Technical Field
[0001] This utility model relates to the field of urban landscape design technology, and in particular to a solid waste recycled green space rainwater storage unit and a storage system, collection system and plant irrigation system using the storage unit. Background Technology
[0002] Solid waste recycling green space refers to the transformation of areas that were originally polluted by solid waste or where solid waste was piled up (such as landfills, industrial waste dumps, abandoned mining areas, etc.) into green spaces with ecological, landscape, and recreational functions.
[0003] Solid waste recycling green spaces have the following drawbacks:
[0004] 1. The soil volume in the solid waste recycled green space is small and cannot retain water. The water and nutrients needed by the plants are easily lost. It is necessary to lay devices to store water and nutrients in the piled-up green space.
[0005] 2. Most ordinary green spaces currently use water storage ponds to collect rainwater, but the terrain stability of green spaces generated from solid waste is poor, especially the bearing capacity of the green planting slopes is weak. Water storage ponds are mostly built with concrete, stone, and brick, so they are not suitable for green spaces generated from solid waste.
[0006] 3. From a construction perspective, installing water storage tanks at solid waste recycling sites is difficult, and large-area tanks can negatively impact the paving of above-ground green spaces and vegetation growth. Maintenance often requires damaging large areas of green space, and it takes a considerable amount of time for the green spaces to recover after repaving.
[0007] 4. The existing water storage model of solid waste recycling sites has a small water storage capacity and limited application, which cannot realize the urban construction layout of "building a sponge city". Utility Model Content
[0008] The purpose of this utility model is to solve the above problems by providing a rainwater storage unit for solid waste recycled green space and a storage system, collection system and plant irrigation system using the storage unit. By constructing a storage system in solid waste recycled green space and collecting rainwater, a water source is provided for subsequent irrigation, thus forming a virtuous cycle of water resources in solid waste recycled green space.

[0044] The following detailed description, in conjunction with the accompanying drawings, describes the specific implementation of a solid waste recycling green space rainwater storage unit of this utility model, as well as the storage system, collection system, and plant irrigation system using the storage unit, for rainwater collection, storage, and irrigation.
[0045] See appendix Figure 1 , 9 The rainwater harvesting system 1, rainwater storage system 2, and irrigation system 3 of this utility model, based on the rainwater storage unit 4, realize the storage of rainwater under the solid waste recycling green space and use it for irrigation. In the actual situation of urban blue-green space 5, especially in the design of park green space, taking solid waste recycling land as an example, it is generally arranged in three types: raised land, flat land, and depression land. The raised land and depression land are slopes and adopt the same treatment method.
[0046] In the urban blue-green space 5, a rainwater harvesting system 1, a rainwater storage system 2, and a plant irrigation system 3 are formed on the solid waste recycled green space. The rainwater harvesting system 1 uses existing drainage pipes and ditches, along with collection boxes and other equipment, to collect rainwater, which is then stored via pipelines connected to the rainwater storage system 2. The plant irrigation system 3 uses a water pump to draw water from the rainwater storage system 2 to irrigate the vegetation 6 in the urban blue-green space 5. Both the rainwater harvesting system 1 and the plant irrigation system 3 can be modified from existing equipment and are not the core focus of this patent.
[0047] See appendix Figure 2 , 5-8. The rainwater storage system 2 consists of rainwater storage units 4. The rainwater storage unit 4 includes a planar frame 9 assembled from square tubes 7 and fittings 8. The square tubes 7 on the planar frame 9 are internally interconnected, forming a closed channel. At least two connection ports 10 are formed on each square tube 7. The connection ports 10 are used to connect to a rainwater collection port, an irrigation output port, and to another adjacent planar frame 9. The fittings 8 include straight sections 11, elbows 12, and tees 13. The connection ports 10 are vertical tees located at the ends of the square tubes 7. The planar frame 9 consists of multiple horizontally parallel square tubes 7, connected at both ends by elbows 12 and tees 13. The connection ports 10 are located at fixed positions on the square tubes 7. The square tubes 7 have a multi-cavity structure, which, through horizontal and / or vertical partitions, forms cross-sections with two, three, or four holes.
[0048] The planar frame 9 can be set into other shapes, such as H-shaped or U-shaped, in addition to rectangles. Different shapes can be set according to the terrain of different solid waste recycling sites to maximize rainwater capacity.
[0049] The frame square tubes 7 and fittings 8 here are primarily made of high-molecular plastic, an opaque material to prevent algae growth inside the tubes from affecting water storage. Furthermore, the high-molecular material is lightweight, corrosion-resistant, elastic, tough, and possesses a certain strength, allowing it to be used in the soil for decades. Additionally, they can be connected via hot-melt welding; during on-site assembly, a hot-melt machine enables rapid assembly into different shapes, lengths, and widths to match various terrains in the solid waste recycling site.
