摘要
以昌赣铁路客运专线中的动走B线简支梁拆除施工为实例,对邻近营业线简支梁吊落拆除技术进行研究,分别提出双吊机协同拆除简支梁及三吊机协同拆除简支梁施工技术,并重点分析梁片吊落工艺流程及关键施工参数。通过在工程中的成功应用,验证了该施工技术的合理性及可靠性,可为类似吊梁施工提供借鉴。
The removal of simple supported beams of the operating railway line B of Chang-gan Railway passenger special line is taken as an example in this paper,and the removal technology of simple supported beams of adjacent operating railways is studied,The construction technology of collaborative removal of simple supported beams by double crane and collaborative removal of simple supported beams by three cranes is proposed respectively,and the process flow and key construction parameters of beam sheet lifting are analyzed.Through the successful application in the project,the rationality and reliability of the construction technology are verified,which can provide reference for similar hanging beam construction.
