Integrated pouring construction method for pier-beam-tower combined section of T-shaped pier extradosed cable-stayed bridge
The invention discloses an integrated pouring construction method for a pier-beam-tower combination section of a T-structure pier extradosed cable-stayed bridge. The pier-beam-tower combination section comprises a main beam No.0 block, a pier top section, a tower bottom section and a supporting section. The construction method comprises the steps that firstly, a T-shaped pier body is formed in a cast-in-place mode, and a pier top section is reserved to be not formed; secondly, the beam-tower combined reinforcement cage which is bound in advance is hoisted to the top of the T-shaped structure pier body; thirdly, the beam-tower combined reinforcement cage is fixedly connected with the reserved steel bars of the pier top section; fourthly, a pier top section side formwork, a beam-tower combination bottom formwork assembly and a beam-tower combination side formwork are erected, and the thickness of a steel bar protection layer is adjusted through an adjusting screw and an adjusting nut; and fifthly, the pier-beam-tower combination section is integrally formed through pouring. The pier-beam-tower combination section is formed by combining the main beam No.0 block, the pier top section, the tower bottom section and the supporting section, the pier-beam-tower combination section is constructed through integrated pouring, and the integrity and stability of the pier-beam-tower combination section of the extradosed cable-stayed bridge can be improved.
本发明公开了一种T构墩矮塔斜拉桥墩梁塔结合段一体式浇筑施工方法，墩梁塔结合段包括主梁0号块、墩顶段、塔底段和支撑段；该施工方法包括：一、现场浇筑成型T构墩主体，并预留墩顶段不成型；二、将预先绑扎完成的梁塔结合钢筋笼吊装至T构墩主体的顶部；三、将梁塔结合钢筋笼与墩顶段的预留钢筋固定连接；四、支设墩顶段侧模板、梁塔结合底模板组件和梁塔结合侧模板，并利用调节螺杆和调节螺母对钢筋保护层的厚度进行调整；五、一体式浇筑成型墩梁塔结合段。本发明通过将主梁0号块、墩顶段、塔底段和支撑段组合形成墩梁塔结合段，通过一体式浇筑施工墩梁塔结合段，能够提高矮塔斜拉桥墩梁塔结合段的整体性和稳定性。
