Definitions

  • the invention relates to a method for producing a support structure, in particular for supporting and/or securing a terrain change of artificial or natural origin. Furthermore, the invention relates to a support structure, in particular for supporting and/or securing a terrain change of artificial or natural origin. In addition, the invention relates to the use of a slipform paver for producing a support structure, in particular for supporting and/or securing a change in terrain of artificial or natural origin.
  • the supporting body is not designed as a so-called padded wall, in which the reinforcement elements are raised and folded back at the front, but with the help of the aforementioned outer skin elements, which are planned to be used for load transfer, any reinforcement layers are to be connected to these in a force-fitting and form-fitting manner.
  • the object on which the invention is based is therefore to simplify and/or speed up the supporting and/or securing of a terrain change of artificial or natural origin.
  • a slipform paver is used to produce a plurality of supporting bodies positioned one above the other in layers.
  • Slipform work can be carried out at a comparatively low cost and time. This means that the construction time is significantly reduced when manufacturing or erecting the support structure, while at the same time a highly resilient and permanent site security is implemented. Due to the mechanical and continuous execution, this construction also allows an improvement in the compaction in the Front area, but at least a comprehensible and consistent quality. Support bodies produced by means of a slipform paver also allow optimization of the required use of materials, so that there are also considerable savings in terms of material costs. Overall, there is a significant reduction in the overall costs for corresponding support structures.
  • the terrain change can be an embankment or a slope.
  • the change in terrain can also have been artificially created by bulk materials or waste.
  • the support structure that can be produced using the method can be a support structure.
  • the several support bodies positioned one above the other in layers preferably form a multi-layer support wall or a multi-layer front wall on a change in terrain, in particular an embankment or on a slope.
  • the support structure can also be referred to as a multi-layer support wall, multi-layer front wall or multi-layer sliding wall.
  • the support bodies produced can be, for example, massive heavyweight bodies or comparatively slender plate bodies.
  • the slipform paver uses a slipform to produce support bodies, with several or all of the support bodies positioned one above the other being produced using the same slipform. Since the supporting bodies have the same cross-sectional profile or the slipform paver uses the same slipform to produce the supporting bodies, it is not necessary to change the slipform of the slipform paver during erection of the supporting structure. Depending on the design of the slipform paver, more or less time-consuming disassembly and assembly work on the slipform paver is usually not required, so that the erection of the supporting structure is accelerated.
  • the slipform paver can be equipped with an adjustable slipform so that supports with different cross-sectional profiles can be used with the adjustable Slipform can be produced without having to change the slipform on the slipform paver.
  • the first, ie the bottom support body and/or the last, ie the top support body can have a cross-sectional profile that differs from the cross-sectional profile of the support bodies arranged between the bottom and the top support body.
  • the method according to the invention is further advantageously developed in that supporting bodies positioned one above the other are produced with an offset, in particular a horizontal offset, with respect to one another.
  • the horizontal offset is preferably achieved in that the movement paths traveled by the slipform paver when producing the supporting bodies also have a horizontal offset. Due to the horizontal offset, an inclined surface, in particular a continuously inclined surface, can be produced on the front side of the support structure.
  • a method according to the invention is advantageous in which several or all of the supporting bodies produced by means of the slipform paver and/or the slipform used by the slipform paver to produce the supporting bodies have a cross-sectional profile which has an inclined end surface at the front.
  • the front end surface can also run vertically or essentially vertically.
  • the front end surface of the support body can be smooth or rough.
  • the front end surface of the support body can be flat, curved or wavy.
  • the aesthetics of the front can be improved by subsequently attaching facade panels, natural stones or other architecturally sophisticated lightweight construction elements to the front end surface.
  • color pigments can be added to the material from which the supporting bodies are produced by the slipform paver, in order to achieve a front end surface with an intended coloring.
