Definitions

  • the present invention relates to the field of drilling in the ground, in particular with a view to manufacturing foundations, such as for example continuous screens made up of juxtaposed concrete wall elements.

  • This type of drilling machine is generally used for drilling in hard ground, for example in granite.
  • the displacement device makes it possible to exert a complementary thrust on the drilling tools, which aims to facilitate excavation.
  • the displacement device consisting of jacks, supports the weight of the drilling module when the machine is suspended, that is to say when it is not in contact with the ground to be drilled. This is particularly the case when the drilling machine is moved, for example to be brought in line with the zone to be drilled, or even when it is extracted from the excavation after the drilling operation.
  • the drilling module is particularly heavy since it includes the motorized cutting members, hydraulic circuits, as well as the pumping member. It is therefore understood that the jacks must support a very large weight when the drilling machine is suspended, which is liable to damage them.
