[0001] The construction of roadway tunnels using tunnel boring machines is a solution increasingly used, for both, economic and environmental reasons. With this technique, the machine excavates the soil and places precast segments, in order to form the wall of the tunnel, which becomes circular shaped. Subsequently, a filing on the bottom of the tunnel is executed in order to create a platform for the circulation of the vehicles, with the two-way traffic placed side by side.
[0002] In tunnels with more than one lane in each way, the diameter required is unacceptable for the existing tunnel boring machines. Furthermore, in the case of long tunnels, because of safety reasons, the solution is also problematic, being in general necessary to built two separated tunnels, one for each way of traffic. It will also be necessary to build evacuation galleries and/or shafts, regularly spaced along the tunnel, to allow for the evacuation of people in case of accident or fire inside the tunnel.
[0003] Document WO2004094785 which is considered the closest prior art document refers a circular tunnel with two independent roadway galleries, one for each way of traffic, but they are very much different, still being necessary to build a second tunnel. Document EP1191186A1 also refers a circular roadway tunnel with two levels provided with separating walls, but each level carries a single lane in each way, and the upper level only allows for the traffic of car passengers.
Technical domain of the invention
[0004] The present invention constitutes an innovative solution for the construction of roadway tunnels of circular section, with two-way traffic, allowing for the creation of two independent and identical roadway galleries, for all kinds of traffic, and a service gallery interconnected with them, in order to provide local access for the personnel and the evacuation of people in case of accident or fire inside the tunnel.
Description of the figures
[0005] This invention is illustrated in Figures 1, 2, 3, 4 and 5. Figure 1 shows a view of the tunnel. Figure 2 shows the current cross section of the tunnel. Figure 3 shows the cross section of the tunnel through a vertical access gallery. Figure 4 shows the longitudinal section of the tunnel. Figure 5 shows the plan of the tunnel at the upper roadway gallery.
Detailed description of the invention
[0006] The tunnel boring machine excavates the soil and places precast segments, which are clamped together, in order to form the wall of the tunnel (1), which is circular shaped.
[0007] Inside the tunnel, two slabs (2) (3) are executed, along its full width, one placed roughly at the mid high of the tunnel and the other placed slightly above the bottom of the tunnel, creating three overlapping galleries, isolated and independent: two identical roadway galleries (4) (5), one for each way of traffic, and a service gallery (6).
[0008] In the slabs (2) (3) openings (7) are arranged, placed closed to the circular wall of the tunnel (1), in one or in both sides, regularly spaced, and protected with fireguard devices of box type (8), provided with escape doors. The fireguard devices (8) on each side, are connected through closed vertical access galleries (10), which are provided with interior stairs, in order to allow for safe passage of people between the roadway galleries (4) (5) and the service gallery (6). The vertical access galleries (10) can be extended through the circular wall of the tunnel (1).
1. Roadway tunnel of circular wall (1) comprising two slabs (2) (3), characterized by one slab placed roughly at the half height of the tunnel and the other slab placed
slightly above the bottom of the tunnel, in order to create two independent and identical
roadway galleries, and a service gallery, which slab disposes of openings (7), regularly
spaced and placed along the circular wall (1), in one or both sides, protected with
fire devices of box type (8), provided with escape doors.
2. Tunnel according to claim 1, characterized by the fireguard devices cf box type (8), on each side, to be connected through closed
vertical access galleries (10), which are provided with interior stairs, to allow
for safe passage of people between the roadway galleries (4) (5) and the service gallery
(6).
3. Tunnel according to claims 1 and 2, characterized by the service gallery (6) to be provided with emergency vehicles of shuttle type (9),
which may suspended from the bottom slab (3), to allow for local access and the evacuation
of people.
1. Tunnel der ringmauer (1) durch, bestehend aus zwei platten (2) (3) aus, legte eine
platte ungefähr auf der halben höhe des tunnels und die andere platte platziert leicht
über dem boden des tunnels, um zwei unabhängige erstellen und identische fahrbahn
galerien, und ein service-galerie, die platten von öffnungen (7), regelmäßig angeordnet
und platziert entlang der ringmauer (1), in ein-oder beidseitig, geschützt mit feuer-geräte
der box-typ (8) zu verfügen, mit bereitgestellten fluchttüren.
2. Tunnel nach anspruch 1, gekennzeichnet durch die fireguard geräte der box-typ (8), auf jeder seite, um durch geschlossene vertikale zugang galerien (10), die mit innentreppe vorgesehen sind,
verbunden werden, um den sicheren verkehr von menschen zwischen ermöglichen fahrbahn
galerien (4) (5) und der service galerie (6).
3. Tunnel gemäß den ansprüchen 1 und 2, die von der service-galerie (6) mit einsatzfahrzeugen
der shuttle-typ (9), die aus der bodenplatte (3) suspendiert bereitgestellt werden
charakterisiert, um für den lokalen zugriff und die evakuierung von menschen ermöglichen.
1. Tunnel routier de paroi circulaire (1) caractérisée par comprenant deux dalles (2) (3), une dalle placée à peu près à demi-hauteur du tunnel
et la dalle d'autres placés légèrement au-dessus du fond du tunnel, afin de créer
deux galeries indépendants et identiques, et une galerie de service, quelles dalles
dispose de ouvertures (7), régulièrement espacés et placés le long du mur circulaire
(1), dans un ou les deux côtés, protégée par des dispositifs coupe-feu de type boîte
(8), fourni avec des portes échapper.
2. Tunnel selon la revendication 1, caractérisée par des dispositifs coupe-feu du type de boîte (8), de chaque côté, d'être reliés par
galeries accès vertical fermés (10), qui sont fournis avec escalier intérieur, pour
permettre le passage en sécurité des personnes entre les galeries routier (4) (5)
et la galerie de service (6).
3. Tunnel selon les revendications 1 et 2, caractérisé par la galerie de service (6) être fournis avec des véhicules d'urgence de type navette
(9), qui peuvent suspendu de la dalle de fond (3), pour permettre l'accès local et
l'évacuation des personnes.
