ABSTRACT:
A light weight, portable, self-contained pipe joining device and system for installing succeeding, very heavy, concrete pipe sections into the end of a preceding pipe section positioned in a trench. The pipe joining device includes a power operated winch which is mounted on an adjustable height stand which may be mounted on a sled. The adjustable height stand allows the positioning of the winch inside the initial pipe section at the intersection of the horizontal and vertical centerline of the pipe section. The winch cable is anchored to the winch stand, passed through a snatch-block and secured to the winch drum. Secured to the snatch-block is a two part sling with a hook at the free end of each part. The winching cable assembly is led through the interior of the succeeding pipe section being installed, and the hooks are placed over the pipe wall at the far end. The pipe joining device is anchored in the initial pipe section by means of a static two part sling. The anchoring sling is attached to the stand of the pipe joining device, and hooks are fitted to the free ends. The anchoring hooks are placed over the pipe wall at the end of the initial pipe section to which the pipe section being installed is not to be joined. The winching action applies an axial pulling force to the succeeding pipe section, thereby properly seating it into the receiving end of the preceding, initial pipe section. The technique is then repeated for subsequent pipe sections to the capacity of the cable length of the pulling winch.
