高速公路桥梁薄壁空心高墩控制技术

CONTROL TECHNIQUE FOR THIN WALL HOLLOW AND HIGH PIER OF EXPRESSWAY BRIDGE

结合工程建设实际情况,在山区高速公路桥梁高墩施工时,对桥梁高墩的模板选择、线位高程控制、钢筋绑扎以及混凝土浇筑技术措施进行有效控制,保证桥梁高墩的各项技术指标达到设计要求,符合规范规定,施工质量和工期满足合同要求,使桥梁高墩建成后满足工程建设及运营的安全要求。

Based on the practical construction of Yaohe River super-long expressway bridge in Shanxi province, effective control is realized in various technical measures, such as formwork selection, line elevation control, steel reinforcement binding and concrete placement, etc., during high pier construction of expressway bridge in mountainous area. It is guaranteed that various technical indices of the high pier satisfy the design requirements and relevant specifications, construction quality and schedule meet the contract requirements. The high pier of the expressway bridge satisfies the safety requirements for engineering construction and operation.
