Composite ecological bank protecting structure and construction method thereof

Abstract

The invention relates to a composite ecological bank protecting structure and a construction method thereof. The composite ecological bank protecting structure comprises a low-water-level area bank protecting unit, a normal-water-level area bank protecting unit, a flood-stage area bank protecting unit and a landscape accessory structure arranged on the flood-stage area bank protecting unit in a section mode and used for viewing, the low-water-level area bank protecting unit comprises a rubble slope base and a hollow concrete block, and the normal-water-level area bank protecting unit comprisesa Reynolds protecting cushion layer, an ecological buffering tank, a clean water wetland and a water collecting dark canal; and the bottom of the water collecting dark canal communicates with the bottom of the ecological buffering tank through a communicating pipe, and the flood-stage area bank protecting unit comprises ecological grassland, a drainage ditch and a seepage dam. According to the different characteristics of a river bank in each area, the flood control, ecology and landscape function of the river bank are organically combined, the problems of poor ecological and landscape effectof a traditional bank are solved, and the ecosystem and bank protecting stability of a river bank belt are improved.

Description

technical field [0001] The invention relates to the field of ecological revetment, in particular to a composite ecological revetment structure with integrated functions of flood control, landscape and ecological restoration and its construction method, especially suitable for rivers with large water level changes. Background technique [0002] Ecological bank revetment is an artificial bank revetment that follows the principles of recycling, reuse and sustainable development, and rebuilds or repairs the water and land ecological structure of the original revetment of the river to restore it to a natural river bank or has the "permeability" of the natural river bank through artificial measures. It has the functions of regulating the hydrological state of the river, filtering out pollutants, creating a biological habitat, and maintaining the biodiversity of the water body's coastal zone. [0003] The concept of compound ecological revetment is gradually formed in the process o...
