Mixed dike body permeable type ecological beach-making project

Abstract

The invention discloses a mixed dike body permeable type ecological beach-making project. The project is arranged on upstream of the diara and the branching branches, and comprises a spur longitudinaldike arranged downstream and a spur dike arranged on the upstream of the spur longitudinal dike, the length of the spur dike is less than the length of a vertical embankment section of the spur longitudinal, flow passage holes are formed in the spur longitudinal dike and the spur dike, a back-silting area II is arranged between the spur longitudinal dike and the spur dike, and a back-silting areaI is arranged behind the dike body of the spur longitudinal dike. According to the mixed dike body permeable type ecological beach-making project, a combined type permeable dike group structure is adopted, thus flow passage can be achieved, the flow velocity can be slowed down, the siltation of sediment around a beach body is facilitated, and good beach-making effect is achieved; the combined type permeable dike group structure is adopted, thus the flow velocity field around the side beach becomes rich and diverse, and the suitable space is provided for aquatic plants, small aquatic animals and microorganism around the beach body to survive, inhabit, spawn and bait. In the process of beach making, the aquatic ecological environment around the beach body can be further enriched.

Description

technical field [0001] The invention relates to a beach-building project, in particular to a hybrid dam body permeable ecological beach-making project. Background technique [0002] According to the relationship between the beach body and the river bank, the beach body can be classified into three types: edge beach, central beach and low beach at the head of the island. The edge beach is a beach body attached to one bank, which is basically in the same direction or has a small intersection angle with the current. The basic characteristics of the edge beach are: the beach body is usually located in the slow flow area, distributed in the straight and widened channel. Some of the shoals are closely connected with the river bank, and some are semi-separated (leaving string ditches). The midshore is a relatively independent underwater sedimentation body. The basic characteristics of mid-shoals are: they are generally located in widened river channels, some are relatively stabl...

Problems solved by technology

In recent years, although some researches have been done on ecological silt-promoting beach building, the technologies that can be popularized and applied are still very limited. As the country has more and more ecological and environmental protection needs for inland rivers, it is urgent to develop new types of water that can be quickly and effectively applied to inland rivers.
