Description

Technical Field

[0001] The utility model belongs to the technical field of ecological greening, and specifically relates to a settlement-prevention composite planting device for green plant cultivation in collapsible loess areas. Background Art

[0002] In the vast regions of northwest China, north China and other areas, collapsible loess is widely distributed. This type of soil has typical characteristics of water-induced collapsibility and uneven bearing capacity, which brings many challenges to the construction of green plant planting facilities supporting construction projects. With the continuous acceleration of urbanization, the green belts on both sides of urban roads have become an important part of the urban ecological environment. Together with community landscapes and shopping mall greening, they constitute the urban greening system, which not only beautifies the landscape, but also undertakes the core functions of climate regulation and air purification. For construction enterprises undertaking related projects, the stability and adaptability of green plant planting facilities directly determine the quality and ecological value of greening projects;

[0003] At present, most of the traditional green plant planting devices applied in construction projects are ordinary planting pots, brick planting ponds or simple concrete troughs. Such devices are not specially designed for the characteristics of collapsible loess and the special urban environment, and many problems have been exposed in practical applications. Especially in arid and semi-arid areas such as Jinchang, Gansu, the problems are more prominent: Jinchang City is located in the hinterland of the Hexi Corridor, with a dry climate and scarce precipitation. The soil on both sides of the road is heavily polluted, loose in texture, and suffers from severe nutrient loss due to urbanization. However, traditional devices lack rigid bearing frames and deep limit structures. When placed directly on the surface layer of collapsible loess, they are prone to uneven settlement due to the collapsibility caused by soil self-weight compaction and limited irrigation water infiltration, resulting in inclination and cracking of the planting ponds, which not only damages the landscape effect, but also may cause extrusion damage to supporting facilities such as surrounding walkways and pipe networks due to structural instability, increasing the rework and maintenance costs of construction enterprises;

[0004] Therefore, it is necessary to design a settlement-prevention composite planting device for green plant cultivation in collapsible loess areas to solve the above problems. Contents of Utility Model

[0005] In order to solve the problems raised in the above background art, the utility model provides a settlement-prevention composite planting device for green plant cultivation in collapsible loess areas. By adopting this device, a strong skeleton is formed by a honeycomb-type reinforced concrete bearing frame and anti-slip anchors, which effectively resists the uneven settlement of collapsible loess and prevents vegetation from overturning. Combined with a layered structure and multiple anti-loss filter screens, efficient drainage and soil and water conservation are realized, fundamentally avoiding root rot caused by water accumulation and soil loss.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] All standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art. The components used for circuit connection are all conventional models in the prior art.

[0032] Meanwhile, to clearly illustrate the connection relationships and working principles between the components and highlight key points, the accompanying drawings in the instruction manual are organized and drawn in a simplified manner. One simplified diagram can correspond to multiple materials and actual external structural shapes. Example 1

[0033] like Figure 1 As shown;

[0034] A composite planting device for preventing settlement of green plants in collapsible loess areas includes a planting device body 1, a vegetation cultivation cavity 2 opened on the inner surface of the planting device body 1, and several sets of side wall ventilation and water permeability holes 3 evenly opened on the side wall of the planting device body 1.

[0035] This implementation plan addresses the following: Currently, traditional greening devices used in construction projects are mostly ordinary planting pots, brick-built planting beds, or simple concrete troughs. These devices are not specifically designed for the characteristics of collapsible loess and the unique urban environment, leading to numerous problems in practical applications. The problems are particularly pronounced in arid and semi-arid regions such as Jinchang, Gansu. Jinchang City is located in the heart of the Hexi Corridor, with a dry climate and scarce rainfall. The soil along the roads is heavily polluted by urbanization, resulting in loose texture and severe nutrient loss. Traditional devices lack rigid load-bearing frames and depth-limiting structures. When placed directly on the surface of collapsible loess, they are prone to uneven settlement due to soil compaction and limited irrigation water infiltration, causing the planting beds to tilt and crack. This not only damages the landscape but may also cause crushing damage to surrounding walkways, pipelines, and other supporting facilities due to structural instability, increasing rework and repair costs for construction companies. In terms of practical application, this problem is clearly a real and difficult-to-solve issue.

