Description

用于水下砼浇注的连接式导管装置 技术领域
本发明涉及土木工程水下砼施工技术领域，特别是涉及一种用于水下砼浇注的连接式导管装置。
背景技术
随着科学技术和国民经济的发展，我国加大了交通基础设施的投资与建设。通江跨海工程、水中建筑工程越来越多，不可避免的修建水下结构、浇注水下砼。在水下浇注砼过程中，比如桩基、基础水下封底等，为保证砼避免受水的干扰，保持整体性、连续性，通常采用导管辅助浇注。导管由5-8mm厚的无缝钢管加工而成，为满足水下施工要求，通常由料斗和若干长度为2-4m的导管组成。砼浇注前，根据水深，逐节拼装至设计长度；随着水下砼的浇注，逐节拆除导管，并始终保证导管底部埋在砼中一定深度，同时导管(尤其接头位置)严格密封。整个水下砼施工过程中，导管逐节安装与拆除是关键，制约着施工效率和砼质量。目前导管常用连接形式为螺旋套筒连接式导管和法兰连接式导管。这两种连接方式，存在大量反复的旋拧、松紧螺纹操作，较为繁琐；连接螺纹较为精细，容易受损；同时水下密封性也不耐久。
