Grondtransport uit ontgravingsruimte tunnelboormachine. Toepassing en
modellering van de schroeftransporteur.
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.
