Definitions

  • the invention relates to a method for tilling the soil using construction equipment, which has at least one rotary drive unit for rotating a tilling tool that is inserted into the soil, according to the preamble of claim 1.
  • the invention relates to construction equipment for soil cultivation with at least one rotary drive unit for rotating a soil cultivation tool that is inserted into the soil, according to the preamble of claim 8.
  • Construction equipment for tillage is, for example, drilling equipment for drilling piles or trench wall cutters for producing trench walls in the ground.
  • a drilling tool is driven in rotation via a drilling drive and is usually introduced vertically into the ground by means of a feed unit.
  • a feed unit For efficient creation of a borehole, it is of essential importance that the rotational speed and a feed rate are adjusted to one another. For example, a different speed and feed rate is required for working on rock than for working on a layer of clay.
  • the drill driver must still have appropriate experience.
  • the right program must first be selected. Even when choosing the right program, for example for sandy soil, it can happen that in the course of the borehole to be drilled, different layers of the soil have to be penetrated, which can have different strengths and cohesiveness.
  • a tunnel boring machine which is designed to detect geological structures.
  • an output signal is generated by a signal generator, with a response signal being picked up by the geological structure by means of a sensor element.
  • an evaluation unit can be used to draw conclusions about the rock structure worked by the tunnel boring machine.
  • the invention is based on the object of specifying a method and construction equipment for tilling the soil, with which efficient tilling of the soil is made possible in a particularly reliable manner.
  • the object is achieved by a method having the features of claim 1 or by a construction device having the features of claim 8 .
  • Preferred embodiments of the invention are specified in the respective dependent claims.
  • the method according to the invention provides that at least one sound measuring device is provided, with which a sound is recorded when working the soil and forwarded as a measured sound value, and that a control and evaluation unit is provided, which uses the measured sound values to determine the type of soil to be worked.
  • a basic idea of the invention can be seen in the fact that when working the soil with a rotary drive unit, an essentially continuous generation of vibrations is brought about on the existing soil.
  • the soil tillage tool is driven at a substantially constant speed when tilling a soil layer.
  • noise is generated during soil processing.
  • This sound generated in this way can be recorded by means of at least one sound measuring device and forwarded to a control and evaluation unit as a measured sound value.
  • This control and evaluation unit is designed in such a way that the type of soil to be processed can be determined on the basis of the measured sound values recorded.
  • a characteristic sound image is produced which differs significantly from a sound image which is produced when working on a sand, clay or gravel layer, for example.
  • the sound is recorded as structure-borne noise, with the at least one sound measuring device being arranged on the soil working tool or in the vicinity of the soil working tool.
  • the sound could also be detected as a sound in the air or in a supporting liquid, for example in a borehole.
  • structure-borne noise which occurs on the soil working tool, in particular a drilling tool or a milling wheel, is particularly characteristic and can be detected with particularly good reliability.
  • appropriate sound measuring devices are attached directly to the metal parts of the soil working tool or in the vicinity of the soil working tool.
  • control and evaluation unit has a database in which certain sound values be stored for soil types.
  • the database can already be specified when a piece of construction equipment is delivered or it can be uploaded from a control center during operation or provided with new or supplemented values or maintained.
  • the device driver or the control and evaluation unit itself to store preferred data sets, i.e. sound measurement values or sound images for given operating variables for specific soil types, which are created for the respective construction site or for the respective construction equipment or have been identified.
  • the database can thus represent an expert system, with automatic improvement and modification of the stored data records being able to be provided on the basis of a preferably self-learning logic of the control and evaluation unit.
  • the method according to the invention consists in recording and storing the sound values over time and/or the depth of the ground. If, for example, several boreholes or slits are to be drilled at a construction site, which are usually close together or not too far apart, the stored operating variables, which are recorded and stored over time or the driving distance/soil depth with the determined sound values, can be used to create a Repeat program are used. In particular, a profile with the respective soil layers or soil characteristics can be created over a driving distance, ie a drilling depth or a slot depth, and a data set with preferred operating parameters for the construction equipment setting can be stored for this.
  • a soil profile is determined and stored by the evaluation and control unit based on the soil types determined during soil cultivation over the driving section.
  • a specific type of soil or soil layer such as loam, sand, gravel, rock, etc., can be assigned to a soil treatment value or soil characteristic value corresponding to data stored in the database.
  • These values and thus also a soil profile can be queried from a control center via the control and evaluation unit via a remote data connection that is preferably present.
  • construction equipment can not only be used to work the ground, but it can also be used as a a probing or analysis tool can be used to explore a soil profile.
  • the operating parameters preferred for the soil profile are determined via the drilling depth by the control and evaluation unit and stored as a data set in the database.
