Description

Technical Field

[0001] This invention relates to the field of greening engineering technology, specifically to a terraced landscape wall embedded layered planting trough device suitable for harsh environments such as high altitude and repeated freeze-thaw cycles. Background Technology

[0002] Terraced landscape walls, serving as both structural slope protection and vertical greening functions, are widely used in municipal landscaping, ecological restoration, and building facade greening. They typically involve layering planting troughs on the wall to create progressively receding green terraces, achieving both vertical planting and aesthetic enhancement.

[0003] However, when terraced landscape wall planting trough devices are applied to high-altitude, cold regions, the following problems arise:

[0004] First, irrigation maintenance is difficult and the maintenance cost is high: transportation is inconvenient and manpower is scarce in high-altitude areas. Traditional drip irrigation or sprinkler irrigation systems rely on pipe networks and power equipment, which are complicated to install. The pipelines are prone to failure due to freezing and blockage. The subsequent maintenance is frequent and costly, making it difficult to achieve long-term maintenance-free operation.

[0005] Second, severe freeze-thaw damage and short structural life: repeated freeze-thaw cycles are the main cause of cracking, deformation and detachment of planting troughs and their auxiliary components. Currently, most of them are made of concrete, ordinary plastic or metal parts in one piece. When drainage is not smooth, water in the trough freezes and expands, which can easily crack the trough. In addition, weak parts such as pipe joints and metal connectors deteriorate faster under freeze-thaw cycles, which greatly shortens the service life of the facilities.

[0006] Third, the conflict between preventing blockage and drainage is difficult to resolve: traditional planting troughs have drainage holes at the bottom, which are easily blocked by soil during long-term use, leading to water accumulation, root rot, or waterlogging due to freezing; while increasing the size of the drainage holes can lead to soil erosion. The geotextile laying method also has the problems of poor fit with the trough body and inconvenience in cleaning and replacement. Summary of the Invention

[0007] The present invention adopts the following technical solution: an embedded layered planting device for terraced landscape walls, comprising: a support frame, a planting box, a planting bag, and a drainage device;

[0008] The support frame is provided with multiple sets of hanging parts layer by layer, and each set of hanging parts is provided with a planting box and a drainage device that can be detached from the top and bottom respectively;

[0009] The planting box is detachably equipped with a planting bag;

[0010] The drainage device includes a water storage tank and a drainage core. The water storage tank is detachably mounted on the hanging part and is located below the planting box.

[0011] One end of the drainage core is placed inside the water storage tank, and the other end of the drainage core extends into the planting box below.

[0012] Furthermore, the bottom of the planting box is provided with a first bending plate on each side, and the first bending plate is snapped onto the hanging part.

[0013] Furthermore, the top two sides of the planting box are respectively provided with limiting grooves, and the two ends of the planting bag are respectively provided with limiting handles, and the limiting grooves accommodate the limiting handles.

[0014] Furthermore, a second bending plate is provided on each of the bottom sides of the water storage tank, and the second bending plate is snapped onto the hanging part.

[0015] Furthermore, the water storage tank has a centrally recessed structure, a drainage hole communicating with the interior of the water storage tank is provided on one side of the water storage tank, a storage hole is provided on the other side of the water storage tank, and an installation ring is provided at the inner bottom of the water storage tank.

[0016] Furthermore, the height of the storage hole is higher than the height of the drainage hole.

[0017] Furthermore, one end of the drainage core is inserted into the mounting ring, and the other end of the drainage core passes through the placement hole and the side wall of the planting box and extends to the inner bottom of the planting box. The drainage core located inside the planting box is multi-stranded.

[0018] Furthermore, an independent drainage device is provided on the side of the top planting box, and the drainage core of the drainage device extends downward into the top planting box.

[0019] Furthermore, the bottom of the planting box has multiple through holes, the water storage tank is located directly below the planting box, the bottom of the support frame is provided with a support column, the water storage tank has a V-shaped cross section, the planting bag is made of non-woven fabric, the drainage core is made of synthetic fiber non-woven fabric, and the planting box is rotomolded.

