The Yangzhou Dilong 9800 × 6300 rectangular pipe jacking machine has been successfully applied to the Shanghai Cross Tongchuan Road H-shaped underground vehicular passage project and officially put into on-site jacking construction. Featuring super-large section construction capacity, robust overall structural performance and refined attitude control advantages, the equipment precisely meets the construction standards for large-scale underground vehicular passage development in urban core areas. It steadily advances project implementation and completes phased jacking construction tasks with high standards, fully demonstrating the solid strength of our super-large rectangular pipe jacking equipment in key urban underground transportation projects.
The Shanghai Cross Tongchuan Road H-shaped underground vehicular passage is a key three-dimensional transportation infrastructure project in the local area and a core livelihood initiative for improving the regional underground traffic network, diverting ground vehicle flow and connecting surrounding land parcels. It is of great significance for optimizing the urban traffic pattern, enhancing regional traffic efficiency and empowering the development of local business circles. Adopting a unique H-shaped layout, the project involves the construction of super-large section underground vehicular tunnels. Located in the urban core, the construction site is surrounded by heavy road traffic, intricate underground pipelines and densely distributed buildings and structures. Super-large section tunnel jacking features high construction difficulty and stringent precision requirements, imposing extremely rigorous standards on the pipe jacking equipment’s structural strength, section forming capacity, tunnelling stability and settlement control performance. It stands as a highly representative high-difficulty and high-standard urban underground engineering project.
To meet the super-large-section and high-precision construction requirements of the Shanghai H-shaped underground vehicular passage, the Yangzhou Dilong 9800 × 6300 rectangular pipe jacking machine delivers exceptional working condition adaptability. Specially developed and designed for super-large section underground tunnel construction, the equipment features high structural rigidity and strong load-bearing capacity, perfectly matching the section construction demands of large-scale vehicular passages. Equipped with a high-precision intelligent attitude control system, the machine dynamically adapts to complex urban construction environments and adjusts tunnelling parameters in real time. It effectively avoids common construction risks during super-large section jacking, including axis deviation, stratum disturbance and forming errors, accurately controls tunnel alignment and construction quality, and fully complies with the refined construction standards of high-end municipal transportation projects in Shanghai.
Throughout the construction process, the Yangzhou Dilong 9800 × 6300 rectangular pipe jacking machine operated smoothly with sufficient power and continuous, efficient tunnelling performance, perfectly adapting to the special layout and super-large-section working conditions of the H-shaped underground passage. With controllable tunnelling attitude, effective settlement control and regular tunnel forming throughout the construction, the equipment successfully overcame the technical challenges of urban large-section jacking. It completed the tunnel construction task safely, efficiently and with superior quality, fully highlighting the core technical advantages of our super-large section rectangular pipe jacking equipment in large-scale underground transportation infrastructure development.
The smooth progress of the Shanghai Cross Tongchuan Road H-shaped underground vehicular passage project fully verifies the outstanding performance and reliable stability of the 9800 × 6300 super-large section rectangular pipe jacking machine in high-standard and super-large-section tunnelling for large-scale urban underground transportation projects. It further expands the application cases of our super-large section rectangular pipe jacking equipment in key infrastructure projects of first-tier cities and accumulates valuable practical experience for the trenchless construction of large-scale underground vehicular passages and complex structural tunnels in urban core areas nationwide. The project continuously supports the high-quality upgrading and development of urban three-dimensional transportation infrastructure.
