Abstract
Under the protection of phase-Ⅲ upstream and downstream dry-season cofferdams,the downstream phase-Ⅲ allyear cofferdam in Tingzikou Water Control Project can be constructed in dry environment.Based on the actual condition,the construction method of downstream phase-Ⅲ all-year cofferdam is optimized.The pouring of cofferdam concrete core wall below normal low-water level is completed in dry season,and after flood season,the pumping of pit and the excavation of pit foundation is immediately conducted when the water level is below than the top of core wall.The construction method of phase-Ⅲ all-year cofferdam can speed up the construction and saves the costs on cofferdam filling material excavation and transportation.关键词
