Description

Technical Field

[0001] This utility model relates to the field of urban landscape design technology, and in particular to an urban landscape ecological landscape design structure. Background Technology

[0002] Urban landscape design refers to the spatial environment within a city that combines natural and artificial elements through design, creation, and management. It includes various forms such as parks, squares, street greening, and residential green spaces. It encompasses the arrangement of various plants (such as trees, flowers, and lawns) and their organic combination with water bodies (such as lakes and streams), architectural features (such as pavilions and sculptures), and roads, aiming to provide urban residents with public spaces that offer multiple functions, including leisure, entertainment, aesthetic appreciation, ecological improvement, and climate regulation.

[0003] Urban landscape ecological design structure refers to the application of ecological principles and methods in urban landscape design to rationally allocate and combine natural elements (such as plants, water bodies, and soil) with artificial elements (such as buildings, roads, and facilities) in the city to form a spatial structure with ecological functions, landscape effects, and social value.

[0004] In existing technologies, traditional urban landscape design mostly adopts a simple combination of hard paving and greening. On the one hand, hard paving covers a large area, making it difficult for rainwater to penetrate, resulting in a large amount of surface runoff. This not only wastes water resources but also increases the pressure on urban drainage systems, exacerbating the risk of urban flooding during heavy rains. On the other hand, traditional greening is inefficient in utilizing water resources, lacking effective rainwater collection and storage mechanisms. Plant growth mainly relies on artificial irrigation, resulting in high water consumption. Therefore, an urban garden ecological landscape design structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an urban garden ecological landscape design structure. The aim is to improve the problems of low water resource utilization efficiency and weak ecological function in some urban landscape design structures in existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An urban garden ecological landscape design structure includes a keel frame, the bottom end of which is detachably connected to a base plate by bolts, an ecological mechanism is provided inside the keel frame, and two vertical greening mechanisms are fixedly connected to the front and rear sides of the keel frame. The ecological structure includes a planting layer, the outer wall of which is fixedly connected to the inner wall of the keel frame, a filter layer fixedly connected to the bottom end of the planting layer, a water storage layer fixedly connected to the bottom end of the filter layer, a landscape surface component fixedly connected to the top end of the keel frame, and a disassembly component fixedly connected to the top end of the keel frame. Through the above technical solutions: the keel frame and chassis can be detachably connected, which facilitates transportation, installation and subsequent maintenance; the internal ecological structure realizes the ecological cycle of rainwater purification, storage and plant growth; the vertical greening structure increases the green area and enhances the three-dimensional effect of the landscape; all parts work together to make the landscape ecological, beautiful and practical.

[0007] As a further description of the above technical solution: The planting layer is 300mm thick and has a porosity of ≥65%. Organic slow-release fertilizer is mixed in the planting layer. The filter layer is 50mm thick and made of coconut coir fiber. The water storage layer is 150mm thick and is made of honeycomb ceramsite with a particle size of 20-30mm. The above technical solutions provide a good growth environment and long-lasting nutrients for plants through the thickness, porosity, and slow-release organic fertilizer of the planting layer; the appropriate thickness of the coconut coir fiber in the filter layer effectively intercepts impurities; and the ceramsite structure and thickness of the water storage layer facilitate large-scale water storage, supplying water to plants through capillary action, improving water resource utilization efficiency, and ensuring plant growth.

[0008] As a further description of the above technical solution: The landscape surface component includes a cover plate, the bottom end of which is fixedly connected to the top of the keel frame. The cover plate has multiple openings inside, and a weathering steel edge strip is fixedly connected to the top outer wall of the cover plate. Through the above technical solution, the cover plate of the landscape surface component has openings to facilitate rainwater to enter the ecological structure. The weather-resistant steel edge strip on the top not only enhances the aesthetics of the landscape, but also protects the edge of the cover plate, extends its service life, and improves the overall quality of the landscape.

