Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. In the present specification, the terms "upper", "inner", "middle", "left", "right" and "one" are used for convenience of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the corresponding parts may be changed or adjusted without substantial technical changes.

As shown in fig. 1, the embodiment discloses a vertical ecological bank protection, including multistage cascaded guest check gabion mesh retaining wall 10, multistage spud pile 20 that set up in succession from the bottom up in the bank direction of height to and with the corresponding a plurality of fixed plates 30 of multistage guest check gabion mesh retaining wall 10, next stage at least part of the upper surface of guest check gabion mesh retaining wall 10 contacts with its adjacent last stage the lower surface of guest check gabion mesh retaining wall 10. Multistage the upper surface of Bingge gabion net barricade 10 has laid multistage planting matrix respectively and has packed 40, and is a plurality of fixed plate 30 is fixed in multistage respectively plant matrix packs 40's front surface, it is located to plant matrix packs 40 fixed plate 30 with between the Bingge gabion net barricade 10, multistage the upper portion of spud pile 20 is respectively with a plurality of fixed plate 30 is fixed mutually, multistage the lower part of spud pile 20 respectively with multistage Bingge gabion net barricade 10 is fixed mutually. The bottom of the spud 20 located at the lowest stage may also be fixed in the soil. Preferably, the height of the fixing pile 20 is 200mm higher than that of the binge gabion retaining wall 10, and the height of the fixing plate 30 is 200 mm.

The Bingge gabion net retaining wall 10 comprises a gabion net cage, wherein gravel packing is arranged in the gabion net cage. The sandstone packing has a filtering effect, and sludge in water flow is precipitated in stone gaps of the sandstone packing, so that the growth of plants can be promoted, and the ecological balance is restored while the bank is protected. The sand and stone filler has more gaps, is beneficial to water body exchange and the increase of the biological total amount of fish, amphibians, aquatic plants and microorganisms.

The planting matrix filler 40 includes coarse sand and sandy soil, and the coarse sand is laid on the upper surface of the sandy soil. Preferably, the coarse sand is coarse sand with the thickness of 50 mm to 2mm, and the sandy soil is sandy soil with the thickness of 150 mm to 30 mm.
