Abstract
Description
L'invention concerne la protection, par un revêtement, du béton d'une canalisation en béton destinée à l'écoulement d'un liquide corrosif, contre un contact avec ce liquide, la canalisation étant constituée par sections successives formées chacune d'une couronne de voussoirs en béton mis en place et assemblés de proche en proche in-situ. The invention relates to the protection, by a coating, of the concrete of a concrete pipe intended for the flow of a corrosive liquid, against a contact with this liquid, the pipe being constituted by successive sections each formed of a crown concrete segments set up and assembled in situ.
L'invention s'applique notamment à une canalisation réalisée dans un sol terrestre ou marin creusé au moyen d'un tunnelier, par exemple une canalisation de 1 à 15 m de diamètre. The invention applies in particular to a pipe made in a terrestrial or marine ground dug by means of a tunnel boring machine, for example a pipe of 1 to 15 m in diameter.
On appelle voussoir un élément préfabriqué qui a sensiblement la forme d'une portion de cylindre en sorte que plusieurs voussoirs assemblés de proche en proche constitue une couronne cylindrique ou à peu près cylindrique. It is called voussoir a prefabricated element which has substantially the shape of a cylinder portion so that several voussoirs assembled step by step is a cylindrical crown or roughly cylindrical.
Habituellement, après la mise en place des voussoirs, un revêtement de mortier est réalisé sur la face interne de la canalisation et, s'il y a lieu de protéger le béton de l'action du liquide, un revêtement d'un matériau adéquat peut être réalisé sur la couche de mortier. Usually, after the establishment of the voussoirs, a mortar coating is made on the inner face of the pipe and, if it is necessary to protect the concrete from the action of the liquid, a coating of a suitable material can be made on the mortar layer.
La présente invention vise à assurer la protection du béton de façon moins onéreuse et plus rapide. The present invention aims to ensure the protection of concrete in a less expensive and faster way.
On y parvient selon l'invention en protégeant chaque voussoir individuellement par un revêtement de protection intégré au voussoir, avant la pose du voussoir, sur les faces du voussoir susceptibles de se trouver au contact du liquide corrosif. This is achieved according to the invention by protecting each voussoir individually by a protective coating built into the voussoir, before the installation of the voussoir, on the sides of the voussoir likely to be in contact with the corrosive liquid.
Il s'agit donc de l'intégralité de la face du voussoir qui sera tournée vers l'intérieur de la canalisation et de tout ou partie des faces de joint, c'est- à-dire des tranches, du voussoir qui seront en vis à vis des tranches correspondantes des voussoirs adjacents. It is therefore the entirety of the face of the voussoir which will be turned towards the inside of the pipe and all or part of the joint faces, that is to say, the slices, the voussoir which will be screwed to the corresponding slices of the adjacent voussoirs.
Dans une réalisation préférée, on préfabrique le voussoir par coulage et durcissement du béton dans un moule dont les parois sont revêtues d'un film dudit revêtement aux endroits adéquats, avant le coulage. On décrira ci-après un exemple de mise en ceuvre de l'invention, en référence aux figures du dessin joint sur lequel - la figure 1 est un schéma en coupe verticale d'une section de canalisation réalisée par une technique conventionnelle, - la figure 2 est une perspective schématique d'un voussoir, On a représenté schématiquement sur la figure 1 une section droite verticale d'un terrain (1) dans lequel on a foré au moyen d'un tunnelier un tunnel (2). Dans ce tunnel, au moyen de bras prévus sur le tunnelier, on a mis en place, section par section, des couronnes de voussoirs (3) préfabriqués en béton, l'ensemble des couronnes des différentes sections constituant une canalisation. Sur la face interne de cette conduite, on a réalisé une couche (4) en mortier et, sur cette couche, on a appliqué un revêtement de protection (5). In a preferred embodiment, the voussoir is prefabricated by pouring and curing the concrete in a mold whose walls are coated with a film of said coating in the appropriate places, before pouring. An example of implementation of the invention will be described below, with reference to the figures of the accompanying drawing in which: - Figure 1 is a diagram in vertical section of a section of pipe made by a conventional technique, - the figure 2 is a schematic perspective of a voussoir, schematically shown in Figure 1 a vertical cross section of a field (1) in which was drilled by means of a tunnel tunnel (2). In this tunnel, by means of arms provided on the tunneling machine, section by section were set up crowns of segments (3) prefabricated concrete, the set of crowns of the various sections constituting a pipe. On the inner face of this pipe, a mortar layer (4) was made and on this layer a protective coating (5) was applied.
