Definitions

  • the present invention falls within the scope of making devices for performing an excavation such as for example, a railway tunnel, motorway tunnel or tunnel of other kind.
  • the present invention relates to a movable apparatus for positioning a centering for supporting and consolidating an excavation.
  • a centering comprises a plurality of metal elements connected to one another according to an archway configuration.
  • the arches of the centering consist of open profiles having an H-, C- or double T-shaped cross section.
  • the arches/elements of the centering may be tubular, having a circular, square, rectangular or triangular cross section.
  • the lateral arches typically comprise a support foot slidingly mounted at the free end and configured to be lowered to the ground so as to provide a support for the centering.
  • the elements forming the centering are connected to one another through flange connections, such as for example those described in EP 2354447 , or more favorably through suitable joining devices, such as that described in PCT/IB2015/054023 .
  • a device comprises a pair of elements, each connected to an end of a corresponding element of the centering.
  • Such elements have conjugated profiles so that one is inserted into the other so as to complete the joining between two adjacent centering arches.
  • the elements of the device are connected by a hinge. The latter allows the centering to be assembled by folding the lateral arches in order to facilitate the transport of the centering itself into the excavation.
  • the central arch of the centering is raised towards the crown, or upper wall of the excavation, through a fist lifting machine.
  • the lateral arches are raised by rotating outwards with respect to the central arch.
  • the lateral arches are rotated towards the side walls of the excavation by using further different movement/lifting machines from the machine that is lifting the centering. At the end of such a rotation, the centering is completely unfolded on a substantially vertical plane.
  • the arches of the centering are stably connected to one another through the joining devices indicated above. Then, the piers of the lateral arches are lowered through suitable equipment to provide two support points for the centering. At the end of this operation, all the arches of the centering are stably fixed to the excavation.

  • each centering After the assembly thereof and prior to the fixing to the excavation wall, each centering normally is connected to the adjacent one through connecting chains, the ends of which are hooked to corresponding supports welded along the arches of the centerings.
  • connecting chains Alternatively to the connecting chains, a more recent and more effective solution provides using connecting elements prepared on each centering and configured to be engaged in corresponding elements prepared on the adjacent centerings. An example of such connecting elements is described in PCT/IB2015/054022.

Such a subdivision is performed only for simplicity of description and is not to be considered as the real physical structure of the device. Rather, each module may be implemented as an electronic circuit on a suitable hardware support, as a routine software, a subroutine software or both. Each module may be integrated on a local unit or form part of a network. Such modules may also communicate with one another directly or through wireless protocols.

  • the acquisition module 50A transfers the information on the real position and orientation of the movement plane 501 detected by said further sensor means 52 to the processing module 50B.
  • the processing module 50B compares such information with the reference information (position/orientation of the plane of symmetry 300) stored in the memory module 50C. According to such a comparison, the processing module 50B sends signals to the control module 50D which actuates the movement means 77 of the movable means 5 to bring the deviation between the planes 501, 300 back to an acceptable value.
  • the control of the position/orientation of the movable means 5 is therefore preliminary to the successive raising of centering 2.

  • a centering 2 initially is resting on the ground and the two lateral arches 2B are folded inwards ( Fig. 5 ) by means of the hinges 8 mentioned above.
  • Apparatus 1 is moved close to centering 2. Once the position suitable for lifting is reached, the operator manually controls the first arm 11 to hook the central arch 2A through the related gripping means 32.
  • a first visual reference preferably is traced at the midplane of the central arch 2A. In this step, apparatus 1 is actuated in manual mode.
  • apparatus 1 may operate in manual mode or in automatic mode again.
  • the operator actuates the first arm 11 by acting on suitable manual controls.
  • the operator acts on the first actuating means 71, 72, 73, 74, 75 so as to raise the central arch 2A towards the crown on which a second visual reference preferably is traced.

  • the first sensor means 51 If the automatic mode is selected, once the gripping has been performed, the first sensor means 51 generate signals which are acquired by the acquisition module 50A. The latter transfers the information on the real topographic position of the central element 2A to the processing module 50B.
  • the processing module 50B compares such a real position with the reference position stored in the memory module 50C. According to the result of such a comparison, the processing module 50B sends control signals to the control module 50D which in a corresponding manner activates the actuators 71, 72, 73, 74 of the first arm 11.
  • the processing module 50B calculates, through suitable algorithms, the trajectory which each component of the first arm 11 should travel to bring the central arch 2A into the reference topographic position.

Once the descent of the support foot 2C is completed, the support foot 2C is locked to or automatically locks the corresponding lateral arch 2B in the position reached. Then actuator 90 is deactivated. It is worth noting that the use of push means of the side wall associated with the side arms 12, 13 of apparatus 1 substantially makes the adjustment of the position of the side walls automatic and therefore very fast.

  • the apparatus allows a fast and effective positioning of a consolidating centering without the need to use other movement machines.
  • the apparatus according to the invention allows the number of operators to be reduced and ensures better safety conditions.
