- Running what I brung and taking what I win
OK here's the deal - I am bidding 1000' of a double run of 5" conduit (2000' total) and 250' of 4" conduit. This is a commercial development, easy access and we will running behind the curb in the ROW. There are 2 curb cuts but the seal coat has not been laid so patching will be easy.
I have ran a lot of shorter runs of 3,4 and 5" conduit for building services and 3 phase transformer pads but never had to install a pull string in them because they were short, from service pole/pedestal to the building. I have the specs from the power and phone co and I am comfortable with the project as far as the digging, conduit installation, etc goes.
My question is how to go about blowing your pull string. There will be 3 pull boxes along the route, approx, 300+/- ft. I have seen Asplundh use little parachutes and I have seen other people use a ball of tapped up rags. I have never done this before, only watched other folks on the jobsite do it.
Any tricks or pointers on how to blow a pull string through conduit? Thanks in advance.
