Abstract

The joint is made from a supple material such as rubber and consists of a front wall (5), a rear wall (6) which acts as a trough, and two side walls (8) with flexible lips (9) to engage with the walls of the drainage groove. Each of the lips has a lengthwise edge (19) which is folded towards the rear wall of the joint at an angle of between 60 degrees C and 120 degrees C. The first set of lips from the front wall of the joint is set at a distance from the front wall equivalent to about 40% of the central portion of the joint, while the volume of the joint between the front, rear and side walls is partitioned into air-filled cavities.

Description

La présente invention concerne un joint souple permettant le calfeutrement d'une saignée de drainage aménagée dans une paroi, notamment dans la paroi d'un tunnel.The present invention relates to a flexible seal allowing the caulking of a drainage groove arranged in a wall, in particular in the wall of a tunnel.

Pour éviter les infiltrations d'eau à travers la paroi d'un tunnel, et la formation en cas de gel de stalactites dangereuses pour les véhicules, il est connu d'aménager des saignées transversales dans la paroi du tunnel, d'aménager à partir du fond de ces saignées des forages dans le terrain environnant, pour constituer des drains, et d'insérer dans les saignées des joints profilés en matière souple, présentant une épaisseur inférieure à la profondeur des saignées. Ces joints permettent d'obturer l'ouverture des saignées et de délimiter avec le fond de celles-ci des conduits étanches pour l'écoulement des eaux de drainage. Ces conduits débouchent au-dessus de rigoles d'évacuation aménagées au pied de la paroi du tunnel.To avoid water infiltration through the tunnel wall, and training in case of frost dangerous stalactites for vehicles it is known to make transverse grooves in the wall of the tunnel, to arrange from the bottom of these grooves drilling in the surrounding land, to constitute drains, and insert profiled joints into the grooves in flexible material, having a thickness less than the depth of the grooves. These seals allow to close the opening of the grooves and to delimit with the bottom of these watertight conduits for flow drainage water. These conduits open above evacuation channels arranged at the foot of the wall of the tunnel.

Il existe un joint profilé de ce type comprenant une paroi avant, tournée vers l'intérieur du tunnel après mise en place du joint dans la saignée, une paroi arrière formant gouttière, tournée vers le fond de la saignée après mise en place du joint, deux parois latérales, comprenant des lèvres flexibles qui viennent s'appliquer élastiquement contre les faces délimitant latéralement la saignée pour assurer le maintien du joint dans celle-ci, et deux ailes latérales faisant saillie latéralement de ladite paroi avant, destinées à venir en appui contre la face interne de la paroi du tunnel lorsque le joint est inséré dans la saignée et à recueillir les eaux de condensation ruisselant sur cette face.There is a profiled joint of this type comprising a front wall facing the interior of the tunnel after placing the seal in the groove, a rear wall forming gutter, facing towards the bottom of the groove after fitting the seal, two side walls, comprising flexible lips which are applied elastically against the sides delimiting laterally the groove to ensure the maintenance of the seal therein, and two side wings projecting laterally from said front wall, intended to come into abutment against the inner face of the tunnel wall when the joint is inserted into the bloodletting and to collect the waters of condensation dripping on this face.

La partie centrale du joint, délimitée par lesdites parois avant, arrière et latérales, peut présenter plusieurs voiles internes perpendiculaires les uns aux autres, délimitant une pluralité de chambres longitudinales remplies d'air. Ces chambres, outre un allègement du profilé et un gain en quantité de matière, permettent d'améliorer l'isolation thermique du conduit d'écoulement afin d'éviter la formation de glace dans celui-ci en cas de gel.The central part of the joint, delimited by said front, rear and side walls can present several internal sails perpendicular to them to each other, delimiting a plurality of rooms longitudinal filled with air. These rooms, in addition to a lighter profile and gain in quantity of material, improve the thermal insulation of the duct flow to prevent ice from forming in this in case of frost.

Ce joint existant donne satisfaction en pratique, mais présente toutefois quelques inconvénients, particulièrement dans le cas de parois de tunnels en béton.This existing seal is satisfactory in practice, but has some drawbacks, particularly in the case of tunnel walls in concrete.