[0036] Furthermore:

[0037] This application incorporates the aforementioned prior art, such as Figures 1 to 5 As shown:

[0038] Based on the above: a composite planting device for preventing settlement of vegetation in collapsible loess areas, wherein the inner surface of the main body 1 of the planting device is provided with a honeycomb reinforced concrete support frame 4 that cooperates with the vegetation cultivation cavity 2, the inner surface of the honeycomb reinforced concrete support frame 4 is fixedly connected with a honeycomb planting substrate support plate 5, the surface of the honeycomb planting substrate support plate 5 is provided with a planting substrate dividing grid plate 6, the interior of the main body 1 of the planting device is provided with a loess filler layer 7, the upper surface of the loess filler layer 7 is provided with a geotextile filter layer 8, and the upper surface of the geotextile filter layer 8 is provided with a gravel permeable layer 9.

[0039] In this implementation plan: The main body 1 of the planting device constitutes the basic container. The sidewall ventilation and drainage holes 3 are used for air exchange and drainage of excess water. The core structure is a honeycomb reinforced concrete load-bearing frame 4 located inside the main body 1, which provides core compressive and bending strength for the entire device. A honeycomb-shaped planting substrate support plate 5 is fixed inside the honeycomb reinforced concrete support frame 4 to directly support the vegetation and upper loads. A planting substrate dividing grid plate 6 is placed on top of the honeycomb planting substrate support plate 5 to divide the planting area into small sections to limit soil displacement. The vegetation cultivation chamber 2 is filled from bottom to top with a layer of loess filler 7, a geotextile filter layer 8, and crushed soil. The permeable stone layer 9 allows for rapid drainage during irrigation or rainwater runoff. The geotextile filter layer 8 prevents particles from the upper loess filler layer 7 from entering and clogging the permeable stone layer 9, ensuring smooth water drainage. By layering the loess filler layer 7, geotextile filter layer 8, and permeable stone layer 9, combined with the limiting and fixing structure of the honeycomb reinforced concrete support frame 4, a stable composite planting foundation is formed. The honeycomb reinforced concrete support frame 4 and the honeycomb planting substrate support plate 5 work together to effectively resist the uneven settlement of collapsible loess. The layered structure ensures smooth drainage, prevents water accumulation from damaging the loess structure, and provides a stable environment for plant growth.

[0040] Furthermore:

[0041] In an optional embodiment, the surface of the honeycomb planting substrate support plate 5 is provided with a plurality of honeycomb buffer filling cavities 10, and the surface of the honeycomb planting substrate support plate 5 is provided with lightweight ceramsite buffer filler 11, which is disposed on the inner surface of the honeycomb planting substrate support plate 5 through the honeycomb buffer filling cavities 10.

[0042] In this embodiment, the honeycomb-shaped buffer filling cavity 10 opened on the honeycomb planting substrate support plate 5 is filled with lightweight ceramsite buffer filler 11. When the device is subjected to external pressure or slight deformation of the foundation, these lightweight ceramsite buffer fillers 11 can generate slight rolling and displacement within the honeycomb-shaped buffer filling cavity 10, absorbing and dispersing stress. The lightweight ceramsite buffer filler 11 not only reduces the self-weight of the device, but the buffer layer it forms can also effectively adapt to the slight deformation of the foundation, avoiding stress concentration that could cause rigid damage to the honeycomb planting substrate support plate 5 and the honeycomb reinforced concrete support frame 4, thus improving the toughness and durability of the device.

[0043] Furthermore:

[0044] In an optional embodiment, the surface of the honeycomb reinforced concrete load-bearing frame 4 is symmetrically fixedly connected with frame handles 12, and the surface of the planting substrate dividing grid plate 6 is provided with grid plate positioning slots 13 that cooperate with the frame handles 12.

[0045] In this embodiment, the frame handle 12 is fixed to the honeycomb reinforced concrete support frame 4, which facilitates the hoisting and transportation of the core component. When the planting substrate separating grid plate 6 is placed on the honeycomb planting substrate support plate 5, the grid plate positioning slot 13 opened on its surface will accurately engage with the frame handle 12, thereby restricting the horizontal movement of the grid plate itself. The frame handle 12 greatly facilitates construction and installation. The cooperation between the grid plate positioning slot 13 and the frame handle 12 ensures the accuracy and fixation of the position of the planting substrate separating grid plate 6, so that its function of separating soil and preventing compaction can be stably performed.

