Definitions

  • the invention relates to a method for the remediation of Retaining walls by means of ground anchors, which go through the retaining wall in the growing soil behind it and possibly as Rock anchor driven into the rock behind and be anchored.
  • the known Procedure is also not sufficient if the composite the retaining wall to be renovated, at least in some cases Areas are hardly given and / or essential Refurbishment measures also required on the front of the wall are, for example in concrete retaining walls, where the Visible side sanded, falling and missing binder exposed.
  • the object of the invention is therefore a method of train the type mentioned in such a way that with relative Complete renovation with little effort also made possible by heavily damaged retaining walls.
  • a precast slab in front of the retaining wall Foundation pillar is set that the gap between the Retaining wall and the precast slab is poured with concrete and that the ground anchors through anchor holes in the precast slab and inserted through the retaining wall and against the Precast panel to be clamped.
  • the concrete filling resembles unevenness, external damage and deformations or displacements that have already occurred the retaining wall, so that no renovation measures the retaining walls themselves are required.
  • foundation pillars essentially only the weight of the prefabricated precast slabs and the leveling concrete few, statically narrow dimensions are sufficient Foundation pillars made in simple ways in boreholes can be used or built in this.
  • the earth pressure acting on the retaining wall to be renovated transmitted through the ground anchors into the grown soil, so that no increased foundation effort for the transfer of Vertical forces on the foundation pillars are required.
  • Adjacent prefabricated panels are preferably shear-resistant interconnected to create cutting forces between adjacent ones Transfer wall sections.
  • the manufacture of the foundation pillars that like axial stressed piles are dimensioned for load transfer, is relatively easy because of the weight to be absorbed is low and mostly in the frost-free depth considerable soil strength only small dimensions of the Foundation pillar required.
  • the Foundation pillars as prefabricated parts made of concrete or steel be driven dynamically.
  • Foundation pillar made of in-situ concrete can easily be inserted in boreholes, which because of the Capillary cohesion is temporarily stable.
  • Combination designs are possible, for example with a gradually widened by displacement and repeatedly filled with dry mortar under Use of a pneumatic hammer.
  • the precast panels After installation, the precast panels become temporary supported until the concrete in the possibly reinforced joint filled between the precast slab and the retaining wall and is sufficiently hardened. This can be done through a conventional support on the outside of the plate. Instead, it is a further embodiment of the inventive concept also possible using the precast panels Connection parts, preferably dowels, with the retaining wall to connect provisionally before grouting the joint with concrete becomes. This eliminates the need for additional support measures.
  • the precast slab and / or the leveling concrete can also be used a reinforcement.
  • the precast plate in their manufacture to provide perforated anchor heads through which the ground anchors be introduced. These anchor heads are used for introduction the anchor forces in the usually relatively thin Precast panels.
  • the drawing shows one in a vertical section renovating retaining wall 1, in the illustrated embodiment a concrete wall with an angular foundation 2.
  • foundation pillars 5 inserted in boreholes 3 in the bottom 4, which up to frost-free depths are enough.
  • it is prefabricated foundation pillars made of concrete or steel. So far required, the foundation pillars 5 with pillar heads 5a made of concrete, steel or with a connecting reinforcement, Mistake.
  • a static Reinforcement for the leveling concrete layer on the retaining wall mounted using dowels or the like. Then be on the Foundation pillars 5 each in front of the front Retaining wall 1 precast panels 6 set. This is what it is about are, for example, semi-finished concrete slabs with a Reinforcement 7 are provided.
  • the precast panels 6 have perforated anchor heads 8.
  • precast panels 6 For temporary stability of the precast panels 6 can this by means of connecting parts, for example dowels 9, be connected to the retaining wall 1. Instead, or in addition, it is also possible to attach the precast panels 6 support their front. Then the one between the Retaining wall 1 and the prefabricated panels 6 existing, possibly reinforced gap 10 with a concrete filling shed.
  • the vertical force that occurs is shown in the foundation pillars 5 removed while the horizontal force in the ground anchor 12 is removed.
  • the Refurbishment can be carried out relatively quickly and requires little intervention in the area surrounding the renovating retaining wall 1. This also meets the requirements environmental protection and soil protection better taken into account than with conventional methods.
