Definitions

  • the invention relates to a civil engineering method for creating a columnar structure in the ground, in which a civil engineering tool is driven to rotate about an axis of rotation and introduced into a ground with a feed, the columnar structure being created in the ground, according to the preamble of claim 1.
  • the invention further relates to a construction device for creating a columnar structure in the ground, with a civil engineering tool which can be driven to rotate about an axis of rotation by means of a rotary drive and can be moved into the ground by means of a feed drive in a feed direction, at least one detection device for detecting a rotary movement of the civil engineering tool and a feed movement and at least one sensor device for detecting at least one further operating parameter, according to the preamble of claim 10.
  • a generic civil engineering method and a generic construction equipment go from the EP 2 806 070 B1 emerged.
  • a high-pressure injection body is created in the ground by means of a drill rod which has an outlet for ejecting an injection medium into the ground.
  • a gyroscopic measuring means is provided on the drill rod for detecting a direction of movement of at least a part of the drill rod caused by the ejection of the injection medium.
  • An electronic evaluation means makes it possible to assign the depths of propagation of the injection medium determined to the current output direction.
  • the injection medium By rotating the drill string with the outlet, the injection medium is delivered radially around the drill string into the ground. It is possible to first erode the soil with a high pressure water jet and then expel the injection medium into the environment, which consists of eroded soil and water. By lifting the drill rod with the outlet, an approximately cylindrical high-pressure injection body (HDI body) can be formed.
  • HDI body high-pressure injection body
  • HDI bodies or HDI columns are used for various purposes.
  • a subsoil can be consolidated or sealed against the ingress of groundwater.
  • HDI bodies can be used to connect different wall types, for example pile walls and sheet piling.
  • the injection medium can in principle be any fluid or any liquid or suspension, which can also be mixed with solids.
  • a cement suspension, chemicals or synthetic resins can be used.
  • the dimensions of the HDI body actually produced must match the desired dimensions sufficiently. This is of particular importance if several HDI bodies are to provide a seal next to one another in the floor. In this case, there must be no free space between the HDI bodies.
  • an HDI body in particular in the radial direction to the drill pipe, can, however, vary depending on the soil. For example, an obstacle in the ground can prevent the injection medium from penetrating. As a result, an HDI body produced does not usually have an exact cylindrical shape. Rather, its radial extent is dependent on the depth and the azimuthal angle. This indicates a direction in a plane perpendicular to the drilling axis.
  • HDI bodies In order to nevertheless provide a sealing effect with HDI bodies, these are usually created with an overlap in the floor.
  • the overlap is selected to be larger, the more uncertain the knowledge of the dimensions of the HDI bodies. This increases the number of HDI bodies to be erected, which is associated with a greater time requirement and higher costs.
  • measuring devices are used.
  • the erection of an HDI body is monitored with a geophone. This is driven into the ground at a distance from the drill pipe. By detecting ground vibrations, the range up to which the injection medium is expelled can be estimated.
  • Driving in a geophone represents an additional amount of work, which increases the time required and the personnel requirements. In addition, the accuracy that can be achieved in this way is limited.
  • the measuring device there comprises a sound transmitter and receiver.
  • the emitted sound is reflected back at a boundary surface of the borehole, in particular with an injection body.
  • the radial extent of the borehole or the depth of propagation of the injection medium can then be determined from the transit time of the sound signal.
  • the measuring device comprises a spool with an unwindable measuring line. By detecting the extent to which the measuring line has unrolled, conclusions can be drawn about the radial dimensions of the high-pressure injection body.
  • the method according to the invention is characterized in that, when creating the columnar structure, a rotary movement and a feed movement of the civil engineering tool are recorded over time and forwarded to an evaluation unit, that at least one further processing parameter for creating the columnar structure in the ground over time is detected and forwarded to the evaluation unit and that a three-dimensional model of the columnar structure is created and displayed by the evaluation unit.
  • One aspect of the invention is to acquire certain measured values over time in a civil engineering method for creating a columnar structure in the ground and to use them to create and display a three-dimensional model of the columnar structure created in the most descriptive way possible.
  • the three-dimensional model of the columnar structure created does not have to be a true-to-scale model of the columnar structure actually created in the ground, such as a foundation pile. It is essential that the three-dimensional model produced can clearly show the correct implementation of the civil engineering process and possible defects in the structure produced.
  • a rotary movement of the rotating civil engineering tool and, at the same time, a feed movement of the civil engineering tool are recorded over time.
  • At least one further processing parameter is recorded over time, which is essential for creating the columnar structure in the ground.
  • the evaluation unit can then create a clear three-dimensional column model of the columnar structure and display it directly on a display device on an operating or monitoring station, for example directly in the construction equipment.
  • a machine operator can be shown immediately if the created columnar structure has an undesirable flaw in the floor. With this immediate display, the machine operator can immediately, in particular as long as an introduced cement suspension has not yet hardened, a Carry out rework with the civil engineering tool. Such prompt troubleshooting is much easier and more cost-effective to carry out than if a defect is only found in the floor when the structure is finished and cured.
  • any columnar structure can be created in the ground, such as an HDI element for an injection anchor or a lime or gravel column. It is particularly preferred according to the invention that a foundation pile is created in the ground as a columnar structure.
  • the foundation pile is produced by material-removing drilling or by displacement drilling, a hardenable suspension being introduced into the drill hole produced.
  • a drilling tool with an injection opening or an injection lance for injecting a hardenable suspension is used as the civil engineering tool and that a hardenable suspension is introduced into the ground by the rotating civil engineering tool to create the columnar structure .
  • the borehole can be created at the same time and the hardenable suspension can be introduced in the same or a subsequent operation.
  • the drilling tool executes a helical movement with the injection opening, which is produced by a superposition between a rotary movement and a feed movement.
  • each parameter can be recorded when creating the columnar structure in the ground, which allows a statement to be made about the created structure in the ground. It is particularly advantageous that an injection pressure, a pump pressure, an injection volume, a temperature, a tool deflection and / or a sound measurement value is recorded as at least one further operating parameter. These parameters can be recorded individually or in any combination with one another and used to generate the three-dimensional model. A particularly good statement about the introduction of a hardenable suspension can be recorded by measuring a tool deflection or a sound, as is the case, for example, in the documents mentioned in the introduction to the description EP 2 896 070 B1 respectively DE 196 22 282 C1 and is also known in principle to an average person skilled in the art.
  • the evaluation unit forms a helical time axis as a function of the rotational movement and feed movement recorded over time and that the at least one processing parameter recorded over time for forming the three-dimensional model is assigned to the helical time axis.
  • the evaluation unit combines the determined rotary movement and the determined feed movement in such a way that no linear, straight time axis is formed, but a helical time axis.
  • the central axis of the helical shape can preferably be a measure of the distance covered, that is to say the depth in the ground. If the at least one further parameter is now plotted over the helical time axis, this results in a clear representation that allows direct comparisons to the column structure actually created in the ground and, in particular, allows deviations and flaws to be easily identified.
  • the three-dimensional model of the columnar structure is formed by interpolation by the evaluation unit after the at least one processing parameter has been assigned to the helical time axis.
  • the areas missing between the screw turns are mathematically determined by corresponding interpolation of the operating parameters that are opposite in the axial direction on the adjacent turns of the helical time axis.
  • a linear interpolation is preferably provided here. In this way, a spatial, columnar model can be created relatively easily from a linear acquisition of a parameter.
  • a preferred variant of the method also consists in that the rotary movement is detected directly on a rotary drive or by a speed measuring element on the civil engineering tool.
  • the speed measuring element can in particular be a speedometer.
  • the rotary movement can also be picked up directly by a tachometer on the rotary drive.
  • the feed movement can be measured in any suitable manner. It is particularly preferred that the feed movement is detected directly on a feed drive or by a displacement measuring element on the civil engineering tool.
  • a particularly efficient civil engineering method is achieved according to a further development of the invention in that a three-dimensional target model for the columnar structure to be created in the ground is stored in the evaluation unit, and that the three-dimensional model determined for the columnar structure as an actual model by the evaluation unit is compared with the target model and that deviations between the target model and the actual model are displayed on a display device.
  • These deviations can be viewed as flaws, especially if the outer circumference of the actual model does not correspond to the target model with its outer circumference.
  • These flaws can preferably be shown on a colored display with a different color, for example the color red. A flaw or an insufficient formation of the columnar structure in the floor is thus immediately apparent to a machine operator.
  • the depth at which there is a defect in the created columnar structure in the ground can also be determined directly. In this way, the machine operator can remedy this defect immediately by means of post-processing.
  • the construction device is characterized in that an evaluation unit is provided which is connected to the at least one detection device and the sensor device, the evaluation unit being designed to create a three-dimensional model of the columnar structure based on the recorded data, and that a display device is provided with which the created three-dimensional model of the columnar structure can be displayed.
  • the construction device can in particular be a drilling device for creating a foundation pile in the ground or an injection anchor.
  • the civil engineering tool is a drilling tool with an injection opening or an injection lance for injecting a curable suspension.
  • a measured value is preferably used as a further processing parameter, which represents a measure for the curable suspension introduced per time and place.
  • a further advantageous embodiment of the drilling device according to the invention is that a speed measuring element is provided with which a rotational movement of the civil engineering tool can be detected over time, and / or that a displacement measuring element is provided with which a travel path of the civil engineering tool can be detected over time.

