摘要： An apparatus for replacing an existing pipe. The apparatus comprises a slitter and expander which surround a wire rope. The wire rope is attached to the expander, and the expander abuts either the slitter or a separation tube disposed between the expander and slitter, such that the slitter and expander are pivotable relative to each other. The apparatus is placed in a pipe to be replaced and pulled. While being pulled, blades on the slitter slit the pipe, while a sloped surface of the expander moves the slit sections apart into surrounding soil. A replacement pipe may be pulled by a pipe putter attached to the expander. A beacon may also be disposed within the apparatus to emit a signal for locating the apparatus white underground.

摘要： An internal caisson/jacket leg cutter and method provides a frame having upper and lower end portions. The upper end portion has rigging that enables the frame to be lifted. Extensible arms are movably supported upon the frame. The arms extend and retract along generally radially extending lines. Extension of the arms enables them to contact the inside surface of a caisson/jacket leg and thus center and anchor the frame within the caisson/jacket leg interior. A cutting mechanism at the lower end portion of the frame includes one or more rotary cutters or milling devices that cut the caisson/jacket leg wall as these cutters traverse an arc shaped path, tracking the caisson/jacket leg wall.

摘要： A cutting tool for cutting pipe or the like from the inside out includes a housing assembly. A first blade actuating wedge assembly is inside the housing assembly and is movable along a longitudinal axis. The first blade actuating wedge assembly has multiple first tapered blade actuating wedges. Each cutting blade is supported in a manner such that a position of the cutting blade relative to the housing assembly along the longitudinal axis is substantially fixed. Each cutting blade is coupled to a respective one of the first tapered blade actuating wedges such that movement of the first tapered blade actuating wedge assembly along the longitudinal axis causes each cutting blade in the first plurality of cutting blades to move perpendicular to the longitudinal axis.

摘要： A mechanical pipe cutting device comprising of a shaft body with a tapered spring loaded internal drive shaft, with interchangeable heads of varying sizes. The sole purpose of the tool is to cut pipes of different sizes from within. Each head has multiple spring loaded blades that are forced outwards by downward pressure. The shaft body has an adjustable depth guide so that the downward pressure of the operator forces the spring loaded tapered drive shaft against the pistons holding the spring loaded cutters. This is all driven by some form of rotational motive power. As downward pressure is applied the cutters are forced into the surrounding pipe. On cutting through the downward pressure is released, the blades retract. The tool is ready to be extracted from the inside of the pipe.
摘要翻译：一种机械管切割装置，包括具有锥形弹簧加载的内部驱动轴的轴体，具有不同尺寸的可互换的头部。该工具的唯一目的是从内部切割不同尺寸的管道。每个头部有多个弹簧加载的叶片，通过向下的压力被迫向外。轴体具有可调节的深度引导件，使得操作者的向下的压力迫使弹簧加载的锥形驱动轴抵靠保持弹簧加载的切割器的活塞。这都是由某种形式的旋转动力驱动的。当施加向下的压力时，切割器被迫进入周围的管道。在切割通过向下的压力被释放时，叶片缩回。该工具已准备好从管道内部抽出。
