A H-shaped dam for ecological restoration and protection and its ecological construction method

Abstract

The invention relates to an I-shaped dam for ecological recovery and protection and an ecological construction method thereof, and belongs to the field of ecological recovery and protection of naturalsurface or artificial water and land interlaced zone water buffer zones. A stone cage is adopted for packing stone or soil, or a basket cage is adopted for packing soil, a geotextile sandbag is adopted for packing sand and stone, or ecological concrete or riprap or precast blocks are adopted for building an I-shaped dam, habitat conditions of water and land interlaced zone water buffer zone recovery is improved, wave and energy dissipation is enhanced, sediment deposition is promoted, animal and plant recovery is induced, the biodiversity is improved, algae are captured, the purification processes such as denitrification and dephosphorization of vegetation type shore zone are reinforced, the I-shaped dam measures promote suspended particulate matter or sediments of water bodies such as lakes to become lateral deposition from vertical deposition, carried pollutants are converted to be released at the waterfront edge zone vegetation region from releasing longitudinally to overlying water, multiple plant-type small lakes are formed in dike field areas between the I-shaped dam, and finally an existing algae type water body is converted to be a plant-type water body.

Description

technical field [0001] The invention relates to the field of ecological restoration and protection of water to the buffer zone in the natural or artificial water-land staggered zone on the surface, especially suitable for the coordinated control of internal and external source pollution of water bodies, and the pollution control of overflowing water bodies, specifically a water-land staggered The I-shaped dam and its ecological construction method that carry water to the buffer zone for ecological restoration and protection, and realize the conversion of algae-type water body to grass-type water body. Background technique [0002] The T-shaped dam is a hydraulic structure invented by the predecessors, which is more commonly used for wave dissipation and protection in the water and land ecotone. However, although the traditional T-shaped dam has a certain scale, it has a single function and is generally used for waterway regulation. Because the traditional T-shaped dam is on...

However, although the traditional T-shaped dam has a certain scale, it has a single function and is generally used for waterway regulation

Because the traditional T-shaped dam is only a dam body protruding outward at a certain angle from the coast, the shape and structure are single, and most of them are built with riprap, piles (steel piles, wooden piles or cement piles) or ordinary concrete (concrete) However, the T-shaped dam did not comprehensively consider accelerating the ecological restoration of the water-land ecotone or the buffer zone of the water-land ecotone, intercepting and controlling algae, creating waterscapes, promoting biodiversity conservation, water purification, and realizing the transformation of algae-type water bodies into grass-type water bodies. Traditional impermeable dams are also not conducive to the conservation of biodiversity in the buffer zone from water in the water-land transition zone, and have weak functions in controlling and degrading algae and promoting the transformation of algae-type water bodies into grass-type water bodies
