Definitions

  • the invention relates to a device for forming a soil element in the ground, comprising a drilling rig with a drill drive, by which a drill auger with a hollow inner tube can be driven in a rotating manner, wherein a borehole can be created in the ground by the drill auger while removing soil material, a feeding device for feeding a curable mass through the hollow inner tube and an outlet opening at a lower end region of the drill auger into the borehole when the drill auger is withdrawn from the borehole, a pressure sensor for detecting the pressure of the curable mass during feeding, and a control device for controlling a withdrawal movement of the drill auger during feeding of the curable mass, according to the preamble of claim 1.
  • a device of the same type is, for example, made from the US 6 116 819 A known.
  • the invention further relates to a method for forming a soil element in the ground, wherein a drill auger with a hollow inner tube is driven by a drilling drive of a drilling rig, wherein a borehole is created in the ground by the drill auger while removing soil material, a curable mass for forming the soil element is fed into the borehole through the hollow inner tube and an outlet opening at a lower end region of the drill auger by means of a feeding device when the drill auger is withdrawn from the borehole, the pressure of the curable mass is detected by means of a pressure sensor during feeding, and a withdrawal movement of the drill auger is controlled by means of a control device when feeding the curable mass, according to the preamble of claim 9.
  • Such a soil element can be, for example, a foundation pile, a retaining pile or a column, which serves, for example, to improve the soil.
  • a generic device and a generic method are derived from the EP 0 842 329 B1
  • a borehole is first drilled using an auger.
  • the auger serves to remove the soil material and simultaneously transport it upwards.
  • This well-known method allows for uncased drilling, as the borehole wall is supported by the auger's auger, which is filled with soil material, during the drilling process.
  • the control system determines a volume to be filled by an inflow of concrete, depending on the geometric characteristics of the auger, in particular the auger diameter and the resulting borehole diameter, and the auger's retraction speed.
  • the known drilling device incorporates a flow meter on the feed hose to the auger to measure the concrete flow, and a pressure sensor above the drill drive, which drives the auger below, to measure the concrete pressure.
  • the established method generally yields good results under stable soil conditions.
  • problems can arise if the borehole passes through one or more layers of permeable soil or soil containing cavities. In such soil conditions, filling the borehole may require [a specific method/appliance - context needed].
  • a significantly higher demand for curing compound arises because a considerable portion of it flows out of the borehole area and penetrates adjacent soil layers. This can lead to an improperly constructed soil element with defects, thus impairing its load-bearing capacity. This may necessitate the installation of additional foundation piles or the costly removal and reconstruction of a defective soil element.
  • the invention is based on the objective of providing a device and a method with which a soil element can be created in the ground in a particularly reliable and economical manner.
  • the device according to the invention for forming a soil element in the soil is characterized in that the pressure sensor is arranged at the lower end region of the auger, in particular at the outlet opening for the curable mass, that the control device has a storage unit in which at least one setpoint for a pressure as the target pressure in the area of the outlet opening for the curable mass during feeding is stored, and that the control device is connected to the pressure sensor and is designed to control the retraction movement of the auger and/or a feeding of curable mass by the feeding device in such a way that, during retraction, a pressure of the curable mass in the area of the pressure sensor corresponds to the predetermined target pressure.
  • a fundamental aspect of the invention is that the pressure of the concrete mass at the lower end of the auger is crucial for determining the actual amount of curing material required to form the floor element.
  • This pressure is measured directly at the lower end of the auger and indicates whether the borehole is actually filled or whether curing material is flowing into any existing void in the ground. In the latter case, the pressure is significantly lower than the target pressure, which is particularly relevant when constructing the floor element under stable geological conditions.
  • This actual pressure at the borehole cannot be measured by a pressure sensor located far away, such as on the drill drive.
  • the pressure sensor is connected to the control unit, which is configured to control the retraction movement of the auger and/or the feeding of curable material by the feed device in such a way that the pressure measured by the pressure sensor corresponds to a predetermined setpoint pressure stored in the control unit.
  • control unit configured to control the retraction movement of the auger and/or the feeding of curable material by the feed device in such a way that the pressure measured by the pressure sensor corresponds to a predetermined setpoint pressure stored in the control unit.
  • "corresponding to a setpoint pressure” is to be understood as a setpoint pressure range that includes a certain pressure tolerance both above and below this range.
  • the device according to the invention can reduce or, in extreme cases, stop the retraction movement of the auger and/or increase the supply of curing material through the feed device until the pressure sensor measures a pressure corresponding to the predetermined target pressure.
  • the control system can then increase the retraction movement again or reduce the supply of curing material through the feed device.
  • a Control of the retraction movement of the auger and/or the supply of curable mass dependent on the pressure of the curing mass.
  • a high-quality, defect-free floor element can be achieved through the appropriate use of a curing compound, in particular a concrete compound.
  • the curing compound is a suspension of liquid and solids, preferably a cement-based suspension.
