Definitions
- the invention relates to a soil cultivation device for creating a substantially vertically running hole in the soil, which is provided with a supporting liquid, with a base body, a connecting device which is arranged on an upper end region of the base body, and a soil removal device and/or a soil displacement device which is arranged at a lower end area of the base body, according to the preamble of claim 1.
- the invention relates to a method for creating a substantially vertical hole in the ground with such a soil treatment device according to claim 13.
- a soil working tool such as a drill bucket.
- the well may be completed as a cased or uncased well.
- a support fluid is to be provided, which supports the well against collapsing.
- discontinuous drilling When using a drill bucket, discontinuous drilling must be carried out.
- the drilling bucket fills with removed soil material until it is complete or at least largely filled. Then the drill bucket is to be pulled out of the liquid-filled hole, with a drill pivoting above the surface to an emptying position at which the drill bucket can be emptied. The drilling bucket is then swung back and driven back into the borehole in order to carry out another drilling step.
- a drilling bucket is not sufficiently filled during a drilling step, additional drilling steps are necessary. This means additional expenditure of time and money. If, on the other hand, the drilling bucket is overfilled, the soil material in the drilling bucket can become so strong compacted so that it does not fall out of the drill bucket by itself when the bottom is emptied. Additional manual operations for emptying and cleaning the drilling bucket are then necessary. This also means additional expenditure of time and money.
- the WO 99/00575 A2 shows a continuous drilling method in which several sensors are arranged on the drill string, for example to be able to measure the ambient pressure at the respective position on the drill string. During its translational movement in the borehole, the drill string is continuously rotated. The sensors collect data only during drilling and when the drill string remains in the borehole, but not when the drill string is withdrawn from the borehole.
- the invention is based on the object of specifying a soil treatment device and a method with which a hole can be created in the soil in a particularly efficient manner.
- the soil treatment device is characterized in that a first pressure measuring device for measuring a first ambient pressure under the soil treatment device is arranged on a lower area of the base body, and in that a second pressure measurement device for measuring is arranged on an upper area of the base body, which is vertically spaced from the lower area a second ambient pressure is arranged.
- a basic idea of the invention can be seen in providing at least two pressure measuring devices on a base body of a soil treatment device.
- the pressure measuring devices are arranged in such a way that they are located in the borehole on a lower area of the base body and on an upper area of the base body.
- a first ambient pressure can be measured in a lower area of the base body and a second ambient pressure can be measured at a distance from it in an upper area of the base body in the borehole. Due to the fixed distance between the two pressure measuring devices, a comparison of the two measured ambient pressures must result in an essentially constant pressure difference, which depends on the consistency of the supporting liquid.
- Deviations from this pressure difference or between the measurements of the two pressure measuring devices enable statements to be made, for example, that a negative pressure is forming under the soil treatment device or that it is being filled of the body increases or decreases.
- the values or data from the pressure measuring devices can therefore be used for safe and efficient operation of the soil treatment device.
- the pressure measuring devices can be designed in any way, for example as electronic pressure sensors.
- a preferred embodiment of the invention consists in the first pressure measuring device and/or the second pressure measuring device having at least one hollow measuring body which is filled with a measuring fluid.
- the measuring body can be a tubular body or a measuring body composed of tubular bodies.
- a liquid or a gas can be provided as the measuring fluid. Water or an oil is preferably used as the measuring fluid.
- One or more sensor devices can thus be in protected contact with the measurement fluid.
- a particularly good pressure measurement can be achieved in that the measuring body has at least one flexible measuring surface which is in contact with the environment.
- the measuring surface can be a foil, a membrane or a fluid-tight fabric, through which an external ambient pressure can be transmitted to the measuring fluid through the supporting liquid or the soil material.
- the measuring surface can optionally be protected by a protective device, optionally a protective cover with a perforation, for example by a grid.
- the measuring body can be designed as any hollow body. It is particularly efficient that the measuring body is tubular.
- the measuring body can be made from tubular standard materials.
- the tubular measuring body can have a circular cross-section or a square or other polygonal cross-section.
