Description

"Anchoring pile" the invention relates to an anchoring pile or an excavation pile.

It is known to have foundation piles with concrete jacketing in the way manufactureii that a pile with a displacement shoe at the tip-e, in particular of larger cross-section, is used. These driven piles are called $ MV driven pile "in use.

The when ramming through the displacer P-pole shoe, in particular the larger pile shoe, the space created is then filled with cement slurry, Its bond with the ground provides excellent anchoring and stability of the foundation pile results. Such Foundation piles can use both Absorb compressive and tensile forces.

There are also anchoring piles known in which a displacement shoe has the cross-section of the ram pipe. In the cavity of the ram pipe is after At the end of the ramming, a tie rod was inserted and screwed to the pile shoe. If the anchoring post is longer in a non-horizontal iae, this is the introduction extremely difficult, both because of the length and also because of the attachment with the driven pole shoe.

The invention now aims at the formation of these anchoring piles while avoiding the aforementioned disadvantages: An anchoring post with an opposite preferably an enlarged pile shoe on the ram shaft. the top in which the tie rod running to the end of the pile is used, is therefore in the way designed that the anchor rod from partial lengths, preferably in adaptation to the Ramming pipe sections, can be assembled.

The first section is connected to the tip of the pile and this part is then rammed in and at the same time grouted with cement mortar. It will then another Telstück attached and again wrapped and pressed. Afterward the process is repeated until the required driving depth is reached.

The advantage of the anchoring pile shown is that. that respectively the fastening of the sections to one another or of the first section can be carried out freely accessible in the pile shoe before ramming. Through this is above all a safe and controllable connection of the anchoring parts can be carried out with one another or with the pole shoe.

The special design of the pile and the resulting The procedure also not only enables anchoring piles to be introduced in the horizontal or downward direction, but also upward, i.e. that is, in any direction. Needs for an upward pile-driving thus not an additional reinforcement slot for the entire length of the anchor to be present.

Another advantage is that the pressing or Do not fill with cement slurry later, but at the same time as the ramming process can be executed. This results in connection with the displacement neck shoe as it was found, better adhesion of the anchoring pile in the ground.

On the basis of the following drawing, the subject of the burnishing should be be explained in more detail scr-ematically.

Fig. 1 shows an anchoring post (3) with the sections (5 T 8) of the tie rod.

Fig. 2 shows schematically an almost completely inserted anchoring pile.

In the figures, 1 is the pole shoe, in which threaded 2 a section 3 of the tension rod can be used on the wall to be secured. am «nde of the part sits a threaded part 4, into which the second part 5 can be attached is. Just like the section 8, the parts 7 and 9 can be connected. 10 is the end threaded part for anchoring the end to the wall to be secured.

in Fig. 2 it is still that from the sections 12, 13 and 14 composite ram pipe indicated, which by the larger diameter of the rfahlschuhes 1 has created the well-being space 11 in the ground. The ram pipe sections can be pulled out again after ramming and grouting before the grout hardens and reused, with only the pile tip and anchor rod in the Soil remain.

Claims (3)

Expectations 1. Anchoring pile with a shank opposite the pile preferably enlarged pole shoe at the top, in which one runs to the end of the pipe Anchoring rod is used, characterized in that the anchor rod is made of Part lengths can preferably be put together in adaptation to the ram pipe sections. 2.) Method for introducing the anchoring pile according to claim 1, characterized in that a section of the anchoring rod with the displacement shoe rammed in and each by extension pieces for further complete ramming is provided. 3.) Anchoring post according to claim 1, d a d u r c h g e k e n n-æ e to b h n e t t that the Rammroghr sections after Ranunung and grouting can be withdrawn and reused before the grout hardens can.