  • the supporting body material can also be mixed with seed, growth substrate and/or fertilizer so that on the front end surface after the construction of the supporting structure, a rapid greening or a rapid emergence of the plants is achieved.
  • the cross-sectional profile of the support body produced and/or the slipform used by the slipform paver to produce the support body can have, for example, a vertical closing surface on the back.
  • the cross-sectional profile of the support bodies produced and/or the slipform used by the slipform paver to produce the support bodies can have a horizontal end surface on the upper side and/or on the underside, for example.
  • the method according to the invention is further advantageously developed in that several or all of the support bodies produced by means of the slipform paver have a cross-sectional profile with a stop contour.
  • Support bodies positioned one above the other can be brought into abutment with one another via the stop contour.
  • the stop limits or prevents a frontward horizontal movement of at least one of the supporting bodies that are in contact with one another.
  • the slipform used by the slipform paver to produce the support body also has a cross-sectional profile with a corresponding stop contour.
  • the stop contour can be formed by a material step on the top or bottom of the support body.
  • the supporting bodies produced by means of the slipform paver can have a shearing step or a shearing edge, ie a so-called shear key, which prevents frontward horizontal movements of the supporting bodies.
  • the method according to the invention is further advantageously developed in that several or all of the supporting bodies produced by means of the slipform paver have a cross-sectional profile with an engagement contour, via which supporting bodies positioned one above the other are brought into engagement with one another.
  • the engagement limits or prevents frontward or rearward horizontal movement of at least one of the engaged support members.
  • the slipform used by the slipform paver to produce the support body also has a cross-sectional profile with a corresponding engagement contour.
  • the engagement contour can a Include web of material on the top or bottom of the support body.
  • the engagement contour preferably has a receiving groove, which corresponds to the material web, on the opposite side of the support body.
  • the engagement of support bodies arranged one above the other can thus be implemented by a material web engaging in a receiving groove.
  • the transfer of shearing force between the support bodies can also be improved by additionally inserting shearing pins and/or shearing force dowels.
  • the material from which the supporting bodies are produced comprises microorganisms which produce precipitations which change the properties of the material.
  • the precipitates altering the properties of the material are calcium carbonate precipitates.
  • This microorganism-based precipitation of calcium carbonate is referred to as microbially induced calcite precipitation (MICP) or biocementation.
  • MIMP microbially induced calcite precipitation
  • biocementation biocementation
  • Cohesion in the front area of the support structure can also be achieved via the carbonate precipitation, so that the stability and erosion resistance of the support structure are ensured.
  • the microbially induced calcite precipitation can be used to fix pollutants or prevent their spread.
  • cement or polymers as binders can be dispensed with in some applications.
  • the method according to the invention is further advantageously developed in that the microorganisms producing the precipitations are metered into the material from which the supporting bodies are produced by adding biomineralization.
  • the biomineralization supplement can be liquid or dry.
  • the biomineralization supplement has a powder or granular form.
  • the dosing is done for example by a dosing device of the slipform paver or by an external dosing device which is not part of the slipform paver. If an external dosing device is used, the slipform paver can already be fed with a material containing the microorganisms. A homogenization of the material comprising the microorganisms after metering in the addition of biomineralization can take place through the slipform paver and/or beyond the slipform paver.
  • the slipform paver is already loaded with a material that has been homogenized and contains the microorganisms. External homogenization is carried out, for example, using a separate truck mixer.
  • the slipform paver can have a mixing device for homogenizing the material comprising the microorganisms.
  • the mixing device may comprise an auger.
  • the material from which the support bodies are produced comprises soil material, a soil/binder mixture and/or concrete.

  • the slipform paver can either be equipped with a storage container for the supporting body material, or the slipform paver is provided with the supporting body material, in particular continuously, while the supporting bodies are being produced by an accompanying vehicle.
  • the slipform paver may include a conveyor for conveying the support body material to the slipform.
  • the slipform paver can use a conveyor belt or a pipe system, for example.
