What is an Earth Pressure Tunnel Boring Machine

An earth pressure tunnel boring machine (EPBTBM) is a type of underground Crusher that uses mechanical pressure at the face of the tunnel to counterbalance earth pressures. It is a form of tunnel boring machine that negates the need for compressed air to control subsidence of the tunnel face.

Earth pressure balance - Wikipedia

Earth pressure balance, or EPB, is a mechanised tunneling method in which the excavated material is used to support the tunnel face whilst it is being plasticised using foams/slurry other additives to make it transportable and impermeable. The spoil is admitted into the tunnel boring machine (TBM) via a screw conveyor (cochlea) arrangement which allows the pressure at the face of the TBM to remain balanced without the use of slurry.

Face Stability Analysis for the Earth Pressure

Earth pressure balance tunnel boring machines (EPB TBMs) were successfully used for tunnel excavation in loose grounds. Determining the minimal support pressure in the tunnel face is one of the most critical steps in tunneling by the earth pressure balance method. This study aimed to investigate the tunnel face stability of the Dez–Ghomrood water ...

Comparison of earth pressure balance and slurry

16-08-2018  Earth pressure balance (EPB) and slurry tunnel boring machines (TBM) have both been utilised for construction within the Chalk in the UK, however, there has been a general trend recently in preferential selection of slurry TBMs. This presents greater logistical considerations in terms of handling and treatment of spoil in comparison to an EPB TBM.
