Someone asked, so let me clarify.

Our typical trench for a sleeve is 24" and when we put the sleeving pipe in the trench we also install the laterals or mainline piping at the same time along with any control wires. At the end of each lateral or mainline pipe, we install a 90 elbow, glue a 5'-6' piece of pipe with a cap on it, then wrap the control wires around the pipe. We pound 3 grading markers around our pipe stubs with some fluorescent marking tape and paint the pipe/cap with bright colored paint.

After paving and flatwork we return to install the irrigation. At the end of each sleeve we excavate down just enough to cut the pipe to glue on another 90 elbow...then run with it.

Sometimes our sleeves end up 3 feet plus down, so if we did not already have our lines already installed from when we installed the sleeves we would have not only have to dig down to locate the sleeve; we also would have to clear enough room to push the pipe through the sleeve. Many of our projects require 2.5" or 3.0" mainline which does not flex much, so at times you would have to not only dig the end of the sleeve, but also run a gradual trench just to install the pipe in the sleeve.

Hope this makes more sense and we have been doing this for 15 plus years with great success. Our crews really do not know any other way at this point.

We send shop drawings with the crews noting the sleeve locations along with pipe sizes and wire that requires installation within the sleeves.
I like it! TY!
