ohh what a day!

first off, lemme explain! im a journey level plumber, but get used mostly for welding so i dont do a whole lot of turd herdin'. but every once in a while, the two combine to make one heck of a nasty job for me. this is at a cheese plant, and storm water needs to be kept separate from waste water. waste is everything from rotten cheese to what comes out of the bathrooms. lots of heavily used floor-drains in these places. after everybody decided that the system was a mess, the company had 10-15 trucks out to start demo.it was an old manhole, where much of the drainage connected and went downstream as a main line. it had caved in and brought us all to realize that everthing was undermined from leakage. cut concrete, dig out muck, repair pipes and route to temporary can(receptical to be pumped out to next downstream manhole). this is the way its going to sit until the customer decides what they want to do about all of their rotten old waste pipe. as a welder i put the taps into the "can" wherever it looks like the temporary pipe wants to go.from above:and below: notice the "floaties" i have added more taps after pictures. we get everything tied in, ask the plant to hammer every drain they can find, and cut holes in the "shoring" wherever water comes out to find another pipe. . .. . .anybody have mike rowe's number?bosses stuff:trailblazer 325maxstar 200my stuff:sa 200fronius transpocket 180100 amp Lincoln w/f97 f350 DITKevin
Reply:another pic after adding another tap and combining two 4" lines behind the "can". notice the undermining underneath concrete slab/ footing. hole is about 9' deep with a 10-11' sump where we keep the pumps. concrete cutting crew still has lots of work to do to get back to stable dirt. imo, the only way this plant is going to fix their waste problem is by replacing all piping between use and city. i suggested (cant remember the name of the process) where they pull new plastic through existing pipe with a machine that busts the old out of the way of the new. there is a spray in process that i am not aware of too that may work. cant wait to see what they decide. my bet is that they leave the temporary setup until authorities catch it and want something closer to codebosses stuff:trailblazer 325maxstar 200my stuff:sa 200fronius transpocket 180100 amp Lincoln w/f97 f350 DITKevin
Reply:There is a process that I'm aware of, you pull a resin saturated liner through the pipe. It's kinda like a fiberglass firehose. Once the hose is pulled end to end, it's filled with hot hot hot water under pressure and it expands to the id of the pipe. The heat releases a catalyst and it hardens it into place. That's how I understood it worked anyway. I've only saw it used on vitrified clay pipe though, pic may be a different story. Good luck with your poopy nasty mess.

Reply:92,My sympathies.  I've had the misfortune before of having to splash about with schools of the Western Brown Wrinkle Neck Trout myself.   Don't know if this will be any help to you but here's a link that explains two methods of trenchless drain repair.   One of them is what Austin is referring to in post 3.http://www.trenchless-sewerlinereplacement.com/

Reply:Crap-tastic!  Yeah, with those cured-in-place reline processes, I believe the existing pipe has to be big enough to get the robot in there to do any initial cleanout and later to re-open the laterals.  Also, as mentioned, you don't want to cut down on the effective diameter too much or try to do it in a line with any crazy bends.
Reply:good news is im off of that job for now! went today to a hospital and after shaking hands with the inspector, asked him if he agreed with 3/32 gap, 3/32 land, 1/8 5p root, 1/8 5p hot-pass, and 3/32 or 1/8 lo-hy cap. . . . . "yep, sounds good!"he comes back a few minutes later and tells me i can have a 1/32" gap maximum i cut my stuff apart, and out of spite, fit up tight, whip a root in real quick, (no penetration), gind it shiny and let him look, hoping he would ask why i got no penetration. this was a tee on the end of pipe, he had full access to view the inside."looks great! your ok to fill and cap!" he signs off on it and tells me he re looked at the procedure submitted and says i can run up to a 3/32" gap, but he would rather see it tight.i almost wanna go back to playing in the poo. more plastic welding tomorrow though so that will be a nice breakbosses stuff:trailblazer 325maxstar 200my stuff:sa 200fronius transpocket 180100 amp Lincoln w/f97 f350 DITKevin
