Abstract
Description
Technical Field
[0001] This utility model belongs to the field of retaining wall technology, specifically relating to an eco-friendly retaining wall protection structure. Background Technology
[0002] With the development of society, economy, and culture, people's needs for retaining walls have expanded beyond mere protection to include harmony between humanity and nature, leading to continuous exploration of green and low-carbon construction methods. Traditional gravity retaining walls rely on their own weight for stability, requiring large quantities of structural materials and offering only protection, failing to meet the high-quality construction requirements of resource conservation and energy efficiency. Therefore, reinforced concrete piles have begun to be used for retaining walls, specifically sheet pile retaining walls. The structure of the piles has gradually upgraded from cast-in-place piles to prestressed concrete piles. These prestressed concrete piles are interconnected via tenon joints and driven closely into the foundation to form the retaining wall, significantly reducing material consumption per unit length of enclosure. From a resource conservation perspective, this aligns with the requirements of low-carbon development. However, the water-facing side of the retaining wall formed by reinforced concrete piles remains gray concrete, which is aesthetically unsatisfactory. In water-related projects, it isolates the interaction channel between water and soil, impacting the living environment of riparian organisms, hindering natural water interaction, reducing the ecological integrity of the treated riparian environment, and limiting further application scenarios. Therefore, it is necessary to upgrade the functions of existing sheet pile retaining walls to meet the needs of ecological governance.
[0003] In the prior art, as disclosed in the Chinese utility model patent "A Vertical Greening Pile Plate Wall" with the patent number ZL201620717165.5, a vertical greening pile plate wall is disclosed. By introducing the concept of vertical greening and making full use of the vertical space in front of the retaining plate between two anti-slide piles, multiple obtuse flange plates are arranged in layers on the vertical retaining wall to form multiple vertical planting grooves. Multiple drainage holes are provided on the retaining plate above each layer of the planting groove and are matched with the planting groove of this layer, achieving the organic combination of the engineering protection of the pile plate wall and vertical ecological greening. Another example is the Chinese utility model patent "A Pile Plate Wall Support Structure with Ecological Protection Function" with the patent number ZL 201721781479.2, which discloses a pile plate wall support structure with ecological protection function, including anti-slide piles and precast retaining plates. The two ends of the retaining plate are supported on the pile body of the anti-slide pile. The retaining plate includes a solid retaining plate and a hollow retaining plate. An ecological bag is arranged behind the hollow retaining plate. The hollow retaining plate includes a hollow retaining plate skeleton and hollow retaining plate holes arranged in the hollow retaining plate skeleton. A filter layer is arranged between the retaining plate and the backfill soil. The filter layer includes a double-layer geotextile and filter material filled between the double-layer geotextile. The hollow retaining plate holes are the drainage channels of the pile plate wall, and the ecological bag behind the hollow retaining plate realizes greening. The drainage channel reduces the artificial maintenance of vegetation. In the above technical methods, the long-term growth of vegetation depends on the replenishment of moisture in the back soil mass, and it is isolated from the circulation system of the natural environment, still having certain deficiencies in ecological maintenance and conservation. Utility Model Content
[0004] In view of the problems existing in the above prior art, the present utility model provides an ecological and environment-friendly retaining wall protection structure, which has a simple structure, strong versatility, good economy, is conducive to ecological maintenance and conservation, and is convenient for large-scale application and promotion.
[0005] To achieve the above object, the present invention is realized through the following technical solutions:
[0006] An ecological and environment-friendly retaining wall protection structure includes support piles and retaining plates arranged between adjacent support piles. The retaining plate includes a first retaining plate and a second retaining plate. The second retaining plate includes a planting groove and a side plate for lapping with the support pile. The planting groove is a protruding trapezoidal structure. The side plate is arranged at the bottom of both sides of the planting groove. The cross-section of the second retaining plate is in a "U" shape. The first retaining plate is a flat plate and is arranged at the top of the side plate.
