百米以上双肢空心墩快速施工技术

On speedy construction technique of double-member hollow pier with a height of more than 100 meters

以某特大桥百米超高空心墩墩身施工为例,结合工程特点,介绍了液压爬模工艺流程,阐述了百米高墩泵送混凝土施工技术及现场施工组织措施,施工实践证明该施工方法取得良好效果,值得在同类工程中推广应用。

Taking the hundreds meter super-high hollow pier construction of some super-large bridge as the example,the paper introduces the craft procedure of the hydraulic climbing form by combining the engineering features,illustrates the hundreds meter high pier pumping concrete construction technique and the organization measures for the field construction,and proves by the construction practice that the construction method has better effect,so it can be further applied in similar projects.
