Construction method for closure section of main bridge
The invention discloses a main bridge closure section construction method and belongs to the technical field of building construction. Comprising the steps that firstly, a Pm10-Pm11 side span closure section and a Pm12-Pm13 side span closure section are closed, then temporary consolidation is relieved, and then a mid-span closure section is closed. The formwork support system is adopted, the construction technology is mature, precision is easy to control, and the overall line type of the bridge is guaranteed; the side span closure section support and the side span cast-in-place section support are connected into a whole, the system is stable, and the construction safety is high; the side span closure section adopts a floor bowl buckle support system, the side span closure section and a side span cast-in-place section support are erected at the same time, a bottom web formwork and a flange plate formwork can also be installed at the same time with the side span cast-in-place section, the construction time is shortened, and the construction efficiency is improved.
一种主桥合拢段施工方法，属于建筑施工技术领域。包括先合拢Pm10‑Pm11边跨合拢段和Pm12‑Pm13边跨合拢段，再解除临时固结，后合拢中跨合拢段。本发明采用支模架体系，施工工艺成熟，精度易于控制，保证桥梁整体线型；边跨合拢段支架与边跨现浇段支架连成一体，体系稳定，施工安全性高；边跨合拢段采用落地碗扣支架体系，与边跨现浇段支架同时搭设，底腹模板和翼缘板模板也可与边跨现浇段同时安装，缩短了施工时间，提高了施工效率。
