Abstract

Device for covering railway tracks in built-up areas, incorporating an effective system for filtering of noises. The invention relates to a device intended to obtain square metres which can be built upon directly for buildings for multiple uses. It consists of a succession of prefabricated gantry frames, covered on the underside by an acoustic protection and resting on low-frequency elastic supports capable of filtering the vibrations generated by passing trains. Lateral apertures permit the evacuation of transient excess pressures. The modular character of the invention means that it can be used without interfering with the rail traffic.

Description

DESCRIPTION
La presente invetion concerne un dispositif permettant d'obtenir a bon marche des metres carres constructibles en couvrant les chemins de fer, chaque fois qu'ils traversent à decouvert les quartiers residentiels des grandes agglomerations.DESCRIPTION
The present invention relates to a device making it possible to obtain inexpensive square meters by covering the railways, each time they cross the residential areas of large urban areas uncovered.

Cette technique existe déjà avec des solutions rigides (non suspendues) pour la réalisation de routes, de parkings ou d'espaces verts.This technique already exists with rigid solutions (not suspended) for the realization of roads, parking lots or green spaces.

La presente invention decrit un dispositif de couverture integrant un système d'isolation vibratoire filtrant les nuisances du passage des trains, completee d'une protection acoustique. Elle permet donc l'édification de batiments à vocation multiple (logement, commerce, loisir, bureau. The present invention describes a covering device incorporating a vibration isolation system filtering the nuisance of passing trains, complete with acoustic protection. It therefore allows the construction of multi-purpose buildings (housing, commerce, leisure, office.

Il existe à Paris et dans plusieurs capitales europeennes des dizaines de kilometres concernes (train et metro). In Paris and in several European capitals there are tens of kilometers concerned (train and metro).

Le dispositif de la présente invention est constitué de portiques, prefabriqués, en béton précontraint, directement installés sur les boites à ressorts et amortisseurs visqueux, ou plus généralement, sur des appuis élastiques a basse fréquence propre verticale. Le choix d'une fréquence d'installation, située entre 3 et 4 Hz, garantira un filtrage efficace des excitations du trafic ferroviaire.The device of the present invention consists of gantries, prefabricated, in prestressed concrete, directly installed on the boxes with viscous springs and dampers, or more generally, on elastic supports at low natural vertical frequency. The choice of an installation frequency, located between 3 and 4 Hz, will guarantee efficient filtering of rail traffic excitations.

L'exemple du dessin joint pour une double voie concerne des éléments 1 constitués de portiques préfabriqués en béton précontraint, longs de 16 mètres, larges de 2,5 mètres, reposants sur 4 appuis élastiques amortis. 0
La multiplication des éléments ttransportables par route et fer) permet la couverture rapide (sans perturber le reseau) des voies concernees. The example of the attached drawing for a double track concerns elements 1 made up of prefabricated prestressed concrete gantries, 16 meters long, 2.5 meters wide, resting on 4 damped elastic supports. 0
The multiplication of elements transportable by road and rail) allows rapid coverage (without disrupting the network) of the routes concerned.

La protection acoustique prefabriquée (2) qui assure l'insonorisation est intégree dans le portique.The prefabricated acoustic protection (2) which provides soundproofing is integrated into the gantry.

La presente invention prevoit, par ailleurs, des ouïes laterales 4 permettant l'évacuation des pressions dynamiques lors du passage du train.The present invention also provides lateral vents 4 allowing the evacuation of dynamic pressures during the passage of the train.

La presente invention reposera directement sur les fondations des voies ferrees. Pour une construction legere (un ou deux niveaux), il suffira d'installer le long du balast, sans autre preparation qu une mise a niveau, des banquettes prefabriquees. (i) destinées a recevoir les appuis élastiques. Les éléments iportiques et banquettes seront livres sur place par wagon grue qui pourra rapidement installer le matériel sans perturber le trafic ferroviaire (la nuit par exemple). Dés que le portique reposera sur ses appuis. le travail d'elevation pourra continuer sans mobiliser les voies coulee de la chape 6) The present invention will be based directly on the foundations of railroad tracks. For a light construction (one or two levels), it will be enough to install along the balast, without any preparation other than an upgrade, prefabricated benches. (i) intended to receive the elastic supports. The portal and bench elements will be delivered on site by crane wagon which can quickly install the equipment without disturbing rail traffic (at night for example). As soon as the gantry rests on its supports. the elevation work can continue without mobilizing the poured tracks of the screed 6)
