Patent

CA 2678446

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.

Dans un exemple d'application, la présente invention inclut une pluralité de palplanches individuelles courbes qui sont placées sous un canal, comme une canalisation, pour soutenir un conduit pendant l'excavation. Dans un exemple d'application, les sections individuelles de palplanches courbes sont adaptées et /ou interreliées. Ceci permet aux sections individuelles de travailler en combinaison les unes avec les autres pour soutenir le conduit. Plus précisément, les extrémités opposés d'une longueur de palplanches courbes adaptées et/ou interreliées s'étendent dans du terrain non excavé des deux côtés d'une tranchée excavée pour former un pont au-dessus du trou, qui soutient le conduit et tout sol ou matériau souterrain se trouvant au-dessus de la palplanche courbe.
