Description

Technical Field

[0001] The present invention relates to the technical field of cement poles, and more specifically, to a device for preventing freezing and thawing. Background Art

[0002] In frozen soil areas, especially in high latitudes and high altitudes, the existence of seasonal or perennial frozen soil poses severe challenges to all types of engineering construction. Frost heave and thaw settlement are two main problems facing engineering structures in frozen soil areas, which seriously affect the stability and durability of the projects.

[0003] As the global climate warms, temperature fluctuations in permafrost areas are becoming more frequent and severe, which further aggravates the hazards of frost heave and thaw settlement. Frost heave usually occurs in cold seasons. When the water in the soil freezes into ice, the volume of the ice expands, generating an upward lifting force that acts on the foundation structure buried underground. For shallow foundations of buildings, electric pole foundations, oil pipeline foundations, and road and railway subgrades, this frost heave force may cause the foundation to be pulled out of the ground, causing the structure to tilt, deform, or even be damaged, seriously affecting its normal use function and safety. For example, in some transmission lines, electric poles tilt due to frost heave, causing the line to short-circuit and trip, affecting the stability of the power supply; frost heave of the highway subgrade will cause the road surface to be uneven, affecting driving comfort and traffic safety, causing vehicle driving bumps, 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 rises, the permafrost begins to melt, resulting in thaw settlement. As the ice in the permafrost melts, the soil volume decreases, resulting in a decrease in the bearing capacity of the foundation soil. The originally stable foundation structure will settle. This uneven settlement may cause problems such as wall cracking and door and window deformation for buildings, reducing the structural integrity of the building and residential safety. For railway and highway projects, thaw settlement will cause dents and cracks in the tracks and road surfaces, seriously affecting the smoothness of the line, which will not only increase the driving resistance and energy consumption of trains and vehicles, but may also cause safety accidents such as derailment, causing great interference and losses to transportation.

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

[0006] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to propose an anti-freezing and anti-melting sinking device, which can realize the anti-melting sinking function and improve the service life of the pole body.

Since the frost heaving force is formed when the water in the soil freezes, ice crystals will be formed, and the volume of ice crystals is larger than that of water, thereby generating expansion pressure, so the contact Due to the large area, the water in the soil has a relatively wider space to expand when it is frozen, and the frost heave force will be relatively dispersed, and the effect on the soil will be relatively weak, thereby realizing the function of anti-freeze pull. At the same time, because the connecting mechanism is laterally embedded in the soil, the tangential force generated by the frost heave force will be overcome, thereby further improving the anti-freeze pull ability of the soil. In addition, the connecting mechanism can fix the height of the casing and the pole body. Therefore, when thawing settlement occurs, the connecting mechanism can also pull the pole body and the casing to avoid the sinking of the pole body and the casing, thereby realizing the function of anti-thawing settlement and improving the overall service life of the pole body, thereby ensuring the safe and reliable operation of the power system in cold areas and reducing various losses and risks caused by freeze-thaw disasters.

In addition, the design of the solid end head can also squeeze the second connecting rod, so that when the pole body is installed into the inner wall of the casing, pressure is automatically applied to the second connecting rod step by step, so that the second connecting rod is embedded in the pole body. Such a design can not only guide the installation of the pole body into the casing, facilitating the installation of the pole body into the interior of the casing, but also serve as the power for the connecting mechanism to be embedded in the pole body.

