CJA’s team has constructed cantilevered, anchored with tiebacks, and internally braced soldier pile walls throughout the West Coast for a wide range of projects. Soldier pile walls can be permanent or temporary in nature and are commonly used to support open excavations next to adjacent roads, utilities, and structures, and to provide permanent support for new highway cuts or existing land slide conditions.
Soldier pile walls consist of wide flange steel piles that are driven or drilled into the ground 6 to 8 feet apart along the wall alignment before excavation begins. As the excavation progresses, horizontal timber lagging is installed between the piles in 5 foot “lifts” to resist the load of the retained soil and transfers the load to the piles. Depending on the depth of the excavation and the sensitivity of surrounding structures and utilities to movement, Post-tensioned anchors and/or internal bracing can then be installed at intervals to provide lateral support to the solider beams. The lagging “lift” and excavation cycle continues until the bottom of excavation depth is reached.
Soldier pile walls can be either temporary or permanent. Pre-cast lagging can also be used instead of wood for a longer service life with corrosion protection added to the beam and anchors.
CJA offers a variety of services related to soldier pile walls such as design/build services, construction, permanent shotcrete facing, and shotcrete sculpting for a “natural stone” appearance. Feel free to contact us to see what we can do for you.
