A rehabilitation system has been developed for cleaning, testing and slip lining pipe particularly sewer lines while in service. The system includes the use of equipment adapted for use on mobile vehicles to increase efficiency and mobility of the system. The cleaning system utilizes a specialized cleaning bucket that can be pulled from excavations and existing manholes. The testing and lining systems also utilize specialized test mandrels and pulling mandrels for the pipe liner that can be used with equipment operating, in part, from existing manholes.

A method for using a system for cleaning pipe comprising the steps of (a) selecting the length of host pipe for cleaning; (b) accessing the host pipe on both ends of the selected length of the host pipe to be cleaned; (c) positioning a down hole boom vertically in a shaft that accesses one end of th

A method for using a system for cleaning pipe comprising the steps of (a) selecting the length of host pipe for cleaning; (b) accessing the host pipe on both ends of the selected length of the host pipe to be cleaned; (c) positioning a down hole boom vertically in a shaft that accesses one end of the host pipe to be cleaned that has a winch and a guide roller mounted thereon whereby the winch drives a cable down the shaft into the host pipe over the guide roller; (d) mounting a winch on a movable mount positioned at an access area to the end of the pipe opposite to the end where the down hole boom is placed, the movable mount is capable of movement from above the access shaft on the surface into the access shaft to the host pipe; (e) placing a cable between the two winches which can be spooled and released by either winch; (f) attaching a cleaning bucket to the cable whereby the cable and cleaning bucket attachment may be manipulated to move through the host pipe, the cleaning bucket has an open top, open end and a flap door opposite the open end, the flap door capable of opening when pulled in one direction through the host pipe and closing when pulled in the opposite direction while trapping debris; (g) dragging the cleaning bucket through the host pipe on the cable by the winch on the down hole boom to the opposite end of the host pipe such that the flap door is open during the dragging process; (h) reversing the drag of the cleaning bucket by spooling the winch on the movable mount such that the flap door is closed as it collects debris; (i) withdrawing the cleaning bucket from the host pipe through the access shaft by the movable mount and winch; (j) discharging the accumulated debris from the cleaning bucket; (k) lowering the cleaning bucket into the mouth of the host pipe with the winch and the movable mount; and (l) repeating the steps of (g) through (k) to clean the host pipe.