[0009] As a further description of the above technical solution: The disassembly and assembly assembly includes multiple buckles, the tops of which are fixedly connected to the bottom of the cover plate. The top of the keel frame has multiple slots, and the outer walls of the buckles engage with the inner walls of the slots. The above technical solution allows for quick installation of cover plates during construction through the use of clips and slots, improving construction efficiency. It also enables convenient replacement of damaged cover plates during later maintenance, reducing maintenance costs and enhancing the maintainability of landscape facilities.

[0010] As a further description of the above technical solution: A sealing layer is filled between the keel frame and the cover plate, and the inner wall of the weathering steel edge strip is in contact with the outer wall of the sealing layer; The above technical solution involves filling a sealing layer between the keel frame and the cover plate, combined with weathering steel edge strips, to effectively prevent rainwater leakage, maintain the internal moisture stability of the ecological structure, protect the keel frame from corrosion, and ensure the reliability and durability of the landscape structure.

[0011] As a further description of the above technical solution: The vertical greening mechanism includes ABS boxes, and multiple ABS boxes are fixedly connected to the front and rear sides of the keel frame on their adjacent sides. Planting troughs are opened inside the ABS boxes. Through the above technical solution, the ABS box of the vertical greening mechanism provides growth space for climbing plants. Multiple boxes are fixed on both sides of the keel frame, increasing the green area, improving the urban ecological environment, and enhancing the three-dimensionality and aesthetics of the landscape.

[0012] As a further description of the above technical solution: A partition is fixedly connected to the inner wall of the planting trough, and a base layer is fixedly connected to the bottom inner wall of the planting trough. The above technical solution involves partitions within the planting trough dividing it into independent spaces, preventing the roots of different climbing plants from tangling, which is conducive to the healthy growth of plant roots. The base layer provides a foundation for plant rooting and facilitates the management and maintenance of different plants.

[0013] As a further description of the above technical solution: The planting trough has a volume of 5L, and the base layer is made of lightweight vermiculite for planting climbing plants; Through the above technical solution: the 5L volume of the planting trough meets the initial growth needs of climbing plants, and the base layer made of lightweight vermiculite has good air permeability and water retention, creating a suitable growth environment for climbing plants, promoting plant growth, and enhancing the effect of vertical greening.

During rainfall, rainwater carries nutrients to nourish the plants, and its porous structure can also initially purify the rainwater. The filter layer is made of 50mm thick coconut coir fiber, which can intercept impurities in the rainwater and prevent them from entering the water storage layer and affecting water storage and quality. The water storage layer is 150mm thick honeycomb-shaped ceramsite with a particle size of 20-30mm, which can store a large amount of rainwater. During drought, it replenishes the planting layer with water through capillary action, realizing the recycling of water resources. Compared with traditional garden landscape design, the comprehensive water saving rate reaches 60%, and the surface runoff is reduced by 80% compared with traditional paving, effectively alleviating urban stormwater pressure, while ensuring plant growth and improving the stability of the ecosystem.

Detailed Implementation

[0018] 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.

