Definitions
- the present invention relates to a system for installing a service system in road tunnels.
- a first requirement is to guarantee that no water streams are generated in case of rain or water penetration of different kind and origin, especially through the joints of the vault of the tunnel, which may dangerously drip in the center of the carriageway.
- a second requirement is to periodically inspect the surface of the intrados of the tunnel in order to rapidly check the structural conditions and the presence of cracks and water infiltration points.
- Another requirement is to ensure the visibility of the walls of the tunnel for the drivers by means of the light emitted by the headlights of the motor vehicles, even when the tunnel is insufficiently and poorly lit.
- the walls of a tunnel must be coated, covering the concrete surface of the intrados.
- the most popular solution is to cover the two vertical sections of the intrados with a plurality of sheet metal panels, creating two continuous coating surfaces that extend on opposite sides until the base of the vault of the tunnel. Said panels are painted with light-reflecting paints that provide an efficient lighting of the tunnel as soon as they are hit by the light emitted by the headlights of the motor vehicles.
- said panels can hold the water infiltrations in the walls of the intrados and convey the water to the ground, in correspondence of suitable drainage channels provided on the two sides of the carriageway.
- the first drawback consists in the fact that the panels do not permit a rapid and frequent check of the structural conditions of the sides of the intrados because the sides are concealed on the back of the panels.
- the second drawback consists in the fact that the panels are not uniformly capable of receiving and correctly conveying the water streams produced through the vault of the tunnel, especially in correspondence of the joints of the intrados, towards the drainage channels provided in the ground.
- the provision and the installation of the painted panels have a high cost and difficulties may be encountered if said panels are to be mounted on an irregular surface of the intrados, adjusting to the radius of curvature of the intrados.
- JPS54176223 discloses a system for the installation of a service system in road tunnels according to the preamble of claim 1 .
- JP2018024978 discloses a concrete piece guard sheet capable of conveying water without freezing water leakage from a wall surface of a tunnel.
- JP2008019705 discloses a system to enable the easy visible inspection of the inside of a water guiding passage, without removing a leakage receiving plate.
- the purpose of the present invention is to remedy the drawbacks of the prior art by disclosing a system for the installation of a service system in road tunnels that is practical, inexpensive and capable of satisfying the management and maintenance requirements of a road tunnel.
- Another purpose of the invention is to disclose such a system for the installation of a service system in road tunnels that is reliable and efficient.
- the inventive idea of the present invention is to disclose an especially efficient, inexpensive system for the installation of a multi-functional service system inside road tunnels.
- Such a system provides for the installation of ducts on each one of the sides of a tunnel, said ducts being open on the back.
- Each duct can be mounted correspondingly to a joint provided between two portions of the concrete structure of the tunnel.
- Each duct is obtained from a plurality of concave sections that are fixed in projecting position to the intrados with concavity directed towards the intrados.
- the ducts are advantageously used for collecting and conveying the water leakage from the intrados of the tunnel and for providing an autonomous lighting of the road tunnel from the reflection of the light generated by the motor vehicles.
- Each duct is mounted in one of the joints of the tunnel, that is to say, in correspondence of an area with rainwater leakage. Therefore, the duct acts as a descending pipe of a gutter because it intercepts the water that leaks from the vault of the tunnel and conveys it by gravity towards an ending section suitably disposed at a slightly higher height than a rainwater drainage channel that is normally provided on each side of the carriageway of the tunnel.
- the system of the invention also comprises at least one gutter suitable for being disposed between two ducts in order to convey the water into a duct.
- the function of said horizontal gutters is to intercept any water stream that may drip from the vault of the road tunnel in the intermediate sections between two consecutive joints of the intrados.
- Said gutters are suitably inclined in such a way that the water can be drained towards a duct.
- the ducts leave the remaining surface of the road tunnel uncovered, thus permitting a rapid, easy check of the road tunnel on a periodical basis.
- the sections of the ducts can be made of sheet metal or extruded plastic materials.
- the sheet metal sections can be painted with light reflecting paints.
- the plastic sections are obtained from plastic materials that are intrinsically capable of reflecting the light emitted by the headlights of the motor vehicles. In both cases, the ducts made of reflecting sections can reflect the light of the headlights of the motor vehicles, thus providing an autonomous lighting of the tunnel.
- the section can have any length (or can be cut to measure from a piece of standard length).
- the operator in charge of installing the ducts can adjust the profile of the duct to the radius of curvature of the sides of the intrados.
- such an operation can be performed by sequentially installing a plurality of sections in inclined position, so that the duct can have a structure similar to a broken line that adjusts to the radius of curvature of the side of the intrados.
- the modularity of the sections allows for varying the total height of the ducts at will, according to the dimensions of the tunnel.
