Standards and regulations
Sheet pile walls are designed and manufactured in accordance with DIN EN 1054 and the recommendations of the “Construction Pits” Working Group (Empfehlungen des Arbeitskreises "Baugruben", EAB).
The sheet piles are vibro-compacted into the ground with frame leaded high-frequency vibrators. A range of steel profiles are available for this purpose. The individual sheet piles are friction-locked together by interlocks and form a continuous wall. Sealing tapes, bitumen grouting and additional welding can be used to achieve a very high degree of watertightness.
If the neighbouring buildings are particularly vulnerable, sheet piles can also be gently inserted into the ground using hydraulic jacks. If there are no requirements for noise or vibrations, especially heavy profiles can be installed quickly and economically using the corresponding pile drivers.
From a certain excavation depth, the sheet pile wall must be secured to prevent severe deformation. This is done by installing chording on the side facing the construction pit, which is then tied back into the soil with grouted anchors. If anchors cannot be used, the chording can also be shored on the inside.
