摘要
经公伯峡水电站左岸泄洪洞进水塔混凝土施工方案比较,采取在进口边坡高程1 981.0 m的宽马道上布置1台DMQ600A/30 t高架门机,满足了进水塔、贴坡及进水塔交通桥的施工要求。根据现场地质勘测以及对门机基础进行稳定分析计算,表明门机基础处于稳定状态。通过2 a多的运行,亦验证了门机基础处于稳定状态。
Through comparison with the construction scheme of concrete placement of intake tower of the flood discharge tunnel on left bank, Gonghoxia Hydropower Project, one high gantry crane of DMQ6OOA/30 t is provided on the wide berm at EL. 1981.0 m on the inlet slope. This installation satisfies construction requirements of intake tower, slope protection and access bridge of the intake tower. Through the site geological investigation, stability analysis and calculation on the foundation of the gantry crane, it shows that the gantry crane foundation is in stable condition. Meanwhile, more than 2a-year operation verifies the gantry crane foundation in the stable condition.
