LARGE 1970’S HOUSING ESTATE DUCTILE IRON PIPE PROJECT
A major UK contractor in the South of England had a large scheme where they had to replace an ageing 6” ductile iron pipe by sliplining. The scheme was on a large 1970’s housing estate and involved several hundred cut outs. What made this task particularly problematic was the sheer number of other services crammed into the excavation, as can be seen in the photograph above.
It was decided to use the hydraulic ICS 880F4 PowerGrit Saw for this task. Cuts were made both freehand and by utilizing the adjustable pipe clamp where space allowed. The images show how small an excavation PowerGrit can be used in and just how close to other services it is possible to safely cut the pipe.
No other method of pipe cutting could have been used without completely exposing the whole length of the water main, which would have significantly increased the cost and duration of the project.
The saw uses a diamond chain that has a grinding action and has no kick back, also due to the length of the bar and chain, cuts can be made from one side thus making PowerGrit an efficient and safe method of cutting.
By using ICS PowerGrit on this scheme a great deal of time and money was saved. Throughout the task PowerGrit proved to be safe and reliable.
