The characteristics of jiefang bridge's transformation:
The transformation of jiefang bridge is divided into three steps. After a long period of inspection, it is found that the main diseases of jiefang bridge include: internal corrosion of gear seat beam in opening system; The lower edge of the tooth seat beam is seriously corroded, the angle steel is corroded, and the part below the web plate is corroded; The tooth groove above the tooth seat beam is corroded, and the thickness of the rust layer is about 20 mm
In addition to the rust expansion between plates and the corrosion at the top, there is still a lot of water in the middle of the arc beam, and the plates are seriously corroded. It is precisely because these diseases have not been cured, so the opening function of jiefang bridge has been lost for more than 30 years, and the last opening was at 1973.
In order to maintain the historical features of the old bridge, jiefang bridge will carry out renovation and renovation according to the principle of "repairing the old as before", and no new design elements will be added. During the reconstruction, all the components on the bridge were repaired and maintained; Restore the original opening function; Repave the bridge deck. During the renovation, the bridge deck in jiefang bridge will not be widened.
After the renovation, jiefang bridge will resume the "Shierzel" opening function, that is, the deck will be opened upward from the middle to both sides until it is almost perpendicular to the original deck, and the Shuang Ye will move backward to ensure the smooth passage of the cruise ship.
