I need to do a bit of explaining on this one. :laughing:How deep is that trench? looks awful shallow.
The power conduit almost immediately tapers down to about 3' deep (30" minumum) and the phone conduit is only about 12 to 18" deep at this point. To the right just out of the picture the phone conduit tapers down to the depth of the power conduit. When I first started this project I was told that phone service wouldn't be available but they were very nice and gave me a free roll of direct burial wire just in case it became available in the future. My plan was to just lay it in the trench about 18" down thinking I would never get a chance to use it. Then I started thinking about all of the rocks and gnawing animals and thought how stupid this was so I decided to run it in conduit.
Since I started out with only a power conduit I chose to use a 12" bucket. Luckily, I left 18” depth of trench open for laying the wire in so when I changed my mind about the conduit I didn’t have to dig anything back up as I never installed the wire yet. When I started laying the phone conduit I realized that I was doing double the work. Making a nice smooth bed for the conduit twice at 2 different levels and making sure the soil was compacted vertically between the conduits so the top conduit wouldn’t be damaged from settling. Then I got the bright idea to switch to a 24” bucket and lay both conduits in the bottom and be done with it. The hoe digs a 24” trench just as fast as a 12” trench and things are going much faster now. I’m finding other advantages with the wider trench as well but this is getting too wordy.
Fast forward one year later. I received an e-mail from the phone company a few weeks ago saying that the railroad granted permission to cross their tracks with the phone wire. Originally it was thought that the very old poles were only high enough for the power wires and no utilities. I was one happy camper to hear that all of this extra work wasn’t in vain. But if I hadn’t of buried the extra conduit I would have felt horrible. Today and tomorrow there is a crew on location stringing a phone line across the tracks and a 100’ wide river. :thumbup:
Ohhhhhh! I'm such a slow typer. Here is a pic of my 36" radius sweeps that Frenchie mentioned.