[0046] Furthermore:

[0047] In an optional embodiment, four sets of anti-slip anchors 14 are uniformly fixedly connected to the side of the honeycomb planting substrate support plate 5 away from the frame handle 12, and three sets of anchor anti-slip teeth 15 are uniformly fixedly connected to the surface of the anti-slip anchors 14.

[0048] In this embodiment, multiple sets of anti-slip anchors 14 are fixedly connected to the bottom of the honeycomb planting substrate support plate 5. During installation, these anti-slip anchors 14, together with the core frame, are pressed into the upper gravel permeable layer 9 to achieve initial positioning. The anti-slip teeth 15 on their surface are used to increase the friction with the surrounding soil and rock media, thereby improving safety on slopes or unstable foundations.

[0049] Furthermore:

[0050] In an optional embodiment, several sets of first waterproof soil erosion filter screens 16 are uniformly fixedly connected to the inner side wall of the planting device body 1.

[0051] In this embodiment, the first waterproof soil erosion filter 16 is fixedly covered on the side wall ventilation and water permeability holes 3 on the inner side wall of the planting device body 1. When the internal water is discharged through the side wall ventilation and water permeability holes 3, the first waterproof soil erosion filter 16 effectively blocks the fine particles of the loess filler layer 7 from being lost, maintains soil fertility, and ensures that the side wall ventilation and water permeability holes 3 are not blocked for a long time, thus maintaining the core functions of lateral ventilation and drainage of the device.

[0052] Furthermore:

[0053] In an optional embodiment, a drainage guide slope 17 is provided at the bottom inner side of the planting device body 1, and a bottom drainage hole 18 is provided at the bottom of the planting device body 1. A second waterproof soil erosion filter 19 and a third waterproof soil erosion filter 20 are provided inside the planting device body 1. The second waterproof soil erosion filter 19 and the third waterproof soil erosion filter 20 are fixedly connected to the planting device body 1 through the bottom drainage hole 18.

[0054] In this embodiment: The bottom inner side of the planting device body 1 is designed with a drainage guide slope 17, which can guide the water that seeps into the bottom to the bottom drainage hole 18. At the bottom drainage hole 18, a second waterproof soil erosion filter 19 and a third waterproof soil erosion filter 20 are set to form double protection. The water must pass through these two filter layers before being discharged. The drainage guide slope 17 ensures that there is no water accumulation at the bottom. The double design of the second waterproof soil erosion filter 19 and the third waterproof soil erosion filter 20 provides extremely high reliability, ensuring smooth drainage at the bottom while preventing soil loss to the maximum extent and ensuring the long-term effectiveness of the drainage system.

[0055] Furthermore:

[0056] In an optional embodiment, a device handling handle 21 is symmetrically fixedly connected to the surface of the main body 1 of the planting device.

[0057] In this embodiment, the device handling handle 21 is symmetrically and fixedly connected to the outer surface of the main body 1 of the planting device. It provides a force point for manual or mechanical handling, which greatly improves the convenience and efficiency of the entire planting device during transportation and on-site installation.

[0058] Furthermore:

[0059] In an optional embodiment, a number of bottom support feet 22 are uniformly and fixedly connected to the bottom end of the planting device body 1, and the bottom end of each bottom support foot 22 is fixedly connected to a support foot anti-slip pad 23.

[0060] In this embodiment: the bottom support foot 22 lifts the bottom of the planting device body 1 off the ground, and the support foot anti-slip pad 23 is attached to the bottom end of the bottom support foot 22. It prevents slippage by friction with the contact surface. The bottom support foot 22 creates a bottom ventilation space to prevent moisture accumulation, and the support foot anti-slip pad 23 enhances the stability of the device after placement and prevents accidental movement.

[0061] Furthermore:

[0062] In an optional embodiment, a bottom water collection tray 24 is provided on the lower surface of the planting device body 1.

[0063] In this embodiment, the bottom water collection tray 24 is placed directly below the main body 1 of the planting device to collect excess water from the bottom drainage hole 18 and any water that may seep out from the side wall. The bottom water collection tray 24 collects the drained water to avoid polluting the environment or building surface, and can provide local humidity during evaporation, thus having environmental protection and water-saving benefits.

