What is TBM construction?

Tunneling machine construction method refers to the construction method of tunneling with boring machine. Tunnel boring machine (TBM) construction has the advantages of rapidity, high efficiency, safety and reliability, good construction quality and low cost.

It integrates mechanical, electronic, hydraulic, laser, control and other technologies, and realizes a high degree of mechanization and automation. As the most advanced complete set of equipment for excavation and lining of large underground tunnels, it has been widely used.

Main components of TBM equipment

TBM consists of host computer and background support system. The main engine consists of cutter head, cutter head, main motor, transmission system, segment installation equipment, advanced drilling equipment, operation room and advanced support equipment.

The rear support system consists of transportation system, support system, hydraulic and control system, ventilation and dust removal system, power supply system, drainage system, complete machine and light guide system (ZED system).
