Embodiment 1

[0019] attached figure 1 , attached figure 2 It shows that in the hard bank slope channel, a row of wooden piles 4 is drilled along the 1 foot line of the hard river bank slope. Cloth 6, lay block stone 5 at the angle between stake 4 towards the water side and the river bed, tie the twigs of willow into live branch bundle 2, fill gravel, pebble, ceramsite and zeolite 3 in live branch bundle 2, Put the live branch bundle 2 between the wooden pile 4 and the hard river bank slope 1 in parallel with the river bank, and cover the live branch bundle 2 with the covering soil 7; the wooden pile 4 is 0.5m away from the vertical revetment.

[0020] After implementing the inventive method, live branch bundle 2 will grow out live branch root system 8 and live branch tender shoot 9 rapidly, and the reinforcement effect of live branch root system 8 has further guaranteed the stability of bank slope, and live branch tender shoot 9 grows up one year and promptly It can form lush bank slope...

Embodiment 2

[0022] attached figure 1 , attached figure 2 It shows that in the hard bank slope channel, a row of concrete imitation wood piles 4 is drilled along the 1 foot line of the hard river bank slope, and the top of the concrete imitation wood piles 4 is slightly higher than the top of the hard river bank slope 1. 4 Lay geotextile 6 on the backwater side, lay stones 5 at the angle between the concrete imitation wooden stake 4 facing the water side and the river bed, tie the twigs of willow and alder into live branch bundles 2, in the live branch bundle 2 Fill with gravel, pebbles, ceramsite and zeolite 3, put the bundle of live branches 2 between the concrete imitation stake 4 and the hard river bank slope 1 in a manner parallel to the river bank, and cover the bundle of live branches 2 with the covering soil 7; The concrete imitation wood pile 4 is 0.75m away from the vertical revetment.

Embodiment 3

[0025] attached figure 1 , attached figure 2 It shows that in the hard bank slope channel, a row of wooden piles 4 is drilled along the 1 foot line of the hard river bank slope. Cloth 6, lay stones 5 at the angle between the side of the stake 4 facing the water and the river bed, tie the twigs of willow, alder and black poplar into a live branch bundle 2, fill gravel and pebbles in the live branch bundle 2 , ceramsite and zeolite 3, the live branch bundle 2 is placed between the wooden pile 4 and the hard river bank slope 1 in a manner parallel to the river bank, and the live branch bundle 2 is completely covered with the covering soil 7; the wooden pile 4 is separated from the vertical revetment 1.0m.

[0026] After implementing the inventive method, live branch bundle 2 will grow out live branch root system 8 and live branch tender shoot 9 rapidly, and the reinforcement effect of live branch root system 8 has further guaranteed the stability of bank slope, and live branch...

Abstract

The invention relates to a method for forming an ecological embankment of vertical revetment live branch bundles. The method is characterized in that a row of wood piles or concrete imitative wood piles is driven along the bankside toe line of a riverway, twigs of willows, alders or black poplars are bunched into live branch bundles, gravels, pebbles, haydites and zeolites are filled in the live branch bundles, and the live branch bundles are arranged between the wood piles or the concrete imitative wood piles and the bankside of the riverway parallel to the riverbank. Therefore, the problems of renovating vertical revetment waterfront plants along the riverway and constructing an ecological embankment are solved. The live branches used by the embankment have good tolerance to water logging, thereby quickly budding and forming a vegetation system, creating good living environment for riverbank living things, and beautifying riverbank landscape, and on the other side, plants, purifying filter materials and surface-attached microorganisms have better purifying effects on pollutant and improve the water quality of the riverway. The embankment is very convenient to construct, maintain and manage, and has better transformation and application prospects of the ecological renovation of the vertical revetment.

Description

technical field [0001] The invention relates to an ecological river bank revetment construction technology, in particular to a method for forming an ecological bank revetment with live branch bundles for vertical revetments. Background technique [0002] Vertical revetment is a common form of river bank slope, especially in urban rivers. Before the present invention, the bank revetment technology of existing river vertical revetment is mainly hard type bank revetment technology. [0003] The hard revetment mainly uses mortar or dry block stones, cast-in-place concrete, prefabricated concrete blocks, etc. to protect the river bank slope. These structures have good effects on maintaining bank slope stability, preventing soil erosion and ensuring flood control safety, but they also have adverse effects on the bank slope's ecology, environment and landscape to varying degrees: their hard materials and closed structures damage the river channel The water-land ecotone zone cause...
