An anti-freezing and anti-thawing settlement device

Abstract

The present invention discloses an anti-freezing-pulling and anti-thawing-settlement device, belonging to the technical field of cement poles, which includes a soil body and a pole main body. An installation hole is formed in the soil body, and a casing is placed inside the installation hole. The casing is connected to the soil body through a connection mechanism; in the present invention, through the mutual cooperation of the provided connection mechanism and the casing, the casing can be fixed inside the soil body, so that in winter, when the frost heaving force is generated, the frost heaving force can only act directly on the casing and cannot act directly on the soil body, thereby realizing the function of anti-freezing-pulling. At the same time, since the connection mechanism is horizontally embedded in the soil body, the tangential force generated by the frost heaving force can be overcome, thereby further improving the anti-freezing-pulling ability of the soil body. In addition, the connection mechanism can fix the heights of the casing and the pole main body. Therefore, when the thawing settlement phenomenon occurs, the connection mechanism can also pull the pole main body and the casing, thereby realizing the function of anti-thawing-settlement and improving the overall service life of the pole main body.

Description

Technical Field

[0001] The present invention relates to the technical field of cement poles, and more specifically, to an anti-freezing and anti-sinking device. Background Art

[0002] In permafrost regions, especially in high-latitude and high-altitude areas, the existence of seasonal or permafrost poses severe challenges to various engineering constructions. Frost heaving and thaw settlement are two major problems faced by engineering structures in permafrost regions, seriously affecting the stability and durability of engineering projects.

[0003] With the global warming, the temperature fluctuations in permafrost regions become more frequent and intense, further exacerbating the hazards of frost heaving and thaw settlement. Frost heaving usually occurs in the cold season. When the water in the soil freezes into ice, the volume of the ice body expands, generating an upward lifting force acting on the foundation structure buried underground. For shallow foundations of buildings, pole foundations, oil pipeline foundations, and roadbeds of highways and railways, this frost heaving force may cause the foundation to be pulled out of the ground, resulting in the structure tilting, deforming, or even being damaged, seriously affecting its normal use function and safety. For example, in some transmission lines, poles tilt due to frost heaving, causing short circuits and tripping of the lines, affecting the stability of power supply; frost heaving of highway roadbeds will cause the road surface to be uneven, affecting driving comfort and traffic safety, resulting in bumpy vehicle driving, and even causing traffic accidents. At the same time, it will also greatly increase the maintenance cost and repair frequency of the road.

[0004] In the season when the temperature warms up, the permafrost begins to melt, resulting in thaw settlement. Since the volume of the soil decreases after the ice in the permafrost melts, the bearing capacity of the foundation soil decreases, and the originally stable foundation structure will settle accordingly. This uneven settlement may cause problems such as wall cracking and door and window deformation for buildings, reducing the structural integrity and living safety of buildings; for railway and highway projects, thaw settlement will cause depressions and cracks in the tracks and road surfaces, seriously affecting the smoothness of the lines. It not only increases the driving resistance and energy consumption of trains and vehicles, but also may cause safety accidents such as derailment, causing great interference and losses to transportation.

[0005] At present, for the problems of frost heaving and thaw settlement, some existing solutions have many limitations. Traditional measures of deepening or enlarging the foundation, although they can increase the anti-heaving and anti-settlement capabilities of the foundation to a certain extent, are often costly, difficult to construct, and it is more difficult to implement the transformation of some existing engineering structures. In addition, simply relying on improving the properties of the foundation soil, such as using the replacement method to replace the permafrost with other soils with better stability, will not only damage the local ecological environment, but also have limited effects and it is difficult to effectively cope with the complex and changeable permafrost environment in the long term, and cannot fundamentally solve the problems of frost heaving and thaw settlement. Summary of the Invention

[0006] To overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide an anti-freezing and anti-thaw settlement device, which can achieve the anti-thaw settlement function and improve the service life of the pole body.

