If your running empty conduits when would you install pullstring as opposed to rope? Tele/Data cables get string, feeders get rope? I knowthe spec calls for pull strings in empty conduits for tele/data but I?m thinkingabout when your running a duct bank and there are some spare conduits. Wouldyou install rope? Thanks.
mule tape. it won't cut the pipe, can be used for measuring and pulling
most lighter pulls, and generally won't break.
i have mule tape in every conduit before backfilling or slurry. without exception.
i also don't tape up conduits. i use pvc caps.
when i finished pulling out my current job, i had about 3 wheelbarrows worth of
mule tape. money well spent. the backhoe and slurry bill for this job was over $200k.
how far would the money spent on mule tape go towards fixing a pipe you couldn't get
a rope thru? after the rainstorm that dropped over a foot of water in 40 hours, there was
a lot of silt, everywhere. i'd already pulled the big feeders, but there was 5,000' of 2"
that would have been a bitch to blow lines in after the flood.
for people i've worked for in the past i've spent over a day trying to re fish a pipe that
the string broke, and the pipe was over 500' long, and had silt in the pipe.
