Abstract
Description
Système de nettoyage des tarières utilisées en fondation spéciales.Auger cleaning system used in special foundations.
- L'utilisation des vis d'Archimède pour le forage des trous de fondation est de plus en plus répandu,parallelement le diamètre et la longueur des vis ou tarières ne cesse d'auggenter . Le problème du nettoyage se pose au moment de l'extraction de la vis après exécution du forage. A ce jour , ce travail s'effectue par l'intermédiaire de plusieurs ouvriers armés de pelles et de pioches qui ,souvent , n'arrivent pas a étaler la vitesse de remontée de l'outil et de nombreux blocs restent coincés entre les pales de la tarière. C'est pour palier a ces divers inconvénients que nous avons mis au point un système semi automatique de nettoyage.- The use of Archimedes' screws for drilling foundation holes is more and more widespread, at the same time the diameter and the length of the screws or augers is constantly increasing. The cleaning problem arises when the screw is extracted after drilling has been completed. To date, this work is carried out by the intermediary of several workers armed with shovels and picks, who often do not manage to spread the tool's ascent rate and many blocks remain trapped between the blades. the auger. It is to overcome these various drawbacks that we have developed a semi-automatic cleaning system.
- Celui-ci consiste dans l'utilisation d'une petite tarière courte (1) d'environ 40 à 70 cm de longueur montée au bout d'un axe (2) maintenu sensiblement hori- zontal grace a un " Y " de suspension (3)et mu en rotation par un moteur pneumatique ,hydraulique ,electrique ou autre (4) situé à l'autre extrémité de cet axe, l'ensemble est toutefois mobile dans presque toutes les directions grace a un cardan (5) ,l'appareil est suspendu par un système d'équilibre des masses ,contrepoids, (6) évitant ainsi toute fatigue inutile pendant l'utilisation,seule une légère pression sur l'appareil est necessaire pour faire pénétrer la tarière dans les déchets de forage situés sur les pales de l'outil a nettoyer . - Deux poignées permettent au manoeuvre de diriger l'appareil dans la direction souhaitée (7) en outre un contacteur manuel ( 8) lui permet également de controler le sens de rotation ou l'arrêt de l'outil de nettoyage. - This consists of the use of a small short auger (1) of about 40 to 70 cm in length mounted at the end of an axis (2) maintained substantially horizontal thanks to a "Y" of suspension (3) and rotated by a pneumatic, hydraulic, electric or other motor (4) located at the other end of this axis, the assembly is however movable in almost all directions thanks to a gimbal (5), l the device is suspended by a mass balance system, counterweight, (6) thus avoiding any unnecessary fatigue during use, only a slight pressure on the device is necessary to penetrate the auger into the drilling waste located on the blades of the tool to be cleaned. - Two handles allow the maneuver to direct the device in the desired direction (7) in addition a manual switch (8) also allows it to control the direction of rotation or the stopping of the cleaning tool.
