A compact open-path horizontal trenchless pipe ramming device for short distance horizontal drilling and which accommodates off-the-shelf standard plastic or steel pipe stems in a range of pipe diameters. The device is lightweight and competent to retrieve a drill string and attached cable or replacement pipe.
An articulating, rotating pipe bursting head device is provided. More particularly, the improved pipe bursting head device disclosed herein comprises a coupling means at the back or posterior end of the bursting pipe head device which connects the bursting pipe head device to the replacement or product pipe, typically through a universal duct puller attached to the front or anterior end of the product pipe. In one preferred embodiment, the coupling means allows for articulation of the replacement pipe relative to the bursting pipe head device. In another preferred embodiment, the articulating coupling means allows for articulation from 0° through 90°. In another embodiment, the coupling means allows for rotation of the replacement pipe relative to the pipe bursting head device. In another embodiment this rotating coupling means allows for 360° rotation. Thus, the present disclosure describes an articulating, rotating bursting pipe head device and method of use.

Provided are articulating, rotating pipe bursting head devices for bursting a buried pipe and simultaneously pulling a replacement pipe through the same location. The bursting heads can comprise an integrated, substantially hollow cone body having one or more cutting knives arranged radially about its outer surface, and an end cap at its posterior end. Protruding from the posterior end of the end cap is a swiveling quick release coupling means for linking the bursting head to a replacement pipe carrier such as a universal duct puller. The swiveling quick release coupling means allows for rotation and articulation of the replacement pipe relative to the bursting head during operation, enhancing entry of the replacement pipe into an existing pipe underground. The bursting head body further can comprise an axial opening at its anterior end for receiving a cable, an internal magnetized cable gripping mechanism and a quick-release tool.
