Description

Technical Field

[0001] This utility model belongs to the field of ecological bank protection technology, specifically relating to a combined ecological wall structure. Background Technology

[0002] With the continuous promotion of social ecological civilization construction, the concept of green development has been deeply integrated into the field of riverbank protection and slope management.

[0003] The ecological functionality and landscape harmony of retaining structures are receiving increasing attention. In recent years, related technologies have been gradually implemented in various engineering scenarios. In the field of urban construction, the application of vertical ecological curtain walls is gaining popularity. Through the coordinated construction of modular green tubes and intelligent irrigation systems, they effectively create a rich and layered three-dimensional green landscape. This approach not only enhances the aesthetics of urban spaces but also strengthens local ecological regulation functions.

[0004] In water conservancy projects and some municipal projects, the ecological frame stacking technology has become the mainstream solution for constructing steep slope retaining walls. By using the staggered platforms between ecological frame components or reserving planting holes on the exterior facade, the cultivation and natural growth of vegetation at the top can be precisely achieved, ensuring the stability of the retaining structure while promoting the natural restoration of the ecosystem in the project area.

[0005] Existing technologies, such as CN112703918A, provide an ecological building wall greening system composed of several vertically arranged units. While it can utilize rainwater to some extent, manual maintenance is still required when rainfall is insufficient. Another existing technology, CN220538542U, provides a hydraulic ecological wall with combined steps outside the supporting wall. Its planting trough is a relatively independent closed unit, hindering nutrient and water exchange with the soil behind the wall. Over time, the plants within the planting trough struggle to continuously replenish nutrients, necessitating manual maintenance to ensure the sustained ecological effect. Utility Model Content

[0006] This utility model provides a combined ecological wall structure, which aims to solve the problem that existing ecological vegetation has difficulty in continuously replenishing nutrients.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a combined ecological wall structure is provided, including a foundation, columns, grating panels, and a backfill layer. At least three columns are provided, all connected to the foundation. The grating panels are connected to the columns, and the grating panels are spaced apart from each other in both the vertical and horizontal directions, with a planting platform formed above each grating panel. The backfill layer is laid on the side of the grating panel away from the planting platform and is connected to the planting platform.

[0008] Preferably, the columns are fixed to the foundation to form a structure supporting the grating panels. The grating panels are spaced apart vertically and horizontally on the columns to form planting platforms. These platforms are used for planting vegetation. A water area is located on one side of the grating panels, and a backfill layer of soil is located on the other side, in contact with the planting platform. This ensures a sufficient supply of water and nutrients for the vegetation on the planting platform.

[0009] Furthermore, the column is a reinforced concrete column or a pipe.

[0010] Preferably, the columns are made of reinforced concrete or pipes and are used to fix and support the grating. Furthermore, the replacement of the columns as needed should also fall within the scope of protection of this application.

[0011] Furthermore, when the column is a reinforced concrete column, the column is rectangular in shape.

[0012] Preferably, the rectangular reinforced concrete columns have a more stable structure to ensure the stability of the grating installation.

[0013] Furthermore, when the column is made of tubular material, the column can be either circular or rectangular.

[0014] Preferably, round, square, or rectangular pipe columns can also provide stable support for the grating. Furthermore, the pipe columns are preferably made of steel.

[0015] Furthermore, the plane of the grating plate is arranged in an I-shape.

[0016] Furthermore, the I-shaped grating plate has mounting holes at both ends, and the column passes through the mounting holes.

[0017] Furthermore, the cross-section of the grating plate is arranged in the shape of a parallelogram, and the included angle of any acute angle of the grating plate with the cross-section of a parallelogram is not less than 60°.

[0018] Preferably, by setting a reasonable aspect ratio of the parallelogram cross section, it is ensured that the upper and lower layer components form a shield after assembly, and no soil leakage occurs.

[0019] Furthermore, the ratio of the horizontal projection length of the long side to the short side of the grid plate with a parallelogram cross-section is greater than the tangent of the acute angle of the grid plate.

[0020] Preferably, by setting the cross-section of the grid plate to a parallelogram, the planting platform is tilted upwards, which can ensure the light conditions for the seedlings.

[0021] Furthermore, it also includes an end mounting block disposed at one end of the grating plate, the upper end of the end mounting block abutting against the upper layer of the grating plate, and the lower end of the end mounting block abutting against the lower layer of the grating plate.

[0022] Preferably, the installation of end mounting blocks satisfies the requirements for structural segmentation and the installation of grating plates at both ends of the revetment.

[0023] Furthermore, the installation spacing between adjacent columns can be adjusted, and the length of the grating plate is set corresponding to the installation spacing.

