Definitions

  • the invention relates to a Rammspitze for a substantially tubular, in particular hollow cylindrical, driven pile with a pile core through which concrete can be introduced into the pile, the ram tip is attachable to a pile end of the pile, wherein on an inner wall of the Rammspitze at least a first bearing web a first bearing surface is arranged for an end face of the pile end.
  • Such Rammspitzen are used in the construction industry for the production of pile foundations.
  • the individual piles which are usually made of ductile cast iron and have predetermined lengths of, for example, five meters, are plugged into each other to produce a pile foundation.
  • the piles In order to facilitate the nesting of piles and thus the extension of a pile foundation, the piles usually have a conically tapered first pile end and a second pile end formed into a sleeve.
  • pile by pile can be driven into the ground, which can be produced quickly and inexpensively pile foundations of any length.
  • Piles of this type are usually produced in a centrifugal casting process with a shaping rotating mold. This results in substantially cylindrical tubular piles, which are hollow inside. Depending on the type of use, these hollow cylindrical ramming piles can be filled or encased with concrete or another suitable grout after being grounded to produce a stable foundation.
  • a ram tip is slipped onto the first driven pile, whose outer diameter is larger than the outer diameter of the driven pile.
  • an annular space can be generated during ramming, which can be filled up by a compression with the injection material or concrete.
  • a pumpable concrete mortar which usually has a grain size of up to 4 mm, is conveyed through the hollow pile core of the driven pile to the pile base and pressed into the ground at the ramming point.
  • the concrete grouting takes place simultaneously with the pile pile and is completed upon reaching the final depth of the pile foundation.
  • the object of the invention is to provide an improved Rammspitze can be made with the pile foundations while avoiding the disadvantages described above.
  • the ram point can be plugged onto a pile end of the pile pile.
  • concrete mortar or another suitable injection material can be introduced into the annular space between the outer diameter of the ramming tip and the outer diameter of the driven pile during ramming, without corresponding cuts or openings having to be made in the jacket of the driven pile.
  • the Rammpfahl need not be manipulated when using a Rammspitze according to the invention, whereby no unwanted weakening of the pipe cross-section of the driven pile takes place.
  • the ram point at least partially, preferably completely, made of cast iron and has a substantially rotationally symmetrical outer shape, wherein the axis of rotation extends substantially in Einrammraum. If an outer diameter of the ram tip in the driving direction substantially continuously reduced, a pile foundation with the use of a proposed Rammrade can be particularly easily rammed. Of course, however, it can also be provided that the outside diameter of the ram tip is essentially constant along its extension in the direction of insertion.
  • the at least one first support web is formed in cross-section to the Einrammutter as a circular segment or annulus segment. It is advantageous if a circular arc of the circular segment or annulus segment extends over less than 340 °, preferably over 40 ° to 120 °, more preferably over 70 ° to 90 °.
  • a plurality of concrete outlet channels preferably three concrete outlet channels, is or are provided.
  • two concrete outlet channels of the plurality of concrete outlet channels are arranged in cross section to the Einrammcardi along the inner wall of the Rammspitze substantially equidistant to each other.
  • the concrete outlet channels can also be arranged along the inner wall of the Rammspitze that they have irregular distances from one another.
  • At least one radially inwardly projecting supporting device may be provided on the inner wall.
  • the at least one radially inwardly projecting support device may be formed as a plurality of support ribs.
  • At the Rammrade at least a second support web is arranged with a second bearing surface for an end face of a pile end, in Einrammcardi the distance of the second bearing surface from the edge of the ram tip is greater than the distance of the first bearing surface from the edge of the ram tip.
  • the first and second bearing surfaces lie in the same plane.
  • the first and second bearing surfaces can preferably lie in a plane parallel to a cross-sectional plane transversely to the direction of insertion E.
  • Fig. 1 a shows a longitudinal section of a proposed Rammspitze 1 along a Einrammutter E and Fig. 1b shows a cross section along section line AA.
