Description

Technical Field

[0001] The utility model relates to a tree root drainage device for afforestation, belonging to the field of forestry. Background Art

[0002] Afforestation is not only an effective means to increase green coverage and improve the ecological environment, but also one of the important ways to cope with climate change and achieve carbon neutrality. In the process of afforestation, the appropriate planting season is selected according to the design, and scientific planting techniques and methods are adopted, such as pit planting, trench planting, strip planting, etc., to ensure the survival rate of seedlings. If there is a large amount of water in the soil around the roots, it will affect the normal production of seedlings. After digging pits around the roots, the water around the roots is collected in the pits, which is convenient for using water pumps and other tools to drain the water in the pits, so as to achieve the purpose of tree root drainage. In order to prevent pits from collapsing, it is common to use casing to support the pits. When the casing is recovered later, the contact range between the casing and the inner wall of the pit is large, which makes the resistance to removing the casing large. Therefore, it is necessary to design a tree root drainage device for afforestation that reduces the resistance to removing the casing. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tree root drainage device for afforestation to solve the problems raised in the above background technology. The utility model reduces the contact area between the casing and the pit wall when removing the casing, thereby reducing the resistance to removing the casing.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a tree root drainage device for afforestation, including a casing, one end of the casing is connected and fixed with an upper ring, the other end of the casing is installed with a lower ring, the casing is provided with an inflatable airbag sleeve, the inflatable airbag sleeve is adhered to the upper ring and the lower ring, a straight tube is provided in the casing along the length direction of the casing, one end of the straight tube extends to the outside of the casing, a connecting tube connected to the straight tube is installed on the outer surface of the straight tube, the end of the connecting tube away from the straight tube passes through the casing and is connected to the space formed by the casing and the inflatable airbag sleeve, a detachable inflation nozzle is installed on the upper end of the straight tube, and a detachable end plate is installed on the lower end of the straight tube.

[0005] Furthermore, an upper flange is connected and fixed to the upper end of the straight pipe, and a lower flange is installed at the lower end of the straight pipe. The upper flange is connected to the flange at one end of the inflation nozzle through multiple bolts, and the upper flange on one straight pipe is connected to the lower flange on another straight pipe through a fastener formed by multiple sets of screws and nuts.

[0006] Furthermore, a supporting flange with a gap between it and the upper flange is provided on the lower side of the upper flange. The supporting flange is sleeved on the straight pipe and fixedly connected to the straight pipe. One end of the screw passes through the lower flange, the upper flange and the supporting flange and is threadedly connected to a nut. The nut is provided on the side of the supporting flange facing away from the upper flange.

[0007] Furthermore, a plurality of plugs are evenly mounted on the upper surface of the upper ring, and a plurality of jacks matching with the plugs are evenly opened on the lower surface of the lower ring.

[0008] Furthermore, the upper ring and the casing are an integrally formed structure, and the lower ring and the casing are an integrally formed structure.

[0009] Furthermore, a plurality of reinforcing ribs are evenly fixed on the outer surface of the straight pipe, and the other ends of the reinforcing ribs are connected and fixed to the casing.

[0010] Furthermore, two lifting ears are symmetrically fixed at the upper inner portion of the casing, and vertical holes are opened on the upper surfaces of the lifting ears.

[0011] Beneficial effects of the utility model:

[0012] 1. Select an appropriate number of casings according to the depth of the pit, stack multiple casings from small to high, and then connect two adjacent straight pipes with screws and nuts. Then install an end plate at the bottom of the lowest straight pipe and an inflation nozzle at the top of the uppermost straight pipe. At this time, multiple straight pipes serve to connect multiple casings, and at the same time, the spaces formed by multiple expansion airbag sleeves and casings are made the same. Multiple casings are assembled to meet the needs of pits of different depths, facilitating the modular design of casings.

[0013] 2. When using a fastener formed by a screw and a nut to connect two adjacent straight pipes, make one end of the screw pass through the lower flange, the upper flange and the support flange and then screw on the nut. At this time, the nut is restricted by the support flange, and there is a gap between the nut and the upper flange. Because one end of the straight pipe with the upper flange installed is outside the casing, when the nut and the screw cannot be disassembled normally due to rust, the gap between the support flange and the upper flange can be used to cut off the screw, which facilitates the disassembly of the two adjacent casings.

