During excavation for underground pipe inspection, how should the pipe be excavated?

• A. All at once
• B. At practical intervals
• C. In random sections
• D. Only where visible

Answer: (B)

Excavating the pipe at practical intervals is a best practice because it allows for a controlled and systematic approach to inspection. By exposing the pipe in segments, the inspector can assess the condition of each section thoroughly while minimizing disturbance to the surrounding environment. This method not only aids in ensuring safety but also helps in identifying potential issues such as corrosion, leaks, or other forms of degradation more effectively. When pipes are excavated all at once, it can lead to complications such as soil instability or difficulties in managing the excavation safely. Random sections may miss critical areas that require inspection, and only excavating where visible could overlook hidden problems that could cause failure in the future. Thus, excavating at practical intervals strikes a balance between thoroughness and practicality in inspection efforts.
