Definitions
- the object of the present invention is a wall security interior for underground works, especially for tunnels, aimed at limiting risks of human loss and related material damage to such often tragic events.
- the invention is defined by claim 1 of the patent.
- the attached drawing represents, schematically and at for example, a one-lane road tunnel, of which the interior walls conform to this invention.
- Figure 1 is a cross-sectional view of the tunnel, the fire nozzles being open.
- Figure 2 is an elevational view of part of its inner wall.
- Figure 3 is a sectional view (section) by the line III-III of figure 2.
- the tunnel shown is pierced in natural rock.
- a shell A of insulating and insulating material covers the inner surface of the rock. This hull drains runoff so that it doesn't degrade the concrete B sprayed or cased laterally so as to support circulation slab C or ceiling D.
- the side walls of the tunnel are made up of slightly curved panels 10, juxtaposed and mechanically fixed removably against structural support.
- the empty spaces F can be used for the passage ducts or technical pipes.
- Each panel 10 is formed (FIGS. 2 and 3) by two plates 11 and 12, in mechanically very resistant and stainless metal, for example in aluminum, welded edge to edge, constituting the two slices of a Sanswich structure whose soul is a space 13 filled with a certain volume of cold water under pressure.
- These plates 11 and 12 have recessed parts and in relief giving them very good resistance mechanical to the deformation so that their spacing practically does not vary under the action of pressure some water. To strengthen this resistance, they could be mechanically connected by welding bridges or tie rods.
- the spaces 13 are supplied with pressurized cold water by pipes 14 arranged in semi-cylindrical housings provided in structural shell spans supporting slab C and ceiling D.
- These pipes 14, which are protected by grids, are part of a closed hydraulic network (Ringtechnisch, hydrants, pumps, penstocks, elevation tanks, etc. ).
- a number of fire nozzles 15 are distributed on the external surfaces of the plates 12. They are supplied with pressurized water contained in spaces 13.
- the nozzles 15 in this zone open automatically and project continuously to the center of the tunnel, a beam of powerful jets of cold water which cools the ambient air, and allows the if not, otherwise eliminate a fire source, except at the very least to limit its extension.
- the wall is also operational when panels 10 are damaged by impact caused by a vehicle, because water escaping from resulting openings, cools the atmosphere which reduces the risk of fire.
- Pressurized cold water could also be mixed with ingredients with properties particular such as an anti-freeze, a product foaming etc.
- wall according to the invention could be used in other underground works than in road tunnels, for example in tunnels railways, metro tracks, underground passages, military installations, caves, galleries shelters of all kinds, parking lots, etc. etc.
- the concrete shell could extend to panels 10, so these panels would then constitute a coating applied directly on the drainage layer, or, alternatively, directly on the rock.

Abstract
Lorsque la température atteint une valeur anormalement élevée dans une zone du tunnel, les buses (15) concernées s'ouvrent automatiquement et projettent des jets continus sur les véhicules, engins, appareils qui s'y trouvent.
Description
Claims (8)
- Paroi intérieure de sécurité pour ouvrages sous-terrains, par exemple de tunnels, caractérisé par le fait qu'elle est constituée par des panneaux (10) limitant chacun un espace (13) rempli liquide froid sous pression, par des buses anti-incendie (15) reliées auxdits espaces (13), ceux-ci comportant des moyens permettant de les relier à une source de liquide froid sous pression, le tout de manière qu'en cas d'élévation anormale de la température dans une zone de l'ouvrage, les buses (15) concernées s'ouvrent automatiquement et y projettent des jets continus sur les véhicules, engins, appareils, etc. qui s'y trouvent.
- Paroi selon la revendication 1, caractérisé par le fait que lesdits panneaux (10) sont formés chacun de deux plaques métalliques (11,12) limitant ledit espace fermé (13).
- Paroi selon la revendication 2, caractérisé par le fait que les deuxdites plaques (11,12) constituent les tranches d'une structure sandwich dont l'âme est formée par ledit espace (13).
- Paroi selon la revendication 2, caractérisé par le fait que lesdites buses (15) sont montées dans des ouvertures ménagées dans l'une des deux dites plaques (11,12)
- Paroi selon la revendication 2, caractérisé par le fait que lesdites plaques (11,12) présentent des formes offrant une bonne résistance mécanique à la pression du liquide et des moyens maintenant leur écartement pratiquement constant.
- Paroi selon la revendication 2, caractérisé par le fait que lesdites plaques (11,12) sont soudées bord à bord.
- Paroi selon la revendication 6, caractérisé par le fait que les deux plaques (11,12) sont reliées intérieurement par des ponts de soudure.
- Paroi selon l'une des revendications 1 à 7, caractérisée par le fait qu'elle est appliquée contre la surface du gros-oeuvre ( en béton ou autre.)
