Problems solved by technology
In the process of water level change and rainfall erosion, because the slope protection structure fails to effectively intercept or impede the movement of soil particles on the surface and inside of the slope, some water and soil loss will still occur. After permanent water level fluctuations and rainfall scouring, the slope may be gradually eroded and even cause a large amount of soil particle loss, which cannot effectively maintain water and soil for a long time, and will also reduce the effect of vegetation restoration. Therefore, how to essentially avoid water and soil loss is still a current issue The most critical problem of controlling the water-fluctuation zone

Embodiment 1
[0096] Referring to the above-mentioned construction method, this embodiment is used for the slope test section of the Kuwan subgrade section YK22+730-YK22+970 of Qianhuang Expressway YK22+730-YK22+970 in Chun'an County, Hangzhou City, Zhejiang Province. The length of the test section is 100m. The embankment fills the side slope, the north side is close to the expressway road, the south side is adjacent to the lake, the east side intersects with another side slope, and the west side is the extension of the side slope. The total height of the slope is about 28m, which is divided into three levels of filling. The first level of slope is about 8m high with a slope ratio of 1:2.00; the second level of slope is about 12m high with a slope ratio of 1:1.75; About 8m, the slope ratio is 1:1.50, and there is a 2m wide platform at the junction of every two grades of slopes.
[0097] The area is warm and humid, with abundant rainfall and sunshine. The average annual precipitation is 1100...

Abstract
The invention discloses a hydro-fluctuation belt side slope ecological management method based on an inverted filter. The hydro-fluctuation belt side slope ecological management method can effectively protect slope surface soil particles against loss, can provide a stable growth environment for plants in a hydro-fluctuation belt, ensures soil required by vegetation restoration, maintains ecological balance of a bank slope, and eliminates the hydro-fluctuation belt bank slope generated by periodic water level fluctuation.
Description
technical field [0001] The invention relates to bank slope treatment in a water-fluctuation zone, in particular to an ecological treatment method for solving water and soil loss in a water-fluctuation zone based on vertical drainage of a reverse filter layer. Background technique [0002] The ebb zone is a special area where the bank slope is repeatedly inundated due to seasonal water level fluctuations. The vegetation on the water-fluctuation zone becomes sparse through the alternation of dryness and wetness, and the slopes lacking the soil-fixing effect of plant roots are prone to water and soil erosion, which in turn causes the degradation of ecosystem functions, resulting in many ecological problems such as low biodiversity, environmental and visual pollution, etc. , severe cases may even cause geological disasters. [0003] At present, most of the methods for controlling the water-fluctuation zone start with vegetation restoration. This kind of ecological restoration t...
