Riverway rigidity revetment ecologicalization method

Abstract

The invention discloses a riverway rigidity revetment ecologicalization method. The problem that the daily drainage effect of riverways is weakened when ecological restoration boxes are mounted on revetments is solved. According to the technical scheme, the method mainly comprises the steps that cleaning is conducted; a plurality of parting stops are laid on a slope bank section through cement and divide the slope bank section into a plurality of unit blocks; porous concrete is prepared, a plurality of porous concrete hanging plates are laid, and vine plants are planted on the porous concrete hanging plates; the porous concrete hanging plates are mounted between the two parting stops, located at the joint with a vertical bank section, of the slope bank section; a climbing net is arranged on the vertical bank section, and ends of the vine plants are bonded to the climbing net through cotton ropes; and the unit blocks are backfilled with nutrient soil, herbaceous plants and suffruticosa plants are planted, and the original riverway drainage effect is maintained while rigidity revetment ecologicalization is achieved.

Description

technical field [0001] The invention relates to bank revetment restoration, in particular to an ecological method for hard bank revetment of a river course. Background technique [0002] For a long time, in order to adapt to human activities, the construction of various basic water conservancy projects has mostly been a simple and crude quick-drainage idea. It only considers how to make the flood flow faster and more smoothly. Therefore, the original ecological river channel was cut and straightened, and the river channel The revetment structure also mainly adopts mortar or dry block stone revetment, cast-in-place concrete revetment, and prefabricated concrete block revetment. Due to their poor water permeability, this type of bank revetment cuts off the material connection between the river and the soil, making the water storage and seepage capacity of the river worse. It makes it difficult for various aquatic plants to grow on hard slopes, and various aquatic animals lose...

Problems solved by technology

[0004] However, when the ecological reset box is installed on the revetment, the distance between the two revetments of the river will be reduced, resulting in the reduction of the cross-section of the river, which will increase the normal water level of the river and weaken the daily drainage effect of the river.
