在役船闸增设导航墙结构及施工方案

针对在役船闸因采用同步移泊方式提升运行效率而需要增加或延长导航墙的问题，介绍在役船闸增设2种导航墙结构与其施工方案。以葛洲坝2#船闸和三峡船闸为例，对在役船闸增设2种导航墙结构及其施工流程进行详细阐述。结果表明，对比于传统导航墙结构与施工方式，这2种导航墙结构与其施工方案能够满足运行需求，同时有效减少工期且不影响施工期船舶通航，为大多数在役船闸增设导航墙提供对自身运行影响更小的结构。

Structure and construction plan of adding navigation wall to in-service ship lock

In order to solve the problem that the navigation wall needs to be added or extended due to the synchronous berthing mode to improve the operation efficiency of the in-service ship locks,we introduce the structure and construction scheme of two additional navigation walls in the in-service ship locks.Taking Gezhouba No.2 ship lock and Three Gorges ship lock as examples,we elaborate the construction process of in-service ship locks with the two navigation wall structures.The results show that compared with the traditional navigation wall structure and construction method,in-service ship locks with the two navigation walls can meet the operation requirements,and effectively reduce the construction period without affecting the navigation of ships during the construction period,and provide structural and construction scheme options with less impact on their own operation for most in-service ship locks.
