Abstract

The principle of this method lies in the use of bridge floors (decks) which are prefabricated at their definitive location instead of the conventional auxiliary metal bridge decks used to shore up the various infrastructure constructions of rail bridges. The definitive decks rest on a device of vertical supports of a first phase on which the definitive reinforced concrete header beams bear, the preliminary production of these constructions requiring only a simple and local reinforcement of the track. The design of the infrastructure constructions for the rail bridge incorporates the first phase vertical supports. This method according to the invention is particularly designed for any civil engineering bridge construction work under a track, of the rail bridge type.

Description

Méthode de réalisation d'ouvrages d'art sous voie de chemin de fer en service, sans utilisation de tabliers métalliques auxiliaires.Method of making engineering structures under a railway track in service, without the use of auxiliary metal aprons.

La réalisation des ponts rails sur lignes en service par le processus habituel, qu'il s'agissed'un nouvel ouvrage ou d'élargissement d'ouvrage existant, implique actuellement en phase provisoire ltemploi de tabliers métalliques auxiliaires.The realization of rail bridges on lines in service by the usual process, whether it is a new structure or an extension of an existing structure, currently involves the temporary use of auxiliary metal decks.

Ces tabliers assurent le maintien de la circulation ferroviaire lors de la réalisation des appuis définitifs du pont : fondations par radier ou semelles, culées et sommiers. Les tabliers métalliques auxiliaires reposent sur des chevêtres en béton ou des camarteaux.These decks ensure the maintenance of rail traffic during the completion of the final supports of the bridge: foundations by slab or footings, abutments and box springs. The auxiliary metal aprons rest on concrete headers or camarteaux.

Ils sont déposés lors de l'intervalle, au cours duquel sont mis en place par levage ou ripage les tabliers définitifs préfabriqués en béton armé où poutrelles enrobées.They are placed during the interval, during which the final prefabricated reinforced concrete decks where coated beams are put in place by lifting or shifting.

apron.

Elle comporte ensuite la création de chevêtres en béton
armé reliant, pour chaque file d'appuis, les supports
verticaux précédents, ce travail se situant également
en sous oeuvre des voies exploitées.It then involves the creation of concrete headers
armed connecting, for each support queue, the supports
previous verticals, this work also being
in under construction of the exploited channels.

Au cours de cette première phase chaque file de rails
est renforcée grâce à la pose préalable de supports de
rails S4.During this first phase each line of rails
is reinforced by the prior installation of supports
S4 rails.

veau tablier, les terrassements nécessaires à la création des
ouvrages d'infrastructure sont exécutés par phases compati
bles avec les performances propres des supports verticaux
en cours d'exécution de cette dernière phase.c / During an interval with power outages
under the catenary, operations are carried out
stops below
- Removal of the track section in the area concerned

Les dispositions de ces croquis sont décrites comme suit, étant encore rappelé que les supports verticaux réalisés en première phase peuvent être de nature quelconque choisies cas par cas en fonction des données de l'espèce, en particulier des caractéristiques des terrains dans la zone concernée. The provisions of these sketches are described as follows, it being further recalled that the vertical supports produced in the first phase may be of any nature chosen case by case according to the data of the species, in particular the characteristics of the land in the area concerned.

Phase 1 : Exécution des supports initiaux (figures dans cet exemple par des puits circulaires) (1), la méthode employée étant fonction de la nature du sol.Phase 1: Execution of the initial supports (figures in this example by circular wells) (1), the method used being dependent on the nature of the soil.

I1 est disposé, noyes dans le béton des puits, des profilés métalliques (2) ultérieurement utilisés comme supports verticaux de blindages au moment de l'exécution des terrassements. I1 is arranged, embedded in the concrete of the wells, metal profiles (2) subsequently used as vertical supports for shielding at the time of the execution of the earthworks.

Côté intérieur de l'ouvrage un coffrage grossier (3) est disposé dans chaque puits suivant une corde de cercle extérieur du puits, dégageant une surface plane munie d'armatures en attente, facilitant l'intégration des puits à la future culée.On the interior side of the structure, a coarse formwork (3) is placed in each well along an outside circle cord of the well, freeing up a flat surface provided with pending reinforcement, facilitating the integration of the wells into the future abutment.

Le diamètre des puits est notamment fonction de la pression au sol admissible en phase provisoire, c'est-à-dire avant exécution des supports définitif s.The diameter of the wells is notably a function of the permissible ground pressure in the provisional phase, that is to say before execution of the final supports s.

