Abstract
Description
La présente invention est du domaine des conduits de grande dimension, notamment en coupe transversale. The present invention is in the field of large conduits, in particular in cross section.
Elle vise plus particulièrement des conduits préfabriqués en éléments longitudinaux a deux articulation-s et voûte souple ainsi qu'un procédé pour leur fabrication.It relates more particularly to prefabricated conduits in longitudinal elements with two articulations and flexible arch as well as a process for their manufacture.
Jusqu'à présent il n'avait pas été possible de réaliser des conduits de grande dimension, en coupe transversale, qui ne donnaient pas entière satisfaction, du fait d'une portance médiocre et d'un manque de flexibilité au niveau de l'élément de voûte. Up to now, it has not been possible to produce large cross-sectional conduits, which were not entirely satisfactory, due to a poor bearing capacity and a lack of flexibility at the level of the element. arch.
Un objet de la présente invention est de réaliser un conduit de grande dimension, notamment utilisable pour le transport des fluides sans pression ou sous faible pression, qui obvie aux inconvénients des constructions similaires de la technique antérieure, tout en permettant la réalisation, de façon aisée, d'un produit présentant d'excellentes caractéristiques au niveau de l'utilisation, notamment comme conduite enterrée. An object of the present invention is to provide a large pipe, in particular usable for the transport of fluids without pressure or under low pressure, which obviates the drawbacks of similar constructions of the prior art, while allowing the realization, in an easy way , of a product with excellent characteristics in terms of use, in particular as a buried pipe.
La présente invention a donc pour objet un conduit de grande dimension, en coupe transversale, comportant, par section, au moins deux éléments principaux, à savoir un élément de voûte et un élément de fond, caractérisé en ce que chaque section est constituée d'au moins un élément de voûte d'un seul tenant, reposant sur un élément de fond ou radier à fond plat, par l'intermédiaire de joints à rotule, façonnés sur les bords inférieurs latéraux de l'élément de voûte, et venant s'encastrer dans des gouttières correspondantes, ménagées en les zones latérales du radier et comportant au moins un élément d'étanchéité. The present invention therefore relates to a large duct, in cross section, comprising, by section, at least two main elements, namely a roof element and a bottom element, characterized in that each section consists of at least one arch element in one piece, resting on a bottom element or to radiate a flat bottom, by means of ball joints, formed on the lateral lower edges of the arch element, and coming from embed in corresponding gutters, formed in the lateral areas of the raft and comprising at least one sealing element.
Le conduit de la présente invention est en outre remarquable par les points suivants
- l'élément de voûte est semi-circulaire; l'élément de voûte comporte un ferraillage plié en épingle à cheveux au niveau des zones des rotules, de façon à présenter une double nappe dans la demi-zone inférieure de la voûte et une simple nappe dans la demi-zone supérieure de la voûte; la double nappe s étendant jusqu'au niveau du point d'inversion d'effort afin d'obtenir une souplesse relative de la demi-zone supérieure de la voûte; des moyens de maintien, avantageusement constitués par un dispositif de boulonnage prenant appui sur l'épaulement d'un bossage latéral, solidaire de l'élément de voûte, et venant se visser dans un écrou noyé dans la masse au niveau des zones latérales du radier; le bossage peut être linéaire ou continu; les moyens de maintien peuvent être constitués par un système de précontrainte de type câble incorporé ou coulissant; l'élément d'étanchéité au niveau des joints rotules est constitué par du néoprène, de la feuille de plomb ou tout produit susceptible de fournir une bonne étanchéité entre la voûte et le radier; l'élément de voûte pourra être d'épaisseur différentielle.The conduit of the present invention is further remarkable by the following points
- the arch element is semi-circular; the arch element comprises a reinforcement folded in a hairpin at the areas of the ball joints, so as to present a double ply in the lower half-zone of the vault and a single ply in the upper half-zone of the vault; the double ply extending to the level of the force reversal point in order to obtain a relative flexibility of the upper half-zone of the arch; holding means, advantageously constituted by a bolting device bearing on the shoulder of a lateral boss, integral with the arch element, and coming to be screwed in a nut embedded in the mass at the lateral zones of the raft ; the boss can be linear or continuous; the holding means can be constituted by a prestressing system of the incorporated or sliding cable type; the sealing element at the ball joints is made of neoprene, lead sheet or any product capable of providing a good seal between the arch and the base; the arch element may be of differential thickness.
D'autres avantages et caractéristiques de l'invention apparaltront à la description, non limitative, suivante d'une forme de réalisation particulière de conduits de grande dimension, selon l'invention, en référence aux dessins annexés, dans lesquels
Fig. 1 est une vue debout d'un conduit de grande dimension, selon l'invention; et
Fig. 2est une vue en coupe transversale du conduit de la figure 1.Other advantages and characteristics of the invention will appear on the following non-limiting description of a particular embodiment of large conduits, according to the invention, with reference to the accompanying drawings, in which
Fig. 1 is a standing view of a large pipe, according to the invention; and
Fig. 2 is a cross-sectional view of the conduit of FIG. 1.
