Definitions

  • the invention relates to a method for determining the carrying behavior of displacement piles, which by introducing a borehole by means of a displacer head and then Fill the borehole with a hardenable suspension made while leaving the displacer head downhole be created, with a test pile and by means of a Loading device subjected to a test load is measured and by means of a measuring device, the bearing behavior becomes.
  • the invention further relates to a test arrangement for determining the carrying behavior of displacement piles.
  • test piles can then be subjected to a predetermined test load become, whereby then the appropriate carrying behavior, in particular a settlement of the pile, can measure.
  • the test pile by means of a load device applied, which a predetermined pressure on the test pile exercises.
  • a load device applied, which a predetermined pressure on the test pile exercises.
  • the invention has for its object to provide a method and a test arrangement for determining the carrying behavior of displacement piles made of concrete with a displacer, with which the bearing behavior of these displacement piles can be determined particularly quickly and economically.
  • the method according to the invention is characterized that the displacer head into the ground by means of a metallic Stakes is introduced, which together with the Displacer forms the test pile.
  • the invention is based on the finding that positive displacement piles with a so-called lost displacer the Trag decisively determined by the displacer becomes.
  • the displacer head becomes instantaneous introduced through a pile strand in the ground, which together forms the test pile with the displacer head.
  • the pile strand is so in its diameter and in its length to the actually provided displacement pile from the hardened Suspension, in particular concrete, adjusted.
  • the displacer head Can be made of metal, concrete or another suitable Material exist.
  • test load immediately after the Inserting the pile strand with the displacer head into the ground respectively. This saves time and money.
  • a particularly accurate determination of the Trag s be achieved by that of the measuring equipment determined values for the metallic test pile by means of a correction factor according to the properties the displacement piles converted from the hardened suspension become.
  • a Lastverteilkopf is arranged, which the Test load transfers to the pile string.
  • the pile string At its top End of the pile strand may have a connecting device, with which the load head or a press device can be easily attached.
  • a preferred development for this is that at least two anchor elements around the test pile around in the ground are introduced and that the Lastverteilkopf with the anchor elements connected to the power dissipation.
  • the anchor elements can be in particular screw anchors, which in the necessary Number at a certain angle to the test pile in be screwed in the floor. The load distribution head will then clamped with the screw anchors, giving a compressive force the test stake can be exercised.
  • a press device is arranged, through which the test load is produced.
  • the press can in particular be a hydraulic pressure cylinder which, when moving apart between the Lastverteilkopf and the test pile the desired Compressive force generated.
  • the displacer head remains in the ground and when removing the pile strand, the hardenable suspension is initiated.
  • the pile strand is detachable with the Displacer coupled, such as by a thread.
  • the test stake can in the test in a simple manner in be converted to a building carrying displacement.
  • the test pile can be placed directly at the location of a carrying pile.
  • the test pole with the metallic Pile string immediately remains in the ground and together with the other to be created displacement piles of concrete the Building carries.
  • the pile strand is a cylindrical element, in particular a pipe is the outer surface for increasing a Friction factor is changed with the soil.
  • a Friction factor can be roughened or with the outer surface of the pile strand Profile elements, be provided about helical.
  • the friction factor can be an empirical friction factor between be adapted to a concrete pile and the ground.
  • the invention further relates to a test arrangement for Determining the bearing behavior of a displacement pile with a Displacement head, comprising a loading device for Apply a test load.
  • the test arrangement according to the invention is characterized in that a metallic drill string is provided, at the lower end of a displacer and at the upper end of the loading device releasably secured is. With this test arrangement, in particular the before described method and the associated Benefits are achieved.
  • the measuring device can in the Pile strand or integrated into the load device. Alternatively, a mobile measuring device can be connected separately become.
  • the invention is based on a preferred embodiment further described, which is schematically in the drawing is shown.
  • the only figure shows one schematic side view of a test arrangement for determining the structural behavior of displacement piles.
  • a test pile was made 30 in the area shown with a ground area Displacer 32 driven, which the soil in the displaced surrounding soil area.
  • the test pile 30 points beside the displacer 32, a metallic pile strand 34th on, which via a connecting device 36 releasably with the displacer 32 is connected.
  • the test pile 30 corresponds in terms of its length and its diameter actual displacement piles made of concrete become.
  • a load device 12 is placed on the test pile 30 with a load distribution head 14 and a hydraulic press device 18 arranged.
  • the Lastverteilkopf with screwed laterally at a predetermined angle Anchor elements 16 coupled.
  • the press device 18 is a predetermined test load on the test pile 30 exercised.
  • the Trag in particular the setting of the test pile 30, measured.
  • the settlement behavior of the test pile 30 with the metallic pile strand with surprisingly high accuracy the settlement behavior of a Concrete displacement pile.
  • the friction value of the metallic pile string 34 to a concrete column can, for example, formed as helical profile elements 38 may be formed along the pile string 34.
  • the tubular pile strand 34 from the displacer head 32 approximately by opposite rotation be released and withdrawn from the Bohr.
  • the resulting cavity with a hardenable suspension, in particular concrete are filled.
  • the metallic test pile can be easily inserted into a concrete pile to be reworked, which then to the building foundation can be used.