S'il y a lieu, un matériau durcissable (6) a été injecté entre les voussoirs et le terrain. If necessary, a hardenable material (6) was injected between the voussoirs and the ground.
Cette technique est connue en soi et n'a pas besoin d'être décrite plus en détails. This technique is known per se and does not need to be described in more detail.
Selon la présente invention, on évite la réalisation de la couche (4) et la réalisation in-situ du revêtement (5) en préfabriquant chaque voussoir avec un revêtement de protection individuel. According to the present invention, it is avoided the realization of the layer (4) and the in-situ realization of the coating (5) by prefabricating each voussoir with an individual protective coating.
On a représenté sur la figure 2, un voussoir V, courbe, qui présente une face Va qui sera tournée vers l'intérieur de la conduite, une face Vb opposée qui sera tournée vers la formation de terre, deux tranches d'extrémité V, Vd qui seront en vis à vis des tranches d'extrémité correspondantes des voussoirs adjacents de la même section de canalisation, et deux tranches latérales Ve, V, qui seront en vis à vis des tranches latérales correspondantes des voussoirs adjacents des sections contiguës de la canalisation. FIG. 2 shows a voussoir V, curve, which has a face Va which will be turned towards the inside of the pipe, an opposite face Vb which will be turned towards the earth formation, two end slices V, Vd which will be opposite the corresponding end slices of the adjacent voussoirs of the same section of pipe, and two lateral slices Ve, V, which will be opposite the corresponding lateral edges of the adjacent voussoirs of the contiguous sections of the pipe .
Selon l'invention, la face Va et, en tant que de besoin, les tranches d'extrémité V,,, Vd et les tranches latérales VQ et Vf du voussoir sont protégées par un revêtement mis en place lors de la préfabrication du voussoir, par exemple un revêtement en film disposé dans le moule de préfabrication, aux endroits adéquats correspondants à cette face et aux tranches. According to the invention, the face Va and, as necessary, the end slices V ,,, Vd and the side slices VQ and Vf of the voussoir are protected by a coating set up during the prefabrication of the voussoir, for example a film coating disposed in the prefabrication mold, at the appropriate locations corresponding to this face and the slices.
Si les tranches du voussoir comportent des gorges G (visibles sur la figure 2 mais non représentées sur la figure 1) destinées à recevoir un matériau d'étanchéité pour assurer l'étanchéité du joint formé par les tranches en vis à vis de deux voussoirs contigus d'une même section ou de deux sections de canalisation adjacentes, le film de protection doit remonter sur la tranche au moins jusqu'à la gorge et le matériau d'étanchéité doit être choisi pour être résistant au liquide corrosif. If the segments of the voussoir comprise grooves G (visible in Figure 2 but not shown in Figure 1) for receiving a sealing material to seal the seal formed by the slices opposite two adjacent segments of the same section or two adjacent pipe sections, the protective film must go up on the wafer at least up to the groove and the sealing material must be chosen to be resistant to the corrosive liquid.
Le film de revêtement peut avantageusement être préformé avant d'être disposé dans le moule de fabrication du voussoir, par adhésif, etc La fixation du revêtement au voussoir est assurée par tout moyen approprié connu en soi, par exemple par des filaments que présente le revêtement sur ses faces tournées vers le voussoir et qui seront prisonniers de la matière durcie du voussoir. The coating film may advantageously be preformed before being placed in the mold for manufacturing the voussoir, by adhesive, etc. The fixing of the covering to the voussoir is ensured by any appropriate means known per se, for example by filaments that the coating presents. on its faces turned towards the voussoir and which will be prisoners of the hardened matter of the voussoir.
Le matériau du film est choisi en fonction de la nature du liquide pour résister à l'action chimique du liquide. Dans de nombreux cas un revêtement de polyéthylène, de polychlorure de vinyle ou d'une autre résine de synthèse convient.The film material is chosen according to the nature of the liquid to resist the chemical action of the liquid. In many cases a coating of polyethylene, polyvinyl chloride or other synthetic resin is suitable.
