High-safety bridge mounting and dismounting construction method
The invention relates to the technical field of bridge construction, and discloses a high-safety bridge mounting and dismounting construction method. The method comprises the following steps: erectinga stable bracket on a lower side of a bridge section of a concrete bridge to be dismantled; fixing an anti-collision wall of the bridge section of the concrete bridge to be dismantled to a bridge deck through a chain hoist, and then cutting the anti-collision wall; after the anti-collision wall is cut, drilling at least four hoisting holes in each beam plate needing to be dismounted, and making the anti-collision wall be fixedly connected with a bridge girder erection machine through a traction steel rope so that the whole beam plate is in a hoisting state, and then carrying out cutting operation; correspondingly connecting a lifting hook of lifting equipment with a steel structure bridge assembly, and lifting the steel structure bridge assembly to the safety support through the lifting equipment; and installing and building the steel structure bridge assembly, and completing building of a new bridge section. The high-safety bridge mounting and dismounting construction method has advantages that the safety in bridge mounting and dismounting construction is greatly improved, procedures are rigorous and orderly, and construction safety of workers can be well guaranteed.
本发明涉及桥梁施工技术领域，且公开了一种安全性高的桥梁安拆施工方法，在待拆除的混凝土桥梁桥段的下侧搭设稳固支架；将待拆除混凝土桥梁桥段的防撞墙用链条葫芦将其固定在桥面上，再进行防撞墙的切割工作；防撞墙切割完成后在每块需要拆除的梁板上至少钻上四个吊装孔，并通过牵拉钢绳与架桥机固定连接在一起，使得整段梁板处于吊装状态再进行切割操作；将起吊设备的吊钩对应连接钢结构桥梁组件，使用起吊设备将钢结构桥梁组件吊装在安全支架上；对钢结构桥梁组件进行安装搭建，完成新桥梁段的搭建。该安全性高的桥梁安拆施工方法，具备极大的提高了桥梁安拆施工中的安全性，工序严谨有序，能够很好的保证工作人员的施工安全的优点。