En effet, les tolérances dans la largeur des saignées peuvent être importantes, de sorte que les lèvres de maintien d'un joint peuvent être plus ou moins fortement appliquées contre les faces délimitant latéralement la saignée. Une application trop faible de ces lèvres conduit à un maintien insuffisant du joint, et, en cas de débordement du conduit d'écoulement, à des risques de fuite entre ces lèvres et les faces délimitant latéralement la saignée.Indeed, the tolerances in the width of the bleeding can be significant so that the lips holding a joint can be more or less strongly applied against the delimiting faces laterally the bleeding. Too weak an application of these lips leads to insufficient maintenance of the joint, and, in case of overflow of the flow duct, at risk of leakage between these lips and the delimiting faces laterally the bleeding.

De plus, l'angle formé par une face délimitant latéralement la saignée et par la face interne de la paroi du tunnel peut comprendre des "épaufrures", c'est-à-dire peut être rogné ou endommagé sur des portions plus ou moins importantes de la saignée. Lorsque ces épaufrures sont profondes, les lèvres de maintien peuvent s'échapper hors de la saignée par rappel élastique, particulièrement lorsque le joint tend à pivoter dans la saignée et à s'échapper hors de celle-ci, en cas de "désaffleurement". Ce terme désigne un non-alignement des deux parties de la face interne de la paroi du tunnel situées de part et d'autre d'une saignée, ce qui peut se produire lorsque la saignée est aménagée au niveau d'une reprise de bétonnage.In addition, the angle formed by a delimiting face laterally the groove and by the internal face of the wall of the tunnel may include "spallings", that is to say may be cut or damaged on larger portions or less important of the bleeding. When these sprains are deep, holding lips can escape out of the bleeding by elastic return, particularly when the seal tends to pivot in the groove and to escape out of it, in case of "flushing". This term designates a non-alignment of the two parts of the inner face of the tunnel wall located on either side other than a bleeding, which can happen when the bleeding is arranged at the level of a concreting recovery.

Les défauts de positionnement du joint aboutissent à des fuites des eaux de drainage, et donc à la création de stalactites en cas de gel.Joint positioning faults lead to to drainage water leaks, and therefore to the creation stalactites in case of frost.

Un "désaffleurement" peut atteindre deux centimètres et conduit, outre le risque de pivotement précité du joint, à une application défectueuse desdites ailes latérales contre la face interne de la paroi du tunnel. Ces ailes perdent alors leur efficacité.A "mismatch" can reach two centimeters and conducts, in addition to the risk of pivoting above of the seal, to a defective application of said lateral wings against the internal face of the wall of the tunnel. These wings then lose their effectiveness.

La présente invention vise à remédier à ces différents inconvénients.The present invention aims to remedy these different disadvantages.

Le joint qu'elle concerne est du type précité.The seal it relates to is of the aforementioned type.

Selon une caractéristique de l'invention, chaque lèvre de maintien présente, au niveau de son extrémité libre, un rebord longitudinal replié du côté de ladite paroi arrière du joint selon un angle pouvant aller de 60 à 120°.According to a characteristic of the invention, each retaining lip present, at its end free, a longitudinal edge folded back on the side of said rear wall of the joint at an angle of up to 60 at 120 °.

Grâce à cette forme et à la souplesse de la lèvre de maintien, ce rebord vient étroitement s'appliquer contre la face délimitant latéralement la saignée, quelles que soient les variations de largeur possibles de la saignée. De plus, chaque lèvre de maintien aménage une gouttière de captage et d'évacuation de l'eau susceptible de s'infiltrer entre les faces latérales du joint et lesdites faces délimitant latéralement la saignée. La pluralité de rangs de lèvres de maintien que comprend le joint assure ainsi un parfait maintien du joint dans la saignée et une parfaite étanchéité.Thanks to this shape and the flexibility of the lip support, this edge is tightly applied against the side laterally delimiting the bleeding, which whatever the possible width variations of the bleeding. In addition, each retaining lip provides a gutter for collecting and discharging susceptible water to infiltrate between the lateral faces of the joint and said faces laterally delimiting the groove. The plurality of rows of retaining lips that the seal thus ensures perfect retention of the seal in the bleeding and a perfect seal.

