Description

Technical Field

[0001] The present invention belongs to the technical field of ecological water conservancy engineering, and specifically relates to a prefabricated ecological pile - slab revetment unit and a prefabricated ecological pile - slab revetment. Background Art

[0002] A revetment refers to a reinforcement structure adopted for the bank slopes in areas such as estuaries, rivers, lakes, and coasts to prevent the invasion, scouring by waves and water currents, and the collapse of the bank slopes caused by earth pressure and groundwater seepage pressure. The purpose of the revetment structure is to prevent disasters such as lateral erosion of rivers and bank collapses caused by local scouring of river channels.

[0003] Currently, most revetment structures adopt gravity retaining wall structures and other gravity wall - type structures evolved from them. Although they meet the basic requirements of river revetments in water conservancy projects and have certain improvements in adapting to the ecological environment, they still cannot avoid the following disadvantages:

[0004] First, the investment is relatively high, and it cannot meet the balance of technical economy.

[0005] Second, the ability to adapt to foundation deformation is weak, which will cause local settlement damage, thereby increasing the maintenance cost during later operation.

[0006] Third, the construction difficulty is relatively large, especially in river sections with poor construction conditions. If other temporary projects are used for assistance, the investment cost will be further increased.

[0007] Fourth, it will have an impact on the regional ecological environment and hinder the formation and development of habitats for animals and plants.

[0008] To improve the disadvantages of traditional revetment structures, currently, row - pile structures or sheet - pile structures similar to building foundation pit support are adopted. Although the problem of adapting to foundation deformation is solved and the construction difficulty is reduced, it still cannot meet the requirements of technical - economic balance and ecological environmental protection. Summary of the Invention
