Apparatus and an associated method for forming a pier in a soil matrix (28) includes a hollow tube (38) with a restricted expansion section (20) connected to and adjacent a soil penetrating bottom head element (22) which is configured to facilitate discharge of pier forming material such as grout. An expansion device (26) in the form of an expandable bladder or expandable mechanical device is positioned along a section of the length of the restricted expansion section (20). The hollow tube structure is inserted into a soil matrix with the expansion device in the retracted condition. Subsequently, the expansion device is expanded to enlarge the formed cavity in the soil matrix. Then grout or other pier forming material is injected into the cavity as the expansion device is retracted or deflated and as the hollow tube structure is raised incrementally to form a pier with one or more uniquely shaped lifts.

L'invention concerne un appareil et un procédé associé de formation d'une jetée dans une matrice de terre. Cet appareil comprend un tube creux doté d'une section d'expansion restreinte reliée et adjacente à un élément de tête inférieure qui pénètre la terre et est configuré de manière à faciliter le déchargement du matériau de formation de jetée tel du coulis. Un dispositif d'extension qui se présente sous la forme d'une vessie extensible ou un dispositif mécanique extensible est disposé le long d'une section de la longueur de la section d'expansion restreinte. La structure de tube creux est insérée dans une matrice de terre, le dispositif d'extension étant en position rétractée. Par le suite, le dispositif d'extension s'étend de manière à élargir la cavité formée dans la matrice de terre. Puis, du coulis ou un autre matériau de formation de jetée est injecté dans la cavité lorsque le dispositif d'extension est rétracté ou dégonflé et lorsque la structure de tube creux augmente progressivement afin de former une jetée avec un ou plusieurs supports de forme unique.
