Quick pushing and transverse moving method for integral frame bridge
The invention discloses a quick pushing and transverse moving method for an integral frame bridge in existing rail way reconstruction, and a rail penetrates through the frame bridge. The method is characterized by comprising the steps that a sliding plate is constructed on one side of an existing rail way and a pushing back is constructed on the end of the sliding plate, the frame bridge is prefabricated on the sliding plate, and the top of a bottom plate of the frame bridge is roughly flush with the shoulder of the rail way; the pipe laying depth of pipelines on the two sides of a pushing and transverse moving area of the existing rail way is increased, and the pipe laying depth is larger than the bottom of the bottom plate of the frame bridge; a jack is installed at the back end of the frame bridge, lines and pathways of the existing rail way are dismantled, and the jack pushes and transversely moves the frame bridge; after the frame bridge is pushed and transversely moved to the position where an original rail way is removed, the lines and pathways of the existing rail way are restored in the normal position in the frame bridge. By the adoption of the form of the frame bridge, so the height of a bridge structure spanning the rail way is minimized, and a steel beam or a profiled-steel beam with the structure height in the same size is avoided; later operation and maintenance workloads of the rail way are lightened, and the requirements for safety, environment friendliness and energy conservation are satisfied.
