Trenching is a method used in construction and excavation to create narrow, deep ditches in the ground. This technique is essential for installing utilities such as water pipes, sewer lines, and electrical cables. Proper trenching ensures that these installations are safe and effective, minimizing the risk of damage or disruption. Safety is a critical aspect of trenching, as the walls of the trench can collapse if not properly supported. Workers must follow strict guidelines and use equipment like shoring to prevent accidents. Understanding trenching techniques is vital for any construction project involving underground installations.
