Description
Technical Field
The utility model relates to the technical field of river bank protection, in particular to a river step type bank protection suitable for reservoir regulation and storage.
Background
Cities are large populated areas formed by the gathering of non-agricultural industries and non-agricultural populations. Urban rivers typically include a main river that is crossed and a side stream that flows into the main river. The main river has three main functions of water safety, water resource and water traffic which are traditionally considered, and also has four auxiliary functions of water environment, water ecology, water landscape and water culture which reflect the harmonious relationship between human and nature. For river reach of reservoir change water return area, the city river takes flood control as the main, and bank protection engineering is an important governing measure for city river flood control.
In recent years, with the development of cities, all relevant departments put forward new requirements on bank protection projects, so that flood control and traffic are required, the projects are required to have landscape greening, hydrophilicity and other functions, and meanwhile, the situation that the reservoir capacity of the reservoir is invaded is not allowed to occur due to the enhancement of reservoir area management. Therefore, multiple targets such as flood control, traffic, bank protection, city construction, river-following greening, hydrophilicity and the like are more considered in engineering design, a reservoir water storage operation mode is considered, engineering excavation and filling are reduced, construction is convenient as much as possible, and the combination of the arrangement of the dike lines and the characteristics of the water regime of the engineering section and the municipal construction needs to take smooth river channel flood and smooth water flow lines as key points. In order to further improve the urban traffic environment, the existing urban prosecution encourages and guides social strength to actively participate in investment construction operation of public parking lots, the problem of 'difficult parking' in urban areas is effectively relieved, and project owners utilize underground spaces of park greenbelts, protective greenbelts, squares, roads and the like and spaces under viaducts to construct the public parking lots.
In river reach with large changes of water and sand conditions, such as under dam or reservoir change water return areas, the trend change of erosion and deposition and the change of characteristic flow bring changes to characteristic water level, flood control planning is often biased to safety, so that the design water level of the dike engineering is high, the dike is 'wall-sharing', and the pressure is brought to engineering cost control and general appearance of rivers along the river. Meanwhile, the river-adjacent land of the Yangtze city in the mountain area is very limited, the requirement of road or garage crossing below the Yangtze city is met, the fluctuation range of the water level (in the reservoir area) is large, and the requirement of ecological landscape is high, so that the applicant proposes a river step type bank protection which can adapt to the characteristic water level change, can meet the flood control, ecological landscape and three-dimensional traffic requirements of the mountain area, has large water level fluctuation range and the like and is suitable for reservoir regulation and storage.
