All You Need to Know about King Post Walls

One of the oldest forms of soil retaining systems in deep excavations is the king post wall or soldier pile. King post walls have been in use since the late 18th century and have been used successfully in London, Berlin, and New York.

A king post wall is effective when installed in various ground conditions. Usually, it is used in basement construction, embankment retention, and flood defence. The system comprises steel beams or columns, which are the king posts. The posts are installed one or three metres apart, filling the space between the columns or posts with precast concrete panels. Its design must follow Eurocode 7 (geotechnical design) or British standards. 

Installation of King Posts 

The installation of a king post retaining wall includes drilling holes with a high-powered continuous flight auger drilling (CFA) or a mini or large-diameter piling rig. Construction experts will later fill the gap between the posts with concrete. Next, they will install the H-beam, which allows the insertion or installation of the precast concrete panels in between the webs of the H-sections. After finishing the excavation, the construction workers will finish and embed the wall.
