Shield Tunneling Machine
Shield tunneling machines are used in the construction of large municipal tunnels (sewage, water supply, power cable pipes, communication cable pipes, natural gas pipes, etc.).Usually for concrete pipes or steel pipes, fit for construction under complex geological conditions such as pebbles, gravel and rocks. They are suitable for straight or curved tunneling distances of no less than 3000m. Using slurry balance or earth pressure balance method to complete soil cutting, rock fragmentation, tunneling, continuous slag discharge and other operations, can achieve safe, efficient, and high-quality trenchless laying of municipal large tunnels, with controllable construction risks and good control of ground settlement.
