摘要
连续梁转体施工过程中转体合龙精确对中有多种控制措施,蒙古营印河特大桥通过采用激光投线仪对中控制技术,可以在无须测量人员上下桥的情况下,实现转体梁的精确对中及姿态调整。同时在转体过程中,通过采用传统对中控制校验,验证了该新型控制措施的可行性,同时多种控制措施的结合使用进一步保证转体的对中控制精度。
There are various measures for precision closure position in rotation construction of continuous girder, closure position and attitude adjustment in rotation construction of continuous girder can be completed without manually operation by position control technology of laser line throwing apparatus in construction of Mongol Camp Indian River Bridge. At the same time, the new control measures are proved to be feasible by traditional control measures in rotation construction, which ensure precision closure position by the combined use of various control measures.
