Abstract: A hydraulic apparatus for pushing pipe into an underground pipe comprises a hydraulic cylinder mounted on two longitudinally spaced sets of three radially extending, equally spaced legs. The legs have adjustable locking devices for locking the hydraulic cylinder in place as required inside the one part of an underground pipe. The hydraulic cylinder also has a lock plate of a length longer than the diameter of the underground pipe which acts to anchor the hydraulic cylinder in place when the hydraulic cylinder is activated. The apparatus has a head or push plate attached to a ram or piston extending from the hydraulic cylinder and a hydraulic control valve controlling actuation of the cylinder. With the two sets of legs attached, the hydraulic cylinder is placed inside one part of an existing underground pipe which is near the part in need of repair and the legs adjusted to center the cylinder in place. The lock plate presses against the end of the underground pipe in which the cylinder is secured.
