Systems and methods for removal of trunnion pin sleeve and for supporting tainter gate during said removal

摘要

Methods and systems for use in the removal of trunnion pin sleeves and the supporting of lock and/or dam gate structures (e.g., tainter or roller gates) are disclosed herein. In one example embodiment, a method of trunnion pin sleeve removal includes causing either a constriction of at least one part of the sleeve or an application of a torque with respect to the at least one part of the sleeve, and subsequently applying a force to the at least one part of the sleeve so as to pull out the sleeve. Also, in another example embodiment, a system for supporting a lock and/or dam gate assembly includes a support assembly having a at least one pedestal assembly. The support assembly further includes a trunnion arm support structure, configured to be supported at least in part by the at least one pedestal assembly and to at least partially support a trunnion arm.

主权项

1. A support assembly comprising:
at least one pedestal assembly; and a trunnion arm support structure, configured to be supported at least in part by the at least one pedestal assembly and to at least partially support a trunnion arm of a lock and/or dam gate assembly; wherein the at least one pedestal assembly includes a beam or beam-like structure and a plate or plate-like structure configured for connection to a respective beam and to rigidly secure the pedestal assembly to a pier or similar structure; and wherein the at least one pedestal assembly includes a cantilevered portion that is configured to extend over an edge of the pier or similar structure and receive, so as to support, a portion of the trunnion arm support structure.