[0007] To achieve this purpose, the present invention adopts the following technical solutions:

[0008] The present invention provides an anti-freezing and anti-thaw settlement device, including a soil body and a pole body. An installation hole is provided in the soil body, and a casing is placed inside the installation hole. The casing is connected to the soil body through a connection mechanism. The pole body is provided inside the casing. A solid end is fixedly installed at the bottom end of the pole body. A control mechanism for controlling the fixation of the pole body is provided inside the casing;

[0009] The connection mechanism includes a second connecting rod provided on the side wall of the casing. One end of the second connecting rod is placed outside the casing, and the other end of the second connecting rod is placed inside the casing. A spherical head is fixedly installed at the end of the second connecting rod placed inside the casing, and a drill bit is fixedly installed at the end of the second connecting rod placed outside the casing. Through the mutual cooperation of the provided connection mechanism and the casing, the casing can be fixed inside the soil body. Thus, in winter, when the frost heaving force is generated, the frost heaving force can only act directly on the casing and cannot act directly on the soil body. The contact area between the side of the casing and the soil body is large. Since the frost heaving force is generated when the water in the soil freezes to form ice crystals, and the volume of the ice crystals is larger than that of water, resulting in an expansion pressure. Therefore, with a large contact area, the water in the soil can have a relatively wider space to expand when freezing, and the frost heaving force will be relatively dispersed, and the effect on the soil body will be relatively weak, thereby realizing the function of anti-freezing and pulling. At the same time, since the connection mechanism is horizontally embedded in the soil body, the tangential force generated by the frost heaving force can be overcome, thereby further improving the anti-freezing and pulling ability of the soil body. In addition, the connection mechanism can fix the heights of the casing and the pole body. Therefore, when the thaw settlement phenomenon occurs, the connection mechanism can also pull the pole body and the casing to prevent the pole body and the casing from sinking, thereby realizing the function of anti-thaw settlement, improving the overall service life of the pole body, and ensuring the safe and reliable operation of the power system in cold regions, reducing various losses and risks brought by freeze-thaw disasters.

[0010] In a preferred technical solution of the present invention, two sections of threads are provided on the surface of the second connecting rod, and the threads are respectively placed inside and outside the casing. The outer walls of the first threaded sleeve and the second threaded sleeve are sleeved on the outer wall of the thread. The outer wall diameters of the first threaded sleeve and the second threaded sleeve are larger than the diameter of the hole on the casing; designed in this way, it is convenient to install the second connecting rod on the side wall of the casing before construction. Only need to pass the second connecting rod through the casing, and then install the first threaded sleeve and the second threaded sleeve on the outer wall of the second connecting rod to form a limiting structure.

[0011] In a preferred technical solution of the present invention, the solid end is a cylinder with a bottom radius smaller than the top radius. First, the solid end is embedded into the inside of the casing, which facilitates the installation of the pole body into the inside of the casing. In addition, the design of the solid end can also squeeze the second connecting rod, so that when the pole body is installed into the inner wall of the casing, pressure is gradually applied to the second connecting rod automatically, causing the second connecting rod to be embedded into the pole body. Such a design can not only play a guiding role in installing the pole body into the casing, facilitating the installation of the pole body into the inside of the casing, but also serve as the power for the connecting mechanism to be embedded into the pole body.

[0012] In a preferred technical solution of the present invention, the control mechanism includes a first support plate arranged inside the casing. Both ends of the first support plate are slidably embedded in the inner wall of the first chute. A guiding rod is fixedly installed on the inner wall of the first chute. The guiding rod penetrates through the upper and lower sides of the first support plate. A first spring is sleeved on the outer wall of the guiding rod below the first support plate. The top of the first support plate is fixedly installed with a first connecting rod. The top of the first connecting rod passes through the connecting end and is embedded in the inner wall of the second chute. The connecting end is arranged at the top of the casing. The second chute is opened at the top of the wedge block. The wedge block is slidably embedded in the inner wall of the connecting end. The wedge block is in close contact with the outer wall of the pole body. A buffer mechanism is arranged below the first support plate; through the arranged control mechanism, during the process of installing the pole body into the inside of the casing, the solid end will squeeze the first support plate, driving the first support plate to move, thereby pulling the first connecting rod downward. The downward movement of the first connecting rod will drive the wedge block to move downward, causing the wedge block to be embedded between the pole body and the casing, thereby fixing the pole body, enabling the casing and the pole body to form an integral body, increasing the overall weight of the casing, further overcoming the frost heaving force, preventing the pole body from being pulled out from the inside of the soil body, and improving the service life of the pole body.