[0007] Further, the top of the planting groove is higher than the top of the side plate.
[0008] Further, a coping beam is arranged at the top of the support pile. The top surface of the first retaining plate is not lower than the bottom surface of the coping beam of the support pile and not higher than the top surface of the coping beam.
[0009] Furthermore, the top surface of the planting trough is higher than the normal water level of the river and the foundation soil surface within the planting trough.
[0010] Furthermore, the side plates of the first and second retaining plates are flat surfaces on which the support piles rest.
[0011] Furthermore, water-stop grooves are provided on the side plates of the first and second retaining plates and the bearing surfaces of the support piles, and water-stop strips are pasted or mortar is injected into the water-stop grooves, or matching tenon structures are provided on the side plates of the first and second retaining plates and the bearing surfaces of the support piles.
[0012] Furthermore, the bottom of the second retaining plate is wedge-shaped.
[0013] Furthermore, a drainage channel is provided on the first retaining plate, and a biological hole and a drainage channel are provided on the second retaining plate. The diameter of the biological hole on the water-facing side is smaller than the diameter on the soil-facing side, and it slopes downward from the water-facing side to the soil-facing side.
[0014] Furthermore, the top wall thickness of the planting trough is increased by 10-50 cm.
[0015] Furthermore, the first and second retaining plates are separate units. The upper surface of the side plate of the second retaining plate is a slope, and the height of the soil-facing side is greater than the height of the other side. The bottom of the first retaining plate is also provided with a matching slope.
[0016] Furthermore, the first and second retaining plates are integral.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model provides an eco-friendly retaining wall protection structure. The planting trough formed by the misalignment of the first and second retaining plates allows the soil to be directly connected to the foundation behind the retaining plates, integrating with the underlying ecosystem. This is beneficial for the ecological preservation and maintenance of the bank slope, making it more environmentally friendly. The top surface of the planting trough is higher than the river water level and also higher than the inner foundation soil surface, effectively preventing erosion of the soil foundation by rainwater, waves, or floodwaters, thus effectively controlling soil erosion. Furthermore, biological holes and drainage channels can be installed outside the planting trough to ensure habitat for aquatic organisms and energy exchange between the inside and outside, minimizing the impact on the aquatic ecological environment.

[0032] The specific embodiments of this utility model will be further explained below with reference to the accompanying drawings.
[0033] like Figures 1-8 As shown, an eco-friendly retaining wall protection structure includes support piles 1 and retaining plates. The support piles 1 are spaced apart in the bank slope foundation, and the retaining plates are placed between adjacent support piles 1 to form a complete bank slope retaining wall protection structure.
[0034] The retaining plate has one side facing the soil and one side not facing the soil, including a first retaining plate 2 and a second retaining plate 3. The first retaining plate 2 is disposed on the upper side of the second retaining plate 3, such as... Figures 2-3 .
[0035] Specifically, the second retaining plate 3 includes a planting groove 3-1 and side plates 3-2. The planting groove 3-1 is a trapezoidal structure protruding towards the non-soil-facing side. The side plates 3-2 are arranged at the bottoms of both sides of the planting groove 3-1 for lapping with the retaining pile 1. The cross-section of the second retaining plate 3 is in a "U" shape. The width of the second retaining plate 3 is greater than the spacing between adjacent retaining piles 1, and it is preferably more than 50 mm. The top surface of the planting groove 3-1 is higher than the top surface of the side plates 3-2, which is convenient for arranging the first retaining plate 2.
[0036] The first retaining plate 2 is a flat plate structure, preferably a rectangular flat plate. The first retaining plate 2 is arranged at the top of the side plates 3-2 of the second retaining plate 3. Since the soil-facing side of the planting groove 3-1 of the second retaining plate 3 is outside the outer surface of the first retaining plate 2, there is a dislocation between the two, thus forming a planting groove 3-1 where vegetation can be planted. In the planting groove 3-1, vegetation can be planted by sowing, planting, etc. Moreover, due to the dislocation between the two, the vegetation is equivalent to being directly planted on the foundation soil behind the retaining plate, integrating with the rear ecosystem. The moisture and nutrients of the vegetation can be directly obtained, which is more ecological and environmentally friendly. Decorative textures can also be set on the outer surface of the planting groove 3-1 to be more beautiful and achieve harmony with the environment.
