Trench shield
Trench shields (also called trench boxes or trench sheets) are
professional engineers.[clarification needed][citation needed
]
A shield should not be confused with a shore. While they may serve a similar function, trench shoring is a different physical application that holds up the walls of a trench to prevent collapse.[1]
In the US, use of a trench shield is governed by OSHA 29 CFR Part 1926.650-.652 Subpart P-Excavations.
