[0002] In recent years, the extreme climate faced by infrastructure construction has gradually increased. In seasonally frozen soil areas, the frozen soil will melt in warm summers, causing the building foundation to sink and deform. In cold winters, the water in the soil will freeze, causing the building foundation to rise. The uneven distribution of water bodies and the uneven geological characteristics may cause uneven settlement of the building foundation. Transmission towers are the key link in energy transmission in the central and western regions. The stability of the foundation is more stringent and the impact of damage is more serious. Therefore, the construction of transmission tower foundations in seasonally frozen soil areas is an extremely challenging task.

[0003] At present, traditional transmission towers in seasonally frozen areas are generally constructed by deep excavation of foundations, but this method has shortcomings in the following aspects: 1) Frost heave and thaw settlement will always have an impact: Under extreme weather conditions, the depth of the seasonal frozen area will increase, and the thermal conductivity of the pile foundation is higher than that of the soil, which will also cause the temperature of the surrounding soil to drop rapidly, making the pile foundation always affected by the frost heave and thaw settlement phenomenon; 2) Frost heave damage: The soil around the pile foundation will frost and heave, which will produce an extrusion capacity on the foundation structure. On the one hand, it will cause the foundation structure to be damaged, and on the other hand, it may cause non-uniform stress deformation of the foundation, which will lead to uneven horizontal deformation of the pile foundation, and then cause the collapse of the transmission line.

[0030] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1-Figure 6, which is the first embodiment of the present invention, and this embodiment provides a seasonal frozen soil area transmission tower foundation insulation equipment and a construction method thereof. The seasonal frozen soil area transmission tower foundation insulation equipment and a construction method thereof include an insulation component 100, a fastening component 200 and a switching component 300. The insulation component 100 is used to insulate the transmission tower foundation, and the fastening component 200 is used to fix the filter net to improve the filtering effect of rainwater. The switching component 300 can control the rainwater to be added into the heat exchange tube.

[0034] Specifically, the insulation component 100 includes a transmission tower foundation pile 101, a ground source heat pump heat exchange pipe 102, a water collecting pool 103, a water supply pipe 104, a vent pipe 105, a water blocking piece 106, a filter 107 and a receiving piece 108. The ground source heat pump heat exchange pipe 102 is arranged around the transmission tower foundation pile 101, and the water collecting pool 103 is located on one side of the ground source heat pump heat exchange pipe 102. Both ends of the water supply pipe 104 are connected to the ground source heat pump heat exchange pipe 102 and the water collecting pool 103 respectively. One end of the vent pipe 105 is connected to the ground source heat pump heat exchange pipe 102, and the other end extends to one side of the water collecting pool 103. The water blocking piece 106 is arranged in the water supply pipe 104, the filter 107 is arranged in the water collecting pool 103, and the receiving piece 108 is arranged on the inner wall of the water collecting pool 103.

[0035] There are multiple ground source heat pump heat exchange pipes 102, which are pre-buried around the transmission tower foundation pile 101, and the ground source heat pump heat exchange pipes 102 on each side are arranged in a U shape to form an insulation belt, so that the transmission tower foundation pile 101 can reach a normal temperature effect around. One end of the ground source heat pump heat exchange pipe 102 is connected to the ground source heat pump. The present invention provides energy to the ground source heat pump through the transmission tower's own energy to enable it to continuously maintain the heat exchange effect. The working principle of this part is the existing technology and will not be repeated here.

[0036] An open collecting plate is fixed on the top of the water collecting tank 103 to collect rainwater therein. The water supply pipe 104 is at the highest point of the geothermal heat pump heat exchange tube 102. When the air inside the geothermal heat pump heat exchange tube 102 moves upward to the highest point, the water pressure on both sides of the water supply pipe 104 will change, and the water in the water collecting tank 103 will enter the geothermal heat pump heat exchange tube 102 through the water supply pipe 104 to perform water supply operation. At the same time, the vent pipe 105 will discharge the air due to the pressure difference. The water blocking part 106 is set to prevent the water in the geothermal heat pump heat exchange tube 102 from entering the water collecting tank 103. The filter net 107 is used to filter the water in the water collecting tank 103 to prevent impurities from entering the water supply pipe 104 and the geothermal heat pump heat exchange tube 102, which brings great inconvenience to its use. The receiving part 108 is used to place the filter net 107.

