Plate-and-frame type river sediment ecological protection slope for sponge city construction and preparation method thereof

Abstract

The invention discloses a plate-and-frame type river sediment ecological protection slope for sponge city construction and a preparation method thereof. The protection slope comprises an obliquely-arranged slope body, and a plurality of ecological basins which are arranged on the surface of the slope body and form a step shape, wherein the interior of each ecological basin is provided with an ecological module unit; and each ecological module unit is successively provided with a gravel layer, a silt layer and an aquatic plant layer from bottom to top. The preparation method for the protectionslope provided by the invention comprises the following steps: building the slope body, allowing the plurality of the ecological basins to be arranged on the slope body, and respectively filling eachecological basin with the gravel layer, the silt layer and the aquatic plant layer. The protection slope provided by the invention has the following significant advantages: the protection slope adoptsan integral ecological protection slope system, can effectively protect the stable ecological structure of a side slope, fully utilizes the value of river sediment during preparation to form the ecological basins with an ecological mode of sediment improved soil, porous water-permeable bricks and amphibious plants, has the characteristics of convenient construction, ecology, beautiful appearance,high silt utilization rate, etc., is easy to maintain and has low cost.

Description

technical field [0001] The invention belongs to the field of river channel ecological restoration, and in particular relates to a plate-and-frame type river channel bottom mud ecological slope protection for sponge city construction and a preparation method thereof. Background technique [0002] The middle and lower reaches of the Yangtze River in China have always been rain-prone areas, resulting in densely distributed various branch water systems in the south of the Yangtze River, and because the southern part of Jiangsu is mostly plains, most of the rainwater is often discharged into the surrounding water bodies through the urban rainwater pipe network, resulting in the rainy season. The average water surface height of the river has risen sharply. In addition, the long-term accumulation of silt in the river often creates great resistance to the smooth flow of the water body, resulting in the inability of the river to flow normally. Therefore, dredging in Hanoi is usually...

Problems solved by technology

[0003] At present, the ecological slope protection technology in my country is constantly improving, but most of them focus on the structural aspects. For example, the utility model with the patent number 201621213261.2 discloses a kind of ecological slope protection for water conservancy projects. The slope protection process is cumbersome and expensive, and there is no river Dredging has not fundamentally solved the erosion of the river by the rising water level, let alone realized the resource advantage of the river sediment

The utility model with the patent No. 201621117910.9 discloses a new type of ecological slope protection. The focus of this slope protection is to improve the ecological slope protection base. Maximize the role of plants in slope protection
