摘要:: 为保证水利工程水流顺畅,一般溢流堰面由曲线段+直线段+弧线段组成,使堰面成为高速过水面,直接影响使用功能和外观质量。通过在堰体规定的位置测设模板承托装置位置,预埋锚栓,作为堰体面层钢筋支架的定位点,同时采用三点固定法,在模板承托装置处安装钢筋支架,结合模板缝位置布置,与事先预埋的锚栓焊接,最后根据设计图纸堰面制作、安装、混凝土浇筑、养护、拆模等操作的施工方法,确保溢流堰坝曲线堰面的混凝土外观质量。

Abstract:: In order to ensure the smooth flow of hydraulic engineering water, the surface of the overflow weir is generally composed of curve section, straight line section, arc line section, making the weir surface a high-speed water surface, which directly affects the use function and appearance quality. By measuring the position of the formwork supporting device at the specified position of the weir body, the anchor bolts were embedded as the positioning point of the reinforcement support of the weir body surface layer. At the same time, using three-point-suturing method, installing the reinforcement support at the formwork supporting device, combined with the location of the formwork joint, welding with pre-embedded anchor bolts, and finally according to the construction method of the design drawing weir surface production, installation, concrete pouring, curing and mold removal to ensure the concrete appearance quality of the curved weir surface of the overflow weir.
