2005 01 10 Pipe InstallToday was more of the same, putting pipe in the ground. What made today "interesting" was having to deal with all the house utilities. The project is now up to the place where the house gas, power, and water lines all cross the driveway and the path of the new pipe. The cross at a very shallow angle so that a lot of the lines are exposed. Already our water line has been broken, although that can't be blamed on the contractor since there was no metal marker wire in the ground alongside the 2" flexible plastic pipe. This is also the deepest section of the pipe. At this point the bottom of the pipe is 15 or more feet deep. (This is the part of the yard that kept us from doing the open channel solution to this problem. If we had done an open rock lined channel it would certainly have been attractive, and it would have been cool to have a bridge, but it would also have been very wide. The channel could not have sides steeper than 45 degrees, and the deeper the channel the wider it gets given constant slope sides. We would have had a channel that was 26-28 feet wide in this part of the yard. Far too wide and deep.) Because of the difficulty getting around and under all these lines only two sections of pipe went in. But it was a lot of fooling around. In this next shot you can see all three utility lines. The left most (the "bent" one) is the flexible water line. The middle is gas, the bottom, power. One of the workers holds the water line out of the way while the trench is dug out. I am impressed with the delicate touch that is possible with the excavators. The operators are good. A new section of pipe in place. Preparing for another section. Prior to this a lot of digging was done so the trench box could be dragged forward. The creek is not stopped so water is flowing into the trench. They stop it for the last bit of digging before putting in a section of pipe, and then wait for the water to drain before dropping gravel in and placing the section. After two sections of pipe went in they did a lot more digging to move the trench box and get ready to place the last bend. The piece of plywood keeps dirt and rock out of the pipe. A fine mess.