Selon une autre caractéristique de l'invention, le rang de lèvres de maintien le plus proche de la paroi avant du joint est situé à une distance de cette paroi supérieure aux plus grandes profondeurs d'"épaufrures" qui peuvent être habituellement observées au niveau de l'angle formé par une face délimitant latéralement la saignée et par la face interne de la paroi du tunnel. Pour un joint classique présentant une partie centrale de forme sensiblement carrée, adapté aux saignées habituelles ayant une largeur de l'ordre de 60 mm, cette distance est au moins égale à environ 40 % de la largeur de cette partie centrale.According to another characteristic of the invention, the row of holding lips closest to the wall front of the seal is located at a distance from this wall greater than the greatest depths of "sprains" which can usually be seen at the angle formed by a side laterally delimiting the groove and by the internal face of the tunnel wall. For a joint classic with a central shape substantially square, suitable for usual bloodletting having a width of the order of 60 mm, this distance is at less than about 40% of the width of this part central.

Il apparaít en effet qu'avec le joint selon la technique antérieure, une épaufrure profonde s'étend au-delà du premier rang de lèvres de maintien que comprend le joint. La lèvre située du côté de cette épaufrure ne peut donc prendre appui contre la face délimitant latéralement la saignée, et la lèvre située sur le côté opposé exerce une contrainte sur la structure du joint, du fait de sa déformation élastique. Cette contrainte conduit à un gauchissement du joint qui est à l'origine du risque précité de pivotement et d'échappement du joint hors de la saignée.It appears indeed that with the joint according to the prior art, a deep sprain extends beyond the first row of holding lips that includes gasket. The lip on the side of this sprain does not can therefore bear against the delimiting face laterally the groove, and the lip located on the side opposite stresses the structure of the joint, the made of its elastic deformation. This constraint leads warping of the joint which is the source of the risk aforementioned pivoting and exhaust of the seal out of the bleeding.

Le joint selon l'invention est dépourvu de lèvres de maintien susceptibles de se trouver en regard d'une épaufrure, ce qui élimine ce risque de pivotement et d'échappement du joint, et donc les fuites qui en résultent.The seal according to the invention is devoid of lips holding likely to be next to a spalling, which eliminates this risk of pivoting and seal exhaust, and therefore the leaks result.

Selon une autre caractéristique de l'invention, les ailes latérales faisant saillie de part et d'autre de la face avant du joint ont une largeur importante, c'est-à-dire au moins égale à la moitié de la largeur de cette face avant.According to another characteristic of the invention, the lateral wings projecting on either side of the front face of the seal have a large width, that is to say at least equal to half the width of this front face.

Ces ailes assurent un large recouvrement d'éventuelles épaufrures, et viennent en contact de la face interne de la paroi du tunnel même en cas de désaffleurements importants. Elles restent ainsi parfaitement efficaces et permettent de constituer des gouttières supplémentaires contribuant à assurer une parfaite étanchéité du joint.These wings provide wide coverage possible spallings, and come into contact with the inner side of the tunnel wall even in case of major outcrops. They stay that way perfectly effective and make it possible to constitute additional gutters helping to ensure perfect seal of the joint.

De préférence, chacune de ces ailes présente une forme de chevron en section transversale, c'est-à-dire comprend deux parties de largeur sensiblement égale formant un angle obtus, de l'ordre de 120°, l'une par rapport à l'autre.Preferably, each of these wings has a chevron shape in cross section, i.e. comprises two parts of substantially equal width forming an obtuse angle, of the order of 120 °, one by compared to each other.

Pour sa bonne compréhension, l'invention est à nouveau décrite ci-dessous en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme de réalisation préférée du joint qu'elle concerne.

