Abstract

Dispositif hydraulique permettant à distance, d'exercer une poussée sur deux plaques opposéee, de mesurer cette poussée et le déplacement des plaques. Il comprend une pompe hydraulique 1 qui commande un vérin volumétrique 3. Ce dernier, d'un côté envoie de l'huile sous pression par une tubulure 10 à des vérins 14 du bloc de poussée pour déplcacer les plaques 20-21, de l'autre, par l'intermédiaire d'une tige 4 à index 5, indique le déplacement des plaques sur un Vernier 6. C'est le volume d'huile injecté qui est utilisé pour traduire le déplacement des plaques. Un manomètre 9 indique la pression exercée sur les plaques. La pompe commande également un vérin 11 de section identique au vérin 3 pour maintenir dans la tubulure 12 une pression extérieure sur la tubulure 10 égale à la pression intérieure de celle-ci évitant ainsi sa déformation parasite. L'invention peut être utilisée, en mécanique des sols, pour mesurer la force portante et les tassements, pour la commande et la mesure des déplacements de vérins classiques.
