What is the primary function of stringers or walers in shoring systems?

The primary function of stringers or walers in shoring systems is to distribute loads. In the context of construction and excavation, shoring systems are employed to support vertical excavation walls and prevent soil collapse. Stringers and walers serve as horizontal supports that help evenly distribute the loads imposed by the surrounding soil, equipment, and any additional forces acting upon the excavation site.

By distributing these loads effectively, stringers and walers help maintain the structural integrity of the shoring system, ensuring it can safely hold up the excavated area without failure. This is crucial for protecting both the workers in the excavation and the surrounding environment from the potential dangers of soil collapse. Other functions such as providing ventilation or assisting in drainage are not the primary concern of walers or stringers in a shoring application, which further emphasizes their role in load distribution.
