Description

Technical Field

[0001] The utility model belongs to the field of civil engineering construction, in particular to a retaining wall. Background Art

[0002] Retaining walls, as crucial retaining structures in civil engineering, are widely used in scenarios such as highway slopes, riverbanks, and construction pits. Their core function is to resist lateral pressure from the soil, preventing landslides, collapses, and soil erosion. Traditional retaining walls, often constructed with rigid materials such as concrete and stone masonry, offer excellent structural stability but are prone to ecological damage and limited landscape effects, making them inadequate for modern engineering requirements for ecological restoration and sustainable development.

[0003] In recent years, ecological retaining walls have become a research hotspot. These structures integrate multi-layered green planter modules within the wall structure, effectively combining vegetation coverage with engineering protection. These structures often incorporate rainwater collection and storage systems, effectively utilizing natural rainfall for plant irrigation. This reduces maintenance costs, enhances soil and water conservation, and improves the local microclimate.

[0004] However, the existing ecological retaining wall design still has significant defects: although the top external water storage module is convenient for ensuring the water supply of multi-layer planting units through gravitational potential energy, the additional structure not only occupies the plane space, but its additional load is more likely to cause the retaining wall bending moment imbalance, affecting the structural safety; and although the built-in water storage module avoids the load problem and has enough space to set up a larger water storage tank, its position is usually lower than or flush with the multi-layer green plant planting module. As a result, when water resources are scarce, it is inconvenient to supply water to the multi-layer planting units through gravitational potential energy. Usually, it is necessary to transport water upward through mechanical pumping and other methods to ensure the reasonable distribution of water resources in the high-rise planting units, which increases energy consumption and maintenance costs. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies and defects mentioned in the above background technology and provide an ecological retaining wall with good stability and realizing balanced irrigation of multi-layer planting units through gravitational potential energy.

[0006] In order to solve the above technical problems, the technical solutions proposed by the present invention are as follows:

[0007] An ecological retaining wall comprises a retaining wall body and a greening planting module disposed on the side of the retaining wall body facing away from the soil. The greening planting module comprises multiple layers of spaced-apart planting units and a water storage system for evenly irrigating each of the planting units through gravitational potential energy. The water storage system is disposed within the soil on the other side of the retaining wall body and comprises an adjustable water storage device for adjusting the internal water level by volume changes. Placing the water storage system in the soil avoids structural safety and plane space issues for the retaining wall body. The water level is actively controlled by volume changes of the adjustable water storage device to ensure that the water level in the reservoir is higher than the multiple layers of planting units, enabling gravity irrigation without mechanical pumping. Even if the water storage volume decreases, the gravitational potential difference can still be maintained through water level adjustment, solving the problem of high-rise irrigation when the water level in the built-in water storage module is low.

[0008] In the above-mentioned ecological retaining wall, preferably, the adjustable water storage device includes a water tank provided in the soil, a baffle provided in the water tank, and a drive assembly for driving the baffle to move to change the water storage capacity of the water tank. The adjustable water storage device is connected to the plurality of planting units through a gravity irrigation channel. The water storage capacity is precisely controlled by adjusting the baffle by the drive assembly, ensuring that the water level of the water tank can still be maintained above the planting unit under different water conditions, providing a stable potential energy foundation for gravity irrigation and ensuring the balance and reliability of water supply for multi-layer vegetation.

[0009] In the above-mentioned ecological retaining wall, preferably, the water storage tank is a square trough body provided with a top plate, the side close to the retaining wall body is the first side, and the side away from the retaining wall body is the second side, the baffle is a V-shaped baffle that can be folded repeatedly and folded into a V shape, the V-shaped baffle is arranged in the square trough body with the opening facing upward, the two V-shaped sides of the V-shaped baffle are sealed and movably connected to the first side and the second side respectively, and the driving component is arranged at the lower end of the top plate and connected to the two side faces of the opening of the V-shaped baffle. By using a V-shaped foldable baffle, the opening angle of the baffle can be adjusted by the driving component, and the V-shaped baffle is sealed and movably connected to the inner wall of the water storage tank, so as to simply realize stepless control of the water storage volume in the space enclosed by the V-shaped baffle, ensuring that high water level potential energy can be maintained under different water volumes.

