文章针对平胜大桥主塔高度高、体积大、施工难度大的特点,介绍了该桥主塔上下横梁灌注支架、塔柱爬模爬架的设计要点以及相关施工技术。但通过采用常规、成熟的施工方案进行设计与施工,为主塔顺利按工期要求完成施工提供了有利条件,同时也减小了施工风险,从而有利于节约成本,为类似桥梁主塔的设计、施工积累了宝贵的经验。 According to the characteristics of the main tower of Pingsheng Bridge, such as high height, large volume and large construction difficulty, this paper introduces the design essentials and related construction techniques of perfusion bracket and tower crawler climbing frame of the upper and lower pylons of the bridge. However, the design and construction by adopting the conventional and mature construction schemes provide favorable conditions for the completion of the construction of the main tower smoothly according to the construction requirements, and also reduce the construction risk, thereby contributing to cost savings. For the design of similar main pylons, Construction has accumulated valuable experience.
