This article expounds reconstruction project of sluice outward at Changxing Island Xinkai Port. According to the most unfavorable load, the article checks the security and stability of the bent, and then designs the support system of bent. In order to form ensemble, it can be hoist symmetrical y one by one, then welding. In order to form the whole arched girder, the pumping concrete can be fil ed to symmetrical jacking in the arch rib, and then the bent support system can be removed final y.
