Abstract

The invention makes it possible to form the hollow augers with two concentric tubes, with an annular space making it possible to house instruments for monitoring and measuring the flow rate/pressure of the concrete. By making the internal pipe removable, it enables the concrete passage to be easily cleaned. Application to bored piles cast in the ground by means of a hollow auger.

Description

La presente invention concerne un tubage interieur amovible pour tariere creuse, destinée au moulage des pieux fores. The present invention relates to a removable inner casing for hollow auger, intended for molding bored piles.

Il existe jusqu'à present, des tarieres creuses a un seul tube ou à deux tubes concentriques solidaires, ce qui presente plusieurs inconvenients - nettoyage difficile du passage central qui est souvent obture par des
plaquettes de beton ayant adhere sur les parois, - impossibilité de loger des appareils de controle de pression et debit
de béton dans la tariere.Until now, hollow augers with a single tube or two concentric integral tubes exist, which presents several drawbacks - difficult cleaning of the central passage which is often closed by
concrete plates adhered to the walls, - impossibility of housing pressure and flow control devices
of concrete in the auger.

Dans la presente invention, la tariére ne possede pas un seul tube, mais deux tubes concentriques, avec la particularite pour le tube interieur, de constituer une gaine amovible, ce qui a pour avantage de permettre - un remplacement rapide et peu coüteux de la gaine interieure, lorsque
le passage est obstrue par des plaques de beton, - la mise en place dans l'espace annulaire, de capteurs de pression et de
débit à ltemplacement juge adequat et facilement accessible, - le choix d'un diamétre de passage du béton correspondant à son debit.In the present invention, the auger does not have a single tube, but two concentric tubes, with the peculiarity for the inner tube, of constituting a removable sheath, which has the advantage of allowing - a quick and inexpensive replacement of the sheath interior, when
the passage is obstructed by concrete plates, - the installation in the annular space, of pressure sensors and
flow at the location considered adequate and easily accessible, - the choice of a diameter for the passage of the concrete corresponding to its flow.

D'autres caractéristiques et avantages de l'invention apparaissent à la lecture de la description detaillee qui suit et qui est faite en référence aux dessins annexes dans lesquels - la figure 1 represente une coupe transversale selon la ligne I-II - la figure 2 represente une coupe transversale selon la ligne IIT-IV - la figure 3 représente une coupe longitudinale selon la ligne V-VI
A la figure 7, on trouve representés - le tube exterieur 1 portant les pales assemblées 6 par soudure electri
que sur la paroi extérieure, - les entretoises 2 fixées sur la paroi exterieure, ayant une épaisseur
correspondant à celle de l'espace annulaire, - la gaine intérieure 3 qui est glissée entre les entretoises et mainte
nue par celles-ci pour enserrer l'espace annulaire 4
A la figure 2, on voit le mëme tube extérieur 1 mais l'espace annulaire ~4 est, sur cet emplacement, occupe par l'appareillage électronique de mesures 5.Other characteristics and advantages of the invention appear on reading the detailed description which follows and which is made with reference to the accompanying drawings in which - FIG. 1 represents a cross section along the line I-II - FIG. 2 represents a cross section along the line IIT-IV - Figure 3 shows a longitudinal section along the line V-VI
In Figure 7, there are shown - the outer tube 1 carrying the assembled blades 6 by electric welding
as on the outer wall, - the spacers 2 fixed on the outer wall, having a thickness
corresponding to that of the annular space, - the inner sheath 3 which is slid between the spacers and many
naked by them to enclose the annular space 4
In FIG. 2, we can see the same outer tube 1 but the annular space ~ 4 is, in this location, occupied by the electronic measuring equipment 5.

A la figure 3, se trouve représenté', un élement de tariére composé du tube extérieur 1 portant les pales 6 à l'extérieur et les entretoises 2 sur la face intérieure, puis la gaine intérieure 3. In FIG. 3, there is shown ', an auger element composed of the outer tube 1 carrying the blades 6 on the outside and the spacers 2 on the inner face, then the inner sheath 3.

Ces trois éléments délimitent l'espace annulaire 4 qui est occupé en 5 par l'appareillage électronique de mesures. Pour clore l'espace annulaire 4 a chaque extremite de l'element de tariere, il est dispose deux anneaux 7 et 8, portant sur leur face interieure, une rainure 9 qui s'emboite sur la gaine et possedant sur leur face exterieure, un profil correspondant au systeme d'assemblage adopté pour la tariere. These three elements delimit the annular space 4 which is occupied at 5 by the electronic measuring equipment. To close the annular space 4 at each end of the auger element, there are two rings 7 and 8, carrying on their inner face, a groove 9 which fits on the sheath and having on their outer face, a profile corresponding to the assembly system adopted for the auger.

L'anneau 7 est amovible par coulissement coaxial, pour permettre d'extraire la gaine 3 et degager les appareillages 5. Il est maintenu en position adéquate sur le tube 1, soit a l'aide d'un jonc circulaire 10, soit par boulonnage. The ring 7 is removable by coaxial sliding, to allow the sheath 3 to be extracted and the apparatuses to be released 5. It is maintained in an adequate position on the tube 1, either by means of a circular rod 10, or by bolting .

Pour faciliter son extraction, la gaine 3 est rendue solidaire de l'anneau 7 par collage dans la rainure 9. To facilitate its extraction, the sheath 3 is made integral with the ring 7 by gluing in the groove 9.

L'anneau 8 est fixe et solidaire par filetage ou soudure sur le tube 1, selon la facilité d'usage. The ring 8 is fixed and secured by threading or welding on the tube 1, according to the ease of use.

Les anneaux 7 et 8 sont en outre, perces pour permettre le pas- sage de conduits ou de cables electriques.  The rings 7 and 8 are furthermore drilled to allow the passage of conduits or electric cables.