Through the control mechanism, during the process of installing the pole body into the casing, the solid end can squeeze the first support plate, drive the first support plate to move, thereby pulling the first connecting rod to move downward. The downward movement of the first connecting rod can drive the wedge block to move downward, so that the wedge block is embedded between the pole body and the casing, thereby fixing the pole body, so that the casing and the pole body can form a whole, increase the overall weight of the casing, thereby further overcoming the frost heave force, preventing the pole body from being pulled out from the inside of the soil, 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 arranged below the first support plate, a second spring is fixedly installed at the bottom end of the second support plate, a third support plate is fixedly installed at the bottom end of the second spring, the second support plate and the third support plate are both slidably installed on the inner wall of the casing, a circular hole is opened on the inner wall of the second support plate, and a maintenance mechanism is arranged inside the circular hole; through the provided buffer mechanism, when freeze pull occurs, the frozen soil can squeeze the third support plate, so that the third support plate slides inside the casing, giving the soil enough space to hold the soil, thereby converting the force generated by frost heave into the elastic potential energy of the second spring and the kinetic energy of the third support plate, avoiding the freeze heave force directly pushing the pole body, causing the pole body to produce freeze pull; in addition, when thawing sinking occurs, the elastic potential energy of the second spring can be released, thereby squeezing the soil; when the soil is squeezed unevenly, it will not affect the stability of the upper pole body, thereby improving the overall stability of the pole body and the casing.

[0014] In a preferred technical solution of the present invention, the maintenance mechanism includes a storage groove arranged on the inner wall of the circular hole, the top of the storage groove is fixedly installed on the bottom end of the first support plate, the bottom end of the storage groove is provided with a sealing plate, the top of the sealing plate is fixedly installed with a guide plate, the top of the guide plate is fixedly installed with a control rod, the control rod passes through the first support plate and extends to the top of the first support plate, the control rod is slidably connected with the first support plate, and the storage groove contains a desiccant; such a design can automatically open the bottom end of the storage groove when the soil body is installed inside the casing, so that the desiccant inside the storage groove enters between the second support plate and the third support plate, compared with placing the desiccant between the second support plate and the third support plate before installation, the contact time between the desiccant and the external air can be reduced, thereby improving the service life of the desiccant, in addition, opening after installation can dry the air in the sealed space between the second support plate and the third support plate, so that the space between the second support plate and the third support plate is in a relatively dry state, avoiding the problem that the second spring is in a humid environment for a long time, is easily corroded, and causes damage, thereby 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 top diameter smaller than a bottom diameter. Such a design enables the desiccant to move downward along the inclined surface of the guide plate during the downward movement of the guide plate, thereby making the desiccant fall from the guide plate over a larger area, thereby achieving a better drying effect of the desiccant.

[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 tank, and the diameter of the sealing plate is smaller than the inner wall diameter of the circular hole. When the sealing plate is in contact with the bottom of the storage tank, a closed cavity can be formed to store the desiccant. At the same time, when the sealing plate 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 be sprinkled, thereby improving the drying effect. In addition, the size needs to be smaller than the circular hole, so as to facilitate the installation of the second support plate into the interior of the casing.

[0018] In a preferred technical solution of the present invention, a limit block is fixedly installed on the outer wall of the control rod, and the limit block is embedded in the inner wall of the limit groove. The limit groove is opened on the inner wall of the first support plate, and the limit block and the limit groove are connected by a third spring. Such a design can limit the position of the control rod, and can also keep the sealing plate and the storage slot in a fitted state without being squeezed by the solid end.

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

[0020] The present invention provides an anti-freezing and anti-thawing device, which can fix the casing inside the soil through the cooperation of the arranged connecting mechanism and the casing, so that in winter, when frost heaving force is generated, the frost heaving force can only act directly on the casing but cannot act directly on the soil, and the contact area between the side of the casing and the soil is large. Since the frost heaving force is formed when the water in the soil freezes, ice crystals will be formed. The volume of ice crystals is larger than that of water, thereby generating expansion pressure. Therefore, the contact area is large, and 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 will be relatively At the same time, since the connecting mechanism is laterally embedded in the soil, the tangential force generated by the frost heave force will be overcome, thereby further improving the soil's ability to resist frost pull. In addition, the connecting mechanism can fix the height of the casing and the pole body. Therefore, when thawing and sinking occur, the connecting mechanism can also pull the pole body and the casing to avoid sinking of the pole body and the casing, thereby realizing the anti-thawing and sinking function and improving the overall service life of the pole body, thereby ensuring the safe and reliable operation of the power system in cold areas and reducing various losses and risks caused by freeze-thaw disasters.

