Integral hoisting construction method for tied-arch bridge
The invention discloses an integral hoisting construction method for a tied arch bridge, which comprises the following steps: step 1, construction preparation: firstly, cleaning a construction site, and erecting a construction bracket; 2, processing and transporting the arch rib; thirdly, on-site assembling of the arch ribs is conducted; 4, arch section cast-in-place is conducted, specifically, the sequentially-conducted procedures include arch section cast-in-place support installation, arch section cast-in-place bottom die and arch section support pre-pressing, then arch foot pre-buried sections and tie bar pipelines are installed, and finally arch section cast-in-place section concrete pouring and arch foot concrete pouring are conducted; 5, overall installation of the arch ribs; sixthly, beam part construction is conducted; and (7) after the work procedures are completed, the temporary consolidation outer cable is dismantled firstly, and then suspender dismantling work of suspender tensioning is conducted. The integral hoisting of the arch bridge is carried out through the construction method of'arch first and beam second ', and the problem of traffic interruption caused when the tied-arch bridge crosses a road or a channel in the implementation process of the'beam first and arch second' method in the traditional technology is effectively solved.
本发明公开了一种系杆拱桥整体吊装工法，包括如下步骤：步骤一：施工准备，首先对施工场地进行清理，并搭设施工的支架；步骤二：拱肋的加工和运输；步骤三：拱肋的现场拼装；步骤四：拱段现浇，依次进行的工序包括拱段现浇支架安装、拱段现浇底模和拱段支架预压，然后进行拱脚预埋段及系杆管道安装，最后进行拱段现浇段浇筑混凝土，拱脚混凝土浇筑；步骤五：拱肋的整体安装；步骤六：梁部施工；步骤七：在完成以上工作流程后，先拆除临时固结体外索，再进行吊杆张拉的拆除吊杆工作。本发明通过“先拱后梁”的施工方法来进行拱桥的整体吊装，有效解决了传统技术中“先梁后拱”法实施过程中系杆拱桥跨越道路或航道时导致的交通中断的问题。
