Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] This application provides an ecological retaining wall that solves the problem that the precast concrete drainage holes of the ecological retaining wall for planting vegetation are directly exposed, and irrigation water is prone to convergence and splashing when discharged through the drainage holes, impacting the road surface below.

[0046] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0047] Example:

[0048] like Figures 1-3 As shown, this utility model provides an ecological retaining wall, which includes: a base 1, a wall body 10, and several sets of ecological components;

[0049] The wall 10 is vertically mounted on the base 1;

[0050] The ecological components are installed on the wall 10;

[0051] The ecological components include: a precast concrete structure 3;

[0052] The precast concrete structure 3 includes: a planting trough 30 and an extension hopper 31;

[0053] The opening of the planting trough 30 faces upward, and a plurality of water outlet holes 304 are provided at the bottom of the trough;

[0054] The extended bucket 31 is located below the planting trough 30 and is integrally formed with the planting trough 30;

[0055] The bucket wall of the extended bucket 31 gradually approaches the wall 10 from top to bottom, and a water outlet gap is formed between the bottom end of the bucket wall and the wall 10.

[0056] The planting trough 30 is used for planting vegetation, and the extension hopper 31 is used to guide irrigation water flowing from the water outlet 304 to the wall 10.

[0057] like Figure 3 As shown, the interior of the planting trough 30 is provided with a water storage layer 301, a ceramic granule layer 302 and a planting layer 303 from bottom to top;

[0058] The planting layer 303 is planted with vegetation. The planting layer 303 is used for vegetation growth and promotes rainwater infiltration. The planting soil of the planting layer 303 is lightweight planting soil. Lightweight materials are used to replace part of the traditional soil, reducing the overall weight of the planting trough 30. It is suitable for elevated structures and improves the permeability of the soil. The planting layer 303 is planted with water- and drought-resistant plants to beautify the environment, slow down the rainwater flow rate, and absorb water and pollutants through the plant roots.

[0059] The expanded clay layer 302 is laid with expanded clay, which has good water permeability, strong adsorption performance, light weight, and is easy to construct.

[0060] The water storage layer 301 is laid with granular material made of recycled glass, which is environmentally friendly, lightweight and highly durable. The inner wall of the water storage chamber of the water storage layer 301 is coated with a waterproof coating, which can protect the reinforced concrete retaining wall.

[0061] like Figures 1-3 As shown, the wall 10 has a horizontally extending second T-shaped slot 12 on its front side, and the planting trough 30 is provided with a second insert 305 that matches the second T-shaped slot 12. The second insert 305 is inserted into the second T-shaped slot 12 from the side end of the wall 10 to realize the connection between the planting trough 30 and the wall 10.

[0062] Multiple planting troughs 30 located in the same row are all connected to the wall 10 through the same second T-shaped slot 12.

[0063] Specifically, in practical applications, the planting trough 30 is initially positioned by the second T-shaped slot 12, and then the relative fixation between the planting trough 30 and the wall 10 is achieved by concrete pouring and other methods, which can further improve the stability of the planting trough 30 after installation.

[0064] During operation, the vegetation on the planting trough 30 is irrigated by irrigation or by directly using rainwater. The water flows through the planting layer 303 into the ceramsite layer 302, and then flows out through the water outlet 304 at the bottom of the water storage layer 301.

[0065] Multiple streams of water flowing out through multiple outlet holes 304 converge at the outlet gap along the inner wall of the extension bucket 31 and flow down the wall surface of the wall 10 through the outlet gap.

[0066] like Figures 1-5 As shown, the ecological component also includes: a water filter tank 2;

[0067] The filter tank 2 is installed on the back of the wall 10 and corresponds one-to-one with the precast concrete structure 3;

[0068] The opening of the filter trough 2 faces upward, and an inner frame 21 is embedded in the trough. A drain pipe 22 is connected to the bottom of the trough. The drain pipe 22 obliquely penetrates the wall 10 and extends from the bottom of the filter trough 2 to the top of the planting trough 30.

[0069] The back of the wall 10 is adjacent to soil or water.

[0070] like Figures 1-5 As shown, the inner frame 21 is provided with a first filter layer 211, a second filter layer 212 and a third filter layer 213 from bottom to top, forming a reverse filtration module;

[0071] The first filter layer 211 is laid with medium-coarse sand, the second filter layer 212 is laid with sunflower seed chips, and the third filter layer 213 is laid with gravel.

[0072] By setting up a water filter trough 2 in the ecological structure, the water filter trough 2 is used to filter the seepage water from the river channel on the water side or the soil of the enclosure on the soil side, and the filtered water is diverted to the corresponding planting trough 30 through the drainage pipe 22 to irrigate the vegetation in the planting trough 30, so as to realize the reuse of seepage water from the enclosure soil or river water flow and complete the construction of urban ecological civilization.

