HZ Combined Wall
HZ HZM combined wall systems are combi-wall of king piles and intermediary sheet piling, which are normally used in port construction and deep foundations etc. The HZ type composite pile system consists of H-shaped steel sheet piles and Z-shaped steel sheet piles, which can provide extremely high cross-sectional performance in marine engineering, especially in projects such as ports and docks that require ultra long steel sheet piles.The HZ HZM king piles are formed its shape in mills in length of over 30 meters. HZ HZM combiwall are connector by different connectors, namely RZD16, RZU16, RH16, RZD18, RZU18, RH20. Hot rolled HZ HZM king piles are big H beams with connecting system at both sides. Cold rolled HZ HZM combined walls are welded H beams together with cold formed sheet piles. HZ HZM combi-wall are normally quay wall tied back by a deadman wall or normal sheet piling wall.We have produced and shipped HZ combined walls to many sheet piling projects all over the world
The H-shaped steel sheet pile includes welded H-shaped steel and a locking system.
The HZ type composite wall can be divided into:
1. Double H-shaped steel sheet pile: refers to the connection between H-shaped steel sheet pile and H-shaped steel sheet pile.
2. HZ type composite piles are used in combination with a pair of Z-type steel sheet piles.
3. The combination of double H-shaped steel sheet piles and Z-shaped steel sheet piles is used.
Note: U-shaped or cap shaped steel sheet piles can also be used to replace Z-shaped steel sheet piles in composite walls.
