Description

Technical Field

[0001] The invention relates to the technical field of municipal buildings, and in particular to a drainage ditch device for cities to cope with extremely heavy rainstorms. Background Art

[0002] With the continuous acceleration of urbanization, the river space in many urban built-up areas has been continuously squeezed. Although the conversion of the original open ditch into underground channel has expanded the urban construction land, it has reduced the water collection capacity of the underground channel river, increased the flood risk of municipal buildings, and posed a serious threat to urban operations and residents' lives. The cement cover slabs laid in the traditional ditch transformation are helpful to facilitate the construction of urban roads and residents' travel. However, in response to urban flood risks and disaster prevention and control under extreme rainstorms, the flood discharge surface will be weakened, hindering the flow of water in the river and failing to meet the requirements of safe flood discharge.

[0003] Therefore, it is very necessary to provide a ditch cover that can adapt to the change of ditch water volume in time to meet the flood discharge requirements in real time, does not affect the urban ground function, and is easy to operate and reusable. Summary of the invention
