Definitions

  • the subject of the present invention is a method and a system. drilling wells in particular for the production of molded piles.
  • the dip tube is integral in translation and rotation of the auger 5, for example, by a system of dog clutch 12.
  • the jacks 3 are in extension of such so that the tool 14 is at the lower end of the core 6 auger.
  • the tube assembly can be reassembled using the crane auger plunger to completely fill the well with concrete or grout.
  • An object of the present invention is to provide a system for drilling which allows the realization of a well allowing the realization of a molded pile having improved qualities in particular by better quality control of the walls of the drilled well and in particular of the end lower of it.
  • a diameter of the hollow core of the auger relative to the external diameter of the suitable blade and on the other hand we control the speed of descent and of rotation of the auger in such a way that when it is used, we actually get at least partially a repression effect soil that provides better quality compaction of the well wall in its current part.
  • the system includes a platform 20 on which is mounted a guide mast 22 which is in vertical position in situation use. On this mast is mounted movable in vertical translation a carriage 24 which can be moved via cables 26 associated with an engine not shown.
  • the carriage 24 carries a drilling head 28 allowing the rotation of a vertical auger with a hollow core 30, this auger comprising a hollow core 32 and at least one blade 34 in helical shape extending substantially over the entire length of the core.
  • AT the inside of the hollow core 32 of the auger 30 is mounted free a tube rigid plunger 36 also hollow with which the lower end is fitted a tool 38 projecting from the lower end 32a of the core of the auger.
  • a movable plate 40 is connected to the drilling head 28 by vertical cylinders 42.
  • This plate 40 receives the upper end 36a of the dip tube 36 and supports a motor 44 for rotating the upper end of the dip tube.
  • the upper end 36a of the dip tube is connected to a flexible pipe 46 for supplying the concrete or grout tube by through a rotating joint.
  • the drilling head 28 comprises in particular a motor 48 for rotating the auger 30.
  • a rotary joint 50 ensures the connection through the plate 40 between the upper end of the dip tube 36 and the flexible pipe 46.
  • the drilling head 28 is also equipped with a detector 52 for measuring the actual auger rotation speed.
  • the cable 26 for vertical movement of the drilling head 28 or its motor drive is associated with a linear displacement sensor 60 which effectively measures the vertical displacement of the auger.
  • Figure 3 illustrates the relative position of the lower end 32a of the auger and the lower end 36a of the dip tube fitted of its tool 38.
  • the tube plunger 36 and the auger 32 are integral in rotation for example by a dog clutch system 62, concrete injection ports 64 of the tube diver being thus masked by the soul of the auger.
  • the jacks 42 are in the extended position so that the tool 38 carried by the dip tube is substantially at the level of the lower end 32a of the auger and that the injection holes 64 are masked by the auger.
  • the dip tube 38 supplied by the flexible pipe 46 by causing the auger and the tube to rise simultaneously plunger by raising the drilling head 28, the jacks 42 being held in their previous position. So we can perform the injection concrete or grout through the injection holes 64 of the dip tube in optimal conditions since the auger without rotation of the auger causes the excavated material to rise due to the drilling of the part current from well 66, which eliminates the risk of mixing of spoil with injected concrete or grout.
  • the dip tube is itself rotated during this operation.
  • the cylinders 42 are equipped with a pressure 54 of the control fluid. Measuring this pressure gives information on the nature of the soil at the lower end 68 of the well when the cylinders are controlled to cause the tube to descend plunger, the auger being itself immobilized.
  • the external diameter D1 is given the auger core and D2 the blade values such as the ratio of surfaces of the corresponding circles is between 25% and 75%. This choice allows to obtain, with the auger, a significant repression effect as soon as the digging speed of the auger is correct correlated to its rotation speed.
  • the end bottom of the hollow core of the auger is closed by the tool 38 mounted at the lower end of the dip tube.
