Dans tous les cas, le coulis utilisé doit avoir un comportement approchant celui du sol, même s’il n’est pas vraiment possible de faire correspondre leurs caractéristiques parfaitement, en particulier si […]
FAQ#026 – Que peut-on faire lorsque le tube inclinomètre « flotte » et remonte pendant l’installation?
Si le tube, même rempli d’eau, est plus léger que le coulis de ciment injecté, l’effort d’arrachement du coulis varie avec la hauteur de la colonne de coulis. Si la colonne est courte, l’effort d’arrachement est faible et le tubage peut être maintenu en place par son propre poids avec une très petite force vers […]
