Definitions

  • the invention describes the foundation device for transportable and temporary flood protection.
  • long tubes with a diameter of 1 m and more are laid, which are filled with water and thus form a water barrier.
  • Other constructions are that inclined plates or pallets, which can be supported by columns obliquely, are coated with films and thus provide a seal against the flood.
  • the object of the invention is to enable the economical use of safe, transportable flood protection walls with simple and inexpensive foundation measures.
  • FIG. 1 shows a vertical section through the device according to the invention.
  • a non-reinforced mixed-in-place wall 21 are at a distance 16 support members 22 which protrude beyond the surface 26 of the mixed-in-place wall 21.
  • a continuous head bar 23 made of concrete, which consists of a reinforcing cage 27 and are integrated in the connecting elements 24.
  • columns 25 can be fastened non-positively to these connecting elements 24, between the dam beams 28 can be hung.
  • Figure 2 shows a rotated by 90 ° to Figure 1 out, vertical section.
  • FIGS. 3 to 5 show an embodiment variant according to the invention of mounting elements 14, from which the carrier elements 22 can be formed.
  • Figures 6 to 8 show horizontal sections through the mixed-in-place wall 21, in which different trained support members 22 are set, which in turn consist of combinations of the mounting element 14.
  • FIG. 9 shows a variant in which the mixed-in-place wall 21 essentially consists of individual slots 31 for the carrier elements 22.
  • Suitable foundation measures for such flood protection walls would be winkeising walls, secant bored pile walls, concrete slot walls or continuous sheet piling. Temporary protective walls could be securely fastened to these foundation measures.
  • the invention therefore describes an economical as well as safe system with which temporary flood protection walls can be erected.
  • the attachment of the temporary flood protection walls takes place in such a way that initially as a foundation and sealing wall unweighted mixed-in-place wall 21 is produced by the mixed-in-place process.
  • the soil in question is converted into a soil mortar by one or more rod-shaped agitators or slit-wall cutter-like devices in the soil.
  • water, binder and possibly additives or bentonite is added via the stirring tools or milling and mixed in this way the pending soil to a soil mortar.
  • These support elements 22 are designed so that they can absorb vertical forces, horizontal forces and bending moments and can dissipate via the mixed-in-place wall 21 in the ground.
  • carrier elements 22 it is preferred to use rolled carriers such as IPB carriers, double U carriers, tubes, sheet piles, bars, plates or combinations of these agents.
  • prefabricated concrete columns or precast concrete piles are introduced into the slot filled with floor mortar, which have a free connection reinforcement on the air side.
  • a particular variant of the invention is that for the support elements 22 mounting elements 14 and combinations of these mounting elements 14 are used ( Figure 3 to Figure 8).
  • Such mounting elements 14 are particularly inexpensive compared to rolling beams and complicated welding devices.
  • the elements 14 consist of substantially mutually parallel longitudinal bars 1, 1 ', 1 "..., which are non-positively connected by zig-zag or wavy arranged diagonal bars 2.
  • a steel bar may be formed zigzag or wavy over a longer range ( Figure 3) or single diagonal bars 2 'or individual substantially triangular curved bars 2 "are used ( Figures 4 and 5).
  • Static requirements may require that the longitudinal bars be connected to each other on two sides or through several layers of diagonal bars (Figure 8).
  • welds 4 are preferably arranged in the arcs or tips of the diagonal bars 2 and the dimensions of the diagonal bars 2 are chosen so that the Longitudinal bars 1, 1 '... are as far outside as possible in the wall and thus larger bending moments can be absorbed.
  • the inclination angles ⁇ , ⁇ ', with which the diagonal bars 2 run towards the longitudinal bars, are preferably in the range between 30 ° and 60 °.
  • the diagonal bars 2 between the longitudinal bars 1, 1 ' should be as straight as possible.
  • FIG. 5 shows a variant embodiment in which elements 14 are arranged triangular in relation to one another on the left side. On the right side, two elements 14 are combined to form a triangular element 19, in which a longitudinal bar 20 and longitudinal bars 1 'are non-positively and statically operatively welded to one another via two or more diagonal bars by welds 4, 4'. It may be expedient that in this case the size of the cross-sectional area of the longitudinal bar 20 is different than the cross-sectional area of the longitudinal bars 1 '.
