Technical Field

[0001] This invention belongs to the field of civil engineering construction technology and relates to a sightseeing and leisure bridge structure that facilitates the widening of old bridges. Background Technology

[0002] As we all know, a bridge generally refers to a structure built across rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also been extended to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. Bridges are an indispensable part of the road system.

[0003] After a certain number of years of use, the load-bearing capacity of bridges will decrease, and they will no longer be able to support heavy weights. With social development, the number of private vehicles is increasing, and old bridges with reduced load-bearing capacity need to be renovated. The traditional renovation method is to demolish the old bridge and rebuild a new one, which involves large investment costs and does not make effective use of the old bridge. In view of the above problems, this invention proposes a sightseeing and leisure bridge structure that facilitates the widening of old bridges. Summary of the Invention
