coupler is placed on the other end.
The 250-cfm air compressor supplies
pressurized air (80 to 90 psi), forcing the ball through the hose,
displacing any residual water.
b. Once the ball arrives at the receiver, the air compressor is shut
off, pressurized air is release by opening the coupler, and the ball is
removed from the receiver.
c. The hose line is compressed by replacing the ball receiver with an
end cap on the 500-foot hose segment that has just been evacuated.
The
ejector assembly is installed on the pneumatic coupler and connected to the
air compressor.
After 10 minutes of operation the hose line will be
collapsed.
If properly compressed, the pullboards will not be needed to
reflake the hose. The pneumatic coupler and ejector are removed and another
end cap is placed on the hose segment. This hose segment is now ready for
recovery.
2.
Reflaking the hose is accomplished in the reverse order of flaking.
a. A minimum of two trucks with crews of five men each, alternately
recovering hose and unloading the trucks, is recommended for efficient hose
laying.
b. The individual task assignments for each crew member are as follows:
one supervisor, one truck driver, one assistant driver, and two soldiers
reflaking the hose.
The assistant driver is needed to aid the actual
recovery of the hose to the soldiers in the truck who are placing the hose
into the flaking boxes. The assistant driver tells the driver to vary the
speed of the truck according to the speed and needs of the soldiers
reflaking the hose. He also stops the operation if there is a problem with
the hose.
A minimum of two soldiers, one positioned on each side of the
flaking box in the bed of the truck, receive the hose from the assistant
driver. They feed the hose into the flaking box, alternating the fold of
the hose from left to right and then right to left.
