类矩形隧道管片吊装及翻转吊具关键技术研究

Key Techniques for the Segment Hoisting and Flipping Devices of Quasi-Rectangle Tunnels

大型隧道管片的翻转是管片制造工艺过程的一个关键作业,其更需要符合安全、准确、可靠、免碰、效率高和操作方便等要求。文章介绍了一种针对隧道管片翻转的工艺和相关操作要求的新工艺,以及相应的翻转吊装夹具,其研究思路和方法具有一定的推广价值。

Flipping is a key operation for the segment manufacturing process of large tunnels,and it needs meeting the requirements of safety,accuracy,reliability,no collision,high efficiency and convenient operation,etc..In this paper a new flipping technique and relevant hoisting clamps are introduced based on the existing techniques and requirements.
