Definitions

  • the subject of the present invention is an installation for making a buried wall by mixing the ground with a binder allowing a correction of trajectory and a method for correcting the trajectory of the drill head of such an installation.
  • diaphragm walls which consists, using a drilling machine such as a hydrofraise, to achieve successively in the ground trench portions and to fill the trench thus produced with a cement or a concrete .
  • This technique which consists of mixing the cut soil to make the trench with the binder is known as the Anglo-Saxon soil mixing.
  • the installation 10 comprises a mobile frame 12 on which is mounted a vertical guide mast 14.
  • a translational movement head 16 can slide along the vertical mast 14 to drive in turn, in the vertical direction, a guide beam 18.
  • a guide beam is commonly called “kelly” by those skilled in the art. It is therefore this term that will be used in the rest of the text.
  • a drilling and mixing head 20 At the lower end 18a of the kelly 18 is mounted a drilling and mixing head 20 of the type known per se.
  • the drill head 20 is rigidly attached to the lower end 18a of the kelly 18 and essentially consists of two sets of rotating tools 22 and 24 rotating about horizontal parallel axes when using the machine. These rotary tools allow both the cutting of the soil to make the trench corresponding to the wall to be made and the mixture of the binder or cement with the ground thus cut.
  • the binder or cement is injected through a tubing 26 which passes through the kelly 18.
  • the kelly 18 transmits to the drilling and mixing head 20 the thrust exerted by the displacement head 16 guided by the mast. Being guided along a mast placed in a vertical position thanks to a certain rigidity, the kelly participates in driving the tool along a vertical axis.
  • a certain rigidity of torsion makes it possible to resist risks of twisting of the kelly and thus of the drilling and mixing head.
  • the assembly on kelly allows a correction of the deviations in the direction perpendicular to the common axis of rotation of the rotary tools by adjusting differential speeds between the right and left motors controlling the rotary tools.
  • this arrangement does not make it possible to correct deviations corresponding to a kinking or a deflection in the direction of the axes of rotation of the rotary tools.
  • a first object of the invention is to provide an installation for producing a buried wall by mixing soil / binder that allows trajectory corrections along the three axes of orthogonal coordinates.
  • the installation is characterized in that it further comprises controllable mechanical means mounted at the lower end of said kelly to cause an angulation relative to the vertical of said drilling and mixing head at least about an axis substantially orthogonal to said direction YY ', whereby the trajectory of the drilling and mixing head can be corrected.
  • controllable mechanical means comprise means forming a pivot axis between the lower end of the kelly and said drilling and mixing head extending in a direction XX 'substantially orthogonal to the direction YY and means for controlling the pivoting of said head about said axis.
  • the drilling and mixing head comprises two distinct parts juxtaposed and each mounted on said pivot axis, each part comprising a rotary tool, the axes of the rotary tools being parallel to each other when the two parts of the drilling and mixing head are aligned, and each part having its own pivot control means.
  • said drilling and mixing head is rigidly fixed to the lower end of the kelly and the controllable mechanical means comprise two substantially identical flaps mounted on either side of the lower end of the kelly. to be able to pivot about a common geometric axis substantially orthogonal to said direction YY ', and control means of said flaps about said common axis.
  • the two flaps symmetrically mounted on the lower end of the kelly will, by a dynamic action, allow, thanks to their controlled orientation, to obtain a deviation of the lower end of the kelly by a certain bending thereof and thus the drilling and mixing head.
  • each drilling tool is constituted by two coaxial cutters 22a and 22b arranged from and the other of the plate 32.
  • the elements such as 34 mounted on the strawberries have a suitable shape for carrying out both the cutting of the soil and the mixing of the soil with the binder.
  • the fixing plate 30 of the head 20 is connected to the lower end 18a of the kelly 18 by a pivoting system 36.
  • the pivoting system essentially consists of an axis 38 which extends along the direction XX 'orthogonal to the general direction of the kelly and the axes YY' of rotation of the rotary tools.
  • the shaft 38 is mounted in bearings carried respectively by lugs 40 extending the lower end 18a of the kelly and by non-visible bearings integral with the fixing plate 30.
  • the pivoting system 36 also comprises means for rotating the head 20 with respect to the end 18a of the kelly around the axis 38.
