Method for replacing support of hollow slab type bridge
The invention discloses a method for replacing a support of a hollow slab type bridge with single span length smaller than 20 m. The method is characterized by comprising the steps of jacking displacement computing, equipment installation, jacking, and support treatment. Several jacks are adopted at the same time for jacking step by step, jacking displacement each time is 0.4-0.6 mm, and it is guaranteed that all the jacks have the same displacement during jacking, so that uniform stress is applied to all hollow slabs during jacking. The construction method is simple, construction speed is high, period is short, influence on a bridge structure is small, cost is low, and the replacement method is economical and reasonable; meanwhile, jacking is conducted in batches, transition area jacking is adopted, stress on a bridge deck is mild, the influence on the integrity of the bridge structure is small, and bridge deck cracking during jacking is prevented.
