空心板桥加固维修施工工艺

随着交通运输业的快速发展,一些桥梁在运营多年后状况恶化,已经不能满足当前交通运输的要求,急需维修加固.通过以云南某预应力砼空心板桥为研究对象,综合分析该桥的病害情况,采用碳纤维筋高强聚合物砂浆加厚板底及补强、钢板加强横向联系、修补裂缝和更换支座等关键施工技术对该桥加固维修,达到加强空心板横向联系以及提高结构承载能力的目...

Construction Technology of Reinforcement and Maintenance of Hollow Slab Bridge

With the rapid development of the transportation industry,some bridges have deteriorated after many years of operation,can no longer meet the requirements of the current transportation,and are in urgent need of repair and reinforcement.Taking a prestressed concrete hollow slab bridge in Yunnan as the research object,the disease condition of the bridge is comprehensively analyzed,and carbon fiber reinforced high-strength polymer mortar is used to thicken the bottom of the slab and reinforce it,strengthen the lateral connection of the steel plate,repair the crack and replace the bearing.The construction technology reinforces and maintains the bridge to achieve the purpose of strengthening the horizontal connection of hollow slabs and improving the bearing capacity of the structure.The construction method is simple and clear,the construction period is short,it is effective and economical and reasonable,and it overcomes the defects of traditional reinforcement construction.
