HZ combined walls

The HZ wall is a combined system incorporating:

• HZ king piles as structural supports
• double AZ sheet piles as intermediate elements

Systemwise assembly of these basic elements yields a full range of standard solutions.

Structurally, the HZ primary piles fulfill two different functions:

• as retaining members, they resist horizontal loads resulting from earth and hydrostatic pressures
• as bearing piles, they transfer vertical loads into the ground.

The intermediate sheet piles have only an earth-retaining and load-transfer function and they may be shorter than the HZ primary piles.

The range of sectional combinations of the HZ System is characterized by loadings which can not be covered by conventional sheet piling. Depending on the structural combination and grade of steel adopted, bending moments up to 9000 kNm/m can be safely resisted.
The outstanding feature of this combination is the extensive range of possible combinations using the entire AZ sheet pile offer.