[0014] 3. After placing the casing in the foundation pit, connect the inflation nozzle to the inflation tube, and use the inflation tube to inject air into the space formed by the expansion airbag sleeve and the casing, so that the volume of the expansion airbag sleeve expands and contacts the pit wall. When the casing needs to be recovered, open the inflation nozzle to discharge the air in the space formed by the expansion airbag sleeve and the casing. At this time, the volume of the expansion airbag sleeve is reduced, and a gap is generated between the expansion airbag sleeve and the pit wall, thereby reducing the contact range between the casing and the pit wall, which is conducive to reducing the resistance to removing the casing.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-Figure 5 The utility model provides a technical solution: a tree root drainage device for afforestation, including a casing 1, one end of the casing 1 is connected and fixed with an upper ring 3, and the other end of the casing 1 is installed with a lower ring 14, wherein the upper ring 3, the lower ring 14 and the casing 1 are all integrally formed structures, and a plurality of plugs 12 are evenly installed on the upper surface of the upper ring 3, and a plurality of sockets 16 that match the plugs 12 are evenly opened on the lower surface of the lower ring 14. When two adjacent casings 1 are docked, the plugs 12 are inserted into the sockets 16, which improves the stability of the plug-in connection between the two adjacent casings 1, so that the structure formed by the multiple casings 1 is placed in the pit around the tree roots to support the pit wall. The moisture in the soil around the tree roots is collected in the structural space formed by the multiple casings 1, and the moisture in the casing 1 is pumped out by using a water pump to achieve the purpose of drainage.

[0025] See Figures 1-6 The cam 1 is provided with a plurality of screw threads, and the screw thread is fixed on the cam 1, and the screw thread is fixed on the cam 1. The cam 1 is provided with a plurality of screw threads, and the screw thread is fixed on the cam 1. The screw thread is fixed on the cam 1, and the screw thread is fixed on the cam 1. The end plate 13 is installed at the bottom of the lowest straight tube 5, and the inflation nozzle 8 is installed at the upper end of the uppermost straight tube 5. At this time, the multiple straight tubes 5 play the role of connecting multiple casings 1, and at the same time, the space formed by the multiple expansion airbag sleeves 4 and the casing 1 is the same. The multiple casings 1 are assembled, which is suitable for the needs of pits of different depths, facilitating the modular design of the casing 1. After the casing 1 is placed in the foundation pit, the inflation nozzle 8 is connected to the inflation cylinder, and the inflation cylinder is used to inject air into the space formed by the expansion airbag sleeve 4 and the casing 1, so that the volume of the expansion airbag sleeve 4 expands and contacts the pit wall. When the casing 1 needs to be recovered, the inflation nozzle 8 is opened to discharge the air in the space formed by the expansion airbag sleeve 4 and the casing 1. At this time, the volume of the expansion airbag sleeve 4 is reduced, and a gap is generated between the expansion airbag sleeve 4 and the pit wall, thereby reducing the contact range of the casing 1 with the pit wall, which is conducive to reducing the resistance to removing the casing 1.

[0026] See Figure 1-Figure 5, the upper end of the straight pipe 5 is connected and fixed with an upper flange 10, and the lower end of the straight pipe 5 is installed with a lower flange 17. The upper flange 10 is connected to the flange at one end of the inflation nozzle 8 by multiple bolts. The upper flange 10 on one straight pipe 5 is connected to the lower flange 17 on the other straight pipe 5 by a fastener formed by multiple sets of screws 9 and nuts 15, wherein the lower side of the upper flange 10 is provided with a support flange 11 with a gap between it and the upper flange 10. The support flange 11 is sleeved on the straight pipe 5 and connected and fixed to the straight pipe 5. One end of the screw 9 passes through the lower flange 17, the upper flange 10 and the support flange 11 and is threadedly connected to the nut 15. The nut 15 is provided When the fastener formed by the screw 9 and the nut 15 is used to connect the two adjacent straight pipes 5, one end of the screw 9 is passed through the lower flange 17, the upper flange 10 and the support flange 11, and the nut 15 is screwed on. At this time, the nut 15 is restricted by the support flange 11, and there is a gap between the nut 15 and the upper flange 10. Since one end of the straight pipe 5 on which the upper flange 10 is installed is outside the casing 1, when the nut 15 and the screw 9 cannot be disassembled normally due to rust, the gap between the support flange 11 and the upper flange 10 can be used to cut off the screw 9, which facilitates the disassembly of the two adjacent casings 1.
