In the field of undergorund piping, pipes are generally thought of as being circular. In this invention, the pipe is not circular in shape: while the bottom half is indeed semicircular in shape, the top half is in the shape of a pointed arch or ogive (see description and drawings). This shape makes it possible to reduce the cylindrical deformation or ovalizing effect caused by pressure exerted by the ground or by vertically-applied pressure.
Dans le domaine de la tuyauterie souterraine, on conçoit que les tuyaux sont de forme circulaire. Dans la présente invention, la forme de la tuyauterie n'est pas circulaire; c'est une demi-circulaire à la base surmontée d'un arc en ogive (voir description, section dessin). Cette forme permet de diminuer l'effet d'ovalisation créé par la force de poussées qu'exerce le sol ou par une pression appliquée de façonverticale.