[0013] In a preferred technical solution of the present invention, the buffer mechanism includes a second support plate disposed below the first support plate. A second spring is fixedly installed at the bottom end of the second support plate, and a third support plate is fixedly installed at the bottom end of the second spring. Both the second support plate and the third support plate are slidably installed on the inner wall of the casing. A circular hole is formed in the inner wall of the second support plate, and a maintenance mechanism is disposed inside the circular hole. By providing the buffer mechanism, when the frost heaving phenomenon occurs, the frozen soil can squeeze the third support plate, causing the third support plate to slide inside the casing, providing sufficient space for the soil to be contained, thereby converting the force generated by frost heaving into the elastic potential energy of the second spring and the kinetic energy of the third support plate, avoiding the direct pushing of the pole main body by the frost heaving force and resulting in the frost heaving phenomenon of the pole main body. In addition, when the thaw settlement phenomenon occurs, the elastic potential energy of the second spring is released, thereby squeezing the soil. Even when the soil is squeezed unevenly, it will not affect the stability of the pole main body above, improving the overall stability of the pole main body and the casing.

[0014] In a preferred technical solution of the present invention, the maintenance mechanism includes a storage groove disposed on the inner wall of the circular hole. The top end of the storage groove is fixedly installed at the bottom end of the first support plate. A sealing plate is disposed at the bottom end of the storage groove. A guide plate is fixedly installed at the top end of the sealing plate, and a control rod is fixedly installed at the top end of the guide plate. The control rod passes through the first support plate and extends above the first support plate. The control rod is slidably connected to the first support plate. A desiccant is contained inside the storage groove. With such a design, when the soil body is installed inside the casing, the bottom end of the storage groove can be automatically opened, enabling the desiccant inside the storage groove to enter between the second support plate and the third support plate. Compared with putting the desiccant between the second support plate and the third support plate before installation, it can reduce the contact time of the desiccant with the external air, thereby increasing the service life of the desiccant. In addition, opening it after installation can dry the air in the sealed space between the second support plate and the third support plate, keeping the space between the second support plate and the third support plate in a relatively dry state, avoiding the problem that the second spring is easily corroded and damaged when it is in a humid environment for a long time, and improving the service life of the second spring.

[0015] In a preferred technical solution of the present invention, the guide plate is a cylinder with a smaller top diameter than the bottom diameter. With such a design, when the guide plate moves downward, the desiccant can move downward along the inclined surface of the guide plate, so that the area where the desiccant falls from the guide plate is larger, making the drying effect of the desiccant better.

[0016] In a preferred technical solution of the present invention, the diameter of the sealing plate is larger than the outer wall diameter of the storage groove, and the diameter of the sealing plate is smaller than the inner wall diameter of the circular hole. When the sealing plate fits with the bottom of the storage groove, a sealed cavity can be formed for storing desiccant. At the same time, when it is opened, the desiccant can fall along the sealing plate. Therefore, the larger the size of the sealing plate, the larger the area where the desiccant can spill, thereby improving the drying effect. In addition, the size needs to be smaller than the circular hole to facilitate the installation of the second support plate into the inside of the protection cylinder.

[0017] In a preferred technical solution of the present invention, the inner wall of the wedge block is set to be arc-shaped, and the arc surface of the wedge block is set to be soft, and other positions are hard. With such a design, when the wedge block is pushed by the first connecting rod, the wedge block can be continuously squeezed during the downward movement, so as to adjust the shape of the arc surface, making the arc surface fit more closely with the outer wall of the pole body, and thus the fixation is more firm.

[0018] In a preferred technical solution of the present invention, a limiting block is fixedly installed on the outer wall of the control rod, the limiting block is embedded in the inner wall of the limiting groove, the limiting groove is opened on the inner wall of the first support plate, and the limiting block and the limiting groove are connected by a third spring. With such a design, the position of the control rod can be limited, and the sealing plate and the storage groove can be in a fitting state without being squeezed by the solid end.

[0019] The beneficial effects of the present invention are as follows:

[0020] The present invention provides an anti-freezing and anti-thawing settlement prevention device. By the mutual cooperation of the provided connecting mechanism and the protection cylinder, the protection cylinder can be fixed inside the soil body. Thus, in winter, when the frost heaving force is generated, the frost heaving force can only act directly on the protection cylinder and cannot act directly on the soil body. The contact area between the side of the protection cylinder and the soil body is large. Since the frost heaving force is generated when the water in the soil freezes to form ice crystals, and the volume of the ice crystals is larger than that of water, resulting in an expansion pressure. Therefore, with a large contact area, the water in the soil can have a relatively wider space to expand when freezing, and the frost heaving force will be relatively dispersed and have a relatively weak effect on the soil body, thereby realizing the function of anti-freezing and pulling. At the same time, since the connecting mechanism is horizontally embedded in the soil body, the tangential force generated by the frost heaving force can be overcome, thereby further improving the anti-freezing and pulling ability of the soil body. In addition, the connecting mechanism can fix the heights of the protection cylinder and the pole body. Therefore, when the thaw settlement phenomenon occurs, the connecting mechanism can also pull the pole body and the protection cylinder to prevent the pole body and the protection cylinder from sinking, thereby realizing the function of anti-thaw settlement, improving the overall service life of the pole body, and ensuring the safe and reliable operation of the power system in cold regions, reducing various losses and risks caused by freeze-thaw disasters.

