| Abstract: | Combining with Xinmintan bridge engineering in No.333 provincial highway of Yangzhou city,this paper introduces the comprehensive application of non-disperible underwater concrete and grouting technology in deep water in bottom sealing of bridge cofferdam. The mix design and construction control of non-disperible underwater conrete are also analyzed, the paper could provide reference for similar defect treatment of bridge foundation construction in deep water. |
