Embodiment 1

[0026] Example 1 Ecological Reconstruction Technology and Method of Hardened Revetment in Suburbs

[0027] Such as figure 1 The suburban hardened revetment shown after ecological transformation includes the dehardened revetment 1, the ecological soil 2 laid on the dehardened revetment, and several concrete retaining grooves 3 embedded in the hardened revetment 1 , different plants are arranged on the dehardened revetment 1 .

[0028] Wherein, the dehardened revetment 1 removes the hardened structure to expose the soil below the revetment, and the slope of the revetment is reduced to 20%. The ecological soil 2 has a thickness of 5cm.

[0029] The shape of the concrete retaining tank 3 shown in this embodiment is a rectangle with an open top, and the length, width and height of the concrete retaining tank are 200cm×20cm×10cm, half of which is embedded in ecological soil. The concrete retaining grooves are arranged in regular rows, wherein any two adjacent rows of ecologic...

Embodiment 2

[0032] Such as figure 1 The suburban hardened revetment shown after ecological transformation includes the dehardened revetment 1, the ecological soil 2 laid on the dehardened revetment, and several concrete retaining grooves 3 embedded in the hardened revetment 1 , different plants are arranged on the dehardened revetment 1 .

[0033] Wherein, the dehardened revetment 1 removes the hardened structure to expose the soil below the revetment. Considering flood safety, the revetment slope is reduced to 25%. The ecological soil 2 has a thickness of 5cm.

[0034] The shape of the concrete retaining tank 3 shown in this embodiment is a rectangle with an upper opening, and the length, width and height of the concrete retaining tank are 100cm×20cm×10cm, half of which is embedded in ecological soil. The concrete retaining grooves are arranged in regular rows, wherein any two adjacent rows of ecological brick boxes are arranged in a staggered manner.

Embodiment 3

[0037] Such as figure 1 The suburban hardened revetment shown after ecological transformation includes the dehardened revetment 1, the ecological soil 2 laid on the dehardened revetment, and several concrete retaining grooves 3 embedded in the hardened revetment 1 , different plants are arranged on the dehardened revetment 1 .

[0038] Wherein, the dehardened revetment 1 removes the hardened structure to expose the soil below the revetment. Considering flood safety, the revetment slope is reduced to 30%. The ecological soil 2 has a thickness of 5cm.

[0039] The shape of the concrete retaining tank 3 shown in this embodiment is a rectangle with an open top, and the length, width and height of the concrete retaining tank are 150cm×15cm×10cm, half of which is embedded in ecological soil. The concrete retaining grooves are arranged in regular rows, wherein any two adjacent rows of ecological brick boxes are arranged in a staggered manner.

Abstract

The invention relates to a method for ecological renovation of suburban hardened revetments. The method includes: removing a hardened structure of a suburban revetment and eliminating the gradient to facilitate rooting and growing of plants and water and soil conservation; laying ecological soil and fixing the soil by a preserving trough to prevent collapse and water and soil loss of the revetment; and arranging reasonable plants to beautify the revetment and purify water. The suburban hardened revetment is ecologically renovated by taking measures like de-hardening, gradient elimination, ecological soil laying and fixing, beautifying and purifying plant arranging and the like to the revetment. On the basis of combining existing ecological restoration and reconstruction of the hardened revetment, aiming at characteristics of the suburban hardened revetment, water and soil linking is realized by removing the hardened structure, and gradient elimination of the revetment provides a condition for plant rooting and is beneficial to prevention of water and soil loss. Reasonable greening, beautifying and water-purifying plants are arranged, so that ecological renovation of the hardened revetment is realized.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and relates to an ecological reconstruction technical method for hardened revetments in the suburbs. Background technique [0002] As an important part of the river, the river bank is the link between the water ecosystem and the terrestrial ecosystem, the link between the river's water-land ecotone and the riparian zone, the active functional area of ​​the geochemical element cycle, and the dynamic exchange process between surface water and groundwater. Carrier. Changes in riparian ecosystems play the role of corridors, filters, and natural barriers for material, energy, and biological flows between land and water ecosystems. [0003] Since the founding of the People's Republic of my country, many reservoirs, dams, and dikes have been built on large, medium, and small rivers, and a series of engineering measures such as lining, revetment, dangerous work reinforcement, river bed dr...