[0021] By setting up a maintenance mechanism, when the soil body is installed inside the casing, the bottom end of the storage tank can be automatically opened, so that the desiccant inside the storage tank enters between the second support plate and the third support plate. Compared with putting the desiccant between the second support plate and the third support plate before installation, it can reduce the contact time of the desiccant with the external air, thereby improving the service life of the desiccant. In addition, opening it after installation can dry the air in the sealed space between the second support plate and the third support plate, making the space between the second support plate and the third support plate in a relatively dry state, avoiding the problem that the second spring is easily corroded and damaged when it is in a humid environment for a long time, and improving the service life of the second spring.

Detailed Embodiment

[0031] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0032] Example 1

[0033] As Figures 1-7 shown, the present invention provides an anti-freezing and anti-thawing settlement device, which includes a soil body 1 and a pole main body 2. An installation hole 28 is formed in the soil body 1, and a casing 4 is placed inside the installation hole 28. The casing 4 is connected to the soil body 1 through a connection mechanism. The pole main body 2 is arranged inside the casing 4. A solid end 5 is fixedly installed at the bottom end of the pole main body 2. A control mechanism for controlling the fixation of the pole main body 2 is arranged inside the casing 4;

[0034] The connection mechanism includes a second connecting rod 24 arranged on the side wall of the casing 4. One end of the second connecting rod 24 is located outside the casing 4, and the other end of the second connecting rod 24 is located inside the casing 4. A spherical head 23 is fixedly installed at the end of the second connecting rod 24 located inside the casing 4, and a drill bit 25 is fixedly installed at the end of the second connecting rod 24 located outside the casing 4.

[0035] Through the mutual cooperation of the arranged connection mechanism and the casing 4, the casing 4 can be fixed inside the soil body 1. Thus, in winter, when the frost heaving force is generated, the frost heaving force can only act directly on the casing 4 and cannot act directly on the soil body 1. The contact area between the side surface of the casing 4 and the soil body 1 is large. Since the frost heaving force is generated when the water in the soil freezes to form ice crystals, and the volume of the ice crystals is larger than that of water, resulting in an expansion pressure. Therefore, with a large contact area, the water in the soil can have a relatively wider space to expand when freezing, and the frost heaving force will be relatively dispersed, and the effect on the soil body 1 will be relatively weak, thereby realizing the function of anti-freezing pull-out. At the same time, since the connection mechanism is horizontally embedded in the soil body 1, the tangential force generated by the frost heaving force can be overcome, thereby further improving the anti-freezing pull-out ability of the soil body 1. In addition, the connection mechanism can fix the heights of the casing 4 and the pole main body 2. Therefore, when the thaw settlement phenomenon occurs, the connection mechanism can also pull the pole main body 2 and the casing 4 to avoid the sinking of the pole main body 2 and the casing 4, thereby realizing the function of anti-thaw settlement, improving the overall service life of the pole main body 2, and ensuring the safe and reliable operation of the power system in cold regions, reducing various losses and risks brought by freeze-thaw disasters.

[0036] As Figure 4 shown in Figure 7 the figure, two sections of threads are provided on the surface of the second connecting rod 24, and the threads are respectively located inside and outside the casing 4. The outer walls of the threads are sleeved with a first thread sleeve 26 and a second thread sleeve 27, and the outer diameters of the outer walls of the first thread sleeve 26 and the second thread sleeve 27 are larger than the diameter of the hole on the casing 4.

[0037] With such a design, it is convenient to install the second connecting rod 24 on the side wall of the casing 4 before construction. It only needs to pass the second connecting rod 24 through the casing 4, and then install the first threaded sleeve 26 and the second threaded sleeve 27 on the outer wall of the second connecting rod 24 to form a limiting structure.

