Message: Sliplining large diameter pipe takes extra planning.
-
As part of a major dam rehabilitation project, an 84-inch arch concrete outlet was slip lined with a 72-inch diameter welded steel pipe.
-
Due to the pipe size and other construction restrictions, the steel pipe was inserted into the outlet in multiple sections. A trolley system for moving the pipe up the conduit was constructed by the contractor in order to both increase safety and to minimize damage to the pipe
-
After placement, the joints between the sections of pipe were welded. Each weld was tested to ensure there were no defects in the joints.
-
Grout injection gallery.
-
This sliplining project had a relatively large annular space to grout. Grout was placed in four separate lifts using a grouting gallery in order to control fluid pressure on the pipe, floatation of the pipe, bleed water from the grout, and the heat produced during the grout curing process.
