as an example, to ensure the normal operation of trains, the construction technology of dragging method is proposed
and introduced. The practice proves that the construction safety and efficiency can be ensured by the drag method in
the construction of overpass in busy railway lines. It can provide reference for similar project construction.:发重内海志机杂: busy railway line; overpass; dragging construction; hydraulic synchronization/u[?? ?7u ? 86’r?2????