- the measuring body is arranged essentially horizontally.
- the measuring body can preferably stretch horizontally partially or entirely around the circumference of the soil treatment device, so that a reliable pressure measurement can be carried out can.
- horizontally means an alignment approximately perpendicular to the longitudinal axis of the tillage tool and to the drilling direction.
- the invention can be realized by two or more separate pressure measuring devices, which can also have electronic sensors.
- a particularly efficient measuring arrangement consists in that the first pressure measuring device and the second pressure measuring device are fluidically connected via a connecting line and that a sensor device is arranged on the connecting line, with which a pressure difference between a first pressure at the first pressure measuring device and a second pressure can be detected at the second pressure measuring device.
- the pressure difference can be recorded as an alternative or preferably in addition to the two individual pressure measurements.
- a direct measurement of a pressure difference allows a particularly reliable statement as to whether, for example, a negative pressure builds up at the lower end of the soil working device, as can occur, for example, if the soil working device is pulled out of the hole too quickly.
- the soil treatment device can be designed in any way.
- the soil working device is designed as a removal drilling tool, a displacement drilling tool or a trench wall cutter.
- a removal drilling tool has material-removing removal elements on its underside, such as cutting teeth, chisels or roller bits.
- the drilling tool can be a drilling bucket, an auger or, in particular, another discontinuous drilling tool.
- the soil working device can be designed as a displacement drilling tool.
- a displacement drilling tool has at least one displacement surface which, when the drive rotates, displaces existing or removed soil material essentially radially into the wall of the borehole.
- a combination of a removal drilling tool and a displacement drilling tool can also be provided.
- the soil processing device can also be a trench wall cutter, which has at least one or preferably several cutting wheels at the lower end, which are driven in rotation about axes of rotation directed transversely to the advance direction.
- a hole or milled slot can also be created with an angular cross-section.
- the invention also includes a soil cultivation device, which is provided with the soil cultivation device described above for creating a hole in the ground, which is vertically adjustable and drivable.
- Such a soil cultivation device preferably has a carrier unit with an upper carriage which is rotatably mounted on a movable undercarriage.
- the undercarriage can in particular have a crawler chassis.
- the soil cultivation device can in particular be a drilling device or a trench wall milling device with a carrier unit.
- a substantially vertically directed mast is preferably arranged on the superstructure, along which the soil cultivation device is mounted so that it can be adjusted vertically.
- a control unit is provided which is in data connection with the first pressure measuring device, the second pressure measuring device and/or the sensor device.
- the control unit can document pressure profiles and/or control the processing device depending on the determined values and data.
- control unit is designed to control a vertical movement and/or a rotary drive of the soil treatment device depending on data transmitted from the first pressure measuring device, the second pressure measuring device and/or the sensor device. If, for example, an increase in the pressure difference between the two pressure measuring devices is determined, this can be an indication of the build-up of a negative pressure on the soil treatment device. In this case, a vertical movement, for example when pulling the device out of the hole, can be stopped or reduced until a pressure difference below a predetermined limit value is established again.
- a rotary drive for example in the case of a drill or a rotary drive on cutting wheels, can be changed depending on the pressure values, with e.g Pressure values can be a measure of how much and in particular whether too much or too little soil material is removed.
- a further preferred embodiment of the soil cultivation device according to the invention can consist in the control unit being designed to determine a degree of filling based on the data on the pressure on the soil cultivation device. If, for example, in the case of a drill bucket, the filling of the drill bucket with filling material increases, this can be determined from the determined pressure values, in particular from the lower first pressure measuring device. Basically, the pressure at the lower pressure measuring device increases with increasing filling level and thus with an increasing load of removed soil material.
- a certain limit value is reached, this can be taken as an indication that a sufficient filling level for a drill bucket has been reached.
- the hole is filled with a support liquid when it is created and a first ambient pressure in a lower region of the soil cultivation device is measured by means of the first pressure measuring device and a second ambient pressure in an upper region of the soil cultivation device is measured by means of the second pressure measuring device.
