What does the term "Uprights" refer to in timber shoring tables?

The term "Uprights" in the context of timber shoring tables specifically refers to the vertical sheet piles that are used to support and restrain the soil. These uprights play a critical role in maintaining the structural integrity of the shoring system by providing vertical support. They help to distribute the load of the soil and any applied forces, ensuring that the shoring remains stable and effective during excavation or construction activities.

In timber shoring, the design typically involves various components, and the uprights are specifically designed to counteract lateral soil pressures. This function is essential to prevent collapses or other failures that could endanger workers or surrounding structures.

Alternative choices refer to different components or configurations that do not accurately capture the defining characteristic of what uprights are. For example, horizontal supports would be more akin to cross-bracing elements, while the base of the framework would outline the foundational structure rather than the vertical support needed during excavation. The top brace may also be a support feature but does not fulfill the same role as the vertical uprights in providing direct resistance to soil pressure.
