Pipe placement method and apparatus |
摘要 |
A method and associated apparatus are shown for highly efficient manipulation of multiple pipe sections within the close confines of a tunnel formation to construct an underground conduit. Overall production is improved by adapting pipe section transport equipment to quickly deliver multiple pipe sections to a placement site and return immediately with the pipe carriages for a next load. Pipe section placement equipment is adapted to manipulate the pipe sections as delivered at the placement site, without any intermediate handling step, and position the pipe sections according to desired line and grade specifications.