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

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] Embodiment 1

[0033] like Figure 1-Figure 7 As shown, the present invention provides an anti-freezing pull and anti-thawing sinking device, comprising a soil body 1 and a pole body 2, a mounting hole 28 is opened on the soil body 1, a casing 4 is placed inside the mounting hole 28, the casing 4 is connected to the soil body 1 through a connecting mechanism, a pole body 2 is arranged inside the casing 4, a solid end 5 is fixedly installed at the bottom end of the pole body 2, and a control mechanism for controlling the fixing of the pole body 2 is arranged inside the casing 4;

[0034] The connecting 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 placed outside the casing 4, and the other end of the second connecting rod 24 is placed inside the casing 4. The end of the second connecting rod 24 placed inside the casing 4 is fixedly installed with a spherical head 23, and the end of the second connecting rod 24 placed outside the casing 4 is fixedly installed with a drill bit 25.

[0035] By cooperating with the connecting mechanism and the casing 4, the casing 4 can be fixed inside the soil 1, so that in winter, when frost heaving force is generated, the frost heaving force can only act directly on the casing 4, and cannot act directly on the soil 1. The contact area between the side of the casing 4 and the soil 1 is large. Since the frost heaving force is formed when the water in the soil freezes, ice crystals will be formed. The volume of ice crystals is larger than that of water, thereby generating expansion pressure. Therefore, the contact area is large, and the water in the soil can have a relatively wider space to expand when freezing. The frost heaving force will be relatively dispersed, and the effect on the soil 1 will be relatively weak, thereby achieving anti-freeze. The function of frost pullout. At the same time, since the connecting mechanism is laterally embedded in the soil 1, the tangential force generated by the frost heave force will be overcome, thereby further improving the anti-freeze pullout ability of the soil 1. In addition, the connecting mechanism can fix the height of the casing 4 and the pole body 2. Therefore, when thawing and sinking occur, the connecting mechanism can also pull the pole body 2 and the casing 4 to prevent the pole body 2 and the casing 4 from sinking, thereby realizing the anti-thawing and sinking function, and improving the overall service life of the pole body 2, thereby ensuring the safe and reliable operation of the power system in cold areas and reducing various losses and risks caused by freeze-thaw disasters.

[0036] like Figure 4 and Figure 7 As shown, the surface of the second connecting rod 24 is provided with two sections of threads, and the threads are respectively placed inside and outside the casing 4, and the outer wall of the threads is sleeved with a first threaded sleeve 26 and a second threaded sleeve 27, and the outer wall diameter of the first threaded sleeve 26 and the second threaded sleeve 27 is larger than the diameter of the hole on the casing 4.

[0037] Such a design can facilitate the installation of the second connecting rod 24 to the side wall of the casing 4 before construction. It is only necessary 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] like Figure 1-Figure 7 As shown, the solid end head 5 in the figure is a cylinder with a bottom radius smaller than the top radius. First, the solid end head 5 is embedded into the interior of the casing 4, so as to facilitate the installation of the pole body 2 into the interior of the casing 4. In addition, the design of the solid end head 5 can also squeeze the second connecting rod 24, so that when the pole body 2 is installed into the inner wall of the casing 4, pressure is automatically applied to the second connecting rod 24 step by step, so that the second connecting rod 24 is embedded in the pole body 2. Such a design can not only guide the installation of the pole body 2 into the casing 4, which facilitates the installation of the pole body 2 into the casing 4, but also serve as a power for the connecting mechanism to be embedded in the pole body 2.

[0039] like Figure 4 and Figure 6 As shown, the control mechanism in the figure 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 slide groove 7, and a guide rod 8 is fixedly installed on the inner wall of the first slide groove 7. The guide rod 8 passes through the upper and lower sides of the first support plate 6, and the guide rod 8 is placed on the outer wall below the first support plate 6 and is sleeved with a first spring 9. A first connecting rod 10 is fixedly installed on the top of the first support plate 6, and the top of the first connecting rod 10 passes through the connecting terminal 3 and is embedded in the inner wall of the second slide groove 11. The connecting terminal 3 is arranged at the top of the casing 4, and the second slide groove 11 is opened at the top of the wedge block 12. The wedge block 12 is slidably embedded in the inner wall of the connecting terminal 3, and the wedge block 12 is tightly fitted with the outer wall of the pole body 2. A buffer mechanism is arranged below the first support plate 6.

