    Abstract: A conduit repair structure in which solid objects are less likely to accumulate on a conduit bottom and that, even if solid objects accumulate on the conduit bottom, facilitates removal of the solid objects. A hollow frame-like reinforcement body laid substantially along a cross-sectional shape of a conduit (1) is constructed using a reinforcing member (2) having fixing parts (2p) arranged at predetermined intervals on the inner side of the conduit (2). Resin inner face bars (10) are attached to the inner side of the reinforcement body, and a curable filling material is placed in the space formed by the inner face bars (10) and a conduit inner wall (1a) to form a filling material layer (3). A body section (10c) of each inner face bar (10) is formed recessed in its width direction. The recessed shape of the body sections (10c) forms riblets on the bottom of the conduit, and this reduces resistance to water flowing in the conduit.

    Abstract: A general segment 20 which is propelled and set in an excavated hole by a propulsion excavating machine, and a flexible segment where flexible members 4 and rigid ring members are alternately installed and connected inside the skin-plate 7 provided on the outer periphery side of the side rings 5 having the same thickness as the general segment and a thrust-receiving member 9 is provided inside the flexible portion, are propelled and set by the propulsion excavating machine and then secondary coating concrete 30 including a secondary watertight band 15 is applied to said side ring. As a segment for a shield tunneling method, the flexible segment appropriately provides flexibility to quickly cope with earthquakes and uneven settlement. The flexible segment may be handled in the same manner as a standard general segment during excavation work, providing excellent application potential.

  • Patent number: 5466187
    Abstract: A mine ventilation structure for installation at the intersection of first and second passageways in a mine. The ventilation structure defines a first passage communicating with the first passageway and a second passage communicating with the second passageway. The ventilation structure includes a pair of generally parallel, spaced-apart side walls defining the side walls of the first passage, and a plurality of elongate deck panels extending between the side walls and forming the roof of one of the first and second passages and the floor of the other of the first and second passages. Each deck panel is a sheet metal panel generally of inverted channel shape in transverse cross section, having an upper web and side flanges extending down from the upper web at opposite sides of the web. Tie bars hold the deck panels together in fixed side-by-side relation with the side flanges of the panels closely adjacent one another so that the webs of the panels form a substantially continuous surface.

  • Patent number: 5324139
    Abstract: A new combination of means and method steps is used in a method of constructing long tunnels with a lining, wherein excavation is effected with a tunnel boring machine (1) with a yielding shield mantle (4), building is effected continuously under the protection of the shield tail in a modular construction with tubbing stones of a special form complementing each other to form tubbing rings (15) while, until a new equilibrium of the rock formation is reached, occurring deformation forces are absorbed by the shield tail (4) and the tubbing rings which are yieldingly constructed to a limited degree, an outer seal of the tubes is provided and the gap between the excavation (2) and the tunnel tubes is filled with a material (22) which may be yielding to a limited extent to absorb long-time deformation forces. A tunnel construction made by the method, special forms of tubbing stones and new embodiments of drive means for the tunnel are disclosed.

  • Patent number: 5131789
    Abstract: A connector assembly for use in fastening two plate members together, particularly such members may be mill hole liner ring segments or mill hole liner rings which are fastened together to form a mill hole chute. The connector assembly is comprised of a connector tongue, connector clip and a wedge means. The connector clip is attached to a first plate member and extends outward perpendicularly from said plate member. The connector tongue is attached to a second plate member. In use the two plate members are aligned in edge to edge abutment so that the connector tongue is inserted through the aperture in the connector clip. A wedge means is then inserted through the aperture in the connector tongue. The wedge means is held in place by frictional forces between the wedge, the connector tongue and the connector clip. The wedge means is driven into the aperture causing the plate members to be connected and positioned in edge to edge alignment.

  • Patent number: 5066167
    Abstract: The prestressed concrete lining has several reinforcement elements (32) distributed around the circumference and along the length of the pressure tunnel. There are prestressing elements (38, 39, 40, 41) which encompass at least a part of the circumference of the pressure tunnel. A bottom part (35) is disposed within the pressure tunnel, formed of several elongated anchorage bodies (15) in series. Each of the anchorage bodies (15) has an essentially U-shaped cross section. In each of the arms (2, 3) of the anchorage bodies turned towards the inside of the tunnel there are first means (5) for passing through at least one of each of the prestressing elements (38, 39, 40, 41). An bearing plate (8) is disposed on each of the facing inner surfaces of the arms in the region of each of the first pass-through means (5). Second means (10) for passing through at least one of each of the prestressing elements (38, 39, 40, 41) are foreseen in the base arm of the anchorage body 15.
