Frame-structure bridge jacking railway turnout reinforcing construction method
The invention discloses a frame-structure bridge jacking railway turnout reinforcing construction method. The method comprises the following steps of (1) conducting construction preparation, (2) reinforcing the cross beam, (3) fastening rail reinforcement, (4) reinforcing the longitudinal beams, and (5) checking and accepting. The geometric dimension of the whole turnout static inspection completely meets the requirements, and settlement observation point data analysis shows that the rigidity, the stability and the performance of each part of the reinforced turnout meet the safety use requirements. According to the construction method, the driving safety of the business line is guaranteed, the construction period is shortened while the resource investment is saved, and various plan indexesare realized successfully.
本发明公开了一种框构桥顶进铁路道岔加固施工方法，包括如下步骤：（1）、施工准备；（2）、横梁加固；（3）、扣轨加固；（4）、纵梁加固；（5）、检查验收。全程道岔静态检查几何尺寸完全符合要求，经沉降观测点数据分析显示加固后的道岔刚度、稳定性和各部位性能均满足安全使用要求。本发明施工保证了营业线行车安全，在节省资源投入的同时缩短了工期，圆满实现各项计划指标。
