Hyperbolic concrete arch dam formwork system and construction method
The invention provides a hyperbolic concrete arch dam formwork system and a construction method, and the hyperbolic concrete arch dam formwork system comprises six parts, namely a panel structure, a supporting structure, an anchoring structure, a tripod lifting structure, a starting bin formwork structure and a gate hole cantilever bracket formwork system. The panel structure and the supporting structure are combined to form a large half-cantilever combined formwork system, the large half-cantilever combined formwork system is fixed through an anchoring structure, every time a layer of the standard bin is poured, the large half-cantilever combined formwork system is lifted and slid upwards by one layer through a triangular frame lifting structure, and the large half-cantilever combined formwork system is fixed through an anchoring structure. The formwork erecting efficiency of the double-curvature arch dam is improved; a foundation bolt is embedded in a dam foundation of a starting bin to tension an L-shaped enclosing purlin to support a starting bin formwork system, the problems of formwork shifting and formwork expanding during concrete pouring of the starting bin are solved, a profile steel pulling gate hole cantilever bracket formwork system is embedded in a standard bin, and the problems that a water gate hole bracket is large in cantilever size and large in cantilever angle are solved. And a conventional technology cannot be adopted to erect a scaffold for formwork erecting.
本发明提供双曲混凝土拱坝模板体系及施工方法，双曲混凝土拱坝模板体系包括六个部分，分别为面板结构、支撑结构、锚固结构、三角架提升结构、起始仓模板结构、闸孔悬挑牛腿模板体系，所述面板结构、支撑结构两部分组合为半悬臂大型组合模板体系，所述半悬臂大型组合模板体系通过锚固结构进行固定，所述标准仓每浇筑一层，采用三角架提升结构将半悬臂大型组合模板体系向上提升滑移一层，提高了双曲拱坝的支模效率；起始仓坝基预埋地脚螺栓拉紧L型围檩支设起始仓模板体系，解决了起始仓在浇筑混凝土时跑模、胀模的问题，所述标准仓内预埋型钢拉设闸孔悬挑牛腿模板体系，解决了水闸孔牛腿悬挑尺寸大，无法采用常规技术搭设脚手架进行支模的难题。