[0064] Working principle:

[0065] The main body 1 of the planting device is moved to the designated planting location in the collapsible loess area by the device handling handle 21. The device is supported off the ground by the bottom support feet 22. The anti-slip pads 23 of the support feet contact the ground to generate friction and prevent the device from shifting. At the same time, the bottom support feet 22 form a bottom ventilation space. The bottom of the vegetation cultivation chamber 2 of the main body 1 of the planting device is filled with loess filler layer 7. During the filling process, the soil layer is kept flat. Then, the geotextile filter layer 8 is completely laid on the surface of the loess filler layer 7 so that the geotextile filter layer 8 is tightly attached to the loess filler layer 7. Then, the gravel permeable layer 9 is laid on the surface of the geotextile filter layer 8 to form a bottom composite structure of loess, filter and permeable.

[0066] The core support unit is carried by the frame handle 12 on the surface of the honeycomb reinforced concrete load-bearing frame 4. The unit is placed into the vegetation cultivation cavity 2 of the main body of the planting device 1. The anti-slip anchor 14 is aligned with the gravel permeable layer 9 and pressed down. The anti-slip anchor 14, with the anchor anti-slip teeth 15, is inserted into the gravel permeable layer 9. The anchor anti-slip teeth 15 are engaged with the gravel particles to achieve limiting, thus completing the positioning and fixing of the core support unit.

[0067] The planting substrate dividing grid plate 6 is placed on the surface of the honeycomb planting substrate support plate 5, so that the grid plate positioning groove 13 on the surface of the planting substrate dividing grid plate 6 is precisely matched with the frame handle 12 on the honeycomb reinforced concrete support frame 4. The planting substrate dividing grid plate 6 is fastened to the frame handle 12 through the grid plate positioning groove 13, thereby achieving horizontal limiting and fixing, preventing the planting substrate dividing grid plate 6 from shifting. Planting substrate is filled into the area divided by the planting substrate dividing grid plate 6. The planting substrate dividing grid plate 6 divides the planting substrate into small pieces, restricting substrate displacement.

[0068] After filling, green plants are planted in the planting substrate, completing the planting preparation. During irrigation or rainfall, water first permeates to the planting substrate layer, then penetrates downwards through the gaps in the planting substrate dividing grid plate 6 to the honeycomb planting substrate support plate 5. The honeycomb structure of the honeycomb planting substrate support plate 5 allows water to continue to permeate downwards to the gravel permeable layer 9. The gravel permeable layer 9 quickly drains water, preventing water accumulation. During the downward permeation process, the geotextile filter layer 8 blocks particles from the loess filler layer 7 from entering the gravel permeable layer 9, preventing the gravel layer from becoming clogged. This ensures that water can smoothly penetrate downwards or flow to both sides. Water flowing laterally is discharged through the ventilation and water permeability holes 3 on the side wall of the main body 1 of the planting device. The first soil erosion filter 16 prevents the planting substrate and loess particles from being lost with the water, while also enabling air exchange between the vegetation cultivation chamber 2 and the outside. Water flowing downwards is guided by the drainage guide slope 17 at the bottom of the inner side of the main body 1 of the planting device and gathers at the bottom drainage hole 18. After being filtered twice by the second soil erosion filter 19 and the third soil erosion filter 20, it is discharged to prevent soil particles from being lost.

[0069] The discharged water falls into the bottom water collection tray 24 on the lower surface of the main body 1 of the planting device and is collected. This not only prevents water from directly seeping into the collapsible loess below and causing soil subsidence, but also allows for recycling. When water evaporates, the bottom water collection tray 24 can also provide local humidity to the surrounding area of ​​the device, improving the growth environment for green plants. When the growth of green plants causes root expansion or the collapsible loess settles, the lightweight ceramsite buffer filler 11 in the honeycomb planting substrate support plate 5 generates slight rolling and displacement within the honeycomb buffer filling cavity 10, absorbing and dispersing stress, and preventing damage to the honeycomb planting substrate support plate 5 and the honeycomb reinforced concrete support frame 4 due to stress concentration. At the same time, the anti-slip teeth 15 on the surface of the anti-slip anchor 14 tightly engage with the gravel permeable layer 9, restricting the lateral movement of the core support unit. The honeycomb reinforced concrete support frame 4 and the honeycomb planting substrate support plate 5 work together to resist uneven settlement and ensure the overall stability of the device.
