 TM 55-1905-223-SDC
notched at the end to fit against other shores, but this method should not be used if any great pressure is to
be expected. A safer method is to cut a socket in the side of one shore and fit the butt of the other shore into
the socket. This method is shown in FIGURE 7-5.
7-11. SHORING BULKHEADS. Most shoring of bulkheads is done to support bulkheads which are
endangered by structural damage or weakness caused by the pressure of flooding water. Methods of shoring
bulkheads are shown in FIGURES 7-6, 7-7, and 7-8. Observe the following when shoring bulkheads:
a. Allow a large margin of safety in number of shores used.
b. Spread pressure. Make full use of strength members by anchoring shores against beams, stringers,
frames, stiffeners, and stanchions. Place legs of shoring against strongback at an angle of 45 degrees or 90
degrees if at all possible.
c. Do not attempt to force a warped, sprung, or bulged bulkhead back into place. Place shoring so that
it will hold bulkhead in its warped or bulged position.
d. Strengthen main shores, when possible, with auxiliary shores, as shown in FIGURE 7-8. Notice
that strength members A, B, C, and D have been locked in place with auxiliary shores E and F to keep them
from jumping out as the ship works in the seaway. Cleats H and J hold E in place.
