Multiple countries and regions provide high-quality engineering equipment and end-to-end after-sales services to support global infrastructure connectivity.
