Continuous beam arch bridge of steel web-concrete combined box beam and construction method
The invention discloses a continuous beam arch bridge of a steel web-concrete combined box girder and a construction method.The continuous beam arch bridge comprises a girder body, arch ribs and suspenders, the girder body comprises a steel web-concrete combined box girder section, a concrete girder section and a girder section transition combination area connecting the steel web-concrete combined box girder section and the concrete girder section, and the concrete girder section is arranged near a middle fulcrum and side fulcrums; the steel web-concrete combined box girder section is arranged on the middle span or arranged on the middle span and the side span at the same time, and the arch rib is connected with the steel web-concrete combined box girder section through a suspender. The construction method comprises the following steps that the concrete beam section and the beam section transition combination area are constructed; the steel web section is machined; the steel web part sections are assembled through cantilevers till the steel web parts are closed; constructing arch ribs; mounting a suspender; a concrete part is poured, and segmented tensioning is conducted; and finally tensioning the suspenders, dismantling the full framing, and carrying out system conversion to form a bridge. The steel web-concrete combined box girders are used for part of the main girder sections, the sections are light in weight, the field operation amount is small, and the construction speed is high.
本发明公开了一种钢腹板‑混凝土组合箱梁的连续梁拱桥及施工方法，其连续梁拱桥，包括梁体、拱肋和吊杆，梁体包括钢腹板‑混凝土组合箱梁段、混凝土梁段以及连接二者的梁段过渡结合区，混凝土梁段布置于中支点和边支点附近，钢腹板‑混凝土组合箱梁段布置于中跨或同时布置于中跨、边跨，拱肋与钢腹板‑混凝土组合箱梁段通过吊杆连接。施工方法，包括以下步骤：施工混凝土梁段和梁段过渡结合区；加工钢腹板部节段；悬臂拼装钢腹板部节段至钢腹板部合龙；施工拱肋；安装吊杆；浇筑混凝土部并分段张拉；对吊杆进行终张拉，拆除满堂支架进行体系转换，成桥。本发明中部分主梁节段用钢腹板—混凝土组合箱梁，节段重量轻，现场作业量少、施工速度快。
