HZ®-M Combinations
A standard HZ-M/AZ combination consists of a king pile (single HZ-M or HZ-M box-pile) and one pair of AZ infill sheet piles.
Combinations C1 and C23 are exceptions: they do not use infill sheet piles.
For instance
HZ-M Combinations - Examples - 12, 26 & C23
Combinations C1 and C23 are exceptions: they do not use infill sheet piles.
For instance
- combination 12: combined wall made of 1 single HZ-M king pile and 2 connectors (Sol. 12) and a double AZ infill sheet per system,
- combination 26: combined wall made of a box-pile with 2 HZ-M king piles and 6 connectors (Sol. 26) and a double AZ infill sheet per system,
- combination C1: steel wall made solely of single HZ-M king piles driven side by side, and linked by 1 RH connector,
- combination C23: steel wall made solely of box-piles HZ-M (box-pile = 2 HZ with 3 RH connectors) driven side by side, and linked by 1 RH connector.
