Hamburg shoring

The Hamburg sheeting (also curtain walling ) is a special form of a pile wall . According to DIN 4124, it is a possibility of building pit shoring, which prevents the ground from sliding down into a pit . Related to the Hamburg lining are the Berlin lining and the Essen lining .

The name is derived from the first use in Hamburg. This is a pile wall with pile fasteners.

Manufacturing process and design training

The basic principle of producing pile walls is always identical and is described there. The Hamburg shoring is structurally characterized by the following training:

  • As with the Berlin sheeting, HEB or IPE shaped steel girders are usually used as vertical girders .
  • The excavation limit is the air side of the beam flanges. There is no need for time-consuming reworking by hand, as is necessary with the Berlin or Essen shoring.
  • Hook plates are pushed over the girders, over which a plank (more rarely squared timber) is fixed by means of wedges.
  • The anchoring back with ground anchors is comparable to the Berlin shoring. The space for the straps can be left out.

Advantages and disadvantages of the Hamburg shoring

The depth of the shoring is limited due to the limitation of the beam sizes and the thickness of the planks. This is why the Hamburg sheeting is preferred for construction pits up to 5 m deep. Construction pits of any geometry can be created. The beam flanges should, however, lie exactly in one plane because of the continuous planking. The beams and planks can be used multiple times. The Hamburg sheeting is a good alternative to sewer shoring devices and is therefore particularly common in sewer construction. Compared to the Berlin or Essen shoring, the work involved in the shaft is lower.
