Steel reinforced concrete cable bent tower of cable-stayed bridge and construction method thereof
The invention discloses a steel reinforced concrete cable bent tower of a cable-stayed bridge and a construction method thereof, and belongs to the technical field of cable bent tower construction of cable-stayed bridges. The cable-stayed bridge cable tower and the construction method thereof are suitable for complex geological conditions and high-intensity earthquake areas. According to the technical scheme, the steel reinforced concrete cable bent tower of the cable-stayed bridge comprises a main pier, a lower tower column and an upper tower column, and the structure of a main pier steel reinforced part in the main pier is that four cross-shaped steel columns are located at the four corners, and two rows of steel sections are arranged between every two adjacent cross-shaped steel columns and comprise inner-layer steel sections and outer-layer steel sections; the lower tower column profile steel reinforcing part in the lower tower column comprises a cross-shaped steel column extending upwards, inner-layer profile steel and outer-layer profile steel. The cable bent tower construction method comprises the steps that the main pier bearing platform is constructed; the cross-shaped steel column is hoisted; hoisting the I-shaped steel beam; hoisting the inner-layer profile steel and the outer-layer profile steel; pouring a main pier; the cross-shaped steel column, the inner-layer profile steel and the outer-layer profile steel extend upwards; pouring a lower tower column; and pouring the upper tower column. The method is suitable for construction of the cable-stayed bridge tower.
本发明一种斜拉桥型钢混凝土索塔及其施工方法，属于斜拉桥索塔施工技术领域。目的在于提供一种适用于复杂地质条件和高烈度震区的斜拉桥索塔及其施工方法。采用如下技术方案，斜拉桥型钢混凝土索塔包括主墩、下塔柱和上塔柱，主墩中主墩型钢加固部分的结构为：四根十字型钢柱位于四角，相邻的两根十字型钢柱之间均设置有两排型钢，为内层型钢和外层型钢；下塔柱中下塔柱型钢加固部分包括向上延伸的十字型钢柱、内层型钢和外层型钢。上述索塔施工方法为：施工主墩承台；吊装十字型钢柱；吊装工字钢梁；吊装内层型钢和外层型钢；浇筑主墩；十字型钢柱、内层型钢和外层型钢向上延伸；浇筑下塔柱；浇筑上塔柱。本发明适用于斜拉桥索塔的施工。