  • the longitudinal bars 1, 1 '... and the diagonal bars 2 are preferably made of profiled or ribbed structural steels with circular cross sections. In principle, however, all cross-sectional shapes are conceivable.
  • the embodiment of the elements 14 can be made both of smooth steels, but preferably of steels, which have a certain roughness by mechanical processing or coating, which causes higher adhesive stresses in the floor mortar.
  • each element 14 Preferably, only one earth-side bar 1 and one air-side bar 1 'are arranged on each element 14, whose cross-sectional areas can also vary.
  • the later-mounted flood protection walls are higher, it may be expedient to equip the elements 14 with a plurality of longitudinal bars 1, 1 ', 1 "for static reasons (FIG. 8).
  • the diagonal bars can also be welded between the longitudinal bars (FIG. 5).
  • the elements 14 are preferably installed vertically and aligned so that their larger expanse area comes to lie across the plane of the mixed-in-place wall.
  • angles ⁇ and ⁇ 'of these surfaces to the wall normal are preferably in a range between -45 ° and + 45 °.
  • At least two or more elements 14 are combined with one another at the locations of the concentrated introduction of force.
  • the elements 14 are introduced into the freshly prepared mortar only after preparation of the mixed-in-place wall 21, which is done by pure impressions or slight vibration, the elements 14 by suitable binding plates 3, 3 ', 5 in their arrangement to each other be fixed.
  • the elements 14 are connected by constructive welds or by binding wire with the binding plates.
  • the binding plates can also be replaced by rods.
  • the binding plates 3, 3 ', 5 are arranged at intervals of about 0.5 to 2 m.
  • the dimensions of the elements 14 are chosen to have sufficient steel coverage through the floor mortar within the mixed-in-place wall 21. It lies in the centimeter range.
  • a reinforcing cage 27 is arranged in the head region 29 of the support elements 22, which connects the individual heads of the support elements 22 so that after concreting the head beam 23 vertical forces, horizontal forces, bending moments and Torsionsmomente of these can be included.
  • the heads 29 of the support members 22, the reinforcement 27 and the connecting members 24 are concreted into the concrete of the head beam 23, the head beam concrete being substantially waterproofed to the surface 26 of the MIP wall.
  • the reinforcing cage 27 is formed in the formation of the longitudinal bars and brackets so that it can transmit forces that are introduced to the connecting elements 24, via torsion in the heads 29 of the support elements 22.
  • the connecting elements 24 are preferably made of screws, threaded sleeves, Absteckbolzen, Absteckhülsen or from bayonet-like elements, which are directly or indirectly connected with tension or pressure anchoring elements according to the state of anchoring technology, as they are known from the reinforced concrete composite construction.
  • Such anchoring elements 30 are z. B. expansion anchor, Flachfußanker, Plattenfußanker or steel elements with holes through which rebars are pulled.
  • the transmission takes place essentially via torsional forces in the head beam.
  • the support elements 22 in turn direct the forces into the unreinforced mixed-in-place wall 21 and from there they are removed into the ground.
  • An elaborate fastening technique of the connecting elements 24 is the dimensionally accurate direct or indirect welding of the connecting elements 24 to the reinforcing bars 7 of the head bar or to the connection reinforcement 29 of the carrier elements 22.
  • the connecting elements 24 are sunk into the head bar 23 so that they can be protected in flood-free times by cover plates.
  • the columns 25 are fastened with screws, nuts or bayonet-type connecting means frictionally to the connecting elements 24.
  • the surface of the head bar at least partially smooth, flat and horizontal form.
  • the upper edge of the head beam is preferably arranged level with the terrain.
  • the mixed-in-place wall 21 can be made as a continuous wall or consist of individual slots 31 which are located only in areas where the support members 22 are provided.
  • the slots 31 extend into greater depths, so that the horizontal forces can be removed from the water pressure in the ground.
  • the foundation device according to the invention for transportable, temporary flood protection walls is an economical, inexpensive and equivalent solution.
