摘要
桃源水电站船闸下游引航道主导航墙有450 m位于一期围堰之外,如另做子围堰旱地施工,工期难以保证且投资较高。为解决上述问题,充分利用引航道的地形、地质条件,对下游引航道主导航墙结构型式进行了多方案比选,最终采用"混凝土桩+高喷基础"方案,达到了取消子围堰施工、节省工期、节约投资之目的。
The downstream main approach channel wall of ship lock in Taoyuan Hydropower Station has a section of 450m-long located outside the Phase I cotterdam. It is difficult to meet the requirements on construction period and investment if this section approach channel wall is constructed on a dry condition by building a sub-cofferdam. For solving these problems, different structure types of main approach channel wall are compared, and the combination of concrete piles and high-pressure jet grouting foundation are finally determined to be used after considering the topographic and geologic conditions of approach channel.
