The "Safety Wall (ASW) Method" is a vertical retaining wall construction method that utilizes piles and tie-back anchors, characterized by the absence of a base slab, which is essential for conventional vertical retaining walls. This allows for a smaller construction profile, minimizing the impact on the natural environment. It has already been certified by the Minister of Construction as a retaining wall that does not require a base slab (certified by the Japan Building Center and obtained "individual" certification from the Minister of Construction) and has patents for three types: back anchor type, bracket type, and pit type. 【Features】 - Since a base slab is not required, the amount of earthworks such as excavation and backfilling associated with construction is reduced. - The new structural form allows for the construction of retaining walls even in narrow sites where conventional methods are not feasible. - Reinforcement and repair of retaining walls at risk of collapse can be carried out with minimal impact on existing buildings. - By using H-beams for the supports and PC panels (factory-produced) for the wall body, construction time can be shortened. - It is also possible to use cast-in-place RC structures for the wall body, allowing for flexible adaptation to local conditions.

• Retaining wall

The Safety Wall Method (ASW Method) is a bracket-type or self-supporting vertical retaining wall method that maintains stability through the resistance of piles, supports, retaining walls, bracket plates, weight concrete, and other elements. It does not require a base slab like conventional RC retaining walls such as L-shaped walls, resulting in reduced excavation and backfill cross-sections, thus offering excellent economic efficiency and constructability.
