Cable-free suspended casting method for front fulcrum hanging basket of side span cast-in-place section of cable-stayed bridge
The invention discloses a cable-stayed bridge side span cast-in-place section front fulcrum hanging basket cable-free suspended pouring method. The method comprises the following steps that S1, a bridge deck sliding beam longitudinally walks to the front end to be in lap joint with a supporting stand column along a main beam, and the rear end of the bridge deck sliding beam is anchored to a poured section of the main beam; s2, an arc padlock component at the front end of the bottom basket of the hanging basket and an operation platform are dismantled through a bridge floor truck crane; s3, the hanging basket bottom basket is pulled to the end of the transition pier cover beam by means of a self-walking hanging system and a shifter, after the hanging basket bottom basket is in place, the hanging basket bottom basket is lifted to enable the front end of the hanging basket bottom basket to be horizontally lapped on the horizontal plane of the transition pier cover beam, and the rear end of the hanging basket bottom basket is anchored and positioned on the poured section of the main beam; and S4, finally, a side span cast-in-place section is constructed, after the strength of the main beam reaches the standard, a stay cable of the side span cast-in-place section is hung to stretch the main beam at the position, and the method has the advantages that the safety risk is low, the labor cost is reduced, the construction period is greatly shortened, the conception is ingenious, and the structure is reasonable.
本发明公开了一种斜拉桥边跨现浇段前支点挂篮无索悬浇方法，包括以下步骤：步骤S1、桥面滑梁沿主梁纵向行走至前端搭接在支撑立柱上、后端锚固于主梁已浇筑节段上；步骤S2、利用桥面汽车吊机将挂篮底篮前端弧形挂锁构件及操作平台拆除；步骤S3、挂篮底篮借助自身走行吊挂系统和移位器牵引至过渡墩盖梁端头，到位后提升挂篮底篮使其前端水平搭接在过渡墩盖梁水平面，挂篮底篮后端锚固定位在主梁已浇筑节段上；步骤S4、最后施工边跨现浇段，待主梁强度达标后，挂设边跨现浇段的斜拉索对该处主梁进行张拉，具有安全风险低、降低人工成本、大幅缩短工期、构思精妙、结构合理等优点。
