0#桥台现浇段下方地势经过开挖后较为平坦,且高度不大,但是两边较窄,为了便于以后的拆除及吊装,采用满堂式钢管支架方案进行施工。
After the excavation, the topography of the 0 # abutment under the cast-in-site section is relatively flat, and the height is not large, but the two sides are narrower. In order to facilitate the later dismantling and lifting, the full-scale steel pipe support scheme is used for construction.
