摘要： The present invention is an earth discharging device comprising: an earth discharging pipe which is disposed in a longitudinal direction in order to discharge downward earth and sand that have been excavated by an upward-facing shield machine which advances upward an elastic film-type valve which is provided in this earth discharging pipe, and which expands and contracts diametrically by means of fluid pressure to open and close the interior of the earth discharging pipe and a gate mechanism which is provided further toward the outlet side of the earth discharging pipe tha n the elastic film-type valve, and which adjusts the sectional area of the spa ce through which earth and sand pass inside the earth discharging pipe through which earth and sand pass. By using the gate mechanism to narrow the sectional area of the space inside the earth discharging pipe at the outlet side of the elastic film-type valve, the earth and sand at the outlet side of the elastic film-type valve become slightly blocked, thereby raising the earth pressure of the earth and sand such that the earth pressure at the outlet side of the elastic film-type valve can be made substantially equal t o the earth pressure at the inlet side. Thus, a substantially uniform earth pressure acts upon the entire elastic film-type valve, wherebythe elastic film-type valve expands substantially uniformly so as to narrow the entire interior of the earth discharging pipe substantially uniformly. As a result, blockages and eruptions of the earth and sand can be avoided, and earth pressure control at the work face can be performed reliably regardless of depth or soil type.

摘要： In a cutter structure for a shield machine which advances by boring through a tunnel wall from inside an existing tunnel, the shape of an excavating surface on a work face formed by a cutter is set so as to have a smaller curvature than or an equal curvature to the curve of a surface to be excavated on the outer face of the tunnel wall to be excavated. Since the shape of the excavating surface on the work face formed by the cutter is set by a curvature, upon advance of the shield machine by boring through the tunnel wall, the tunnel wall to be excavated, the shape of which is cylindrical, can be cut into by opening a hole which extends diametrically outward from the central portion of the cutter. As a result, the sections that are not cut into remain connected to the existing tunnel and will not enter the cutter chamber in lumps.

摘要： PROBLEM TO BE SOLVED: To provide a device for preventing rolling of a shield machine capable of surely preventing the rolling regardless of depth or soil quality. SOLUTION: The device is provided with a rod support hole 7 provided to communicate with the inside and outside of a shield frame 2, a penetration rod 5 inserted and supported in the rod support hole 7, a pushing mechanism 13 for pushing the rear part of the penetration rod 5 and pushing out the penetration rod 5, and a new penetration rod 5a interposed between the pushing mechanism 13 and the penetration rod 5. The rolling of the shield frame 2 can be prevented regardless of the depth or the soil quality by protruding the penetration rod 5 from the rod support hole 7 to a side part ground. A rolling prevention measure can be considered any number of times by piecing and pushing out the new penetration rod 5a from the inside of a shield machine even when the penetration rod 5 is bent by boring resistance. In addition, the rolling prevention measure can be cancelled by pushing out to abandon the penetration rod 5 to the side part ground.

摘要： PROBLEM TO BE SOLVED: To provide a longitudinal-lateral shield machine and a pipe jacking method, by which the bottom section of a longitudinal tunnel can be excavated in depth deeper than the position of the starting of a lateral tunnel by a simple longitudinal shield machine. SOLUTION: The longitudinal-lateral shield machine is composed of the longitudinal shield machine constructing the longitudinal tunnel and a lateral shield machine constructing the lateral tunnel crossing with the longitudinal tunnel. A starting window having a diameter approximately the same as the outside diameter of the lateral shield machine is bored to the side face of the longitudinal shield machine. The starting window is installed at a position higher by a fixed distance from an excavating surface at the front end of the longitudinal shield machine. The lateral shield machine is housed in the longitudinal shield machine. The longitudinal tunnel is constructed towards the vertical direction by the longitudinal shield machine, a de-energizing chamber absorbing the energy of water falling on the longitudinal tunnel is built on the bottom section of the longitudinal tunnel, and the lateral shield machine is started towards the horizontal direction from the starting window at a position higher than the de-energizing chamber and the lateral tunnel is built.

摘要： PURPOSE:To connect a shaft with a shield tunnel airtightly by a method in which the area for shaft is excavated by a shield excavator, and thereafter a protective cylinder is projected and pressed on the elastic sealer of the shaft structure. CONSTITUTION:A shield tunnel 4 is excavated right before a carry-over shaft 5, and the excavation is stopped. An over cutter 19 is projected, and a shield excavator 2 is advanced to excavated an excavating area 23 to a space 24 by the cutter 2. After the excavation is stopped, the cutter 19 is retracted, and a protective cylinder 9 is projected and penetrated into an elastic sealer 22. A water-stop agent is injected through an injection tube 25 from the shaft 5 into the surrounding ground for sealing. The remaining excavating area 23 and a thin-thick strength wall 21 are removed by excavation, and the tunnel 4 is connected to the shaft 5. The use of ground hardener can thus be avoided.

摘要： PROBLEM TO BE SOLVED: To provide an earth removal device of an upward shield machine capable of controlling earth pressure at a face by evenly inflating an elastic film type valve within an earth removal pipe. SOLUTION: The earth removal device includes the earth removal pipe 19 positioned vertically for discharging downwards the sediment dug by the upward shield machine 1 which digs upwards; the elastic film type valve 20 provided in the earth removal pipe 19 for opening and closing the inside of the earth removal pipe 19 by being radially inflated and deflated by fluid pressure; and a gate mechanism 21 provided in the portion of the earth removal pipe 19 closer to an exit than to the elastic film type valve 20 for regulating a cross-sectional area within the earth removal pipe 19 through which the sediment passes. The cross-sectional area on the exit side of the elastic film type valve 20 through which the sediment passes is reduced by the gate mechanism 21 to rather clog the inside of the pipe and increase its earth pressure while making the earth pressure on the exit side approximately equal to the earth pressure on the entrance side. Thus, the elastic film type valve 20 is entirely and approximately uniformly acted upon by the earth pressure and approximately uniformly inflated, so that the entire valve 20 reduces the cross-sectional area. The earth pressure at the face can thus be controlled regardless of depth and soil quality. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a cutter structure of a shield machine capable of cutting a tunnel wall from the center part outward to a radial direction and preventing a non-cutting part from being taken in a cutter chamber as a lump when the shield machine is started by digging the tunnel wall from the inside of an existing tunnel. SOLUTION: In the cutter structure of the shield machine 3 which is started by digging the tunnel wall 2 from the inside of the existing tunnel 1, an excavation face shape 36 of a cutting face by a cutter 8 is set steeper than a curve shape 37 of a face to be excavated of an outside face of the tunnel wall 2 to be dug. Thereby when the shield machine 3 is started by digging the tunnel wall 2, the cutter 8 can be cut to open a hole by directing the tunnel wall 2 from the center part of the cutter 8 outward to the radial direction. Thus, the non-cutting part 38 always communicates with the existing tunnel 1, and is prevented from being taken in the cutter chamber 16 as the lump.
