The Significance of Reinforcement and Reconstruction Technology of Bridge Superstructure

By analyzing the reinforcement and reconstruction technology of the bridge superstructure, it can help the construction personnel in the project better grasp the construction characteristics of the bridge superstructure and improve the overall construction quality of the bridge project. With the continuous increase in the number of bridge projects, the load-bearing capacity of the bridge superstructure is increasing. In order to ensure that the bridge superstructure is more stable, the construction personnel must analyze the external environmental factors in detail and adopt appropriate countermeasures to fundamentally reduce the occurrence of instability of the bridge superstructure and improve the traffic quality of vehicles.

Main Points of Application of Reinforcement and Reconstruction Technology for Bridge Superstructure

Reinforcement method of planting steel bars on bridge deck

In this bridge project, by using the reinforcement method of bridge deck planting reinforcement, the integrity of the bridge superstructure can be ensured, and the bearing capacity of the bridge superstructure can be improved.

Compared with the traditional bridge superstructure reinforcement and reconstruction technology, the construction process of the bridge deck reinforcement method is relatively simple, has less impact on the original bridge structure, and can ensure that the bearing capacity of the original bridge superstructure is effectively improved. In addition, the construction process of the bridge deck reinforcement method is more convenient. In the actual construction, the construction personnel can closely connect the old and new concrete structures, and implant a certain amount of steel bars in the connection parts, continuously shorten the concrete curing time and improve the bonding force of the concrete. The plant-reinforced adhesive is an environmentally friendly product, and has little pollution to the ecological environment.

Carbon fiber reinforcement method

Carbon fiber reinforcement methods are mainly divided into two types, namely carbon fiber cloth reinforcement and carbon fiber board reinforcement methods. Applying the carbon fiber reinforcement method to the reinforcement of the bridge superstructure can effectively improve the stability of the bridge superstructure and prevent the occurrence of structural instability. Compared with the traditional reinforcement technology of enlarged concrete section or bonded steel concrete, the carbon fiber reinforcement method has the characteristics of saving construction space, simple construction process, no on-site fixed facilities, and easy assurance of construction quality. In addition, the use of this construction method can greatly increase the service life of the building and reduce the cost of reinforcement.

Change the structural system reinforcement method

Applying the strengthening method of changing the structural system to the bridge project can effectively prevent large cracks in the upper structure of the bridge. Due to the limited bearing capacity of the bridge superstructure, once the external load is large, the bridge superstructure is prone to cracks, reducing the durability of the structure. Under normal circumstances, the length of the cracks in the superstructure of the bridge is about 50cm. By using the reinforcement method of changing the structural system, the occurrence of oblique cracks in the superstructure of the bridge can be effectively reduced, and large-area leakage at the junction of the old and new bridges can be prevented.

Girder and slab bridge bonding steel reinforcement method

By using the beam-slab bridge bonding steel reinforcement method, the construction strength of the weak parts of the bridge concrete structure can be improved, and the new and old concrete structures can be better combined to form a more stable whole. When there are many honeycombs in the upper structure of the bridge project, the use of beam-slab bridge bonding steel reinforcement method can effectively improve the quality of the upper structure concrete pouring.
