Component for replacing pipes, method of use, and kit of parts for use in removing pipes
This invention relates to an improved component (10) for replacing pipes, in particular underground pipes. The invention also relates to a trenchless method of removing pipes using the improved component, and a kit of parts for use in removing pipes. The improved component (10) is securable to a cable (14) and has a body (30) with a recess (26) to accommodate the end (18) of the pipe (12) in use, the recess being surrounded by a collar (24). The improved component is a two-part component, the first part (20) being securable to the cable (14) and the second part (22) including the body, the two parts being made of different materials. There is also provided a kit of parts including cooperating alignment elements of standard dimensions, and a method of removing an underground pipe.

F16L 19/025 - Pipe ends provided with collars or flanges, integral with the pipe or not, pressed together by a screwed member the pipe ends having integral collars or flanges
F16L 3/16 - Supports for pipes, cables or protective tubing, e.g. hangers, holders, clamps, cleats, clips, brackets with special provision allowing movement of the pipe
F16D 3/04 - Yielding couplings, i.e. with means permitting movement between the connected parts during the drive adapted to specific functions specially adapted to allow radial displacement, e.g. Oldham couplings
F16L 1/032 - Laying or reclaiming pipes on land, e.g. above the ground in the ground the pipes being continuous
F16L 55/16 - Devices for covering leaks in pipes or hoses, e.g. hose-menders
H02G 1/08 - Methods or apparatus specially adapted for installing, maintaining, repairing, or dismantling electric cables or lines for laying cables, e.g. laying apparatus on vehicle through tubing or conduit, e.g. rod or draw wire for pushing or pulling
This invention relates to a winch and to a method of using the winch. The winch is ideally adapted for mounting to the boom of a vehicle such as a mini-excavator, and is likely to find its greatest utility in relation to the removal of underground pipes, electricity conduits, fiber optic cables and the like, as well as in the bursting of pipes. The invention provides a winch comprising a support column, a base, a magazine, a drive mechanism and a mounting structure. The drive mechanism is connected to the magazine and is adapted to rotate the magazine in use. The support column connects the magazine to the base. The mounting structure is adapted for mounting to the boom of a vehicle. The winch has a rotatable connection between the base and the mounting structure which is securable in a chosen rotational position, so that the base of the winch can be correctly aligned regardless of the orientation of the vehicle.

IMPROVED APPARATUS AND COMPONENT FOR REMOVING PIPES
This invention relates to an improved apparatus and component for removing (and perhaps replacing) pipes, in particular underground pipes, as suitable for use in trenchless pipe removal methods such as that of WO 2008/071997. The invention provides a component which is securable to a cable, and which has a sleeve for surrounding an end of the pipe. The component has an opening through which a settable fluid may be delivered into the pipe in use. A surface of the component is adapted to seal the end of the pipe so that the settable fluid may not leak from the pipe before it has set. The apparatus comprises the component, a cable secured to the component, a winch and a settable fluid.
This invention relates to a portable winch assembly (10; 210) comprising a footplate (12; 212), a support frame (14; 214) which is locatable upon the footplate, a magazine (16; 216) which is locatable upon the support frame, and a drive mechanism (22; 222) which is connectable to the magazine to drive the magazine to rotate. The foot plate, support frame, magazine and drive mechanism comprise separable components which may be transported separately to a site of use and assembled into the winch at the site of use. The invention can provide a portable winch assembly capable of generating a tensile force of up to 10 tonnes, and is therefore suitable for pipe pulling and pipe bursting applications for example, and yet is made up of parts which can readily be carried to the site of use, which site of use may be inaccessible for vehicles.
This invention relates to a method for replacing pipes, and an apparatus therefor. The method utilizes a cable which is passed along an existing pipe. The cable is connected to a component at the end of the pipe, the component also being connected to a length of replacement pipe. The cable is pulled whereby the existing pipe is removed and the replacement pipe inserted in its place. The invention is expected to achieve its greatest utility as a method and apparatus for replacing pipes carrying water or gas to domestic and commercial properties.