[0073] It should be noted that the first filter layer 211, the second filter layer 212 and the third filter layer 213 are all covered with reverse filter material, and a three-stage reverse filtration is adopted. The reverse filter material is composed of gravel, pebbles and medium-coarse sand from top to bottom, which has excellent water permeability and filtration performance.

[0074] like Figures 1-5 As shown, a first T-shaped slot 11 is provided on the back of the wall 10, and a first plug 23 that matches the first T-shaped slot 11 is provided in the water filter tank 2. The first plug 23 is inserted into the first T-shaped slot 11 from the side of the wall 10 to realize the connection between the water filter tank 2 and the wall 10.

[0075] The filter tank 2 is initially positioned by the first T-slot 11, and then the filter tank 2 and the wall 10 can be further positioned by concrete pouring or other methods.

[0076] like Figures 1-5 As shown, the filter tank 2 is an inverted trapezoid, which can enhance drainage capacity and prevent water accumulation.

[0077] like Figures 1-5 As shown, the water filter tank 2 uses permeable concrete, which provides structural support, protects the inner filter material, and allows water to pass through.

[0078] The inner frame 21 is made of metal mesh, which has high structural strength and good impact resistance. The metal mesh and the internal three-stage filter material are woven together to form a prefabricated inner filter module.

[0079] It should be noted that the inner frame 21 and the inner filter module are both prefabricated structures, which facilitates mass production and installation;

[0080] The filter tank 2 and the inner frame 21 are fixed together by bolts or other connection methods, resulting in high overall connection strength and the ability to resist large lateral pressure.

[0081] Specifically, when the back of the wall 10 is adjacent to water, the inclination angle of the drain pipe 22 is 4° to 6°;

[0082] By controlling the tilt angle of the drainage pipe 22 to 4° to 6°, the large amount of water flowing through the drainage pipe 22 on the adjacent water side can be controlled to slowly flow into the corresponding planting trough 30, reducing the impact of the water flow on the vegetation. Under normal circumstances, the bottom of the filter trough 2 is higher than the water level on the adjacent water side. Only when the wind and waves impact the river flow will the water level line sway to the position of the filter trough 2 for filtration.

[0083] When the back of the wall 10 is adjacent to the soil, the inclination angle of the drainage pipe 22 is 40° to 50°.

[0084] By controlling the inclination angle of the drainage pipe 22 to 40° to 50°, a small amount of seepage water from the enclosure soil can quickly flow through the drainage pipe 22 into the planting trough 30 after accumulation, facilitating the reuse of seepage water from the enclosure soil.

[0085] In practical applications, flow sensors can be installed at the corresponding drain pipe 22 according to actual needs to monitor the filtration effect and water quality changes in real time, realize intelligent management, and maintain and replace the filter media in a timely manner.

[0086] During operation, a certain number of filter troughs 2 and a corresponding number of precast concrete structures 3 are installed on the wall 10. Then, the vegetation on the planting trough 30 is irrigated by means of irrigation, direct use of rainwater, seepage of the soil after filtration, or use of water flow in the river. The water flows through the planting layer 303 into the ceramsite layer 302, and then flows out through the outlet hole 304 at the bottom of the water storage layer 301.

[0087] Multiple streams of water flowing out through multiple outlet holes 304 converge at the outlet gap along the inclined back plate on the extension bucket 31, and then flow down the wall surface of the wall 10 through the outlet gap, thus completing the construction of urban ecological civilization.

[0088] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0089] 1. In this embodiment of the utility model, the ecological retaining wall is constructed by setting several sets of ecological components on the wall 10. The ecological components are in the form of planting troughs 30 and extension buckets 31. The planting troughs 30 are used to plant vegetation to build an ecological civilization. The extension buckets 31 are used to collect the water flowing out of the water outlet holes 304 at the bottom of the planting troughs 30 to the water outlet gap. Since the water outlet gap is formed by the bottom end of the extension buckets 31 close to the wall 10, the water flowing out of the water outlet holes 304 is collected at the water outlet gap and flows out along the wall 10. This solves the problem that irrigation water is easy to form a flow when discharged through the drainage hole and splashes on the road surface below, thus realizing the effective construction of urban ecological civilization.

[0090] 2. In this embodiment of the utility model, the second T-shaped slot 12 is used to achieve the initial positioning of the planting trough 30, and then the relative fixation between the planting trough 30 and the wall 10 is achieved by means of concrete pouring, which can further improve the stability of the planting trough 30 after installation.

[0091] 3. In this embodiment of the utility model, by setting up a water filter trough 2 on the ecological structure, the water filter trough 2 is used to filter the seepage water from the river on the water side or the soil of the enclosure on the soil side, and the filtered water is diverted to the corresponding planting trough 30 through the drainage pipe 22 to irrigate the vegetation in the planting trough 30, so as to realize the reuse of the seepage water from the enclosure soil or the river water flow, and complete the construction of urban ecological civilization.
