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.
