Final answer:
True, The decision to use sheeting with hydraulic shoring depending on the soil type is true, as different soil types dictate different shoring requirements for trench stability and worker safety.
Step-by-step explanation:
The decision whether to use sheeting with hydraulic shoring depends primarily on the soil type is true. The type of soil is a critical factor in determining the shoring method because different soil types have varying strengths and stability properties. For example, cohesive soils like clay may require different shoring techniques compared to granular soils such as sand. When dealing with trench excavations, the soil classification is crucial in selecting the proper shoring system to ensure the safety and stability of the trench. Hydraulic shoring is a commonly used system because of its adaptability and ease of installation. However, the use of sheeting alongside hydraulic shoring can provide additional support to the excavation walls, particularly in unstable or loose soil conditions to prevent cave-ins.
