cement paste jacking construction techniques after the bearing plates of interconnections between the steel

Zhang Ping,Jiang Jian,Dong Qinjun,Cai Wei,Liu Ying

Strategic Study of CAE 2010, Volume 12, Issue 4,   Pages 53-57

Abstract:

Taizhou Bridge is a three-tower, two-span suspension bridge with the herringbone middle tower in the longitudinal direction. The two oblique legs are anchored by screw bolts at the top of the concrete cap and the pressure plates of the D0 segment transmit pressure to the concrete cap. The top surface of concrete has bi-directional slope degrees. The space needed for concrete cement paste jacking is reserved at the top of the tower cap. After the segment D0 is installed, the concrete mud with high strength and no shrinkage is pressed into the space to form the supporting surface of the pressure plates. This paper briefly describes the concrete cement paste jacking techniques used in the construction procedure.

Keywords： high strength     self-leveling     no shrinkage     post-grouting     technology
