Description

Technical Field

[0001] The invention belongs to the field of water conservancy projects, and in particular relates to a river bank sluice bridge connecting a river beach. Background Art

[0002] As part of the riverside belt, the river beach is mainly formed by silt deposition. It has flood control and landscape functions. It also serves as the opening space of the riverside city, plays a role in improving the urban landscape and carrying historical and cultural connotations. In recent years, with the development of tourism and catering industries, the construction of river beaches can also drive the economic development of surrounding areas. In this context, local governments have strengthened their attention and investment in river beach construction to promote the sustainable development of river beaches.

[0003] Traditional river beaches are beach areas outside the embankment, and usually have no access to the river. Pedestrians can only enter and exit through the few gates on the embankment, which is extremely inconvenient. Due to the natural barrier of the embankment, the river beach and the city separated by the embankment are like two different worlds. To develop and transform the river beach, the first task is to open up the embankment channel so that pedestrians and vehicles can enter and exit conveniently; at the same time, the setting of the channel cannot affect the flood control function of the embankment, and the channel can be effectively closed during the flood season to protect people's lives and property.

[0004] To sum up, it is extremely necessary to build a sluice bridge on the embankment that has both traffic and flood control functions. Summary of the invention
