Description

COMPOSANTS EN BETON ARME POUR CONSTRUCTION RAPIDE DE PETITS OUVRAGES D'ART
PONCEAUX - GALERIES TECHNIQUES - PASSAGES SOUTERRAINS POUR PIETONS OU
VEHICULES LEGERS, etc...REINFORCED CONCRETE COMPONENTS FOR QUICK CONSTRUCTION OF SMALL WORKS OF ART
CULVERTS - TECHNICAL GALLERIES - UNDERGROUND PASSAGEWAYS
LIGHT VEHICLES, etc ...

Le présent système par composants mi-lourds en béton armé autorise la construction rapide de petits ouvrages d'art (Ponceaux - Galeries Techniques
Passages Souterrains pour piétons, véhicules légers, etc...) Il intéresse plus particulierement les maîtres d'ouvrages et maîtres d'oeuvre, se trouvant devant un problème d'intervention rapide et souhaitant limiter le blocage d'une route ou autre voie de circulation. Le système permet, par exemple, de travailler en alternance avec le blocage d'une demi-voie, la pose des éléments, la remise en service avant la coupure de la seconde demi-voie. Les ouvrages ainsi créés peuvent supporter directement le passage de véhicules lourds, ou recevoir des remblais importants.The present system of semi-heavy reinforced concrete components allows the rapid construction of small engineering structures (Culverts - Technical Galleries
Underground crossings for pedestrians, light vehicles, etc.) It is of particular interest to building owners and project managers, faced with a problem of rapid intervention and wishing to limit the blocking of a road or other lane circulation. The system allows, for example, to work alternately with the blocking of a half-track, the installation of the elements, the return to service before the cut-off of the second half-track. The structures thus created can directly support the passage of heavy vehicles, or receive significant embankments.

Dans le présent, la plupart de ces petits ouvrages d'art à section carrée ou rectangulaire sont coulés en place, provoquant ainsi le barrage d'une voie pour d'assez nombreuses journées ou semaines.In the present, most of these small structures of square or rectangular section are poured in place, thus causing the blocking of a track for quite many days or weeks.

Les composants du présent système dérivent de modules simples : murs en L placé verticalement - dalles de fil d'eau assemblées à la semelle des murs par aciers en attente - dalles de couverture posées sur joint et clavetées.The components of this system are derived from simple modules: L-shaped walls placed vertically - slabs of water wire assembled to the sole of the walls by pending steel - cover slabs placed on joints and keyed.

Il ne nécessite pas l'utilisation d'étais, et de ce fait procure un gain de temps créciable. It does not require the use of props, and therefore provides a credible time saving.

Ces composants produits en fabrication industrielle, après étude béton armé selon chaque cas, sont coffrés dans des moules métalliques assurant des côtes précises. Les moules sont prévus pour répondre à tout besoin d'épaisseur de voile, par des systèmes de rablettes mobiles. La mise en oeuvre des éléments en usine, dont les fabrications sont controlées par des services de qualification nationaux, permet de garantir un béton armé hautes performances, qui répondra facilement aux sollicitations en oeuvre.These components produced in industrial manufacturing, after a reinforced concrete study according to each case, are cased in metal molds ensuring precise dimensions. The molds are designed to meet any need for the thickness of the veil, using mobile rablette systems. The use of elements in the factory, the manufacturing of which is controlled by national qualification services, guarantees high-performance reinforced concrete, which will easily respond to the demands made.

Cette production en éléments de 2m40 autorise le transport au gabarit routier, et au tonnage complet des véhicules. Le système couvre la gamme comprise entre les productions manufacturées, en section cylindrique, carrée ou rectangulaire, et les ouvrages coulés in-situ. Soit de 3 m2 à 15 m2 de section, faisant suite par exemple aux éléments rectangulaires de lm25 x 2m50 ou circulaires de diamètre intérieur 2m00. Ceci tout en mettant à disposition des éléments, dont le poids unitaire ne dépasse pas celui des sections monoblocs citées ci-dessus. Un avantage est à retenir par rapport au cylindrique, à section utile égale la hauteur moindre permet un passage plus facile sous chaussée. This production in elements of 2m40 authorizes the transport to the road gauge, and to the complete tonnage of the vehicles. The system covers the range between manufactured productions, in cylindrical, square or rectangular cross-section, and works cast in situ. Either from 3 m2 to 15 m2 in section, following for example the rectangular elements of lm25 x 2m50 or circular elements of internal diameter 2m00. This while making available elements, the unit weight of which does not exceed that of the one-piece sections mentioned above. An advantage is to be remembered compared to the cylindrical, with a useful cross section equal to the lower height allowing easier passage under the road.

La dalle supérieure est calculée pour recevoir le passage de surcharges roulantes, sur simple bande de roulement depuis OmlO. Ou des charges de remblai de plusieurs mètres.The upper slab is calculated to receive the passage of rolling overloads, on a simple tread from OmlO. Or fill loads of several meters.

Le jointoiement entre éléments est double. D'une part, clavetage des éléments entre eux pour éviter les délignements sous l'effet de poussées ou surcharges différentielles. Ce clavetage réalisé en béton armé par les aciers en attente, ou par boulonnage avec douilles et éclisses.The jointing between elements is double. On the one hand, keying of the elements together to avoid edging under the effect of pushes or differential overloads. This keying carried out in reinforced concrete by the waiting steels, or by bolting with sockets and fishplates.

D'autre part, un joint double en élastomère ou autre matériau assure l'étanchéité de l'extérieur vers l'intérieur ou vice-versa.On the other hand, a double seal made of elastomer or other material seals from the outside to the inside or vice versa.

