  • DEM-based numerical study on discharge behavior of EPB

    Compared to the study on the performance of the screw conveyor for the soil, however, the research on the performance of the screw conveyor for the rock is insufficient. Considering the domestic tunnel sites with more rock layers than soil layers, simulation of discharge of 6 types of rock chips by the screw conveyor was conducted using DEM.

  • Continuous Conveyor Design in EPB TBM Applications

    2017-04-28· belt conveyor (30" BW) was constructed behind the TBM and back-up system at the tailpiece and back-up car assembly at the last deck. The muck was dis-charged from the screw conveyor into the loading hopper of the tailpiece at the front of the tailpiece back-up car, which elevated the conveyor into the crown of the tunnel.

  • An experimental study on screw conveyor system of EPB

    Abstract. The screw conveyor system installed in EPB Shield TBM chamber was manufactured in small scale for pilot test to investigate the tunnel muck hauling system that could control the earth pressure and support face thrust force. In this experimental study, there were three different test conditions that include screw angles, screw pitch, and screw RPM.

  • location of the screw conveying for a TBM

    The TBM manufacturer has first choice on the answer. But, if everything else is equal (not likely), I like to run muck conveyers high to get them above the muck cars for discharge into the cars. Unless it is a large mole, the conveyor train will have to rise up to get over the cars; the less height, the shorter the screw conveyor.
