Why are trench boxes preferred over shoring in some situations?

Trench boxes are particularly favored in many excavation scenarios due to their ability to be installed quickly, which offers immediate protection for workers in the trench. This rapid installation is crucial, especially in environments where time is of the essence, such as when weather conditions can change or in emergency situations. Trench boxes create a safe working environment by providing lateral support for the walls of the trench almost as soon as they are in place, reducing the risk of collapse while workers are present.

This quick setup significantly enhances safety and productivity, allowing work to resume rapidly once the box is installed. Such advantages make trench boxes a practical choice compared to other methods, which may not offer the same level of immediate protection or efficiency.
