Presentation Transcript
Slide1Trenchless technology inaction Part 1 The “moling” process
Slide2A Workman sets up thecompressor and piping to feed the mole
Slide3Lining up the entry point toensure that the new pipe will arrive in the correct position when it exits the tunnel.
Slide4Preparing the molingmachine itself.
Slide5Guide stays have nowbeen set to ensure the moling machine remains on course during its tunneling
Slide6the moling machine exits from under the obstruction,being moled under, leaving a clear tunnel in its wake
Slide7The open tunnel created by the molingmachine can be clearly seen.
Slide8Workmen carefullylever the new pipe through the tunnel .
Slide9A workman guides thepipe along, as it is levered through the tunnel, so as to ensure it will meet up with the existing pipe.
Slide10And the pipe is through, safely underthe obstruction with no open trenching required other than the short trenches on either side of the obstruction. Moling can only be undertaken in certain types of soil and is not feasible, in rocky conditions.