[0037] The fastening assembly 200 is arranged in the water collecting pool 103, and includes a side door 201, a movable rod 202, a limit member 203, a fastening plate 204 and a guide member 205. An inspection port S is opened on one side of the water collecting pool 103, the side door 201 is arranged in the inspection port S, the movable rod 202 slides on both sides of the inner wall of the water collecting pool 103, the limit member 203 is arranged on the movable rod 202, the fastening plate 204 slides on both sides of the inner wall of the water collecting pool 103, and the guide member 205 is arranged on the top of the fastening plate 204.

[0038] The side door 201 is rectangular and can be installed in the inspection port S by means of screws, buckles or hinges. When the filter 107 needs to be cleaned or replaced, the side door 201 can be opened to manually take out the filter 107. Two movable rods 202 are provided, and one side of the fastening plate 204 is inclined. The movable rod 202 cooperates with the limit member 203 to push the fastening plate 204 downward. The filter 107 is squeezed and fixed by the fastening plate 204, which can prevent the filter 107 from being misplaced due to the buoyancy of water or the shaking of foreign objects during use, thereby affecting its filtering effect.

[0039] The switching assembly 300 is arranged in the water supply pipe 104, and includes a trigger rod 301, a trigger member 302, a limit frame 303 and a driving member 304. The trigger rod 301 slides on both sides of the inner wall of the water supply pipe 104, and cooperates with the water blocking member 106. The trigger member 302 is arranged on the trigger rod 301, the limit frame 303 slides in the water supply pipe 104, and the driving member 304 is fixed to the top of the limit frame 303.

[0040] Two trigger rods 301 are provided, and the cooperation between the trigger rods 301 and the trigger member 302 can limit the water blocking member 106. When the filter 107 is removed, the water blocking member 106 is reset to a closed state by the trigger rods 301 and the trigger member 302. At the same time, the water blocking member 106 is fixed by the limit frame 303 and the drive member 304 to prevent impurities from entering the water supply pipe 104 and the ground source heat pump heat exchange pipe 102 when cleaning the filter and the water collection tank 103.

[0041] Example 2

[0042] Reference Figure 2 to Figure 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, the water blocking component 106 includes a mounting plate 106a, a connecting rod 106b, a blocking block 106c, a fixing plate 106d and a protrusion 106e. The mounting plate 106a is fixed in the water supply pipe 104, and a water supply hole P is opened in the middle thereof. The connecting rod 106b slides in the water supply hole P, the blocking block 106c is fixed to one end of the connecting rod 106b, the fixing plate 106d is fixed to the other end of the connecting rod 106b, and the protrusion 106e is fixed to the four inner corners of the fixing plate 106d.

[0044] The mounting plate 106a is rectangular, and a rubber ring is fixed on one side of the sealing block 106c close to the water supply hole P, which has a sealing effect. The protrusion 106e ensures that there is always a certain distance between the fixing plate 106d and the water supply hole P, which can prevent the water in the water collection pool 103 from being blocked when entering from the water supply hole P.

[0045] The water blocking member 106 further includes a guide rod 106f and a first spring 106g. The guide rod 106f is fixed to one side of the fixing plate 106d. Both ends of the first spring 106g are respectively fixed to the fixing plate 106d and the mounting plate 106a.

[0046] A sealing treatment is performed between the guide rod 106f and the mounting plate 106a, and the first spring 106g applies a force to the fixing plate 106d in the direction away from the mounting plate 106a, so that when the water pressure on both sides is balanced, that is, when there is no air in the ground source heat pump heat exchange tube 102, the water supply hole P can be blocked by the fixing plate 106d, the mounting plate 106a and the blocking block 106c. When there is air in the ground source heat pump heat exchange tube 102, the water pressure on one side of the fixing plate 106d pushes it toward the mounting plate 106a, thereby opening the water supply hole P and performing the water supply operation.

