PLC液压控制系统在桥梁整体同步顶升中的应用

摘要

For how the new bridge dock with the old bridge, especially for the bridge just put into use for a little time, it should consider from many aspects, such as the economic, environmental protection, transportation, use value safety. The reliability of the whole bridge will directly affect the safety and durability of the bridge, PLC hydraulic control system can effectively solve the synchronous displacement problems in jack-up and landing of the bridge superstructure and ensure the integrity of bridges.%新建桥梁与原有旧桥梁的对接如何进行，尤其是对刚投入使用不久的桥梁改造，应从经济、环保、交通、使用价值安全等多方面考虑。桥梁整体可靠程度将直接影响桥梁结构的安全度和耐久性，PLC液压控制系统能够有效解决桥梁上部结构在顶升、降落过程中同步位移的难题，保证桥梁的整体性。
