| Abstract: | The NO. 5 pier of Zongmugou Extra large Bridge of Huanghanhou Railway is designed to be the new column plate hollow pier. The longitudinal and transverse structure of pier in the shape of 1.6 parabola is made of 4 non-uniform upright pests and 3 transbeams with 105 m in height, and this is the first time in the railway construction. The paper introduces the key technology of hydraulic climbing formwork scaffolding system and the bracket method for cast-in-situ construction of the new column plate hollow superhigh pier with 3 prestressed transbeams, which can provide references for the similar projects. |
