Abstract
Abstract An apparatus for driving a tunnel shaft includes a driving machine which is supported within an auxiliary shaft which is pivotally mounted on a wheeled track car in a position such that it may be raised to the desired drilling or angle by an associated positioning mechanism. The drilling machine is mounted within the auxiliary shaft in a tubular support which may be clamped in position in respect to the auxiliary shaft or when the drilling progresses clamped to the drilled tunnel shaft walls. The drilling tool is mounted in front of the driving motor in a manner such that it can be extended or retracted as desired. An advancing stroke mechanism carried on a frame supporting the auxiliary shaft is arranged to engage a tubular structure supporting the driving motor and advance it outwardly into the wall structure being drilled. The advanced tubular support structure is supported in its extended position by additionally supplied cylindrical supporting and carrying elements which are placed between it and the mounting base therefor on the under carriage as the tunnel is progressively formed. The structure is locked in each incremental advance position by transversely movable hydraulic wedge elements which are positioned behind support cams defined on the previously applied supporting structures until another support structure of a length equivalent to the advance is added behind them. A tunnel shaft is drilled from the bottom to the top by first forming a cavern at the bottom of the intended shaft and moving the drilling apparatus into position within the cavern. Thereafter the auxiliary tunnel shaft is raised to an elevation corresponding to the angle at which the tunnel is to be driven and the drilling tool is extended to form an initial drilling cut while its driving motor is supported within a tubular member located within the auxiliary shaft. After an initial cut is made the drilling member together with its driving motor is advanced outwardly and clamped against the wall of the tunnel which has been drilled at the exterior of the auxiliary shaft.
