About this file
This is a technical drawing sheet for pipe culvert headwall details prepared by the U.S. Army Corps of Engineers Tulsa District for a construction project at Tinker Air Force Base in Oklahoma City. The document, designated as Sheet CU510, is part of the KC-46A Depot Maintenance Complex Support Infrastructure project under Contract No. W912BV-16-C-0029 and was completed as an as-built drawing in May 2016.
The drawing provides detailed specifications for reinforced concrete headwall construction including plan views, elevations, and cross-sectional details for typical wingwall sections and storm drain pipe end sections. Key technical requirements include reinforcing steel with a yield strength of 60 KSI; galvanized structural grade steel bars and angles with 2.0 ounces of zinc per square foot; stainless steel bolts; and 5/8-inch diameter expansion anchors with 4-inch minimum embedment spaced at maximum 2-foot centers. The document specifies variable dimensions for different pipe diameters (18 inches to 42 inches and greater), detailed bar placement patterns with specific spacing requirements, weld specifications, and manproofing details requiring inspection and approval by the Contracting Officer. The drawing cross-references rip rap protection details for flared end sections on another sheet (CU509) and includes a comprehensive table of variable dimensions correlating to specific pipe sizes and structural reinforcement requirements.
