About this file

These technical drawings are detailed engineering specifications for seal modifications for the Tennessee Valley Authority's Main Lock Lower Gate and Upper Gate, Wilson Project. The documents provide comprehensive design details for water-tight rubber seals, including precise dimensional drawings, material specifications, and assembly instructions. Key technical requirements include using natural rubber or synthetic polyisoprene seals with specific material properties: minimum tensile strength of 2500 lb/in², elongation at break of 400%, and Shore Type A durometer hardness between 60-70. The rubber seals must maintain at least 80% of their original strength after accelerated aging testing, and must be certified by a rubber technologist documenting the material's actual properties and compounding details.

The drawings include multiple detailed views and cross-sections for lower and upper gate seal modifications, specifying mounting hardware (bolts, washers), drilling specifications, compression requirements, and installation guidelines. Each seal assembly involves complex curved and angled components designed to provide a precise, water-tight fit around gate structures. The technical specifications are extremely precise, with multiple reference drawings showing exact measurements, hole placements, material grades (primarily ASTM A36 steel), and detailed assembly instructions for field installation and fitting.
