Any bridge becomes old during its lifetime. Bridges constructed in the early days, due to the limited understanding of the function of paving and diseases at that time, often have problems such as small reinforcement, too fine diameter of steel bars, and unfastened continuity of the interface between paving and load-bearing members. Since bridges are not only affected by the natural environment (such as atmospheric corrosion, temperature, humidity changes, etc.), but also by the use of the environment, it is difficult to avoid damage phenomena. This makes the reinforcement and renovation of old bridges has become inevitable.
The necessity of bridge reinforcement and repair is mainly reflected in the following aspects:
1. Ensure safety: with the growth of the use of time, the bridge may have structural damage, cracks, corrosion and other problems, all of which will affect the safety of the bridge. Through reinforcement and repair, potential safety hazards can be eliminated to ensure the carrying capacity and stability of the bridge, and safeguard the safety of pedestrians and vehicles.
2. Extend the service life: timely reinforcement repair can delay the aging and damage of the bridge, extend its service life, avoid premature demolition and reconstruction, and save money and resources.
3. Adapt to traffic demand: With the increase of traffic flow and changes in load, the original bridge may not be able to meet the current traffic demand. Reinforcement and repair can improve the carrying capacity of the bridge and adapt to the development of transportation.
4. Ensure normal operation: Bridges are an important part of transportation, and if they fail or are damaged, it will lead to interruption of transportation, which will bring negative impacts to the economy and society. Regular reinforcement and maintenance can ensure the normal operation of bridges and reduce the incidence of failure.
5. Protecting the environment: Compared with new bridges, strengthening and repairing has less impact on the environment. It can reduce the generation of construction waste and damage to the surrounding environment, which is in line with the requirements of sustainable development.
6. Improvement of economic benefits: the cost of strengthening and repairing is usually lower than that of new bridges, and it can extend the service life of bridges, which has better economic benefits in the long run.
Bridge reinforcement and repair is an important measure to ensure the safe, reliable and economic operation of bridges, which is of great significance for ensuring smooth transportation, promoting economic development and social stability.
