Hydraulic Jetting

At the start of the 20th century E. M. De Burgh described early uses of two innovations -reinforced concrete, and the use of hydraulic jetting to assist pile sinking. In a design which introduced a new principle for pile protection, the timber piles for a road bridge near Sydney were protected above creek bed level with Monier pipes (in preference to copper or Muntz metal sheathing used up to then) to resist attack by Teredo. A few years later, at Moruya, hollow cast iron piles were fitted with shoe castings which incorporated jet nozzles. A high pressure water pump was connected to the top of the piles, and the resulting jet action was so effective that they had to be restrained against sinking out of control.
