液压自爬模在高墩大跨联体刚构空心墩施工中的应用

Application of Hydraulic Self-climbing Form in the Construction of Coupling Rigid Frame Bridge with Hollow High Pier and Long Span

以延延高速黄河特大桥薄壁空心高墩液压自爬模施工为例,详细阐述了液压自爬模施工操作流程、关键工序施工控制措施,并重点介绍了在高墩大跨联体刚构结构形式下对液压自爬模施工工艺改进的做法,对类似工程结构施工具有借鉴意义。

Taking the construction of hydraulic self-climbing form for the hollow thin-walled high piers of Yellow River Bridge in Yan＇ an-Yanchang Expressway as an example, this paper expounded the construction operation process and key working procedure construction control measures of hydraulic self-climbing form, focusing on improving the construction technology of hydraulic self-climbing form under the form of coupling rigid frame bridge with high pier and long span. It could be referred by similar engineering structure construction.
