摘要： PROBLEM TO BE SOLVED: To provide a soil improvement method for outside of a separation part of front and rear unit tunnels allowing safe execution of a tunnel connecting operation by ssurely and fixedly soil-improving a separated outer part of unit tunnels adjacent to each other. SOLUTION: A high-pressure jet injection type soil improvement system is mounted on a post-moving shield machine 10, a rod-shaped nozzle 20A of the system is stored in a case body 22A provided on the rear upper and lower part recessed arc sides of a post-moving shield 11, and the nozzle 20A is fixed to the post-moving shield machine 10 so that a tip part having an injection port is projected to the outer rear side of the case body 22A. A soil-improving material is injected from the nozzle injection port to a distant outside opposed part 4" on the covering surface of a preceding unit tunnel 1 while the post- moving shield machine 10 is excavating so as to form an improved body 4'. Next, after a jack is extended, back-filling is performed on the rear side of the improved body 4', and then, after the jack is retracted and a new forwardmost segment is assembled, the above step is repeated.

摘要： PURPOSE:To reduce the occupied area on the ground so as to reduce the effect on the road-surface traffic, beautiful sight, existing burial facilities, and reduce the volume of earth to be excavated and the volume of earth to be refilled to economically construct an underground space. CONSTITUTION:A supporting pile 11 is driven from the ground surface, and a starting shaft 12 for operators driving curved pipes, etc., is constructed around the upper end part of the supporting pile 11. Plural curved columnar bodies 13 made of downward-curved pipe, etc., are driven from the starting shaft 12 in a radial manner. Then, the upper end part of the supporting pile 11 and the curved columnar bodies 13 are integrally connected with each other to form an umbrella ribs-shaped supporting body 10 under the ground. The ground covered with the supporting body 10 is excavated, the excavated earth and sand are conveyed through the starting shaft 12, and the surrounding ground is lined to construct an underground space.

摘要： PROBLEM TO BE SOLVED: To force-feed a casing without excavating and discharging soil, by rotating the casing in which a tubular body or a screw rod is provided along the inner wall face and jetting a pressurized fluid from the tubular body and rotating the screw to form a low density zone of soil at the inner wall face of the casing. SOLUTION: A cylindrical casing C made of steel or the like is the front head casing for the construction of a shaft. An excavating cutter C2 is fitted to the lower edge C1 and a tubular body 1 is detachably provided vertically to reach almost the lower edge C1 at the inner wall face C3. The front head casing C is set to a shaft-construction machine and rotated to settle the casing by the force-feeding action while excavating the ground by the excavating cutter C2. Compressed air, pressurized water, or mud slurry according to a soil quality, is jetted from a plurality of ejection holes 1C formed on the tubular body, from a pressurized fluid supplying device through a swivel 3 or the tubular body 1, while excavating the ground. The front head easing C is pressed in the ground while forming a low density zone G2 over the whole peripheral part near the inner wall of the casing C.

摘要： PROBLEM TO BE SOLVED: To heighten workability by providing a bearing part with contact parts to come in contact with a plurality of places of a buried pipe, and providing a belt for holding the buried pipe in a constrained state jointly with the contact parts, and a belt tightening means. SOLUTION: A bearing part A1 of a feed jig A is placed on the upper peripheral surface of a buried pipe P to be connected so as to bring base plates 3 of contact parts C into contact with the upper peripheral surface. A belt 7 is wound around the lower peripheral circle of the buried pipe P, and a hook 7a is fastened to a support rod 2a. A handle 11 of a tightening means D is turned to rotate a winding shaft 8 in a tightening direction through a ratchet claw 10 and a ratchet gear 9 so as to hold the buried pipe P in a constrained state by the belt 7 and the base plates 3. A connecting metal fitting W' at the end of a wire W is hooked to a suspension ring 5 of a suspension screw rod 6 of the bearing part A1, suspended by a crane and lowered into a start shaft to place rollers 14 of a guide part A2 on sliding guide rods (g) of a force-feed body. When the pipe axes of a preceding buried pipe and the buried pipe P do not coincide with each other, an adjusting nut 15 of the screw rod 6 is rotated to move the buried pipe P vertically, thus making the axes of both pipes coincide with each other.

摘要： PROBLEM TO BE SOLVED: To excavate and discharge soil in a shaft, by rotating a screw conveyor fitting an excavation cutter at the lower end, together with a casing, when constructing the shaft by pressing in with rotation the casing having an excavation cutter fitted at the lower end. SOLUTION: In the construction of a starting shaft or an arrival shaft for installation of sewage pipes or a manhole, a casing C in which an excavation cutter S is fixed to the lower end edge is pressed in with rotation by a shaft- construction machine and the subsequent casings C are connected in sequence. A guide plate 1 is detachably laid at the upper end edge of this casing C and a screw conveyor 2 is inserted in the guide hole 1a to be vertically and horizontally transferable and suspended by a hook 7 of a crane. In this way, the screw conveyor 2 is horizontally transferred along the guide hole 1a while rotating together with the easing C and the excavating cutter 4b is rotated by a motor 6 to excavate the soil G in the shaft and discharge it from the discharge opening 5b to the outside. Accordingly, the soil G in the shaft can be excavated and discharged to the outside while the casing C is rotated and driven in.

摘要： PROBLEM TO BE SOLVED: To correct the direction by measuring the deviation of a pilot pipe row by drilling in the false direction of an excavation cutter by a position sensing means, directing the eccentric direction so as to receive reverse deviated earth pressure in a pressure-change receiving surface and conducting the drilling. SOLUTION: A target T is disposed at an opening end on the departure shaft side of the hollow pile of a pilot pipe row and a transit C at an opening end on the arrival shaft side. The pilot pipe row P of a first step completely excavated while directly viewing the target T by the transit C is guided while being taken into a screw 4, a screw pipe row 4b and an inserting port 7, and an excavation cutter 3 is rotated and drilled by a pusher arranged to a departure shaft. When the deviation of the pilot pipe row from a laying projecting line L is recognized, the eccentric quantity and eccentric direction of the excavation cutter 3 are measured, drilling is stopped and a deviated earth-pressure receiving surface 8b is directed so as to receive deviated earth pressure perverse to the eccentric direction, and the drilling is performed and the direction is corrected by the eccentric quantity, thus accurately laying a buried pipe.
