BRIDGE ANCHORAGE (Contd)
INTRODUCTION (Contd)
c. Long-Term Anchorage (Contd)
If the IRB will remain for an extended period of time, the transporters (if used)
and BEBs should be replaced with fixed anchorage. Transporters, if used for end
span anchorage, should be replaced with approach guys. Where currents are
0–3 feet/sec (0–0.9 meters/sec), BEBs can be replaced with upstream and
downstream anchorage using shore guys. (Refer to figure 4.) If currents are
3.1–11 feet/sec (1.6–3.4 meters/sec), an overhead cable system must be used. Refer
to Anchorage of Floating Bridges in this work package for assembly and installation
instructions for the various types of fixed anchorage. The components necessary to
install the standard overhead cable system are supplied in the IRB supplemental
set SC-5420-97-CL-E51. Refer to figure 5 for typical bridle line connection to IRB
load receiving pins.