  • the database can already be specified when the construction equipment is delivered, or it can be uploaded from a control center during operation, or it can be provided and maintained with new or supplemented values.
  • the device driver or the control and evaluation unit itself to store preferred data sets, i.e. preferred input variables, possibly with output variables for certain recorded sound values or soil tillage values, which are used for a particular construction site or for the respective construction equipment have been created or determined.
  • the database can thus represent an expert system, with automatic improvement and modification of the stored data records being able to be provided on the basis of a preferably self-learning logic of the control and evaluation unit. This can also include an automatic improvement in the assignment of sound values or sound images to specific soil types.
  • the control and evaluation unit compares a current soil type with soil types stored in the database and that, depending on the comparison, a current operating parameter for operating the construction equipment is changed or a change is recommended to an equipment operator . If, for example, the control and evaluation unit recognizes by comparing the recorded values that a soil layer with changed strength and thus with a different soil tillage value or soil characteristic value is penetrated, the control and evaluation unit can adjust the operating parameters or input variables, such as speed or feed, change. If a data set with the same or similar soil tillage value or soil characteristic value is determined in the database, the control or evaluation unit can change the operating parameters according to the preferred data set found, or to the implement driver, for example display on a monitor.
  • the previous operating parameters can be replaced by more suitable operating parameters for the soil type detected.
  • an applied torque would be changed depending on the type of soil determined after evaluation of the database and replaced by a more suitable value which, for example, enables improved propulsion with less tool wear.
  • the control and evaluation unit determines and stores various data sets for a soil profile, which are preferably determined and differentiated with regard to rapid propulsion or a low-wear rotational speed. It is taken into account that there is no general optimal parameter setting for the operating parameters in soil cultivation. Rather, the preferred operating parameters depend on certain aspects or objectives in tillage. For example, particularly rapid soil cultivation, ie rapid propulsion, may be desirable, so that higher speeds or higher feed forces are provided in contrast to soil cultivation that is as wear-resistant or energy-saving as possible. Other objectives can also be provided, such as low-noise work with the lowest possible sound emission. For a determined tillage value, different data sets can therefore be stored for different objectives, which are categorized as efficient propulsion, particularly low-wear, energy-saving or low-noise emissions.
  • the method according to the invention can be used in the various tillage methods.
  • a particularly preferred variant of the method consists in drilling with a drilling tool or milling with a trench wall cutter as soil processing.
  • the drilling can be continuous drilling, for example with an endless auger, or discontinuous drilling, for example with a drill bucket or a simple auger drill.
  • the method according to the invention can also be used in double-head drilling, in which at least two rotary drive units are provided.
  • a first rotary drive unit can be provided for an internal drilling tool, while a further rotary drive unit is arranged for an external drill pipe.
  • rock drilling which can be carried out, for example, in anchor or HDI drilling in a roughly vertical wall or even at the ceiling area in a tunnel.
  • a trench cutter with at least one pair, preferably two pairs of rotatably driven cutting wheels is preferably provided for tilling the soil by means of milling.
  • the milling of a milled trench can be carried out in a one-phase, two-phase or a CSM® method, in which a soil mortar mixture is produced in situ in the milled trench by the milling machine.
  • One or more cutting wheel drives can be provided.
  • control and evaluation unit can also take into account the supply of binding agent, rinsing and/or support suspension.
  • binding agent rinsing and/or support suspension.
  • the construction device according to the invention for working the soil is characterized in that at least one sound measuring device is provided, with which a sound is recorded when working the soil and forwarded as a measured sound value, and that a control and evaluation unit is provided which is designed to use the measured sound values to determine the type of the soil to be worked.
  • a particularly preferred construction device is a drilling device in which a drilling tool is driven in rotation by means of the at least one rotary drive unit.
  • the drilling tool can be a drill bucket or an auger, which can preferably be moved vertically along a mast or a leader.
  • the drilling device can also have a drilling carriage that can be adjusted in multiple axes in space, for example as is used in anchor drilling or in HDI drilling.
  • all drills can be used, for example for Double-head drilling or drilling devices with a casing machine, in which casing pipes can be inserted into the ground.
  • this is a trench wall cutter in which cutting wheels are driven by means of the at least one rotary drive unit.
  • the trench wall cutter has one or more pairs of cutting wheels at the lower end of a cutting frame.
  • the milling frame can be suspended from a cable and guided in the milling slot via corresponding guide plates on the milling frame.
  • the trench cutter can also be guided and moved on a guide rod, which is particularly advantageous for CSM® milling, in which a soil mortar mixture is created in situ in the milled trench with the milled soil material and the supplied setting support liquid.
