Backfilling to the bulkhead will then begin. The
first backfilling operation will consist of filling over the
anchorage out to the sloping dotted line. The
turnbuckles on the tie rods will then be set up to bring
the bulkhead plumb. Then the remaining fill, out to the
bulkhead, will be put in. Finally, outside the bulkhead,
the bottom will be dredged to a depth of 30 feet.
As shown in figure 8-36 the fender piles will be
fitted with a timber cap to make it possible for the ships
to come alongside the bulkhead. These piles, installed
at proper intervals, will provide protection against the
impact of ships and will protect the hulls of ships from
Wharfage structures are designed to allow ships to
dock alongside then for loading and discharge. Figure
8-37 shows various plan views of wharfage structures.
Any of these may be constructed of fill material,
supported by bulkheads. However, a pier or marginal
wharf usually consists of a timber, steel, or concrete
superstructure, supported on a substructure of timber,
steel, or concrete pile bents.
Working drawings for advanced-base piers are
contained in the Facilities Planning Guide, vol-
ume 1, NAVFAC P-437. Figures 8-38, 8-39, and
