Abstract: The extension of Hangzhou on line 01 marked the elevated pond canal bridge Cantilever construction project.
Key words: continuous rigid frame bridge Cantilever Diamond Hanging Basket
First, project survey
The toro toro extended line is the interface between the wiring and the Hangzhou-Ningbo Expressway project, the project across the upper canal structure 72 +120 +72 m of continuous rigid frame bridge, 1% longitudinal and transverse single-box single Long Cantilever structure, the main pier Department beam high-6.8m, cross-beam with high-side pier Office 2.5m, beam height and floor height by the second parabola. Box top width of 18.62m, bottom width 10m, Cantilever 4.31m, roof thickness 30cm, floor thickness changes by 30 ~ 100cm, web thickness of 60cm.
Main pier double Piers, base φ180cm bored piles, pile cap, size 17.3 × 8.6 × 3.5m. In the 120m 1 / 2 length is divided into 14 segments in which segment # 0 long 8.5m, 1 ~ 2 號(hào) segment length 3.0m, 3 ~ 7 號(hào) segment length 3.5m, 8 ~ 14 號(hào) segments
