Description
Technical Field
The invention belongs to the technical field of urban landscaping and river channel environment management construction, and mainly relates to a layout and construction method of an anti-erosion revetment structure of a curved river channel of an urban inland river.
Background
A curved river, which is widely present in urban rivers, has two typical features: a tortuous profile and the dynamic nature of the wriggling motion. In nature, a curved river often includes both concave and convex banks.
The impact force of water flow which flows in a curve in the river channel to the concave bank is large, the erosion is severe, and the damage to the bank vegetation and soil can be brought; on the other hand, the impact force on the convex bank is small, the water flow speed is slow, the effect on the bank vegetation and soil is represented as silting, silt can be increasingly deposited at the position, and the space is wider and wider. Therefore, in the municipal engineering of the curved river channel, the influence of the hydraulic evolution of the city river on the nature can be reduced to the minimum degree only by carrying out scientific planning and reasonable treatment according to different orientations of the river channel and local conditions according to the principles of hydraulic engineering, and the water is a resource which can be utilized by people.
The traditional river regulation technology relates to pollutant control of urban rivers (such as CN101293722A and CN101948213B), a bank embankment ecological landscape protection system (such as CN114108558A and CN202111410289), an urban river water quality improvement or optimization regulation and control method (CN110598936A, CN111333197A and CN111815498A) and the like, and aims at linear rivers, and aims at the river bank regulation of curved rivers and less technical documents of ecological construction, so that practical difficulties are brought to the ecological regulation and environmental protection of the urban river curved rivers. Especially, in recent years, people increasingly deepen natural protection and ecological friendly understanding, green water green mountains are created, the harmony of nature is pursued, the construction of ecological restoration type river banks with various functions of biodiversity protection and water and soil conservation as the main functions is established, and shoulder ecology, beautification, environmental protection and the like are more and more emphasized and advocated. On the premise of not influencing the natural ecological function of the river bank, the ecological environment protection and the creation of beautiful natural landscapes are both considered, the curved river bank which is easily influenced by human interference and water power is restored into a friendly zone with mutual dependence of water bodies and soil ecology and mutual benefit and symbiosis of water bodies and organisms, and the beautiful, pleasant, leisure, healthy and fostered waterfront landscape can be created while the clean water environment is created and maintained for the human.
