CRL C6 Storm water, Auckland

Project Key Features 

• 3 Shafts - 6m dia, 17m deep

• 423m of 2400mm dia concrete pipe

• Double Curved Drive

• Using AVN2400  

A diversion storm water tunnel, lowering the alignment through a section of future works, required a tie into a live storm water pipe. Constructed by a curved alignment pipejacking

The Shaft construction was one secant piles shaft, one caisson which required blasting through an upper layer of basalt and one drilled shaft.

The curved alignment was achieved by using Jack Control equipment ensuring the tight radii could be followed without damaging the pipes