[0020] How to use the embedded layered planting device for terraced landscape walls:

[0021] Rainwater falls into the planting pockets of each layer of planting boxes. Some of the rainwater is absorbed by the soil, while the excess water penetrates the planting pockets under the action of gravity, collects at the bottom of the planting box, and is quickly discharged through multiple holes. The water discharged from the upper planting box drips precisely into the lower water storage tank.

[0022] After water droplets fall into the water storage tank, they are preferentially absorbed by the end of the drainage core fixed at the installation ring. Based on capillary action, the water is continuously transported upward along the fiber gaps of the drainage core, passes through the placement hole and enters the lower planting box. The end of the drainage core disperses into multiple strands inside the planting box and adheres to the bottom of the planting bag over a large area. Through the permeable wall of the planting bag, the water is evenly and slowly released back into the soil for the plant roots to absorb.

[0023] When rainfall is heavy, the water level in the storage tank exceeds the height of the drain hole, and the excess water overflows from the drain hole and falls to the ground.

[0024] The present invention has the following beneficial effects: by setting up a diversion structure, water supply is achieved, effectively solving the problem of difficult traditional irrigation and maintenance; on the other hand, the V-shaped trough structure design avoids freezing and cracking of the water storage tank; and by setting up planting bags, rapid drainage is achieved while intercepting soil particles, avoiding the problems of drainage hole blockage and soil erosion.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figures 1 to 4 As shown in the figure, an embedded layered planting trough structure for a terraced landscape wall according to an embodiment of the present invention includes: a support frame 1, a planting box 2, a planting sack 3, and a drainage device 4.

[0034] The support frame 1 is provided with multiple hanging parts 11 that advance layer by layer. Each group of hanging parts 11 is provided with a planting box 2 and a drainage device 4 that can be detached from the top and bottom. The planting box 2 is provided with a planting bag 3 that can be detached from the bottom.

[0035] The bottom of the support frame 1 is inclined with a guide platform, so that all the water overflowing from the water storage tank 41 eventually falls into the guide platform and is discharged to the ground, avoiding dripping water into the soil under the support frame 1 and causing collapse or other situations.

[0036] The bottom of the support frame 1 is provided with a plurality of support columns 12, which are installed in the ground to fix the invention.

[0037] The bottom sides of the planting box 2 are respectively provided with first bending plates 21, which are snapped onto the hanging part 11 for easy disassembly and installation.

[0038] The cross-sections of the first bending plate 21 and the second bending plate 411 are both fan-shaped, and both are made of hot-dip galvanized steel sheet, which has good safety and durability.

[0039] The top two sides of the planting box 2 are respectively provided with limiting grooves 22, and the two ends of the planting bag 3 are respectively provided with limiting handles 31. The planting bag 3 is installed in the planting box 2 through the limiting handles 31 and the limiting grooves 22, which facilitates disassembly and installation. The planting bag 3 is made of non-woven fabric that is permeable to water but not soil, which can achieve rapid drainage while intercepting soil particles, preventing the drainage hole 412 from being blocked and soil and water loss, and making it easy to lift and replace as a whole.

[0040] The top of the planting box 2 is provided with limiting grooves 22 on both sides, and the planting bag 3 is provided with limiting handles 31 on both sides. The planting bag 3 is installed in the planting box 2 by the limiting handles 31 and the limiting grooves 22 to prevent the sides of the planting bag 3 from falling due to the weight of the soil inside.

[0041] The planting box 2 is integrally rotomolded from frost-resistant and weather-resistant material. Multiple through holes 23 are provided at the bottom of the box. The water storage tank 41 is located directly below the planting box 2, eliminating the risk of seam cracking, providing multiple drainage redundancies, and ensuring that the upper drainage accurately drips into the lower water storage tank 41.

[0042] There is a certain gap between the hanging part 11 at the bottom of the planting box 2 and the water storage tank 41, so that the water storage tank 41 can be disassembled. The height of the gap is at least enough to allow the water storage tank 41 to pass through. The drainage device 4 includes: the water storage tank 41 and the drainage core 42.

[0043] The water storage tank 41 is detachably mounted on the hanging part 11 and located below the planting box 2. One end of the drainage core 42 is located inside the water storage tank 41, and the other end extends into the planting box 2 below.

