Description
MUR DE SOUTENEMENT RETAINING WALL
La présente invention concerne les murs de soutènement, c'est-à-dire les éléments de construction destinés principalement à retenir les terres ou les matériaux de remblai, notamment dans les ouvrages routiers.The present invention relates to retaining walls, that is to say construction elements intended mainly to retain earth or backfill material, in particular in road works.
Généralement, de tels murs sont constitués d'une paroi verticale préfabriquée qui repose sur une semelle préfabriquée ou coulée sur place, prenant appui sur le sol.Generally, such walls consist of a prefabricated vertical wall which rests on a prefabricated sole or cast in place, resting on the ground.
Lorsque de tels ouvrages sont réalisés sur des terrains médiocres, il peut apparaître avec le temps des phénomènes de tassement du sol sous la semelle ce qui peut entraîner un basculement de la paroi verticale, celle-ci suivant le mouvement d'affaissement de la semelle, et provoquer ainsi des dégâts importants aux ouvrages. Le mur de soutènement, objet de la présente invention, permet de résoudre ce problème de manière simple et économique.When such works are carried out on mediocre terrain, it may appear over time that the soil subsides under the sole, which can cause the vertical wall to tilt, this following the subsidence movement of the sole, and thus cause significant damage to structures. The retaining wall, object of the present invention, makes it possible to solve this problem in a simple and economical manner.
Plus précisément, l'invention a pour objet un mur de soutènement comprenant une paroi verticale, une semelle apte à prendre appui sur le sol et des moyens de coopération de ladite paroi verticale avec ladite semelle, lesdits moyens de coopération de ladite paroi verticale avec ladite semelle étant constitués par une rotule formée d'une partie mâle et d'une partie femelle appartenant respectivement à l'un et à l'autre des deux éléments constitués par la paroi verticale et la semelle, de telle façon que les deux dits éléments puissent pivoter l'un par rapport à l'autre autour d'au moins un point, lesdits moyens de coopération comprenant en outre des moyens pour empêcher la rotation dans un sens de l'un des deux éléments par rapport à l'autre.More specifically, the subject of the invention is a retaining wall comprising a vertical wall, a sole capable of bearing on the ground and means of cooperation of said vertical wall with said sole, said means of cooperation of said vertical wall with said sole being constituted by a ball joint formed by a male part and a female part belonging respectively to one and the other of the two elements constituted by the vertical wall and the sole, so that the two said elements can pivot relative to each other around at least one point, said cooperation means further comprising means for preventing rotation in one direction of one of the two elements relative to the other.
Les caractéristiques du mur de soutènement de l'invention apparaîtront clairement à la lecture de la description qui suit d'un exemple de réalisation, cet exemple étant donné qu'à titre simplement illustratif et sans aucun caractère limitatif. Cette description est accompagnée de dessins sur lesquels :The characteristics of the retaining wall of the invention will become clear on reading the description which follows of an exemplary embodiment, this example given only by way of illustration and without any limiting character. This description is accompanied by drawings in which:
- la Figure 1 est une vue en perspective éclatée d'un mur de soutènement conçu selon les enseignements de l'invention,FIG. 1 is an exploded perspective view of a retaining wall designed according to the teachings of the invention,
- la Figure 2 est une vue en coupe verticale de ce même mur avec ses éléments en cours d'assemblage, etFIG. 2 is a view in vertical section of this same wall with its elements being assembled, and
- la Figure 3 est une vue en coupe verticale du mur de la Figure 2 montrant la position relative de chacun desdits éléments après tassement du sol.- Figure 3 is a vertical sectional view of the wall of Figure 2 showing the relative position of each of said elements after compaction of the soil.
Les dessins représentant le même mur on se reportera selon le cas à l'une ou l'autre des Figures chaque partie constitutive dudit mur portant les mêmes références sur chacune desdites Figures. Ainsi, comme on peut le voir sur l'ensemble des Figures, le mur de soutènement 1 est formé d'une paroi verticale 2 et d'une semelle 3 prenant appui sur un sol 4.The drawings representing the same wall reference will be made, as the case may be, to one or other of the Figures, each constituent part of said wall bearing the same references on each of said Figures. Thus, as can be seen in all of the Figures, the retaining wall 1 is formed of a vertical wall 2 and of a sole 3 bearing on a ground 4.
