Main bridge closure section construction method
The invention discloses a main bridge closure section construction method, which belongs to the technical field of building construction. The structure comprises a Pm10-Pm11 side span closure section,a Pm12-Pm13 side span closure section and a mid-span closure section, the Pm10-Pm11 side span closure section adopts a floor type bracket as a closure section construction bracket, the Pm12-Pm13 sidespan closure section adopts a hanging basket as a closure section construction bracket, and the mid-span closure section adopts a hanging basket as a closure section construction bracket; the closuresequence of the main bridge continuous beam closure section construction method is as follows: firstly, the Pm10-Pm11 side span closure section and the Pm12-Pm13 side span closure section are closed,then temporary solidification is relieved, and then the mid-span closure section is closed. The formwork system is adopted, the construction process is mature, the precision is easy to control, and the overall linetype of a 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 and is erected with a side span cast-in-place section support at the same time, a bottom web formwork and aflange plate formwork can also be installed with the side span cast-in-place section at the same time, 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。它包括Pm10‑Pm11边跨合拢段、Pm12‑Pm13边跨合拢段和中跨合拢段，Pm10‑Pm11边跨合拢段采用落地式支架作为合拢段施工支架，Pm12‑Pm13边跨合拢段采用挂篮作为合拢段施工支架，中跨合拢段采用挂篮作为合拢段施工支架；主桥连续梁合拢段施工方法的合拢顺序为：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。