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

[0041] Embodiment 2

[0042] like Figure 4and Figure 6 As shown, 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 on the bottom end of the second support plate 13, a third support plate 15 is fixedly installed on the bottom end of the second spring 14, the second support plate 13 and the third support plate 15 are both slidably installed on the inner wall of the casing 4, a circular hole 22 is opened on the inner wall of the second support plate 13, and a maintenance mechanism is arranged inside the circular hole 22.

[0043] By setting up the buffer mechanism, when the freeze pull phenomenon occurs, the frozen soil can squeeze the third support plate 15, so that the third support plate 15 slides inside the casing 4, giving enough space for the soil, thereby converting the force generated by the frost heave into the elastic potential energy of the second spring 14 and the kinetic energy of the third support plate 15, avoiding the frost heave force directly pushing the pole body 2 and causing the pole body 2 to produce the freeze pull phenomenon. In addition, when the thaw settlement phenomenon occurs, the elastic potential energy of the second spring 14 can be released, thereby squeezing the soil. When the soil is squeezed unevenly, it will not affect the stability of the upper pole body 2, thereby improving the overall stability of the pole body 2 and the casing 4, thereby ensuring the safe and reliable operation of the power system in cold areas and reducing various losses and risks caused by freeze-thaw disasters.

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

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

[0046] The guide plate 20 is a cylinder with a top diameter smaller than a bottom diameter. This design allows the desiccant to move downward along the slope of the guide plate 20 during the downward movement of the guide plate 20, thereby making the desiccant fall from the guide plate 20 over a larger area, thereby achieving a better drying effect of the desiccant.

[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 is in contact with the bottom of the storage groove 19, a closed cavity can be formed to store the desiccant. At the same time, when the sealing plate 21 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 be sprinkled, thereby improving the drying effect. In addition, the size needs to be smaller than the circular hole 22, so as 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, the arc-shaped surface of the wedge block 12 is set to be soft, and the 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, thereby adjusting the shape of the arc surface, so that the arc surface fits better with the outer wall of the pole body 2, thereby fixing it more firmly.

[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. Such a design can limit the position of the control rod 16, and can also keep the sealing plate 21 and the storage groove 19 in a fitted state without being squeezed by the solid end 5.

[0050] Working principle: When it is necessary to install the pole body 2, first use a drilling machine to open the installation hole 28 on the soil body 1, and assemble the casing 4 on one side while drilling. 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, and then respectively sleeve the second threaded sleeve 27 and the first threaded sleeve 26 on the thread of the outer wall of the second connecting rod 24, so that the second connecting rod 24 is simply fixed to one side of the casing 4, and then repeat the above operation to evenly install all the second connecting rods 24 on the side wall of the casing 4, and then place the second support plate 13, the second spring 14 and the third support plate 15 on the inner wall of the bottom end of the casing 4, and 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, and then backfill the soil, and compact the backfill soil to fix the casing 4 in the installation hole 28.

[0051] Then, the pole body 2 is lifted by a crane, placed just above the casing 4, and then slowly lowered. During the lowering process, the solid end 5 squeezes the spherical head 23, so that the spherical head 23 drives the second connecting rod 24 and the drill bit 25 to move, thereby drilling 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, the solid end 5 squeezes the control rod 16, so that the control rod 16 moves downward. The downward movement of the control rod 16 drives the guide plate 20 and the sealing plate 21 to move downward, so that the sealing plate 21 is separated from the bottom end of the storage tank 19. At this time, the desiccant inside the storage tank 19 will flow along the guide plate 20 and The sealing plate 21 falls between the third support plate 15 and the second support plate 13, thereby removing moisture in the space between the third support plate 15 and the second support plate 13, so that the space between the second support plate 13 and the third support plate 15 remains 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 slide groove 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, fixing the pole body 2, and thus realizing the installation of the pole body 2.
