In trench safety, which method is used to keep trench walls stable?

• A. Hydraulic shoring
• B. Wooden shoring
• C. Steel plates
• D. Bracing

Answer: (A)

The main idea here is how trench walls are kept from collapsing while work is done. Hydraulic shoring uses hydraulic cylinders placed between shores to push against the trench walls, creating controlled, adjustable lateral pressure that holds the soil in place. This system can be set and adjusted quickly as the trench depth or soil conditions change, providing continuous support and reducing the risk of a cave-in as workers perform tasks inside the trench. While wooden shoring, steel plates, and bracing are also used in some setups, hydraulic shoring offers rapid installation and easy adjustment, making it a preferred method for keeping trench walls stable.
