Abstract

The invention discloses an intelligent highway concrete bridge expansion joint transition area repairing structure and a construction method thereof. The repairing structure comprises an analysis system capable of obtaining repairing data through analysis; a repairing groove; a repairing cage which is a latticed square frame formed by welding reinforcing steel bars in a criss-cross manner and is provided with at least two layers; anchor rods which are arranged on the side walls of the square frame; repair bags in the square frame; a supporting layer arranged above the repairing cage; and a surface layer which is arranged above the supporting layer, and comprises a cement mortar layer and a steel wire mesh layer arranged in the cement mortar layer. The shape of the repair bags after being filled with light concrete mortar is matched with each layer of the square frame, and anchor rods located at the two sides of the repair bags are nailed into blind holes formed in the side wall of therepair groove. Repairing data are flexibly customized according to the conditions of all bridges, so that the repairing structure is more suitable for the corresponding bridges, and the repairing structure is high in breaking strength, excellent in impact resistance and high in interface bonding strength.

Description

technical field [0001] The invention relates to the technical field of bridge repair, in particular to an intelligent highway concrete bridge expansion joint transition area repair structure and a construction method thereof. Background technique [0002] Nowadays, the number of cars is getting higher and higher. With the continuous increase of vehicle traffic, vehicle load level driving speed and over-limit and overload conditions, the requirements for driving comfort and safety of road surfaces and bridge structures are constantly increasing. As an important part of the bridge superstructure, the bridge expansion device's quality and durability have an important impact on the service life of the bridge. Therefore, people pay more and more attention to the bridge expansion joints, and a variety of The bridge expansion joint structure is used to improve the use effect and comfort of the expansion joint. However, the degree of attention to the bridge expansion joint transitio...
