Pipe sheet pile wall

Description
5

The innovation concerns a pipe sheet pile wall, consisting of supporting pipes arranged one behind the other with sheet pile piles arranged in between.

The innovation is applicable wherever mixed sheet pile walls consisting of supporting tubes or double-T-shaped supporting piles of the Peine type with filling piles arranged in between are used.

Mixed sheet pile walls of various types are known to the expert.

Which sheet pile wall is used depends, among other things, on which system is available from which manufacturer. A combination of different systems from different manufacturers is generally not carried out, since the connecting parts of the different systems do not fit together.

From GM 76 30 402 U1, z-shaped sheet piles are known, in particular for the combination of combined sheet pile systems, with which chambers can also be produced, from which the sheet pile can be further constructed with different double and z-shaped sheet pile elements.

Suggestions for combining these elements with tubular elements cannot be found in this document.

DE 42 05 455 C1 describes a double-walled sealing wall made of sheet pile profiles, in which sheet pile elements of the Peiner type

:i 2 :: :::« 2290GM

Chambers can be produced that can be joined together to form a tight sheet pile wall. The use of tubular elements with this sheet pile wall is not obvious to the expert.

DE US 28 19 737 discloses sheet piles that can be joined together using Peiner lock steel, whereby chambers are formed using z-shaped profiles, although this publication also does not contain any tubular sheet pile elements.

&iacgr;&ogr; Tubular sheet pile elements are manufactured as so-called steel ramming pipes and initially do not have any connecting elements for further sheet pile elements or connecting elements.

Already known tubular sheet pile elements, to which connecting elements for further sheet pile elements are subsequently attached, have the disadvantage that these tubular sheet pile elements must be placed very precisely in the ground, since the complexity of the existing lock means that there is only a very low joint effect of the parts to be connected.

Pipe sheet pile walls have the advantage that obstacles can be broken up, crushed and removed when ramming or shaking the tubular element in the ground by emptying the supporting pipe. After that, the installation can be continued up to the intended final depth. This option is not available with sheet pile walls with supporting piles of the Peine type.

The aim of the innovation is therefore to develop a pipe sheet pile wall in which supporting pipes are connected to intermediate piles, whereby the connection between pipes and intermediate piles is designed with the greatest possible joint effect.

is equipped and the intermediate planks as statically determined load-bearing systems can absorb high direct loads.

This problem is solved according to the characterizing features of the first patent claim.

The subclaims reflect advantageous embodiments of the invention.

The innovation provides that a pipe sheet pile wall, consisting of supporting pipes arranged one behind the other with sheet pile filling piles arranged in between, is designed in such a way that a Peiner interlock steel is arranged as a connecting element between the supporting pipes and the individual sheet pile wall elements. By arranging a Peiner interlock steel, the connected part can be twisted by up to ± 15° depending on the rolling tolerance.

In order to be able to connect a Peiner lock steel to a pipe, an alternative option is to use a docked supporting pile flange, i.e. only its lobe section, to be firmly connected to the pipe of the pipe sheet pile wall, for example by welding. This can be done in the pipe axis, but also outside the axis on the pipe circumference.

If the lobe sections are not arranged in the pipe axis, support plates or angle profiles can be welded to the pipe, to which the lobe sections are attached. Peiner interlock steels can then be pulled onto the lobe sections, into which sheet pile elements, for example Z-shaped sheet pile elements, can be pulled, which in turn are connected to one another by Peiner interlock steel.

The innovation has the advantage that pipe sheet pile walls can be made from pipes with Peiner intermediate elements, coupled using Peiner lock steel, whereby a greater joint effect is achieved between the parts to be connected. The innovation will be explained below using an example and 4 figures.

connected pipes

Figure 1 shows two mixed pipe sheet pile walls made of supporting pipes and Peiner intermediate piles, whereby in the left pipe sheet pile wall three pipe elements 1 are connected to each other with two intermediate piles 3 each. The intermediate piles 3 are arranged on the water side 9, i.e. above the pipe axis 6. The right-hand illustration of Figure 1 shows three pipes 1 of a pipe sheet pile wall, between which intermediate piles 3 are curved inwards, i.e. on the other side of the pipe axis 6, i.e. the side facing away from the water side 9. The detail Z from Figure 1 can be seen in Figure 2. With the pipe 1 of the sheet pile wall, a Peiner lock steel 2 was welded directly to the pipe 1 in the pipe axis 6.

so that an intermediate plank 3 can be connected directly. Shown is the beginning of a Z-shaped intermediate plank. If necessary, other intermediate planks with a club-shaped end section can also be inserted into the Peiner lock.

Figure 3 shows the pipe 1 of a pipe sheet pile wall, to which a docked Pein support pile flange (lobe section) 5 has been welded in the pipe axis 6, onto which a Pein interlock steel 2 has been pulled, which is connected to an intermediate pile 3. The intermediate pile 3 is, as already shown in Figure 1

“ shown, can be attached in different directions between the Peiner steel interlocks. If it is necessary to arrange the intermediate planks 3 outside the pipe axis 6, this can be done with the help of support plates 7 and angle profiles 8, as shown in Figure 4. In the representation of Figure 4, the Peiner interlock steels 2 are pulled onto flange sections with support plates 7 or with angle profiles 8 in order to create a connection between the support pipes 1 and the intermediate planks 3. Also possible and not shown in Figure 4 is welding the Peiner interlock steels 2 to the angle profile 8 or the pipe 1 outside the pipe axis 6 or a combination of the above options.
