Ecological softening structure of rigid revetment

Abstract

The invention provides an ecological softening structure of a rigid revetment. The ecological softening structure comprises a supporting frame arranged along a revetment base body. A mesh type grid is arranged in the supporting frame, a plurality of cells are formed, and an intercepting layer is arranged outside the supporting frame. Each cell is filled with planting matrixes. Terrestrial plants are planted in the zone above a water level. Emergent aquatic plants are planted in the underwater zone with the water depth smaller than 30 cm. Submerged plants are planted in the underwater zone with the water depth between 30 cm-100 cm. The ecological softening structure is not limited by riverway water depth and is not affected by levee crown back way arranging, the application range is wide, by reasonable matching of the terrestrial plants and the emergent aquatic plants, a beautiful revetment landscape is established, and meanwhile the purifying functions of the emergent aquatic plants and the submerged plants are used for purifying riverway water quality. The ecological softening structure has the advantages of being simple in structure, low in building cost, convenient to construct, easy to maintain and manage and the like, and great economy, practicability and wide applicability are achieved.

Description

technical field [0001] The invention relates to an ecological structure applied in water conservancy projects, in particular to an ecological softening structure of a rigid revetment. Background technique [0002] The traditional river management in our country has been working hard with the goal of "removing water damage and promoting water conservancy". In order to meet people's various needs for flood control, drainage, water supply, irrigation, entertainment, shipping, etc., most of the rivers have adopted safe hard revetment form. With the development of society, everyone realizes that rigid bank revetment has certain negative effects, seriously blocking the connection between water ecosystem and terrestrial ecosystem, changing the ecological function and structure of natural river banks, destroying the ecological process of the river, thereby reducing the self-purification ability, water pollution can not be improved. Human activities have resulted in discontinuous r...

Problems solved by technology

[0003] At present, there are mainly two types of softening technologies for rigid bank revetment. One is to plant weeping vines from the top of the embankment behind the retaining wall and hang them to cover the hard retaining wall. If it is close to the retaining wall, this technology cannot be implemented; the other type is to plant a small amount of emergent plants beside the retaining wall, and use the branches and leaves of the plants to block the hard retaining wall, but it cannot be implemented in deep waterways

At the same time, when the water depth of the river is relatively deep, due to the limitation of plant photosynthesis, it is difficult to restore submerged plants in the river, so the water purification ability is poor

The above two types of technologies are relatively single, affected by multiple factors such as land and water, it is impossible to build a full range of transition zones for terrestrial, emergent and submerged plants, and the landscape effect and purification effect are not very ideal
