Definitions

  • the invention relates to a method for producing a superimposed bored pile wall, with an insertable into a subsoil auger and a drive for rotating and advancing the auger into the ground, said auger at least one extending in a longitudinal direction of the auger helix and cutting tools for cutting and / or has cutting and / or cutting processing of the substrate.
  • a pile is drilled with a hollow auger and, after reaching a desired depth by concrete supply via a running in the auger core tube of the auger while simultaneously extracting the auger concrete.
  • the upper end with a conventional concrete pressure transducer is permanently connected to a supply line for fresh concrete.
  • the borehole wall is supported by the soil filled flights.
  • Auger bored piles are always concreted up to the surface of the terrain in order to enable a subsequent insertion of a reinforcement.
  • This reinforcement is set in these piles immediately after concreting in the fresh concrete shaft of the pile, possibly with a light pull-in or Rüttel Anlagen.
  • the reinforcement may be tapered downwardly to allow central penetration into the fresh concrete of the bored pile.
  • a usual pile production takes place with a complete and as automated as possible and quality assured drilling data acquisition.
  • This drilling data acquisition u.a. the drilling progress, the production period, the rotation of the auger, the concreting pressure and the concrete quantity are recorded.
  • the present invention has the object to provide a method for producing a screw boring pile, according to which a particularly fast production of screw bored piles is possible in a particularly large number of different substrates with structurally simple means.
  • the auger pile is a secondary pile of a superimposed bored pile wall.
  • the auger pile is a secondary pile of a superimposed bored pile wall.
  • two primary piles can be cut by means of cutting tools.
  • intermediate surfaces of the produced gates can be milled off at the primary piles during insertion of the auger.
  • the cutting tools are arranged at least in sections on the outer edge of the at least one helix.
  • the cutting tools can be arranged in greater density or at a greater distance from each other.
  • the configuration of the helix and in particular the placement of the helix with cutting tools on the outer edge can be implemented as required and also taking into account economic aspects with more or less cutting tools.
  • the auger may have two spirals. These may be in the sense of a Double helix can be arranged with two simple spirals running around each other. Such a structure may also be referred to as a double-threaded screw. Such a double helix structure is particularly favorable when introduced into inhomogeneous substrates, since the symmetrical arrangement of the helixes largely prevents a sideways running of the auger. A secure positioning of a bored pile is thereby made possible.
  • the cutting tools arranged on the outer edge can extend substantially radially to the longitudinal direction of the auger.
  • This radial arrangement has the advantage that when cleaning a Bohrschnecke conventional screw cleaner - unhindered by the cutting tools - can be used.
  • the Schneckenputzer arrive here in concrete without hindrance in the spaces between the helices.
  • the cutting tools can have interchangeable cutting elements and / or change lugs.
  • worn or worn cutting tools can thus be a simple restoration of the functionality of the device - by a simple exchange - achieve.
  • Elaborate welding work for attaching cutting tools to the helix can be dispensed with.
  • the auger may have a guide element for guiding the auger when introduced into the ground.
  • a targeted introduction of the auger is possible even with inhomogeneous ground.
  • different substrate materials can be considered.
  • the guide element can be arranged or formed on a head region or milling head of the auger or on a front end of the at least one helix.
  • the guide element may preferably have cutting tools to undertake a background machining during the guiding function.
  • a head portion of the auger or the at least one helix may have a preferably double-edged cutting bar.
  • a cutting bar can serve not only to work the substrate, but also to provide a guide for the auger.
  • the cutting strip can serve firstly for cutting the primary piles adjacent to the secondary pile to be produced. Immediately after the cutting of the primary piles can be done by the primary piles guide, since the cutting bars can be performed by the recesses produced in the primary piles in their rotary motion.
  • Such a cutting bar may extend along a predeterminable section or along predeterminable sections of a diameter of the auger.
  • the cutting bar can extend substantially to the outer edge of the diameter, for example, to be guided substantially in recesses in primary piles, which are produced in the production of a secondary pile in the adjacent primary piles.
  • a cutting bar along a diameter of the auger may extend just enough to fit exactly between two primary piles. As a result of this, a guiding function is achieved when introducing the auger between the primary piles.
