The invention discloses a passenger transport hub ramp dismantling system and a construction method thereof, and belongs to the technical field of constructional engineering dismantling. The construction method comprises the steps that S1, a station front corridor is dismantled, and a traffic route is converted; s2, calculating the distance between the counterweight part of the to-be-dismantled steel box girder and the main road, selecting a support system, judging the steel box girder overturning risk levels of the first ramp and the second ramp, determining the dismantling sequence of the steel box girders according to the steel box girder overturning risk levels, and dismantling the steel box girders of the first ramp and the second ramp; and S3, the concrete box girder is supported by the third temporary supporting system, and the concrete box girder, the pier columns, the bridge abutment, the retaining wall and the approach bridge are sequentially dismantled through the excavator. According to the scheme, a proper supporting system is selected in combination with the actual environment of a project, and the problems that time and labor are consumed due to the adoption of a support method, steel stand columns are prone to deformation due to compression, and the recycling rate is low are solved.
本发明公开了建筑工程拆除技术领域的一种客运枢纽匝道拆除体系及其施工方法，施工方法包括：S1、拆除站前连廊，转换交通路线；S2、计算待拆除钢箱梁的配重部分与主道路的距离，选择支撑体系，判断第一匝道和第二匝道的钢箱梁翻转倾覆风险等级，根据钢箱梁翻转倾覆风险等级确定钢箱梁拆除顺序，再拆除第一匝道和第二匝道的钢箱梁；S3、第三临时支撑体系支撑混凝土箱梁，采用挖机依次拆除混凝土箱梁、墩柱、桥台、挡墙和引桥。本方案结合项目实际环境，选择合适的支撑体系，减少了采用支架法导致的耗时耗力，且钢立柱易受压变形，回收利用率较低的问题。
