Description

Technical Field

[0001] This utility model relates to the field of greening engineering technology, and more specifically, to an oxygenation and water retention device for tree planting. Background Technology

[0002] Tree planting in greening projects refers to the process of transplanting trees to specific areas through scientific planning and manual operation to achieve ecological restoration, landscape creation, or environmental improvement. This process involves multiple stages, including tree species selection, root ball treatment, planting orientation adjustment, and post-planting maintenance. Its core objective is to ensure that trees successfully take root and sprout in their new environment and restore their growth functions. With the acceleration of urbanization and the increasing demand for ecological protection, tree planting is increasingly widely used in urban greening and barren mountain management. However, the problem of soil environmental degradation during the planting process is gradually becoming a key factor restricting tree survival rates.

[0003] Soil tillage is a necessary step in tree planting. Traditional tillage methods (such as mechanical excavation and deep manual tillage) damage the original soil structure, altering the distribution of pores between soil particles. On one hand, tillage compacts the soil, reducing porosity, weakening capillary action, decreasing water infiltration and storage capacity, and significantly reducing water retention. On the other hand, the disruption of soil structure reduces air circulation channels, worsens aeration, and makes it difficult for roots to obtain sufficient oxygen for respiration, directly affecting root development and nutrient absorption in newly planted trees.

[0004] In existing technologies, the reduction in soil water retention and aeration after excavation is typically addressed by adding organic substrates (such as humus and peat). However, such methods suffer from drawbacks such as high cost, complex construction, and insufficient sustainability of effects. For example, organic substrates require regular replenishment, and long-term use increases the cost of greening maintenance. Therefore, there is an urgent need to develop a technical solution that can simultaneously improve soil structure and enhance water retention and aeration during tree planting, thereby increasing the survival rate of newly planted trees and reducing the overall cost of greening projects. Utility Model Content

[0005] The purpose of this invention is to provide an oxygenation and water retention device for tree planting, aiming to solve the technical problems mentioned in the background art.

[0006] The embodiments of this utility model are implemented as follows:

[0007] This application provides an oxygenation and water retention device for tree planting, comprising: an installation tube with openings at both ends and multiple through holes on its circumferential surface; a water-retaining and breathable layer filling the internal space of the installation tube; a filter structure including a first filter layer and a second filter layer, wherein the first filter layer covers the outer circumferential surface of the installation tube, and the second filter layer covers the outer circumferential surface of the first filter layer, and the pore size of the first filter layer is smaller than that of the second filter layer; and an observation structure including a first conductive element, a second conductive element, a power supply, and a light source, wherein one end of each of the first and second conductive elements extends into the water-retaining and breathable layer and extends to a first port inside the installation tube, and the other ends of each of the first and second conductive elements protrude from a second port of the installation tube, and the two are electrically connected through the light source, and the power supply is used to supply power to the light source.

[0008] Furthermore, based on the aforementioned scheme, the first filter layer is a rubber sponge, and the second filter layer is a stainless steel annular filter screen.

[0009] Furthermore, based on the aforementioned scheme, the second filter layer is detachably connected to the mounting tube.

[0010] Furthermore, based on the aforementioned scheme, a first annular component is circumferentially provided at the first end of the outer ring surface of the mounting tube, and a second annular component is circumferentially provided on the second filter layer for docking with the first annular component. The first annular component and the second annular component are connected by bolts.

[0011] The second end of the outer ring surface of the mounting tube is threaded with an annular locking member, and an annular insert is provided on the side of the annular locking member facing the second filter layer for insertion into the gap between the second filter layer and the mounting tube.

[0012] Furthermore, based on the aforementioned scheme, the first port and the second port of the installation pipe are respectively provided with a first protective layer and a second protective layer, both of which have the functions of water permeability and air permeability.

[0013] Furthermore, based on the aforementioned scheme, an annular pressure plate is provided on the side of the second protective layer away from the mounting tube, and the annular pressure plate is connected to the annular locking member.

