Definitions

  • the invention initially relates to a method for introduction of piles tapering in the direction of insertion the ground, which is used to support or support buildings or building parts, in particular building foundations serve (preamble of claim 1).
  • Such, in the Piles also called “nails” by experts are from DE-PS 194 125 in the form of hollow ramming piles tapering downwards known from reinforced concrete. According to the title cited above In this patent, these piles are said to be in the ground be rammed in.
  • steam-driven battering rams usual ramming of piles, sheet piling and the like referred to by steam-driven battering rams.
  • This composition of the pile to be driven in from several Elements has the further disadvantage that the elements shift at their junctures can, or that the junction from the flight of the Elements to the side, so that the entire pile in has one or more kinks.
  • the aforementioned are often Shifts or kinks after insertion of the concrete pile can no longer be determined and therefore a permanent threat to the structure supported by it represent.
  • WO 94/17252 discloses piles and methods which should contribute to an improvement of the foundation. To do this, use a slightly tapered pile Hammering or vibration driven into the ground. The created hole is either directly with cement or similar poured out or struts first inserted and then poured cement into it.
  • the task or problem of the invention is in contrast, initially in a procedure for collecting of piles according to the preamble of claim 1 in to create the earth with a relatively small Work and material expenditure is feasible, the so driven piles under the one resting on them No or practically no longer set the building load, i.e. not penetrate further into the ground, which is a corresponding lowering (settlement) of the building in question would result.
  • the piles reciprocate in their longitudinal direction Vibrations and in this way initially in the Earth can be driven to a position that is short before reaching its intended final depth it is convenient that the vibrations are then switched off and then a final phase of driving in by application a vibration-free force acting in the driving direction on the pile until it is pre-tensioned is firmly held in the ground.
  • This bias can also be seen as a wedging or bracing of the pile be understood with the adjacent soil.
  • the bringing in such piles by means of in their longitudinal direction and vibrations are compared to the known Ramming cheaper because it is essential with a less equipment expenditure and also one essential less noise can occur.
  • a preferred embodiment of the method according to the invention is the subject of claim 2 the pile is not under the longitudinal vibrations or -vibrations set, but by means of an appropriate Tensile or compressive force over a portion of its length in depressed the ground. It is therefore relative to the earth firmly held so that the on it in its longitudinal direction acting vibrations can not lead to it moved aside or even damaged.
  • the invention further relates to the configurations from Concrete or reinforced concrete existing piles for the implementation of the method according to the invention can be used can. For this purpose, reference is made to claims 3 to 11.
  • the concrete piles are over their entire Length with a tapered or arched downward Provide taper.
  • the surfaces roughened the outside of the piles or there are there deepenings.
  • the piles take on their diameter viewed from the bottom up constantly. This has a constant displacement of the soil with the introduction of the piles. It will also hold the Piles in the ground with the pretension explained in claim 1 further consolidated.
  • the further in such piles provided roughening or deepening support the The piles in question stop in or on the side of the ground.
  • Claim 5 gives the Possibility of inclining or tapering the piles in Dependence on the consistency of the respective soil choose. This tendency can be around 2-6%.
  • Claim 7 includes a preferred embodiment of the Invention for creating outer surfaces or sides of the Concrete pile, which have roughening and / or depressions.
  • the claims 9 and 10 allow the attachment both a vibrator as well as a foundation, e.g. one Support plate.
  • the principle of driving the piles 1 into the ground 2 is shown in Figs. 1-4.
  • the stake in question 1 is with a only schematically indicated bracket 3 in placed vertically on the ground 2 and then by a pushing or pulling force according to arrow 4 over a Section 5 of its total length L pressed into the ground. This indentation is vibration-free or vibration-free.
  • the upper end face 6 of the Pile 1 a vibrator, here only schematically indicated vibrator 7, placed in the, not shown Way connected to the upper portion 8 of the pile 1 and this in its longitudinal direction A-B according to the Arrows 9 swings up and down until it is the one shown in FIG Has reached the driving position.
  • the pile 1 is tapered downwards. He can any cross-sectional shape, e.g. square or rectangular 7 have. He could also use an oval instead or have a circular cross-section. Furthermore, the Post 1 "trumpet-like" towards its upper end face expand as it is by the dash-dotted lines Lines 12 in Fig. 1 is indicated above.
  • piles have one Design of the taper of its outer sides in such a way that after driving in and final impressions in stick the earth to it.
  • the rejuvenation of the Piles depending on the consistency of each Soil can be chosen, in such a way that with harder The inclination of the outside of the concrete pile whose longitudinal central axis A-B is smaller and a softer one In contrast, soil is larger.
  • the Inclination of each of the outer sides of the pile 1 in question its longitudinal central axis A-B is about 2 to 6%.
  • the task of Invention roughened the surfaces of the outside of the piles or be provided with depressions. This will further their liability or friction on the surrounding Soil increased. For this it is recommended to use the concrete piles to produce from a porous concrete material, the the aforementioned porosity the roughening or indentation forms.
  • the piles 1 are made of concrete or reinforced concrete. You can also hollow and be made from a porous concrete, so that through its hollow interior (not shown) about the porous concrete in the ground is sucked off can be. This reduces the on very damp floors Risk of excessive slipperiness on the outside of the pile on Ground.
  • FIGS. 5 and 6 schematically show arrangements and Devices shown to the piles according to the invention in the Bring in soil.
  • 5 is a smaller one, off-road vehicle 14 at the construction site by means of Common, hydraulically operated supports 15 supported and possibly held firmly by a ballast 16. It carries a via only schematically indicated struts 17 likewise only schematically indicated bracket 18, in the a hydraulic system 19 is attached.
  • the movable part 19 ' this hydraulic is fixed in a manner not shown the upper region of the vibrator 7 connected via a only indicated connection 20 at the upper area 8 of the pile 1 attacks.
  • the hydraulics 19 ensures the so-called Preload, i.e. the last vibrationless impression of the Pile 1 into the ground from the position shown in FIG. 3 in that of Fig. 4.
  • FIG. 6 shows the Post 1 before it is placed in the ground. This matches with 1.
  • the second cable 26 is moved by the roller 29 of the tractor and overflows another pulley 30 of leader 23, which as well the aforementioned pulley 28 in the upper area is appropriate.
  • the cable 26 runs from the deflection roller 30 to a lower guide roller 31 of the leader and from there back up to the vibrator 7. This cable serves at corresponding drive via the roller 29, via which then not operated vibrator the pole 1 from the position 3 to the end position shown in FIG. 4, i.e. to give him the pretension already explained.
  • Both the device 14 and the tractor 21 are because of required off-road capability with a caterpillar drive Mistake.
  • Fig. 7 shows the possibility of executing one of the piles 1 in perspective. From this is both the Taper the pile from its top face 6 to to its lower end face 13 as well as a rectangular one or square cross-sectional shape. It could but also an oval or circular cross-sectional shape be provided.
  • the cast-on pin 35 can be gripped of the pile by a crane or to connect to the Serve vibrator.
  • FIG. 8 shows in this example a top view of part of the bottom 2 with a total of nine piles 1, each of which is the upper one End faces are recognizable. What to apply to this The foundation is for the sake of simplifying the drawing only indicated by dash-dotted lines in FIG. 8.
  • FIG. 9 shows a view in the direction of arrow 32 with cast foundation 33.