  • the support bodies can also be equipped with reinforcement elements.
  • the reinforcement elements can, for example continuously placed by the slipform paver in the area enclosed by the slipform. Alternatively, the reinforcement elements can be positioned along a path of extension of the supporting body before the production of the supporting body, so that the sliding formwork runs over them during the production of the supporting body.
  • the support structure can be a concrete barrier. After concreting, joints are preferably cut on the surface of the concrete safety barrier in order to produce a uniform joint or crack pattern on the wall surface.
  • the slipform paver can also pave several, for example two, materials at the same time.
  • a particularly drainable material such as drainage gravel
  • the support body designed as a front element and made of a soil material, a soil/binder mixture and/or concrete.
  • a method according to the invention is advantageous in which one or more reinforcement elements, in particular geogrids, are arranged between supporting bodies positioned one above the other.
  • the one or more reinforcement elements serve in particular to absorb tensile forces and are preferably flat reinforcement elements.
  • the reinforcement elements can also be designed, for example, as a fabric, steel mat, or reinforcement strip.
  • the one or the plurality of armor members may be partially or fully formed of plastic.
  • the one or more reinforcement elements can comprise textile material and/or be made of synthetic fibers.
  • the one or more reinforcement elements can also consist of unprotected or corrosion-protected steel or natural materials.
  • the one or more reinforcement elements can be designed over the entire area or in the form of strips. For example, the reinforcement elements are designed as strips, rods or strands. Ground anchors can also be considered as reinforcement elements.
  • Reinforcement elements are preferably inserted continuously across the width of the front. Due to the continuous insertion of the reinforcement elements across the front width and the superstructure, no elements with a concentrated load application, such as eyelets, dowels, anchors, are required. In this case, the effort and costs for individual anchor points do not apply. However, individual anchor points or attachment points can be provided directly, so that they do not have to be drilled in or dowelled afterwards.
  • the back area of the support body produced last is first filled with filling material before a further support body is produced above the support body produced last.
  • the filling material can be filling soil or gravel sand, for example.
  • the filling material can be compacted during or after being placed in the rear area of the support body produced last.
  • the support body is constructed in terms of its geometric dimensions and its density or by previously described measures for removing shear stresses in the contact area of the support body such that the earth pressure generated as a result of the compaction energy can be removed.
  • the rear area of the support body produced last is preferably filled with filling material up to approximately the overall height of the support body produced last.

  • the slipform paver is a self-propelled construction machine which preferably moves along a terrain change of artificial or natural origin while the supporting bodies are being produced.
  • the slipform paver preferably has its own drive, via which the slipform paver can traverse the support body extension paths in the respective layers or planes for producing the support body.
  • the slipform paver can be an add-on machine which is to be attached to a carrier vehicle or towing vehicle in order to travel along the support body extension paths.
  • the slipform paver moves during the production of a supporting body partially or completely on the filling material with which the rear area of the last produced supporting body was filled with filling material, or on a reinforcement element arranged on the filling material, in particular a geogrid. Since the filling material in the rear area of the support body is also filled in layers or floors, there is always a new roadway for the slipform paver after the respective filling processes, which can be used by the slipform paver when producing the next higher support body.
  • the level on which the slipform paver moves can also be higher than the level on which the supporting body is to be manufactured. In this case, the supporting bodies are produced as part of an underfloor production.

  • the slipform paver automatically controls and/or regulates one or more machine parameters influencing the material compaction during the production of the supporting bodies.
  • the compaction performance can be controlled by the machine parameters and can therefore be understood and is therefore not dependent on the individual quality of manual compaction. Furthermore, there is no need to carry out compaction tests on a regular basis, which is difficult and takes a lot of time and costs. By reading out the machine parameters or a suitability test or work instructions previously carried out for the bulk material, the material compaction can be understood much better. There is quality assurance with regard to the material compaction, which does not lead to any significant time delay in the construction process.