[0019] Referring to Figures 1, 2, and 3, one embodiment of this utility model is provided: an urban garden ecological landscape design structure, including a keel frame 1, a base plate 2 detachably connected to the bottom end of the keel frame 1 by bolts, an ecological mechanism 3 disposed inside the keel frame 1, and the front and rear sides of the keel frame 1 being fixed. The structure connects two vertical greening mechanisms 4. The keel frame 1 is made of galvanized steel, which has high strength and corrosion resistance. It serves as the supporting framework for the entire landscape design structure, providing stable support for the ecological mechanism 3, the vertical greening mechanism 4, and the landscape surface components. Its bottom is connected to the base plate 2 by bolts, ensuring the stability of the overall structure and facilitating disassembly and assembly for later maintenance and adjustment. The base plate 2 is made of HDPE material, which has good waterproof performance, effectively preventing water from the ecological mechanism 3 from seeping into the ground and polluting the foundation soil. The ecological mechanism 3 includes a planting layer 301. The outer wall of the planting layer 301 is fixedly connected to the inner wall of the keel frame 1. The planting layer 301 is 300mm thick with a porosity ≥65%. The planting layer 301 contains organic slow-release fertilizer. Its porous structure is conducive to the growth of plant roots, allowing them to take root firmly. The organic slow-release fertilizer can continuously provide nutrients to the plants for a long time. During rainfall, rainwater carries nutrients to moisturize the plants, and its porous structure can also preliminarily purify the rainwater and remove some impurities. A filter layer 302 is fixedly connected to the bottom end. The filter layer 302 is 50mm thick and made of coconut coir fiber. The coconut coir fiber is finely interwoven and can effectively intercept impurities and silt in rainwater. A water storage layer 303 is fixedly connected to the bottom end of the filter layer 302. The water storage layer 303 is 150mm thick and is made of honeycomb ceramsite with a particle size of 20-30mm. It can store a large amount of rainwater. During drought, the stored water is transported upward to the plants in the planting layer 301 by capillary action, realizing the recycling of water resources and ensuring the water supply for plants to maintain growth during periods of water shortage. Specifically, the keel frame 1 is made of galvanized steel, which is high in strength and corrosion-resistant, providing stable support for the ecological structure 3 and the vertical greening structure 4. The bottom is connected to the chassis 2 by bolts, facilitating later maintenance and adjustment. The chassis 2 is made of HDPE material, which has excellent waterproof properties, preventing water leakage from the ecological structure 3 and ensuring the stability of the overall structure. In the ecological structure 3, the planting layer 301 is conducive to plant rooting, and organic slow-release fertilizer continuously provides nutrients; the filter layer 302 purifies rainwater; and the water storage layer 303 stores and recycles water resources, together laying the ecological and structural foundation for the garden landscape and adapting to various scene requirements.

[0020] Reference Figure 2 Figure 3 and Figure 4A landscape surface component is fixedly connected to the top of the keel frame 1. The landscape surface component includes a cover plate 304, the bottom of which is fixedly connected to the top of the keel frame 1. The cover plate 304 has multiple openings 305 inside. Made of GRC material, the cover plate 304 has an opening rate of 40% and a compressive strength ≥25MPa. It covers the top of the keel frame 1, providing protection for the ecological structure 3 below, preventing external debris from entering, and allowing rainwater to flow smoothly through the openings 305. A weathering steel edge strip 306 is fixedly connected to the top outer wall of the cover plate 304, serving a decorative purpose, making the landscape surface more aesthetically pleasing, and protecting the edges of the cover plate 304 from damage due to external impacts. A disassembly assembly is fixedly connected to the top of the keel frame 1, including multiple clips 307. The tops of the clips 307 are fixedly connected to the bottom of the cover plate 304. Multiple slots 308 are opened on the top of the keel frame 1, and the outer walls of the clips 307 engage with the inner walls of the slots 308, facilitating the cover plate 304. The installation and disassembly of the cover plate 304 can be quickly installed or replaced during construction and later maintenance, improving work efficiency. A sealing layer 309 is filled between the keel frame 1 and the cover plate 304. The inner wall of the weathering steel edge strip 306 is in contact with the outer wall of the sealing layer 309. The sealing layer 309 is made of elastic sealant, and its main function is to waterproof and seal, preventing rainwater from leaking from the connection between the keel frame 1 and the cover plate 304, ensuring that the water in the ecological structure 3 does not leak to the outside of the structure, and maintaining the stability of the internal ecosystem. Specifically, the cover plate 304 is made of GRC material, which is pressure resistant and has reasonable openings. It protects the ecological structure 3 and ensures rainwater penetration. The weathering steel edge strip 306 serves both aesthetic and protective purposes for the edges of the cover plate 304. The disassembly and assembly components, consisting of buckles 307 and slots 308, facilitate construction and subsequent maintenance of the cover plate 304. The sealing layer 309 effectively waterproofs and prevents rainwater from leaking from the connection between the keel frame 1 and the cover plate 304, improving the practicality, aesthetics, and durability of the landscape surface. It is suitable for various urban public space garden landscapes.

