Problems solved by technology

However, most of the plans are based on the maintenance of the original structure, without considering the transmission of the lateral force on the bridge deck to ensure the overall force. As a result, the bridge deck pavement is broken immediately after decoration, and it is in the cycle of repairing

Abstract

The invention discloses a repair structure for a damaged hollow slab girder bridge deck system and a construction method of the repair structure. The repair structure comprises rib plates and reinforcing steel bars, the rib plates are provided with through holes used for containing the reinforcing steel bars, the rib plates are transversely vertically arranged, and the reinforcing steel bars longitudinally penetrate through the rib plates. Compared with the prior art, the reinforcing steel bar and rib plate repair structure substitutes a reinforcing mesh structure in an original pavement layer, through combination of the reinforcing steel bars, the rib plates and concrete, a combination bridge deck slab resistant to shear and fatigue is formed, force is borne integrally, transverse shear capacity can be enhanced, and therefore the traffic passage requirements for large flow and heavy traffic currently are met.

Description

technical field [0001] The invention relates to the technical field of bridge deck repair, in particular to a damaged repair structure of a hollow slab girder deck system and a construction method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy and society, there are more and more vehicles on the road. Among these road vehicles, heavy-duty vehicles are in the majority. Due to the limitations of construction technology, the previous bridge design standards were low, and the bearing capacity was limited, making it difficult to meet the current bearing demand. Especially the bridges built with hollow slab girders are overwhelmed, and there are problems with the bridge deck pavement, especially the hinge joints. [0003] The hinge joints of these bridges are designed to be small, and their ability to transmit force laterally is limited. Once it is damaged, it loses the function of the hinge, causing the single beam to...
