Definitions

  • the invention relates to a method for compacting soils according to the preamble of patent claim 1 and to a system for compacting soils according to the preamble of patent claim 6.
  • a tool for example a shaker-lance set, is made to vibrate by vibration or oscillation and is sunk into the ground and withdrawn again several times and at certain intervals.
  • the vibrations of the vibrator-lance set briefly reduce the frictional force between the individual grains of the soil with the support of air and / or water.
  • the grains of the soil can then change into a more dense state of storage.
  • existing cavities in the subsoil can be reduced in size or completely closed.
  • a more dense storage of the soil is established.
  • the pore spaces between the soil grains shrink. This process is also called vibration pressure compaction.
  • the solidified soil which is more densely packed as a result, is suitable for carrying greater loads and is less sensitive to deformation.
  • the vibrating plug method is also particularly suitable for soil materials with a very high proportion of fine grain. With such materials, compaction of the subsoil itself is often no longer sufficient possible.
  • the vibrating pressure or vibrating plug process usually works in alternating steps. First, the vibrator-lance set is sunk into the ground and optionally water and / or compressed air is supplied to support the process. This is followed by a partial withdrawal, lingering, renewed withdrawal and renewed lingering, etc. according to a defined distance and a defined dwell time of the vibrator-lance set.
  • the addition of fluid supports the mobilization of the soil material during the various phases of the compaction process.
  • the continuous supply of backfill material into the space under and around the vibrator tip ensures that the volume deficit caused by the rearrangement is compensated.
  • the backfill material can be, for example, sand, gravel, crushed stone or concrete.
  • the step-by-step procedure gradually creates a stuffed column. This procedure is also known as the pilgrimage method.
  • the columns, sunk in a defined grid form a volume block of compacted soil. In larger areas, large, compacted areas are created using a large number of stuffing columns up to 70 m deep or more. The area can be of almost any size.
  • One challenge is to determine when the soil in a defined area of the column to be compacted has reached a sufficient degree of compaction. This determination is necessary in order to be able to weigh up when the respective process step can be ended. Since there are a large number of tamping columns or work positions in large areas, it is important to minimize the process time per work position so that the process time overall and thus the costs remain within an economical framework. At the same time, however, the process time per work position must not be too short to ensure that the soil is sufficiently compacted. Another challenge is to improve the soil compaction process itself. An important influencing factor here is that there is a defined and efficient input of energy into the soil.
  • the DE 198 22 290 C2 teaches a method for vibro-pressure and vibro-plug compression with the addition of media with a process-controlled vibrator.
  • the method is characterized by the fact that the supplied media are used both to drive the vibrator and to change the compaction of the material to be compacted.
  • a method for determining the density of the soil is disclosed.
  • the method provides for measuring the radial acceleration of the vibrator to determine the amplitude of the vibrator and measuring the rotational frequency and the depth of the vibrator.
  • the method then provides for calculating the storage density from the amplitude of the vibrator, taking into account stress-dependent soil parameters.
  • the DE 199 30 885 C2 and the DE 198 59 962 C2 describe further methods for compacting soils by means of a depth vibrator, in which conclusions are drawn about the degree of compaction of the soil by upgrading parameters of the depth vibrator.
  • the DE 199 28 692 C1 (Fellin 1999) finally describes a method for online compaction control of a soil, in which a continuous measurement of a tilt angle as well as a horizontal deflection of a vibrator tip and a leading angle of a vibrator unbalance takes place. The density of the soil is determined from this. The process is then continued until the desired storage density values are reached.
  • DE 196 28 769 A1 discloses a device and a method for deep compaction of cohesive and non-cohesive compaction material. It is intended that a vibrating tool be equipped with sensors. The measurement results of the sensors are transmitted. An electronic control system compares the measurement data measured by the sensors with measurement data provided by seismic measurements.
  • the object of the present invention is to provide an alternative method for compacting soils and a corresponding system in which the compaction is more efficient and faster and in addition an even more precise determination of the point in time at which the desired compaction state is reached is possible.
