Research on Key Construction technology of Steel-Concrete Composite Arch Tower with Outer Steel Shell
The main tower of Jijie Bridge is a'diving'arch shaped cable tower,which adopts the steel shell steel-mixed composite structure to meet the needs of urban bridge aesthetic shape and structural stress.In order to meet the construction needs,according to the design requirements,the existing construction methods of cable tower assembly were used for reference in the construction,and a set of construction methods of steel shell segment installation technology,cable tower line monitoring technology,cable saddle positioning technology and temporary support technical measures of arch cable tower for steel-concrete composite arch cable tower crane with outer steel shell using tower crane method were summarized.It can provide a set of effective ways for the construction of similar special-shaped steel composite bridge tower by tower crane method,and provide a reference for the construction of special-shaped cable tower assembly.
