Definitions

  • the present invention relates to a drilling tool for producing walls in the soil resulting from mixing the cut soil and an additional binder.
  • On-site mixing techniques of soil drilled to a hydraulic binder are now widely used to improve foundation soils.
  • the tools used generally implement specific equipment resembling augers rotated along a vertical axis. These machines make it possible to produce rectangular wall elements by juxtaposing several augers, which leads to using high power machines when the trench must reach depths greater than 10 m.
  • this mixture must be left in place in the trench in progress in order to obtain a thin wall in the soil resulting from the setting of the ground mixture-hydraulic binder, wall whose shape is defined by that of the trench .
  • This machine consists essentially of two pairs of cutters mounted on a support structure. Each pair of cutters is connected to a hydraulic motor. These motors are housed in a relatively large box arranged above strawberries.
  • the box in which the motors are mounted has a relatively large apparent surface.
  • the presence of this box of large size considerably hinders the ascent of the tooling after the mixing has been carried out since the box must "make its way” into the kneaded material consisting of soil cuttings and hydraulic binder.
  • the presence of this box can promote the blocking of the machine in the panel filled with the mixture consisting of drill cuttings and hydraulic binder, during its ascent.
  • the two pairs of cutters being driven from the same motor, all the cutters have the same speed of rotation. However, in some cases, it is interesting to be able to give each pair of cutters a different speed of rotation, in particular to correct vertical defects during the digging of the trench.
  • the power of the motor is distributed between the two pairs of milling cutters in normal operation. On the other hand, if one pair of milling cutters hangs, the entire motor power must be supported by the other pair of milling cutters. This therefore requires a mechanical dimensionnemeht of the system that takes this situation into account.
  • Excavation machines are also known for making trenches in the ground. These machines are most often constituted by two pairs of rotary cutters mounted at the lower end of a large frame. The upper end of the frame is integral with levitation means which are generally constituted by cables.
  • the frame of the machine has a generally rectangular shape whose dimensions are substantially equal to the overall dimensions of the pairs of strawberries.
  • the dimensions of the cross section of the frame are substantially equal to those of the horizontal section of the trench portion which allows the machine to be made during its downward movement.
  • the walls of the frame are substantially in contact with the walls of the trench portion being produced which ensures the vertical guidance of the machine to obtain a trench portion also substantially vertical.
  • the land cut by the cutters is discharged by a suction pipe whose suction mouth is disposed between the walls of strawberries below the frame.
  • the present invention relates to a drilling tool of this type which avoids the two disadvantages mentioned above.
  • the drilling tool comprises the features of claim 1.
  • the tooling does not include a box containing the motor or bulky transmission systems. Furthermore, each motor can be controlled independently and give each pair of cutters a different speed of rotation. Because there is no box above the cutters tooling, it is understood that the rise of the tool in the mixture cuttings / hydraulic binder is greatly promoted. This ascent is made even easier by the particular shape of the support structure of which only the edge is likely to oppose the raising of the drilling tool, or this edge has reduced dimensions and has a suitable shape.
  • the motors are hydraulic and the tooling further comprises feed pipe assemblies of said motors consisting of holes in the thickness of the shell of the support structure.
  • these supply lines are fully disposed within the plate and can not oppose the recovery of the tool after the completion of the trench and the mixing of cuttings with the hydraulic binder.
  • the upper edge of the plate of the support means is tapered. This further promotes the recovery of the drilling tool through the mixture cuttings drilling / hydraulic binder.
  • the levitation means comprise at least one guide portion whose lower end is directly integral with the flange of the support structure.
  • the dimensions of the flange, which is horizontal, are substantially equal to that of the cross section of the guide beam.
  • the flange is only an extension of the guide portion and therefore does not oppose this rise.
  • the thickness of the guide beam, in the direction of the axes of rotation of the cutters is less than half the length of the axis of rotation of a pair of milling cutters and the width of the section of the Guiding beam is less than one third of the size of the two pairs of milling cutters in the horizontal direction perpendicular to said axis of rotation.
  • FIG. 1 there is shown a drilling machine using the drilling tool according to the invention.
  • the tooling 12 is guided in the trench by a guide beam 14 of constant profile and preferably of rectangular cross section. Tooling 12 is attached to the lower end 14a of the beam.
  • the guide beam 14 makes it possible to transmit the thrust and traction forces on the tooling 12. It also makes it possible to protect the supply lines of the tooling by hydraulic binding, as well as the power supply lines of the motors. rotating the strawberries.
  • the guide beam 14 is connected by guiding and driving means 16, 18 to a vertical mast 20.
  • the mast is supported by a crawler carrier 22 on which a hydraulic power generation system 24 is installed.
  • the tool 12 is moved vertically in the ground to make a trench panel by drilling the soil and mixing the cuttings with the hydraulic binder. .
