CONSTRUCTION METHOD FOR OVERHEAD JACKING OF MULTI-TRACK EXISTING RAILWAY OF FRAME BRIDGE
Disclosed is a construction method for overhead jacking of a multi-track existing railway of a frame bridge. By means of construction modes of transition overhead construction-dewatering construction-formal overhead and two-end opposite jacking and middle cast-in-place, the risk caused by the groundwater level to a dig-hole pile is directly avoided. The overall construction scheme for the overpass pipe section follows the principle of segmented construction and line production, a jacking part of the overpass is firstly constructed, and after the jacking part is in place, a middle frame is cast in place, which guarantees not only the railway operation but also the construction period quality, and thus good economic benefits and construction guidance significance are achieved.
