Abstract

A survival module for a one-way double barrel tunnel comprises, within a tunnel double barrel joining duct (2), a chamber including, at end portions thereof, an access prefabricated structure (10) having inlet and outlet doors (11,12) arranged adjoining an electric apparatus storing closed space (13), a cylindric body (20) including a fan (21) and a related fire barrier gate (22) being arranged on the top of said closed space.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a survival module for one-way double barrel tunnels.
As is known, one-way double barrel tunnels conventionally comprise, at preset spacings, joining ducts which operate to allow an evacuation from a tunnel barrel to the other tunnel barrel, as, for any reasons, dangerous condition occur.
To that end, at the joining duct, it is necessary to provide a plurality of separating regions with openable openings to allow pedestrian and, in same cases, also vehicular crossings.
Prior solutions for meeting the above requirements provide to make very complex structures which are made, as necessary, in situ, without making criteria allowing to provide standard solutions and an optimum operation thereof.

SUMMARY OF THE INVENTION

Accordingly, the aim of the present invention is to solve the above mentioned problem, by providing a survival module for one-way double barrel tunnels, which may be prefabricated and easily and quickly installed, thereby allowing related safety criteria to be standardized.
Within the scope of the above mentioned aim, a main object of the invention is to provide such a survival module allowing to form, in a very easy and practical manner, a region safely separated from dangerous zones in one of the tunnel barrels, thereby allowing the users both to quickly evacuate the dangerous region and to resist against high temperatures.
Another object of the present invention is to provide such a survival module which, owing to its specifically designed constructional features, is very reliable and safe in operation.
Another object of the present invention is to provide such a survival module which can be easily made starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a survival module for one-way double barrel tunnels, characterized in that said survival module comprises, within a joining duct for joining a double-barrel tunnel, a chamber comprising, at end portions thereof, an access prefabricated structure with an inlet door and an outlet door arranged adjoining an electric apparatus storing closed space, above said closed space a cylindric body including a fan and related fire barrier gate being arranged.

BRIEF DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the number references of the above mentioned figures, the survival module for one-way double barrel tunnels, according to the present invention, comprises a module chamber, schematically indicated by the reference number 1, formed in a joining duct 2 arranged between the one-way barrels or tubes 3 and 4 of a double-barrel tunnel.
According to the invention said chamber comprises, at each end portion thereof, a prefabricated structure, generally indicated by the reference number 10, which includes an inlet door 11 and an outlet door 12 which are arranged adjoining a closed space 13 which may be used for storing or recovering electric apparatus therein.
Above the closed space 13 a cylindric body 20 including a fan 21 interconnected to a fire barrier gate 22 is provided.
In said prefabricated structure 10 it is further possible to provide a series of safety elements comprising a video camera 30 for monitoring the encompassing environment, a fume detector 31 and an environment pressure switch 32.
Moreover, a fitting sleeve 5 adjoining the fan 21 and a hot wire flow-meter 35 are also provided.
On the front of the above structure are furthermore arranged an asymmetric projector 40 and a closed space interface 41 cooperating with an intercommunication audio system 42.
The prefabricated structures 10, for an exclusively walking-on duct, are arranged in a front framework, generally indicated by the reference number 15, operating as a duct encompassing and closing element.
For a walking-on and carriageable duct, said structures 10 are coupled to one another by concrete coupling walls 16 which, at a middle portion thereof, comprise adjoining walls 16 including openable doors for allowing emergency means or vehicles to pass therethrough.
From the above disclosure it should be apparent that the invention fully achieves the intended aim and objects.
In particular, the fact is to be pointed out that the invention provides a safety structure including therein all the necessary safety elements, thereby greatly facilitating the installation operations and providing optimum standardized safety.
The invention, as disclosed, is susceptible to several modifications and variations, all of which will come within the scope of the invention.
Moreover, all of the constructional details can be replaced by other technically equivalent elements.
In practicing the invention, the used materials, provided that they are compatible to be intended use, as well as the contingent size and shapes, can be any, depending on requirements.
