Non-vertical surface concrete pouring formwork erecting device and method and overflow surface construction method
The invention discloses a non-vertical face concrete pouring formwork erecting device and method and an overflow face construction method, and belongs to the technical field of hydraulic engineering. The formwork erecting method comprises the steps that a lofting point is arranged on a concrete bin face, a plurality of vertical steel bars with the preset length are pre-buried at the lofting point, and the anchoring depth of the vertical steel bars is larger than or equal to 10 cm; transverse reinforcing steel bars and longitudinal reinforcing steel bars are installed among the multiple vertical reinforcing steel bars, the transverse reinforcing steel bars and the longitudinal reinforcing steel bars are horizontally installed, lofting is conducted at the preset height of the upper portions of the vertical reinforcing steel bars, a reinforcing steel bar net is installed according to the lofting position, and formwork sample frame reinforcing steel bars are installed above the reinforcing steel bar net according to the same lofting position; a preset distance is reserved between the formwork sample frame reinforcing steel bars and the reinforcing mesh, a plurality of panels are laid on the formwork sample frame reinforcing steel bars to assemble the formwork, surrounding purlins are installed on the panels, and the surrounding purlins and the reinforcing mesh are fixed through formwork braces. The technical problems that the construction cost of an overflow surface with a large curved surface and a small slope is high, the engineering difficulty is high, hoisting equipment is needed or the lofting work is heavy can be solved.
非竖直面混凝土浇筑立模装置及方法和溢流面施工方法，属于水利工程技术领域，其中立模方法包括在该混凝土仓面上设置放样点，在放样点处预埋若干预设长度的竖直钢筋，竖直钢筋的锚固深度≥10cm，在多个竖直钢筋之间安装横向钢筋和纵向钢筋，横向钢筋和纵向钢筋均为水平安装，在竖直钢筋上部预定高度处放样并根据放样位置安装钢筋网，在钢筋网上方根据同样的放样位置安装模板样架钢筋，模板样架钢筋与钢筋网之间留出预设间距，在模板样架钢筋上铺设多个面板以组装成模板，在面板上安装围檩，将围檩与钢筋网通过模板拉条进行固定。本发明能够解决曲面较大、坡比较小的溢流面施工成本大、工程难度大、需要吊装设备或放样工作繁重等技术问题。
