摘要： PURPOSE:To facilitate the cutting of a buried pipe and to promote the replace ment by non-cutting by inserting a supporting material advancably and retreatably into a buried pipe and by providing a cutting device rotatably, vertically movably and advancingly and retreatingly thereon. CONSTITUTION:The supporting material 1 in tubular shape is extended in the optional length with its addition inside a buried pipe X. A work pipe 22 is provided advancingly and retreatingly on the base 20 at the tip of the supporting material 1 and a cutting torch 23 is fitted via L shaped fitting 24 to the tip as well. And the torch 23 is provided advancingly, retreatingly, rotatably and vertically movably by motors 211, 221 241. In this composition the supporting material 1 is extended in the prescribed length and the cutting is performed by performing the alignment of the torch 23 by utilizing the TV camera of a remote control device 3. The cutting of the buried pipe x is therefore facilitat ed and the replacement work of non-cutting can be promoted.

摘要： PURPOSE:To exactly cut off a steel pipe sheet pile by a method in which high- pressure water is supplied into the water jet nozzle of a cutter fixed to the inside of a steel pipe sheet pile and jetted, and the nozzle holder is turned toward toward the circumferential direction of the steel pipe. CONSTITUTION:In cutting off a steel pipe sheet pile 1 driven into the ground under water at a given level, a cutter is hung down to a given cutting position in the sheet pile 1. A pressing part 11 is contacted with the inner wall (a) by an oil-pressure device 12 to fix the cutter B. The motor 25 of a vertically mov able driver 5 is operated, and the screw shaft 24 is turned to regulate the height of a nozzle holder 3. Afterwards, high-pressure water is supplied to water jet nozzles 6a and 6b through a supplyer 7 and jetted, and the motor 19 of a rotary driver 4 is driven to turn the nozzle holder 3, thereby cutting off the sheet pile by the water jet in the circumferential direction of the steel pipe.

摘要： PURPOSE:To make it possible to perform the cutting work efficiently and precisely, by performing the level adjusting as fixing a cutting device main body to the inner wall of a sheet pile main pipe, and cutting the sheet pile main pipe and a joint part with a disc cutter and a water jet nozzle. CONSTITUTION:A cutting device (alpha) is brought down as it is suspended, to the preset position where a sheet pile main pipe A should be cut, each of contacting members 16 of holding units 2 is pressed against the inner wall (a) of the main pipe A, and this device (alpha) is fixed to the inner wall (a). In this situation, the position of a cutter is adjusted through slidingly bringing up/down a cylindrical body 6 and a nozzle holding body 9 relatively to a horizon tally moving body 5. Next, a disc cutter 8 is made rotatingly cut into the inner wall of the main pipe A, revolved through rotating a rotor 3 with a rotation driving unit 4, and the main pipe A is cut along the circumferential direction. Moreover, to cut a part of joint with a water jet nozzle 11, the cutter 8 and the nozzle 11 are shifted upward/downward. After that, the nozzle main body is moved back/forth by a cylinder unit 12, and the joint part is cut as spouting high-pressure water from a nozzle opening.
