  • the invention relates to a deformable foundation formwork for the production of an underground foundation, in particular an underground pile foundation or an underground support foundation having a tie rod or a pressure rod.
  • the invention further relates to a method for producing an underground foundation, in particular an underground pile foundation or an underground support foundation having a tie rod or a pressure rod.
  • the invention relates to a method for producing a pile structure for transferring loads from a structure to a ground, with the steps: producing an underground foundation, in particular an underground pile foundation, and producing a pile on the underground foundation.
  • expander bodies made of steel For the production of underground foundations, expander bodies made of steel have so far been used, which are inserted in a folded state into a borehole in the ground and expanded by pressure filling with a cement mortar.
  • the expander bodies made of steel are complex and expensive to produce.
  • the expander bodies made of steel entail high material and manufacturing costs as well as high transport weights.
  • the processing of the steel sheet and the bending process regularly lead to significant environmental pollution.
  • Expander bodies made of steel also have the disadvantage that they cannot be restored or repaired if damaged or leaked. Furthermore, if a defect occurs, an at least partially expanded expander body cannot be removed from a hole prepared for the expander body and replaced with an undamaged expander body, so that a new hole is usually required if defects occur during assembly.
  • the object underlying the invention is to simplify the production of underground foundations.
  • the object is achieved by a deformable foundation formwork of the type mentioned at the outset, the deformable foundation formwork according to the invention having a flexible material-receiving textile, which is designed to be positioned within a borehole made in a ground and to be pressure-filled within the borehole with a hardenable material mixture.
  • a pile foundation or a support foundation having a tie rod or a pressure rod can be produced.
  • Such foundations can be used, for example, in pile and anchor construction, in building construction with deep foundations or in dam construction on soft ground, as well as in the production of supporting structures.
  • fabrication or adjustment of the foundation formwork can be done directly on site, allowing for modifications based on local observations, field measurements and/or drilling data.
  • the damaged foundation formwork can be removed from the borehole and replaced so that the Foundation construction can be continued with new foundation formwork without the need for a new borehole.
  • the deformable foundation formwork allows a flexible installation process, which significantly reduces the uncertainties regarding the complete expansion of the foundation formwork.
  • the material receiving textile of the deformable foundation formwork is preferably made of a flexible geotextile.
  • the curable material mixture can be, for example, a soil-binder mixture, concrete or synthetic resin.
  • the material receiving textile forms a flexible container for the material mixture.
  • the material receiving textile provides a filling volume for receiving the curable material mixture. Due to the flexibility of the container formed by the material-receiving textile, the foundation formwork can adapt to the borehole contour when pressure-filled with the material mixture, so that the borehole contour is subjected to substantially uniform pressure when the material-receiving textile is pressure-filled. This also results in a uniform material displacement in the contact areas between the material receiving textile and the borehole contour.
  • the foundation formwork preferably has a filling opening through which the filling volume of the material receiving textile can be filled with the material mixture.
  • the material receiving textile is stretchable.
  • the material absorbing textile consists at least partially of biodegradable fibers. During pressure filling, the material absorbing textile can be pressed onto the borehole wall.
  • the material receiving textile can be made from natural fibers and/or synthetic fibers.
  • the material receiving textile can be a fiber fabric or have twisted and/or stranded filaments.
  • the material receiving textile may include carbon fibers, plastic fibers and/or steel fibers.
  • the material-receiving textile has a longitudinal extension and is designed such that it maintains the longitudinal extension during pressure filling with the material-receiving mixture.
  • the material absorbing textile is therefore not shortened when pressure filling with the material mixture. There is no reduction in length. In contrast to the use of expander bodies made of steel, which experience a reduction in length during pressure filling, no secondary injection of a curable material mixture is required to fill any gap below the filled material-receiving textile, which would result from a shortening during the filling process.
  • the foundation formwork according to the invention is further advantageously developed in that the material receiving textile is designed to be liquid-permeable.
  • the liquid permeability allows, for example, the controlled outflow of concrete milk from the material-receiving textile, so that a particularly stable connection is implemented between the expanded material-receiving textile and the surrounding soil. Due to the permeability, it is also possible to inject biological soil improvement solutions into the ground through the foundation formwork before the material receiving textile is filled with the material mixture. For example, injecting soil improvement solutions can sustainably improve the shear strength of the soil near the foundation formwork.
  • the material absorbing textile can also be impermeable to liquids.
  • the material receiving textile is made of a liquid-impermeable material or has a liquid-impermeable coating or material layer.
  • the material receiving textile may comprise a liquid-impermeable nonwoven material layer or a liquid-impermeable plastic material layer.
  • the use of a liquid impermeable material absorbing textile is advantageous in applications where no outflow is desired or required, for example when the subsurface foundation is to be created in a saturated clay soil.
  • the material receiving textile forms a double-layer outer shell.
  • the double-layered outer shell significantly increases the load capacity, so that the material absorbing textile can be filled with particularly high pressures.
  • the double-layered outer cover is achieved, for example, by folding or folding the material-receiving textile.
  • the material-receiving textile has one or more seam areas within which sections of the material-receiving textile are sewn together.

  • the flexibility of the material absorbing textile is provided by the lower end element with a high-strength finish.
  • the lower end element can be disc-shaped or cap-shaped.
  • the end element can be in one piece or in several parts. Alternatively or in addition to a lower end element, a lower region of the material receiving textile can also be knotted, clamped or glued.
