The invention discloses a bridge floor replacing construction device. The bridge floor replacing construction device comprises crane guide rails 1 and a crane supporting frame 2. The crane supporting frame 2 is installed on bridge piers. The crane guide rails 1 are installed on the crane supporting frame 2. A crane 4 is installed on the crane guide rails 1. Guide wheels 46 are installed between the crane 4 and the crane guide rails 1. The bridge floor replacing construction device and a construction method thereof have the beneficial effects that the device and the construction method thereof are especially suitable for remote and mountainous regions, damaged bridges can be rapidly replaced, construction periods are shortened, cost is reduced, the practicability is high, and the device and the construction method thereof are suitable for application and popularization.
Description
technical field [0001] The invention relates to a bridge deck replacement construction device and a construction method thereof, belonging to the technical field of civil engineering construction. Background technique [0002] Bailey Bridge is the most widely used and most popular bridge in the world. It has the characteristics of simple structure, convenient transportation, fast erection and easy decomposition. At the same time, it has the advantages of large bearing capacity, strong structural rigidity and long fatigue life. It can form temporary bridges, emergency bridges and fixed bridges of various types and purposes according to the different spans of actual needs, and has the characteristics of few components, light weight and low cost. The original Bailey Army Bridge was designed by British engineers in 1938 at the beginning of World War II. During World War II, this kind of military steel bridge was widely used. After the war, many countries converted the Bailey s...
