Definitions

  • the present invention relates to a method for producing a concrete wall or wall cladding and, more particularly but not exclusively, to a method for producing a concrete cladding in an underground structure, as well as to an apparatus designed for the implementation of this process.
  • the concrete coverings of underground structures such as tunnels are generally made of vibrated concrete poured inside wooden or metal formwork.
  • Such a coating operation is fairly simple to carry out, but it turns out to be laborious because of the slowness of the stuffing operations of the masks and the time necessary for the hardening of the concrete which, for certain types of concrete, is at least 24 hours. . Because of this drawback, it is common in tunnels of large cross-section to use elaborate formwork of great length. However, such formwork is then expensive without being able to be quickly amortized.
  • the object of the present invention is to remedy the above-mentioned drawbacks of known methods, and for this purpose it proposes a method for producing a wall or a wall covering in concrete, and in particular a concrete covering. of an underground structure, as well as an apparatus designed for the implementation of this process, which while being very simple and very effective, turn out to be inexpensive, and harmless for the staff.
  • the method for producing a concrete wall or wall covering consists in placing a movable formwork opposite a bearing part for the wall or the wall covering, in introducing concrete inside the space provided between said support part and the formwork, then at move the said formwork in the direction of the length of the said support part by a distance substantially equal to the length of the previously concreted area, to carry out a new introduction of concrete, and to repeat this succession of operations until for producing the complete wall or the complete wall covering, and it is characterized in that, inside the space between the support part and the formwork, a quick setting concrete is sprayed, and in that the said displacement of the formwork takes place as soon as the sprayed concrete sets.
  • quick setting concrete concrete with a setting time of a few minutes or fractions of a minute.
  • the application of the method according to the invention to the production of a concrete wall or of a concrete wall covering in an underground structure is characterized in that the movable formwork is placed opposite a transverse portion of the length of the wall of the structure to be coated and has a profile corresponding to that of this transverse portion, in that the projection of quick-setting concrete takes place in the annular space formed between the formwork and said transverse portion of the length of the wall or between the formwork and the ground, and in that the displacement of the formwork after setting of the sprayed concrete takes place over a distance equal to the length of said transverse zone.
  • the apparatus for implementing the method according to the invention for coating an underground structure comprises a short formwork, mounted on a carriage movable in the direction of the longitudinal axis of the wall, the profile of the said formwork corresponding to the transverse profile of the wall to be coated, means for controlling the movement of the carriage, a rapid-setting robotic concrete spraying means associated with concrete and chemical admixture supply means, and control and guiding members selectively ensuring the movement of said mobile spraying means inside the annular chamber following the profile thereof, and a remote control cabin of the apparatus.
  • Said concrete projection means advantageously constituted by a lance, is robotized.
  • Appropriate control devices are provided to allow the correct continuity and compactness of filling to be checked.
  • a video camera makes it possible to control the good adequacy of the speed of displacement of the lance with the flow of shotcrete, in order to order a possible correction.
  • a cockpit can thus be kept at a distance, the occupant of which is protected from dust and toxic odors prevailing in the immediate vicinity of the formwork.
  • the structure of the formwork according to the invention is articulated and controlled by screw jacks so as to allow an adjustment of the geometry of its facing so that, by retraction, it can slightly separate it from the fresh concrete before moving the formwork .
  • the wall of a tunnel is shown at 1, the interior covering of which is desired, and at 2 the raft which has been made.
  • a carriage On rails 3 fixed to the raft 2 and oriented along the longitudinal axis of the tunnel, can move, by means of bogies 4, a carriage generally designated at 5.
  • the carriage 5 made up of a reticulated metal structure, has the shape of a gantry and is designed so as to axially provide a passage as large as possible for men and / or equipment.
  • This carriage 5 carries a formwork 6 of curved shape with a smooth outer surface, having at least two articulations 7 which allow its shape to be adjusted.
  • Hydraulic cylinders 8, 9 acting between the chassis of the carriage 5 and the formwork 6 allow fine adjustment, in lateral direction and in height, of the position of the formwork.
  • a concrete spray nozzle 10 with its accessories (not shown in the drawing) for supplying compressed air, concrete and various additives, is integral with an assembly comprising a hydraulic motor II and a toothed wheel 12 rotated by this motor.
  • the toothed wheel 12 is subject to a rack 13 fixed to the inner face of the formwork 6 so that, during the operation of the engine 11, the wheel 12 describes the rack 13 by moving the nozzle 10 for spraying concrete following the contour of the annular space 14 formed between the wall 1 and the formwork 6.
  • the main direction of filling of the annular space is parallel to the axis of the structure, and the nozzle 10 is introduced more or less deeply into the annular space 14.
  • the operation of the motor 11 and the supply of the nozzle 10 are then controlled so that the latter continuously describes the profile of the space 14 by spraying therewith quick setting concrete.
  • the operator controls the stopping of the supply and the displacement of the nozzle 10 then as soon as the concrete is set , that is to say after a few minutes, it controls the movement of the carriage 5 along the rails 3 of a length L equal to that of the pass made, then proceeds to a new projection operation of concrete.
  • the formwork 6 is slightly retracted by means of the jacks 8, 9 so as to separate it from the fresh concrete, so as not to degrade the smoothing. or the compactness of the coating installed.
  • the hydraulic registration of the formwork 6 is carried out automatically.
  • Appropriate control devices carried by the device make it possible to check the correct continuity and compactness of the filling.
  • a video camera (not shown) makes it possible to remotely control the adequacy between the speed of movement of the nozzle 10 and the flow of shotcrete, with a view to possible correction.
  • the cockpit is advantageously kept at a distance and an additional direct control can be carried out by the operator before moving the truck.
  • the movement of the carriage 5 is remotely controlled from the cockpit, which is closed, self-propelled and with high visibility.
  • the first phase of the above-mentioned process producing a continuous thin hull in coffered sprayed concrete, can also be implemented to obtain, in uncoated tunnels, thin concrete hulls to protect vehicles from falling blocks stone or water inlets.
  • a flat formwork 15 is kept vertical, and resting on the edges of the wall to be constructed, by the hydraulic arms 16 of a machine (not shown) such as a hydraulic shovel mounted on tracks.
  • the front lateral end of the formwork 15 is equipped with an endless chain 17 on which is fixed the end of a lance 18 for spraying concrete.
  • the nozzle 19 fitted to the end of the lance 18 is bent to enter the space 20 formed between the formwork 15 and the excavation wall.
  • a slide 21 is fixed to the excavation wall, above the area of realization of the wall, and the formwork 15 is suspended from this slide 21 by an articulated console 22.
  • the length of the slide 21 is a few meters and corresponds to the length of travel of the arms 16 for a fixed position of the hydraulic shovel.
  • the displacement and guidance system of the projection nozzle has been described as consisting of a toothed wheel meshing with a rack integral with the formwork, but that this displacement and guidance system could have any equivalent structure . It could for example include a carriage carrying the projection nozzle and moving along the profile of the formwork by means of a double cable with end winding winch. It will also be understood that the carriage 5 has been described as moving on rails via bogies, but that any equivalent means could be used. Thus, if the raft has not been previously made, provision can be made to move the carriage 5 from an overhead crane on a cable or a suspended rail.
