A combined energy-dissipating embankment of vegetation and artificial embankment and its construction method

Abstract

The invention discloses a vegetation and artificial levee combined type energy dissipation dike which comprises a sloping dike and wave absorbing vegetation, wherein the top of the sloping dike is covered with the wave absorbing vegetation; the sloping dike comprises a riprap foundation bed, a riprap dike core, a trepanning caisson, a dry stone protective face and an artificial wetland material; the riprap dike core is thrown to and fills the top of the riprap foundation bed; the trepanning caisson is embedded in the riprap dike core; the dry stone protective face covers the slope of the riprap dike core; the artificial wetland material is filled in the trepanning caisson and the dike top of the riprap dike core; and the surface of each of the dry stone protective face and the artificial wetland material is covered with the wave absorbing vegetation. The vegetation and artificial levee combined type energy dissipation dike organically combines structural wave absorption and vegetationwave absorption to ensure and keep the beautiful natural landscape of a coastal wetland and obtain a better wave absorption effect with a smaller floor space and engineering quantity. The invention further provides a construction method of the vegetation and artificial levee combined type energy dissipation dike.

Description

technical field [0001] The invention relates to the technical field of coastal wetland protection and wave dissipation, and more specifically relates to an energy-dissipating embankment combined with vegetation and an artificial embankment and a construction method thereof. Background technique [0002] Coastal wetlands refer to the transition zone between terrestrial ecosystems and marine ecosystems. According to the definition of the International Convention on Wetlands, the lower limit of coastal wetlands is 6 meters below sea level, and the upper limit is the freshwater or brackish water lakes and swamps connected to inland river basins above the spring tide line, as well as the river sections of rivers that cannot be reached by seawater upstream. Coastal wetlands are precious natural resources and one of the important ecosystem components with irreplaceable comprehensive functions. [0003] In order to protect coastal wetlands from the damage of open sea waves, the cur...

AI Technical Summary

Problems solved by technology

[0003] In order to protect coastal wetlands from the damage of open sea waves, the current traditional breakwaters for coastal wetlands, on the one hand, require a large area of ​​land and a large amount of engineering to obtain ideal wave dissipation effects; on the other hand, they are made of concrete and The wave-absorbing structure made of stones is incompatible with the lush wetland landscape, destroying the ornamental value of the wetland landscape
