Definitions
- the invention relates to an anchor of the type comprising a longitudinal reinforcement, one end of which is sunk into the ground and sealed to the ground by a hardened mass of a sealing grout and the opposite end of which is stressed by traction means to prestress the tie rod.
- the present invention aims to facilitate the extraction of the frame.
- the frame is for example constituted by a bar or a bundle of strands.
- the sealing tube is advantageously a glass fiber tube which ensures the continuity of the sealing between the reinforcement and the ground and thus, ensures the transition of the tensile force from the tie rod to the ground during the service phase.
- the tensile force of the tie passes from the frame to the glass fiber tube by overlapping, putting in traction the latter by a value close to that of the force applied in the frame.
- the tensile force exerted on the glass fiber tube is then diffused in the ground by the sealing bulb created around the tube.
- the glass fiber tube is thus the weak link in a sealing chain whose continuity can be broken by the destruction of the material of which it is composed.
- the reinforcement is dimensioned so that the value of the tensile strength of the reinforcement is greater than that of the glass fiber tube.
- the glass fiber tube 2 was fixed to the reinforcement 6 before the introduction of the tube and the reinforcement into the borehole.
- the grout for fixing the tube to the ground can no longer be introduced from inside the tube and it is introduced by an injection tube 9 outside the tube 2.
- the glass fiber tube is replaced by plastic tubes having equivalent properties for the use considered.

Abstract
Description
L'invention concerne un tirant d'ancrage du type comprenant une armature longitudinale dont une extrémité est enfoncée dans le terrain et scellée au terrain par une masse durcie d'un coulis de scellement et dont l'extrémité opposée est sollicitée par des moyens de traction pour précontraindre le tirant.The invention relates to an anchor of the type comprising a longitudinal reinforcement, one end of which is sunk into the ground and sealed to the ground by a hardened mass of a sealing grout and the opposite end of which is stressed by traction means to prestress the tie rod.
Lorsqu'il s'agit d'un tirant utilisé de façon temporaire, il est avantageux de pouvoir retirer l'armature après service pour éviter qu'elle ne constitue une gêne dans le terrain et / ou pour la réutiliser.In the case of a tie rod used temporarily, it is advantageous to be able to remove the reinforcement after service to prevent it from causing discomfort in the ground and / or to reuse it.
La présente invention vise à faciliter l'extraction de l'armature.The present invention aims to facilitate the extraction of the frame.
On y parvient selon l'invention en incorporant au coulis de scellement avant sa prise un tube entourant l'armature, ce tube étant apte à résister à la traction de précontrainte mais à être rompu par une traction exercée sur l'armature supérieure à la traction de précontrainte mais insuffisante pour rompre l'armature.This is achieved according to the invention by incorporating into the sealing grout before it takes a tube surrounding the reinforcement, this tube being able to resist the prestressing traction but to be broken by a traction exerted on the reinforcement greater than the traction prestressing but insufficient to break the reinforcement.
Cela étant, on peut précontraindre l'armature sans danger pour le tube et on peut, si on le désire, tirer sur l'armature avec une force suffisante pour provoquer la rupture du tube et la libération de l'armature qui peut alors être extraite du terrain, du fait que le tube qui la liait au terrain a été rompu.This being so, one can prestress the armature without danger to the tube and one can, if desired, pull on the armature with sufficient force to cause the rupture of the tube and the release of the armature which can then be extracted. of the ground, because the tube which connected it to the ground was broken.
L'armature est par exemple constituée par une barre ou un faisceau de torons.The frame is for example constituted by a bar or a bundle of strands.
Le tube de scellement est avantageusement un tube en fibres de verre qui permet d'assurer la continuité du scellement entre l'armature et le terrain et ainsi, assurer la transition de l'effort de traction du tirant au terrain pendant la phase de service.The sealing tube is advantageously a glass fiber tube which ensures the continuity of the sealing between the reinforcement and the ground and thus, ensures the transition of the tensile force from the tie rod to the ground during the service phase.
L'effort de traction du tirant passe de l'armature au tube en fibres de verre par recouvrement, mettant en traction ce dernier d'une valeur voisine à celle de l'effort appliqué dans l'armature.The tensile force of the tie passes from the frame to the glass fiber tube by overlapping, putting in traction the latter by a value close to that of the force applied in the frame.
L'effort de traction exercé sur le tube en fibres de verre est diffusé par la suite dans le terrain par le bulbe de scellement créé autour du tube.The tensile force exerted on the glass fiber tube is then diffused in the ground by the sealing bulb created around the tube.
Le tube en fibres de verre est ainsi le maillon faible d'une chaîne de scellement dont la continuité peut être rompue par la destruction du matériau dont il est composé.The glass fiber tube is thus the weak link in a sealing chain whose continuity can be broken by the destruction of the material of which it is composed.
