Supporting panel walls
In addition to steel sheet piles supporting panel walls are frequently used in the groundwater-free area for excavation pits. Supporting walls consist of vertical support piles as steel beams or UU-beams. The supporting piles are installed vertically at a distance of up to 3.50 meters into the ground by hammering, vibrating or setting into pre-drilled holes. When setting into pre-drilled holes the support piles often receive a welded foot plate. The supporting piles generally have a length of 6 to 18 meters.
