BORING ( Not You Nick )

jmic

I in the past had to run a water line across Rt.202 for an office building I was building. I know this road had 6" or so of concrete plus multiple layers of asphalt so to me cutting the road to get to the other side wasn't an option unless absolutly necessary. What we did was make a point onto 3" black pipe and digging down on each side of the highway making a pit we pushed the pipe through under the road in 5' lengths, with the backhoe , it actually worked with out any problems or piercing the water main . I might add this was 20 yrs. ago, don't even know if this would be feasible now a days with everything else that they run under roads. Have any of you guys doing all the trenching and pipe work used any similar techniques, or any of the new hydraulic boring machines to get utilities under ground and how were you're experiences doing so?

the closest horizontal pipe and jack boring crew we have is 140 miles away. and he is rather shoddy in his bores. i don't know if it's his setup or what, but rarely comes out exactly where we need him. if it's a critical bore, i hire a crew from near omaha, nebraska. they're really great. there are 2 crews here that do directional boring that we'll use on small diameter water jobs.

We have a 3" Grundomat pneumatic missile for running service lines across the road. You can find these to rent up to a 6" size. They work well as long as your not in rock. We have a small Mclaughlin boring machine for dry auger boring that we use for 8"-12" bores/40' or less in distance. Anything bigger or longer we subcontract out to an "expert" .

jmic, forgot to add. for us to push rods is rather tough here without using water, either it's in gravel/sand, or an extremely tight clay.

we push steel with the hoe when its small distance, like side walks or narrow roads, we have used the pneumatic mole some but some of the utils inspectors dont like um used, it seems some jug head types in the past have run them up thru the surface or something like that. I think its best to sub such work out to a trusty fellow with a bore when possible.

We've done a couple of dozen pipe borings. For short jobs in good digging we have used our Air Knife to blow holes up to 15' ( 8' from each direction.) Most jobs have gone well. The accuracy is not the greatest.

We tried to go under a driveway in the middle of January one year. There was 2' of frost on each side of the driveway. We set the machine with a slight pitch to it. When the mole had gone farther than the width of the driveway and it couldn't be found. We dug down and found it 3' lower than it should have been. We backed it out and moved it over. Same result. We moved over and started 1 1/2' lower and level. It comes out right on target. 3' of frost in the middle?

The local water company guys said they own one. Its under RTE 202 in Litchfield. It hit an area 1/2 way across a concrete and asphalt State Highway where it just lost movement. They think its a wet spot where there is no friction for the machine to move itself.

A bunch of other little things have gone wrong. Most of the time it has worked. All jobs were 4" or 6" pipe using a mole that pulls the pipe with it.

Oh, I hope it wasn't too boring Joe.
