Trenchless Installation vs. Open cut
8
•
The longest single drive 930 m
•
Installation advanced with average
speed of 22m, at peak 36m daily,
not imaginable by open-cut.
•
Smooth exterior surface of pipes
(sections 1-3 m, wall thickness
100-117mm, weight 1.9 - 2.5t/m)
assured low friction and with few
exceptions no intermediate stations
were applied
•
Contractor used merely 50% of the
machines’ 18000kN-force capacity.
