本文介绍了T型刚构桥水平转体法施工的工作原理、施工工艺,结合铜川市铁路立交桥所采用的水平转体法以及施工中的工艺特点,还对水平转动做了系统的分析与测试,根据经济效益得出了水平转体法的一系列优点:施工工艺简单,应用较广,能够节约投资,节省工期。其中,针对铜川市铁路立交桥在建设过程中遇到的各种问题也进行了全面分析,希望能对我国的T型刚构桥水平转体法施工技术有一定参考价值。
This paper introduces the working principle and construction technology of the T-type rigid frame horizontal swivel construction method, combined with the horizontal swivel method adopted by Tongchuan Railway overpass and the construction process characteristics, and also analyzes and tests the horizontal rotation systematically According to economic benefits, a series of advantages of horizontal swivel method are obtained: simple construction technology and wide application, which can save investment and save construction time. Among them, the various problems encountered in the process of Tongchuan railway overpass are also analyzed in a comprehensive way, hoping to have certain reference value for the construction technology of T-type rigid frame bridge in our country.
