The proportion of cement mortar can be selected to be 1: 2.5.
Furthermore, a layer of non-woven fabric is arranged between the stone wall and the rammed earth layer, so that the original foundation soil layer can be stabilized.
Further, the stone wall body comprises a set of dimension scope for 20~40 cm's stone, and the gap between the stone is filled with sand and soil. The stone wall of this kind of structure has the water purification function, and the rainwater on the bank passes through behind the stone wall, and impurity wherein flows into in the landscape water body after being filtered and purified by the wall body. The gaps between the stones of the stone wall body are filled with sand, plants can grow on the gaps, the ecological environment is optimized, and the shoreline is beautified.
Further, the rammed earth layer extends to the direction of the lake bottom for a distance of at least 1 m.
The invention is made of reinforced concrete, and the size of each component and the internal reinforcing steel bars are determined by structural calculation according to the height of the revetment and the condition of the foundation.
Has the advantages that: (1) the invention forms the respirable ecological revetment by designing the ecological baffle plate, does not destroy the biological communication between the water body and the shore; (2) the revetment is made of reinforced concrete, so that the revetment has good durability and can be kept stable for a long time; (3) the invention can filter rainwater impurities flowing into the landscape water body from the bank, plays a role in purifying water and realizes win-win effect of landscape effect and ecological effect.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Examples
The step-type ecological revetment comprises a square foundation 1 buried in the lake bottom, wherein the square foundation is buried in the lake bottom to a depth of more than 80cm and generally reaches a firm and stable foundation to ensure the structural safety. The upper part of the square foundation 1 is sequentially provided with a first revetment structure body and a second revetment structure body which have the same structure, the first revetment structure body is composed of a group of ecological frames, each ecological frame comprises a water-retaining cuboid frame which is built by columns 2, cross beams 3 and longitudinal beams 4, the water-facing surface of each water-retaining cuboid frame is provided with an ecological baffle 5, and the ecological baffle 5 is provided with a group of ecological vertical holes 6 which are convenient for ecological communication; the design of ecological vertical holes increases the harmony of the landscape, and simultaneously, a channel between water and the bank is formed, so that the biological communication effect is achieved, and the ecological balance of the water bank is maintained. Stone wall bodies 7 are paved on the back water surface of the ecological baffle 5, ramming soil layers 8 are paved below and behind the stone wall bodies 7, the ramming soil layers 8 extend to natural soil 9, and lawns 10 are paved on the surface of the natural soil 9 to protect the soil from being washed away by rainwater.
