china pipe jacking machine vs tunnel boring machine
The China pipe jacking machine and tunnel boring machine are both innovative solutions for underground construction. The pipe jacking machine is designed to install pipes underground without the need for extensive excavation. It operates by thrusting precast pipes through the ground, guided by a jacking system. On the other hand, the tunnel boring machine (TBM) is a large, complex machine used to bore through rock and soil to create tunnels with a circular cross-section. Key functions of these machines include excavation, spoil removal, and support installation. Technological features of the pipe jacking machine include its compact design and flexible operation, while the TBM boasts advanced features like laser guidance systems and automatic segmental lining. These machines find applications in various sectors, including infrastructure development, urban utility networks, and subway systems.