[0021] Referring to Figures 1 and 2, the vertical greening mechanism 4 includes ABS boxes 401. Multiple ABS boxes 401 are fixedly connected to the front and rear sides of the keel frame 1 on adjacent sides. The ABS boxes 401 are made of sturdy and weather-resistant material, providing growth space for climbing plants. Planting troughs 402 are provided inside the ABS boxes 401, with a volume of 5L. The planting troughs 402 are used to hold planting soil and plant roots. Their 5L volume can meet the initial growth needs of climbing plants. A partition 403 is fixedly connected to the inner wall of the planting trough 402. 403 The planting trough 402 is divided into multiple independent spaces so that the roots of different climbing plants do not interfere with each other and avoid tangling, which is conducive to the healthy growth of plant roots. The bottom inner wall of the planting trough 402 is fixedly connected to the base layer 404, which is made of lightweight vermiculite and is used to plant climbing plants. Lightweight vermiculite has good air permeability and water retention, which allows plant roots to breathe better while maintaining a certain amount of moisture. This ensures that the plants can obtain sufficient oxygen during the growth process without suffering from poor growth due to lack of water, thus promoting healthy plant growth. Specifically, the ABS box body 401 is made of sturdy and weather-resistant material, providing a stable growing space for climbing plants. The 5L capacity planting trough 402 meets the initial growth needs of climbing plants. The partition 403 prevents the roots of different plants from interfering with each other, making maintenance and management easier. The lightweight vermiculite base layer 404 ensures the water and oxygen environment required for plant growth, thus improving the overall effect of vertical greening, improving the urban ecology and microclimate, and is suitable for cities with different climates and various vertical greening scenarios.

[0022] Working Principle: When rainfall occurs, rainwater first enters the ecological structure 3 through multiple openings 305 on the cover plate 304 of the landscape surface component. After entering the planting layer 301, due to the 300mm thickness, porosity ≥65%, and mixture of organic slow-release fertilizer in the planting layer 301, the rainwater can carry the nutrients from the organic slow-release fertilizer during its infiltration, providing water and nutrients for the plants planted in the planting layer 301. At the same time, the porous structure of the planting layer 301 can also play a preliminary purification role for the rainwater. Next, the rainwater continues to infiltrate downwards to the filter layer 302, which is 50mm thick coconut coir fiber. Its fine fiber structure can further filter impurities, silt, etc. in the rainwater, preventing these impurities from entering the water storage layer 303 and affecting the water storage and water quality of the water storage layer 303. The filtered rainwater finally reaches the water storage layer 303, which is 150mm thick. The honeycomb-shaped expanded clay pebbles have a particle size of 20-30mm. This structure has large pores and good water storage capacity, which can store a large amount of rainwater. During drought, the water in the water storage layer 303 will be fed back to the planting layer 301 through capillary action, providing a continuous water supply for the plants and realizing the efficient use and recycling of water resources. The main function of the vertical greening structure 4 is to increase the green area and three-dimensional effect of the urban garden ecological landscape. The planting trough 402 inside its ABS box 401 has a volume of 5L. The bottom inner wall has a base layer 404 made of lightweight vermiculite for planting climbing plants. The partition 403 divides the planting trough 402 into multiple relatively independent spaces to prevent the roots of different climbing plants from intertwining. It also facilitates the management and maintenance of different plants. The lightweight vermiculite base layer 404 has good air permeability and water retention, which can provide a suitable environment for the growth of climbing plants. When rainwater in the ecological structure 3 infiltrates, some of the water will be transferred to the vertical greening structure 4 through the keel frame 1 to provide water for the climbing plants. During the growth process, the climbing plants will climb up along the keel frame 1 to form a three-dimensional green wall landscape, which not only beautifies the urban garden environment, but also improves the urban microclimate to a certain extent, increases air humidity, and reduces temperature.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing 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. 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.