[0010] In the above-mentioned ecological retaining wall, preferably, the gravity irrigation channel includes a first drain pipe for draining the water in the V-shaped baffle to the uppermost planting unit by means of gravitational potential energy, and a second drain pipe for draining water to the lower planting unit when the water level of the upper planting unit reaches a preset height. The first drain pipe is arranged obliquely downward between the first side surface and the uppermost planting unit, and the second drain pipe is arranged vertically between adjacent planting units. The inclined first drain pipe can convert the gravitational potential energy into stable water flow power, draining the water in the V-shaped baffle to the uppermost planting unit. After the uppermost planting unit reaches a certain water level, it flows to the lower planting unit through the second drain pipe, ensuring that the water in the water reservoir can automatically and stably flow into each planting unit.

[0011] In the above-mentioned ecological retaining wall, the drive assembly preferably includes two synchronously symmetrically moving telescopic drive members, one end of each of which is hinged to the lower end of the top plate, and the other end of each of which is hinged to the side of the opening of the V-shaped baffle. The synchronously symmetrical telescopic movement of the telescopic drive members can accurately control the folding and opening angles of the V-shaped baffle.

[0012] In the above-mentioned ecological retaining wall, preferably, a pulley is provided on the V-shaped baffle near the top corner of the second side surface, and the second side surface is provided with a curved slide track adapted to the motion trajectory of the pulley. The provision of the pulley allows the V-shaped baffle to maintain the integrity of the sealing surface while, in conjunction with the curved slide track, ensuring smooth volume adjustment along the motion path of the V-shaped baffle.

[0013] In the above-mentioned ecological retaining wall, preferably, a V-shaped water pool is provided in the water reservoir, which is formed by a V-shaped support plate connecting the first side surface and the second side surface. The V-shaped baffle is attached to the inner side of the V-shaped support plate, and gravel is provided between the outer side of the V-shaped support plate and the inner wall of the square trough. The V-shaped support plate and the double walls of the water reservoir form a stable water tank, providing a uniform supporting base for the baffle, and the baffle is attached to the inner side of the support plate when no adjustment is required, which can efficiently transfer the water pressure to the entire water reservoir wall. In addition, the gravel filled between the outer side of the support plate and the pool wall can further improve the overall strength of the retaining wall when it is in a water-deficient state.

[0014] In the above-mentioned ecological retaining wall, preferably, the top plate is provided on the soil surface and has an inner recess, the inner recess having a water collection port located above the opening of the V-shaped baffle, and the water collection port is provided with an isolation net. The inner recess facilitates the diversion and collection of rainwater, which is efficiently introduced into the water storage tank through the water collection port above the opening of the V-shaped baffle, maximizing the capture rate of natural rainfall. The isolation net can intercept solid impurities and biological intrusion, ensuring water cleanliness and eliminating the risk of pipe blockage.

[0015] In the aforementioned ecological retaining wall, the planting unit preferably includes a planting support positioned horizontally on the side of the retaining wall body facing away from the soil, and a plurality of suspended ecological planting troughs mounted on the planting support, the plurality of suspended ecological planting troughs being connected by floating rods. The planting support is fixedly attached to the retaining wall body to form an anti-overturning bearing base, and the plurality of ecological planting troughs are modularly connected by floating rods to form a suspended modular group that adjusts with the water level, achieving adaptive root protection against flooding and facilitating removal and installation of the ecological planting troughs.

[0016] In the above-mentioned ecological retaining wall, preferably, the cross-section of the retaining wall body is an inverted L-shape, and a support base is horizontally provided below the retaining wall body and the adjustable water storage device, and a plurality of limit anchor rods are vertically provided at the lower end of the support base. This arrangement comprises an inverted L-shaped retaining wall body composed of a transverse plate and a vertical plate. The transverse plate is provided on the water storage tank, and the vertical plate provides support for the transverse plate. The transverse plate enhances the stability of the vertical plate when resisting vertical loads. The support base supports and shares the entire load of the upper structure, ensuring the stability and safety of the upper structure. The limit anchor rods penetrate deep into the underground soil to fix and limit the displacement of the structure, thereby further enhancing the overall stability.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] The utility model completely avoids the additional load risk of the external water storage module on the top by embedding the adjustable water storage device into the soil on the back side of the retaining wall through its underground water storage design, ensuring the stability of the structure while releasing surface space. The high water level of the water storage device is maintained by adjustable volume, ensuring that the gravitational potential energy continuously drives the water flow, realizing pump-free balanced irrigation of multi-layer planting units, breaking through the problem of high-rise water supply when the water level of the built-in water storage module is low, significantly reducing operation and maintenance costs, and the overall structure is safe, stable and ecologically sustainable.

