As a new active reinforcement technology, prestressed carbon fiber plate reinforcement makes full use of the high strength and high elastic properties of carbon fiber, which can effectively improve the deformation of structural members and increase the bearing capacity of structures. This paper introduces the construction technology and key points of strengthening T-beam bridge with finished prestressed carbon fiber plate products developed and produced by Liuzhou Overem Machinery Co., LTD. The engineering practice shows that the strengthening construction method is effective, the construction process is simple, the period is short, the impact on the bridge floor traffic is small, the cost is economical, and it can be used for the design and construction of prestressed carbon fiber plate reinforcement of similar beam Bridges Provide reference.
