摘要
在悬浇混凝土桥梁施工中,水箱放水和抛掷沙袋是合龙段施工中两种比较成熟的施工技术。但在特殊条件下,合龙段的施工受到时间和温度的严格限制。位于十堰的将军河大桥在合龙段施工中使用了挂篮作为合龙段的平衡重,通过测量数据,发现这种方法是比较适用的。
In cantilever cast-in-place concrete bridge, water and sand-bags unloading are two kinds of ripe construction techniques in closing up a section. But under special condition, the construction of closure section is restricted by time and temperature, the Jiangjun river bridge in Shiyan had to use the construction stiff-traveler as the counterweight of the closure. Through measuring the index, we found this; construction method is feasible. In this paper, the construction technique, the theoretical foundation and the relevant observation data is comparatively detailed.
