Description
25470 il L'invention concerne la réalisation d'une étanchéité entre desThe invention relates to the realization of a seal between
surfaces en regard de deux éléments surfaces next to two elements
de structure préfabriqués en béton. prefabricated concrete structure.
L'invention s'applique notamment à des struc- The invention applies in particular to structures
tures de pont et à des structures de tunnel et elle sera expliquée en référence à ces deux applications, étant bien entendu que l'invention n'est pas limitée à ces deux bridge structures and tunnel structures and will be explained with reference to these two applications, it being understood that the invention is not limited to these two applications.
applications, comme on le comprendra aisément. applications, as will be easily understood.
Il est connu de réaliser l'étanchéité entre les surfaces en regard de deux voussoirs de pont en appliquant sur toute l'étendue de ces surfaces, immédiatement avant de les rapprocher, un matériau d'étanchéité durcissable à base de résine époxy et d'un durcisseur, le durcissement de ce matériau se faisant par polymérisation, dans les deux ou trois heures qui suivent son application Cette tecl nique exige des soins particuliers du fait que toute l'étenc des surfaces entre lesquelles on veut assurer l'étanchéité doit recevoir l'application et que cette application doit se faire pratiquement au moment de la mise en place des voussoirs en raison de la rapidité de la polymérisation, La présente invention vise à éviter ces inconvénients. Les tunnels immergés sont généralement constitué d'éléments successifs préfabriqués en béton et le problème se pose de réaliser chaque fois l'étanchéité entre deux éléments successifs Une solution connue consiste à fixer une feuille d'étanchéité à l'un des éléments, cette feuille It is known to achieve sealing between the surfaces facing two bridge segments by applying to the entire extent of these surfaces, immediately before bringing them together, a curable sealant based on epoxy resin and a hardener, the hardening of this material is by polymerization, within two or three hours after its application This technique requires special care because all the étenc surfaces between which we want to ensure the seal must receive the This application aims to avoid these disadvantages. The submerged tunnels generally consist of successive prefabricated concrete elements and the problem arises of each time sealing between two successive elements. One known solution consists in fixing a sealing sheet to one of the elements, this sheet

La présente invention vise aussi à éviter ces inconvénients. On y parvient, selon l'invention, en utilisant l'une des surfaces comme moule pour constituer l'autre surface et en utilisant comme matériau d'étanchéité un The present invention also aims to avoid these disadvantages. This is achieved according to the invention by using one of the surfaces as a mold to form the other surface and using as sealing material a
matériau polymérisable et expansif en présence d'eau. polymerizable and expansive material in the presence of water.
Ces deux moyens sont connus mais la présente These two means are known but this
invention les combine pour la première fois. invention combines them for the first time.
Il est connu en effet de préfabriquer chaque élément d'une suite d'éléments de structure en béton par la technique dite des "joints conjugués" qui consiste à utiliser un élément déjà fabriqué comme l'une des extrémités It is known in fact to prefabricate each element of a series of concrete structural elements by the technique known as "conjugated joints" which consists in using an element already manufactured as one of the ends
du moule ou du coffrage servant à la fabrication de l'élé- mold or formwork used in the manufacture of the
ment voisin On obtient ainsi des surfaces dites conjuguées qui, lorsqu'elles seront au contact (ouvrage final) présenteront un intervalle extrêmement faible, de l'ordre du In this way, so-called conjugate surfaces are obtained which, when in contact (final work), will have an extremely small interval, of the order of
dixième de mm alors que lorsque les éléments sont fabri- tenth of a millimeter whereas when the elements are
qués indépendamment l'un de l'autre, cet intervalle est independently of each other, this interval is
de l'ordre du millimètre.of the order of a millimeter.
Il ne serait pas possible d'utiliser avec un intervalle aussi grand des matériaux polymérisables et expansifs en présence d'eau, ces matériaux ne convenant It would not be possible to use polymerizable and expansive materials in the presence of water with such a large
que pour boucher des fissures.only to plug cracks.
