Abstract
Description
L'invention a trait a l'exécution, dans un terrain, d'ouvrages a section annulaire. The invention relates to the execution, in a field, of annular section works.
A titre d'exemple non limitatif, ces ouvrages peuvent être utilisés comme pieux de fondation en béton a noyau creux, où la résistance est concentrée dans la zone périphérique en laissant le terrain intact dans la zone centrale; les pieux de ce genre peuvent offrir,par rapport aux pieux ayant n'importe quelle section, une épargne notable de béton et de temps d'execution. By way of nonlimiting example, these structures can be used as concrete foundation piles with a hollow core, where the resistance is concentrated in the peripheral zone, leaving the ground intact in the central zone; piles of this kind can offer, compared to piles of any cross section, significant savings in concrete and execution time.
Le même système peut être adopté pour réaliser dans le terrain une conduite en béton sans recourir à un creusage préalable pour la mise en place d'un tuyau préfabriqué. The same system can be adopted to make a concrete pipe in the ground without having to dig beforehand for the installation of a prefabricated pipe.
L'equipement est constitué par un tube métallique ayant une longueur correspondant à la longueur de l'ouvrage à réaliser. The equipment consists of a metal tube having a length corresponding to the length of the structure to be produced.
La surface exterieure du tube porte des pas d' hélice saillants correspondant à l'épaisseur du pieu à noyau creux ou du tuyau à réaliser. The outer surface of the tube has protruding propeller pitches corresponding to the thickness of the hollow-core pile or of the pipe to be produced.
Le tube est introduit dans le terrain par rotation, en utilisant l'action de forage de l'hélice formée à sa surface extérieure, et ceci pour toute la hauteur désirée. The tube is introduced into the ground by rotation, using the drilling action of the propeller formed on its outer surface, and this for all the desired height.
Ensuite, le tuyau est extrait et, en même temps (ou aussi successivement si le terrain ne s'effondre pas) le béton est introduit dans le trou creusé. Si nécessaire, une armature peut être introduite, au moyen d'un vibrateur, dans le béton, immédiatement après le coulage de celui-ci. Then, the pipe is extracted and, at the same time (or also successively if the ground does not collapse) the concrete is introduced into the dug hole. If necessary, a reinforcement can be introduced, by means of a vibrator, into the concrete, immediately after it has been poured.
On a aussi prévu la possibilité d'introduire le béton à travers le même équipement de perforation par l'intermédiaire d'une tête tournante d'adduction disposée au sommet du tube de forage. Provision has also been made for the possibility of introducing the concrete through the same perforating equipment by means of a rotating adduction head disposed at the top of the drilling tube.
L'invention serin maintenant mieux comprise d' après l'exemple de réalisation qu a été représenté sur les figures annexées, sur lesquelles
la figure 1 est une vue latérale de l'équipement de forage,
la figure 2 est la vue de la coupe II-II de la figure 1,
les figures 3, 4, 5 sont des vues latérales schématiques des phases opératoires successives.The invention can now be better understood from the embodiment that has been shown in the accompanying figures, in which
FIG. 1 is a side view of the drilling equipment,
FIG. 2 is the view of section II-II of FIG. 1,
Figures 3, 4, 5 are schematic side views of the successive operating phases.
En se rapportant tout d'abord aux figures 1 et 2, on remarquera que l'équipement de forage est composé par un tube de forage (a) sur lequel est aménagé une saillie hélicoTdale (b). Le tube (a) est solidaire de la tige de manoeuvre (c) insérée dans la table de rotation (d). Le béton parvient dans le trou par l'intermédiaire de la tête d'adduction (e). Referring first to Figures 1 and 2, it will be noted that the drilling equipment is composed of a drilling tube (a) on which is arranged a helical projection (b). The tube (a) is integral with the operating rod (c) inserted in the rotation table (d). Concrete enters the hole through the supply head (e).
L'exécution de la structure annulaire proposée se réalise comme suit : le tube pénètre dans le terrain, comme il est dit ci-dessus. On réalise ainsi un trou annulaire (f) (figure 3). Lorsque l'appareil a réalisé un trou de la longueur désirée (figure 4), on commence à extraire le tube (a), tandis que l'on coule dans le trou (f) le béton (g) au moyen de la tête tournante d'adduction (e). Une fois que la coulée est termine (figure 5) on peut introduire une armature (i) par exemple à l'aide d'un vibrateur dans le trou annulaire ainsi comblé de béton. The execution of the proposed annular structure is carried out as follows: the tube penetrates into the ground, as it is said above. This produces an annular hole (f) (Figure 3). When the device has made a hole of the desired length (Figure 4), we begin to extract the tube (a), while we pour the hole (f) the concrete (g) by means of the rotating head of adduction. Once the casting is finished (Figure 5) one can introduce a reinforcement (i) for example using a vibrator in the annular hole thus filled with concrete.
