With the continuous advancement of national construction, the number of cross-line Bridges and cross-river Bridges is also increasing. However, due to the influence of many factors such as terrain location, climate and navigation, the common erection equipment is difficult to meet the construction requirements. The device required by this construction method is a set of a new generation of bridge pushing construction device, which integrates pushing, translation and lateral correction. The construction method is multi-point synchronous pushing beam, the sliding surface is installed in the device, and the sliding surface is not at the bottom of the main beam, which can effectively ensure the contact between the pushing device and the main structure, improve the force of the main structure, and almost affect the main structure Zero damage. In this paper, the control strategy and design algorithm of the control system of the device are studied, and some control theories and research directions about the walking type push are described in combination with the actual working conditions.
