摘要
Abstract
As an important navigation structure in the Jialing River Basin,the Dongxiguan Ship Lock have been suffering from severe abrasion on their bottom hinge of the miter gates due to long-term exposure to alterna-ting heavy loads and friction.Therefore,the bottom hinge needs to be replaced.This paper addresses technical difficulties of replacing the bottom hinge from three aspects:the lifting scheme,the control of the reinstallation accuracy of the bottom hinge,and the disassembly and assembly technology.Based on the maintenance experi-ence of the Three Gorges and other ship locks,a construction plan combining a low-position synchronous lifting system with a precision measurement control network is proposed.The research shows that a rational lifting process and precise positioning technology are the core to ensuring the quality of the bottom hinge replace-ment.The results of this paper can provide technical references for the replacement of the bottom hinge of mi-ter gates in similar projects.关键词
