Definitions

  • the invention relates to a drilling rig with subsoil detection, which is designed to analyze the subsoil during an earth bore.
  • Drilling rigs for ground drilling are known in various designs from the prior art.
  • a drill head is attached to an extendable rod and rotated into the ground. Drilling takes place via a drive that sets the drill rods in rotating motion.
  • Such a drilling rig is usually of compact design, so that it can be made transportable.
  • Erdlochbohrmaschinen can be designed in particular for vertical and horizontal drilling.
  • Drilling emulsions make it possible to soften the area of the drill channel in front of the drill head and thus improve the cutting effect. Furthermore, the removed earth material is flushed out and for this purpose an annular gap between the drill rod and the drill channel is kept open, which at the same time reduces the skin friction between the drill rod and the drill channel wall, with the drilling emulsion also acting as a lubricant.
  • Drilling emulsions are in particular in the form of a dispersion of water and bentonite and can also contain additives, with adjustment to the material properties of the drill bed being necessary here.
  • An advantageous solution for the material composition-adaptive provision of a drilling emulsion is, for example, by DE 10 2017 002 336 A1 known.
  • the mechanical operating parameters such as speed, penetration depth, penetration depth per revolution, etc. can usually be set via the machine according to the prior art. Furthermore, with an existing device In addition, the composition of the drilling emulsion can be prepared and supplied according to requirements.
  • the operating parameters it is usual here for the operating parameters to be set manually by the system operator. It is particularly disadvantageous here that the decision-making basis for the setting of the operating parameters is based on the assessment and the experience required for this by the plant operator or on subsoil analyzes carried out beforehand. The disadvantage here is that subsoil analyzes are time-consuming and costly and generally only provide information on certain reference sections of the future drill channel.
  • the quality of a borehole depends on the experience of the plant operator and thus on subjective factors.
  • the quality of a well including the time required, energy required, the consumption of drilling emulsion and in particular the stress and wear on the drilling rig, can thus be disadvantageously suboptimal and fluctuate greatly.
  • the object of the invention is to provide a drilling rig with which ground drilling can be carried out efficiently and with high quality and the service life of the rig or of components of the rig can be increased.
  • the drilling rig according to the invention is preferably designed as a horizontal drilling rig and has a mechanical drilling unit, a sensor unit and a subsoil detection unit as basic components.
  • the drilling rig is preferably designed to be compact so that it is easily transportable.
  • the system can, for example, be set up directly on various chassis or housed in standardized freight containers.
  • the drilling mechanism unit has a drive assembly, a drilling assembly and a drilling emulsion unit.
  • the mechanical drilling unit includes, in particular, the drill head and the drill rods and is used directly for the mechanical removal of the soil in the form of a borehole. To do this, a drill head with an extendable rod is driven into the ground.
  • the area of the subsoil into which the borehole is to be drilled is referred to below as the subsoil.
  • a pilot bore is preferably first introduced in a feed movement.
  • the pilot bore is guided to an outlet opening at the target point.
  • the drill head is now accessible and is now exchanged for a clearing drill head, which is designed for removing subsoil in a clearing bore and usually has a larger diameter than the drill head for the pilot bore.
  • the clearing bore is then carried out by a retraction movement with a simultaneous rotating cutting movement of the clearing drill head and the drill channel is thus widened.
  • the rotary movement required for this and the superimposed feed movement, as well as the retraction movement in the case of a clearing bore, are generated by the drive assembly.
  • This is also known as such from the prior art and preferably has at least one motor, one gear and a correspondingly solid frame.
  • the drilling rig according to the invention is characterized in particular by the sensor unit and the subsoil detection unit.
  • the sensor unit according to the invention is designed to record a number of parameters of a drilling process.
  • the sensor unit has a plurality of sensors. The parameters are recorded using these sensors.
  • sensors can be arranged as additional structural units on the relevant elements of the mechanical drilling unit. However, it is also possible that the sensors are already present as integrated structural units of the mechanical drilling unit and the mechanical drilling unit provides an interface via which the data from the sensors can be output and then further processed.
  • the sensors thus determine the parameters that are important for the process. These are in particular mechanical parameters.
  • the shearing or pulling force provides information about the axial force applied to the drill head in relation to the ground for drilling advance or about axial skin friction when pulling out the drill rods and thus enables conclusions to be drawn about the properties of the subsoil material such as in particular the soil density or hardness. This also applies in a corresponding manner to the torque in connection with the speed. Further of the sensors correspondingly record further characteristic values.
  • the amount of drilling emulsion and the drilling emulsion pressure applied can also be related to one another and to parameters and thus allow more precise conclusions to be drawn about the properties of the subsoil material.
  • the properties of the subsoil material are also referred to below as subsoil properties or subsoil properties.
  • the important parameters for each drilling process can be determined, with the strength and rock mechanics being different depending on the type of rock or soil.