[0024] Preferably, the length of the grating can be set according to the installation spacing of the columns. Different installation spacing can be adjusted to meet the requirements of bank protection segmentation and shoreline turning. At the same time, different lengths of grating can be adapted to different vegetation and landscaping requirements, thereby setting up planting platforms of different lengths.

[0025] The advantages of this utility model compared with the prior art are as follows: 1. The vegetation is planted directly on the planting platform and is connected to the backfill layer, making it convenient to obtain and replenish nutrients and water, and there are few restrictions on planting vegetation; 2. Adjacent grating plates overlap each other, resulting in good overall integrity and a good forming effect; 3. The columns are inserted into the mounting holes of the grating panels to form an ecological wall. The connection between the upper and lower, and left and right grating panels and the columns makes disassembly and replacement more convenient and allows for reuse. It can be used for both permanent and temporary structures. Attached Figure Description

[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Example 1: See Figures 1 to 2 As shown, this utility model discloses a combined ecological wall structure, including a foundation 1, columns 2, grid panels 3, and a backfill layer 5. There are at least three columns 2, all connected to the foundation 1. The grid panels 3 are connected to the columns 2, and the grid panels 3 are spaced apart from each other in both the vertical and horizontal directions. A planting platform 4 is formed above each grid panel 3. The backfill layer 5 is laid on the side of the grid panel 3 away from the planting platform 4 and is connected to the planting platform 4.

[0030] In this embodiment, the support columns 2 provide a stable support structure for the entire ecological wall. The grid panels 3 are connected to the columns 2, and their spaced arrangement provides space for the planting platforms 4, facilitating vegetation planting. The root system of the vegetation can extend from the planting platform 4 area to the backfill layer 5, further reinforcing the soil's stability and preventing soil erosion. Furthermore, the columns 2 extend into the foundation 1, preferably to a depth of 1 to 3 meters. The depth of the column extension in this application can be adjusted according to actual conditions. Simultaneously, the shorter side length of the grid panel 3 corresponds to the overall width of the ecological wall's grid-type planting platform.

[0031] In some embodiments, the column 2 is a reinforced concrete column or a pipe.

[0032] In this embodiment, the reinforced concrete column has high strength and can withstand the self-weight of the wall and external loads for a long time; the pipe column 2, especially galvanized steel pipe or anti-corrosion pipe, has the advantage of being lightweight and can resist corrosion, thus ensuring the support.

[0033] In some embodiments, when the column 2 is a reinforced concrete column, the column 2 is rectangular.

[0034] In this embodiment, the rectangular concrete column 2 has a certain degree of prefabrication, and can be cast in the factory according to uniform dimensions, which reduces the difficulty of on-site construction.

[0035] In some embodiments, when the column 2 is a pipe, the column 2 is either circular or rectangular.

[0036] In this embodiment, the pipe column 2 has the advantage of being lightweight, which facilitates transportation and makes on-site splicing construction more flexible.

[0037] See Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the plane of the grille 3 is arranged in an I-shape.

[0038] In this embodiment, the I-shaped grating plate 3 has better bending and torsional resistance, thereby improving the overall stability of the support.

[0039] See Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the I-shaped grid plate 3 has mounting holes 6 at both ends, and the column 2 passes through the mounting holes 6.

[0040] In this embodiment, the mounting holes 6 at both ends of the grating plate 3 provide space for the columns 2 to pass through, significantly improving the tightness of the connection between the grating plate 3 and the columns 2 and reducing the risk of loosening. By setting the grating plate 3 in an I-shape, the width at both ends is effectively expanded, reserving space for the mounting holes 6. In addition, the columns 2 are inserted into the grating plate 3 through the mounting holes 6 to form an ecological wall. The columns 2 and the upper and lower grating plates 3 are connected without moisture, making the disassembly of the columns 2 and the grating plate 3 more convenient and facilitating later maintenance. It can be used for both permanent and temporary structures.

[0041] See Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the cross-section of the grid plate 3 is arranged in the shape of a parallelogram, and the included angle of any acute angle of the grid plate 3 with the cross-section of a parallelogram is not less than 60°.

[0042] In this embodiment, by setting the acute angle of the parallelogram to no less than 60°, the problem of concrete chipping and damage caused by an excessively small angle is effectively avoided.

[0043] In some embodiments, the ratio of the horizontal projection length of the long side to the short side of the grid plate 3, which has a parallelogram-shaped cross-section, is greater than the tangent of the acute angle of the grid plate 3.