[0030] Example:

[0031] like Figures 1 to 4As shown, the ecological retaining wall of this embodiment includes a retaining wall body 2 and a greening planting module located on the side of the retaining wall body 2 facing away from the soil.

[0033] In this embodiment, the water tank 11 is a square trough body provided with a top plate 111. The side thereof close to the retaining wall body 2 is a first side 112, and the side away from the retaining wall body 2 is a second side 113.

In other embodiments, the telescopic drive members 131 can be equipped with electric telescopic rods or the like according to actual conditions.

[0036] In this embodiment, a pulley is provided at the top corner of the V-shaped baffle 12 close to the second side surface 113, and the second side surface 113 is provided with an arc-shaped slide rail 1131 adapted to the motion trajectory of the pulley.

[0037] In this embodiment, a V-shaped water pool is provided in the water storage tank 11, which is formed by a V-shaped support plate 114 connecting the first side 112 and the second side 113. The V-shaped baffle 12 is attached to the inner side of the V-shaped support plate 114, and gravel is provided between the outer side of the V-shaped support plate 114 and the inner wall of the square trough.

[0038] In this embodiment, the top plate 111 is arranged on the soil surface and has an inner concave portion. The inner concave portion is provided with a water collection port 1111 located above the opening of the V-shaped water-blocking plate 12. The water collection port 1111 is provided with an isolation net.

[0039] In this embodiment, a drain pipe 121 connected to the outside of the soil is provided in the V-shaped baffle 12, and a drain valve for controlling its opening and closing is provided on the drain pipe 121. A water level sensor is provided in the water tank 11. When it is detected that the water level exceeds the preset safety threshold, the drain valve will be triggered to open the drain pipe 121 for drainage.

[0040] In this embodiment, the planting unit 3 includes a planting support 31 horizontally disposed on the side of the retaining wall 2 facing away from the soil, and a plurality of suspended ecological greening troughs 32 disposed on the planting support 31. The plurality of suspended ecological greening troughs 32 are connected by floating rods 33. The drainage outlet at the upper end of the second drainage pipe 34 is located at a predetermined height of the planting support 31. When the water level in the planting support 31 reaches this predetermined height, the excess water automatically flows from the second drainage pipe 34 to the underlying planting support 31.

[0041] In this embodiment, the suspended ecological greening trough 32 is equipped with a floating culture box with a geotextile bottom to ensure that the plant roots receive an appropriate amount of water. The planting support 31 is provided with a second drain pipe 34, which drains water downward when the water level in the planting support 31 reaches a preset height. The outlet of the second drain pipe 34 is located at a preset height.

[0042] In this embodiment, the cross-section of the retaining wall body 2 is an inverted L-shape. A supporting base 21 is horizontally provided below the retaining wall body 2 and the adjustable water storage device 1, and a plurality of limiting anchor rods 22 are vertically provided at the lower end of the supporting base 21.

[0043] In this embodiment, asphalt reinforcement and waterproof material are provided between the adjustable water storage device 1 and the retaining wall body 2, which can effectively prevent moisture from penetrating into the inside and outside of the wall.

When irrigation is needed, when the water level detector detects that the water level in the V-shaped baffle 12 is lower than the inlet height of the first drain pipe 14, the telescopic drive member 131 is triggered to contract, causing the V-shaped baffle 12 to fold and contract, and the water storage volume in the V-shaped baffle 12 decreases and the water level rises. When the raised water level exceeds the inlet height of the first drain pipe 14, the stored water begins to flow into the upper planting unit 3 through the first drain pipe 14. After the water level of the upper planting unit 3 reaches its preset height, the excess water flows into the lower planting unit 3 through the second drain pipe 34 for irrigation. After the irrigation is completed, the telescopic drive member 131 extends, drives the V-shaped baffle 12 to unfold, and re-fits with the V-shaped support plate 114, returning to the water storage standby state.
