尼尔基水利枢纽尾水闸墩及下游墙采用了滑模施工技术,因其具有滑模结构不对称,下游墙频繁收台,模体频繁安拆的特点,使得该次滑模施工突破了常规的固定断面施工。介绍了变断面滑模施工的原理、结构设计和施工方法,与常规施工方法对比表明,其在质量、进度、效益等方面均具有优越性。
The slip-form construction technology is adopted for the tail gate pier and the downstream wall of the Nierji water conservancy project. Due to its asymmetric sliding-mode structure, frequently receiving of downstream walls and frequent demolition of the mold body, the slipform construction breaks through the conventional The fixed section construction. The principle, structural design and construction method of variable cross section sliding mode construction are introduced. Compared with conventional construction methods, it shows that it has superiority in terms of quality, schedule and benefit.
