Abstract

L'invention concerne une tête d'aspiration de liquide dans un forage et/ou une cavité souterraine comprenant : - un corps de guidage (2) comprenant des moyens (3) de fixation à un système de suspension, - des moyens (7) de raccordement à un tube (8) d'évacuation de liquide, - un flotteur suiveur (10) mobile en translation le long d'une partie au moins du corps de guidage (2) et pourvu d'une crépine d'aspiration (12), - un tube souple suiveur (15) raccordé, d'une part, à la crépine d'aspiration (12) du flotteur suiveur (10) et, d'autre part, aux moyens de raccordement (7), - des moyens (20) de reprise du mou du tube suiveur (15) comprenant au moins une poulie (21) mobile par rapport au corps de guidage (2) et des moyens de rappel (25) adaptés pour exercer sur la poulie une force de rappel (Fr) opposée à la traction (Ft) exercée par le tube suiveur (15) lors de l'immersion du flotteur suiveur (10). L'invention concerne aussi un procédé d'aspiration d'un liquide situé en surface d'une nappe d'eau souterraine, consistant à immerger, en partie au moins, au moins une telle tête d'aspiration au niveau de l'interface (I) entre l'eau et le liquide à aspirer, les moyens de rappel (25) de chaque tête d'aspiration étant adaptés pour permettre au flotteur suiveur (10) de suivre la variation du niveau de la nappe d'eau souterraine en maintenant la crépine d'aspiration (12) au niveau de l'interface entre l'eau et le liquide à aspirer ou au dessus de cette interface.The invention relates to a suction head of liquid in a borehole and / or an underground cavity comprising: - a guide body (2) comprising means (3) for fixing to a suspension system, - means (7) for connecting to a tube (8) for discharging liquid, - a follower float (10) movable in translation along at least a portion of the guide body (2) and provided with a suction strainer (12). ), a flexible follower tube (15) connected, on the one hand, to the suction strainer (12) of the follower float (10) and, on the other hand, to the connection means (7), - means (20) for recovering the slack of the follower tube (15) comprising at least one pulley (21) movable relative to the guide body (2) and return means (25) adapted to exert on the pulley a restoring force ( Fr) opposite the traction (Ft) exerted by the follower tube (15) during the immersion of the follower float (10). The invention also relates to a method of suctioning a liquid located on the surface of a groundwater layer, comprising immersing, at least in part, at least one such suction head at the interface ( I) between the water and the liquid to be sucked, the return means (25) of each suction head being adapted to allow the follower float (10) to follow the variation of the level of the groundwater table while maintaining the suction strainer (12) at the interface between the water and the liquid to be aspirated or above this interface.
