Definitions
- the invention relates to a measuring device for determining the orientation and the Course of a drill pipe.
- the sole is here by lined up by Injection bodies realized at a predetermined depth in the ground. To do this, a HDI rods sunk to the target depth of the sole to be created. There the Then the ground was cut open by high pressure injection, and the resulting one Cavity is pressed with a self-setting compound. The size of the The resulting compact depends on the range of the HDI beam in the ground from. Closed soles are created by overlapping arrangement of neighboring ones Compressed bodies produced, since imperfections in the sole only affect them Have ways effectively avoided. Deflections of the HDI boom during jacking in the ground and resulting deviations in the actual location of the HDI boom from its respective target position can now lead to neighboring grouting bodies do not overlap sufficiently, which results in defects can lead in the sole.
- an inclinometer probe is placed in the high pressure duct of the HDI linkage introduced and lowered in this. At fixed intervals measurements are then taken with the inclinometer probe after drilling.
- the object of the present invention is to provide a measuring device with who, without any noticeable disruption to the operational process, aligns and let the course of a drill pipe be determined with great accuracy.
- the above object is achieved by a measuring device with the features of Claim 1 solves.
- the measuring device specified there for determining the Alignment and course of a drilling rig includes several inclinometer sensors, which are distributed over the length of the drill pipe at defined positions of the Drill rods are arranged, an evaluation unit for the inclinometer sensors recorded measurement data and means for transmitting the measurement data to the evaluation unit.
- the orientation and the course of the drill pipe as a whole can then be simply using an evaluation unit be determined, the measurement data recorded simultaneously on all of the drill pipe arranged inclinometer sensors are supplied.
- the Use of the measuring device proposed according to the invention is extensive Automation of the measuring process, in which the alignment and the course a drill pipe with very little time and relatively high accuracy have it determined.
- the drilling process for measurements with the invention Measuring device can no longer be interrupted; the measurements can now be carried out with only minimal interruption of the operational process.
- the inclinometer sensors in a specially provided measuring channel of the drill pipe is arranged.
- a measuring channel offers a certain degree of mechanical protection for the Inclinometer sensors, on the other hand, it enables easy maintenance or one simple exchange of inclinometer sensors without impairing functionality of the drill pipe itself.
- the drill pipe rotates, and with it the drill pipe Inclinometer sensors.
- the orientation of the inclinometer sensors or the drill pipe should be measured values be known as precisely as possible.
- Devices are therefore additional means for recognizing the orientation of the drill pipe provided. This can be, for example Act on the marking on the drill pipe or arrange it at a suitable location Continuation.
- the inclinometer sensors are arranged in pairs are and form a uniaxial inclinometer pair.
- the evaluation unit of the invention In construction site operation, it proves to be advantageous to use the evaluation unit of the invention To operate the measuring device remote from the inclinometer sensors, d. H. separated from the drill pipe on a protected and easily accessible To place. In this case it is advisable to use the inclinometer sensors to transmit the measured data wirelessly to the evaluation unit. For example done by radio or infrared.
- the course of the drill pipe is inventively with the help the evaluation unit based on the measurement data recorded by the inclinometer sensors certainly. Since the execution of a construction project is usually logged, it is advantageous, in addition to the evaluation unit, also means for storing the measurement data and / or to provide the measurement results in the form of the evaluated measurement data. In connection with monitoring a drilling operation, it is also from Advantage, if also means for tabular and / or graphic visualization of the Measurement results are provided.
- the measuring device according to the invention described very generally above proves to be particularly useful for determining the alignment and course of a Jet boom, such as of an HDI boom, as advantageous.
- This kind of Drill pipe is used in a wide variety of construction projects, as in the Nozzle jet method grouting body for various purposes in the subsoil let create.
- the single figure shows a drill 1, which is on the floor surface 2 next to one Hole 3 is arranged.
- an HDI linkage 4 is attached, which is already is sunk to a large extent in building site 5.
- the only figure illustrates that the alignment of the HDI linkage 4 in the ground 5 from the vertical deviates, although the HDI linkage 4 is driven vertically into the subsoil 5 has been. This deviation could, for example, be due to obstacles in the building site 5 his.
- the four inclinometer probes each with a pair of inclinometer sensors comprises, which is distributed over the length of the HDI linkage 4, at defined positions of the HDI linkage 4 are arranged.
- the inclinometer sensors 6 arranged in a specially designed measuring channel or measuring tube, which is integrated in the HDI linkage 4.
- the inclinometer sensors 6 are arranged in fixed, here equal intervals in the measuring tube. Every inclinometer probe includes a pair of uniaxial inclinometer sensors that measure the tangent slope in a discrete measuring point, namely at the location of the inclinometer sensor pair.
- the evaluation of the tangent slopes recorded as measurement data in the measurement points positions of the inclinometer sensors 6 are carried out with the aid of an evaluation unit, which is operated remotely by the inclinometer sensors 6 and itself in the present case, for example, could be located in the drilling device 1.
- an evaluation unit which is operated remotely by the inclinometer sensors 6 and itself in the present case, for example, could be located in the drilling device 1.
- There could be additional also means for storing the measurement data and / or measurement results and means for visualizing the measurement results can be arranged so that the operating personnel not only monitor and control the drilling process from the drilling rig could but could also log.
- the evaluation unit can a laptop, a handheld PC, an IPC system or the like.
- the history of the HDI linkage 4 is obtained by approximating the data recorded as measurement data Tangent slopes taking into account the orientation of the HDI boom determined. From this, the deviation of the actual drilling profile from determine the desired course of the HDI linkage 4.
- the evaluation unit is set down by the inclinometer sensors 6 operated.
- the measurement data of the inclinometer sensors 6 are transmitted via a Infrared interface below the flushing head of the HDI boom 4 to the evaluation unit transfer.
