1 itemsThe proposed pile wall uses two types of helical elements for shoring excavations. The source discusses constrained sites near property lines or existing structures, including sites with a high water table.
The method may be used in a variety of situations involving a deep excavation, including excavation projects in constrained sites, excavation projects that extend close to a property line, and/or excavation projects that are adjacent to an existing structure.
In addition, the method may be used in areas in which the water table is high, and is lower in cost relative to the use of traditional tangent or secant walls which are typically more expensive and require greater volumes of cement to complete.
