Definitions

  • the invention relates to a method for securing retaining walls with soil behind it, bores being drilled through the retaining wall and cavities in the soil being flushed out behind the retaining wall by means of high-pressure water jets, and reinforcing bars with cement material being used in the cavities.
  • the earth pressure can be intercepted by removing the soil behind the retaining wall and erecting an angled retaining wall there, so that the old retaining wall only represents a facing brickwork.
  • the object of the invention is to provide a method of the type mentioned in such a way that an effective securing of the retaining wall is achieved with little effort in terms of work and material, without this having to be converted into a heavyweight wall to absorb the entire earth pressure.
  • the ground anchors arranged in a suitable distribution take over the earth pressure and thus relieve the load on the retaining wall. There is a self-supporting needling of the earth's body without static participation of the retaining wall while maintaining the old structure.
  • the force of the earth pressure is introduced into the ground anchors through their thickened heads (load distribution elements) on the back of the wall, which form load distribution bodies.
  • FIG. 1 which is, for example, an old stone wall with soil 2 behind it, is first cleaned of soil material, vegetation and organic constituents on the accessible wall surfaces. All loose and damaged parts are removed and the areas to be grouted are cleaned by high pressure water jets and sand blasting, so that a clean contact surface with open pores is created.
  • the masonry core is solidified by stabilizing and gluing the wall structure by pressing a trass lime suspension. Thanks to the highly flowable trass lime suspension, which is compatible with the old joint, all cavities in the retaining wall are pressed. These renovation measures give the masonry a self-contained structure and thus at least corresponds in its strength to the original condition.
  • holes 3 are made in the retaining wall 1 at a distance next to one another and possibly also offset from one another, preferably in the lower third point, which are preferably inclined at most 15 ° to the horizontal.
  • the diameter of these holes is 80 mm, for example.
  • a load distribution cavity 6 is flushed out on the back of the retaining wall 1, said cavity being essentially flat on the back of the wall and having, for example, a diameter of 50 cm and a depth of up to 50 cm .
  • the water accumulated in the load distribution cavity 6 during flushing and the soil dissolved therein is sucked off by means of a suction hose.
  • an anchor hole 7 is subsequently rinsed out in the soil 2 in the extension of the bore 3.
  • the anchor hole 7 has a diameter of 80 mm, for example; its length depends on the static requirements, which are essentially determined by the soil mechanics. The length is, for example, 2 to 4 m. This state is shown in Fig. 2.
  • a reinforcement rod 8 (needle anchor) is inserted through the bore 3, for example a ribbed reinforcement steel with a diameter of 22 mm. Spacers hold the reinforcement bar 8 in the center of the anchor hole 7. The reinforcement bar 8 extends into the hole 3 (FIG. 3).
  • a filler bore 9 which opens obliquely downward into the load distribution cavity 6, is drilled through which cement material, for example a highly flowable cement suspension or cement mortar, is introduced. This cement material completely fills the anchor hole 7 and the load distribution cavity 6 and the bore 3. Then the hole 3 and the filling hole 9 are closed by mortar.
  • cement material for example a highly flowable cement suspension or cement mortar
  • the inserted reinforcing bar 8 forms, together with the cement material surrounding it, a nail-shaped or needle-shaped ground anchor 10, the head 11 of which forms a load distribution element which absorbs the earth pressure and introduces it into the ground anchor 10.
  • the retaining wall 1 is largely relieved of earth pressure in this way.
  • the ground anchor 10 By extending the ground anchor 10 into the assigned flushing hole 3 of the retaining wall 1, the latter is connected and additionally stabilized after relief from the earth pressure.
  • the refurbished retaining wall 1 shown in Fig. 4 after completion of the work is secured against the effects of earth pressure and only has to carry itself.
  • the original structure of the retaining wall 1 has been fully preserved.