Dans le cas des voussoirs de pont et analogues, il est préconisé d'appliquer le matériau d'étanchéité sur les deux surfaces conjuguées avant de mettre les voussoirs en place mais à la différence du procédé classique, du fait que la polymérisation peut se faire à tout moment voulu puisque l'agent polymérisant est indépendant du matériau appliqué alors que dans le procédé classique le durcisseur est nécessairement mélangé avec la résine, on peut sans difficulté réaliser l'application du matériau d'étanchéité plusieurs jours avant de mettre les éléments de structure en place et, pour obtenir l'étanchéité, il suffit au moment voulu de mettre de l'eau ou un liquide aqueux en contact avec les surfaces conjuguées, par exemple par arrosage et par exemple In the case of bridge segments and the like, it is recommended to apply the sealant to the two mating surfaces before placing the segments in place, but unlike the conventional method, since the polymerization can be carried out at the same time. any desired time since the polymerizing agent is independent of the applied material while in the conventional method the hardener is necessarily mixed with the resin, it is possible without difficulty to apply the sealing material several days before putting the structural elements in place and, to obtain the seal, it is sufficient at the desired time to put water or an aqueous liquid in contact with the conjugate surfaces, for example by watering and for example
quelques heures avant la conjugaison des surfaces. a few hours before the conjugation of the surfaces.
Dans le cas du tunnel immergé et analogues, In the case of the submerged tunnel and the like,
il est préconisé de munir les surfaces conjuguées de cavi- it is recommended to provide the combined surfaces with cavities
tés en regard et de relier ces cavités à une face accessible de l'élément par un tube permettant, depuis l'extérieur, d'injecter le matériau d'étanchéité dans les facing each other and to connect these cavities to an accessible face of the element by a tube allowing, from the outside, to inject the sealing material into the
cavités alors que les surfaces sont conjuguées. cavities while the surfaces are conjugate.
L'eau nécessaire à la polymérisation-peut être mélangée au matériau avant injection ou après l'injection soit sous forme d'eau soit sous forme d'une solution aqueus On notera que, selon l'invention,'il n'est pas nécessaire que le matériau d'étanchéité soit appliqué sur l'intégralité des surfaces alors qu'aussi bien dans le cas de la feuille d'étanchéité que de la résine durcissable des techniques antérieures, le matériau d'étanchéité est The water required for the polymerization can be mixed with the material before injection or after the injection either in the form of water or in the form of an aqueous solution. It will be noted that according to the invention it is not necessary to the sealing material is applied to all of the surfaces, while both in the case of the sealing sheet and the curable resin of the prior art, the sealing material is
appliqué sur l'intégralité des surfaces. applied on all surfaces.
On décrira ci-après un exemple de réalisation An exemplary embodiment will be described below.
en se limitant au cas d'un tunnel immergé. limiting itself to the case of a submerged tunnel.
La figure 1 représente une coupe dans la paroi du tunnel à l'endroit de la jonction entre deux éléments voisins, l'étanchéité étant obtenue selon la technique FIG. 1 shows a section in the tunnel wall at the junction between two adjacent elements, the sealing being obtained according to the technique
classique, et -classic, and -
La figure 2 représente une coupe correspondante dans le cas o l'étanchéité est obtenue selon la présente invention. Sur la figure 1, les deux éléments de tunnel dont on a représenté seulement les extrémités A et B sont assemblés et l'assemblage est rendu étanche par une feuille de néoprène 1 qui était fixée à l'un des éléments avant l'assemblage Eventuellement du béton 2 est coulé après Figure 2 shows a corresponding section in the case where the seal is obtained according to the present invention. In Figure 1, the two tunnel elements which have been shown only the ends A and B are assembled and the assembly is sealed by a neoprene sheet 1 which was attached to one of the elements before assembly Possibly the concrete 2 is poured after
assemblage contrela feuille de néoprène. assembly against the neoprene sheet.
Dans la technique illustrée par la figure 2, les surfaces en regard 3 et 4 des deux éléments sont des surfaces conjuguées en sorte que l'intervalle entre les deux surfaces est au plus de l'ordre du 1 oème de mm alors que cet intervalle dans le cas classique (figure 1) peut atteindre plusieurs mm Les surfaces conjuguées 3 et 4 ont été munies, de préférence par moulage, de cavités en In the technique illustrated in FIG. 2, the facing surfaces 3 and 4 of the two elements are conjugate surfaces, so that the interval between the two surfaces is at most of the order of 1 ° of mm, whereas this interval in the conventional case (FIG. 1) can reach several millimeters. The conjugate surfaces 3 and 4 have been provided, preferably by molding, with cavities
