Steel arch rib outer wrapped concrete construction method for steel trussed arch bridge
The invention discloses a steel arch rib outer wrapped concrete construction method for a steel trussed arch bridge and relates to the technical field of building construction of steel trussed arch bridges. The construction method includes the steps that each steel arch rib section to be poured with concrete is provided with a hanging bracket system and a bottom formwork; after installation is finished, bottom board reinforcing steel bars are tied; each hanging bracket system is used for erecting a construction support and an operation platform, web reinforcing steel bars and a web formwork of a first ring construction section are installed, and the outer wrapped concrete is poured to the first ring construction section; after the concrete is poured, an inner cavity support and a platform are erected, a high construction support and an operation platform are connected, reinforcing steel bars and a formwork of a second ring construction section are installed, and the outer wrapped concrete is poured to the second ring construction section; and after the concrete is poured, outer wrapped concrete construction of the next steel arch rib section is started, and the operation is repeated till the concrete is poured to all the steel arch rib sections. By the adoption of the method, the construction difficulty is lowered, the application range is wide, construction efficiency is effectively improved, construction safety is guaranteed, and adaptability and economical efficiency are high.
