Method for maintaining bridge pier overhaul platform
The invention belongs to the field of repair and reinforcement, and relates to a method for maintaining a bridge pier maintenance platform, which comprises the following steps: S1, rust removal: carrying out rust removal treatment on the steel structure surface of a damaged part on the bridge pier maintenance platform; s2, reinforcing nails are fixed, and the reinforcing nails are welded to the surfaces of the two sides of the fracture position of the crack cavity of the damaged part; s3, primary reinforcement is conducted, specifically, iron wires are bound to the reinforcing nails on the two sides of the fractured position of the crack cavity of the damaged part; and S4, secondary reinforcement is conducted, specifically, the damaged part is wrapped with modified ultra-high-performance concrete, and secondary reinforcement protection is conducted on the damaged part through the modified ultra-high-performance concrete. According to the maintenance method adopting the modified ultra-high performance concrete as a renovation maintenance material, the connection strength of the whole structure of the damaged part can be guaranteed, the situation that the maintenance platform is repeatedly maintained due to the rusting problem can be avoided, new steel does not need to replace waste steel, the maintenance cost is reduced, and a large amount of manpower and material resources are saved.
本发明属于修补加固领域，涉及维修桥墩检修平台的方法,包括以下步骤：S1：除锈，对桥墩检修平台上受损部位钢结构表面进行除锈处理；S2：固定加强钉，在受损部件裂缝空洞折断处两侧的表面上均焊接加强钉；S3：一次加固，采用铁丝捆绑到受损部件裂缝空洞折断处两侧的加强钉上；S4：二次加固，在受损部件上包裹改性超高性能混凝土，利用改性超高性能混凝土对受损部件进行二次加固保护。本发明采用改性超高性能混凝土作为翻新维修材料的维修方法，能够保证受损部件整体结构的连接强度，还能够避免检修平台因为锈蚀问题出现反复维修的情况，无需用新的钢材替换废旧钢材，降低了维修成本，节约了大量的人力物力。
