Tainter Valve One Corner Seal.pdf

This is a technical drawing from the U.S. Army Corps of Engineers depicting lock and dam navigation structures, specifically detailed design specifications for the top seal components of a navigation lock located on the Columbia River in Oregon and Washington. The drawing is marked as RD (Record Drawing) number 44, dated from the original construction documentation.

The document presents multiple cross-sectional and elevation views illustrating the top seal details and keeper mechanisms for a lock system. Key design elements shown include partial plan views of the top seal (presented at half size), a partial elevation view of the top seal, cross-sectional views through the top seal, a half plan-top seal keeper (at 3'/64" scale), and side elevation views of the top seal keeper. The detailed sections indicate various structural components including concrete elements, steel reinforcement patterns, sealing mechanisms, and dimensional specifications throughout. The drawing references specific construction details such as the section through the top seal, sections numbered 3-3 and A-A, and multiple keeper configurations. This appears to be historical construction documentation for water resources infrastructure rather than a solicitation or contract opportunity document.
