Definitions

  • the present invention relates to a hydraulic circuit for the downflow of water from a tunnel, in particular water of a fire fighting plant.
  • a hydraulic circuit comprising a plurality of siphons, which are distributed along the tunnel, are mounted below a tunnel roadway, and are adapted to receive the water on the roadway itself and to prevent the introduction into the tunnel of toxic gases generated by possible combustion phenomena which may occur along the hydraulic circuit.
  • the siphons are connected in parallel to one another and to a collection header which extends along the tunnel, is mounted below the siphons, and is connected to each siphon by means of a corresponding coupling pipe.
  • numeral 1 indicates as a whole a tunnel, which has a roadway 2 for the circulation of motor vehicles (not shown), is provided with a fire fighting plant (of known type and not shown), and is further provided with a hydraulic circuit 3 for the downflow of water from the roadway 2 itself, in particular water for the mentioned fire fighting plant.
  • tunnel 1 may obviously be used for uses different from that described above, e.g. as a railway tunnel.
  • Circuit 3 comprises a plurality of siphons 4, which are evenly distributed along the tunnel 1, are mounted below the roadway 2, communicate with the roadway 2 for receiving the water on the roadway 2 itself, and are connected in series to one another.
  • each siphon 4 comprises a lower box-like body 5 and an upper box-like body 6 mounted on the body 5 itself.
  • the body 5 is substantially U-shaped, and comprises two arms 7 substantially parallel to each other, which extend upwards from a connecting crosspiece 8 which is substantially transversal to the arms 7.
  • Each arm 7 has a side outlet 9, which extends transversally to the arm 7 itself, is aligned and coaxial to the outlet 9 of the other arm 7, and is fluid-tightly coupled to a corrugated pipe 10, which is inserted within the outlet 9 by interposing an annular seal (not shown) blocked inside a groove of the pipe 10 itself, and allows to connect the corresponding siphon 4 to an adjacent siphon 4 or to a collection device (not shown) for the water evacuated from the tunnel 1 by means of the circuit 3.
  • Each arm 7 further comprises an upper sleeve 11 which protrudes upwards from the arm 7, hydraulically communicates with the arm 7, and has a lower narrow portion 11a and an upper expanded portion 11b.
  • the crosspiece 8 has a maximum filling level L1 lower than a minimum inlet level L2 of water in the two outlets 9, and is provided with a central inlet 12 which allows to let water into the body 5, protrudes upwards from the crosspiece 8, extends between the arms 7 parallel to the arms 7 themselves, and comprises a lower narrow portion 12a and an upper expanded portion 12b.
  • the body 6 is substantially T-shaped, communicates with the roadway 2 for receiving the water on the roadway 2, its top is closed by a grid 13 which is substantially coplanar with the roadway 2 itself, and is provided with a lower central tang 14 which is fluid-tightly coupled to the outlet 12, and is inserted into the portion 12b by interposing an annular seal 15.
  • Body 6 further comprises two tubular appendixes 16, which protrude downwards from the body 6 parallelly to the tang 14, and are arranged on opposite sides of the tang 14 itself.
  • Each appendix 16 has a lower end inserted into the portion 11b of a corresponding sleeve 11 and is fluid-tightly coupled to the sleeve 11 itself by interposing an annular seal 17, and further has an upper end which hydraulically communicates with the body 6, and is closed by an extractable plug 18 adapted to allow the body 5 to be inspected.
  • the hydraulic circuit 3 has some advantages mainly deriving from that the connection in series of the siphons 4 implies making a single, relatively shallow excavation, requires relatively simple, fast maintenance interventions in case of breakage of siphons 4 and/or pipes 10, and prevents flames and toxic gases generated by the possible combustion of flammable liquids within one of pipes 10 from propagating into the whole circuit 3.