La répartition au sol est de meilleure qualité qu'avec des conduits circulaire. Si nécessaire, la dalle radier peut se trouver moulée en béton lourd, densité 3,5 à 5,5 ceci pour renforcer la stabilité, en assurant un lestage.The distribution on the ground is of better quality than with circular ducts. If necessary, the slab slab can be molded in heavy concrete, density 3.5 to 5.5 this to enhance stability, ensuring ballasting.

La stabilité de la dalle supérieure est renforcée par des tiges d'acier dont la section est retenue fonction des exigences de travail. Ces tiges placées verticalement dans les pied-droits et reliées à l'armature sont clavetées dans des gorges aménagées dans les éléments de dalles supérieures.The stability of the upper slab is reinforced by steel rods, the section of which is selected according to the work requirements. These rods placed vertically in the right legs and connected to the frame are keyed in grooves arranged in the elements of upper slabs.

Il est possible de préparer des changements de direction en fabriquant les éléments de pied-droits à pans coupés, et des éléments de semelles et de dalles de couverture moulées selon besoin, à l'aide de rablettes mobiles dans les moules.It is possible to prepare changes of direction by manufacturing the right-footed elements with cut sides, and elements of soles and cover slabs molded as required, using movable rablettes in the molds.

La dalle radier peut se trouver moulée avec une cunette ou un dièdre permettant un auto-curage permanent en basses eaux, s'il s'agit d'un émissaire, ou l'évacuation d'eaux collectées en amont, s'il s'-agit d'une galerie piétons ou technique.The slab slab can be molded with a wedge or a dihedral allowing permanent self-cleaning in low water, if it is an outfall, or the evacuation of water collected upstream, if -is a pedestrian or technical gallery.

Dans le cas de surcharges exceptionnelles ou de remblais très importants, la dalle supérieure peut se trouver moulée en reforçant l'épaisseur au centre, pour une coupe en dièdre inversé, ceci selon résultat du calcul et des exigences de renforcement de section.In the case of exceptional overloads or very large embankments, the upper slab can be molded by strengthening the thickness in the center, for an inverted dihedral cut, this depending on the calculation and section reinforcement requirements.

Les éléments sont ainsi conçus
Elément L en béton armé avec gousset (1), comportant en semelle des aciers en attente soit pour clavetage avec la dalle de semelle, soit pour clavetage avec l'autre élément L (2). Sur la tranche verticale une feuillure pour jointoiement (3). Cette feuillure se poursuit sur la tranche supérieure (4).The elements are thus designed
Reinforced concrete element L with gusset (1), comprising steel on standby either for keying with the sole plate, or for keying with the other element L (2). On the vertical edge a rebate for jointing (3). This rebate continues on the upper edge (4).

Les épaisseurs de béton, les quantités d'armatures, les hauteurs de piedroits, les largeurs de semelles, sont calculés suivant le type d'ouvrage et au coup par coup.The thicknesses of concrete, the quantities of reinforcement, the heights of corners, the widths of footings, are calculated according to the type of work and piecemeal.

La dalle semelle ou fil d'eau vient se placer en (5). S'il s'agit d'une dalle de lestage, elle est réalisée en béton lourd. Elle peut se présenter avec une cunette (6) ou un dièdre (7). Dans tous les cas, elle peut recevoir un revêtement anti-abrasion,ou un revêtement noble, s'il s'agit d'un partie circulée (8). Le revetement peut se trouver prévu également sur les parois verticales (9). Des aciers en attente depuis l'armature de la dalle fil d'eau permettent d"assurer son clavetage avec les pied-droits (10). The sole or water slab is placed in (5). If it is a ballast slab, it is made of heavy concrete. It can be presented with a wedge (6) or a dihedral (7). In all cases, it can receive an anti-abrasion coating, or a noble coating, if it is a circulating part (8). The coating can also be provided on the vertical walls (9). Steels pending from the reinforcement of the water slab allow it to be keyed in with the straight feet (10).

Une forme (11) étudiée et réalisee en fonction des exigences sera réglée pour permettre une pose sans point dur.A shape (11) studied and produced according to the requirements will be adjusted to allow installation without a hard point.

La dalle supérieure (12) étudiée en fonction des surcharges roulantes ou des charges de remblais sera d'épaisseur variable selon l'étude. Elle pourra se trouver réalisée avec un dièdre inversé (13) en deux pans égaux, pour renforcement. Sur sa face inférieure, qui peut se trouver traitée en parement noble, deux décrochements (14) permettent la pose en encastrement.The upper slab (12) studied as a function of rolling overloads or fill loads will be of variable thickness depending on the study. It may be carried out with an inverted dihedral (13) in two equal sections, for reinforcement. On its underside, which can be treated with noble facing, two recesses (14) allow installation in recess.

Une feuillure (15) de même forme que celle des pied-droits et dalle de semelle assure la continuité pour le jointoiement. Un évidement (16) apparaît sur la face supérieure et sur les deux bords extérieurs de cette dalle. Il permettra un clavetage armé (17) avec étanchéité. Des douilles de manutention (18) sont prévues en divers points pour permettre la prise des pièces à l'aide d'élingues et opérer les manutentions de chargement, déchargement et pose avec équilibrage de l'élément. Des tiges filetées (19) sont clavetées dans des gorges (20). Les joints élastomères sont collés en lignes parallèles sur chaque tranche (21).A rebate (15) of the same shape as that of the right feet and sole plate provides continuity for the jointing. A recess (16) appears on the upper face and on the two outer edges of this slab. It will allow a reinforced keying (17) with sealing. Handling sleeves (18) are provided at various points to allow the gripping of the parts using slings and operate the handling of loading, unloading and laying with balancing of the element. Threaded rods (19) are keyed into grooves (20). The elastomer seals are glued in parallel lines on each edge (21).
