为彻底纠正道岔群及前后与多条小半径曲线连接区段线岔轨道几何尺寸偏差,全面提高京沪下行无锡站内、外及其宁端道岔群线路、道岔、曲线轨道质量,保证动车组和旅客列车运行平稳。以线、岔、曲线精确定位测量为依据,优化曲线状态,充分发挥大机功能,采取直线激光拨道,曲线精确拨道,线、岔、曲线同步大机捣固,综合整治线、岔、曲线轨道几何偏差。
In order to completely correct the geometric deviation of the turnout orbit of the switchgear group and the connecting sections of a plurality of small radius curves and comprehensively improve the quality of the lines, turnouts and curvilinear orbits of the turnout groups inside and outside the Beijing-Shanghai descendent Wuxi Station and its Ningdu, and ensure that the EMUs and Passenger trains operate smoothly. With line, fork, curve accurate positioning measurement as the basis, optimize the curve state, give full play to large machine function, to take a straight line laser dial, the curve accurately dial, line, fork, curve synchronization large machine tamping, Curve track geometric deviation.
