Z886 Layout
Upon completion of the excavation, the channel should
be placed in numeric order alongside the excavation
according to the job layout. Each trench section has a
trench identification number and flow direction indicating
its sequence within the system. It is best to work from the
deep or outlet end to the shallow. Grates are not installed
at this time.
Four (4) shipping/installation bars per channel;
recommended spacing is approximately 3"-6" [76-152]
from end of rail for end pieces and 26"-29" [660-737] from
end of rail for center pieces. All shipping/installation bar
locations are approximate.
