Title (EN) MACHINE FOR PULLING OUT A DRILLING TUBE OF THE GROUND
(FR) MACHINE POUR EXTRAIRE DU SOL UN TUBE DE FORAGE
Abstract:
(EN) A machine for pulling out a drilling tube for a foundation pile, after concreting, is composed of a tightening collar consisting of several parts (2a to 2f), with a tightening cylinder (9) and a forked base frame. Those of the tightening parts (2c, 2d) which close the opening of the fork of the base frame, can be spaced apart by means of a closing twin-cylinder (16, 17) so that the fork is entirely free and the machine can be set laterally on a working position with respect to the tube. To close the tightening collar, the spaceable tightening parts (2c, 2d) are brought back into position and firmly locked together by means of a locking bolt (24).
(FR) Une machine pour extraire un tube de forage de pieu de fondation apres le betonnage, est composee d"un collier de serrage en plusieurs pieces (2a a 2f) avec cylindres de serrage (9) et d"un cadre de base fourchu. Celles des pieces de serrage (2c, 2d) qui ferment l"ouverture de la fourche du cadre de base, sont ecartables au moyen de doubles cylindres de fermeture (16, 17) de maniere que la fourche soit completement libre et que la machine puisse etre mise lateralement en position de travail par rapport au tube. Pour fermer le collier de serrage les pieces de serrage ecartables (2c, 2d) seront remises en place et verrouillees solidement ensemble par un boulon de verrouillage (24).
