摘要： A portable winch and method of use is shown. One advantage of winches shown includes an ability to lower a boom or boom sections into limited access exit pit for winching operations such as pipe bursting. Sectional boom designs shown provide the ability to easily raise and lower a boom large distances without the need for a single long boom. Selected winch designs shown include flexible inserts between the boom and the winch frame that help resist damage from unforeseen shifting of the device during operation. Designs and methods shown also include multiple pulleys on a boom end unit. Fasteners are shown that reduce build up of debris.

摘要： A system for pushing and pulling rod strings through the ground or an underground pipe. The apparatus has a downhole tool attached to the distal end of the rod string. The push/pull machine has a stationary frame that is placed against the ground to provide a reaction surface. The stationary frame has an opening for the rod string to pass through. A rod gripping assembly is supported on the machine frame and moveable relative to the stationary frame. The push/pull machine has a powered rod section spinner to add or remove rod string sections from the rod string. An actuator powers movement of jaws into a spinner bowl to cause a powered gripping of the rod string section. With the rod string section gripped a motor is activated to rotate the rod string section to connect it to a rod string or disconnect it from the rod string.

摘要： A cable retention and release mechanism includes a cable gripping device including a cable passage. A cable extends through the cable passage. A cable gripping device collar is movably coupled around the cable gripping device. An outer cable gripping device surface is seated against a cable gripping device receiving inner surface preventing movement of the cable gripping device relative to the cable gripping device collar. The cable gripping device receiving inner surface clamps the cable gripping device on the cable and prevents sliding movement of the cable. A jack is movably coupled with the cable gripping device collar. In a first engaged position the jack is engaged against the cable gripping device proximal end. In a second engaged position the jack unseats the outer cable gripping device surface from the cable gripping device receiving inner surface and releases the clamping of the cable.

摘要： A drawing device 4 is mounted in a drawing shaft 3, and pipe replacement device A connected with new pipes is arranged on the side of starting shaft 2, wherein the drawing device 4 and the pipe replacement device A is connected through pull-rods 5 inserted into existing pipes with each other. The pipe replacement device A is comprised of a cutting part 11 including cutter bodies 14 (shanks 14a to 14i) arranged in the axial direction and at angular intervals in the circumferential direction, an expanding part 12 having expanding rollers 18a to 18f, and a connecting part 13. Each cutter body 14 has a plurality of cutting edges, wherein distances between the respective cutting edges and the center of the circle become larger in order from the forward side toward the backward side. While the pipe replacement device A is traveled in the inside of cast iron pipes, the inner wall of cast iron pipes is cut by the cutter bodies 14 to form grooves. Splitting of existing pipes into arc-shaped pieces 1a is made starting from the grooves. Arc-shaped pieces 1a are pressed into the ground, by which a tunnel 7 surrounded by arc-shaped pieces 1a and portions of consolidated earth is formed, while new pipes 6 are introduced into the tunnel 7, and besides the new pipes 6 are protected by protective armors formed of arc-shaped pieces 1a.

摘要： A method and an apparatus for new installation or bursting and replacement of underground pipelines, without the necessity of trenches. This method and apparatus allows for the installation without the need for large excavations at the end point of the line and allows for nondestructive termination at an existing vault, structure or manhole without having to rebuild the structure, vault or manhole. The apparatus includes a head assembly that breaks apart fracturable pipe and expands the hole to accommodate the desired size of pipe. Because of the method of applying forces, the expansion of pipe diameter can be very substantial. Because of the head assembly, the head can be disassembled as the pipe and head enter a manhole, vault, structure or limited space and thus no need to excavate the vault or structure or create a large end excavation is necessary, thus saving time and money and avoiding disruption of traffic in street locations.

摘要： A method of replacing an existing underground pipe (44) with a new pipe (48) comprises the steps of moving a pipe removing tool (70) along the existing pipe (44) to remove the existing pipe and dragging the new pipe (48) behind the tool (70) to replace the existing pipe while imparting vibratory motion to the tool (70) or continuously applying a dressing material ahead of the new pipe to act as lubricant or to fill in the annular space between the new pipe and the surrounding soil. According to another embodiment, the method comprises the steps of pushing out the old pipe (126) in one direction by means of a pipe removing tool (110) connected to a hydraulic unit (10) through a stem and replacing the old pipe (126) by means of a new pipe (48) by dragging the new pipe along behind the stem moving in the opposite direction during a return run. Pipe removing tools (70, 110) are further provided which are capable either of fracturing the old pipe or extracting the old pipe and having chambers (86) for feeding a lubricating or filter material or provided with a vibrator (105) therein. A hydraulic unit (10) for driving the pipe removing tools is also provided which is associated with apparatus (40) for gripping and rotating the stem to effect assembly or disassembly of the stem from individual screw-threaded pipe sections (38).
摘要翻译：用新的管道（48）代替现有的地下管道（44）的方法包括以下步骤：沿着现有的管道（44）移动管道移除工具（70）以移除现有的管道并拖动新的管道（48）在工具（70）的后方更换现有的管道，同时向工具（70）施加振动运动，或者连续地在新管道之前施加敷料以充当润滑剂或填充新管道和周围环境之间的环形空间泥。根据另一实施例，该方法包括以下步骤：借助于通过杆连接到液压单元（10）的管道移除工具（110）将一个方向上的旧管道（126）推出并更换旧管道（126））通过在返回运行期间沿相反方向移动的杆沿着后部拖动新管道（48）。进一步提供管道拆卸工具（70,110），其能够破坏旧管道或者抽出旧管道，并且具有用于供给润滑或过滤材料或在其中设置有振动器（105）的腔室（86）。还提供了用于驱动排管工具的液压单元（10），其与用于夹紧和旋转杆的装置（40）相关联，以实现杆从单独的螺纹管段（38）的组装或拆卸。
