13. Upon the commencement of work, on each occasion, the stungle, in its passage through
the water, would be deprived
of its proper proportion of cement, for which period the discharge from the shoot
should be conducted to a spot
on the outer part of the berm
where the concrete is not
a
required. After
while,
however, the concrete in the shoot, throughout its submerged length, would become properly charged with cement and a
steady
steady flow of suitable material thereafter follow:
14 Sufficient concrete
should be thus deposited on
the berm outside the toe of
the wall, by moving the shoot
over the area to be grouted, without withdrawing it from the water for each working period, the concrete penetrating the interstices between the upper stratum of stones until they are filled, the process apply.. only to the area of the berm immediately in the front of
the wall, so as to render it state
and capabable of with stand
