Designing of screw conveyor for EPB pipe-jacking tunneling machine
There are mainly two kinds of roadheader: Tunnelling Boom Machine(TBM) and partial-size tunneling machine.
As support and liner against cross section rock, spraying-concrete has enormous influence on the tunneling progress and the safety of the TBM tunnel's tunneling machine.
The article introduces the overall design of integrate simulating experimental platform of large-sized sunk shield tunneling machine.
Results show that this method judges the thrust system effectively and is dependable basis for drive distribution control when shield tunneling machine thrust in heterogeneous soil.