  • a soil element within the meaning of the invention can, in particular, be a foundation pile, a retaining pile, or a column that contributes to improving a property of the soil or the ground, especially to improving its load-bearing capacity and/or stability.
  • the soil element can, in particular, serve as a foundation element or other structural element in the soil and be designated as such.
  • a preferred embodiment of the invention consists in the at least one setpoint being formed by a setpoint curve in which the setpoint pressure depends on the depth position of the outlet opening.
  • the setpoint pressure achieved during the creation of the base element can increase with increasing depth, since increased pressure may be exerted on the concrete mass from above.
  • the setpoint pressure to be achieved can thus gradually decrease. This applies particularly when the pressure sensor is arranged in the area of the liner tube at the lower end of the auger.
  • a further development of the invention provides that the control unit detects the depth position of the outlet opening. This can be determined, for example, by detecting the position of the drill drive along the mast, since the length of the auger is a known fixed value. Depending on the depth position of the outlet opening on the auger, the control unit can determine and set the current target value for the pressure at the given depth using a stored control program. A depth-dependent target value is advantageous for supplying the curing material according to demand.
  • the control system can store information about the soil geology, and in particular the soil layer structure of the soil in which the soil element is created.
  • the soil geology especially a soil profile, is typically determined in advance by a soil survey at construction sites where foundation piles are required. These values can be entered from a central location via remote data transmission or directly by a machine operator.
  • the control system can determine a target pressure curve that depends on the soil profile.
  • a particularly preferred embodiment of the invention consists in the control device being designed to detect soil layers, especially their thicknesses and types, during the drilling process.
  • the auger is used to create the borehole for the soil element.
  • torque, feed force, rotational speed, and/or feed rate can be detected. Based on these detected parameters, conclusions can be drawn about the soil structure and the strength of individual soil layers.
  • a soil profile with its soil layers can be determined for each specific borehole and stored in the control unit. This can preferably be done in combination with a pre-stored soil profile, allowing for a particularly precise determination of the layer boundaries for the specific borehole.
  • This soil structure, determined during borehole creation, can then be directly incorporated into the second process step of creating the soil element by introducing the curable material at an adjusted target pressure.
  • control unit has a storage unit in which data on soil layers, in particular their layer thicknesses and types, are stored.
  • a storage unit or database can be used, in particular, for evaluating the data recorded during drilling and assigning it to specific soil layers. This allows a specific soil profile with the individual soil layers, their layer thicknesses, and type or composition to be determined with particular reliability for each borehole.
  • a support unit with a mast is provided, along which the drill drive for rotating and moving the auger is movably mounted and guided.
  • the mast can, in particular, be a so-called mast with a linear guide for a guide carriage on which the drill drive is arranged.
  • the drill drive enables the auger below to be driven in rotation and moved axially, particularly vertically.
  • a feed movement and a retraction movement of the drill drive, and thus of the auger can be controlled via the guide carriage and a corresponding traverse drive.
  • the invention further comprises a method for forming a soil element in the soil, characterized in that the pressure sensor is arranged at the lower end region of the auger, in particular at the outlet opening for the curable mass, that the control device has a storage unit in which at least one setpoint for a pressure as the target pressure in the area of the outlet opening for the curable mass during feeding is stored, and that the control device is connected to the pressure sensor and controls the retraction movement of the auger and/or a feeding of curable mass by the feeding device in such a way that, during retraction, a pressure of the curable mass in the area of the pressure sensor corresponds to the predetermined target pressure.
  • the method can be carried out in particular with the described device.
  • the advantages outlined can be achieved.
  • a preferred embodiment of the invention consists in the control device controlling the retraction movement of the auger and/or the supply of curable material through the feed device depending on the depth position of the outlet opening. This allows for consideration of a suspension pressure that changes with depth, thus enabling a particularly demand-oriented supply of the curable material.
  • control device regulates the retraction movement of the auger and/or the supply of curable material by the feed device depending on the type of soil layer.
  • a setpoint can be specified not only for a depth but also for the type of soil layer present in the area of the discharge opening. Particularly in the case of a soft soil layer, a reduction of the setpoint for the pressure can be advantageous in order to counteract excessive displacement of curable material into the soft soil layer. This results in a particularly economical use of the curable material.
  • the soil layers can be stored in the control unit, particularly as soil profile data.
  • a particularly preferred embodiment of the invention consists in the control unit recording soil layers, especially their thicknesses and types, during the drilling process. Even during drilling, the control unit can record certain operating parameters, in particular the torque and feed force at the drill drive, as well as the rotational speed and feed rate of the auger.
  • the control unit is equipped with a corresponding program and a database of comparative data, enabling the creation of a soil profile across the drilling depth based on the recorded operating parameters. This can be used to determine a target value profile for the subsequent process step of introducing the curing compound.
  • the detection and determination of a soil profile by the control unit can also be used in combination and for comparison with the already stored data on a soil profile.
