板梁桥小铰缝预养护技术研究

Study on pre-maintenance technology of small hinge joints of slab-girder bridge

从实际工作出发,通过对现有的板梁桥小铰缝病害产生的原因及发展趋势进行调查,研究铰缝预养护施工技术的可行性及实施效果,并依托工程以实施应用并进行成效分析,明确预养护技术应用的实施范围及效果,达到提高桥梁整体强度、改善施工环境、降低维修成本、减少施工对交通和公众影响的目的,提高施工安全系数。

ct:Based on the actual wor.k,this paper investigates the causes and development trend of the existing disease of small hinge joints of slab-girder bridge,and studies the feasibility and implementation effect of the construction technology of pre-maintenance of hinge joints.Relying on the project to implement the application and effectiveness analysis,clear the scope and effect of the application of pre-maintenance technology,to improve the overall strength of the bridge,improve the construction environment,reduce maintenance costs,reduce the impact of construction on traffic and the public,and improve the construction safety factor.
