Steel box girder combined type lifting system and construction method thereof
The invention relates to a steel box girder combined type lifting system and a construction method thereof, and the steel box girder combined type lifting system comprises a junction pier arranged atthe junction of water and land, a pushing support installed on the land and arranged side by side with the junction bridge pier in a longitudinal bridge direction, a main truss structure having one end fixed to the junction pier through a supporting device and the other end anchored to the pushing support through a rear anchoring device, and a lifting device used for lifting the steel box girder and fixed on the main truss structure. According to the steel box girder combined type lifting system and the construction method thereof, the using amount of steel is greatly reduced, girders can be taken out of water, and the passing safety of underbridge navigation in the construction period is guaranteed; the Yangtze River waterway is prevented from being occupied too much; the structure is light, economical and reasonable, the stress is simple and clear, the lifting is stable and uniform, the lifting is continuous and rapid, and the generalization performance is strong.
本发明涉及一种钢箱梁复合式提升系统及其施工方法，其包括：交界桥墩，设于水、陆交界处；顶推支架，安装于陆地上，且与所述交界桥墩沿纵桥向并排设置；主桁结构，其一端通过支撑装置固定于所述交界桥墩，另一端通过后锚装置锚固于所述顶推支架；用于吊装钢箱梁的提升装置，其固定于所述主桁结构。本发明涉及的一种钢箱梁复合式提升系统及其施工方法，大大节省钢材使用量，能在水中取梁，保障施工期间桥下通航的通行安全；且少占用长江航道，结构轻便、经济合理，受力简单明确，提升稳步匀速、连续快捷，推广性强。