  • La figure 1 est une vue en perspective d'une partie de la paroi d'un tunnel équipée de ce joint ;
  • la figure 2 est une vue en perspective d'une partie du joint, et
  • la figure 3 est une vue en coupe transversale du joint inséré dans une saignée.
    • For a good understanding, the invention is again described below with reference to the appended diagrammatic drawing representing, by way of nonlimiting example, a preferred embodiment of the joint which it concerns.
  • Figure 1 is a perspective view of part of the wall of a tunnel equipped with this seal;
  • FIG. 2 is a perspective view of part of the joint, and
  • Figure 3 is a cross-sectional view of the seal inserted in a groove.

    • La figure 1 représente la paroi voûtée 1 d'un tunnel, dans laquelle est aménagée une saignée transversale s'étendant depuis la partie supérieure de cette paroi jusqu'au pied de chacune des parties latérales de celle-ci.Figure 1 shows the vaulted wall 1 of a tunnel, in which a groove is arranged transverse extending from the upper part of this wall to the foot of each of the side parts of it.

    Cette saignée communique avec des forages aménagés dans le terrain environnant pour constituer des drains, et comporte, inséré en elle, un joint profilé 2 en matière souple tel que du caoutchouc. Ce joint 2 permet d'obturer la saignée et de délimiter, avec le fond de celle-ci, un conduit étanche pour l'écoulement des eaux de drainage, ce conduit débouchant au-dessus d'une rigole d'évacuation 3 aménagée au pied de la paroi 1.This bleeding communicates with arranged boreholes in the surrounding land to form drains, and includes, inserted into it, a profiled seal 2 made of flexible such as rubber. This joint 2 allows to close off the bleeding and delimit, with the bottom thereof, a waterproof conduit for drainage water drainage, this duct opening above an evacuation channel 3 fitted at the foot of the wall 1.

    Comme le montrent plus particulièrement les figures 2 et 3, ce joint 2 comprend :

  • - une paroi avant 5, tournée vers l'intérieur du tunnel après mise en place du joint 2 dans la saignée 10,
  • - une paroi arrière 6, tournée vers le fond de la saignée 10 après mise en place du joint 2, comportant deux protubérances latérales triangulaires 7 qui forment, avec cette paroi 6, une gouttière,
  • - deux parois latérales 8, comprenant trois rangs de lèvres flexibles 9 destinées à venir s'appliquer élastiquement contre les faces 11 délimitant latéralement la saignée 10 pour assurer le maintien du joint 2 dans celle-ci,
  • - deux ailes latérales 15 faisant saillie de ladite paroi avant 5, destinées à venir en appui contre la face interne de la paroi 1 lorsque le joint 2 est inséré dans la saignée 10, et
  • - une partie centrale, délimitée par lesdites parois avant 5, arrière 6 et latérales 8, présentant six voiles internes 16 perpendiculaires les uns aux autres, délimitant entre eux et avec lesdites parois 5,6 et 8 une pluralité de chambres longitudinales 17 remplies d'air.
    • As shown more particularly in FIGS. 2 and 3, this joint 2 comprises:
  • a front wall 5, turned towards the inside of the tunnel after fitting the seal 2 in the groove 10,
  • a rear wall 6, facing the bottom of the groove 10 after fitting the seal 2, comprising two triangular lateral protuberances 7 which form, with this wall 6, a gutter,
  • - two side walls 8, comprising three rows of flexible lips 9 intended to be applied elastically against the faces 11 laterally delimiting the groove 10 in order to maintain the seal 2 in it,
  • two lateral wings 15 projecting from said front wall 5, intended to come into abutment against the internal face of the wall 1 when the seal 2 is inserted in the groove 10, and
  • - A central part, delimited by said front 5, rear 6 and side 8 walls, having six internal walls 16 perpendicular to each other, delimiting between them and with said walls 5, 6 and 8 a plurality of longitudinal chambers 17 filled with air.

    • Il apparaít aux figures que chaque lèvre 9 présente, au niveau de son extrémité libre, un rebord longitudinal 19 replié du côté de ladite paroi arrière 6 selon un angle de l'ordre de 90°.It appears in the figures that each lip 9 has a rim at its free end longitudinal 19 folded back on the side of said rear wall 6 at an angle of around 90 °.

