Muzhou Bridge is a large bridge spanning the Muzhou Waterway, with a length of 702.36 meters and a width of 25 meters. The total investment is approximately 66.12 million yuan, making it an important part of the newly constructed first-class highway from Xinhui to Zhongshan.
In 2012, our company provided an intelligent continuous jack synchronization system for this bridge. After multiple technical exchanges between the Jingke Hydraulic Technology team and engineering technicians, and considering the specific characteristics of the bridge, we adopted an intelligent continuous jack synchronization system based on hydraulic transmission, computer control, and fieldbus technology. This system utilized automatic continuous jacking jacks, automatic continuous jacking pump stations, and a PLC master control console. The master control console centrally managed each pump station and jack to ensure that all jacks started, applied force, and operated synchronously. A jacking platform was set up on the shore side, and multiple temporary piers were established along the bridge toward the opposite shore. On both sides of each temporary pier, a set of jacking devices was installed. Each jacking device was powered by an independent hydraulic pump station and controlled at the front end by an independent sub-controller, which communicated with the main controller via fieldbus. Under the unified control of the computer system, the jacking devices adjusted the height of each pier and comprehensively controlled the jacking force and speed based on the support force, ensuring that the jacking force of each pier corresponded to its friction force.
2012年我公司为该桥梁提供智能连续千斤顶同步系统。经过精科液压技术团队与工程技术人员经过多次技术交流结合大桥特点采用基于液压传动、计算机控制及现场总线技术---智能连续千斤顶同步系统，通过采用自动连续顶推千斤顶，自动连续顶推泵站及PLC主控台，主控台对各泵站及千斤顶进行集中控制，保证所有千斤顶启动、施力、运行同步。在岸侧设置顶推平台、顺桥至对岸设置多个临时桥墩，在每个临时墩左右两侧各安置一套顶推装置。各个顶推装置有独立的液压泵站提供动力、由独立的分控制器实施前端控制，并通过现场总线与主控制器通讯。顶推装置在计算机系统的同一控制下，调节各个支墩的高度、根据支撑力的大小实现顶推力和速度的综合控制，确保各个支墩的顶推力与其摩擦力相应。
