Project Description

Port of Tauranga - Pipe Jack

The sheetpile pit was seven metres by ten metres and was made of eight metres clutched interlocking sheets.

The pit was reinforced with 200 x 400 whaler beams and was dewatered using a six inch vacuum pump and a range of dewatering spears.

The pit was constructed to sit a pipe jacking plant inside. The pipe jacking operation pushed three DN1950 concrete pipes 30 metres under three railway lines.

The sheets were driven using a 35 tonne excavator and a Movax sheet piler.

The pit was excavated using a five tonne excavator.
