[0028] Application Overview:

[0029] With the continuous acceleration of urbanization, street trees have become an indispensable part of urban construction. While street trees play a variety of beneficial roles such as ecology and landscape, their own water demand is also huge, which has brought pressure to the city's water supply. Urban street trees are generally planted at intervals, and the conventional watering method is extensive sprinkler irrigation or flooding. Although this watering method saves time and labor, it will cause a lot of water resources to be wasted, soil compaction, and the normal growth of street trees will be affected due to excessive water.

[0030] Garden waste refers to various plant residues and waste generated in the process of urban landscaping, which has the characteristics of high transportation cost, complex composition, and easy decay. With the continuous acceleration of urbanization, more and more garden waste is generated, and the environmental problems it brings are becoming increasingly prominent. Therefore, seeking methods for harmless treatment and resource utilization of garden waste is of great significance to saving natural resources, preventing environmental pollution, and achieving healthy development of ecological economy.

[0031] Garden waste, especially garden waste such as tree branches, is crushed, sieved, air-dried, and added with a certain proportion of water-based polyurethane adhesive. It is then placed in a mold, compacted, dried and formed to obtain an ecological covering mat of the desired shape. It can be used to cover the exposed soil around street trees, which can not only reduce evaporation and maintain soil moisture, but also effectively store rainwater, thereby improving the water utilization efficiency of landscaping. It also provides a new way for the resource utilization of garden waste.

[0032] Figure 1 The figure shows a schematic structural diagram of a roadside tree water-saving drip irrigation device based on a garden waste ecological covering mat provided by an embodiment of the utility model; Figure 2 Shown Figure 1 A magnified view of middle; Figure 3 Shown Figure 1 The enlarged view of B in the figure; Figure 1 As shown, combined Figure 2 as well as Figure 3, a street tree water-saving drip irrigation device based on a garden waste ecological covering mat, the water-saving irrigation device comprises: a water source 1; a drip irrigation component 2, one end of the drip irrigation component 2 extends to the water source 1, and the other end of the drip irrigation component 2 is laid on both sides of the street tree, the drip irrigation component 2 comprises a plurality of drippers 25, and the plurality of drippers 25 are arranged in the surrounding area of ​​the street tree; an ecological covering mat 3, the ecological covering mat 3 is laid in the tree hole of the street tree, and the ecological covering mat 3 covers the dripper 25, and the ecological covering mat 3 is used to cover the exposed soil and the dripper 25 in the surrounding area of ​​the street tree, wherein the drip irrigation component 2 and the ecological covering mat 3 are arranged on the soil layer 4. Compared with the traditional sprinkler irrigation or flooding irrigation method, the drip irrigation device not only saves water resources, but also ensures the normal growth state of the street tree. Placing the ecological covering mat 3 in the tree hole of the street tree can reduce the evaporation of soil moisture in the surrounding area of ​​the street tree and the loss of surface runoff, improve the soil moisture retention capacity, help reduce the consumption of water resources, and also avoid the occurrence of soil compaction.

[0033] Specifically, one end of the irrigation component 2 is extended to the water source 1, and the other end of the irrigation component 2 is laid along the root system of the street tree, and then the ecological covering mat 3 is placed in the tree hole of the street tree. At the same time, the ecological covering mat 3 can also cover the dripper 25. The ecological covering mat 3 is placed above the dripper 25 to play a protective role, which can reduce the aging of the drip irrigation component 2 to a certain extent and extend the service life of the drip irrigation component 2. The drip irrigation component 2 and the ecological covering mat 3 are arranged on the soil layer 4 to facilitate the work of construction personnel.

[0034] It should be understood that the water source 1 can be a water well or a municipal water well arranged below the soil layer 4, or a movable water source arranged above the soil layer 4, as long as it can provide water for the drip irrigation device.

[0035] In a possible implementation, the drip irrigation assembly 2 includes: a drip irrigation pipe 21; a filter 22, which is installed on a side of the drip irrigation pipe 21 close to the water source 1, and the filter 22 is used to pre-treat the water entering the drip irrigation pipe 21; and a valve 23, which is installed on a side of the drip irrigation pipe 21 away from the water source 1.

[0036] Specifically, in order to prevent the drip port 24 from being blocked, a filter 22 is installed at the front end of the drip irrigation pipe 21 connected to the water outlet well. The filter 22 can pre-treat the water entering the drip irrigation pipe 21, and filter out branches, leaves, stones or other floating objects that are easy to block the drip port 2 through the filter 22, so that the water entering the drip irrigation pipe 21 is free of other impurities and can smoothly drip out through the drip port 24. The valve 23 is used to control the flow rate of the water. The water filtered by the filter 22 controls the flow rate of the water through the valve 23. The valve 23 can be adjusted according to the actual water demand requirements of the street trees to control the water supply speed.