  • the guide beam 14 is shown at the lower end 14a of which the drilling tool itself is fastened.
  • This drilling tool consists of two pairs of milling cutters 26, 28, 30, 32, the milling cutters. the same pair being coaxial and the axes of rotation of the cutters being parallel and substantially horizontal in use.
  • the motors for rotating the cutters 26 to 32 are arranged inside the burs themselves, which avoids having to provide an external motor of training of these strawberries.
  • the pairs of cutters 26 to 32 are connected to the lower end 14a of the guide beam by a support structure bearing the general reference 34.
  • the support structure 34 may be equipped with scraping systems 36 which allow when the soil is sticky, remove the soil that adheres to the strawberries between their teeth 38.
  • the support structure 34 is constituted firstly by a plate 40 which consists, in the particular embodiment described, in two half-plates 42 and 44 connected to each other by a triangular piece 46 connecting the two half-plates 42 and 44. to a fastening flange 48 for securing the support structure 34 with the lower end 14a of the guide beam.
  • This flange 48 is of course substantially horizontal and therefore orthogonal to the half-plates 42 and 44.
  • the fastening flange has substantially the same dimensions as the horizontal cross section of the guide beam 14.
  • the lower ends 44a , 42a of the half-plates are equipped on each of their faces with pairs of coaxial cylindrical ferrules 50, 52 and 54, 56. These ferrules whose X, X 'and Y, Y' axes are orthogonal to the half-plates 42 and 44 are used on the one hand for mounting the hydraulic motors and on the other hand for guiding in rotation the drums on which the strawberries themselves are mounted.
  • the guide beam 14 in horizontal cross section, dimensions which are very small compared to those of the drilling tool 12 and therefore compared to those of drilling performed by the tool.
  • the thickness I of the flange 48 is less than half the length H (see figure 4 ) of the axis of a wall of the cutters 26 to 32.
  • the width I (see figure 5 ) of the flange 48 is less than one third of the length L (see figure 4 ) of the drilling tool 12, that is to say of its maximum size in a horizontal plane.
  • the upper edge or edge 44b, 42b of each half-plate has a first portion 44c, 42c which is substantially horizontal and of reduced length and downwardly inclined portions 44d, 42d which constitute the sides of a triangle of which the top would be disposed towards the flange 48. More preferably, the edges or slices 42b, 44b of the half-plates 42 and 44 are beveled as best shown in FIG. figure 4 .
  • the upper edge of the plate 40 has a shape that promotes the rise of the drilling tool in the cut soil mixture / hydraulic binder contained in the trench.
  • the rotary milling motors of cutters are preferably hydraulic motors.
  • the power fluid supply pipes are constituted by holes such as 58 and 60 made in the thickness of the half-plates 42 and 44.
  • the upper end of the pipes 58, 60 opens into holes such as 62 in the flange 48 for connecting the pipes 58 and 60 to the power fluid supply pipes disposed in the guide beam 14.
  • scraping systems 36 are fixed on either side of the central triangular piece 46 of the support means 34. These scraping systems 36 comprise scraping pieces such as 64 which are nested. between the rows of teeth 38, 38 ', 38 "strawberries to remove the soil that could adhere to strawberries between these teeth.
  • scraping systems 36 have a profile that promotes the raising of the drill bit into the cuttings / hydraulic binder.
  • Hydraulic motors such as 70 which are fixed in the shells 50 to 56 are first shown.
  • the output shafts of the motors 70 are connected. mechanically in rotation and in translation to drums such as 72 on which are mounted the actual burs 30-36 with their teeth 38, 38 'and 38 ".
  • the ends of the hydraulic fluid supply pipes 58 and 60 are connected by any suitable means to the system supply of hydraulic motors 70.
  • the half-plates 42 and 44 have a reduced thickness and an upper edge 44b, 42b whose profile, as already explained, promotes the recovery of the tooling.
  • the drilling tool has a width H in the direction of axes of rotation X, X ', Y, Y' equal to 800 mm and a length L in the direction orthogonal to these axes of 2800 mm.
  • the surface opposing the ascent is less than 5% of the surface of the tooling. Indeed, during the ascent, the cutters are rotated and therefore do not oppose said lift. In the case of a cutting tool equipped with pairs of cutters whose axes have a width of 500 mm, this ratio is slightly less than 10%. In general, the ratio of the surfaces will preferably be less than 10%.
  • the thickness e of the support plate 40 is less than 15% of the width H of the tool in the direction of the axes of rotation X, X 'and Y, Y'. More preferably, this ratio is at most equal to 10%. The value of this report depends on the dimensions of the cutters. The larger these are, the more the ratio can be reduced. Indeed, the plate means 40 have a minimum thickness of 50 to 60 mm to give it sufficient strength and to allow the realization of the internal supply lines of the engines.
