Abstract

La présente invention concerne le matériel utilisé pour la construction des bâtiments et les travaux publics. Le mécanisme comprend un corps cylindrique creux 1 abritant un percuteur à gradins 3 à mouvement axial alternatif ininterrompu. Les gradins du percuteur 3 forment, avec le corps 1, des chambres de travail arrière et avant 4, 5 de volume variable qui communiquent avec une source d'air comprimé et l'air libre. Sur toute la longueur du corps 1, est fixé un tube de guidage 6 abritant une pièce en forme de tige 13 qu'il faut enfoncer. Un canal 7 assure la communication entre la chambre de travail arrière 4 et la chambre de travail avant 5 pour la position avant du percuteur. A la partie avant du corps 1, est rigidement fixé un serre-pièce 12. L'invention s'applique avantageusement à l'enfoncement d'électrodes de mise de terre et d'ancres, pièces en forme de tiges dont la dimension transversale est incommensurablement petite par rapport à la longueur.
