  • METHOD AND APPARATUS FOR TRENCHLESS EXTRACTION OF PIPE
    Publication number: 20230366485
    Abstract: Apparatus for trenchless extraction of pipe includes a housing rigidly connectable to a pipe to be extracted, a tension helmet disposed over an end of the housing, the tension helmet connected by tensile elements to a hydraulic impact hammer supported by the housing, and resilient shock absorber disposed between the tension helmet and the housing. The hammer is operated to impact a striker plate on the housing, which drives the pipe to be extracted forward and thereby creating a gap between the striker plate and the hammer and compress the shock absorber. The shock absorber then resiliently expands, thereby pushing the tension helmet forward and bringing the hammer back into alignment with the striker plate.

  • Pipe ramming system with hydraulic crowd
    Patent number: 10774592
    Abstract: A horizontal pipe ramming system includes a hydraulic crowd system. A hydraulic percussive hammer is mounted on a carriage that is urged forward by hydraulic cylinders acting between the carriage and an abutment. The continuity of crowd is enhanced by a compressive resilient assembly that releases its energy to the hammer to keep it in contact with the pipe after impact.
