Definitions

  • the probe element is equipped with a sensor, in particular a pressure sensor and / or an inclinometer.
  • a sensor in particular a pressure sensor and / or an inclinometer.
  • the sensor or sensors can be provided, for example, in the space defined by the spring.
  • the pressure sensor is arranged, for example, on a wall of the borehole contacting end of the probe element. As a result, the borehole wall is reliably recognizable even with a relatively loose soil.
  • the inclinometer the orientation of the sensing arm can be detected or controlled during a measuring process and thus the target position of the probe element can be verified.
  • the measuring device comprises actuating means for the probe element.
  • the probe element is extended until, for example, the resistance due to the contact of the probe element with the borehole wall opposes the movement and / or a pressure sensor signals an end of a movement.
  • the actuating means a particularly simple movement of the probe element is possible.
  • the actuating means can be designed in the context of the present invention in various ways. In this case, an embodiment has proven to be advantageous in which the actuating means have a provided within the drilling and nozzle rod actuating piston. In an alternative embodiment, the actuating means on an electric drive provided within the drilling and nozzle linkage, which preferably drives drive means, in particular at least one drive roller, wherein a transmission is particularly preferably provided between the drive means and the electric drive.
  • the pressure fluid channel is connected via a switching means alternately to a pneumatic and a hydraulic supply.
  • a suitable supply i. a suitable working fluid such as compressed air or hydraulic fluid can be selected.
  • the method of making and measuring a jet column in a subsurface comprises the steps of: creating a wellbore in a subsurface using the drilling and nozzle string, creating a jet column in the area of the wellbore using the drilling and nozzle string, measuring the jet column using the (mechanical) measuring device, without the drilling and nozzle rod has been previously pulled out of the hole.
  • the (mechanical) measuring device By measuring without pulling out of the drill and nozzle linkage a fast and reliable quality control is possible.
  • Evaluation of the measurement data takes place either directly by transferring the data to the surface (eg also by radio) and / or indirectly by storing the data and reading out the data after the drill and nozzle linkage has been pulled out of the borehole is.
  • FIG. 3 shows an enlargement of the region B according to FIG. 1;
  • FIG. 4A shows an enlargement of the representation of a region C according to FIG. 1;
  • FIG. 4B shows a sectional view along A-A according to FIG. 4A;
  • Figure 7 is an enlarged view of the region E of Figure 1;
  • Figure 8 is an illustration of an inventive
  • Figure 1 shows schematically a cross section through an inventive drill and nozzle linkage 1 according to a first embodiment.
  • the drilling and nozzle linkage comprises a drill collar 12 shown in detail in FIG. 2, an area shown in detail in FIG. 3 with a nozzle for applying a jet of jet air, an area shown in detail in FIGS. 4A, 4B and 5 for the measuring device 4.
  • FIG. 4B shows a section through the drill pipe along the line AA according to FIG. 4A.
  • a cross-sectional area 46 is provided in which, for example, a power supply, an inclinometer, a programmable controller for the measuring device or the like can be integrated.
  • the power supply is preferably by battery elements.
  • a nozzle jet column is generated in the region of the borehole in a working step IV.
  • steps V and VI the diameter of the generated jet column is measured at different heights.
  • the scanning element 40 shown in the preceding figures is moved in the not yet cured jet column.
  • the probe element 40 is here advantageously designed such that it is kept substantially horizontal due to the buoyancy, the inherent rigidity and the dead weight.
  • step VII the drill and nozzle linkage is pulled out. This data, which were stored during the drilling and surveying in steps V and VI, read out. Based on these data, suitable statements can be made about the nature of the soil and the dependent condition of a generated jet column. These can be advantageously used for a project following step 8.
  • the present embodiment allows in a particularly simple manner, that the outlet opening 44 is in communication with the pressure fluid channel 30, so that the outlet opening 44 flushes continuously with pressurized fluid is, whereby the ingress of contaminants along the probe element 40 can be largely avoided.
  • counting elements may be provided which detect the revolutions of the drive rollers 41 '. These may be, for example, so-called incremental encoders.
  • the use of an electric drive makes it possible to dispense with the provision of a pressure sensor and inclination sensor in the feeler element 40, since it can be concluded during the advancement of the feeler element from an increase in the current absorbed by the electric drive that the feeler element reaches the wall Has.
