Definitions

• the invention relates to a method for tillage with a construction device, which has at least one rotary drive unit for rotationally driving a tillage tool and at least one feed unit, with which the tillage tool is introduced into the ground, according to the preamble of claim 1.
• the invention further relates to an apparatus for cultivating soil with a rotary drive unit for rotationally driving a cultivating tool and a feed unit, with which the cultivating tool can be introduced into the ground in a propulsion direction, according to the preamble of claim 12.
• a drilling tool is driven in rotation by a drilling drive and is usually placed vertically in a ground by means of a feed unit.
• a feed unit For an efficient creation of a borehole, it is of essential importance that the rotational speed and a feed rate are adjusted to one another.
• the speed and feed rate are manually set by a drill driver.
• the correct setting thus depends heavily on the experience of the drill driver, especially since the setting also depends on the type of soil.
• drills are provided with an electronic control in which preselected programs are provided, which are provided by a drill driver can be selected depending on the soil type present.
• programs for example, a speed of the drilling tool and a feed rate for a particular type of soil can be specified.
• the controller will then adjust and control torque and feed force on the drill based on these setpoints.
• the resulting actual values can be measured and compared with the desired values, so that a conventional control is given.
• the invention has for its object to provide a method and a construction equipment for tillage, with which an efficient tillage is possible in a particularly reliable manner.
• the method according to the invention is characterized in that a control and evaluation unit is provided, with which at least one input variable of the rotary drive unit and / or the feed unit is detected and stored during soil cultivation, and at least one resulting output variable is detected and stored on the soil cultivation tool and the at least An input quantity is related to the resulting output, whereby a soil working value is determined and stored.
• a basic idea of the invention is that, by means of a control and evaluation unit, at least one input variable and at least one output variable during soil cultivation are recorded continuously or at regular intervals and set in relation to each other. If, for example, a specific torque is applied to the rotary drive unit as the input variable, then the rotational speed on the soil working tool, for example a drilling tool or a cutting wheel, which is influenced by the soil, allows conclusions about the type of soil, for example whether it is firm or loose.
• the control and evaluation unit can thus make a statement about the soil workability by comparing the input variable and the resulting output variable, whereby a soil cultivation value is determined. This soil working value can be displayed to a device driver or taken directly into the control for the further operation of the drive units and the feed units.
• a preferred development of the method according to the invention is that the at least one input variable and the at least one output variable are detected and stored over the time and / or the tunneling section. If, for example, several boreholes or slits are to be created at a construction site, which are usually close to each other or not too far away, the stored input and output variables which have been recorded and stored over the time or the tunneling section in one operation can be used to create a Repeat program can be used.
• a profile with the respective soil cultivation values can be created by means of a tunneling section, that is to say a drilling depth or a slot depth, and a respective data set with preferred operating parameters for the input variables can be assigned to each of these.
• an input torque of the rotary drive unit, a feed force of the feed unit and / or a pressure or a volume in a hydraulic system for driving the rotary drive unit and / or the feed unit is selected.
• the rotary drive unit may be a drill drive or a cutting wheel drive.
• the torque can be detected directly.
• the torque and thus the tapped power can be detected indirectly via parameters in the hydraulic system, in particular a pressure or a volume flow in the hydraulic system.
• a feed unit which can be done via a winch or adjusting cylinder, which can also be operated with a hydraulic drive system.
• the feed unit may be about a trench wall cutter or the weight of the trench wall cutter, which is suspended on a winch rope and reduces the ballast by a corresponding counterforce of the winds.
• the ballast can thus be determined by means of corresponding force sensors or computationally via a winch torque, taking into account the weight of the trench wall cutter, and included in the determination of the tillage value.
• the output variables are in an operative relationship with an assigned input variable.
• a speed and / or a feed rate of the tillage tool be selected as the output variable.
• a torque on a rotary drive unit is related to the speed of a tilling tool, such as a drilling tool or a cutting wheel.
• a feed force or load is associated with a resulting feed rate.
• a given feed force results in a higher feed rate compared to a firmer ground.
• the feed rate may also be referred to as the penetration or advance rate into the ground.
