What is Pipeline Excavation and Backfill Guide about?
The document outlines the key layers involved in excavating and backfilling a pipeline trench, including the subsoil, backfill as the upper layer, essential surrounding layer, substrate bedding layer below the pipe, and preparatory work such as marking the trench route and removing trench soil before filling. The trench must be wide enough for the pipe diameter and depth of laying, with special protections for non-cohesive soils like sloped sides or shoring, and a gravel or sand bed under the pipe.
