摘要： Apparatus for use in driving tunnels and having an advanceable shield formed by a plurality of elongate members disposed sideby-side in contact with the wall of the tunnel. The members are supported by two frames interconnected through piston and cylinder units. Each elongate member has sets of apertures with guide members therein defining guide surfaces which selectively receive spring-loaded slidable pins carried by the frames and respectively allocated to the members. The pins carried by one frame each have inclined surfaces at its outer end which engage on inclined guide surfaces in each associated aperture to permit the pin to retract automatically upon relative movement between the frame and the member having the aperture in question along the axis of the tunnel. The pins carried by the other frame are each manually rotatable about its axis through 180* to bring an abutment surface at its outer end into engagement with one of two opposite surfaces in an associated aperture extending parallel to the axis of the pin whereby the pin can selectively lock the frame to the member having the aperture in one or the other direction along the axis of the tunnel. Those pins carried by the other frame also each have an inclined surface engaging on one of two converging inclined surfaces in the associated aperture so that the pin can be retracted automatically when relative movement occurs between the frame and the member having the aperture in one direction or the other.

摘要： An advanceable shield for a tunnel driving apparatus which is composed of a series of elongate members arranged side-by-side and supported on relatively movable frames to define an internal excavating space. The members are selectively connectible with the frames and can be advanced by relative displacement between the frames. Some of the members, preferably over the floor region of the shield, are each of multi-part construction with a main elongate hollow body and a U-shaped hollow component pivotably connected thereto and receivable therein. Means, such as a piston and cylinder unit is provided to move the component in relation to main body so as to expand or contract a dimension at the rear end of the member to thereby permit the member to tilt about an axis extending transversally of the longitudinal axis of the tunnel. In this way control of the direction of advancement of the tunnel can be effected.

摘要： A tunneling shield comprises pairs of forward and rearward support frames carrying sharp ended planks, the frames being supported on shoes slidable along abutments. Each frame is constructed in two sections which are pivoted together about an axis extending longitudinally of the shield. The lower ends of the sections of each pair are interconnected by an extensible strut or cross-brace.
