A feature of the construction of the new bridge oyer the Waikato river near Tuakau is the unusual method of driving the piles. The bed of the river is mostly sand and the piles are eacn constructed with a hollow pipe through the centre. A hose is attached to tie top of the pipe and when the pile is in position for driving, water at high pressure is pumped down to the point of the pile. The stream of water blows a bole in the bed of the river to admit the pile, which usually then settles about 13ft down before the pile-driver has to be used. This method is new in New Zealand, but is largely followed in America where piles are to be driven through sand.
