Construction method for bridge floor steel beam sections of double-tower double-cable-plane steel-concrete composite beam cable-stayed bridge
The invention relates to a double-tower double-cable-plane steel-concrete composite beam cable-stayed bridge deck steel beam section construction method, and belongs to the technical field of cable-stayed bridge construction. Comprising the following steps that S1, a storage platform is erected; s2, a hoisting mechanism is erected; s3, mounting a bracket; s4, assembling a first section of steel beam; s5, lapping a first section of steel beam; s6, bridge deck slabs are erected; s7, a next steel beam section is erected, specifically, the spliced steel beam section in the storage platform is lifted to the top face of the bracket through a lifting station and erected through a suspended splicing crane, and meanwhile corresponding stay cables are hung and tensioned on the steel beam section; s8, the construction steps S6-S7 are repeated, and the bridge deck slab and the steel beam sections are erected through the tower crane and the lifting station; the storage platform is composed of a rod piece storage area, a steel frame splicing area and a vehicle passing area. The problems that when an existing steel-alkali superposed beam cable-stayed bridge is constructed through a single crane and an integrated suspension splicing device, the construction efficiency is low, the construction precision is low, and the construction procedure is complex are solved.
本发明涉及一种双塔双索面钢混组合梁斜拉桥桥面钢梁节段施工方法，属于斜拉桥施工技术领域。包括以下步骤：S1：搭设存放平台；S2：搭设吊装机构；S3：托架安装；S4：首节钢梁拼装；S5：搭接首节钢梁；S6：桥面板搭设；S7：下一钢梁段搭设，将存放平台内拼接完成的钢梁段通过提升站提升至托架顶面并通过悬拼吊机进行搭设，同时在钢梁段挂设并张拉对应斜拉索；S8：重复施工步骤S6‑S7，利用塔吊和提升站对桥面板和钢梁节段进行搭设；存放平台由杆件存放区、钢架拼装区和车辆通行区构成本发明解决了现有的钢‑硷叠合梁斜拉桥在采用单一吊机和一体式悬拼装置进行施工时施工效率低、施工精度低和施工工序复杂的问题。
