Abstract

La présente invention concerne un procédé de construction à des fins de clouage au sol caractérisé en ce qu'il comporte : une étape consistant à fabriquer un élément de renforcement expansible (100) conçu à des fins d'expansion quand un fluide hydraulique pénètre dans l'espace creux interne de celui-ci ; une étape d'alésage consistant à former un trou alésé (1) dans une surface inclinée ; une étape d'incorporation consistant à incorporer l'élément de renforcement expansible (100) dans le trou alésé (1) ; une étape d'expansion consistant à introduire un fluide hydraulique dans l'espace creux de l'élément de renforcement expansible (100) à des fins d'expansion de celui-ci ; une étape de coupe consistant à couper l'extrémité avant de l'élément de renforcement expansible (100) qui est étendu de façon à former une partie ouverte découpée (101) ; et une étape de renforcement consistant à former une structure combinée d'un noyau (150) et d'un coulis (G) pour l'espace creux de l'élément de renforcement expansible (100) de la partie ouverte découpée (101). Ainsi l'affaissement d'une surface inclinée lors de la construction est en mesure d'être évité, et une structure de renforcement plus sûre de la surface inclinée peut être obtenue.
