Pi-shaped section prestressed concrete cable-stayed bridge girder hanging basket construction method
The invention relates to the related technical field of bridge construction, in particular to a Pi-shaped section prestressed concrete cable-stayed bridge girder hanging basket construction method which comprises the steps of a main bridge full framing cast-in-place construction process, a hanging cable construction process, a hanging basket splicing process and a hanging basket prepressing process. The hanging basket is composed of a bearing platform, a guy rope system, a walking system, a positioning system, an anchoring system, an operation platform, an embedded part system and the like. The tensioning mechanism is composed of the tensioning rod, the adjusting piece, the base plate, the screwing base and the auxiliary disassembling piece in a combined mode, the clamping groove is formed in the side wall of the tensioning rod, and the adjusting piece is composed of the threaded pipe and the supporting base in a combined mode; and the clamping assembly composed of the moving block, the clamping block and the supporting spring is arranged in the mounting groove in the supporting seat, so that the clamping block abuts against the interior of the clamping groove through the supporting effect of the supporting spring, and the positioning stability of the adjusting piece is effectively guaranteed.
本发明涉及桥梁施工相关技术领域，具体为一种π型截面预应力混凝土斜拉桥主梁挂篮施工方法，π型截面预应力混凝土斜拉桥主梁挂篮施工方法包含：主桥满堂支架现浇施工过程、挂索施工过程、挂蓝拼装过程、挂蓝预压过程，其挂篮由承载平台、牵索系统、行走系统、定位系统、锚固系统、操作平台及预埋件系统等组成；通过将张拉机构设置成由张拉杆、调节件、垫板、旋拧座和辅助拆卸件组合构成，并在张拉杆的侧壁上开设卡合槽，并将调节件设置成由螺纹管和支撑座组合构成，并在支撑座上的安装槽之中设置由移动块、卡合块和支撑弹簧组合构成的卡合组件，从而通过支撑弹簧的支撑作用，以让卡合块抵在卡合槽之中，从而有效保证调节件的定位稳定性。