[0050] See appendix Figure 3 For flat ground, the planar frames 9 are stacked vertically to form a multi-layer structure 14. Adjacent planar frames 9 are connected by a connection port 10, which is also used to connect rainwater collection port and irrigation output port.
[0051] See appendix Figure 4 For sloping land, the planar frames 9 are stacked in an alternating manner to form a stepped structure 15. Adjacent planar frames 9 are connected by connection ports 10. Similarly, for the stepped structure, some connection ports 10 are also used to connect rainwater collection ports and irrigation output ports.
[0052] The connection port 10 can be implemented using a vertical tee 13, which can be set in the middle of the square tube 7, forming upper and lower interfaces, respectively, for connecting to the rainwater harvesting system 1 and the plant irrigation system 3. It can be implemented by connecting two vertical tees 13 with a section of square tube 7 in the middle.
[0053] Rainwater harvesting system 1 and rainwater storage system 2 form a rainwater collection and storage system. For flat terrain, rainwater storage system 2 is fixed with supports and buried relatively deep underground. The connection port 10 on the top of the planar frame 9 connects to the rainwater collection port. For sloping terrain, rainwater storage system 2 is fixed with supports and buried relatively shallow underground. The connection port 10 on the top of the stepped structure connects to the rainwater collection port, and the slope of the stepped structure matches the slope of the terrain.
[0054] The rainwater harvesting system 1 includes multiple collection ports, a filtration structure, and a sedimentation structure. Each collection port is equipped with a filtration structure, which is connected to the sedimentation structure. The sedimentation structure is connected to the connection port 10 of the rainwater storage system 2. Both the filtration structure and the sedimentation structure are existing technologies, such as sedimentation tanks.
[0055] The plant irrigation system 3 includes a delivery pipe, a water pump, and sprinkler heads. The delivery pipe is connected to the lower connection port 10 of the rainwater storage system 2. The water pump is mounted on the delivery pipe, which is connected to multiple sprinkler heads via multiple branch pipes. The sprinkler heads are arrayed at the bottom or top of the garden vegetation 6, with them positioned at the base for trees and at the top for shrubs and grasses. The water pump and sprinkler control can be achieved using existing electrical control equipment.
[0056] When there is insufficient rainfall during a prolonged drought, natural water can be drawn from rivers and lakes into the pipeline storage system 3, and then irrigated according to the growth needs of vegetation 6 and seedlings in the blue-green space. This is achieved through the arrangement of sprinkler arrays to achieve efficient irrigation.
[0057] See appendix Figure 9 , 10 The rainwater harvesting system collects rainwater from roads and green spaces. The rainwater flows through ditches and the root systems of vegetation to the collection devices, where it is filtered and cleaned by a sedimentation system before flowing into the rainwater storage system. The rainwater in the storage unit also contains dissolved nutrients from the planting soil. During dry periods, the stored rainwater is used to irrigate the vegetation through a plant irrigation system.
[0058] Within the urban blue-green space 5, after the integration of the above systems, an urban ecological garden is formed. The specific construction process is as follows:
[0059] The first step is to determine the structure for installing the rainwater storage system 1 on the solid waste recycling site, based on the different terrain.
[0060] The second step is to assemble the rainwater storage unit 4 and connect the rainwater storage units 4 to form the rainwater storage system 2.
[0061] The third step is to fill the solid waste recycling land where the rainwater storage system 1 is installed with planting soil, so that the connection port 10 of the rainwater storage system 2 is exposed, and plant vegetation 6 on the planting soil, including low shrubs, vegetation and trees.
[0062] The fourth step is to connect the connection port 10 of the rainwater storage system 2 to the rainwater collection port of the rainwater collection system 1. The connection port 10 is the upper connection port 10 of the rainwater storage system 2.
[0063] Fifth step, connect the delivery pipe of the plant irrigation system 3 to the connection port 10 of the rainwater storage system 2. The connection port 10 is the lower connection port 10 of the rainwater storage system 2.
[0064] The sixth step is to connect the connection port 10 of the rainwater storage system 2 to the nearby water system through a pipeline, and adjust the water volume in the rainwater storage system 2 in real time after connecting the water pump.
[0065] This utility model's rainwater harvesting, storage, and irrigation system 3 collects rainwater during periods of abundant rainfall for use in urban landscaping, reducing the erosion and damage of rainwater to regenerated green spaces, while simultaneously irrigating the landscaping. This achieves rainwater recycling in sponge city initiatives.
[0066] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