  • the Rammspitze 1 is made in one piece in this example and is made of ductile cast iron.
  • the outer shape of the Rammspitze 1 is rotationally symmetrical with respect to the rotation axis R formed.
  • the Rammspitze 1 has an outer diameter D which is greater than an outer diameter D P of a pinned Rammpfahls 2.
  • the outer diameter D of Rammspitze 1 decreases in the direction of its end truncated cone, whereby the ramming of a pile foundation with plugged Rammrade 1 is facilitated.
  • the first bearing surfaces 7 of the first support webs 6 lie in one plane and form a defined stop for the end face 8 of a pile end 4 of a pinned Rammpfahls 2.
  • the driven pile 2 in Einrammutter E so far attached to the Rammrade 1 be until the end face 8 of the pile pile 2 rests against the first bearing surfaces 7 of the first support webs 6.
  • the maximum insertion depth of the driven pile 2 in Einrammutter E results from the distance T from the upper edge 11 of the Rammrade 1 to the plane of the first bearing surfaces. 7
  • a cavity 9 is formed in the Rammspitze 1, which extends in Einrammcardi E. Between the cavity 9 and the upper edge 11 of the Rammrade 1 three concrete outlet channels 10 are formed in this example. This makes it possible that in the production of a pile foundation concrete mortar, which is introduced through the pile core 3 of the driven pile 2 and penetrates via the end face 8 in the cavity 9, passes through the concrete outlet channels 10 to the outer wall of the driven pile 2 and thus the production of a Mantelverpressung allows.
  • Fig. 1b shows the Rammrade 1 the Fig. 1 a in a cross-sectional view along section line AA of Fig. 1 a.
  • the stop arranged at a distance T from the upper edge 11 of the ramming tip 1 in the direction of insertion E for the end face 8 of the driven pile 2 is formed by a total of three first bearing surfaces 7.
  • Each of the three first support webs 6 is formed in cross section to the Einrammcardi E as a circular ring segment.
  • the circular arc 12 of each circular segment extends in each case over a diaper area of 80 ° and the three circular arcs 12 are arranged distributed uniformly along an imaginary circle.
  • each concrete outlet channel 10 is arranged between each two first support webs 6, a concrete outlet channel 10 is arranged.
  • two concrete outlet channels 10 along the inner wall 5 of the Rammspitze 1 are arranged substantially at equal distances from each other.
  • each concrete outlet channel 10 extends over a Angular range of 40 °.
  • a plurality of support ribs are arranged as supporting devices 13 on the 5.
  • Fig. 2a shows a possible development of a Rammspitze 1 according to Fig. 1 a.
  • this embodiment additionally has second support webs 6 'for a second driven pile 2' with a different outer diameter D P 'relative to the driven pile 2.
  • Each second support web 6 ' has a second bearing surface 7', wherein the sum of the second bearing surfaces 7 'forms a defined stop for the end face 8' of the second driven pile 2 '.
  • the distance T 'of the second bearing surfaces 7' from the edge 11 of Rammspitze 1 is greater than the distance T of the first bearing surfaces 7 from the edge 11 of Rammrade 1.
  • both bearing surfaces 7, 7 'in the same Lie flat In this case, only the width of a bearing surface 7, 7 'in the radial direction would need to be chosen so large that it is suitable for the entire bandwidth of the outer diameter D P , D P ' of the driven piles 2, 2 'to be used.
  • Fig. 2b shows the Rammrade 1 the Fig. 2a in a cross-sectional view along section line AA. It can be seen that the bearing surfaces 7, 7 'corresponding to the different outer diameter D P , D P ' of the driven piles 2, 2 'have a different radial distance from the axis of rotation R of the Rammspitze 1.
  • the structural design of the Rammspitze 1 shown, however, is otherwise similar to the Rammrade 1 of Fig. 1 b.
