Yangzhou Dilong 1000 × 1000 rectangular tube curtain machine has been successfully applied to the Entrance/Exit 1, Wuding Road Station, Shanghai Rail Transit Line 14, accomplishing on-site equipment deployment and tube curtain construction works. As China's first U-BIT Bundle Tube Curtain Project, this project adopts an innovative construction process with extremely high technical standards. Supported by stable and reliable overall performance and professional adaptability for rectangular jacking, the machine successfully completes the highly challenging tube curtain construction tasks, fully demonstrating our company’s leading technical advantages in rectangular pipe jacking and innovative tube curtain construction.
Entrance/Exit 1, Wuding Road Station, Shanghai Rail Transit Line 14 is a key supporting infrastructure project for rail transit located in the urban core area. The project adopts China's pioneering U-BIT Bundle Tube Curtain construction technology. Compared with conventional construction methods, this innovative process demands high structural precision, tight splicing of tube curtain segments and strict synchronization of jacking operations. Situated in the central urban area, the project site is surrounded by dense underground pipelines and heavy road traffic, forming a highly sensitive construction environment. Extremely high standards are required for the rectangular tube curtain machine in terms of jacking accuracy, attitude stability, overall adaptability and refined construction capacity. The project ranks among the top in the industry in terms of technical difficulty and process innovation.
To adapt to the innovative construction technology of China's first U-BIT Bundle Tube Curtain and rigorous rail transit construction conditions, our 1000 × 1000 rectangular tube curtain machine delivers outstanding process adaptability. Specially optimized for rectangular-section tube curtain construction, the machine features a reasonable structural layout and stable jacking output, which can precisely meet the assembly requirements of the U-BIT Bundle Tube Curtain. With excellent attitude adjustment performance and forming accuracy, it effectively ensures the straightness of single pipe jacking and sealing performance of multi-pipe assemblies. The machine fully complies with the construction principles and high-precision technical specifications of the innovative bundle tube curtain, and effectively avoids construction risks such as ground disturbance and alignment deviation in sensitive urban construction environments.
Throughout the construction process, the Yangzhou Dilong 1000 × 1000 rectangular tube curtain machine operated stably with precise jacking and strong adaptability to working conditions, perfectly matching the construction technology of China's first U-BIT Bundle Tube Curtain Project. It efficiently and orderly completed jacking operations for each section of the rectangular tube curtain. The tube curtain features regular shape and high splicing precision, and the whole construction process remained safe and controllable. The machine fulfilled the high-difficulty construction task for the rail transit entrance and exit to high standards, fully showing the robust strength of our rectangular tube curtain equipment to adapt to innovative new technologies.
The successful application in this key Shanghai rail transit project fully verifies the excellent performance of Yangzhou Dilong rectangular tube curtain machines for high-precision innovative tube curtain projects in urban core areas, realizing the construction case of China's first U-BIT Bundle Tube Curtain Project. It not only fills the application gap of domestically manufactured rectangular tube curtain equipment for the innovative bundle tube curtain technology, but also accumulates valuable practical experience for high-precision tube curtain construction at complex rail transit nodes and confined urban spaces nationwide. It continuously facilitates high-quality and innovative development of underground engineering for urban rail transit.
