Construction method of high-speed rail turnout continuous beam
A construction method of a high-speed rail turnout continuous beam comprises the steps that the turnout continuous beam is segmented into a plurality of fin cutting single-line standard box beams, and the turnout continuous beam is constructed through the methods of prefabrication in a beam manufacturing field, beam moving through a beam lifter, beam transporting through a beam transporting vehicle, simple support erecting through a bridge girder erection machine, post-cast strip construction, hogging moment tensioning and simple support-to-continuous system conversion. The problem that cast-in-place of a support of the high-speed rail turnout continuous beam cannot be implemented under special conditions can be solved, and the continuous beam built through the method is better in stress.
一种高铁道岔连续梁的建造方法，将道岔连续梁分段为若干切翅单线标准箱梁，通过制梁场预制、提梁机移梁、运梁车运梁、架桥机简支架设、后浇带施工、负弯矩张拉、简支向连续体系转换的方法完成道岔连续梁的建造。本发明可以解决高铁道岔连续梁在特殊条件下支架现浇无法实施的难题，且该方法建造的连续梁受力更好。
