Application of ZLD automatic continuous top pushing system in the construction of corrugated steel web PC composite beam bridge

Taking the first application of the top pushing construction method in the Changzhuang Reservoir section of the Luohai Road Expressway project in Zhengzhou City as the background, this paper introduces the design of the construction scheme, related construction technology and key points of the ZLD automatic continuous top pushing system applied to the top pushing of corrugated steel web PC composite beam bridge. Engineering practice shows its superiority in synchronous control, high degree of automation, and flexible construction. It can adjust the top pushing force in real time according to the horizontal reaction force and deformation at the top of the pier, improving the efficiency and safety reliability of top pushing engineering construction, and has a wide application prospect.