[0044] A filter is installed on the inner wall of the water storage tank 41. The filter is located above the storage hole 413 to intercept impurities carried in the upper dripping water, protect the flow core 42 from being blocked, and keep the water storage area clean.

[0045] The bottom sides of the water storage tank 41 are respectively provided with second bending plates 411, which are snapped onto the hanging part 11 for easy disassembly and installation.

[0046] The interior of the water storage tank 41 is a recessed tank, and a drain hole 412 communicating with the interior is provided on one side of the water storage tank 41, and a placement hole 413 is provided on the other side. An installation ring 414 is provided at the bottom of the water storage tank 41. When freezing, the V-shaped tank guides the ice layer to float upward to release stress and prevent freezing and cracking, while controlling the water level and fixing the diversion core 42.

[0047] The height of the storage hole 413 is higher than that of the drain hole 412, ensuring that overflow water is discharged from the drain hole 412 without submerging the storage hole 413, and protecting the area where the drain core 42 is inserted from contamination by floating impurities.

[0048] The drainage core 42 is made of synthetic fiber non-woven fabric. One end of it is inserted into the mounting ring 414, and the other end passes through the placement hole 413 and the side wall of the planting box 2 and extends to the inner bottom of the planting box 2. The drainage core 42 located in the planting box 2 is configured to be dispersed into multiple strands to achieve efficient capillary water conduction, increase the contact area with the planting pouch 3, and make water conduction more uniform and reliable.

[0049] Rubber rings are provided on the drainage core 42 located in the placement hole 413 and on the drainage core 42 located on the side wall of the planting box 2, respectively, to seal the gap between the drainage core 42 and the hole wall, prevent soil and water leakage, and protect the drainage core 42 from wear.

[0050] An independent water diversion device 4 is provided on one side of the topmost planting box 2. The water diversion core 42 of the device 4 extends downward into the topmost planting box 2 to provide the initial water source for the entire passive irrigation system, enabling the entire system to be watered without manual watering.

[0051] When it rains naturally, the rainwater first falls into the planting pockets 3 of each planting box 2. Some of the rainwater is absorbed by the soil, and the excess water penetrates the planting pockets 3 under the action of gravity, collects at the bottom of the planting box 2, and is quickly discharged through multiple through holes 23. The water discharged from the upper planting box 2 drips precisely into the lower water storage tank 41 because the water storage tank 41 is located directly below it.

[0052] After water droplets fall into the water storage tank 41, they are preferentially absorbed by the end of the drainage core 42 fixed at the mounting ring 414. Based on capillary action, the water is continuously transported upward along the fiber gaps of the drainage core 42, passes through the placement hole 413 and enters the lower planting box 2. The end of the drainage core 42 disperses into multiple strands inside the planting box 2 and adheres to the bottom of the planting bag 3 over a large area. Through the permeable wall of the planting bag 3, the water is evenly and slowly released back into the soil for the plant roots to absorb.

[0053] The above process is autonomously regulated by the soil's moisture content: when the soil is dry, capillary suction is enhanced, and water replenishment is accelerated; when the soil is moist, water replenishment is automatically slowed down or stopped, thus achieving on-demand water supply.

[0054] When the rainfall is heavy and the water level in the water storage tank 41 exceeds the height of the drain hole 412, the excess water overflows from the drain hole 412 and eventually falls to the ground.

[0055] In summary, the terraced landscape wall embedded layered planting trough device provided by the present invention, on the one hand, by setting up the diversion device 4, when the soil in the planting pocket 3 is dry, the capillary suction is enhanced, and the diversion core 42 can introduce water into the soil. When the soil is moist, the water replenishment is automatically slowed down or stopped, realizing "on-demand water supply", thereby solving the difficulties of traditional irrigation and maintenance. On the other hand, the V-shaped trough design avoids the freezing and cracking of the water storage tank 41. Furthermore, the planting pocket 3, made of water-permeable but soil-impermeable non-woven fabric, achieves rapid drainage while intercepting soil particles, avoiding the problems of clogging of the drainage hole 412 and soil erosion.