Conformément à l'invention, ce mur de soutènement comprend des moyens de coopération de la paroi verticale avec la semelle qui sont constitués par une rotule 5 formée d'une partie mâle 6 réalisée sur la tranche basse 10 de ladite paroi et d'une partie femelle 7 réalisée dans ladite semelle.According to the invention, this retaining wall comprises means for cooperation of the vertical wall with the sole which are constituted by a ball joint 5 formed of a male part 6 produced on the lower edge 10 of said wall and of a part female 7 made in said sole.
Ces parties mâle et femelle sont définies par des surfaces cylindriques 11, 12 de telle sorte que la paroi verticale et la semelle puissent pivoter librement l'une par rapport à l'autre autour d'un point 8 sensiblement situé au centre de la tranche basse 10 de la paroi verticale 2.These male and female parts are defined by cylindrical surfaces 11, 12 so that the vertical wall and the sole can pivot freely relative to each other around a point 8 substantially located in the center of the lower edge. 10 of the vertical wall 2.
Les susdits moyens de coopération sont également constitués par des moyens 9 pour empêcher la rotation dans un sens de l'un des éléments par rapport à l'autre. Ces moyens 9 comprennent une nervure 13 réalisée en déport de ladite paroi verticale 2 et dont l'extrémité distale est munie d'un pied 14 destiné à prendre appui sur la semelle 3. Ainsi qu'on peut l'observer, notamment à la Figure 1, ce pied est constitué par une partie en saillie 15 réalisée en maçonnerie 23, de forme conique pyramidale, formant un emboîtement avec un orifice complémentaire 16 ouvert dans la semelle. On précisera que, bien que l'élément 2 et la nervure 13 soient de préférence préfabriqués en usine, laThe aforementioned cooperation means are also constituted by means 9 for preventing rotation in one direction of one of the elements relative to the other. These means 9 comprise a rib 13 produced offset from said vertical wall 2 and the distal end of which is provided with a foot 14 intended to bear on the sole 3. As can be seen, in particular in FIG. 1, this foot is constituted by a projecting part 15 made of masonry 23, of pyramidal conical shape, forming an interlocking with a complementary orifice 16 open in the sole. It will be noted that, although the element 2 and the rib 13 are preferably prefabricated in the factory, the
FEUÊLLE DΞ REMPLACEMENT partie 23 sera coulée in situ afin de réaliser un emboîtement parfait de la partie saillante 15 du pied 14 dans l'orifice 16.REPLACEMENT SHEET part 23 will be cast in situ in order to achieve perfect nesting of the projecting part 15 of the foot 14 in the orifice 16.
Grâce à la présence des moyens de coopération 9, l'élément constitué par la paroi verticale 2 ne pourra basculer dans le sens dextrorsum lors de sa mise en place sur la semelle 3 et, comme on le verra plus loin, le pied 14 de la nervure 13 pourra aisément se dégager de son logement 16 en cas d'affaissement de la semelle.Thanks to the presence of the cooperation means 9, the element constituted by the vertical wall 2 cannot tilt in the dextrorsum direction when it is placed on the sole 3 and, as will be seen below, the foot 14 of the rib 13 can easily be released from its housing 16 in the event of the sole collapsing.
En effet, le mur selon l'invention comporte des moyens de blocage-déblocage de la nervure 13 avec l'élément constitué par la semelle 3. Ces moyens de blocage-déblocage sont constitués notamment par une percée 17 traversant ladite semelle et se prolongeant au-delà de l'orifice 16.Indeed, the wall according to the invention comprises means for locking-unlocking the rib 13 with the element constituted by the sole 3. These locking-unlocking means are constituted in particular by a breakthrough 17 passing through said sole and extending to the beyond orifice 16.
