Definitions
- the present invention relates to a device for drilling the auger type.
- Auger type drilling devices allow dig in the ground a generally cylindrical excavation of variable depth using the drilling tool, i.e. the auger, as it sinks into the ground.
- a problem that arises when carrying out such drilling is the management of the excavated soil as and when this drilling.
- Part of the excavated soil can be used to fill in recesses in the borehole wall. It can also be used to be partly mixed to a grout to carry out as the extraction of the tool out from drilling a solid inclusion in this excavation which then serves as "mold".
- An object of the present invention is to provide a device for auger type drilling which effectively achieves a large flexibility in the management of the fraction of the excavated soil according to the nature of the soil in which drilling is carried out, using the presence of casing.
- the casing is pushed into the borehole as it is dug by the auger by the displacement of the mounting head.
- the possibilities of translational displacement of the auger relative to the casing it is possible to cause the ejection of the soil excavated towards its wall or, on the contrary, causing it to rise to inside the casing.
- the auger is of the variable core type, that is to say that the auger core has a diameter which increases from the bottom to the high. This type of auger promotes lateral removal of spoil.
- the means for limiting the rotation of the casing include reliefs extending over the entire length of the face external of said casing and a holding part, integral with the means of guiding in vertical translation, provided with internal reliefs suitable for cooperate with the reliefs of said casing.
- a platform 10 is shown on which is mounted a vertical guide mast 12, the platform also supporting a number of devices such as 14 for allow the use of the drilling tool.
- the drilling device comprises also a carriage 16 which is subject to move in translation vertical along the guide mast 12.
- the guide mast could be replaced for example by vertical ropes supported by the end of a crane or the like, these cables used to guide the carriage 16 in vertical translation.
- the drilling tool consists of a rod rotation transmission 22 at the lower end 22a of which is fixed an auger 24 of known type.
- the upper end 22b of the rod 22 cooperates with the mounting head 18 to rotate the auger 24 via the rod 22.
- the cooperation between the upper end 22b of the rod and the mounting head 18 is such that this upper end of the rod can be moved in translation vertical to this head 18 while maintaining the drive in rotation.
- the drilling device also comprises a casing 30 which consists of a cylindrical piece of length 12 which surrounds the rod 22, the upper end 30a of which is integral with the mounting head 18 and the lower end 30b of which is open.
- Tubing 30 is introduced in drilling as it is excavated by the auger 24 under the effect of the descent of the mounting head 18.
- the control of the ascent and descent of the mounting head 18 along the mast 12 is produced for example by a cable system 32, pulleys 34 and winch 35, or by jacks.
- the lower part of the auger 24 which is referenced 24a has an external diameter D which is substantially equal to the external diameter D 1 of the casing 30.
- the upper part 24b of the auger 24 has a diameter less than the internal diameter of the casing 30 to allow the insertion of the upper part of the auger inside the lower end of the casing 30.
- the length I 1 of the auger 24 is much less than the length I 2 of the casing 30.
- the rod 22 is preferably equipped with discontinuous blades such than 36 which are arranged above the auger 24. These blades allow a partial recovery of the static charge due to the presence cuttings inside the casing, which limits the stress applied by these auger cuttings. Preferably, these blades have a pitch which goes in decreasing when approaching the auger.
- the auger 24 is rotated in the direction opposite to that which corresponds to drilling.
- the auger is of the variable diameter type.
- a first embodiment of such an auger is shown in FIG. 4 a .
- the core 90 has a diameter which increases from its tip 92 to its zone 94 of attachment to the rod 96.
- the external diameter of the auger that is to say of its blade 96, goes also increasing in this direction.
- the core 90 has a diameter which increases towards its tip 92.
- the outside diameter of its blade 96 ' is constant.
- the drilling device also includes means for resumption of the forces applied to the casing 30 due to the action of the auger and cuttings excavated on the casing.
- a lateral mechanical stop device 40 cooperating with a rib 42 extending at least over the part bottom of the outer face of the casing 30.
- the cooperation between the fixed mechanical stops 40 and the rib 42 makes it possible to immobilize in rotation of the casing or at least limit the possibilities of rotation.
- FIG. 1 shows the vertical guide mast 12, the carriage 14 on which is fixed a first mounting head 18 for an upper auger 50 which is fixed to the lower end of a hollow rod 52 whose upper part 52a cooperates with the mounting head 18 to rotate the upper auger 50.
- means for example by jacks 54 allow the rod 52 of the auger 50 to be displaced in vertical translation relative to the head mounting 18.
- the drilling device also comprises the casing 30 whose upper end 30a is integral with the mounting head 18 and whose lower end 30b is open.
- the external diameter d 1 of the upper auger 50 is less than the internal diameter of the casing 30.
- the drilling device comprises a second auger lower 56 which is integral with the lower end of a rod 58 whose upper part 58a cooperates with a second mounting head 60 connected to the carriage 14 or to the first mounting head 18.
- the rod 58 of the lower auger 56 is movable in vertical translation relative to the first mounting head 18.
- means by cylinders 62 are interposed between the lower mounting head 18 and the upper end 58a of the rod 58.
- the upper mounting head 60 is movable in translation relative to the carriage 14 by guide means symbolized at 64. In this case, it it is not necessary to provide the means by cylinders 62. It is possible also provide a single device to drive in translation at a time the mounting head 60 and the rod 52 of the upper auger 50.
- the lower auger 56 has an external diameter D 2 which is slightly greater than the external diameter of the casing 30.
- the lower auger 56 in normal operation, is used to drill the ground and to feed the upper auger 50, this making the cuttings penetrate inside the casing 30.
- the setting rotation of the upper auger 50 in a direction opposite to that of the lower auger 56, which of course promotes the ejection of cuttings towards the inner wall of the borehole.
- the end lower of the upper auger 50 must be arranged below the lower edge 30b of the casing.
- the augers 50 and 56 are lowered so that the upper end 50a of the upper auger 50 is disposed well below the lower edge 30b of the casing. We thus obtain easy flow of the cuttings contained in the casing. This flow can be favored by the rotation of the upper auger 50 and its discontinuous blades 36.
- the drilling tool can include also an injection tube 59 which is movably mounted by cylinders 61 in the rod 58 of the lower auger 56.
- this tube 61 generally called “dip tube” allows to inject at the bottom of the drilling, as the tool rises, a grout which, mixed or not to part of the excavated soil, is used to achieve an inclusion solid in this drilling.
- This tube can also be used to inject the part lower of the drilling a grout or a concrete, not mixed with the cuttings, for make a pile molded with grout or concrete.
- FIGS. 2b and 3 two examples of systems for immobilizing the casing in rotation or at least for limiting the rotation of the casing 30 under the effect of the forces resulting from the rotation of the drilling tool and cuttings present in the casing.
- the system comprises two arms 70 and 72 integral with the platform 10.
- the end free of each arm is equipped with a portion of slide 74 and 76.
- the casing 30, at least in its lower part, is provided, on its outer face, two vertical ribs 78 and 79 which extend at least on the lower part of the casing or which extend over the entire length thereof and which are engaged in the slides 74 and 76.
- arms 70 and 72 could be replaced by any other rigid connection system.
- this system could be secured to the lower end of the mast 12 instead of being secured to the platform 10.
- the free ends arms 70 and 72 are integral with a vertical sleeve 82 which surrounds the casing 30.
- the internal face of the sleeve is provided with grooves vertical or similar reliefs 82.
- the external face of the casing 30, at less in its lower part or over its entire length, is equipped with vertical grooves 84 or similar reliefs which cooperate with the grooves 82 of the sleeve 80.
