摘要： PURPOSE:To improve work efficiency in exchanging an obsolete existing pipe such as a cast-iron pipe for a new pipe without open excavating by inserting a joint cutting device in the existing pipe and cutting the joint over a predetermined length in the axial direction removing it and then, inserting a new pipe with a propelling device. CONSTITUTION:In exchanging work, a joint cutting device 10 which is movable in an existing pipe 1 is inserted into the pipe, the joint 2 of the existing pipe 1 is cut at a plurality of points by a vertical cutter 16 and a horizontal cutter 15 over a predetermined length in the axial direction, and front and rear of the joint 2 in the cut length in the axial direction is cut by a circumferential cutter 13. Next, a cut piece of the joint is recovered in the cut piece container by a cut piece recovering device 20, and then, the ground on the outer circumferential side of a general part of the cut existing pipe 1A from which the joint 2 was removed is excavated by an excavating pipe 33. After that, a new pipe 5 is connected to the rear of the excavating pipe 33 and both the pipes 5 and 33 and propelled for a predetermined distance by a propelling device 8, and then, the general part of the cut existing pipe 1A is made to pass the new pipe 5 with held by a holding clamp to be removed.

摘要： PURPOSE:To replace an existing pipe easily with high efficiency. CONSTITUTION:After cutting an existing pipe 1 circumferentially at spaces in the pipe axis direction by a cutting device 2, the outer peripheral ground of the existing pipe 1 is excavated ahead by an advancing pipe 3 with its inner diameter larger than the joint outer diameter of the existing pipe 1, and the front part of a propulsion pipe 3 that can pass outside the existing pipe 1 is connected to the rear part of the advancing pipe 3. The cut existing pipe is then held by fitting/removing mechanism 5 in a removing device 6 so as to be moved into a start shaft 7. While repeating the circumferential cutting of the existing pipe 1 by the cutting device 2 and the movement-removal of the cut existing pipe by the removing device 6, the existing pipe 1 in a unit work block is replaced with the propulsion pipe 4 that is used as a new pipe.

摘要： PURPOSE:To replace an existing pipe with a new without excavation by giving a cutting line to a joint, rupturing the joint with a projection on an excavation leading pipe, and taking in splinters of the joint into the trunk part of the severed existing pipe using a scraper. CONSTITUTION:At a certain spacing in the pipe circumferential direction, a plurality of cutting lines extending in the pipe axial direction are given to the joint 2 of an existing pipe 1 using a vertical cutter 15 and a horizontal cutter 14 of a joint cutting device 10, which is movable and is inserted in the existing pipe 1, while cutting lines in the pipe circumferential direction are given to both sides in axial direction of the joint 2 using a circumferential cutter 13 belonging to the same cutting device 10. Then an existing pipe carryout machine 30 is inserted in the pipe 1, and an excavation leading pipe 20 having projections in specified position on the inner surface is put on the pipe 1, and excavation is performed forward while the projections are pressed to the outer surface of the joint 2. The severed existing pipe 1A is removed by the carryout machine 30 through a new laid pipe 5 which is coupled with the tail of the excavation leading pipe 20, and another new laid pipe is coupled with the tail of the first-named new laid pipe 5. These procedures are repeated, and thus replacement of the existing pipe 1 with new pipes 5 is achieved.

摘要： PROBLEM TO BE SOLVED: To provide a structure of a partially stiffened pipe body, which enables a stiffener to be provided only in a part with large bending moment produced in the pipe body, enhances economy by reducing the weight of the pipe body, and facilitates work for making a diameter smaller. SOLUTION: This structure of the partially stiffened pipe body, which is used for a repair and reinforcing construction method for installing steel plate pipe bodies 3 and 4 on an inner surface of an existing tunnel or that of a buried pipe 2, is characterized by partially fixing a circumferential stiffener 5 only to a region with large radial bending moment by welding. Preferably, the stiffener 5, in which an end 5a, in the direction of revolution, of the pipe body is formed in a tapered shape, is fixed to the pipe bodies 3 and 4 by welding, so that the production of concentrated stress can be reduced. Additionally, the pipe bodies 3 and 4 are carried into the existing tunnel 1 and the buried pipe 2 in a state in which a diameter is made smaller, and can also be applied to the case of restoration in an installation place.

摘要： PROBLEM TO BE SOLVED: To absorb a large deformation generated by an earthquake, an uneven settlement of the ground, and the like, by using a steel pipe with a large deformation property having a low yielding point and a large extension capacity, to the full length or a part of the piping, in a piping liable to generate a large deformation by an earthquake, an uneven settlement of the ground, and the like. SOLUTION: In a steel piping liable to generate a large deformation owing to an earthquake, an uneven settlement of the ground, and the like, a steel pipe 1 with a large deformation property having a low yielding point and a large extension capacity is used to the full length or a part of the piping, while a steel pipe 2 for normal piping is used at the positions other than the steel pipe 1 with large deformation property. The steel pipe 1 with a large deformation property is a low carbon steel pipe with the extension capacity 40% or higher, and it is adaptable to a large deformation. And by its low yielding point, the deformation property is generated from a low stress area, and as a result, it can follow the deformation of the ground easily, and has also the operation effect to increase the deformation adaptability to an external force.