Bien que les dessins montrent une percée 17 ouverte dans la semelle selon un plan perpendiculaire à celui contenant la paroi verticale 2, cette percée pourra être formée dans un plan parallèle à ce dernier, c'est-à-dire parallèle également au canal 12 de la rotule 5. Comme on peut l'observer à la Figure 2, une goupille amovible 18 est introduite dans cette percée 17 où elle est maintenue par des moyens 20 constitués par une partie écrou 21 réalisée dans la semelle et par une partie filetée correspondante 22 formée sur ladite goupille, cette partie filetée étant ainsi apte à coopérer par vissage avec ladite partie écrou 21. En examinant plus particulièrement les Figures 1 et 2, on constate par ailleurs que le pied 14 de la nervure 13 est muni d'une boucle d'armature 24, réprésentée en traits pointillés, dont les branches sont noyées dans ladite nervure et dont la partie basse émerge afin de venir entourer la goupille 18, cette partie basse étant alors noyée dans la maçonnerie 23 qui sera coulée sur place comme il a été précisé plus haut. Le mur de soutènement de l'invention sera érigé de la manière suivante :Although the drawings show a breakthrough 17 open in the sole in a plane perpendicular to that containing the vertical wall 2, this breakthrough may be formed in a plane parallel to the latter, that is to say also parallel to the channel 12 of the ball joint 5. As can be seen in FIG. 2, a removable pin 18 is introduced into this breakthrough 17 where it is held by means 20 constituted by a nut part 21 produced in the sole and by a corresponding threaded part 22 formed on said pin, this threaded part thus being able to cooperate by screwing with said nut part 21. By examining more particularly Figures 1 and 2, it is further noted that the foot 14 of the rib 13 is provided with a loop d frame 24, shown in dotted lines, the branches of which are embedded in said rib and the lower part of which emerges so as to come and surround the pin 18, this lower part then being embedded ée in masonry 23 which will be poured on site as it was specified above. The retaining wall of the invention will be erected as follows:
Après avoir mis en place la semelle 3 sur le sol 4, on amène en appui l'élément de paroi verticale 2 sur ladite semelle en introduisant d'une part la partie basse de la boucle d'armature 24 dans l'orifice 16 et, d'autre part, la partie mâle 6 de la tranche basse 10 de l'élément 2 dans la partie femelle 7 de la semelle, la jonction des parties mâle 6 etAfter having put in place the sole 3 on the ground 4, the vertical wall element 2 is brought to bear on said sole by introducing on the one hand the lower part of the reinforcement loop 24 into the orifice 16 and, on the other hand, the male part 6 of the lower edge 10 of the element 2 in the female part 7 of the sole, the junction of the male parts 6 and
FEUiLLE DE REMPLACEMENT femelle 7 forme ainsi la rotule 5.REPLACEMENT SHEET female 7 thus forms the patella 5.
On introduit ensuite dans la percée 17, et au travers de la boucle d'armature 24, la goupille 18 et on visse la partie filetée 22 sur la partie écrou 21 (Figure 2).Then introduced into the breakthrough 17, and through the frame loop 24, the pin 18 and the threaded part 22 is screwed onto the nut part 21 (Figure 2).
Une fois cette opération accomplie, on coule la maçonnerie 23 dans l'orifice 16. Après que le remblai ait été formé sur la semelle 3, on extrait la goupille 18 de la percée 17. Le mur est alors définitivement monté.Once this operation has been completed, the masonry 23 is poured into the orifice 16. After the fill has been formed on the sole 3, the pin 18 is extracted from the breakthrough 17. The wall is then definitively mounted.
Par la suite, dans l'hypothèse d'un tassement du sol 4, comme le montre la flèche 25 de la Figure 3, la semelle 3 pourra librement pivoter autour du point 8, le pied 14 de la nervure 13 pouvant se dégager sans contrainte de son logement 16 afin que l'élément de paroi 2 puisse demeurer dans un plan vertical.Subsequently, in the event of soil compaction 4, as shown by arrow 25 in Figure 3, the sole 3 can freely pivot around point 8, the foot 14 of the rib 13 can be released without constraint of its housing 16 so that the wall element 2 can remain in a vertical plane.
