[0002] The hydraulic climbing formwork construction technology used in the construction of high bridge piers is one of the common construction methods in the construction of bridge piers. It has the characteristics of high safety performance, high quality controllability, and low requirements for construction resource allocation. In recent years, hydraulic pressure The application of climbing formwork in the construction of piers above 40m in China is becoming more and more common, and the scope of application is not limited to the pier body of highway bridges. It is used in the construction of ordinary railways and high-speed railways, but the hydraulic climbing formwork basically adopts mechanical or semi-mechanical construction. The basic electronic control operation of the system is performed manually, which exposes related problems such as unbalanced structural size control accuracy, high safety risk of human control, single system function and low integration
[0003] The 114m high pier of the Shilianghe Bridge on the Chongqing-Guizhou High-speed Railway is planned to be constructed using hydraulic climbing formwork, but the current hydraulic climbing formwork system often has the situation that the cylinders of the actuators are worn out or the performance is not uniform, which may easily cause the asynchrony of the various actuators , resulting in security concerns and risks