[0044] In this embodiment, by setting the ratio of the horizontal projection length of the long side to the short side of the parallelogram formed by the cross-section of the grid plate 3 in the installed state to be greater than the acute angle tangent value of the grid plate 3 mentioned above, the lowest point of the upper grid plate 3 is not lower than the highest point of the lower grid plate 3, preventing the formation of soil loss channels. Furthermore, it ensures that the formed planting platform 4 is tilted upwards, guaranteeing adequate light conditions for the seedlings.

[0045] See Figure 8 and Figure 9 As shown, in some embodiments, a mounting block 7 is also provided at one end of the grating plate 3, the upper end of the mounting block 7 abuts against the upper grating plate 3, and the lower end of the mounting block 7 abuts against the lower grating plate 3.

[0046] In this embodiment, there is a gap on the upper and lower sides of the grid plates 3 at both ends. Therefore, the gaps are filled by end mounting blocks 7 to make the installation of the grid plates 3 more stable. In addition, the end mounting blocks 7 are also provided with mounting holes 6 for the insertion of the columns 2.

[0047] In some embodiments, the installation spacing between adjacent columns 2 can be adjusted, and the length of the grating plate 3 is set in accordance with the installation spacing.

[0048] In this embodiment, the installation spacing of the columns 2 is adjusted according to actual needs, and the length of the grating plate 3 is set corresponding to the installation spacing of the columns 2. Therefore, the column spacing can be flexibly adjusted according to the length of the revetment, adapting to segmented revetment structures or revetment curvature. For example, when the straight section of the revetment is 30 meters long, the installation spacing of this section is divided into 1-meter intervals for the columns 2. When the curved section of the revetment is 20 meters long, the installation spacing of the curved section is divided into 0.5-meter intervals for the columns 2, so that the columns 2 and grating plate 3 can better cover the revetment. Furthermore, the curved section of the revetment is divided by drawing the curved section as a curve... See Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the grid plate 3 also has an attachment surface 8 on the side away from the backfill layer 5. Since vines or mosses need to attach to corresponding objects during their growth, the attachment surface 8 on the grid plate 3 provides attachment points for the vegetation. The shape or rough surface on the outer surface of the grid plate 3 can accommodate the climbing of vegetation and the growth of mosses. Preferably, the attachment surface 8 is one type of shape or rough surface. Rough, porous designs, such as natural stone or rough concrete, can provide anchor points for mosses, lichens, and climbing plants, absorbing moisture, dust, and nutrients, which is beneficial for spore germination and root attachment. Concave-convex designs, such as three-dimensional grids or grooves, can provide physical support and climbing guidance for twining vines (such as wisteria and ivy) and creeping plants (such as roses), facilitating manual binding and fixing, and creating microclimate environments. Composite structures, such as three-dimensional mesh or planting troughs, can provide soil or substrate carriers for various plant combinations, herbaceous plants, or hanging plants, fixing root systems and comprehensively supporting multiple growth methods, such as adsorption, twining, and climbing.

[0049] In addition, the width of mosses, lichens and herbaceous plants (such as irises, cannas, and thaliana) is 10cm to 20cm, the width of herbaceous vines (such as morning glories and coral vines) can be 20cm to 30cm, and the width of woody vines (such as roses and ivy) can be 30cm to 50cm.

[0050] Example 2: See Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a combined ecological wall structure, including a foundation 1, which is a concrete structure. The foundation 1 is located at the bottom of the water, and the upper end of the foundation 1 is located at the normal water level. When there are three columns 2, one end of the first grid plate 3 of the first layer is connected to the first column 2, and the other end of the first grid plate 3 is connected to the second column 2; one end of the first grid plate 3 of the second layer is connected to the second column 2, and the other end of the first grid plate 3 is connected to the third column 2; the installation method of the first grid plate 3 of the third layer is the same as that of the first grid plate 3 of the first layer; the installation method of the first grid plate 3 of the fourth layer is the same as that of the first grid plate 3 of the second layer, and so on for the first grid plate 3 of the uppermost layer.

[0051] In addition, a planting platform 4 is provided above each of the first grid plates 3, and the planting platform 4 is used for planting plants.

[0052] Furthermore, a backfill layer 5 is provided within the height range from the foundation 1 to the column 2. The backfill layer 5 is located on the side away from the water area and is soil suitable for planting. The backfill layer 5 extends to the planting platform 4 on the first grid plate 3, thereby facilitating the plants' access to nutrients and water.

