This structural detail shows a pipe trench formed within a concrete foundation footing, featuring front and side elevation views. The assembly includes minimum six-inch clearances above and below the pipe outside diameter, a two-inch typical clearance between the sleeve and pipe, and eight-inch minimum dimensions from the pipe diameter to the trench edges. The trench profile indicates compacted backfill over tamped sand with a strict restriction against excavation below the specified line. The concrete footing accommodates varying dimensions while maintaining required spatial separation for utility penetrations.
