Title (EN) METHOD OF INSTALLING ELECTRODE UNIT FOR BED DETECTION
(FR) METHODE D"INSTALLATION D"UNE UNITE A ELECTRODE POUR LA DETECTION D"UN LIT
Abstract: front page image
(EN)Method of installing an electrode unit in an experimentally drilled hole for bed detection. A coupler (4) is attached to the end of an excavating tube (5) and a non-metallic capsule (2) into which an electrode unit (3) has been inserted is attached to the coupler (4). The tube (5) is inserted into the drilled hole, and the capsule (2) is then separated from the tube (5) at the position for bed detection. The tube (5) is then lifted up from the hole. A bed detection cable (6) is retrieved by winding to pull out the electrode unit (3) from the capsule (2). Since this method inserts and installs the electrode unit while supporting it, it can detect a wider range of beds as compared with the conventional method of hanging it by means of gravity.
(FR)Methode d"installation d"une unite a electrode dans un forage experimental pour detecter un lit. Un coupleur (4) est attache a l"extremite d"un tube d"excavation (5) et une capsule non metallique (2) dans laquelle une unite a electrode a ete introduite est attachee au coupleur (4). Le tube (5) est introduit dans le trou perce, et la capsule (2) est alors separee du tube (5) en position de detection du lit. Le tube (5) est alors remonte du trou. Un cable de detection de lit (6) est remonte par enroulement pour sortir l"unite a electrode (3) de la capsule (2). Etant donne que cette methode assure l"introduction et l"installation de l"unite a electrode tout en la supportant, elle permet de detecter une gamme plus grande de lits en comparaison a la methode conventionnelle ou l"unite a electrode pend par gravite.