[0053] Meanwhile, the grating plate 3 is arranged in an I-shape, with mounting holes 6 at both ends. The size of the mounting holes 6 is larger than the cross-sectional size of the column 2. This eliminates the spacing deviation of the column 2, facilitating installation. Furthermore, the gaps in the mounting holes 6 after installation are filled tightly with sealant. The sealant material is selected according to the actual application, such as concrete, polymer grout, polyurethane filler blocks, gravel, or crushed stone. Moreover, an attachment surface 8 is provided on the side of the grating plate 3 away from the backfill layer 5 for climbing vines or moss to attach to. The attachment surface 8 is preferably a textured surface, but it can also be a rough surface to facilitate plant attachment.

[0054] Example 3: See Figure 1 As shown, when there are four columns 2, one end of the first grid plate 3 of the first layer is installed on the first column 2, and the other end of the first grid plate 3 of the first layer is installed on the second column 2; one end of the second grid plate 3 of the first layer is installed on the third column 2, and the other end of the second grid plate 3 of the first layer is installed on the fourth column 2; one end of the first grid plate 3 of the second layer is connected to the second column 2, and the other end of the first grid plate 3 of the second layer is connected to the third column 2; the installation method of the grid plates 3 of the third and fifth layers and other odd-numbered layers is similar to that of the grid plates 3 of the first layer, and the installation method of the grid plates 3 of the fourth and sixth layers and other even-numbered layers is similar to that of the grid plates 3 of the second layer.

[0055] Example 4: When there are five columns 2, one end of the first grid plate 3 of the first layer is connected to the first column 2, the other end of the first grid plate 3 of the first layer is connected to the second column 2, and one end of the second grid plate 3 of the first layer is connected to the third column 2; the other end of the second grid plate 3 of the first layer is connected to the fourth column 2; one end of the first grid plate 3 of the second layer is connected to the second column 2, the other end of the first grid plate 3 of the second layer is connected to the third column 2, one end of the second grid plate 3 of the second layer is connected to the fourth column 2, and the other end of the second grid plate 3 of the second layer is connected to the fifth column 2; the installation method of the grid plates 3 of the third and fifth layers and other odd-numbered layers is similar to that of the grid plates 3 of the first layer, and the installation method of the grid plates 3 of the fourth and sixth layers and other even-numbered layers is similar to that of the grid plates 3 of the second layer.

[0056] Example 5: When the number of columns 2 is set to five or more, the grid panels 3 shall be installed in sequence according to the above logic.

[0057] Example 6: See Figures 1 to 2 As shown, based on the above embodiment, when the column 2 is constructed of reinforced concrete, the column 2 is rectangular. This facilitates formwork processing, saves processing materials, improves construction efficiency, and is suitable for cast-in-place concrete processes. Compared to circular concrete columns, rectangular concrete column sections make it easier to achieve a regular arrangement of reinforcing bars. The synergistic effect of longitudinal reinforcing bars and stirrups can effectively resist bending and shear stresses, improving seismic performance. Simultaneously, it also facilitates the installation and disassembly of the column 2 and the grating plate 3.

[0058] Example 7: The sides of the grating plate 3 are arranged in a parallelogram shape. The left side of the upper grating plate 3 extends downward to block soil, while the right side of the lower grating plate 3 extends upward to block soil. Furthermore, the vertical height of the left side of the upper grating plate 3 is lower than the vertical height of the right side of the lower grating plate 3.

[0059] In specific implementation of this utility model: On the straight sections of the revetment foundation 1, columns 2 are arranged at equal intervals. On the curved sections of the foundation 1 where the curvature is similar, the arc is divided into multiple equal-length line segments or equal-angle arc segments, and columns 2 are placed at the corresponding positions. Grating plates 3 are installed sequentially from the bottom layer on both the straight and curved sections, and the gaps in the mounting holes 6 are then filled. Simultaneously, the soil for the backfill layer 5 is backfilled. Subsequently, the remaining grating plates 3 are installed sequentially upwards in this manner, and the gaps in the mounting holes 6 are filled, with the soil for the backfill layer 5 being backfilled continuously until the top layer is reached. Additionally, a certain amount of soil for planting is also needed to fill the planting platforms 4 on the grating plates 3. If necessary, gravel is covered on the surface of the planting platforms 4 and the top layer of soil to reduce soil moisture evaporation.

[0060] The advantages of this utility model compared with the prior art are as follows: 1. The vegetation is planted directly on the planting platform and is connected to the backfill layer, making it convenient to obtain and replenish nutrients and water, and there are few restrictions on planting vegetation; 2. Adjacent grating plates overlap each other, resulting in good overall integrity and a good forming effect; 3. The columns are inserted into the mounting holes of the grating panels to form an ecological wall. The connection between the upper and lower, and left and right grating panels and the columns makes disassembly and replacement more convenient and allows for reuse. It can be used for both permanent and temporary structures.

[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
