AZ SERIES: AZ46


AZ46 was selected as original specification during tender stage. It is because of the large width of steel sheet pile, resulting in good installation performance and good in corrosion resistance, the steel thickest at the critical corrosion points. In addition, consultant Arup reckons AZ46 is very suitable for this project due to their past favorable experience with AZ steel sheet pile for SJM Macau.

Installation Information

PILING MACHINE


To driving AZ46 steel sheet pile length more than 39m, Hydraulic Hammer was selected for pile installation because it is the fastest and effective method of pile installation in order to reach such depth. A debar was weld between the 2 webs (as shown below) to stabilize the width for better splicing and smoother installation.

SHEET PILE HANDLING


Infill sheet crimping was used for vertical splicing. The top part of the steel sheet pile is aligned and crimped, while the toe needs to be trimmed and is flexible to be threaded into the already driven neighboring piles.
