The Problem:
Installing a large diameter intake pipe while maintaining minimal
disturbance to surrounding railroads, businesses and vehicular
traffic.
The Solution:
Ballast Nedham decided to drive the host pipe with a modified IHC
S-90 offshore hammer. They used Permalok 120" O. D. Casing
to complete the task. The size of the pipe, along with the lengths
of the drives, made this project the largest horizontal driving
job ever completed. In 2002, Trenchless Technology recognized
the project as an Honorable Mention in Project of The Year Competition
for New Installation. |
