HZ Combi-wall system, also known as HZM king pile, fulfills two different structural functions: retaining members for soil and hydrostatic pressures and bearing piles for vertical loads. The interlocks are welded to the H king pile to connects the H king pile to the sheet pile. The sheet piles are usually shorter than the H king piles combined together. The king piles are designed to carry substantial vertical loads in addition to the normal bending loads. They are widely used in port constructions and deep foundations because of their high bending resistance and stiffness. The outstanding feature of the HZ Combi-wall system is the extensive range of possible combinations. We can design for our customers according to their requirements.
