摘要
某跨河桥设计为3跨预应力混凝土箱梁结构,箱梁临时支架采用满堂红钢管碗扣式支架搭设。因有通航要求,河内需搭设过河门洞,门洞横梁采用I50b。详细介绍了支架区域的地基处理,临时支架的设计,以及支架施工技术,保证了主体桥梁的施工安全。
A cross-river bridge is designed as a three-span prestressed concrete box girder structure,and the temporary support of the box girder is set up with a bowl of buckles.The navigation requirements need set up a translator crossing the river gate in river,and the door beam is made of I50b beam.This paper introduces the foundation treatment of the support area in detail,the design of temporary support,and the support construction technology,which ensure the construction safety of the main bridge.
