Large-water-head tidal zone steel sheet pile cofferdam construction method
The invention relates to a construction method of a large-water-head tidal zone steel sheet pile cofferdam. The construction method comprises the steps that longitudinal and transverse guide frames are installed; constructing a pile casing hoop system; mounting an inner upper-layer steel support; construction of Larsen steel sheet piles; building a central area construction platform; inner side lower-layer steel supports are installed; and silt digging, foundation cleaning and concrete pouring are conducted in the cofferdam. The guide frame has the beneficial effects that the stability of the longitudinal guide frame is effectively improved through the rigid pull rods and the flexible pull ropes, then the stability of the whole guide frame system is improved, and rapid installation of the longitudinal guide frame and the transverse guide frame is achieved through the I-shaped preformed holes; high-precision construction of the Larsen steel sheet pile is achieved in the mode that a track is preset and fine adjustment jacking equipment is installed. The central area construction platform is arranged, so that a safe and convenient operation space is provided for silt digging and foundation cleaning in the cofferdam and concrete bottom sealing construction; and a water level monitor and an axial force meter are arranged to dynamically monitor the support and the water level in the cofferdam.
本发明涉及一种大水位差潮汐带钢板桩围堰施工方法，包括步骤：纵横向导向框架安装；护筒抱箍体系施工；内侧上层钢支撑安装；拉森钢板桩施工；中央区施工平台搭设；内侧下层钢支撑安装；围堰内挖淤清基和混凝土浇筑。本发明的有益效果是：通过刚性拉杆与柔性拉绳有效提升纵向导向框架的稳定性，进而提升整个导向框架体系的稳定性，工字型预留孔实现了纵横向导向框架的快速安装；通过预设轨道并安装微调顶升设备的方式，实现拉森钢板桩的高精度施工；设置中央区施工平台为围堰内挖淤清基以及混凝土封底施工提供了安全且便利的作业空间；设置水位监测仪及轴力计对围堰内支撑及水位实现动态监控。