Phase 2 : Pose de supports de rails type S4 (4) assurant la rigidité de la voie afin de permettre sous vitesse ralentie l'exécution du terrassement nécessaire à la confection des deux chevêtres sommiers (5).Phase 2: Installation of S4 type rail supports (4) ensuring the rigidity of the track in order to allow under slow speed the execution of the earthwork necessary for the making of the two box springs (5).

Avant coulage du béton des chevêtres des profilés métalliques sont battus à partir du fonds de fouille pour complèter le dispositif vertical de blindage ultérieur constitué par les profilés déjà noyés dans le béton des puits.Before pouring the concrete of the headers, the metal profiles are beaten from the excavation bottom to complete the vertical device for subsequent shielding constituted by the profiles already embedded in the concrete of the wells.

Phase 3 : Elle comporte le coffrage, le ferraillage et le coulage du béton des chevêtres (6) lesquels sont dotés de chanfreins assurant l'écoulement des eaux de ruissellement et de niches à vérins (8) utilisées lors de la descente du (ou des) nouveau tablier sur ses appuis définitifs (figures 2 et 3).Phase 3: It includes the formwork, the reinforcement and the pouring of the concrete of the headers (6) which are provided with chamfers ensuring the flow of runoff water and niches with jacks (8) used during the descent of the (or ) new deck on its final supports (Figures 2 and 3).

Phase 4 : Des camarteaux sont ensuite placés sur les chevêtres pour supporter la voie après dépose des supports S4.Phase 4: Camarteaux are then placed on the headers to support the track after removing the S4 supports.

Phase 5 : Réalisation des palées latérales (9) sur lesquelles sont préfabriqués les tabliers.Phase 5: Realization of the side platforms (9) on which the decks are prefabricated.

Phase 6 : Préfabrication des nouveaux tabliers (10) (figure
3).Phase 6: Prefabrication of the new decks (10) (figure
3).

Les phases 5 et 6 peuvent être engagées dès l'ouverture du chantier en fonction du planning des travaux.Phases 5 and 6 can be started at the opening of the site depending on the work schedule.

Phase 7 : Après mise hors service, dépose d'une voie pour pose du premier tablier (figure 4). Phase 7: After decommissioning, removal of a track for the installation of the first deck (Figure 4).

Inexécution du terrassement jusqu'au niveau inférieur des chevêtres et, s'il y a lieu, dépose du demi-tablier existant. Failure to perform earthworks to the lower level of the headers and, if necessary, remove the existing half-deck.

Phase 8 : Amenée du tablier par ripage à son emplacement définitif et descente par vérins sur ses appuis et rétablisserment de la voie. (Figure 5).Phase 8: Bringing the deck by shifting to its final location and lowering by jacks on its supports and restoring the track. (Figure 5).

Phase 9 : Même opération pour le second tablier..Phase 9: Same operation for the second deck.

Phase 10 : En sous oeuvre des tabliers (10) exécution des terrassements par phases compatibles avec la stabilité en situation provisoire des supports réalisés en phase 1.Phase 10: Under construction of the decks (10) execution of earthworks in phases compatible with the stability in a temporary situation of the supports produced in phase 1.

(Figure 6).(Figure 6).

Eventuellement démolition des culées de l'ouvrage existant.Possibly demolition of the abutments of the existing structure.

Pose à l'avancement (et si nécessaire) d'un blindage (11) entre les puits en utilisant les profilés prévus à cet effet.Laying the advancement (and if necessary) of a shield (11) between the wells using the profiles provided for this purpose.

Exécution du demi radier et de la culée correspondante puis de l'autre demi radier et de l'autre culée.Execution of the half raft and the corresponding abutment then of the other half raft and the other abutment.

Dans le cas d'un pont rail sur semelles ou d'un pont rail sur voie unique, variantes non illustrées, le mode opératoire est le même dans son principe.In the case of a rail bridge on flanges or a rail bridge on a single track, variants not shown, the procedure is the same in principle.

Le ou les tabliers en poutrelles enrobées ou en béton armé définitifs peuvent aussi ne pas être préfabriqués sur place.The deck (s) made of permanent coated beams or reinforced concrete may also not be prefabricated on site.

Cette variante non illustrée ne modifie pas sensiblement le mode opératoire et s'inscrit strictement dans lecadre du même procédé. This variant not illustrated does not significantly modify the operating mode and is strictly within the framework of the same process.
