Abstract

See full text

Described herein are multi-tool boring systems and methods of operating such systems for tunnel boring and/or underground pipe installation. A multi-tool boring system is specially configured for fast installation and replacement of various tools, such as a pneumatic rammer and a hydraulic drive, enabling different operating modes of the system, e.g., pilot tube installation, auger boring, pipe ramming, pilot pullback boring, static pipe bursting, and non-contact boring. In some examples, a multi-tool boring system comprises a track assembly, a jacking frame slidably supported on the track assembly, and an impact plate assembly, which is attached to the jacking frame and comprises an impact plate and shock absorbers between the impact plate and the jacking frame. The impact plate comprises an impact plate opening configured to engage and support a pneumatic rammer. The rammer can be replaced with a hydraulic drive with a shaft protruding through the opening.