[0037] When the drip irrigation pipe 21 is laid and transported, it should be noted that the drip irrigation pipe 21 should not be worn. The drip irrigation pipe 21 should not be laid too tight, leaving a certain amount of slack for free expansion and contraction, but it should not be too loose to cause unnecessary waste.

[0038] Figure 5 FIG. 1 is a schematic diagram of the connection structure between the dripper and the drip irrigation pipe of a water-saving drip irrigation device provided by an embodiment of the utility model. Figure 5 As shown, combined Figure 1 The drip irrigation assembly 2 also includes: a plurality of drip ports 24 , which are arranged on the drip irrigation pipe 21 in the surrounding area of ​​the root system of each roadside tree; and a plurality of drippers 25 which are installed in the plurality of drip ports 24 in a one-to-one correspondence.

[0039] Specifically, the existing irrigation method does not take into account the design of the interval planting of street trees. Generally, drip outlets 24 are set at equal intervals on the drip irrigation pipe 21, resulting in a large amount of water not being irrigated near the root system of the street trees, while the area near the root system is an area with a large water demand, thereby causing a waste of water resources. By opening a drip outlet 24 on the drip irrigation pipe 21 near the root system of each street tree, water can be accurately distributed to the root area of ​​the street tree that needs water, thereby improving water utilization efficiency and saving water.

[0040] After the drip irrigation pipe 21 is laid, a hole is opened on the drip irrigation pipe 21 to form a dripping port 24. The multiple dripping ports 24 correspond to the multiple drip irrigation heads 25. The drippers 25 can be installed in the dripping pipe 24 one by one. The drippers 25 and the dripping ports 24 can be connected by threads.

[0041] Optionally, the material of the drip irrigation pipe 21 can be PVC or PE. Most of the drip irrigation pipes 21 made of PE are black, which can prevent ultraviolet absorption and slow down aging. The drip irrigation pipe 21 made of PVC has the advantages of non-flammability and high strength. The dripper 25 can be a pressure-compensating dripper or a micro-sprinkler, as long as it can achieve drip irrigation.

[0042] In a possible implementation, a plurality of drip ports 24 are provided on the side of the drip irrigation pipe 21 in the area surrounding the root system of each street tree. In order to prevent the drip holes 26 from being blocked by soil, the drip ports 24 are provided on the side of the drip irrigation pipe 21 .

[0043] In a possible implementation, the number of dripping holes 24 on the drip irrigation pipe 21 near the root system of each roadside tree is 3-5, and the interval between each dripping hole 24 is 15-20 cm.

[0044] It should be understood that in this implementation, the number of dripping ports 24 on the drip irrigation pipe 21 near the root system of each street tree can be specifically determined according to the size and water demand of the street tree, and the spacing between each dripping port 24 can also be specifically determined according to the size and water demand of the street tree. Therefore, the dripping ports 24 on the drip irrigation pipe 21 can be specifically opened according to the spacing of the street trees, which is simple to operate and has high flexibility.

[0045] In a possible implementation, a drip hole 26 is provided on the dripper 25, and the direction of the drip hole 26 is the same as the direction of the drip port 24. When the water source 1 reaches the end of the drip irrigation pipe 21 through the drip irrigation pipe 21, the water in the drip irrigation pipe 21 will form a certain water pressure, so that when the water reaches the drip hole 26, under the action of the water pressure, the water drips into the soil along the drip hole 26.

[0046] It should be understood that since the drip ports 24 are all opened on the side of the drip irrigation pipe 21 in the surrounding area of ​​the root system of each street tree, the drip port 24 is threadedly connected to the drip head 25. In order to prevent the drip hole 26 from being blocked by soil, a drip hole 26 is opened on the side of the drip head 25. If the drip port 24 is opened above the drip irrigation pipe 21, soil is formed when water contacts the soil on the ground, and the soil splashes to the drip port 24 and easily blocks the drip port 24. If the drip port 24 is opened below the drip irrigation pipe 21, the drip port 24 is easily combined with the soil below to block the drip port 24. Therefore, in this implementation, by opening the drip port 24 on the side of the drip irrigation pipe 21, connecting the drip head 25 to the drip port 24, and the drip hole 26 is also set on the side of the drip head 25, it can well prevent the soil from blocking the drip hole 26, thereby further improving the drip irrigation efficiency.

