Definitions

  • the subject of the present invention is a transmission method information by a special drill string which is used to manufacture columns more resistant than the ground in place, this drill string allowing, this train of rods allowing the transmission of said information between its upper end near the ground surface and its lower end carrying the drilling tools.
  • the technique of soil consolidation by destructuring ground by a jet of liquid at very high pressure most often called “jet grouting” consists in making columns of soil concrete (mixing in place of land with a binder provided by the jet fluid) from a drilling using a drill string in which the fluid is sent to high pressure to make the column.
  • jet grouting uses two fluids.
  • She is made of conventional way using a double column drill string, i.e. having an internal pipe for driving the two fluids at the bottom of the borehole.
  • the central pipe conveys the jet liquid, usually a mixture of water and cement, and in the annular space between the external wall of the tube and the internal pipe circulates the compressed air.
  • a first object of the invention is to provide a support for transmission of information using a drill string for the technique "double jet” which is simpler to use and can be used with standard “double jet” rods.
  • Another object of the invention is to provide a drill string for the implementation of the "double jet” technique which allows improved information transmission.
  • the current loop is formed by the conductive elements formed by the external wall of the rods and by the internal pipe of these same rods which are separated by the insulating gas filling the annular space between these two tubes coaxial.
  • This transmission of information does not require no modification of standard rods. It simply requires putting inductive coupling coils in the drill pipe lower and in the upper drill pipe.
  • the lower coil in this embodiment, plays the role of transmitter and the upper coil plays the role of receiver enabling information to be transmitted to processing and operating facilities located on the ground surface.
  • the information applied to the first coil i.e. at the lower coil
  • the information applied to the first coil are the ones that are delivered by the sensors mounted in the lower part of the train rods and that this same information, possibly transformed as to their shape, are collected by the upper coil and transmitted to treatment units arranged on the ground surface.
  • FIG 1 there is shown in a simplified manner a drilling machine by "double jet”.
  • This figure shows a platform 10 preferably mounted on tracks 12 on which is articulated at its lower end 14a a vertical guide mast 14.
  • the mast 14 is used for guiding in vertical translation of a carriage 16 which carries itself a drilling head 18 or rotation head.
  • the drilling head 18 is used, on the one hand, for the rotation of the drill string 20 constituted by the elementary rods 20a and for the downward movement of the drill string under the effect of the descent of the carriage 16.
  • a l 'upper end of the drill string there is in particular a rotary joint 22 which allows the supply of pressurized air and jet liquid 24 and 26.
  • the lower rod 20 i is equipped with the jet tool 28 and d '' a mechanical drilling tool 30.
  • each rod 20a is constituted by an external tube 34 and by an internal coaxial pipe 36.
  • the external wall 34 and the internal pipe 36 define between them an annular space 38 which is used for conveying the pressurized air to the jet module 28.
  • the internal coaxial pipe 38 is used for conveying the pressurized liquid also to the jet module.
  • a first coil 40 of electromagnetic coupling which coil is mounted in the annular space 38 filled with pressurized air.
  • This coil 40 surrounds the internal pipe 36.
  • the external wall 34 of the rod has a portion of larger diameter 42.
  • the coil 40 is connected by electrical conductors such as 44 to the sensors of the module 32.
  • a second coil 46 is mounted which surrounds the internal pipe 36 and which is arranged in the annular space 38. This second coil 46 is connected to electrical conductors 48 by means of the rotary joint 22.
  • the outer wall of the rods 20 and the internal pipe 36 of these same rods are made of a metal or a electrically conductive alloy. It is understood that the internal pipe 36 and the outer wall 34 electrically connected at their ends superior and inferior by any suitable means constitute a conductive loop well suited for transmission according to the mode of current loop.
  • the coils 40 and 46 are mounted on one of the conducting elements of this current loop constituted by the internal pipe 36 and external wall 34. If so, we apply a signal non-continuous electric to the lower coil 40, an induced current is created in the current loop defined above and is therefore collected by the upper coil 46. We therefore obtain, on the coil 46 and the conductors 48 associated with it, an electrical signal representative of the electrical signal that has been applied to the lower coil 40. If the signal applied to the coil 40 is representative of measurements made by the sensors arranged in the measurement compartment 32, it is understood that electrical signals representative of these measurements, these electrical signals being able to be processed in real time at the surface.
  • a verticality sensor 50 used to control the verticality of the drilling tool and a sensor 52 making it possible to measure the thickness of the column produced in the jet phase. He could of course there are other sensors arranged in this compartment.
  • the measurement sensors 50, 52 are connected to an interface component 56 which converts the electrical signals delivered by the sensors and corresponding to the measurements made in digital measurements then in an alternative signal representative of the digital information. It is by example of a generator of fixed frequency and fixed amplitude which delivers an alternating signal in the periods when the digital signal has the value binary 1 and which does not deliver any alternative signal in the case where the signal numeric has the binary value 0. This is shown in Figure 4.
  • the frequency signals produced by the interface circuit 56 are applied to the lower inductive coupling coil 40 by the conductors 44.
  • the inductive coupling coils 40 and 46 consist of a torus-shaped magnetic core surrounding the internal pipe 36, core on which an electrical conductor is wound to constitute a conventional type electromagnetic coil.
  • the upper receiving coil 46 which is connected via the rotary joint 22 to the electrical output conductor 48.
  • the coil 46 is preferably also produced using a magnetic core in the form of a torus 58 and an electrical conductor wound on this core 60.
  • FIG 3 there is also shown schematically the arrival of the pressurized liquid 62, for example cement in suspension in water to supply the internal pipe 36 and the supply of compressed air 64 to supply the annular space 38.
  • the jet compartment 28 there is also shown schematically an injection nozzle 66 connected to the axial pipe 36 and a annular nozzle 68 connected to the annular space 38 in which circulates pressurized air.
  • the processing assembly there is a lower emitting coil 40 connected to the sensors and an upper coil 46 connected to the processing assembly.
  • Information therefore flows from the bottom of the drill string to the ground surface.
  • the two coils will preferably consist of a single magnetic core on which a transmitter winding and a receiver winding will be wound.
  • each coil can be associated with a switching device which allows it to be connected either to a receiving circuit, either to a transmitter circuit.
  • the two electromagnetic coils associated with the loop current defined above also allow transmission of electrical energy from the surface to the measurement compartment 32 to recharge the battery or accumulator 54. This transfer of energy is carried out in periods when no information is to be transmitted.
  • the technique of "triple jet” is used.
  • a liquid jet and a pressurized air jet are used to deconstruct the ground while the third jet is used to supply the grout for the realization of the column.
  • the rods then have two pipes internal coaxial.
  • the coupling coils inductive will still be arranged in the annular space in which pressurized air flows.
