Abstract

The new Folsom Dam Auxiliary Spillway gated Control Structure, part of the overarching Joint Federal Project, was recently completed. To make operation and maintenance activities for this activity more user-friendly, this project implemented innovative designs, and a select few related to the tainter gate (seals, dogging system, and anchor inspection access) are presented in this paper. This project also provided additional monitoring capacity to the trunnion anchors, both during and post-construction, both physical and data, with great results. Further, this paper discusses some lessons learned on tainter gate specifications during gate construction and installation. Building and bridge construction specifications were generally used in project specifications; however, there are components on the tainter gate that require special attention, such as ASME tolerances and high strength bolting in connections with multiple thick plies. Additionally, this paper also suggests specification language and practices to better meet the design intent in terms of fabrication and construction tolerances.

Folsom Dam Auxiliary Spillway – Design Innovations and Construction Lessons Learned

Portland, OR

The new Folsom Dam Auxiliary Spillway gated Control Structure, part of the overarching Joint Federal Project, was recently completed. To make operation and maintenance activities for this activity more user-friendly, this project implemented innovative designs, and a select few related to the tainter gate (seals, dogging system, and anchor inspection access) are presented in this paper. This project also provided additional monitoring capacity to the trunnion anchors, both during and post-construction, both physical and data, with great results. Further, this paper discusses some lessons learned on tainter gate specifications during gate construction and installation. Building and bridge construction specifications were generally used in project specifications; however, there are components on the tainter gate that require special attention, such as ASME tolerances and high strength bolting in connections with multiple thick plies. Additionally, this paper also suggests specification language and practices to better meet the design intent in terms of fabrication and construction tolerances.
