Once on site, piles should be suppoxted by placing twe supports only
between the pile and the ground. As described above, “two-peint'’ support best
guarantees control ever the loads and thus the resulting pile stresses. Althsugh
there should be negligible dynamic effects whilst the piles are being stored,
the act of placing and lifting may create some dynamic effect.

Each support should be located as close to (0.2 x pile length) in from
each end, as much as is possible. This arrangement balances the stresses in the
pile at the support leeations with the stresses around the mid-span area, as
best as pessible. This is the preferred arrangement for all piles.

Self weight is assumed to be ‘thé only load acting on the pile, although
piles may be stacked on top of each ether provided that the eupport bearers are

used as described above.

Piles of different lengths should be kept in different stacks. If this is
unavoidable, the bearer locations described in Table 2 may be considered as

“allowable extreme! values.

Notes

1. “A' = overhang distance from an end of the pile to the closest support

bearer.
“B' = distance between support bearers.

2. A’ and “B' axe not necessarily concurrent,

: se ~~ = a+ .
3, The minimum overhang distance for all piles is 1.0m.

4. The bearers will be as required above.