  • a first aspect of the invention relates to a method for compacting soils, in which a vibrating tool is sunk into the ground and a large number of state variables of the vibrating tool are measured with sensors during the compaction and at least some of the sensors are integrated in the vibrating tool, with further measurement data from the sensors are transmitted to a control device.
  • the control device compares the measurement data from the sensors with expected measurement data.
  • the expected measurement data are determined in a simulation that describes the interaction of the vibrating tool and the soil under given soil parameters.
  • the expected measurement data represent at least one state variable of the soil and describe a defined target state of the soil that is to be achieved in the method.
  • the recorded measurement data represent the respective actual characteristics of the state variable (s) of the soil surrounding the vibrating tool, and are related to the actual properties of the soil.
  • the actual state variables change continuously during the process starting from the initial state of the surrounding soil towards the defined target state.
  • the expected measurement data which for example represent the soil mechanical parameters of the defined target state, are continuously compared according to the invention with the recorded measurement data until the target state is reached.
  • the concept of the state variable encompasses both extensive and intensive state variables.
  • extensive state variables are characterized in that they are of a Depend on the number of system elements of the system under consideration (for example volume).
  • Intensive state variables are independent of the number of system elements in the system under consideration (e.g. temperature).
  • Position, speed, vibration amplitude, deflection in the vertical direction and acceleration in the region of a vibrator tip and in an area above a drive motor for an imbalance are preferably measured as state variables of the vibrating tool.
  • the term above refers to a side of the drive motor that faces a heavy pipe of a lance set.
  • the bearing temperatures of the imbalance (s) and motor (s) are preferably recorded.
  • a torque as well as a motor frequency and an angle of rotation of the drive motor are also preferably recorded.
  • a temperature of an oil for lubricating the bearings of the drive motor and possibly the unbalance is also one of the preferably recorded state variables of the vibrating tool.
  • the temperatures of other elements of the vibrating tool are also preferably recorded.
  • a test current of the vibrating tool is preferably also recorded to determine, among other things, an electrical ground resistance.
  • preferably recorded state variables of the vibrating tool are, for example, pressures and volume flows of fluids, such as water or air, passed through the vibrating tool, as well as a theoretical load on the vibrator (residual load or hook load). The mentioned examples of state variables of the vibrating tool are not conclusive and can be adapted as required.
  • the competent specialist takes these measures independently, depending on which state variables he needs in order to derive certain state variables of the soil.
  • a large number of the sensors, with which these state variables are measured, are preferably integrated in the vibrating tool. These can be acceleration sensors, temperature sensors, current sensors and sensors for recording fluid pressures and volume flows. Some sensors can also be integrated in a carrier device of the vibrating tool. For example, sensors for detecting a vibration depth or a hook load could be mentioned here.
  • Measurement data from the sensors are transmitted to the control device by means of a suitable line for transmitting information, for example via an optical fiber.
  • the expected measurement data, with which the measurement data of the sensors are compared, are determined according to the invention from a simulation which describes an interaction of the vibrating tool and the soil under given soil parameters.
  • the expected measurement data is based on an interaction between the vibrating tool and the soil, with the condition of the vibrating tool being described as completely and realistically as possible using the condition variables of the vibrating tool, and a resulting condition of the soil, also as completely and as possible, with knowledge of a characteristic of the existing soil is expressed realistically on the basis of state variables of the soil.
  • Expected measurement data are preferably kept ready which represent a large number of state variables of the soil.
  • Such intensive or extensive state variables of the soil can for example be a grain size, a storage density and a degree of compaction, a temperature, an electrical conductivity, a water content, a consistency and other state variables for soils known to the person skilled in the art.
  • This is also, for example, a significant improvement over the above DE 199 28 692 C1 which describes only one method of controlling the storage density.
  • the present method according to the invention offers the possibility of setting the state of the soil in a much more comprehensively defined manner.
  • the DE 199 28 692 C1 also records a large number of additional measurement data on the jogging tool, such as the temperature.
