16.3. Preparing the Trench and Drainage System
Drainage pipes must be laid at one or both ends of the trench to allow water
to
fl ow either into storm water drains or into any other area away from
the installation. Section 16, Figure 43 shows two recommended drainage
con
fi gurations. Once complete, hold the drainage pipes in place by pouring a
100mm concrete foundation and level o ff .
If the SECTOR II and CLAWS are to be separated, a trench for the conduit and
cables will need to be dug, and the wiring harnesses will need to be extended in
relation to the distance between the gearbox and SECTOR II. This must be done
before any concrete is poured (Section 16.5.2.).
Ensure that the drain pipes will not interfere with the structure when it is in the
trench.
