Hydropower station water inlet breast wall connecting beam construction structure
The invention discloses a hydropower station water inlet breast wall connecting beam construction structure which comprises a dam body template, a breast wall template and a supporting structure hung between a poured dam body and a breast wall and used for supporting a connecting beam precast block. The lower surface of a precast block body of the connecting beam precast block is coplanar with the layered pouring surface of the top of the poured dam body and breast wall, the length of the precast block body is equal to the distance between the dam body and the breast wall, and a precast block extending steel bar of the connecting beam precast block extends into the space of the dam body and breast wall to be poured; doka template positioning cones are embedded in the poured dam body and breast wall, and positioning cone nuts are connected outside the Doka template positioning cones. According to the construction method, the connecting beam precast blocks are constructed, the connecting beam precast blocks are accurately hoisted by embedding the positioning cones in the early stage and installing the supporting structure, after concrete construction of the dam body and the breast wall is completed, the supporting structure is hoisted away and removed, construction is standardized and programmed, and the height of the upper portion of the jacking can be flexibly adjusted so that the installation elevation of the connecting beam can be accurately controlled.
本发明公开了一种水电站进水口胸墙连系梁施工结构，包括坝体模板、胸墙模板、以及挂接在已浇筑的坝体和胸墙之间且用于支撑连系梁预制块的支撑结构，连系梁预制块的预制块体的下表面与已浇筑的坝体和胸墙的顶部分层浇筑面共面，预制块体的长度等于坝体和胸墙之间的间距，连系梁预制块的预制块伸出钢筋伸入至待浇筑的坝体和胸墙的空间内，已浇筑的坝体和胸墙内均预埋有多卡模板定位锥，多卡模板定位锥外连接有定位锥螺母。本发明采取连系梁预制块施工，利用前期埋设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，施工标准化、程序化，可灵活调节顶托上部高度，以精确控制连系梁的安装高程。
