Description

Technical Field

[0001] The present invention belongs to the technical field of Bailey bridges, and particularly relates to a quickly assembled Bailey bridge with an inclined adjustable bridge deck and a construction method thereof. Background Art

[0002] The Bailey bridge is made of high-strength steel and consists of lightweight standardized truss unit components, cross beams, longitudinal beams, bridge decks, bridge seats, and connectors, etc. It can be quickly assembled on-site with special installation equipment into a truss girder bridge suitable for various spans and loads. It is named as an assembled highway steel bridge in China. It is a kind of steel bridge, but it is not the same as a general steel bridge. The Bailey bridge is more typical, and its main feature is modularization, with more convenient and extensive applications. In the early days, the Bailey bridge was mainly used in the military, that is, military steel bridges. Now, in addition to being used as a war preparedness steel bridge, the Bailey bridge has been widely used in various fields such as disaster relief, traffic engineering, and dangerous bridge reinforcement.

[0003] When quickly assembling a Bailey bridge, it often encounters the situation that the heights on both sides of the river are inconsistent. When constructing the Bailey bridge, it is necessary to adjust the inclined surface of the Bailey bridge according to the heights on both sides of the river so that the Bailey bridge can be smoothly connected to both sides of the river. However, the existing Bailey bridge is constructed with a fixed lap joint and cannot adjust the inclination angle of the bridge deck of the Bailey bridge. In the face of the situation where the heights on both sides of the river are inconsistent, the existing Bailey bridge is not convenient to construct, which affects the construction and use of the Bailey bridge. Therefore, we propose a quickly assembled Bailey bridge with an inclined adjustable bridge deck and a construction method thereof. Summary of the Invention
