Steel-concrete combined section construction method, steel pylon and cable-stayed bridge
The invention provides a steel-concrete combined section construction method, a steel pylon and a cable-stayed bridge, and relates to the technical field of bridge construction. The steel-concrete combined section construction method comprises the following steps that S1, an anchor beam positioning frame and an anchor rod positioning frame are installed on a bearing platform, and an anchor beam and an anchor rod are accurately positioned and installed; s2, an external support is installed on the bearing platform, and a three-dimensional jack and a base plate are installed on the upper portion of the external support; s3, a bracket is fixed to the middle of the outer side of the steel-concrete combined section, the steel-concrete combined section is hoisted to the outer support, the posture of the steel-concrete combined section is adjusted through a three-dimensional jack, and then the steel-concrete combined section is welded and fixed to the outer support; and S4, follow-up construction such as concrete pouring, curing and tensioning is conducted. The posture of the steel-concrete combined section can be accurately adjusted, the steel-concrete combined section is effectively fixed, the deviation and torsion problems of the steel-concrete combined section in the concrete pouring process are greatly solved, and the mounting precision of the steel-concrete combined section is improved.
本发明提供一种钢混结合段施工方法、钢索塔及斜拉桥，涉及桥梁施工技术领域。钢混结合段施工方法包括以下步骤：S1：在承台上安装锚梁定位架与锚杆定位架，精确定位安装锚梁与锚杆；S2：在承台上安装外部支架，在外部支架的上部安装三维千斤顶与垫板；S3：在钢混结合段的外侧中部固定牛腿，吊装钢混结合段至外部支架上，通过三维千斤顶调整钢混结合段的姿态，然后将钢混结合段焊接固定至外部支架上；S4：进行混凝土浇筑、养护、张拉等后续施工。本申请可精确调整钢混结合段的姿态，并使钢混结合段得到有效固定，极大消除钢混结合段在混凝土浇筑过程中的偏位和扭转问题，提高钢混结合段的安装精度。
