Pretty cool to see the stuff go by. On a similar vein (long things that were thought to be too solid to flex like that) I watched a dig near here where they drilled under nearly a mile of the town, to run a water main (sewer?) under without trenching it in. The pipe was about 24 inches in diameter, and they had it all welded up and snaked back and forth across a field. When the time came to install it, they hooked a shackle to the endcap and winched it through the hole from where it was laid out. One heavy duty spaggetti noodle! Cheers Trevor Jones |
