The front part of the mould is connected to a traction unit, by means of a chassis, said traction unit comprising caterpillar treads and columns for levelling the mould. The interior of the mould houses vibrators for compacting the concrete. The aforementioned chassis includes automatic levelling means comprising two or more hydraulic columns which are controlled by sensors that are disposed on both sides of the tunnel. The invention is particularly suitable for concreting the sills of tunnels on high-speed railway lines. In addition, the device can be used for the automatic concreting of the entire width of the tunnel, thereby automatically maintaining the pre-established horizontal and superelevation values.

Description

    Technical field of the invention
  • The present invention relates to a device for spreading sill concrete in railway tunnels.
    • Background of the invention
  • Tram and railway tunnels, particularly those of high-speed lines, are generally of circular cross section and eight metres wide. For this reason, a special device with the following functionality must be used to concrete the entire width of the surface: end-to-end concreting, concreting with superelevated slabs and compensation of irregularities produced by the tunnel-boring machine.
  • In general, the machines that are known to carry out these functionalities have concreting moulds located between the caterpillar treads, due to which it is not possible to concrete the entire width of the tunnel, representing an inconvenience, particularly when the entire width of the tunnel must be concreted.
  • The object of the present invention is to provide a device for spreading sill concrete in railway tunnels, based on a new concept and functionality, essentially characterized in that it comprises a transversely-extending mould which is used to form the concrete sill, connected by its front part, by means of a chassis, to a traction unit comprising caterpillar treads and columns for levelling the mould.
  • According to another characteristic of the present invention, the mould is disposed in the rear part of the device, in its direction of movement, out of reach of the caterpillar treads.
  • According to another characteristic of the present invention, the device includes concrete feeding means comprising transport means to transport the concrete from the front part of the device towards the mould.
  • In such case, the transport means shall preferably include an endless conveyor belt.
  • According to another characteristic of the invention, the device comprises vibrators adapted to compacting the sill concrete housed inside the mould.
  • Said vibrators shall preferably be disposed in series distributed heightwise, so that these start up based on the height or thickness of the concrete sill.
  • According to another characteristic of the present invention, the chassis includes automatic levelling means comprising two or more hydraulic columns which are controlled by sensors located on both sides of the tunnel.
  • According to a preferred embodiment of the present invention, the mould extends transversely.
  • In this case, the mould is comprised of two collateral halves, disposed in the direction of movement of the device, each of which has a corresponding hydraulic cylinder for actuating its extension and retraction.
  • Preferably, the device shall comprise means to control the mould's transverse extension, in order to adapt the mould's width to that of the internal tunnel cavity, in addition to end limit sensors with feelers, the feedback of which is used to control the cylinders.
    • Brief description of the drawings
  • The accompanying drawings illustrate, by way of non-limitative example, a form of embodiment of a device for spreading sill concrete in the railway tunnels of the present invention. In said drawings:
    • Fig. 1
    shows an elevational side view of a preferred embodiment of the device of the present invention; and
    Fig. 2
    shows a plan view of the device shown in Fig. 1.
    Detailed description of the drawings
  • Said drawings indicate that the device or machine (100) comprises a mould (1) for concreting the tram or railway line receiving sill (9) inside a tunnel. Movement of the device (100) is produced towards the left side, as shown in the drawings and indicated by means of arrows in both figures.
  • The mould (1) extends transversely so as to be able to concrete the entire width of the tunnel and adapt to the variations in width thereof, resulting from the irregularities produced by the tunnel-boring machine (100), with the object of constructing a sill (9) for the lines, defined according to a pre-established layout in terms of levels, horizontalities and superelevations in curves. The transverse extension and retraction of the mould (1) is actuated by means of two hydraulic cylinders (17', 17") (Fig. 1), each of which is adapted to extending the corresponding half (1', 1") of the mould (1). The halves (1', 1") are disposed on either side of the tunnel-boring machine or device (100) and actuated independently, so as to correspond to different profiles on both sides in the direction of movement of said machine or device (100).
  • The device is transported by caterpillar treads (4) and the mould (1) is installed in the rear part of the device (100), as opposed to conventional machines of this type, in which the mould is disposed between the treads.
  • As the mould (1) is installed out of reach of the caterpillar treads (4), these do not limit the transverse extension of said mould (1), so that it can fully cover the desired width of the tunnel sill (9).
  • For this purpose, the mould (1) includes endless bands (13) for horizontal and transverse movement, which allow the concrete to be distributed throughout the entire width of the tunnel.
  • The caterpillar treads (4) laterally support levelling columns or hydraulic cylinders (5, 6 and 7), the piston rods of which are solidly joined to a chassis (2), in such a way that the position and orientation of said chassis (2) depend on the relative and absolute elongation of the cylinders (5, 6 and 7). The mould (1) is also solidly joined to the chassis (2), in such way that its position and orientation consequently depend on the position and orientation of the chassis (2).
  • One of the caterpillar treads carries two columns (6 and 7), while the other only carries one column (5). Said columns (5, 6 and 7), which are controlled by sensors (11, 12) installed on either side of the tunnel, house a hydraulic cylinder for levelling the machine. Two of the sensors (11), such as those on one side of Fig. 2, can be levelling sensors, while the sensors (12) on the opposite side could be direction sensors.
  • The machine (100) can therefore be operated automatically, its movement being controlled in accordance with the signs received by the sensors (12) that actuate the absolute and relative speed of the caterpillar treads (4).The height and angles of the mould (1), relative to the horizontal and vertical planes, vary in accordance with the extension of the cylinders (5, 6 and 7), which is controlled by the levelling signs received by the sensors (11).
  • The lateral extensibility of the mould (1) allows the sill (9) to be constructed to the desired level within the tunnel, adapting to the varying widths of the corresponding level resulting from layout irregularities, normally slight but nonetheless visible in high-speed lines, produced during tunnel boring.
  • For this purpose, some of the sensors (11, 12) can be of the end-limit sensor type, in order to feed back the extension-retraction of the cylinders (17', 17") that actuate each half (1', 1") of the mould (1).
  • In order to feed the concrete, the chassis (2) comprises an endless conveyor belt (14) that collects the concrete, for example from a loading hopper (14), and pours it into the form (15) of the mould (1). The interior of the mould (1) houses vibrators (8, 8') for compacting the concrete. Fig. 1 shows how said vibrators (8, 8') are disposed in series distributed heightwise, so that these start up based on the height or thickness of the concrete sill (9).
  • The present invention allows sills (9) of varying widths ranging from 4.0 to 6.0 metres to be constructed using a machine (100) with, for example, caterpillar treads spaced 2.5 metres apart.
  • Having sufficiently described the nature of the present invention, in addition to its implementation, we hereby state that, anything which does not alter, change or modify its fundamental principle, shall be subject to variations in detail.
  • Obviously, the device of the present invention could be applied to the construction of sills in tunnels for other applications, all of which is also included under the protection of the present invention.
