Content Validity:Hook: Iron Construction Heavy Industry has just introduced a ""shape-shifting"" underground giant, a variable diameter tunnel boring machine. Key Points: 1. On August 25th, Iron Construction Heavy Industry unveiled its variable diameter mud balance pipe jacking machine, which is destined for a rainwater regulation project in Dubai. This machine can switch between excavation diameters of 3.68 meters and 4.28 meters without disassembling the main unit, with the possibility of future expansion to 5 meters. 2. The company's variable diameter technology now covers TBMs, shields, shafts, and pipe jacking, improving efficiency and equipment utilization. 3. A standout is the ""Tianyue"" machine, which in June 2023, successfully expanded its diameter from 6.53 meters to 8.03 meters in a challenging project at the Pingjiang Pumped Storage Power Station, overcoming technical challenges like a 50-degree slope and a tight R50 radius turn. Conclusion: With over 30 patents in variable diameter technology, Iron Construction Heavy Industry is at the forefront of underground engineering solutions, providing customized and efficient answers to complex construction challenges.