    En outre, le rang de lèvres 9 de maintien le plus proche de la paroi avant 5 est situé à une distance de cette paroi 5 égale à environ 40 % de la largeur de ladite partie centrale du joint, de sorte que le joint est dépourvu de lèvres 9 au niveau du voile 16 le plus proche de cette paroi avant 5.In addition, the row of lips 9 holding the most close to the front wall 5 is located at a distance of this wall 5 equal to approximately 40% of the width of said central part of the seal, so that the seal is devoid of lips 9 at the level of the nearest veil 16 of this front wall 5.

    Les ailes latérales 15 ont, quant à elles, une largeur au moins égale à la moitié de celle de cette face avant 5, et présentent une forme de chevron en section transversale, c'est-à-dire comprennent chacune deux parties de largeur sensiblement égale formant un angle de 120° l'une par rapport à l'autre.The lateral wings 15 have, for their part, a width at least equal to half that of this face front 5, and have a chevron shape in section transverse, i.e. each include two parts of substantially equal width forming an angle of 120 ° relative to each other.

    Les rebords 19, grâce à la forme coudée et à la souplesse des lèvres 9, peuvent venir étroitement s'appliquer contre les faces 11 et assurent un parfait maintien du joint 2 dans la saignée 10 quelles que soient les variations de largeur possibles de celle-ci. De plus, les lèvres 9 aménagent des gouttières latérales de captage et d'évacuation de l'eau susceptible de déborder du conduit 20 d'évacuation de l'eau drainée, de sorte que le joint 2 a une parfaite étanchéité.Edges 19, thanks to the angled shape and the flexibility of the lips 9, can come tightly apply against the faces 11 and ensure perfect maintaining the seal 2 in the groove 10 whatever possible width variations thereof. Moreover, the lips 9 arrange lateral collection gutters and discharge of water likely to overflow drain 20 of the drained water, so that the joint 2 has a perfect seal.

    Par ailleurs, grâce à sa distance précitée de la face avant 5, le premier rang de lèvres 9 se trouve situé en retrait d'une épaufrure profonde, telle que celle représentée à la figure 3, lorsque le joint 2 est engagé dans la saignée 10. Le joint 2 ne subit donc aucune contrainte transmise par des lèvres flexibles à hauteur de cette épaufrure, ce qui tendrait à le faire pivoter dans la saignée et à le faire s'échapper hors de celle-ci.Furthermore, thanks to its aforementioned distance from the front face 5, the first row of lips 9 is located set back from a deep spalling, such as that shown in Figure 3, when the seal 2 is engaged in the groove 10. The seal 2 therefore undergoes no stress transmitted by flexible lips up to this spalling, which would tend to rotate it in bleeding and to make it escape out of this one.

    Il apparaít également sur cette figure 3 que les ailes 15 assurent un large recouvrement d'éventuelles épaufrures, et viennent au contact de la face interne de la paroi 1 même en cas de désaffleurements importants. Ces ailes 15 permettent ainsi de constituer des gouttières supplémentaires, contribuant à assurer une parfaite étanchéité du joint 2.It also appears in this figure 3 that the wings 15 ensure a broad covering of possible sprains, and come into contact with the inner side of the wall 1 even in the event of major outcrops. These wings 15 thus make it possible to constitute gutters helping to ensure perfect seal 2.

    Il va de soi que l'invention n'est pas limitée à la forme de réalisation décrite ci-dessus à titre d'exemple mais qu'elle en embrasse, au contraire, toutes les variantes de réalisation. Ainsi, le joint peut comprendre plus ou moins de trois rangs de lèvres 9 et plus ou moins de voiles intérieurs 16, selon ses dimensions, adaptées à celles de la saignée 10 à équiper.It goes without saying that the invention is not limited to the embodiment described above as example but that it embraces, on the contrary, all variant embodiments. So the seal can include more or less than three rows of lips 9 and more or less interior sails 16, according to its dimensions, adapted to those of the groove 10 to be fitted.

    Le joint selon l'invention peut être utilisé non seulement pour calfeutrer des saignées aménagées dans la paroi d'un tunnel, mais également d'éventuelles fissures apparaissant dans celles-ci.The seal according to the invention can be used not only to seal the grooves in the wall of a tunnel, but also possible cracks appearing in them.