  • a central line for fresh concrete to be introduced is formed in the longitudinal direction of the auger, two cutting strips can be realized, each extending between about the inner pipe and each a primary pile.
  • a cutting bar in each case can be formed on a helix at the front end thereof, so that when two helixes are realized in the auger, two cutting bars can assume a guiding function which extends in a symmetrical manner along a diameter of the auger.
  • the at least one helix in a front region of the helix with a be formed along at least a portion of the diameter gradually decreasing diameter.
  • the at least one helix may be tapered conically or conically at its front end.
  • too many cutting elements or cutting tools mean a cross-sectional constriction, which can lead to a feed reduction.
  • the helices can shred the above when cutting into a primary pile cross-section above it upwards.
  • Fig. 1 shows a first embodiment of a portion of a drilling auger 1 of a device according to the invention for producing a screw boring pile.
  • the device has an insertable into a substrate drilling screw 1 and a drive not shown here for rotating and advancing the auger 1 in the ground.
  • a front part of a drilling auger 1 is shown, this front part being shown in two perspectives.
  • a side view of the part of the auger 1 is shown, which is rotatable about a longitudinal direction 2 of the auger 1.
  • this front part of the auger 1 is shown in a bottom view.
  • the auger 1 has two spirals 3 extending in the longitudinal direction 2 of the auger 1 and cutting tools 4 for milling and / or cutting and / or cutting the substrate.
  • cutting tools 4 are arranged in sections on an outer edge 5 of the filaments 3.
  • the cutting tools 4 arranged along the outer edges 5 of the helixes 3 allow a uniform milling, cutting or cutting of a substrate or a primary pile in the production of a secondary pile of a secant bored pile wall.
  • a guide element 6 is arranged at the front or lower end of the part of the auger 1.
  • the guide element 6 also has cutting tools 4.
  • a double-edged cutting bar 7 is formed in each case.
  • the cutting strips 7 are formed along a predeterminable portion of a diameter of the auger 1 to the outer edge of the diameter.
  • the outer ends of the cutting bars 7 thus extend substantially to the outer edge 5 of the helices 3.
  • These cutting bars 7 a guide function when introducing the auger 1 is realized in the ground.
  • the cutting bars 7 extend from an inner region of the auger 1 formed substantially through the conduit for the concrete to the outer edge 5 of the helixes 3.
  • a coupling region for coupling one or further sections of the auger 1 is formed.
  • Fig. 2 shows a part of a drilling auger 1 according to a second embodiment of the device according to the invention. It corresponds Fig. 2 in their construction the Fig. 1 , wherein in this second embodiment, only the coils 3 and the cutting strips 7 differ from the first embodiment.
  • FIG. 2 the second embodiment in a side view and in a bottom view.
  • the two coils 3 are formed in a front portion having a gradually decreasing diameter along a portion of the diameter.
  • the coils 3 run towards the front end of the auger 1 - along a longitudinal section of the auger 1 - tapered or tapered or conical. This has the consequence that the cutting strips 7 at the front ends of the helixes 3 do not extend to the outer edge of the diameter of the auger 1, but are formed shorter.
  • the width of the auger 1 in the region of the cutting strips 7 correspond to the distance between two primary piles, so that through the front end of the auger 1 or the coils 3 reaches a guide of the auger 1 between the primary piles becomes.
  • the cutting strips 7 would only work on the area of the substrate present between adjacent primary piles and no longer on the primary piles themselves, as is the case in FIG Fig. 1 the embodiment shown would be the case.
  • the size of the diameter of the auger 1 increasing from the cutting strips 7 along the helixes 3 up to the in Fig. 2 shown rear portion of the front part of the auger 1 allows a particularly safe and continuously deeper cutting in primary piles when introducing the auger 1 in the ground.
  • the concrete material to be removed on the primary piles is continuously removed or milled off or sheared off by turning the drilling screw 1 - virtually to the top.
  • Fig. 3 shows a schematic representation of a part of a secant bored pile wall 8 during their production. After the introduction of primary piles 9, the secondary piles 10 are introduced between juxtaposed primary piles 9 with overcut. At the in Fig. 3 shown bored pile wall 8 of the secondary post 10 shown on the left in the figure is not formed to the upper edge 11 of the bored pile wall 8.
