DETAILED DESCRIPTION

[0022] The following describes in detail the specific implementation methods of the rainwater utilization pipe network system for solid waste regeneration green space, rainwater collection, storage and irrigation system and construction method of the present invention in conjunction with the accompanying drawings.

[0023] See attached Figure 1 、 9 The present invention's rainwater collection system 1, rainwater storage system 2, and irrigation system 3, based on rainwater storage units 4, store rainwater beneath the solid waste recycling green space for irrigation. In the actual design of urban blue-green spaces 5, especially park green spaces, solid waste recycling land is typically arranged in three types: convex, flat, and concave. Both convex and concave land are sloped and are treated in the same manner.

[0024] Within the urban blue-green space 5, a rainwater collection system 1, a rainwater storage system 2, and a plant irrigation system 3 are established on the solid waste regeneration green land. The rainwater collection system 1 utilizes existing drainage pipes and ditches, combined with equipment such as collection boxes, to collect rainwater. The rainwater is then connected to the rainwater storage system 2 via pipes for storage. The plant irrigation system 3 uses a pump to draw water from the rainwater storage system 2 to irrigate the vegetation 6 within the urban blue-green space 5. Both the rainwater collection system 1 and the plant irrigation system 3 can be modified from existing equipment and are not essential to this patent.

[0025] See attached Figure 2 、 5 -8. The rainwater storage system 2 consists of a rainwater storage unit 4. The rainwater storage unit 4 comprises a planar frame 9 assembled from square tubes 7 and fittings 8. The square tubes 7 on the planar frame 9 are interconnected, forming a closed channel. The square tubes 7 are formed with at least two connection ports 10, which are used to connect to a rainwater collection port, an irrigation output port, and another adjacent planar frame 9. The fittings 8 include a straight connection 11, an elbow 12, and a tee 13. The connection port 10 is a vertical tee located at the end of the square tube 7. The planar frame 9 comprises multiple horizontally parallel square tubes 7, connected at both ends by elbows 12 and tees 13. The connection port 10 is located at a fixed position on the square tube 7. The square tubes 7 have a multi-cavity structure, with cross-sections formed into two-, three-, or four-hole shapes through transverse and / or longitudinal partitioning.

[0026] The plane frame 9 can be configured into other shapes, such as H-shape or U-shape, in addition to rectangle. It can be configured into different shapes according to the terrain of different solid waste recycling sites to accommodate a larger rainwater capacity.

[0027] The frame square tubes 7 and fittings 8 are primarily made of polymer plastic, an opaque material to prevent algae from forming inside the tubes and affecting water storage. Furthermore, polymer materials are lightweight, corrosion-resistant, elastic, and possess a certain strength, allowing them to last for decades in the soil. Furthermore, they can be connected by hot melt. During on-site assembly, hot melt machines can be used to quickly assemble them into various shapes, lengths, and widths to suit the various terrains of the solid waste recycling site.

[0028] See attached Figure 3 For flat land, the plane frames 9 are stacked vertically to form a multi-layer structure 14. The adjacent plane frames 9 are connected through the connection port 10, and the connection port 10 is also used to connect the rainwater collection port and the irrigation output port.

[0029] See attached Figure 4 For slopes, the plane frames 9 are staggered and stacked to form a stepped structure 15, and adjacent plane frames 9 are connected through connecting ports 10. Similarly, for the stepped structure, some connecting ports 10 are also used to connect rainwater collection ports and irrigation output ports.

[0030] The connection port 10 can be realized by a vertical phase tee 13, which can be set in the middle position of the square tube 7, forming upper and lower interfaces upward and downward, respectively used to connect with the rainwater collection system 1 and the plant irrigation system 3. It can be realized by two vertical phase tees 13 with a square tube 7 connected in the middle.

[0031] The rainwater collection system 1 and the rainwater storage system 2 form a rainwater collection and storage system. For flat land, the rainwater storage system 2 is fixed with supports and then buried beneath the flat land. It can be buried relatively deep, and the connection port 10 above the planar frame 9 is connected to the rainwater collection port. For sloping land, the rainwater storage system 2 is fixed with supports and then buried beneath the flat land. It can be buried relatively shallowly, and the connection port 10 above the stepped frame is connected to the rainwater collection port. The slope formed by the stepped frame matches the slope of the slope.

[0032] The rainwater collection system 1 includes multiple collection ports, a filtration structure, and a water sedimentation structure. Each collection port is provided with a filtration structure, which is connected to the water sedimentation structure, which is connected to the connection port 10 of the rainwater storage system 2. The filtration structure and water sedimentation structure are both products of the prior art, such as sedimentation tanks and other equipment.

[0033] 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 water supply branches. The sprinkler heads are arranged in an array at the bottom or top of the garden vegetation 6, located at the roots of trees and at the top of shrubs and grasses. The water pump and sprinkler control systems can both use existing electronic control devices.

[0034] When there is a long-term lack of rainfall during a drought period, 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 the sprinkler array to achieve efficient irrigation.

[0035] See attached Figure 9 、 10 The rainwater collection system collects rainwater from roads and green spaces. The rainwater flows through ditches and the root gaps of vegetation to a collection device. The device then connects to a water sedimentation structure through a filtration structure, where it is filtered and cleaned before flowing into a rainwater storage system. The rainwater in the rainwater storage unit also contains dissolved nutrients from the soil that has flowed through it. During droughts, the stored rainwater is used to irrigate the vegetation through a plant irrigation system.

[0036] In the Urban Blue-Green Space 5, after the above systems are integrated, an urban ecological garden is formed. The specific construction process is as follows: The first step is to determine the structure of the rainwater storage system 1 to be installed on the solid waste recycling land according to the different terrain.

[0037] In the second step, the rainwater storage units 4 are assembled and connected to form the rainwater storage system 2 .

[0038] 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.

[0039] 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 , where the connection port 10 is the connection port 10 on the upper layer of the rainwater storage system 2 .

[0040] The fifth step is to connect the connection port 10 of the rainwater storage system 2 to the delivery pipe of the plant irrigation system 3 , where the connection port 10 is the connection port 10 of the lower layer of the rainwater storage system 2 .

[0041] 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 the connection through a water pump.

[0042] The rainwater collection, storage and irrigation system 3 of the present invention collects rainwater during periods of abundant rainfall and uses it to replenish urban gardens, reducing the erosion and damage of rainwater to solid waste recycling green spaces while also irrigating the gardens, thus achieving rainwater recycling in sponge cities.

[0043] The above are only preferred embodiments of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