  • the injection opening 20 can be rotated together with the civil engineering tool 10 or independently thereof about an axis of rotation 14, also called the drilling axis. This creates a columnar structure 32 which surrounds the rod-shaped civil engineering tool 10.
  • the ejected injection medium 22 penetrates up to a propagation depth 28.
  • the propagation depth 28 is a radial distance which can be determined from the injection opening 20 or from the axis of rotation 14. Due to obstacles in the ground, the size of the propagation depth 28 can depend on the azimuth angle about the axis of rotation 14 and / or on the height of the injection opening 20 along the axis of rotation 14.
  • a sensor device 40 is arranged on the civil engineering tool 10 so that it rotates with it. This receives a measurement signal, for example a sound signal.
  • the injection noise can be used as the sound signal, or an acoustic signal can be transmitted with a transmitter, the reflections of which are measured as a sound signal by the sensor device 40.
  • the signal can in particular be reflected back at an interface between the injection medium 22 and the soil 3.
  • the associated azimuthal direction is also determined, which indicates a rotational position of the injection opening 20 about the axis of rotation 14.
  • gyroscopic measuring means 30 can be provided on the rod-shaped civil engineering tool 10. These detect a direction of movement 26 of at least part of the civil engineering tool 10. This movement is caused by the ejection of the injection medium 22. Therefore, an ejection direction 24 and the direction of movement 26 of the drill rod 10 are exactly opposite to one another.
  • an electronic evaluation unit can be calculated from the measured values of the gyroscopic measuring means 30 of different ejection or output directions 24 of the injection opening 20.

It shows Fig. 2 The sound intensity I measured periodically per revolution over a time axis t, which represents a measure of the depth of propagation of the injection medium 22 and thus as a measure of the external shape of the columnar structure 32 created in the ground.
  • the columnar structure 32 can in particular be a foundation pile in the ground 3.
  • the raw data curve which is not very meaningful, is transferred to a helical time axis t, which is shown schematically in FIG Fig. 3 is shown.
