Water line to field hydrant.

[bradblazer]

Trenched in 600' of 1" 100psi coil pipe to a hydrant for the pasture.

I borrowed my neighbor's old subsoiler, bent some 1.25" galvanized on my pipe bender, welded some extra long bolts to the pipe and made some plates to clamp it to the subsoiler.




The funnel contains Yellow77 lube to ease the pipe thru the duct.

Since my Kama has negative downforce, I added the 300# of front weights to the unit.

Nice set up Brad,

I guess it worked good? I like your funnel idea to guide the pipe. I need to do something similar but not for water. I have exposed, live overhead wires to power my driveway gate (120 VAC). I want to snake bare aluminum wire into black poly pipe just like yours and bury it. Probably not code but cost effective. I was going to dig a 500 foot trench to bury two home made power cables. You think I could use a sub soiler instead? Should I snake the wire through the pipe first? or bury the poly pipe then snake the wire through it? It's bare 00 aluminum wire used for high voltage overhead power lines. The electric coop left what seems like a 5 mile spool on my property in trade for some solid rock blasting to place two power poles.

Sheist! I had a second post that didn't go in last night. I must have been half asleep and forgot to finally hit "post reply." I'll re-post my other pics when I get a chance.

Larry,
It worked surprisingly good! The key is to make a dry run first to make sure it will go deep enough plus the penetration rate is limited by the trailing guide pipe. The drought here has let up some so the soil is not so hard. I idled along in 1 low and the speed was good.

Can you get a continuous pipe? Some places seem to have it.

That would help with pulling the wire in after burial. The couplings I used were internal double barbs and you would need to ream the ends nice to minimize interference with pulling in the wire.
A continuous coil would also help if you pull the wire in advance since you wouldn't have to worry about running hose clamps thru the guide pipe.
Making the run as straight as possible will help with pulling. Putting the wire in first is not too bad of an option either. Do it alongside the route and lay it in.

That pipe seems to have pretty good dielectric strength. I tried to use regular insulated wire to bury an electric fence under a gate once. The 15kv fencer immediately sparked thru. I then put it inside some 1/2" coil pipe and it's still good.

Nice going Brad,
Good to see it worked for you. I've seen this method before and have been tempted to try it myself. I've got terrain obstacles that have kept me from doing it though. Someday I'll get up the guts to try it. Mine would be for water as well.

Larry, you might get different responses as to whether or not to bury the pipe first and then pull the aluminum through later. If it was me, I would put the aluminum in the pipe and pull the two together. Murphy's Law...I'd be afraid if I got a kink or if the pipe crushed down somehow I wouldn't be able to pull the wire. That would be my luck. There would be a lot of unknowns that "could" happen. It's not like fastening pipe to the wall knowing there are no sharp bends so pulling the wire after is a breeze.
Just my 2 cents.
