Abstract
The invention relates to a quick replacement method of an overpass bridge section. The method includes the steps that (1) the damaged bridge section is detached, wherein a transportation and supporting integrated vehicle runs to one side of the damaged bridge section and enters a position under a position between two supporting piers of the damaged bridge section; (2) locking of the damaged bridge section and adjacent bridge sections is eliminated, wherein the transportation and supporting integrated vehicle jacks the damaged bridge section by means of a lifting system of the transportation and supporting integrated vehicle so that the damaged bridge section can be detached from the supporting piers; (3) the transportation and supporting integrated vehicle transports the damaged bridge section, retreats to an access road and is lowered to an initial position by means of the lifting system and leaves the site; (4) a new bridge section is installed, wherein the process is reverse to that of the detachment of the damaged bridge section. According to the quick replacement method, quick detachment and installation can be achieved in a one-shot mode, detachment and installation of the overpass bridge section of an existing bridge can be finished over one night, traffic of existing roads is not influenced in the day, great changes are brought for urban overhead bridge construction in which old bridge sections are replaced with new bridge sections, quick bridge renovation process is achieved in a real sense, influences on urban traffic are reduced to the largest degree, and the quick replacement method has remarkable social benefits.
