Steel structure bridge box girder cast-in-place closure section shared supporting system and construction method thereof
The invention belongs to a steel structure bridge box girder cast-in-place closure section shared supporting system and construction method thereof. The construction method comprises the steps of piercolumn bearing platform construction, pier column construction, shared supporting system building, steel structure cast-in-place box girder bottom die or closure section cast-in-place bottom die installation, on-site box girder pouring or closure section box girder pouring on the cast-in-place box girder bottom die or closure section cast-in-place bottom die in sequence, prestress tensioning, diedismounting and shared supporting system dismounting. According to the invention, the supporting system shared by the cast-in-place section and the closure section can be built on a narrow pier column bearing platform, the problem that the construction cost of the overwater cast-in-place section and the closure section of a bridge is high and the risk is large is solved, and the supporting systemhas the advantages of reducing the investment of overwater construction cost, saving cost, shortening the construction period and reducing the construction safety risk.
本发明属于一种钢构桥箱梁现浇合拢段共用支撑系统及其施工方法，包括如下步骤：墩柱承台施工、桥墩柱施工、搭建共用支撑系统、安装钢构现浇箱梁底模或合拢段现浇底模和在现浇箱梁底模或合拢段现浇底模上依次进行现段浇箱梁或合拢段箱梁浇筑、预应力张拉、拆模、拆除共用支撑系统。本发明能在狭小的墩柱承台上搭建供现浇、合拢段共用支撑系统，解决了大桥水上现浇段及合拢段施工成本高风险大的难题，具有减少水上施工费用的投入,节省成本，缩短工期，降低施工安全风险的优点。
