Construction method for dismantling non-solid box girder of ramp
The invention provides a construction method for dismantling a non-solid box girder of a ramp. The construction method for dismantling the non-solid box girder of the ramp comprises the steps that S1, a full framing is erected below the non-solid box girder; s2, a ramp surface pavement layer is broken and removed; s3, the anti-collision wall is cut and dismantled; and S4, the non-solid box girder is divided into three parts, the three parts are cut in batches, and a truck crane is adopted for hoisting and removing. The non-solid box girder is divided into three parts, the three parts are cut in batches, it is guaranteed that the box girder cannot slip in the transverse direction and the vertical direction when being dismantled, the weight of a single cut block can be greatly reduced, the mechanical configuration requirement is lowered, the influence of site restriction is reduced, and cost is saved.
本发明提供了一种拆除匝道非实心箱梁的施工方法，所述拆除匝道非实心箱梁的施工方法包括：S1：在非实心箱梁下方搭设满堂支架；S2：进行匝道面铺装层破除；S3：切割并拆除防撞墙；S4：将非实心箱梁划分为三部分，对三部分分批进行切割，并采用汽车吊进行吊运移除。通过将非实心箱梁划分为三部分，对三部分分批进行切割，确保了箱梁在拆除时不会在横向及竖向发生滑移，还能大幅降低切割分块单块的重量，降低机械配置要求，减少场地制约的影响并节约成本。