[0038] As Figures 1-7 shown, in the figure, the solid end 5 is a cylinder with a bottom radius smaller than the top radius. First, embed the solid end 5 into the inside of the casing 4, so as to facilitate the installation of the pole body 2 into the inside of the casing 4. In addition, the design of the solid end 5 can also squeeze the second connecting rod 24, so that when the pole body 2 is installed on the inner wall of the casing 4, pressure is gradually applied to the second connecting rod 24 automatically, so that the second connecting rod 24 is embedded into the pole body 2. With such a design, it can not only play a guiding role in installing the pole body 2 into the casing 4, facilitating the installation of the pole body 2 into the inside of the casing 4, but also serve as the power for the connecting mechanism to be embedded into the pole body 2.

[0039] As Figure 4 With Figure 6 shown, in the figure, the control mechanism includes a first support plate 6 arranged inside the casing 4. Both ends of the first support plate 6 are slidably embedded in the inner wall of the first chute 7. A guide rod 8 is fixedly installed on the inner wall of the first chute 7. The guide rod 8 penetrates through the upper and lower sides of the first support plate 6. A first spring 9 is sleeved on the outer wall of the guide rod 8 below the first support plate 6. The top of the first support plate 6 is fixedly installed with a first connecting rod 10. The top of the first connecting rod 10 passes through the connecting end 3 and is embedded in the inner wall of the second chute 11. The connecting end 3 is arranged at the top of the casing 4. The second chute 11 is opened at the top of the wedge 12. The wedge 12 is slidably embedded in the inner wall of the connecting end 3. The wedge 12 is in close contact with the outer wall of the pole body 2. A buffer mechanism is arranged below the first support plate 6.

[0040] Through the arranged control mechanism, during the process of installing the pole body 2 into the inside of the casing 4, the solid end 5 will squeeze the first support plate 6, drive the first support plate 6 to move, and thus pull the first connecting rod 10 to move downward. The downward movement of the first connecting rod 10 will drive the wedge 12 to move downward, so that the wedge 12 is embedded between the pole body 2 and the casing 4, thereby fixing the pole body 2, enabling the casing 4 and the pole body 2 to form a whole, increasing the overall weight of the casing 4, further overcoming the frost heaving force, preventing the pole body 2 from being pulled out from the inside of the soil body 1, improving the service life of the pole body 2, ensuring the safe and reliable operation of the power system in cold regions, and reducing various losses and risks brought by freeze-thaw disasters.

[0041] Embodiment 2

[0042] As Figure 4As shown in Figure 6 Figure 1, the buffer mechanism in the figure includes a second support plate 13 arranged below the first support plate 6. A second spring 14 is fixedly installed at the bottom end of the second support plate 13, and a third support plate 15 is fixedly installed at the bottom end of the second spring 14. Both the second support plate 13 and the third support plate 15 are slidably installed on the inner wall of the casing 4. A circular hole 22 is formed in the inner wall of the second support plate 13, and a maintenance mechanism is arranged inside the circular hole 22.

[0043] Through the arranged buffer mechanism, when the phenomenon of frost heaving occurs, the frozen soil can squeeze the third support plate 15, causing the third support plate 15 to slide inside the casing 4, giving enough space for the soil to be placed, thereby converting the force generated by frost heaving into the elastic potential energy of the second spring 14 and the kinetic energy of the third support plate 15, avoiding the frost heaving force directly pushing the pole main body 2 and resulting in the frost heaving phenomenon of the pole main body 2. In addition, when the phenomenon of thaw settlement occurs, the elastic potential energy of the second spring 14 is released, thereby squeezing the soil. Even if the soil is squeezed unevenly, it will not affect the stability of the upper pole main body 2, improving the overall stability of the pole main body 2 and the casing 4, and thus ensuring the safe and reliable operation of the power system in cold regions and reducing various losses and risks brought by freeze-thaw disasters.

[0044] The maintenance mechanism includes a storage tank 19 arranged on the inner wall of the circular hole 22. The top end of the storage tank 19 is fixedly installed at the bottom end of the first support plate 6. A sealing plate 21 is arranged at the bottom end of the storage tank 19. A guide plate 20 is fixedly installed at the top end of the sealing plate 21. A control rod 16 is fixedly installed at the top end of the guide plate 20. The control rod 16 passes through the first support plate 6 and extends above the first support plate 6. The control rod 16 is slidably connected with the first support plate 6. A desiccant is placed inside the storage tank 19.

[0045] With such a design, when the soil body 1 is installed inside the casing 4, the bottom end of the storage tank 19 can be automatically opened, so that the desiccant inside the storage tank 19 enters between the second support plate 13 and the third support plate 15. Compared with putting the desiccant between the second support plate 13 and the third support plate 15 before installation, it can reduce the contact time between the desiccant and the external air, thereby increasing the service life of the desiccant. In addition, opening it after installation can dry the air in the sealed space between the second support plate 13 and the third support plate 15, making the space between the second support plate 13 and the third support plate 15 in a relatively dry state, avoiding the problem that the second spring 14 is easily corroded and damaged when it is in a humid environment for a long time, and improving the service life of the second spring 14.

