葛洲坝船闸浮门浮式系泊装置方案研究

在原葛洲坝2号船闸上游导航墩上增设浮式系泊装置,涉及到工程选址、结构方案、施工围护、水下施工等诸多问题,尤其是在不影响正常通航情况下,如何以最经济、安全可靠的方式进行工程施工是本项目的核心问题.研究结果表明采用围护结构与模板结构、受力结构三者合一的钢筒体系,是降低水下施工难度与解决上述问题的有效途径,在同类工程项目中属首创,可供其他同类项目借鉴.

Research on Mooring Arrangement Scheme for Floating Repair Gate of Ship Lock at Gezhouba Project

The research on adding mooring arrangement on the original No.2 ship lock of Gezhouba project includes choosing address,structural scheme,construction outer protective scheme,under-water construction and so on.Especially in the occasion of unaffecting normal navigation,how to finish this program in the most economical and secure way is the core problem.The research results indicate that the steel tube structure which has three structural effects of construction outer protective structure,mounding board structure and loaded structure.It is an effective way to settle up the above problem and reduce the difficulty of under-water construction.As the first initiation in the similar engineering projects,the research provides some quotable values.
