ToughButterCup Posted April 28, 2020 Share Posted April 28, 2020 Trench dug ✔️ Gravel delivered✔️ Pipes delivered ✔️ I/Cs delivered ✔️ Overthinking done ( i.e. @Russell griffiths consulted) ✔️ BCO consulted ✔️ "Send me some photographs of the trench just before you want to back-fill it " "I/C in place ?" "Yes" I'm trying to avoid the situation where she looks at the photos and, sucking her teeth, says .... "Yer gonna have to take that out and ....... " Tips please 1 Link to comment Share on other sites More sharing options...

ToughButterCup Posted April 28, 2020 Author Share Posted April 28, 2020 Just rung her. She says ........................... Its OK. 344mm wide 1 Link to comment Share on other sites More sharing options...
ToughButterCup Posted April 28, 2020 Author Share Posted April 28, 2020 Ok, how's this then? From the first I/C using my laser (spot 30mm above the invert) and looking for 1.4 degrees (thanks @epsilonGreedy - I couldn't work it out for myself) Heres how I judged the gradient The black line is 100mm above ground level - and the laser spot is 30mm above the previous invert - so here it looks like there's 20mm to play with.... and that was 1.4 degrees below the previous one..... all the way ( 8 meters or so) to the next I/C which is a titchy bit off level . The overall line isn't as bad as I thought it was going to be .... although, there's nowt to be lost by nudging the second joint left a bit is there? Right, what have I missed, please?

ProDave Posted April 28, 2020 Share Posted April 28, 2020 Nudge that second joint left a little to straighten it. Fill with gravel so the gravel comes half way up the pipe along it's whole length. Photograph it for BCO. Link to comment Share on other sites More sharing options...
Oz07 Posted April 28, 2020 Share Posted April 28, 2020 Are any of those ic's in a traffic area? I usually bed the bases on a semi dry conc mix. Link to comment Share on other sites More sharing options...
Russell griffiths Posted April 28, 2020 Share Posted April 28, 2020 The last ic in the pics why are you entering on a side branch and not on the main run is there another pipe on the main run I cannot see if you are trying to turn 90degrees you would normally rotate the ic so you stick to the main run using two 45 to make back to 90 but you know this, so there must be more to that pic.

I did just as @AnonymousBosch has shown for the final turn from the main run into the treatment plant. I certainly am not going to change it now.
