(4) Beautifying the environment: Through the construction of ecological ponds and reservoirs, the aquatic environment is beautified, the surrounding ecological landscape is enhanced, and people's leisure and recreational space is increased.
[0003] In the construction of ecological ponds and reservoirs, retaining walls are needed at the edges of the ponds or pools to serve as water barriers, supports, and protect the water. These retaining walls keep the water within the pond, allowing for the growth of plants and animals, facilitating the construction of the ecological pond / reservoir, supporting structures such as sluice gates, and preventing water from flowing out. They also protect the foundation, surrounding soil, and surface materials from erosion and washout. The perimeter of a pond / reservoir typically includes both excavation and fill areas, and the retaining wall design must be adapted to these areas. Therefore, retaining wall structures are essential for the construction of ecological ponds and reservoirs. Utility Model Content
[0004] This utility model provides a retaining wall structure for ecological wetlands to play a role in water blocking, support and protection in the construction of ecological ponds and reservoirs.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An ecological wetland retaining wall structure is provided, including a landscape pond. Its innovation lies in that it also includes an earthen wall surrounding the landscape pond, comprising a retaining wall for excavation areas and a retaining wall for filling areas.

[0009] Furthermore, the slope ratio of the retaining wall section near the landscape pool in the excavation area is 1:0.25; the slope ratio of the retaining wall section near the landscape pool in the fill area is 1:0.2.
[0010] Furthermore, the reinforced sections of both the excavation retaining wall and the filling retaining wall are triangular in shape.
[0011] Furthermore, the reinforced part of the retaining wall in the excavation area and the edge where they meet are set as a filter layer. The filter layer is stepped, and the other two sides are inclined upwards. The bottom corner of the reinforced part of the retaining wall in the excavation area is formed by rammed clay, and the uppermost edge is also formed by rammed clay, with a slope ratio of 1:2. The rest of the reinforced part is filled with permeable filler.
[0012] Furthermore, the reinforcing section and the edge of the retaining wall in the embankment area that meet the reinforcing section slope upwards in the direction away from the reinforcing section, with a slope ratio of 1:0.15; the bottom edge is set horizontally; the other edge is set downwards with a slope ratio of 1:2; the reinforcing section of the retaining wall in the embankment area is formed by filling with soil.

[0020] The technical solution of this utility model will be clearly and completely described below through specific embodiments.
[0021] This utility model discloses a retaining wall structure for an ecological wetland, including a landscape pond 1 and an earthen wall surrounding the landscape pond. To accommodate excavation and fill areas around the pond, the earthen wall includes a retaining wall for the excavation area and a retaining wall for the fill area, as described below. Figure 1 and Figure 2 As shown. Both the retaining wall in the excavation area and the retaining wall in the fill area include a retaining wall section 2 and a reinforcing section 3. The retaining wall section 2 is located between the reinforcing section 3 and the landscape pool 1, and the side of the retaining wall section 2 closest to the landscape pool 1 is inclined away from the landscape pool. Preferably, the slope ratio of the side of the retaining wall section 2 closest to the landscape pool in the excavation area is 1:0.25; the slope ratio of the side of the retaining wall section 2 closest to the landscape pool in the fill area is 1:0.2.
[0022] The bottom of the retaining wall section 2 is lower than the bottom of the landscape pool 1, and the part near the landscape pool extends below the landscape pool. This arrangement allows the bottom of the retaining wall section to be away from the liquid surface of the landscape pool, thus making it more stable. The bottom of the retaining wall section 2 of both the excavation area retaining wall and the fill area retaining wall is inclined upward towards the landscape pool 1, and the slope ratio is 0.2:1.
[0023] The retaining wall 2 of this invention is formed by masonry. In this embodiment, the strength of the masonry material is MU30, and the strength of the mortar is Mb10.
[0024] The landscape pool is provided with a polyester filament composite geomembrane 4, a rammed clay layer 5 and a rubble layer 6 arranged from bottom to top. Preferably, the thickness of the rammed clay layer 5 and the rubble layer 6 is 0.3m.
[0025] The reinforcing part 3 of both the retaining wall in the excavation area and the retaining wall in the filling area of this utility model is triangular in shape.
[0026] The edge where the reinforcing section 3 of the retaining wall in the excavation area contacts the retaining wall section 2 is designated as a filter layer 7. The filter layer 7 is stepped, preferably 0.3m thick, and formed of crushed stone. The other two sides of the reinforcing section 3 of the retaining wall in the excavation area are inclined upwards. The bottom corner of the reinforcing section of the retaining wall in the excavation area is formed by rammed clay 10, which increases the overall stability of the retaining wall. The uppermost edge is also formed by rammed clay 10 with a slope ratio of 1:2. The upper rammed clay can seal off surface water, preventing excessive surface water from seeping into the retaining wall and affecting its durability. The remaining part of the reinforcing section 3 is filled with permeable filler to facilitate drainage of the retaining wall structure.
[0027] In the fill section, the edge where the reinforcing part 3 and the retaining wall part 2 meet slopes upward away from the reinforcing part, with a slope ratio of 1:0.15; the lowest edge is horizontal; the other edge (the third edge) slopes downward, with a slope ratio of 1:2; the reinforcing part 3 of the fill section retaining wall is formed by filling with soil. Since the fill section is lower than the design plane, there are fewer drainage issues compared to the cut section, so no filter layer is provided.
[0028] Green plants 8 are planted in the landscape pool 1 and on the upper surface of the reinforced sections of the retaining walls in the excavation and filling areas to enhance the aesthetics and carry out ecological restoration.
[0029] Safety railings 9 must be installed at the top of the retaining wall section 2 in both the excavation and filling areas to prevent tourists or other personnel from accidentally falling into the water and to increase safety.
[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model. The technical content for which protection is sought in the present utility model has been fully recorded in the technical requirements.
