CHAPTER II, SECTION 3
Station 1212.01 pipeline was over the
ocean reef from Station 21 to Pinhole Station
1210.01 located on a man-madeisland off Site
Helen. The pipeline was supported throughout
its length on 8-inch steel piles driven into the
reef at intervals of 30 feet for the 36-inch,
18-inch, and 16-inch pipe sizes, 25 feet for 12-
inch pipe, 20 feet for 8-inch pipe,
for 4-inch pipe. A typical support
one vertical pile with a welded
frame detail at the top of the pile.
and 14 feet
consisted of
angle yoke
Adjustment
of line and grade was accomplished by welded
steel shims to the frame only. Two bellowstype expansion joints were installed in the
12-inch pipe section at approximately the center
of the pipeline length, and one on each side of
a two-pile anchor and support. The endsof the
pipeline were anchored by a two-pile detail at
the first support on Site Gene and at the end
of pipe on the man-made island by embedment of the pipe in the concrete wall of Station
1210.01 with welded slip on square plates
flush against the inner and outer wall surfaces.
The total length of this line was approximately
1500 feet.
Station 1212.02 pipeline ran overland and
over the ocean reef from Station 1211, Irene,
to Pinhole Station 1210.01 on the man-made
island. The pipeline was supported on 8-inch
steel piles at intervals of 30 feet for 36-inch,
30-inch, 24-inch, 20-inch, and 16-inch pipe sizes,
25, feet for 12-inch pipe, 20 feet for 8-inch pipe,
and 14 feet for 4-inch pipe. Typical supports
were the same as for Station 1212.01, except
for the overland piling on Site Irene where the
piling driven into sand was encased in concrete for lateral stability. Three bellows-type
expansion joints were installed in this run of
pipe. The end of the pipeline at Pinhole Sta-
tion 1210.01 was anchored in the same manner
as for Station 1212.01. The opposite end of
the line was anchored at Station 1410, Site
Trene.
The vacuum was produced by vacuum
pumps located in Station
1213 close to the
Site Gene end of theline.
