CHAPTER II, SECTION 3
These stations were reinforced concrete collimating baffles 15° wide and 2’-6” thick with
heights determined by the required elevations
at the top of the baffles. The elevations ranged
from plus 18.0 feet for Station 2260.06 to plus
28.86 feet for Station 2260.01. The working
points of the baffles were required to be at the
center line and on the nearest face of Station
22. Station 2260.01 had two holes and the remaining stations had one hole. Forms for these
stations were prefabricated at Nan. The footing
excavations for Stations 2260.05 and 2260.06
contained as much as 18” of water at high tide.
In pouring these footings, the pour was started
in one corner and continued progressively across
the footing, thus forcing the water ahead of
the concrete.