[0014] Furthermore, based on the aforementioned scheme, the aforementioned light source is an LED light.

[0015] Furthermore, based on the aforementioned scheme, the water-retaining and breathable layer is a mixture of coarse sand and coconut coir.

[0016] Furthermore, based on the aforementioned scheme, the installation pipe is made of PVC material.

[0017] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0018] In practical use, the oxygenation and water retention device of this application involves vertically inserting an installation pipe with open ends into the soil layer (first end facing down, second end facing up, extending to the soil surface, with the light source exposed). The annular perforations inside the pipe, along with the filling water-retaining and breathable layer (such as a mixture of coarse sand and coconut coir), form an air-water transmission channel. Soil moisture passes through a double-layer filtration structure consisting of a second filter layer (with larger pores) and a first filter layer (with smaller pores), preventing large soil particles from intruding while allowing water and air to pass through, thus achieving water retention and aeration. When soil moisture content changes, the resistance of the water-retaining and breathable layer changes accordingly, causing a change in the brightness of the light source (higher water content results in higher current and higher brightness). Soil moisture can be determined by observing the light source's status. Its advantages are: compared to existing technologies that add organic matrix, this solution simultaneously improves soil water retention and aeration through a physical structure (double-layer filtration + perforated installation pipe), eliminating the need for regular material replenishment and reducing maintenance costs; the installation pipe is reusable and easy to install, and the light source provides direct feedback on humidity, preventing over-irrigation.

Detailed Implementation

[0030] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example 1

[0031] Please refer to Figures 1-4 This application provides an oxygenation and water retention device for tree planting, comprising: an installation tube 2 with openings at both ends and multiple through holes 5 on its circumferential surface; a water-retaining and breathable layer 9 filling the internal space of the installation tube 2; a filtration structure including a first filter layer 1 and a second filter layer 4, wherein the first filter layer 1 covers the outer circumferential surface of the installation tube 2, and the second filter layer 4 covers the outer circumferential surface of the first filter layer 1, and the pore size of the first filter layer 1 is smaller than that of the second filter layer 4; and an observation structure including a first conductive element 7, a second conductive element 8, a power supply 12, and a light source 11, wherein one end of the first conductive element 7 and the second conductive element 8 extends into the water-retaining and breathable layer 9 and extends to a first port inside the installation tube 2, and the other end of the first conductive element 7 and the second conductive element 8 protrudes from the second port of the installation tube 2, and the two are electrically connected through the light source 11, and the power supply 12 supplies power to the light source 11.

[0032] In practical use, the oxygenation and water retention device of this application involves vertically inserting the installation pipe 2, open at both ends, into the soil layer (first end facing down, second end facing up, extending to the soil surface, with the light lamp 11 exposed). The annular through-hole 5 inside the pipe and the filled water-retaining and breathable layer 9 (such as a mixture of coarse sand and coconut coir) form an air-water transmission channel. Soil moisture passes through the double-layer filtration structure of the second filter layer 4 (with larger pores) and the first filter layer 1 (with smaller pores), blocking the intrusion of large soil particles while allowing water and air to pass through, thus achieving water retention and breathability. When the soil moisture content changes, the resistance of the water-retaining and breathable layer 9 changes accordingly, causing the brightness of the light lamp 11 to change (the higher the moisture content, the greater the current and the higher the brightness). The soil moisture can be judged by observing the state of the light lamp 11. Its advantages are: compared with the existing technology of adding organic matrix, this solution improves the soil's water retention and breathability simultaneously through the physical structure (double-layer filtration + through-hole 5 installation pipe 2), eliminating the need for regular material replenishment and reducing maintenance costs; the installation pipe 2 is reusable and easy to construct, and the light lamp 11 provides direct feedback on humidity to avoid over-irrigation.

