八里湾船闸入湖口施工关键技术探讨与应用

Discussion and Application of Baliwan Navigation Lock Lake Entrance Construction Key Technology

京杭运河八里湾船闸工程是京杭运河续建工程济宁至泰安段的重要组成部分,是连接南四湖与东平湖航线的重要梯级船闸。八里湾船闸上游引航道与东平湖相连,湖口项目施工是该工程最后关键环节。在南水北调东线全线通水的情况下,针对湖口项目施工应如何减少对东平湖水质污染的问题,探讨出施工关键技术方案并应用,从而确保了工程效益和水质环境,并降低了工程造价。

The Grand Canal Baliwan Navigation Lock Project is an important part of the Grand Canal Extension Project from Jining to Tai＇ an, which belongs to important chain lock for connecting Nansi Lake to Dongping Lake routes. Upstream approach channel of Baliwan navigation lock is connected with Dongping Lake, and project construction aiming at lake entrance is the final key link in the project. Under the condition that east line whole-process water penetration in South-to- North water diversion, aiming at the problem of how to reduce water pollution problems on Dongping Lake during lake entrance project construction, construction key technology plan are discussed and applied, thereby ensuring project efficiency and water quality environment, and reducing project cost at the same time.
