Question

An excavation is at risk for cave-in and water accumulation because of the excess soil that has accumulated. what type of excavation protection will address this situation? select the best option. water accumulation correctly placed spoils oxygen deficiency and toxic fumes

Answer 1

The best type of excavation protection to address risks of cave-in and water accumulation in an excavation is shoring and dewatering.

Step-by-step explanation:

To address the risks of cave-in and water accumulation in an excavation due to excess soil, the best type of excavation protection is shoring and dewatering.

Shoring involves using supports or braces to prevent the collapse of soil or rock walls in an excavation. This helps to stabilize the excavation and minimize the risk of a cave-in.

Dewatering, on the other hand, involves removing or controlling the water in the excavation. This can be done through methods such as pumping, draining, or using water control structures. By reducing the water accumulation, the risk of flooding and related problems is minimized.

Answer 2

To address the risks of cave-in and water accumulation in an excavation due to excess soil buildup, the most appropriate excavation protection method would involve correctly managing the spoils and preventing water accumulation. Option A

By properly managing the spoils (excess soil), ensuring they are placed in a manner that does not create additional hazards or increase the risk of collapse, and implementing measures to prevent water accumulation within the excavation, such as proper drainage systems or pumps, the risks associated with cave-ins and water accumulation can be effectively mitigated.

Therefore, the best option to address this situation is: correctly placed spoils.
