Abstract
In one exemplary embodiment, the present invention includes a plurality of individual curved sheet piles that are positioned beneath an underground conduit, such as a raceway, to support the conduit during excavation. In one exemplary embodiment, the individual sections of curved sheet pile are interfit and/or interconnected. This allows the individual sections to work in combination with one another to support the conduit. Specifically, opposing ends of a length of interfit and/or interconnected curved sheet piles extend into unexcavated soil on both sides of an excavated hole to form a bridge across the hole that supports the conduit and any soil or other subterranean material positioned above the curved sheet pile.