[0033] Preferably, in actual use, multiple oxygenation and water retention devices can be used, arranged around the trees. The dimensions of the mounting pipe 2 for any oxygenation and water retention device can be set with reference to the following standards:

[0034] For small trees (root depth <30cm, such as purple calyx spur, wood chrysanthemum, etc.): install pipe 2 with a diameter of 5-10cm and a length of 20-30cm, through hole 5 with a diameter of 1-2mm and a hole spacing of 5-8cm.

[0035] For medium-sized trees (root depth 30-60cm, such as purple-leaf plum): install pipe 2 with a diameter of 15-25cm and a length of 40-60cm, and through hole 5 with a diameter of 3-4mm and a hole spacing of 8-12cm.

[0036] For large trees (root depth > 60cm, such as tall trees, large plants like Ligustrum lucidum, etc.): Install pipe 2 with a diameter of 30-40cm and a length of 1m, and through hole 5 with a diameter of 5-6mm and a hole spacing of 10-15cm. Example 2

[0037] Please refer to Figure 1 , Figures 4-9 This embodiment is the same as embodiment 1 in terms of main body, the main difference being that the first filter layer 1 is a rubber sponge and the second filter layer 4 is a stainless steel annular filter screen.

[0038] In the above embodiments, the use of rubber sponge for the first filter layer 1 and stainless steel annular filter for the second filter layer 4 has the following advantages: the stainless steel annular filter is sturdy and corrosion-resistant, and its small pore size (e.g., 0.8mm) can effectively intercept large soil particles, prevent the through hole 5 of the installation pipe 2 from being blocked, and maintain long-term air and water permeability; the rubber sponge has rich pores and a soft texture, which can further block the intrusion of fine soil particles, reduce the risk of blockage, and improve the adaptability and durability of the device to the soil environment.

[0039] In a preferred embodiment, the second filter layer 4 is detachably connected to the mounting tube 2.

[0040] In the above embodiment, the first filter layer 1 fills the gap between the second filter layer 4 and the mounting pipe 2. When the stainless steel filter screen accumulates soil particles or debris due to long-term use, it can be quickly disassembled to remove the blockage and restore the filtration performance. If the rubber sponge ages, is damaged, or adsorbs too many impurities, it can also be disassembled and replaced simultaneously to ensure that the double-layer filtration structure continues to effectively block soil intrusion and maintain the unobstructed flow of the through hole 5 of the mounting pipe 2. The detachable design improves the convenience of device maintenance, avoids the decline in water retention and air permeability due to filter layer blockage, extends the overall service life of the oxygenation and water retention device, reduces long-term use costs, and adapts to the continuous maintenance needs under different soil conditions in greening projects.

[0041] In a preferred embodiment, a first annular member 15 is circumferentially provided at the first end of the outer ring surface of the mounting tube 2, and a second annular member 16 is circumferentially provided on the second filter layer 4 for docking with the first annular member 15. The first annular member 15 and the second annular member 16 are connected by bolts 17.

[0042] The second end of the outer ring surface of the mounting tube 2 is threaded with an annular locking member 6. The annular locking member 6 is provided with an annular insert 14 on the side facing the second filter layer 4, which is used to insert and cooperate with the gap between the second filter layer 4 and the mounting tube 2.

[0043] In the above embodiments, the bolt 17 connection structure provides reliable fixing strength, ensuring that the second filter layer 4 is not easily detached or displaced in the soil environment. At the same time, it facilitates quick disassembly and maintenance of the filter screen by removing the bolt 17. The threaded design of the annular locking member 6 can adjust the locking force by rotation. With the structure of the annular insert 14 inserted into the gap, it can not only further fix the position of the second filter layer 4, but also compress and fix the first filter layer 1 (rubber sponge) to prevent it from displacing under the insertion and removal of the installation tube 2 or the action of soil stress. This dual fixing structure (bolt 17 butt joint + threaded locking) takes into account the connection stability and disassembly convenience, adapts to the installation accuracy requirements under different construction scenarios, and improves the versatility and interchangeability of device components through the standardized design of annular and locking members, thereby reducing construction and maintenance costs.

[0044] Specifically, the aforementioned annular locking member 6 can be removed from the second port of the mounting tube 2.

