Pipe-CRZ Series

Pipe - Sheet Pile Combined Wall System

A Pipe Pile Combination Wall System consists of Steel Pipe Piles that withstand most of the loading and paired Infill ESC-CRZ Sheet Piles that transmit pressure loads to the Pipe Piles. Pipe Piles can range in sizing utilising LSAW, SSAW and ERW Pipes. The Pipe Piles serve two purposes from a structural standpoint, the first being as a retaining member that resists horizontal hydrostatic and earth pressures. The second purpose is to act as a bearing pile, resisting vertical loads. Pipe Pile Combination Walls are generally utilised when a standard series of sheet piles do not have the strength to resist the required design loads. Integration with Tie Back Systems and other anchorages is simple and ESC can offer the full configuration as part of its piling solution package.

Frequently infill sheet piles are not required to be the same length as the king pipe piles – typically between 60 to 100% of the pipe pile length.