Comme représenté sur les dessins, chaque section d'un conduit de l'invention est constituée d'un élément de voûte semi-circulaire 1 dont les bords intérieurs façonnés en rotule la, reposent dans des gouttières longitudinales 3 ménagées dans les faces supérieures des zones latérales d'un radier 2, présentant un fond plat 2a se prolongeant par des secteurs latéraux cylindriques 2b. As shown in the drawings, each section of a conduit of the invention consists of a semicircular arch element 1, the inner edges of which are formed in a ball joint 1a, lie in longitudinal gutters 3 formed in the upper faces of the zones lateral of a slab 2, having a flat bottom 2a extending by cylindrical lateral sectors 2b.
Au niveau du joint rotule (la,3) est prévue une solution d'étanchéité, avantageusement constituée par du néoprène ou bien de la feuille de plomb. At the ball joint (la, 3) is provided a sealing solution, advantageously constituted by neoprene or else lead sheet.
Bilatéralement à la voûte 1, sont prévus des bossages 4, linéaires ou continus, comportant des trous traversant verticaux par lesquels passent des boulons 5 venant se visser dans des écrous noyés 6 disposés dans les zones latérales du radier 2. Bilaterally to the roof 1, bosses 4 are provided, linear or continuous, comprising vertical through holes through which pass bolts 5 which are screwed into embedded nuts 6 arranged in the lateral zones of the raft 2.
Comme il apparaît clairement sur la figure 2, la nappe de ferraillage 7 est disposée à l'intérieur de la voûte 1 de façon à se replier en épingle à cheveux, au niveau des rotules la et constituer ainsi jusqu'au niveau du point d'inversion d'effort, c'est-à-dire dans la présente forme de réalisation jusqu'à mi-hauteu de la voûte une double épaisseur de nappe de ferraillage. Cet agencement particulier de la nappe de ferraillage 7 au niveau des rotules la permet un meilleur encaissement des charges par lesdites rotules la, tandis que la solution de nappe de ferraillage unique au niveau du sommet de la voûte permet une meilleure flexibilité de cette dernière. As it clearly appears in FIG. 2, the reinforcement ply 7 is arranged inside the vault 1 so as to fold back in a hairpin, at the level of the ball joints and thus constitute up to the level of the point of force reversal, that is to say in the present embodiment up to mid-height of the arch, a double thickness of reinforcement ply. This particular arrangement of the reinforcement ply 7 at the level of the ball joints la allows better collection of the loads by said ball joints la, while the solution of single reinforcement ply at the level of the top of the vault allows better flexibility of the latter.
Ainsi se trouve résolu selon la présente invention, le problème des conduits de grande dimension en coupe transversale, grâce à la coopération entre une voûte et un radier, par l'intermédiaire d'une liaison à rotule, au niveau de laquelle est prévu à l'intérieur de la voûte, un ferraillage en épingle à cheveux, permettant une meilleure portance de la voûte 1 sur le radier 2
L'invention fournit également un procédé d'obtention des conduits de grande dimension, par assemblage d'au moins un élément de voûte préfabriqu#é, avec un élément de fond confectionné sur place en béton et constituant le radier du conduit, un élément d'étanchéité étant disposé entre les bords de voûte conformés en rotule et les gouttières latérales du radier au fur et à mesure de la confection dudit radier.Thus is solved according to the present invention, the problem of large conduits in cross section, thanks to the cooperation between a vault and a raft, via a ball joint, at which is provided at l inside the vault, a hairpin reinforcement, allowing a better lift of the vault 1 on the raft 2
The invention also provides a process for obtaining large conduits, by assembling at least one prefabricated vault element, with a bottom element made on the spot in concrete and constituting the base of the conduit, an element of sealing being arranged between the edges of the vault formed in a ball joint and the lateral gutters of the raft as and when the said raft is made.
La présente invention trouve avantageusement son application pour de nombreux usages, par exemple pour la construction de conduites d'eau sous faible pression et sans pression, les abris anti-atomiques ou autres, les passages sur remblai importants, les silos a usage militaire ou civil, et constructions analogues
Bien que les éléments constitutifs du c-onduit de l'invention soient dans la présente réalisation fabriqués en béton armé, il est évident que n'importe quel béton ou matériau approprié peut être mis en oeuvre, par exemple de la fonte ductile, de l'acier, de l'aluminium, des alliages d'aluminium et analogues. The present invention advantageously finds its application for numerous uses, for example for the construction of water pipes under low pressure and without pressure, atomic or other shelters, passages on important embankments, silos for military or civil use. , and similar constructions
Although the constituent elements of the joint of the invention are in the present embodiment made of reinforced concrete, it is obvious that any concrete or suitable material can be used, for example ductile iron, l steel, aluminum, aluminum alloys and the like.
