Problems solved by technology

At present, some ecological berm technologies have been designed, but the technical solutions used are not comprehensive enough, or have some defects
For example, the Chinese invention patent "A New Type of Plant Configuration and Ecological Engineering Technology for River Embankment and Reservoir Release and Revetment" (Patent No.: ZL03146885.3) discloses a plant with vetiver as the main body and other plant species. Ecological engineering technology, but the formation of a complete plant belt not only requires long-term manual maintenance, but also requires a large amount of plant fertilizers, which is not good for the environment; on the other hand, simple plant slope protection lacks certain rigidity during sudden floods or heavy rains cater for extreme situations
The article "Design and Application of Chaohu Ecological Concrete Embankment Demonstration Project" discloses a kind of permeable vegetation ecological concrete, but it adopts the method of pouring a square concrete frame and then pouring ecological concrete in the frame. On the one hand, it cannot Resist the long-term erosion of water flow and rain, on the other hand, it does not consider the habitat of aquatic animals

Embodiment 1

[0039] The hydrological information of the urban river in an experimental site is: the flow is about 800m 3 / d, the annual average precipitation is 1834.7mm, the annual average water level is 8.27m, the lowest water level in the past 10 years is 6.86m, and the highest water level is 9.74m, which requires ecological landscape. Build embankment according to the present invention, the configuration of stake is: every row 5m, a row of 3, the vertical distance of every row is 2m, arranges 3 rows, is bound with root submerged water plant hydrilla on the non-woven mesh belt, planting The seeds of lotus and water onion are filled in the soil bag, and gardenia and canna are planted on the high water line.

[0040]After 3 months of professional maintenance, the plant growth of the berm has reached the design requirements. No obvious erosion was found in the area of ​​the slope depletion zone. The average removal rates of CODMn, NH3-N, and TN in the river water quality were 18%, 70%, an...

Embodiment 2

[0042] The hydrological information of a tributary in a river basin is: 6000m 3 / d, the highest daily precipitation for many years is 180mm, the annual average water level is 16.47m, the lowest water level in recent years is 12.50m, and the highest water level is 21.65m, which requires flood control. Build embankment according to the present invention, the configuration of stake is: every row 8m, a row of 5, the vertical distance of every row is 4m, arranges 4 rows, and the bottom of the non-woven mesh belt is tied with root submerged plant Hytrigala, Rootless hornwort algae and micro-toothed eye vegetables are bundled in the upper part, and the seeds of reed, cattail grass and wild rice stem are planted in the planting soil bags, and coral trees, red leaf trees and vetiver are planted on the high water line.

[0043] Observation after 6 months of professional maintenance shows that there is slight erosion in the area of ​​the ups and downs on the slope, and the berm can well ...

Abstract

The invention belongs to the filed of application of reinforcing dams of riverways, lakes and reservoirs, and discloses an environmental-friendly ecological reinforcing dam system which comprises plant mesh bags arranged in the low water area of a riverway, planting soil bags laid on a slop falling-and-rising area, and ecological concrete blocks. According to the invention, the basic functions of stabilizing the riverways and preventing water and soil loss are realized, and an excellent aquatic ecosystem is also formed, so that the ecological diversity and the purification performance of water quality are facilitated.

Description

technical field [0001] The invention belongs to the field of embankment application of rivers, lakes, reservoirs, etc., and provides an environmentally friendly ecological embankment system, Background technique [0002] Rigid settings such as direct pouring of concrete or anchor piles are often used in traditional river and lake embankments. On the one hand, this impermeable hard material will block the exchange of materials and information between various elements in the water environment, resulting in a decrease in biodiversity and purification capabilities; It is easy to be hollowed out under washing, and the poured berm cannot change accordingly, which eventually leads to the collapse and dislocation of the concrete berm. Especially in the area of ​​the slope of the river channel, its main characteristics are frequent fluctuations in water level, soil flooding and drought, and relatively simple vegetation composition. [0003] In order to overcome the defects of ordin...
