Driving apparatus for shield driving or for pipe-jacking operations with a hydraulic conveying arrangement

摘要

The invention relates to a driving apparatus for shield driving or for pipe-jacking operations with the use of a hydraulic flush-conveying system for removing the soil/water mixture or the like located in the partitioned excavating chamber (7), a mechanical discharge conveyor (screw conveyor 15) being provided at the same time, by means of which the excavated material can likewise be discharged from the excavating chamber (7). According to the invention, a processing container (17) is provided which is loaded by the discharge conveyor (screw conveyor 15) and in which the delivered material is processed by the addition of water via a separate water feed line (19) into a pumpable mixture which can then be pumped out of the processing container (17). A vibrating screen (25) in conjunction with a stone gate (26) is expediently arranged in the processing container (17). <IMAGE>
