3 Terms and Definitions
GB/T 34354-2017, GB/T 41053-2021 and GB/T 35020-2018 and the following terms and definitions apply in this document.
3.1 Full face tunnel boring machine
It is a special mechanical equipment with a peripheral shell to realize the full-section formation of the tunnel through excavation and push forward. Mainly include shield machine, Rock tunnel boring machine, pipe jacking machine, etc. [Source: GB/T 34354-2017, 2.1]
3.2 Earth pressure balance shield machine; EPB
A shield machine that uses slag as the main medium to balance the formation pressure of the tunnel excavation surface and discharges slag through a screw conveyor. [Source: GB/T 34354-2017, 2.8, with modifications]
3.3 Slurry balanced shield tunnel boring machine
A shield machine that uses mud as the main medium to balance the formation pressure on the excavation surface of the tunnel and discharges slag through the mud conveying system.
3.4 Open type hard rock tunnel boring machine
In the rock with better stability, the support shoe is used to support the tunnel wall to withstand the driving reaction force and torque, and the rock tunnel excavation without segment support into the machine. [Source: GB/T 34354-2017, 2.14, with modifications]