[0047] It should also be understood that in the present application, the number of the drip hole 26 is one. Since the opening direction of the drip hole 26 is the same as the direction of the drip port 24, opening a drip hole 26 on the dripper 25 can greatly save water consumption during the irrigation process. The water dripping from the drip hole 26 can also be accurately irrigated to the surrounding areas of the street trees that need water, avoiding waste of water resources.

[0048] Figure 4 The figure is a schematic diagram of the structure of the ecological covering pad of the water-saving drip irrigation device provided by one embodiment of the utility model; Figure 4 As shown, the shape of the ecological covering mat 3 is ring-shaped, and the thickness of the ecological covering mat 3 is 3-5 cm.

[0049] Specifically, when laying the ecological covering mat 3, since the shape of the ecological covering mat 3 is annular, it is convenient to use. When using it, cut an incision in the ecological covering mat 3, and the ecological covering mat 3 can be easily laid in the tree hole of the street tree. Since the ecological covering mat 3 is laid in the tree hole of the street tree, it plays a role in preventing the evaporation of water in the area near the root system of the street tree and protecting the drip irrigation pipe 21, and the dripper 25 is also placed under the ecological covering mat 3. When drip irrigation is performed, the ecological covering mat 3 further reduces the evaporation of water, and the water dripping from the dripper 25 directly enters the vicinity of the root system of the street tree, which greatly improves the utilization efficiency of water. The thickness of the ecological covering mat 3 is 5 cm. If the ecological covering mat 3 is too thick, the permeability of the soil will deteriorate. If the ecological covering mat 3 is too thin, it will not reduce the evaporation of water.

[0050] In a possible implementation, the ecological covering mat 3 is made by adding an adhesive to crushed garden waste and putting the crushed garden waste into a mold and compacting it into a ring shape.

[0051] Specifically, the preparation process of the ecological mulch mat of garden waste is as follows: weigh a certain weight of garden waste such as tree branches, crush it, and then pass it through a 0-1cm iron sieve to obtain a raw material with a particle size of about 0-1cm, place it in a dry and ventilated place to air-dry, and set aside. Then add a water-based polyurethane adhesive accounting for 30% of the weight of the garden waste, mix it evenly, and put it into a ring-shaped plastic mold that meets the size of the tree hole, compact it with a heavy object, and place it in a dry and ventilated place to dry naturally for 48 hours, so that it can be air-dried and bonded into shape, and then take it out of the mold to obtain a garden waste ecological mulch mat with a thickness of about 5cm. Compared with using garden waste directly as a mulch, preparing garden waste into an ecological mulch mat is not easy to blow away and drift to the road surface, reducing the impact of dust pollution on the city's appearance;

[0052] Garden waste refers to various plant residues and waste generated in the process of urban gardening and greening. Garden waste includes tree branches, which have the characteristics of high transportation cost, complex composition, and easy decay. With the continuous acceleration of urbanization, more and more garden waste is generated, and the environmental problems it brings are becoming increasingly prominent. The ecological covering mat 3 prepared with garden waste as raw materials is laid in the tree hole of the street tree to cover the exposed soil around the street tree, which can reduce the evaporation of water around the street tree. Water evaporation will affect soil moisture and air permeability, and then affect the growth of street trees. Laying the ecological covering mat 3 in the tree hole of the street tree helps to maintain soil moisture around the street tree, and can also effectively store rainwater, improve the water utilization efficiency of gardening and greening, realize the harmless treatment and resource utilization of garden waste, save natural resources, prevent environmental pollution, and also provide a new way for the resource utilization of garden waste.

[0053] In a possible implementation, the particle size of the garden waste after crushing and screening is 0-1 cm.

[0054] Specifically, the particle size of garden waste after crushing and screening is 0-1cm. Selecting small-size garden waste to prepare ecological covering mats can ensure the water retention effect of the ecological covering mats during use. After small-particle garden waste is compacted by heavy objects, it has better water retention effect than large-particle garden waste due to its small particles.

[0055] In a possible implementation, the weight ratio of the water-based polyurethane adhesive to the garden waste is 3:10.

[0056] It should be understood that the weight ratio of water-based polyurethane adhesive to garden waste is 3:10. After the water-based polyurethane adhesive and garden waste in the above ratio are evenly mixed, they are put into a ring-shaped plastic mold that meets the size of the tree hole, compacted with a heavy object, allowed to air-dry and bond into shape. The addition of water-based polyurethane adhesive can make small particles of garden waste well bonded and formed.

[0057] In a possible implementation, the drying time of the ecological covering mat is 48 hours. After the ecological covering mat is compacted and formed, it is placed in a dry and ventilated place to dry naturally for 48 hours, so that the ecological covering mat can be bonded and formed, and is convenient for use.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