[0046] The guide plate 20 is a cylinder with a smaller top diameter than the bottom diameter. With this design, when the guide plate 20 moves downward, the desiccant can move downward along the inclined surface of the guide plate 20, so that when the desiccant falls from the guide plate 20, the area is larger, and the drying effect of the desiccant is better.

[0047] The diameter of the sealing plate 21 is larger than the outer wall diameter of the storage groove 19, and the diameter of the sealing plate 21 is smaller than the inner wall diameter of the circular hole 22. When the sealing plate 21 fits with the bottom of the storage groove 19, a closed cavity can be formed for storing the desiccant. At the same time, when it is opened, the desiccant can fall along the sealing plate 21. Therefore, the larger the size of the sealing plate 21, the larger the area where the desiccant can spill, thereby improving the drying effect. In addition, the size needs to be smaller than the circular hole 22 to facilitate the installation of the second support plate 13 into the inside of the casing 4.

[0048] The inner wall of the wedge block 12 is set to be arc-shaped, and the arc surface of the wedge block 12 is set to be soft, and other positions are hard. With this design, when the wedge block 12 is pushed by the first connecting rod 10, the wedge block 12 can be continuously squeezed during the downward movement, so as to adjust the shape of the arc surface, making the arc surface fit more closely with the outer wall of the pole body 2, and thus the fixation is more firm.

[0049] A limit block 17 is fixedly installed on the outer wall of the control rod 16. The limit block 17 is embedded in the inner wall of the limit groove 29. The limit groove 29 is opened on the inner wall of the first support plate 6. The limit block 17 and the limit groove 29 are connected by a third spring 18. With this design, the position of the control rod 16 can be limited, and when not being squeezed by the solid end 5, the sealing plate 21 and the storage groove 19 are in a fitting state.

[0050] Working principle: When the pole body 2 needs to be installed, first use a drilling machine to open an installation hole 28 in the soil body 1. While drilling, assemble the casing 4 on one side. First, pass the second connecting rod 24 through the side wall of the casing 4 so that the drill bit 25 faces the outside of the casing 4. Then, sleeved the second thread sleeve 27 and the first thread sleeve 26 on the threaded parts of the outer wall of the second connecting rod 24 respectively, so as to simply fix the second connecting rod 24 to one side of the casing 4. Then repeat the above operation to evenly install all the second connecting rods 24 on the side wall of the casing 4. Then, place the second support plate 13, the second spring 14 and the third support plate 15 into the inner wall of the bottom end of the casing 4. Finally, sink the casing 4 into the installation hole 28 so that the casing 4 is stably placed in the installation hole 28, and use a measuring instrument to adjust the casing 4 to a vertical state. Then backfill the soil and compact the backfill soil to fix the casing 4 in the installation hole 28.

[0051] Then, a crane is used to lift the pole body 2 and place it directly above the casing 4, and then slowly lower it. During the lowering process, the solid end 5 will squeeze the spherical head 23, causing the spherical head 23 to drive the second connecting rod 24 and the drill bit 25 to move, so as to drill into the hard soil until the spherical head 23 moves to the side wall of the pole body 2. When the pole body 2 continues to be lowered, at this time, the solid end 5 will squeeze the control rod 16, causing the control rod 16 to move downward. The downward movement of the control rod 16 will drive the guide plate 20 and the sealing plate 21 to move downward, causing the sealing plate 21 to separate from the bottom end of the storage groove 19. At this time, the desiccant inside the storage groove 19 will fall onto the space between the third support plate 15 and the second support plate 13 along the guide plate 20 and the sealing plate 21, thereby removing the moisture in the space between the third support plate 15 and the second support plate 13, keeping the space between the second support plate 13 and the third support plate 15 dry. The pole body 2 continues to be lowered. At this time, the solid end 5 will squeeze the first support plate 6, driving the first support plate 6 to slide on the inner wall of the first chute 7. When the first support plate 6 slides, it will drive the first connecting rod 10 to slide. The sliding of the first connecting rod 10 will push the wedge block 12 to slide downward, thereby embedding the wedge block 12 between the pole body 2 and the casing 4 to fix the pole body 2, thus realizing the installation of the pole body 2.
