Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, specifically a porous water collection and infiltration pipeline for parks and green spaces. Background Technology

[0002] With the acceleration of urbanization, parks and green spaces, as an important component of urban ecosystems, not only beautify the environment, improve the microclimate, and conserve water resources, but also play a role in regulating urban stormwater, replenishing groundwater, and improving ecological permeability. However, existing park and green space drainage and infiltration systems generally suffer from problems such as simple structure, low drainage efficiency, and separation of water collection and infiltration functions. Traditional green space drainage designs often use single-layer gravel cushion layers or drainage pipe structures. These structures are prone to poor drainage and severe surface water accumulation during heavy rainfall. Furthermore, due to short infiltration paths and insufficient filtration layers, rainwater purification capacity is weak, and there is even a risk of groundwater pollution. In addition, some green space infiltration systems are prone to losing their permeability due to silt blockage during long-term use, making maintenance difficult and shortening their service life. These systems fail to meet the needs of ecological parks for integrated drainage systems that combine water collection, purification, and re-infiltration. Therefore, this paper proposes a porous water collection and infiltration pipeline for parks and green spaces to address these issues. Utility Model Content

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A porous water collection and infiltration pipe for park green spaces includes a base layer 1 and planting soil layers 2 on both sides of the base layer 1. Gravel layers 3 are laid on the top and sides of the base layer 1, serving as support and primary filtration to effectively enhance rainwater infiltration stability. Multiple stone slabs 4 are evenly distributed on the top of the gravel layer 3, with a certain gap between them. Sand layers 5 are laid above the gravel layer 3 on both sides, further filtering fine sediment and providing a stable water flow transition layer. The planting soil layers 2 are placed on top of the sand layers 5 for planting and water retention.

[0025] In the internal areas of the gravel layer 3, sand layer 5, and planting soil layer 2, infiltration pipe networks 6 are installed. The infiltration pipe networks 6 adopt a mesh distribution form, which can realize multi-directional infiltration and recycling of rainwater. A filter 7 is installed at the top center of the infiltration pipe network 6 to initially remove suspended solids and impurities in the water flow; regulating devices 8 are installed on both sides of the top of the infiltration pipe network 6 to control the infiltration rate and soil moisture.

[0026] Further, as shown in the figure, the infiltration pipe network 6 includes multiple horizontal pipes 61, which are laid parallel to each other on the upper side of the base layer 1, forming the main water flow channel. Each horizontal pipe 61 is vertically connected to a drain pipe 62 in the middle and on both sides, for introducing upper-layer infiltrated water into the lower-layer pipe system. A main water collection pipe 63 is installed below the drain pipes 62 on both sides to collect rainwater collected by the drain pipes 62. Multiple branch water collection pipes 64 are connected to one side of the main water collection pipe 63, and these branch pipes 64 are further distributed in the edge area of ​​the green space to expand the collection range. A regulating pipe 65 is installed on the upper side of each branch water collection pipe 64 to regulate the water flow rate and infiltration rate.

[0027] In this structure, a filter 7 is installed at the top of the drain pipe 62, and the filter 7 is located on the outside of the stone slab 4, so that the water flowing into the drain pipe first undergoes multi-stage filtration to prevent impurities from clogging the pipe. An adjustment device 8 is installed at the top of the regulating pipe 65, and the adjustment device 8 is located inside the planting soil layer 2, which can directly sense changes in soil moisture and make adaptive adjustments.

[0028] Furthermore, the water collection branch pipe 64 on one side is connected to the inlet pipe via a water pump. A one-way valve structure is installed at the connection between the water collection branch pipe 64 and the water pump to ensure that rainwater flows into the pipe network system in only one direction, preventing contamination of the water pump. Through this water pump, rainwater can be pumped back and reused, and the collected water can be transported back to the green space sprinkler irrigation or landscape water system, realizing the resource recycling of rainwater.

[0029] As shown in the figure, the filter 7 includes a housing 71. From top to bottom, the inner cavity of the housing 71 is fitted with a first filter layer 72, a second filter layer 73, and a third filter layer 74. The first filter layer 72 is a coarse sand layer used to remove larger particulate impurities; the second filter layer 73 is an activated carbon layer or a porous ceramic granule layer used to adsorb organic pollutants; the third filter layer 74 is a composite layer of fine sand and cotton, used to further purify rainwater. A support frame 75 is installed at the bottom of the third filter layer 74. The support frame 75 is spirally installed inside the housing 71, supporting the filter material and allowing for disassembly and maintenance through rotation. A handle 76 is provided at the bottom of the support frame 75 for easy manual removal and cleaning.

[0030] The top of the housing 71 is provided with an outer groove 77, and a pull ring 78 is rotatably connected to the inner side of the outer groove 77. The pull ring can be used to assist in disassembling the filter. The top of the housing 71 is also provided with an inner groove 79, and water permeable holes are opened in the center of the inner side of the housing and at the bottom of the inner groove to keep the water flowing smoothly.

[0031] The regulating device 8 includes a sealing ring 81 and a water-absorbing strip 82. The sealing ring 81 is installed at the top of the regulating pipe 65 to ensure the sealing of the connection. The water-absorbing strip 82 is located inside the sealing ring 81 and can actively absorb seepage water and transport the water to the surface of the planting soil. The top of the water-absorbing strip 82 is forked into multiple branches, which can expand the seepage coverage area, thereby keeping the plant roots moist and promoting growth.

[0032] During operation, when it rains, the water in the middle first flows through the gaps in the stone slabs 4 into the gravel layer 3, where it is coarsely filtered to remove particulate impurities. The water on both sides then flows through the sand layer 5 to filter the soil in the planting soil layer 2, preventing soil loss. The rainwater then flows along the infiltration pipe network 6 into the drain pipe 62, and is collected by the main collection pipe 63 and the branch collection pipes 64. When the rainfall is heavy, the water flows through the filter 7, where it is purified through multiple filtration layers, reducing pipe network blockage. When the groundwater level drops or the vegetation's water demand increases, the water pump can be activated to pump the collected rainwater back, achieving water resource recycling.

[0033] The regulating device 8 includes a sealing ring 81 and a water-absorbing strip 82. The sealing ring 81 is installed at the top of the regulating pipe 65, and the water-absorbing strip 82 is installed on the inner side of the sealing ring 81. Multiple branches are connected to the top of the water-absorbing strip 82.