  • some of the parameters can also be specified as setting values by the plant operator during the operational management of the drilling plant.
  • the parameters are partly inevitably related to one another, so that, for example, at a certain speed and a certain rate of advance depending on the subsoil properties - at the same time depending on the amount of drilling emulsion and other factors - a certain torque results.
  • the sensor unit is designed to provide the detected parameters in a transferrable manner, so that they are available for further processing by the subsoil detection unit.
  • the subsoil detection unit according to the invention is connected to the sensor unit and receives the data from the sensors in this way.
  • the subsoil detection unit has, in particular, an evaluation unit.
  • the evaluation unit is preferably a computer.
  • the evaluation unit according to the invention is designed to evaluate the detected parameters and to provide an evaluation result.
  • both the absolute values of the individual parameters referred to below as absolute values, and their relative ratios as relative values to one another are used.
  • the more parameters are recorded and evaluated, the more different relationships and thus different relative values can be between the individual parameters are formed.
  • an evaluation result is provided, for example, as a data set that has relative values and preferably both absolute values and relative values.
  • relative values are preferably set in relation to one another, so that derived relative values can also be formed and made available as part of the evaluation result.
  • further derived relative values can be set in further relationships to parameter values, so that derived relative values of the second and higher orders can also be formed.
  • Absolute values, relative values and derived relative values of all orders are collectively referred to as the parameter values
  • the evaluation unit is also designed to assign the evaluation result to a subsoil type that can be stored.
  • the evaluation unit preferably has a storable database.
  • Multi-dimensional value corridors for characteristic values such as absolute values, relative values and derived relative values can be stored here for different subsoil types.
  • a comparison module is used to compare the evaluation result and the range of values, with the relevant subsoil type being assigned to the evaluation result if there is a match.
  • the evaluation unit also has a data output unit which is designed to output the allocated subsoil type as a determined subsoil type.
  • a data output unit is any device that is designed to make a determined subsoil type recognizable for a plant operator or for further technical processing.
  • the data output unit can therefore be, for example, a display, a monitor, an interface or a memory, for example for documentation of a drilled hole.
  • the present invention is based on the fact that, surprisingly, it was found that a significant improvement in the service life of a drilling rig and in particular "the drilling tools such as the drill heads and the drill rods can be achieved with little effort by means of reliable subsoil detection. It was also found that, in particular, the formation of relative values and derived relative values enables a high assignment reliability.
  • Operating processes of this kind are understood to mean, in particular, the operational management of the drilling rig with the aim of achieving certain operating states, as well as tamper-proof documentation of a drilling operation.
  • the rig operator can be provided with a model operating scheme that serves as a guide and significantly reduces the likelihood of sub-optimal operation.
  • the technical requirements for the personnel are reduced so that even less experienced plant operators can operate a drilling rig.
  • the effectiveness of the drilling can be increased, for example by making better use of the subsoil type-specific possible advance speeds, reducing the energy consumption to the required level and the wear and tear of plant parts and consumption of drilling emulsion, for example, can be reduced.
  • Another important advantage is the objectivity of the assessment of the subsoil based on measurement data. Both the measurement data and the output subsoil types can be documented in a tamper-proof manner and thus a This can be the basis, for example, for a cost calculation as well as for a wear assessment of the drilling rig.
  • the drilling rig is characterized in that the evaluation unit is designed to assign a drilling head position to the type of subsoil determined.
  • the exact geoposition data of the subsoil type can be assigned and documented. Furthermore, there is the advantage that information about the drill rods that are subject to skin friction is also available, so that the torque component that is attributable to the drill head and the torque component that is attributable to the skin friction can be better expressed in the evaluation result, thus further increasing the assignment reliability can.
  • the drilling rig is characterized in that the sensor system has a GPS module with which geoposition data can be provided and the evaluation unit is designed to evaluate the geoposition data.
  • a subsoil cadastre can be created with the help of the geoposition data.
  • a drilling area can be stored in the database with its locally recognized subsoil conditions. This means that the data on the condition of the subsoil can also be read from the database using the geoposition for any later applications such as further drilling or for construction work.
  • data that is already available on the condition of the subsoil can be assigned to an evaluation result and used for a Subsoil type recognition or in addition to a recognized subsoil type for a plausibility check.
  • the drilling rig is characterized in that the evaluation unit has a control module which is designed to assign a determined subsoil type to an operating scheme that can be stored. Furthermore, the control module is designed to call up the assigned operating scheme as an established operating scheme and to use the established operating scheme to generate control commands that are transmitted to the drilling mechanism.
  • the control unit then controls and regulates the drilling mechanism, preferably similar to a computer-programmable control based on a microprocessor unit.
  • the system is designed to be self-learning, based on a neural network that adds artificial intelligence to the control.