[0037] To ensure the safety of the bank slope, a coping beam is arranged at the top of the retaining pile 1. The top surface of the first retaining plate 2 is not lower than the bottom surface of the coping beam of the retaining pile 1 and not higher than the top surface of the coping beam.
[0038] At the same time, to ensure the safety of the vegetation in the planting groove 3-1, the top surface of the planting groove 3-1 is higher than the river water level and higher than the inner foundation soil surface, preventing the scouring of the soil foundation by rainwater, wind waves or river water during the flood period, and effectively controlling soil erosion.
[0039] Furthermore, to better protect the ecological environment of the bank slope, ensure the habitat of aquatic organisms and the internal and external energy interaction, and minimize the impact on the water ecological environment, a drainage channel 5 is arranged on the first retaining plate 2, and biological holes 4 and drainage channels 5 can be arranged on the second retaining plate 3. The drainage channel 5 can adopt pre-buried permeable concrete blocks or PVC pipes. The biological holes 4 are reserved holes with a slope that slopes downward from the water-facing side to the soil-facing side. The aperture on the water-facing side is smaller than the aperture on the soil-facing side, and the highest point of the soil-side hole opening is lower than the lowest point of the outer-side hole opening. The biological holes are smaller on the water-facing side and larger on the soil-facing side, which can expand the actual living space of aquatic organisms, and at the same time, the hole size can effectively limit the harassment of natural enemies.
[0040] The surfaces of the first retaining plate 2 and the side plates 3-2 of the second retaining plate 3 can be set as flat surfaces, which are suitable for most retaining piles and have a high adaptability. For example Figure 6As shown, to prevent soil leakage from the retaining plate, corresponding water-stop grooves can be set on the surface of the first retaining plate 2 and the surface of the side plate 3-2 of the second retaining plate 3. Water-swellable sealing strips can be pasted or mortar can be injected into the water-stop grooves, such as... Figure 7 As shown, alternatively, a groove can be provided on the soil-facing surface of the support pile 1, and corresponding tenons that fit the groove can be provided on the surface of the first retaining plate 2 and at the corresponding positions on the side plate 3-2 of the second retaining plate 3. The connection is achieved through the interlocking of the tenons and mortises, such as... Figure 8 As shown.
[0041] Because the second retaining plate 3 is inserted into the soil by mechanical equipment during construction, the top wall thickness of the planting trough 3-1 of the second retaining plate 3 can be increased by 10 to 50 cm to prevent damage during clamping.
[0042] In addition, the bottom of the second retaining plate 3 can be set as a wedge shape, which is convenient for driving into the foundation and helps to fit with the support pile 1.
[0043] It should be noted that the first retaining plate 2 and the second retaining plate 3 can be of the aforementioned split type. Split-type construction simplifies mold making and facilitates production and hoisting. For example... Figures 4-5 As shown, when made in a split configuration, the upper surface of the side plate 3-2 of the second retaining plate 3 is inclined, with the height of the side facing the soil greater than the height of the other side. The bottom surface of the first retaining plate has a matching inclined surface. The advantage of this design is that after installation, the compression of the soil behind it can maintain the stability of the protective structure. The bottom surface of the first retaining plate and the top surface of the second retaining plate have slopes towards the water (or open) surface, mainly to prevent the first retaining plate from tipping over during construction and installation. It can also be made as a single unit, i.e., prefabricated as a whole, such as... Figures 2-3 As shown, this is more conducive to speeding up the construction progress and strengthening the overall strength.
[0044] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
