Description

Technical Field

[0001] The present invention relates to the technical field of ecological revetments, and in particular to an assembled ecological revetment. Background Art

[0002] In recent years, the remarkable advantages of assembled structures are reflected in the industrialized and mechanized production and construction processes. In view of the problems of many construction procedures and low industrialization degree in existing waterway engineering, there appears a "one-key" ecological revetment, which adopts a structure of a large integral empty box nested with fish nests and uses mortise and tenon structures to connect with each other. The structure is simple and convenient to install. Further, the precast box-type assembled revetment stacks the box precast components on top of each other and can be used for structures with a retaining height greater than 4 meters.

[0003] At the same time, people are also exploring the diversification of revetment functions. One of the main ideas is to realize ecological functions by cultivating plants planted on the revetment. For example, the embedded ecological revetment uses permeable and breathable materials to design a stepped ecological brick framework with five layers, and embeds the entire framework into the soil to form an embedded and hidden brick revetment, which is beneficial to the growth of plants; the snap-type ecological revetment based on groundwater filtration and collection technology is used to purify, filter, infiltrate, and collect rainwater while ecologically strengthening the dike; the assembled ecological revetment realizes the functions of rainwater collection and automatic watering by burying rainwater storage boxes below the planting area.

[0004] In addition, there are also structures such as concrete pile ecological revetments and concrete grid girder stacked beam assembly structure ecological revetments for assembled revetments, which all provide good solutions to the ecological problems of traditional hardened river revetments. However, the above revetment structures are either too simple in structure and single in function, or complex in structure and high in cost. Summary of the Invention