[0045] In a preferred embodiment, the first port and the second port of the installation pipe 2 are respectively provided with a first protective layer 3 and a second protective layer 10, both of which have the functions of water permeability and air permeability.

[0046] In the above embodiment, the first protective layer 3 can prevent the soil at the bottom of the installation pipe 2 from rushing into the pipe when it is inserted into the soil, thus avoiding contamination or blockage of the filling water-retaining and breathable layer 9, while allowing water and air to pass through and maintaining the air-water exchange efficiency at the bottom of the pipe; the second protective layer 10 can block surface debris (such as fallen leaves and gravel) from entering the upper opening of the installation pipe 2, preventing the accumulation of external impurities, while keeping the pipe opening breathable and permeable, ensuring that the surface soil moisture can participate in the circulation normally through the second port; the two protective layers provide physical protection for both ends of the installation pipe 2 without affecting the core function of the device, reducing the interference of soil particles and external debris on the internal structure of the pipe, extending the service life of the device, and improving its applicability and stability in complex outdoor environments.

[0047] Optionally, both the first protective layer 3 and the second protective layer 10 are polypropylene needle-punched felt. The first protective layer 3 is synchronously fixed by bolts 17 connecting the first annular member 15 and the second annular member 16.

[0048] In a preferred embodiment, an annular pressure plate 13 is provided on the side of the second protective layer 10 away from the mounting tube 2, and the annular pressure plate 13 is connected to the annular locking member 6.

[0049] In the above embodiment, the annular pressure plate 13, through its connection with the annular locking member 6, can exert a uniform clamping force on the second protective layer 10, ensuring its secure fit against the second port of the installation tube 2 and preventing displacement or detachment of the protective layer due to soil settlement or external impact. Furthermore, the connection between the annular pressure plate 13 and the annular locking member 6 allows for simultaneous positioning and fixing of the second protective layer 10, improving operational convenience. Example 3

[0050] Please refer to Figures 1-4 This embodiment is the same as the embodiment 1 in terms of main body, the main difference being that the above-mentioned light lamp 11 is an LED lamp.

[0051] In the above embodiments, the light lamp 11 is an LED lamp, which has the advantages of low power consumption, high brightness, long life, small size and strong environmental adaptability.

[0052] As a preferred embodiment, the water-retaining and breathable layer 9 is a mixture of coarse sand and coconut coir.

[0053] In the above embodiments, coarse sand has high porosity, which can significantly improve the permeability of the soil root zone and promote tree root respiration; coconut coir has high water retention and is rich in organic matter, which can stably retain soil moisture and provide some nutrients; the mixing ratio of the two can be flexibly adjusted according to tree species and soil characteristics (such as a higher proportion of coarse sand for drought-resistant tree species and a higher proportion of coconut coir for moisture-loving tree species), taking into account the different tree needs for permeability and water retention, and the materials are low in cost and widely available. The structure formed after mixing is not easy to compact and can maintain the air and water exchange function for a long time, effectively improving the soil microenvironment and increasing the survival rate of trees.

[0054] As a preferred implementation method, the installation pipe 2 is made of PVC material.

[0055] In the above embodiments, the use of PVC material for the installation pipe 2 has the following advantages: PVC material has high compressive strength (40-50MPa) and high tensile strength (40-60MPa), which can withstand soil compression and pressure during construction insertion, and is not easily deformed or broken; it has low density (1.35-1.45g / cm³), is lightweight, easy to handle and install, and reduces labor costs; it has stable chemical properties, is resistant to acid and alkali corrosion and soil microbial erosion, and is suitable for long-term burial in various soil environments; its Vicat softening temperature is ≥80℃, and it has good heat resistance, which can adapt to temperature changes in different seasons; in addition, PVC material is inexpensive, easy to process, and can be flexibly cut into different pipe diameters and lengths according to the needs of tree species, and waste pipes can be recycled and reused, which meets environmental protection requirements.
