摘要
移动模架不需要设置地面支撑,在施家梁立交桥的建设中使转跨周期缩小了2/3,大大提高了工作效率,经济效益也得到了显著的提高,且施工设备可重复利用,经济合理。施工时的受力与运营时受力一致,不需要增加施工受力钢筋,减少了建材消耗。
In the construction of Shijialiang Interchange, the ground support haven＇t movable frame, which makes the period of span-transfer reducing by 2/3, heightens ciency greatly, and advancing the economic benefit markedly. The construction method to be set for the work effi is economical and rational because the construction equipment can be reused. The stress in construction accords with that in operational period. It is not necessary to add force reinforcing steel bars in construction, thus the building material consumption is reduced.
