基于PLC控制的桥梁同步顶升系统的应用

摘要

The paper indicates the key for the general jacking technique of bridges is to ensure the general synchronous jacking with its upper part,introduces the application of synchronous jacking system of bridges based on PLC control by combing with the engineering example,and illustrates the method has the outstanding advantages,including short period,low cost and others in the traffic interruption compared with the traditional support exchange method.%桥梁整体顶升技术的关键在于保证其上部结构的整体性同步顶升,结合工程实例,介绍了基于PLC控制的桥梁同步顶升技术在实际中的应用,与传统的支座更换方法相比,该方法具有中断交通时间短、工期短、造价低等突出的优点,值得推广应用。
