葛洲坝1号船闸增设防撞安全设施的探讨

Adding anti-collision safety device for Gezhouba No.1 Lock

葛洲坝1号船闸由于与三峡船闸匹配运行,船舶实行导航墙待闸,下行船舶在导航墙停靠时距离人字门较近,而且下行船舶首船进闸后停靠位置与下闸首人字门距离较近,都具有碰撞人字门的风险。针对葛洲坝1号船闸人字门存在被碰撞的风险,结合上、下闸首的现场情况分别就上、下闸首人字门增设防撞设施方案的可能性进行分析,提出提升式、侧开式和下沉式等方案,并讨论各方案实现的可能性、优势及不足,为船闸人字门防撞安全设施的方案设计及应用提供参考。

Due to the matching operation of Gezhouba No. I Lock and the Three Gorges Lock, ships are docked at the navigation wall, the first downwards ship at the upstream navigation wall is close to the miter gates, and the ship after entering the lock is also close to the downstream miter gates. In both cases there are risks of colliding with the miter gates. For the existing risk, the possibility of adding anti-collision facilities for the upper and lower miter gates is analyzed combining with the upper head and lower head in the lock, and three schemes are proposed, i.e. the lifting scheme, the side-opening scheme, and the sinking scheme, the possibility, advantage and deficiency of which are discussed and reference is provided for the design and application of the collision safety device of the miter gate.