  • the method according to the invention offers the advantage that, by including a large number of state variables of the vibrating tool and determining a large number of expected measurement data for the respective soil when it interacts with the vibrating tool in the method according to the invention, extensive and very precise knowledge about the im The actual state of the soil can be derived in the course of the procedure. This knowledge can be used to advantage in order to compact the soil efficiently and quickly. It is also possible to precisely determine the point in time at which the floor has reached its desired state.
  • control device uses the comparison to control and / or regulate the compaction of the soil towards the target variables to be achieved.
  • a deviation of the measurement data from the sensors from the expected measurement data serves as the control variable.
  • the control or regulation of the compression process takes place on the basis of the control variables determined by correlating the recorded and expected measurement data.
  • a lateral acceleration of the vibrator tip can be detected with the sensors.
  • a volume flow and a pressure of a fluid supplied to the ground by the vibrating tool can be recorded.
  • fluids increase the mobility of the soil.
  • the mobility of the soil can in turn be inferred from the measurement data recorded by the sensors or from a transverse acceleration profile of the vibrator tip. If this transverse acceleration profile now deviates from an expected transverse acceleration profile with a defined supply of fluid, the pressure and the volume flow of the fluid can be regulated accordingly until the transverse acceleration profile corresponds to the expected transverse acceleration profile.
  • a multi-body simulation is preferably used to simulate the interaction of the vibrating tool with the ground.
  • a continuum simulation is preferably used on the ground. Both simulations are preferably combined with one another for a holistic description of the method.
  • the energy input into the soil can also be simulated particularly advantageously from this. The aim is to reproduce the process as realistically as possible.
  • the required soil parameters can for example be determined in the context of soil investigations and / or empirically.
  • the soil parameters of the simulation are adapted by evaluating the measurement data of the sensors and the simulation is then repeated at least once.
  • a project-specific verification and calibration of the simulation is preferably carried out before the method is carried out for the first time with a specific soil. If there are major deviations, the underlying model can be revised accordingly. Furthermore, a plausibility check of the comparison of the measurement data from the sensors with the expected measurement data is preferably carried out. For example, suitable plausibility checking algorithms can be used to determine if a sudden solidification of the soil is not based on a success of the method carried out but, for example, on a larger stone lying in the way or even a densely packed soil. Here, for example, acceleration sensors and temperature sensors on the vibrating tool can provide corresponding measurement data. By intelligently combining the measurement data, it is then possible to quickly determine whether the soil is tightly packed or whether there is just a stone.
  • the simulation takes place in real time.
  • real time in the context of the present invention means that the method for compacting soils of the invention is controlled or regulated in such a short time that in practice a sufficiently fast reaction to changing measurement data from the sensors or comparison results of the measurement data with the to expected measurement data is possible.
  • a control cycle is run through preferably 30,000 times per second, so that a control frequency results.
  • one or more fluids and / or filler material are supplied to the soil.
  • the method according to the invention can thus advantageously be operated both as a vibrating plug process and as a vibrating pressure process.
  • a further aspect of the invention relates to a system for compacting soils, at least comprising a vibrating tool that can be sunk into the ground, a plurality of sensors which are designed to measure state variables of the vibrating tool during compaction, at least some of the sensors being integrated in the vibrating tool , as well as a control device.
  • the control device is designed to carry out a comparison of the measurement data from the sensors with expected measurement data, the expected measurement data representing at least one state variable of the soil.
  • the control device is designed such that a simulation of an interaction of the vibrating tool and the soil is carried out under given soil parameters and the expected measurement data are determined from a result of the simulation.
  • the system of the invention is designed in particular to carry out the method according to the invention for compacting soils in accordance with the description above. All of the disclosed technical features and advantages of the method according to the invention also apply accordingly to the system according to the invention.
  • control device is designed such that control and / or regulation of the compaction of the soil is implemented to the desired extent on the basis of the comparison.
  • control device is designed to adapt the soil parameters of the simulation while evaluating the measurement data of the sensors and then preferably the simulation to repeat at least once.

  • the expected measurement data are determined in a simulation.
  • the expected measurement data describe an interaction of the vibrating tool 12 and the soil 10 under given soil parameters. In the first method step, there is still no significant interaction between the vibrating tool 12 and the floor 10.