- the method according to the invention can be carried out in particular with the soil cultivation device described above or with the soil cultivation device described above. The advantages described above can be achieved in this way.
- An advantageous variant of the method consists in that the first pressure measuring device is fluidically connected to the second pressure measuring device via a connecting line and that a sensor device is arranged on the connecting line, with which a pressure difference between a first pressure at the first Pressure measuring device and a second pressure is detected at the second pressure measuring device. With the sensor device, a pressure difference between the two pressure measuring devices can be directly detected in an efficient manner.
- a soil treatment device 10 which is designed as a drilling bucket, is associated with the figures 1 and 2 explained.
- a tubular housing which surrounds a base body 12 has been left out of the soil treatment device 10 .
- a base 14 is arranged on the underside of the base body 12 and has a base removal device 30 on its underside. Removed soil material can be received in an inner receiving space on the base body 12 via an opening in the ground (not shown).
- the bottom 14 is mounted pivotably about a horizontally directed pivot axis 15 . So the bottom 14 can be pivoted down to empty the drill bucket.
- the housing around the base body 12 is closed at the top by a cover plate 18 on which a connecting device 20 for connecting to a drill rod is attached.
- the connecting device 20 is designed as a so-called Kelly box, which can accommodate a square-shaped end of a drill rod.
- a drill rod can thus be accommodated and fastened in the sleeve-shaped connecting device 20 in a rotationally fixed manner by means of transversely directed locking bolts.
- the soil treatment device 10 is provided with a pressure measuring arrangement 40 which has a first pressure measuring device 41 on a lower area of the base body 12 and a second pressure measuring device 42 on has an upper area of the base body 12 .
- the lower first pressure measuring device 41 has a first hollow measuring body 45a which is constructed in the form of a ring from three tubular elements.
- the outer measuring element pointing outwards is formed in an arc shape corresponding to an outer peripheral radius of the base body 12 .
- a flexible measuring surface 48 can be arranged in particular on an inside of the first hollow measuring body 45a, which deforms according to an external pressure due to the presence of supporting liquid, possibly with removed soil material, and thus transfers an external pressure to an internal measuring fluid.
- the first hollow measuring body 45a is formed parallel to the horizontal base 14 and can be in contact with an outside or an external environment via a recess in the base 14 .
- a corresponding recess is also formed in the cover plate 18 , a channel 17 being formed by an inner wall 16 along the base body 12 , through which support suspension can flow along the base body 12 .
- the upper second pressure gauge 42 has a second annular hollow gauge body 45b formed of four tubular members.
- the second hollow measuring body 45b extends in the form of a ring around the connecting device 20 on the upper side of the cover plate 18.
- the second hollow measuring body 45b is also designed with a flexible measuring surface for detecting an external ambient pressure, with the ambient pressure being able to be transferred to an internal measuring fluid.
- the first pressure measuring device 41 and the second pressure measuring device 42 are fluidically connected via a connecting line 44 which extends axially along the base body 12 .
- the inner wall 16 is provided, which largely delimits and protects the connecting line 44 and also the first pressure measuring device 41 on the floor 14 from removed soil material in the interior of the base body 12 .
- a sensor device 50 is connected to the connecting line 44 on the cover plate 18 and can be used to determine a pressure difference between the first pressure measuring device 41 and the second pressure measuring device 42 .
- the sensor device 50 can have a conventional pressure sensor or also a flow meter, which detects a movement of the measuring fluid in the pressure measuring arrangement 40 due to different pressures at the first pressure measuring device 41 and the second pressure measuring device 42 .
- pressure sensors can also be arranged on the two pressure measuring devices 41, 42, with which an absolute pressure can be determined in each case.
- the sensor device 50 and the additional sensors are connected to a control unit of a soil cultivation device, not shown, the control unit controlling a vertical movement of the soil cultivation device 10 and/or a rotary drive for turning the soil cultivation device 10 according to the determined pressure values.
- the pressure measuring devices 41, 42 are arranged on an outside. If it is desired to record the degree of filling, the first pressure measuring device 41 can be arranged in the inner receiving space of the base body 12 .
