    摘要： The roof of a tunnel being bored by a tunneling machine is continuously supported, using sections of lagging and ring beams. A shield is positioned over the earth boring machine. The shield includes a multiplicity of elongated members. The elongated members provide elongated recesses that will accommodate sections of lagging. A length of tunnel is bored, and a ring beam is implanted in the tunnel beneath the shield. The lagging may be manipulated in the elongated recesses in the shield and positioned proximate the roof of the tunnel supported by the ring beam. Additional lagging is provided by repeating the steps.

    摘要： A shiftable support for use in tunnels, mines and the like. A plurality of longitudinally arrayed supporting frames is connected by connecting means, which connects at least alternate ones of the frames to form them into units. Displacing means displaces the supporting frames individually or the units with reference to one another, between a supporting position and a shifting position in which the respective frames or units are advanced in forward direction. Operating means decreases the dimensions of the frames in a plane transverse to the direction of advancement preparatory to displacement to the shifting position, and increases the dimensions upon displacement from the shifting position to the support position.

    摘要： The present invention relates to a tunneling method, and particularly, to a tunneling method by installing an internal pre-support member and a corresponding post support member in an alternate manner or by installing an external pre-support member and a corresponding post support member in an alternate manner, and an apparatus, respectively, therefor. The tunneling method includes: excavating a pilot tunnel in a main tunnel to be constructed; radially forming a drilled hole from an excavation surface of the pilot tunnel to a tip end of the pre-support member of the main tunnel at a plurality of locations in the pilot tunnel to install the pre-support member; inserting the pre-support member into the drilled hole, and conducting grouting and performing curing to fix the pre-support member; excavating the tunnel in stages in a longitudinal direction along an excavation line of the main tunnel and primarily spraying shotcrete to an excavation surface of the main tunnel in the main tunnel; installing a post-support member between a plurality of the pre-support members on the main tunnel surface to which the shotcrete is primarily sprayed; and connecting the pre-support member and the post-support member with a plate type support member.

    摘要： A shoring box system (10) for use in a ground trench (60) includes a pair of shoring panels (12) and a number of elongate props (22). The props are attached to the two shoring panels to maintain the panels in an erected position in which they are spaced apart, with an open zone (19) between the panels. The props can be detached from the shoring panels while the shoring panels are in the erected position. In an embodiment each panel is hollow and has a lower opening (36) with a closure flap (38) for closing the opening, to enable filling material in the hollow to pour from the panel as it is removed from the trench. Also in an embodiment, each shoring panel is tapered in a downward direction.

    摘要： A rib expander, for use with tunnelling apparatus, in which a plurality of arcuate segmental members form a ring, at least two of the members being separable longitudinally to expand the ring. The ring is mounted to provide pivotal movement about a vertical circumferential axis of the ring as well as transverse movement in the plane of the ring and movement along the normal axis of the ring.
