The present invention attempts to provide users of industrial explosives, particularly in the bank-blasting sector (quarries, mines, public works, etc.), with a useful, flexible and economical technical solution that solves the problem of removing water from bores. The invention describes the design and operation of a water-extraction pump based on the principle of pneumatic displacement, which uses, as an essential part, alternating intake and delivery cycles in order to provide the necessary operational performance level for the drainage process. Given its inventive design, with an exterior profile that has no appreciable projections, it will make it possible to minimize blockage problems as much as possible.
L'invention concerne une pompe d'épuisement de trous de tarière au moyen de cycles alternants d'aspiration et d'expulsion, basée sur le principe du déplacement pneumatique. Cette pompe comprend un tuyau principal (1) sans saillies que l'on introduit dans le trou de tarière et un tuyau intérieur (6) que l'on introduit dans le tuyau principal. L'extrémité supérieure du tuyau principal reste en surface et présente une fermeture (2) hermétique comportant une prise d'eau (5) raccordée au tuyau intérieur (6) et une prise d'air (4) raccordée en alternance à une source de vide pendant l'aspiration et à une source d'air comprimé pendant l'expulsion. L'invention trouve une application dans la réalisation d'explosions.
