Abstract

L'invention concerne un système d'échafaudage précontraint innovateur utilisant des supports d'éléments de mise sous tension triangulaires et des éléments de mise sous tension au lieu d'une pluralité d'entretoises destinées à supporter la poussée d'éthers exercée pendant les travaux de terrassement ou une structure de construction souterraine, éliminant ainsi les obstacles de la construction, notamment les pieux ou entretoises intermédiaires et contribuant à améliorer l'efficacité de la construction de l'espace souterrain tout en réduisant les coûts de construction.
