In contiguous pile walls, the axial distance of piles is bigger than their diameter. The space between them is usually filled with shotcrete and reinforcing mesh. This space must be correctly drained, so that rainwater does not stay behind the concrete. The drainage is usually made of perfored plastic tubes. These drains divert the water downward, towards the front of the shotcrete.
Programs provide different types of soil anchors. Pre-stressed bar anchors (VSL, Dywidag), strand anchors (VSL, Dywidag), helical anchors (Helical Anchors Ltd, Chance, MacLean), anchor bars (VSL, Minova), deadman anchors. Parameters of anchors are included in database, which is a part of programs.