Lorsque le tirant n'est plus en service il suffit de surtendre l'armature du tirant pour atteindre la traction de rupture du tube de scellement en fibres de verre et, à la suite de la rupture, d'extraire par traction cette armature. Seuls restent dans le terrain, une fois l'opération terminée, le tube en fibres de verre désintégré et le coulis de scellement placé à l'extérieur de ce dernier.When the tie rod is no longer in service, it suffices to over-tension the reinforcement of the tie rod to reach the breaking tensile strength of the glass fiber sealing tube and, following the rupture, to extract this reinforcement by traction. Only remain in the ground, once the operation is complete, the disintegrated glass fiber tube and the grout placed outside of the latter.
L'armature est dimensionnée pour que la valeur de la traction de rupture de l'armature soit supérieure à celle du tube en fibres de verre.The reinforcement is dimensioned so that the value of the tensile strength of the reinforcement is greater than that of the glass fiber tube.
Les deux figures du dessin joint illustrent deux modes de réalisation de l'invention, en coupe axiale.The two figures of the accompanying drawing illustrate two embodiments of the invention, in axial section.
En référence à ces deux figures, on décrira ci-après les phases de réalisation qui permettent la mise en place d'un tirant, conformément à la présente invention.With reference to these two figures, the production phases which allow the installation of a tie rod will be described below, in accordance with the present invention.
On réalise les opérations suivantes :
- on réalise dans le terrain un
forage 1 ayant la longueur voulue pour l'ancrage ; - on met en place dans ce forage un
tube 2 en fibres de verre, sur tout ou partie de la longueur du forage. En fait, ce tube n'est nécessaire que dans la région prévue pour le scellement au terrain de l'extrémité inférieure de l'armature du tirant. Dans l'exemple considéré, le tube en fibres de verre ne s'étend pas sur toute la longueur du forage mais seulement sur la partie inférieure du forage et il est prolongé vers le haut par un tube deprotection 3 ; - on injecte un coulis de ciment dans le
tube 2 en sorte que ce coulis traverse le tube par une série demanchettes 4 et remplisse l'espace 5 compris entre le tube et le forage. - avant cette injection ou avant que le coulis n'ait fait sa prise, on enfonce l'armature 6 dans le
forage 1 jusqu'à ce que l'extrémité inférieure 6a de l'armature ait pénétrée dans letube 2 sur une longueur suffisante. Le coulis d'injection assure d'une part la fixation dutube 2 à la paroi du forage et, d'autre part, la fixation de l'armature à ce tube, en sorte que tout se passe comme si l'armature était fixée au forage par l'intermédiaire d'un bloc de ciment comportant autour de l'armature un cylindre de moindre résistance à la traction constitué par le tube en fibres de verre. On met en place autour de l'autreextrémité 6b de l'armature, un dispositif de précontrainte traditionnel constitué, par exemple par une plaque de répartition 7 appuyée sur le terrain et un écrou 8 coopérant avec une partie filetée de cette extrémité.
- a
borehole 1 is made in the ground having the desired length for anchoring; - a
tube 2 made of glass fibers is placed in this borehole over all or part of the length of the borehole. In fact, this tube is only necessary in the region provided for sealing the terrain of the lower end of the frame of the tie rod. In the example considered, the glass fiber tube does not extend over the entire length of the borehole but only over the lower part of the borehole and is extended upwards by aprotective tube 3; - a cement grout is injected into the
tube 2 so that this grout passes through the tube through a series ofsleeves 4 and fills thespace 5 between the tube and the borehole. - before this injection or before the grout has set, the
frame 6 is driven into theborehole 1 until thelower end 6a of the frame has penetrated into thetube 2 over a sufficient length. The injection grout ensures on the one hand the fixing of thetube 2 to the wall of the borehole and, on the other hand, the fixing of the reinforcement to this tube, so that everything happens as if the reinforcement was fixed during drilling by means of a cement block comprising around the reinforcement a cylinder of least resistance to the tension constituted by the glass fiber tube. Is put around around theother end 6b of the frame, a traditional prestressing device consisting, for example by a distribution plate 7 supported on the ground and a nut 8 cooperating with a threaded part of this end.
Dans la variante de la figure 2, le tube en fibres de verre 2 a été fixé à l'armature 6 préalablement à l'introduction du tube et de l'armature dans le forage. Dans ce cas, le coulis de scellement pour fixer le tube au terrain ne peut plus être introduit par l'intérieur du tube et il est introduit par un tube d'injection 9 extérieur au tube 2.In the variant of FIG. 2, the
Dans des variantes, on remplace le tube en fibres de verre par des tubes en matière synthétique ayant des propriétés équivalentes pour l'usage considéré.In variants, the glass fiber tube is replaced by plastic tubes having equivalent properties for the use considered.
