Overhead section magnetic levitation turnout pushing connection precision control method
The invention discloses an overhead section magnetic levitation turnout pushing connection precision control method. The method comprises the steps that existing lines operate normally, construction preparation is conducted, a unified measurement control network is established, and linear measurement of the existing lines is conducted; turnout installation coordinates and elevation are obtained based on linear measurement data, turnout installation is completed, and static adjustment and track fine adjustment on a turnout beam are conducted; the existing line is stopped, the existing line beam is located after the turnout beam is located and before the turnout beam is pushed, the existing line track is subjected to sequential connection fine adjustment, and line shape monitoring and real-time debugging of the turnout beam body are carried out during pushing; based on the track butt joint error, precision regulation and control during beam falling are carried out in combination with the first control standard and the second control standard; a precision error is obtained, and line sequential connection after beam falling is carried out; and when the existing line recovers operation, the tracks at the front and rear sections of the turnout junction point are precisely monitored to ensure safe operation of the train. According to the method, one-time precision control is achieved, the construction efficiency is improved, and cost input is saved.
本发明公开了一种高架区间磁浮道岔顶推接驳精度控制方法，包括：既有线路正常运营，进行施工准备，建立统一的测量控制网，进行既有线路的线形测量；基于线形测量数据得到道岔安装坐标及高程，完成道岔安装，并进行静态调整和道岔梁上的轨道精调；既有线路停运，道岔梁落位后顶推前将既有线梁进行落位、对既有线轨道进行顺接精调，顶推时进行道岔梁梁体的线形监控和实时调试；基于轨道对接误差，结合第一控制标准和第二控制标准进行落梁时的精度调控；获取精度误差，进行落梁后的线路顺接；既有线路恢复运营，对道岔接驳点前后段的轨道进行精度监控，确保列车安全运营。本方法实现一次精度控制到位，提高了施工功效，节省了成本投入。
