Use of pipes – BERLIN WALL

The term “Berlin Wall” identifies a structure supporting the excavation front (also on high heights, more than 15/20 m.), formed by a series of micropiles with a vertical wheelbase, depending on diameter of the pipes used in the reinforcement: in particularly cases, micropiles can also be arranged in a staggered row.

However, the contrast against horizontal loads relies on ground anchors. This technique is particularly suitable in urban areas, where construction space is increasingly more restricted making the use of diaphragms or large diameter piles impossible. The limited size of equipment allows Berlin Walls also by existing buildings, fully exploiting the buildability of the area.

Besides all the advantages mentioned above, the Berlin Wall, compared to other supporting structures, is built with absence of vibrations, without bentonite, drilling muds or end products, avoiding any expensive and problematic disposal.
