Trench shields are engineering structures used to prevent cave-ins during excavation work.

Step-by-step explanation:

Trench shields are an engineering solution designed to prevent cave-ins during excavation work. They are large, sturdy structures made of metal or other materials that are placed around the sides of a trench to provide support and prevent the soil from collapsing inwards.
