Suspension bridge stiffening beam hoisting method
The invention discloses a suspension bridge stiffening beam hoisting method which comprises the following steps: presetting hoisting openings, setting sections S4-S6 as the hoisting openings, and hoisting sections S30 and S29 as well as sections S30'and S29 'below mounting positions through cables; middle hoisting is conducted, specifically, middle stiffening beams are hoisted and installed, and after the S0 section stiffening beams and the S0 'section stiffening beams are connected, the remaining stiffening beams are hoisted alternately; a main body is hoisted, specifically, the S7 section of stiffening beam is hoisted firstly, then the S8 section of stiffening beam is hoisted, then the S9-S28 sections of stiffening beams are hoisted and installed, the prepared S29 section of stiffening beam and the S29'section of stiffening beam are hoisted in sequence through a cable crane and connected with the corresponding S28 section of stiffening beam and the S28 'section of stiffening beam, and then the corresponding S30 section of stiffening beam and S30' section of stiffening beam are gradually loosened and connected with the corresponding S29 section of stiffening beam and S29 'section of stiffening beam; and finally, the stiffening beams of the S4 section, the S6 section and the S6 section are hoisted.
本发明公开了一种悬索桥加劲梁吊装方法，包括下列步骤：预设起吊口，S4‑S6段设置为起吊口，然后将S30和S29和S30'和S29'段加劲梁通过缆索吊运至安装位置之下；中部吊装，将中部加劲梁吊装安装，待S0段加劲梁和S0'段加劲梁连接后，交替吊装剩余的加劲梁；主体吊装，先吊装S7段加劲梁，再吊装S8段加劲梁，此后吊装安装S9‑S28段加劲梁，缆索吊先后吊装准备好的S29段加劲梁和S29'段加劲梁，并与对应的S28段加劲梁和S28'段加劲梁连接，然后逐步放松对应的S30段加劲梁和S30'段加劲梁，与对应的S29段加劲梁和S29'段加劲梁连接；起吊口吊装，最后吊装S4～S6段的加劲梁。
