摘要： Driving shield machines are known in the construction of tunnels through unconsolidated rock; in these known machines, the working face is shored up by supporting fluid in a working chamber of the driving shield machine sealed off from the tunnel. With these known driving shield machines, unconsolidated rock can fall out of control into the entire working chamber if the working face collapses during the tunnelling process and thus seriously jeopardize the safety of men working in the tunnel. To reduce this risk considerably, the driving shield machine according to the invention is provided with a partition (40) which can slide longitudinally and divides the working chamber (3) into two partial chambers (3', 3''). An aperture (52) is provided in the partition (40) and a tunnelling arm (10) extends through the aperture, which is designed so as not to restrict the mobility of the tunnelling arm (10). Since the partition can slide into a position adjacent to the working face, the latter can be given additional mechanical support if a collapse seems likely, without any need to interrupt the tunnelling process and provide support using the support fluid.

摘要： The invention relates to a device for digging roads, tunnels or the like, said device comprising a boring head that can be rotationally driven about a rotational axis (D) and displaced in the digging direction. According to the invention, the boring head (100) comprises an inner part (1) which is driven about the rotational axis (D) and an outer part (6) which is also driven about the rotational axis (D), concentrically to the inner part (1).

摘要： The invention relates to an advancing device for boring sections of roadway, tunnels or similar, with a working head (100) comprising first rotary cutters which are distributed over the surface that faces the working face (O), within the outer periphery of said working head and which are designed to loosen the solid material on the working face (O); and second rotary cutters (2) which protrude beyond the outer periphery to advance an overcut. According to a first embodiment of the device, the second rotary cutters (2) have a greater outer diameter than the first rotary cutters (1). According to a second embodiment, the fixing devices for the second rotary cutters comprise elements which allow said second rotary cutters to be mounted optionally in positions projecting radially to different distances beyond the outer periphery of the working head.

摘要： The invention relates to a tunnel-boring machine (100) for driving a tunnel bore optionally in open or shielded mode. The inventive tunnel-boring machine comprises a shield tail (33), said shield tail being connected to a bore head (10) and optionally covering the bore walling over a set length, a bracing device which can optionally be fixed in the tunnel bore, an advancement device (25) which can be operated optionally, said advancement device resting on said bracing device (25) and acting on the bore head (10), and a device for generating power (35) which has a variable length, rests on a tubbing (32) and acts on the bore head (10) and which can also be operated optionally. An inner kelly (16) is provided for introducing the driving forces into the bore head (10) during open mode, said kelly being moveable in the direction of boring in relation to the bracing device (20). The advancement device (25) is linked to the kelly and the bore head (10) is supported at the working end of said kelly.
