Abstract

The invention relates to a bailey beam construction trestle expansion joint system and a construction method, and the system comprises at least two bailey beams, the two bailey beams are arranged at intervals, and a gap is formed between the two bailey beams; the two bridge deck slabs are respectively arranged on the corresponding bailey beams, and a bridge deck pavement layer is arranged on the top surface of each bridge deck slab; the cover plate is located between the two bridge deck pavement layers, and the cover plate is laid above the gap; one end parts of the two connecting rods are respectively hinged with the corresponding bailey beams, the other end parts of the two connecting rods are respectively hinged with the cover plate, and the top surface of the cover plate is flush with the top surface of the bridge deck pavement layer, so that when a vehicle passes, the vehicle is not easy to jump, and when the vehicle jumps, the cover plate is not easy to fall off. The cover plate can slightly move left and right in the horizontal direction, and the cover plate is not prone to damage or deformation, so that the structure is not prone to bumping, and the cover plate is not prone to damage or deformation.

Description

technical field [0001] The invention relates to the technical field of bridge engineering construction, in particular to an expansion joint system and a construction method of a trestle bridge in Bailey beam construction. Background technique [0002] At present, in the construction of Bailey beam trestle bridge, it is usually necessary to set expansion joints due to the influence of terrain and longitudinal slope. [0003] However, Bailey girder trestle usually bears the load of heavy construction machinery such as concrete tank trucks and muck trucks, and the steel plate structure protrudes above the bridge deck. It is easy to be damaged or deformed when it is impacted by a jumping car, which affects traffic passage and driving safety. [0004] Therefore, we provide an expansion joint system for Bailey beam construction trestle bridges, which solves the above problems raised in the background art.