- the sections of the duct can be also used to install an electrically powered lighting system and a fire fighting system in the tunnel.
- the front surface of each duct can be used to install one or more rows of LEDs that are directed towards the motor vehicles and can be easily visible for the drivers.
- the sections of the duct have a concave shape, with concavity directed towards the intrados, that can be used for concealing the power supply cables used to supply the LEDs.
- Each duct can be used to install one or more water-spraying nozzles of a fire fighting system.
- a water supply pipe for said nozzles can be housed in a concealed manner on the back of the duct.

- the road tunnel (100) comprises a concrete structure (101 ) that generates a tunnel on a carriageway (103).
- the concrete structure (101 ) has an arch-shaped cross-section with two sides or intradoses (102) and a vault (104).
- the concrete structure (101 ) of the tunnel may comprise a plurality of portions that are joined by means of joints (J) that extend along a vertical plane.
- the system (200) of the invention comprises a plurality of sections (1 ) with a concave shape. Said sections (1 ) are fixed to the intrados (102) of the tunnel, being stacked one on top of the other with concavity directed towards the intrados, in such a way to generate a duct (C) for the flowing of water that substantially extends in vertical direction, in projecting position relative to the intrados (102).
- the duct (C) is disposed correspondingly to the joint (J) between two portions of the concrete structure (101 ) of the tunnel.
- each section (1 ) has a substantially V-shaped cross-section.
- the section (1 ) comprises a first wing (1 a) and a second wing (1 b) substantially disposed at 90° and joined in a longitudinal corner (1 c).
- the first and the second wing (1 a, 1 b) respectively have longitudinal bases (1a’, 1 b’) that lie on the same plane in order to be fixed to the intrados (102) of the tunnel.
- the first wing (1 a) is longer than the second wing (1 b).
- An angle of (a) of approximately 150° - 170° is provided between the first wing (1 a) and its longitudinal base (1 a’).
- An angle of (b) of approximately 100° - 130° is provided between the second wing (1 b) and its longitudinal base (1 b’).
- the two longitudinal bases (1 a’, 1 b’) of the section (1 ) are suitable for being brought in contact with the surface of the intrados (102) in such a way that the wings (1 a, 1 b) project from the intrados.
- the two longitudinal bases (1 a’, 1 b’) of the section (1 ) are provided with through holes suitable for being crossed by screw means (V) or other ordinary fixing means suitable for penetrating in the surface of the intrados (102).
- the section (1 ) has a longitudinal axis (L).
- the section (1 ) has a first end (10a) that is cut along an orthogonal plane to the longitudinal axis (L) of the section (1 ), and a second end (10b) provided with a V-shaped notch, in such a way to form a fork (F) between the first wing (1 a) and the second wing (1 b).
- the fork (F) has a vertex on the longitudinal corner (1 c) between the first and the second wing (1 a, 1 b).
- each section can be suitably disposed in order to perfectly adjust to the radius of curvature of the side of the tunnel.
- each duct (C) has the profile of a broken line and can perfectly adjust to the profile of the side of the tunnel.
- the duct (C) intercepts the water that drips from the vault of the road tunnel (100) and conveys it towards the sides of the tunnel into drainage ducts (CD) that are normally provided on the sides of the carriageway (103).
- the length of the first wing (1 a) of the section (1 ) is higher than the length of the second wing (1 b), in such a way that the first wing (1 a) is directed towards the traveling direction of the motor vehicles, as shown in Fig. 1 .
- a motor vehicle (V) travels in a lane of the carriageway, with reference to the intrados on the right-side of the motor vehicle, the motor vehicle firstly encounters the first wing and successively the second wing of the section. Because of such an assembly, the light of the headlights of the motor vehicles is reflected with higher efficacy in the first wing (1a) of the section (1).
- the light emitted by the headlights of the motor vehicle is reflected by the first wing (1a) towards the lane wherein the motor vehicle is traveling, thus lighting the road tunnel.
- the section (1) can be made of sheet metal or thermoplastic materials, and in any case with materials capable of reflecting the light of the headlights of the motor vehicles.
- the system (200) also comprises one or more gutters (2) suitable for being fixed to the intrados (101) in the space comprised between two ducts (C).
- the gutters (2) are preferably suitable for being mounted at different heights in parallel position in order to intercept all the water that drips from the vault.
- Each gutter (2) is disposed in a slightly inclined position relative to a horizontal plane, in such a way that the water intercepted by the gutter (2) flows towards a duct (C).
- each one of the ducts (C) can be also used for the installation of a plurality of LEDs and/or fire fighting nozzles.
- the space between the duct (C) and the intrados (102) can be used for the concealed installation of the power and/or water supply cables.
