pipe installation
(OP)
We have a tunnel a little over 12’ in diameter in which 2 60” force mains are going to be run. The tunnel will be about 4000’ long. I believe the pipe is going to be rfp or possibly hdpe. I have little experience in this but I have to come up with some installation options to put on our bid drawings. I have been hearing about 2 methods that are probably going to be used….either sliding or carrying the pipe. The tunnel is fairly straight a slight vertical curve will be present. As of now the tunnel is about 40’ deep with 30’ shafts. Can someone give me a rundown of the 2 installation methods….if the sliding method is used do they just fill the invert and push the pipe along the concrete?….if the pipe is carried in there will not be a lot of room for the second pipe to be worked on…how will the connection be made?…….what kind of problem will I have grouting in the pipe after installation….is the grouting needed?
Any infomation on the pipe or installation would be helpful…thanks