  • these control means are constituted by two jacks 42 and 44, one of which end is articulated on the attachment plate 30 of the head 20 and the other end is articulated on the lower end of the kelly 18.
  • the cylinders 42 and 44 By controlling the cylinders 42 and 44, it is thus possible to control the angulation of the head 20 relative to the vertical axis XX 'defined by the axis 38.
  • the cylinders are hydraulic and their control system is disposed at the lower end of the kelly 18.
  • the drilling and mixing head which bears the reference 20 'is constituted by two distinct parts 110 and 112.
  • Each part comprises a half-plate 32a, 32b symmetrical and independent of one another.
  • On each half-plate 32a, 32b are mounted two drilling tools 22a, 22b respectively constituting the drilling tools 22 and 24.
  • each half-plate 32a, 32b is pivotally mounted about the pivot axis 38 mounted at the lower end of the kelly 18.
  • Each half-plate 32a, 32b is secured to one end of one of the cylinders 42 and 44. Cylinders 42 and 44 can be ordered separately. It is thus possible to give the two drilling tools 22 and 24 angulations that are opposite to the longitudinal direction of the kelly 18. This configuration makes it possible to correct kelly twist.
  • the drilling and mixing head 20 which is identical in all respects to that described in connection with FIGS. 2 and 3 is directly bolted by its fixing plate 30 to the lower end 18a.
  • kelly thus obtaining a connection as rigid as possible between the kelly 18 and the head 20.
  • the portion of the kelly near its lower end 18a, and more precisely in its zone 18b, is equipped with two identical flaps 50 and 52 which are pivotally mounted about a geometric axis xx 'which is orthogonal to the axes of rotation of the rotary tools 22 and 24.
  • FIG 8 there is shown in detail a first mounting mode of the flaps 50 and 52 on the portion 18b of the kelly.
  • the flaps 50 and 52 are integral with a common axis of rotation 54 which passes through the walls of the kelly by bearings 56 and 58.
  • the flaps 50 and 52 which, at rest, are vertical, are symmetrical with respect to the geometric axis xx 'defined by the axis of rotation 54.
  • Inside the kelly are provided means for controlling the rotation of the flaps 50 and 52.
  • These control means may consist of a motor, for example a hydraulic motor 60 of which output shaft drives a first gear 62 meshing with a second gear 64 integral with the pivot axis 54.
  • the two flaps 50 and 52 are the same pivot angle.
  • the motor 60 is controlled from the surface.
  • FIG. 9 shows a second method of mounting the flaps 50 and 52 on the portion 18b of the kelly, the flaps being identical to those shown in FIG. 6.
  • each flap is mounted on a half pivot shaft respectively 70 and 72 which passes through the wall of the kelly 18 by bearings 56 and 58.
  • Each rotating half-shaft 70 and 72 is driven by a specific motor 74 and 76 via a train gears 78 and 80.
  • flaps can be oriented independently, it is understood that these flaps not only make it possible to correct a trajectory error in the direction XX 'of the rotational axes of the rotary tools, but also of the trajectory errors due to kelly twisting, this twisting being corrected by giving different orientations to the shutters 50 and 52.
  • the flaps 50 and 52 act as a boat rudder or elevator of a "duck plane" plane in the non-solid material that fills the trench being excavated. So that properly oriented shutters can produce their deviation effect, especially given the density of the material that fills the trench, it is necessary that the flaps, that is to say the assembly consisting of the kelly and the head 20, have a certain speed.
  • FIG. 10a there is shown the trench 100 being drilled, the lower end 102 of the trench being deflected.
  • This figure also schematically shows the material 104 filling the trench and constituted by the mixture of cut soil and binder.
  • the kelly 18 / head assembly 20 is raised in the trench of sufficient height as shown in FIG. 8b.
  • the flaps 50 and 52 are suitably oriented to correct the deflection of the previously detected drill bit. After the correct orientation of the flaps, using the guide mast, it controls the descent of the kelly 18 / head 20 with a suitable controlled speed. If the length of the stroke and the linear speed of displacement of the kelly 18 are suitable, the flaps 50 and 52 play their role of deflecting the lower end of the kelly and thus of the head 20.
