Thermal Contraction Control in HDPE HDD
Thermal Contraction Control in HDPE HDD
(OP)
I am designing a 100' HDD under a creek that will connect to Ductile Iron on both sides of the HDD. I am concerened about the thermal contraction of the pipe as it would not be tolerated in this design due to flanged connections. I am uncertain of how to design the concrete collars. My initial thought is that I need to fuse branch saddles to the side of the pipe and then pour the concrete collar, but your advice would me much appreciated..........thanks for any input. By the way this is a 4" main

From my understanding......if you use the wall anchor and anchor block system....the tensile forces will be distributed into the concrete and then into the soil.
