NW Ohio,near Findlay | I was always told the spring line is about a third of the way up on tile. In commercial, city work we have to undercut grade at least 2 or 3 inches, then add stone to grade, bed the tile. Lay tile and cover tile, at least 2 inches over tile. Takes a lot of stone.
On your job, how are your grading the trench? receiver on boom set at a pre positioned angle or what, just asking. Or do you have a man in trench with grade rod? We at the time were using a magnetic receiver attached to boom with stick straight and bucket flat. It would get you close to grade then man in trench would use pole with another receiver to let hoe operator where to cut. May sound crude, but is sure was better than batter boards with string. See how many Ag Talkers know what that set up was in laying tile. Now back to your trench, if I was digging that, all those clods with be falling back in trench, dirt so close to trench. Most of the time we laid dirt one way, would walk, work off other side. Most of the time would have three men on job, if bedding tile would have four men. Top man was the boss, his job was the most important, called for tile , run the final grade with rod, trench man was the rookie, did the work, leveled stone for final grade. Of course had the hoe operator and if rocking tile, had a loader tractor man. On deep work, the top man had to be the safety man, watched for cave ins , some jobs we didn't run trench boxes, but now about all big jobs require it.
I'm glad your tool is working in your dirt. Another question, at that depth, why don't your run a large trencher with a groover built into it, too soft? We have in our area guys that can run up to 2 foot trencher for the large mains. | |
