    • Apparatus for cutting through a pipe wall under water, as in decommissioning an offshore structure, has a body (16) which can be lowered down the pipe (10) and then locked in position, and a cutting head (20) at the bottom of the body with a toothed disc-like blade (52) which can be advanced radially into contact with the pipe wall and rotated about its own axis to cut through the pipe wall. The cutting head is then rotated and makes one revolution to cut right through the pipe wall to separate an upper pipe section from a lower pipe section. To keep the cut open as cutting proceeds, wedges (62) are fired into the cut around the pipe as the cutting head rotates and leaves an open cut behind it.

    • 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.
    • 目的:为了有效和精确地进行切割作业,通过在将切割装置主体固定在片材主管的内壁上进行水平调节,并且将片材主管和接合部分切割成 圆盘切割机和喷水喷嘴。 构成:切割装置(α)在悬挂时被放下到切割片桩主管A的预设位置,保持单元2的接触构件16中的每一个被按压在内壁(a)的内壁 主管A和该装置(α)固定在内壁(a)上。 在这种情况下,通过相对于水平仪器移动体5相对于圆筒体6和喷嘴保持体9滑动地升降来调节切割器的位置。接下来,将圆盘切割器8旋转切割成内壁 通过旋转驱动单元4旋转转子3而旋转主管A,并且沿着圆周方向切割主管A. 此外,为了用喷水喷嘴11切断一部分接头,切割器8和喷嘴11向上/向下移动。 之后,喷嘴主体通过气缸单元12前后移动,并且将接头部分从喷嘴开口喷射出高压水。
