Definitions

  • the present invention relates to an apparatus and a method for measuring underground jet columns which are suitable for a drilling and nozzle linkage for producing a borehole such as a jet column in the region of the borehole.
  • the method of producing jet columns is a special civil engineering process in which a high-energy, high-pressure jet of water and / or binder leaks out of a rotating drilling and nozzle string, thereby destroying the surrounding soil with respect to its storage structure and mortaring it by adding binder.
  • a measuring device during processing, for example, on the drill and nozzle linkage.
  • a well-known drilling and nozzle linkage with a measuring device is in the European patent application EP 1 974 122 A1 disclosed.

With such a device is it is possible to flexibly and reliably monitor the quality of the jet columns during the operation of the drilling and nozzle boom.
  • the core idea of the present invention is to equip a probe element provided with a sensor with the properties preferred for the required application and to advantageously receive and guide it in the drill and nozzle linkage.
  • a measuring device for a drilling and nozzle linkage is provided.
  • the drilling and nozzle linkage is set up to create a borehole and a jet column in the area of the borehole. This means that with the drilling and nozzle linkage first a borehole is placed in a substrate / soil, and at a suitable depth the soil is softened (nozzle jet column).
  • the measuring device is, inter alia, adapted for measuring this jet jet column, in particular for measuring the diameter of the jet jet column, and the measuring device is integrated in the drilling and nozzle rod. Furthermore, the measuring device has a preferably provided with a sensor probe element, which from a retracted position to an extended position is movable, which probe element is deflected within the measuring device to a mounted on the measuring device input and Ausfahrgeophuse.
  • the probe element consists at least in sections of a shape memory alloy. It is preferably a metal alloy of nickel-titanium. A variant of this metal alloy is known under the name Nitinol.
  • such materials also have advantageous properties for use in civil engineering / special civil engineering.
  • the probe element for a deflection is flexible, but outside the measuring device, ie within the nozzle jet column, the external conditions stood and thus can lead the sensor for a measurement in the jet column.
  • the probe element is deflectable by an angle of substantially 90 °. This has the advantage that the probe element can be guided within the drilling and nozzle linkage, and can be discharged laterally out of the drilling and nozzle linkage.
  • this sensor could be a pressure and / or tilt sensor. Furthermore, with such a sensor, the diameter of the jet column can be determined, wherein the tilt sensor can ensure a valid measurement. It may therefore be particularly preferred for the sensor to have a plurality of combined individual sensors.
  • a measurement is carried out for detecting the jet column with the probe element and a further device. In particular, when the probe element is extended by monitoring the engine power, it can be ascertained when the probe element has reached the wall of the nozzle jet column: If the power consumption of the motor increases and at the same time an increase in the extended length of the motor is reached Detected probe element, then the probe element has reached the wall of the jet column.
  • the measures described for the detection and evaluation of the nozzle jet column can also be used in combination with each other.
  • the probe element is provided with the sensor, then this is in the operation of the measuring device according to the invention by the opening of the retraction and extension housing, which is attached to the measuring device, retracted and extended.
  • the sensor is designed such that, inter alia, dimensioned such that it seals the opening of the retraction and retraction in the retracted state.
  • a further preferred measuring device are provided within these roles, with which the probe element is deflected.
  • the roles provide a safe and less error-prone diversion, the probe element is not significantly changed externally in the promotion of the roles (ie, for example, is not deformed).
  • the probe element is sealed off from the drilling and nozzle linkage.
  • the probe element within the drilling and nozzle linkage is protected from dirt and contaminants, which can cause friction in the process.
  • a flushing channel can be provided in the retraction and extension housing, through which the probe element is flushed during retraction and extension with water or a suspension. This facilitates the sealing process and ensures that no contaminants get into the drilling and nozzle linkage.
  • a drive device is provided within this, with which the probe element can be driven.
  • the force application takes place here preferably in the region of the deflection of the probe element. This ensures a safe retraction and extension of the probe element in and out of the measuring device.
  • the feeler element is pre-curved prior to its deflection.
  • the pre-curvature can be provided here, for example, with the first roller in the area of the deflection.
  • the probe element is not deflected directly in the direction leading to the exit point of the probe element from the measuring device, but preferably against this direction. This facilitates the movement of the probe element, and it may be possible to realize a larger deflection radius within the measuring device after the probe element is further precessed to the wall of the measuring device. Also, this Vorkrümmung leads to a stabilization of the probe element.
