Standards and regulations
Steel pipe piles are designed and manufactured in accordance with Eurocode 7 and DIN EN 12699 and the recommendations of the “Piles” working group (EA-Pfähle). The usual pipe diameters are 219mm, 356mm and 406mm. Loads and pipe diameters should be adapted to the prevailing soil conditions. We will be happy to advise you on this.
A starting pipe, which is closed at the base, is driven into the ground using inner pipe ramming. Extension pipes can be attached and welded in place around the circumference, if required, so that the workflow can continue. Once the final depth has been reached, the pipes are filled with concrete and the heads are reinforced to secure the connection.
The steel pipes remain in the ground in their entirety and act as additional protection against concrete aggressive water and soft strata. Excess piping is trimmed off after the required depth has been reached. The steel profile is capable of bearing the loads on its own.
Steel pipes are relatively lightweight, which means that the piles can be produced with a small, compact device. This allows the pile foundations to be produced in very confined and challenging spaces. The inner pipe ramming method allows the piles to be driven gently into the ground with virtually no vibrations, even in the immediate vicinity of existing buildings.
