Definitions

  • This invention concerns a process to excavate the inverted lower arch in existing tunnels. To be more exact, this invention concerns a process suitable for the excavation and restoration of the inverted lower arch in existing tunnels without interrupting the flow of vehicles normally passing along the tunnels where work is to be done.
  • the process of the invention is generally employed equally well in work to enlarge existing tunnels or only repair the existing inverted arch.
  • the process may also be employed for the excavation and preparation of a new inverted arch in existing tunnels.
  • the invention concerns also the apparatus which employs the above process.
  • the state of the art covers the problems connected with the excavation and rehabilitation of the inverted lower arch in existing tunnels. These problems arise substantially from the need to interrupt any flow of vehicles within the tunnels until the excavation and rehabilitation work has been completed.
  • the outcome can be summed up as involving long times for design work and approval of the new plans, the necessity of expropriation of land, environmental problems and the unavoidable performance of new works upstream and downstream for the necessary rectification of the lay-out.
  • the present applicant has the purpose of overcoming the problems linked to the state of the art and of perfecting a process able to carry out the excavation and rehabilitation, or excavation and preparation, of the inverted arch in existing tunnels without interrupting the flow of vehicles passing into the tunnels.
  • a further purpose of the invention is to provide an apparatus able to carry out the above process.
  • the process of the invention provides for the use, within an existing tunnel, of a protective shield through which the traffic is made to pass.
  • This protective shield forms part of the state of the art.
  • the shield can stretch along the whole length of the tunnel or be restricted to the portion substantially affected by the works.
  • This portion in the case of a railway line, to which we shall refer in the description that follows, is suitably supported to enable trains to pass through while work is proceeding below it.
  • the support structures are suitable prepared on each occasion downstream of the portions on which work is being carried on, according to methods belonging to the state of the art.
  • the excavation works on the inverted arch are conducted with an apparatus which passes along the tunnel and is positioned between the protective hield and the inner wall of the tunnel.
  • This apparatus carries out the following works continuously for excavation and rehabilitation of an existing inverted arch: - the making of two lateral excavations parallel to the railway line so as to enable the apparatus itself to pass through; - excavation of the existing inverted arch for complete demolition of the same; - removal of debris of the excavated inverted arch from the excavation zone; - removal of all the excavation debris towards the outside of the tunnel or, at any rate, onto means able to carry the debris out of the tunnel, and - the casting of a new inverted arch.
  • the apparatus suitable to carry out the above process consists of a vault-wise structure bearing below itself the equipment to excavate the inverted arch.
  • This excavation equipment works beneath the railway line and comprises a rotary drum excavation tool that extends substantially along the whole width of the inverted arch.
  • this excavation tool carries on continuously the excavation of the inverted arch, the debris of which is removed by means of the excavation tool itself.
  • it comprises incorporated means for removal of debris from the excavated zone so as to transfer the debris onto means for final removal from the tunnel.
  • the excavation tool possesses not only a rotary motion but also a vertical motion so that it can be adjusted to the thickness of the inverted arch to be excavated.
  • Shuttering operates in cooperation with the excavation tool in a coordinated manner in the casting of material to form a new inverted arch in the excavation zone.
  • This shuttering is suitably conformed to constitute a support too for the railway lines above.
  • Auxiliary means may also be comprised to remove excavated material which may not have been collected by the excavation tool.
  • the vault-shaped structure is equipped with lateral excavation means to make channels parallel to the railway line which make possible the free forward movement of the excavation tool and the removal of debris from the tunnel; these lateral excavation means obviously work in advance of the excavation tool.
  • the apparatus of the invention can be included advantageously in a working train carrying out enlargement of existing tunnels; it can work just as well independently if only the repair of an inverted arch is required.
  • Provisional support means 14 to support rails 15, as in the state of the art, are provided in the zone involved in the excavation of an existing inverted arch 13.
  • provisional support means 14 which may consist of bundles of rails or other suitable systems, are positioned in succession along the railway lines 11-111 so as to enable the excavation work to advance continually.
  • the railway consisting of two lines 11-111 is protected by a protective shield 16 within which the trains 12-112 can pass.
  • the protective shield 16 may have a minimum indispensable length equal to the portion of the tunnel 10 involved in the works and may include its own runways 17 positioned on supports 18 arranged at the sides of the railway.
  • the protective shield 16 may also have a length differing from the portion of the tunnel 10 involved and will have overall dimensions suited to that of the trains 12-112 passing through it.
  • the apparatus to excavate the inverted arch 13 consists of a vault-shaped structure 19 able to run within the tunnel 10 on its own runways 20 positioned on supports 18.
  • the vault-shaped structure 19 comprises lateral arms 21 to support excavation equipment 22; these lateral arms 21 can be adjusted vertically, by jacks 23 for instance, so as to adapt the action of the excavation equipment 22 to the thickness of the inverted arch 13.
  • the vertical displacement of the arms 21 can be carried out continuously during the whole excavation work.
  • the excavation equipment 22 consists of a drum 24 capable of being rotated about its own axis according to the arrow 25 by a motor 26, advantageously a hydraulic motor.
  • the drum 24 extends substantially along the whole width of the inverted arch 13 and has an outer conformation suitable to obtain the desired final profile of the inverted arch 13 as an element to complete the circumference of the tunnel 10.
  • the outer conformation of the drum 24 conforms to a double cone.
  • the drum 24, which is hollow within, includes on its outside excavation tools 27, which cooperate with slits 28 made in the periphery of the drum 24 so as to enable the materail excavated to fall within the drum 24. This fall takes place by gravity and the material is held momentarily by vanes 29 suitably arranged inside the drum 24.
  • this discharge means is positioned parallel to the axis of the drum 24 and in this case is a first conveyor belt 30 driven by a motor 31 in the direction of the arrow 32.
  • At least one stationary worm is included within the drum 24 and is arranged in such a way that it skims the inner surface of the drum 24.
  • the excavated material is discharged sideways by the friction caused by the relative movements of the rotary drum and stationary worm. All embodiments provide for discharge of the material on one side or on the opposite side or on both sides.
  • the first conveyor belt 30 emerges laterally from the drum 24 and cooperates with a second conveyor belt 33 that removes the excavated material towards the outlet of the tunnel 10.
  • the second conveyor belt 33 being positioned beneath the plane of the railway lines 11-111, can cooperate conveniently with elements that discharge onto vehicles which carry the material out of the tunnel 10 if there is enough space available.
  • the lateral end portions of the drum 24 and of the first conveyor belt 30 and also the lower ends of the support arms 21 and the second conveyor belt 33 can move in service channels 34 excavated beforehand parallel to and at the sides of the railway. These service channels 34 are obtained advantageously by the action of excavation arms (not shown in the figures) solidly fixed to the vault-shaped structure 19.
  • Shuttering 36 works in cooperation and coordination with the movement of the excavation equipment 22 so as to make possible the casting of material 37 which will form the new inverted arch 113.
  • This shuttering 36 may be conformed advantageously to provide a support for the railway lines 11-111 above; for this purpose it may consist, for instance, of two halves 136-236 which can be coupled together telescopically and actuated by an inner screw 40.
  • a discharge worm screw 41 may be connected advantageously to the shuttering 36 and be suitable for lateral removal of debris not collected by the drum 24.
  • Fig.4 shows the situation in the zone where excavation work on a pre-existing inverted arch 13 takes place.
  • Fig.5 shows the situation after the new inverted arch 113 has been cast, together with the positioning of ballast 38, the arch 113 blending with the inner lining 39 of the tunnel 10.
