Final answer:
Wooden or steel piles are indeed used in soft soil conditions to support pipe installations. Piles provide the necessary support when the soil lacks sufficient bearing capacity, ensuring the stability and integrity of the piping system.
Option A True is correct.
Step-by-step explanation:
The statement that wooden or steel piles may be required where the pipe is laid in very soft soil or fill is true. When laying pipes, the soil's bearing capacity is a crucial consideration. If the soil is too soft, it may not be able to support the weight of the pipe or the material flowing through it. In such cases, piles, which are long, slender columns made of wood or steel, can be driven deep into the ground to reach a layer of soil that is strong enough to support the structure. This technique ensures that the pipe remains stable and is not subject to excessive settlement or movement that could damage the pipe. While this is a common practice, the exact requirements for using piles depend on factors like the pipe material, the environmental conditions, and the engineering design specifications.