• a speed may also be predetermined by the control unit as an input variable, in which case a resulting torque or a power tap on the rotary drive unit is detected as the resulting output variable.
• a further preferred embodiment of the invention consists in that the control and evaluation unit has a database in which preferred input variables for specific tillage values are stored.
• the database can already be specified when a construction equipment is delivered, or it can be installed by a central office during operation or provided with new or supplemented values and maintained.
• the device driver or the control and evaluation unit itself to store preferred data sets, that is to say preferred input variables with output variables for specific soil cultivation values, which are created for a respective construction site or for the respective device or determined.
• the database can thus represent an expert system, whereby an automatic improvement and modification of the stored data sets can be provided on the basis of a preferably self-learning logic of the control and evaluation unit.
• the control and evaluation unit compares a current soil cultivation value with soil cultivation values stored in the database and that a current input variable is changed or a change is recommended to a drill driver depending on the comparison. If, for example, the control and evaluation unit recognizes by comparing the input variable, for example the torque, with a resulting output variable, ie an adjusting rotational speed of the drilling tool or the cutting wheel, that a soil layer with a changed strength and thus with a different soil working value is discussed, the Control and evaluation according to the currently determined soil working value change the input variables.
• control or evaluation unit can determine the input quantity in accordance with the determined Change record, or the device operator, for example, display on a monitor.
• the previous input variable can be replaced by the more suitable input for the tillage value. In this case, therefore, an applied torque would be changed depending on the determined tillage value after evaluation of the database.
• a soil profile is determined and stored by the evaluation and control unit on the basis of the soil cultivation values determined during tillage.
• data stored in the database can be assigned to a soil cultivation value of a specific soil type, such as loam, sand, gravel, rocks, etc.
• these values and thus also a soil profile can be queried via the control and evaluation unit from a control center.
• a construction equipment can not only be used for working the soil, but it can also be used as a probing or analysis tool for exploring a soil profile.
• preferred input variables are determined by the control and evaluation unit for the soil profile via the tunneling section and stored as a data record in the database.
• a pattern data set for a hole can be created at a construction site, wherein for example up to a first drilling depth a first torque and a first feed force, then up to a second depth, a second torque with a second feed force and so on are stored.
• Such a record for a hole or a slot can then be retrieved for another hole at the same site. It can be assumed that at a construction site, a soil profile does not change or hardly changes, especially if holes or slots are created close to each other. This is often the case when creating pile walls or diaphragm walls. Based on the data of the pattern hole or the pattern slot, the further holes or slots can also be created effectively by less experienced device operators.
• the control and evaluation unit determines and stores various data sets for a soil profile, which are preferably determined and distinguished with regard to rapid propulsion or a wear-conserving rotational speed. It is taken into account that there is no general optimal parameter setting for the input variables during tillage. Rather, the preferred inputs depend on certain aspects or objectives in tillage. It may be about a particularly fast tillage, so a quick advance, be desired, so that higher speeds or higher feed forces are to be provided in contrast to a low-wear or energy-saving tillage as possible. Other objectives may also be specified, such as sound-saving work. For a determined tillage value, therefore, different data sets for different objectives can be stored, which are categorized under efficient propulsion, for example, with particularly low wear, energy-saving or low-noise emissions.
• the method according to the invention can be used in the various soil cultivation variants.
• a particularly preferred variant of the method is that drilling is carried out as a soil treatment with a drilling tool.
• the drilling may be a continuous drilling, such as with an endless screw, or a discontinuous drilling, such as a drilling bucket or a simple auger.
• 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 may be provided for an internal drilling tool, while a further rotary drive unit is arranged for an external drill pipe.
• rock drilling is also included, which can be performed in an approximately vertical wall or even at the ceiling area in a tunnel, for example in the case of anchor or HDI drilling.
• a further preferred variant of the method can be seen in that as a tillage a milling with a trench cutter is performed.

• the milling of a Frässchlitzes can in one A one-phase, two-phase or a CSM ® -Verfahren be performed, in which in-situ in the Frässchlitz by the cutter a Bodenmörtelmischung is produced. It can be provided one or more Fräsradantriebe.
• a supply of binder, rinsing and / or supporting suspension may also be taken into account in the control and evaluation unit according to the invention.
