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.

Multi-tool boring systems and methods of operating such systems

Systems and methods for installing pipe underground are disclosed. The system includes a pneumatic rammer configured to provide a percussive force to a section of pipe. The system also includes a main jacking frame coupled to the pneumatic rammer, the main jacking frame including a surface for contacting the section of pipe. The system also includes one or more hydraulic jacks coupled to the main jacking frame and configured to provide a hydraulic force to the section of pipe. The system also includes a set of tracks coupled to the main jacking frame, the set of tracks permitting the main jacking frame to slide in a longitudinal direction. An independently displaceable soil-clearing system can be included to clear dirt coming inside the pipe during the installation and add extra jacking force as needed.
