Hydropower station water inlet breast wall connecting beam construction method
The invention discloses a hydropower station water inlet breast wall connecting beam construction method. The method comprises the steps that firstly, a plurality of connecting beam prefabricated blocks are prefabricated; 2, constructing a layer of dam body and a breast wall; 3, mounting a positioning cone nut on the doka template positioning cone; fourthly, a supporting structure is installed and adjusted; fifthly, the connecting beam precast blocks are hoisted; sixthly, a dam body formwork and a breast wall formwork are installed; seventhly, the next layer of dam body and breast wall are poured; 8, the supporting structure is adjusted away; and 9, repeating the steps 3-8 for many times until the construction is finished. According to the construction method, the connecting beam precast blocks are manufactured firstly, the connecting beam precast blocks are accurately hoisted by utilizing the positioning cones embedded in the earlier stage and mounting the supporting structures, and after dam body and breast wall concrete construction is completed, the supporting structures are hoisted away and removed, so that instrumentalization, standardization and programming of hydropower station water inlet breast wall connecting beam construction are achieved, construction is convenient and fast, and the construction efficiency is improved. The height of the upper portion of the jacking can be flexibly adjusted so as to accurately control the installation elevation of the connecting beam, and the supporting structure can be repeatedly used.
本发明公开了一种水电站进水口胸墙连系梁施工方法，包括步骤：一、预制多个连系梁预制块；二、施工一层坝体和胸墙；三、在多卡模板定位锥上安装定位锥螺母；四、安装支撑结构并调节支撑结构；五、吊装连系梁预制块；六、安装坝体模板和胸墙模板；七、浇筑下一层坝体和胸墙；八、调离支撑结构；九、多次重复步骤三至八，直至施工完毕。本发明通过先进行连系梁预制块制作，利用前期埋设的定位锥并安装支撑结构进行连系梁预制块的准确吊装，待坝体和胸墙混凝土施工完成后，再吊离拆除支撑结构，实现水电站进水口胸墙连系梁施工的工具化、标准化、程序化，施工便捷，可灵活调节顶托上部高度，以精确控制连系梁的安装高程，支撑结构可重复利用。
