Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A water quality purification ecological revetment structure of a multistage wetland is formed as shown in figures 1-4 and comprises a revetment waterproof retaining wall 1, a wetland ecological revetment 2 is arranged on the revetment waterproof retaining wall 1, and a green isolation belt 3 is arranged beside the wetland ecological revetment 2; the wetland pool waterproof retaining wall comprises a wetland pool waterproof retaining wall 4, wherein an ecological isolation belt 5 is arranged on the wetland pool waterproof retaining wall 4; the wetland ecological revetment 2 comprises a grouted blockstone layer 6, and the surface of the grouted blockstone layer 6 is in a step shape; green median 3 is equipped with gravel layer 8 including locating gravel layer 7 on revetment waterproof barricade 1 on the gravel layer 7, is equipped with straight water plant layer 9 on gravel layer 8.

The grouted blockstone layer 6 is built by adopting a mortar paving method, when in building, the blocks are laid horizontally in layers, staggered joints are formed up and down, and cement is filled, so that natural and random terraced step transition with high strength and good waterproofness to a wetland is formed, and the terraced step transition can prevent water falling when a walker plays.

The green isolation zone 3 is a transition area between the shoreside and the wetland. The gravel layer 7 and the sand stone layer 8 of the green isolation belt 3 not only can stabilize the emergent aquatic plant layer 9, but also can be used as a microorganism adhesion substrate. The gravel layer 7, the gravel layer 8 and the emergent aquatic plant layer 9 can play a role in purifying water quality, and simultaneously can prevent the silt flushed by rainwater from entering the wetland to be deposited, so that the environment is prevented from being damaged by building a drainage ditch.

And a soil covering layer 10 is arranged on the grouted blockstone layer 6, and a native crop layer 11 is arranged on the soil covering layer 10. The native crop layer 11 is preferably ryegrass, which provides a certain purification function.

Ecological median 5 includes foraminiferous grout rubble layer 12, and foraminiferous grout rubble layer 12 is gone up or the next door is equipped with metalling 7, is equipped with gravel layer 8 on the metalling 7, is equipped with very water plant layer 9 on the gravel layer 8. The ecological isolation belt 5 has the same structure and the same effect as the green isolation belt 3.

And a natural stone block layer 13 or a ridge layer 14 is arranged on the grouted block stone layer 12 with the holes. The natural stone layer 13 or the ridge layer 14 arranged on the grouted stone layer 12 with holes provides multiple choices for the actual construction of the ecological isolation belt 5, so that the multistage wetland revetment structure is richer, the layering is increased, and the construction structure is more natural.

The grouted and blocky stone layer 12 with holes leaves holes during construction, and the holes are used as water outlets of each stage of wetland.

The stones used in the natural stone layer 13 are preferably selected from local materials, which not only serve a decorative function, but also provide a foundation for the growth of plants in later stages of the site.

The ridge layer 14 is a plant layer on the ridge, and the structure of the ridge layer can be that ryegrass and native species are planted on the gravels and the soil.

The thickness of the gravel layer 7 is 200mm-300mm, and the particle size of the gravel layer 7 is 30mm-50 mm. The crushed stone of the crushed stone layer 7 has a particle size of 30mm to 50mm, and the rough surface of the crushed stone layer contributes to the retention of microorganisms. The thickness of the crushed stone layer 7 is 200mm-300mm, so that a good stabilizing effect and a good purifying effect can be achieved.

The thickness of the sand layer 8 is 250mm-350 mm. The sand layer 8 is convenient for planting the upper water plant layer 9. The sand layer 8 can have better stabilizing effect and purifying effect when the thickness is 250mm-350 mm.

The utility model discloses the preferred multistage wetland of being applied to, the structure directly build between multistage wetland revetment and each wetland pond can.
