Construction method for assisting in construction of extradosed cable-stayed bridge H-shaped tower through stiff framework
The invention discloses a construction method for auxiliary construction of an H-shaped tower of an extradosed cable-stayed bridge through a stiff skeleton. A tower column is divided into a bottom tower section area, a cable-free area tower section area and a cable area tower section area from bottom to top; a bottom reinforced stiff framework, a cable-free area stiff framework and a cable area stiff framework are correspondingly arranged in the three tower section areas respectively, the bottom reinforced stiff framework, the cable-free area stiff framework and the cable area stiff framework are prefabricated respectively, and positioning comb plates are fixedly arranged on the peripheries of the bottom reinforced stiff framework, the cable-free area stiff framework and the cable area stiff framework; the stiff skeleton in the cable area is divided into a plurality of stiff skeleton sections in the height direction of the tower column, and each stiff skeleton section comprises a wire dividing pipe positioning frame; all tower section areas are constructed section by section from bottom to top according to the working procedures of stiff framework hoisting, steel bar binding, formwork installation, concrete pouring and formwork removal; and the two tower columns are synchronously constructed, and the cross beams are synchronously constructed when the corresponding tower section areas are constructed. The construction requirements of the H-shaped tower of the extradosed cable-stayed bridge can be met, and the construction efficiency is effectively improved.
本发明公开了一种劲性骨架辅助施工矮塔斜拉桥H型塔的施工方法，将塔柱由下向上划分为底部塔段区域、无索区塔段区域和有索区塔段区域；三个塔段区域内分别对应设置有底部加强型劲性骨架、无索区劲性骨架和有索区劲性骨架，底部加强型劲性骨架、无索区劲性骨架和有索区劲性骨架分别预制，且外周均固定设置有定位梳齿板；有索区劲性骨架沿塔柱高度方向划分为多个劲性骨架节段，每个劲性骨架节段均包括一个分丝管定位架；各塔段区域按照劲性骨架吊装、钢筋绑扎、模板安装、混凝土浇筑、模板拆除的工序由下至上分节段施工；两个塔柱同步施工，横梁在对应的塔段区域施工时同步进行施工。本发明可以满足矮塔斜拉桥H型塔的施工要求，有效提高施工效率。
