Construction method for concrete jacking of arch rib of steel tube tied-arch bridge
The invention discloses a construction method for concrete jacking of an arch rib of a steel tube tied-arch bridge. The method comprises the steps of concrete jacking preparation work, concrete mixingratio, concrete pump pipe arrangement, concrete jacking construction, abnormal condition treatment measures and the like. According to the construction method for concrete jacking of the arch rib ofthe steel tube tied-arch bridge, the operation process and used equipment are simple, scaffold erection for construction is not needed, the compactness of the concrete in the arch rib can be guaranteed through the combination of a high-pressure concrete pump truck and an effective construction method, and the safety of construction operation is enhanced. The construction risk is reduced, and the operation efficiency is improved.
一种钢管系杆拱桥拱肋混凝土顶升的施工方法。其包括混凝土顶升准备工作，混凝土的配合比、混凝土泵管的布置，混凝土顶升施工，异常情况处理措施等步骤。本发明提供的钢管系杆拱桥拱肋混凝土顶升的施工方法操作过程及所用设备简单、无需搭设脚手架施工，利用高压混凝土泵车结合有效的施工方法，能够保证拱肋内混凝土的密实性，施工作业的安全性得到了增强。降低了施工风险，提高了作业效率。
