Literature survey, Report 97.3.TT.4865, Transport Engineering and Logistics.

In modern tunnel engineering more and more tunnel boring machines (TBM's) are used, Two types of TBM's are used: Slurry balanced shield (Slurry shield) and Earth Pressure Balanced shield (EPB shield). In TBM's with EPB-shield often a screw conveyor is used for transportation of soil out of the work chamber.

In chapter 1 the backgrounds of several tunneling systems are described. Then chapter 2 gives the demands for the possible transport facilities. After that in chapter 3 the backgrounds of usage of a screw conveyor in a TBM with EBP-shield are discussed. At last chapter 4 describes a (new) analytical model for a screw conveyor in circumstances as in a TBM.

It was necessary to make an new analytical model, because in the no analytical model is available describing the transport of material in a screw conveyor with an angle of inclination.