[0047] The receiving member 108 includes a receiving plate 108a, a drainage plate 108b and a protective plate 108c. The receiving plate 108a is fixed around the inner wall of the water collecting pool 103. The filter screen 107 is located on the receiving plate 108a. The drainage plate 108b is placed on the inner bottom wall of the water collecting pool 103. The protective plate 108c is fixed to the top of the filter screen 107.

[0048] There are multiple receiving plates 108a, which are fixed around the inner wall of the water collecting pool 103 by screws. The cross-section of the drainage plate 108b is inclined, and is used to guide the water at the bottom of the water collecting pool 103 to the water supply pipe 104. There are multiple sedimentation tanks on the top of the drainage plate 108b to collect and precipitate fine impurities that are not completely filtered out by the filter screen 107. At the same time, the drainage plate 108b is detachable and can be removed by the staff for cleaning. The guard plate 108c is used to block the impurities accumulated on the top of the filter screen 107 to avoid excessive impurities from entering the water collecting pool 103 during removal, which causes inconvenience to cleaning.

[0049] The limiting member 203 includes a fixed frame 203a, an inclined plate 203b and a second spring 203c. The fixed frame 203a is fixed on both sides of the inner wall of the water collecting pool 103. The movable rod 202 slides in the fixed frame 203a. The inclined plate 203b is fixed to the end of the movable rod 202 and cooperates with the fastening plate 204. The two ends of the second spring 203c are respectively fixed to the inclined plate 203b and the fixed frame 203a.

[0050] The fixing frame 203a is used to fix the movable rod 202, and the inclined plate 203b is located above the fastening plate 204. The second spring 203c applies a force to the movable rod 202 to move in the direction of the inspection port S, making it more convenient to reset.

[0051] The guide member 205 includes a fixed block 205a, a fixed rod 205b and a third spring 205c. The fixed block 205a is fixed to the inner wall of the water collection pool 103 and is located above the fastening plate 204. The fixed rod 205b is fixed to the bottom of the fixed block 205a. The two ends of the third spring 205c are respectively fixed to the fixed block 205a and the fastening plate 204.

[0052] The fastening plate 204 is guided and limited by the fixing block 205a and the fixing rod 205b to prevent it from deflecting during the up and down movement. The third spring 205c applies an upward pulling force to the fastening plate 204, so that when the inclined plate 203b is separated from the fastening plate 204, the fastening plate 204 can move up and separate from the filter screen 107, thereby releasing the fixing effect on it.

[0053] When the filter 107 needs to be removed, the side door 201 is removed. At this time, the second spring 203c drives the movable rod 202 to move toward the inspection port S, so that the inclined plate 203b is separated from the fastening plate 204, and the fastening plate 204 can move up and separate from the filter 107, releasing the fixing effect on it. When installing, the side door 201 is fixed in the inspection port S, and the movable rod 202 is pushed inward by the side door 201. At this time, the inclined plate 203b slides on the inclined surface of the fastening plate 204, thereby driving the fastening plate 204 to move downward, applying pressure on the filter 107 to fix it.

[0054] The trigger member 302 includes a slider 302a, a limit block 302b, a first magnet 302c and a second magnet 302d. The slider 302a is fixed to the inner bottom of the trigger rod 301. Both sides of the connecting rod 106b are provided with inclined grooves K that cooperate with the slider 302a. The limit block 302b is fixed to the surface of the trigger rod 301 and is located in the water supply pipe 104. The first magnet 302c is fixed to the top of the trigger rod 301 and is located on the top of the receiving plate 108a. The second magnet 302d is fixed to the bottom of the filter screen 107.

[0055] When the slider 302a and the trigger rod 301 move upward, the slider 302a moves in the inclined groove K, thereby driving the connecting rod 106b to reset to the state where the blocking block 106c blocks the water supply hole P. The limit block 302b is used to limit the trigger rod 301 to prevent it from moving too much upward, causing the slider 302a to move above the inclined groove K and affecting its reset operation.

[0056] The first magnet 302c and the second magnet 302d attract each other. When the filter 107 is removed and moved upward, the second magnet 302d drives the first magnet 302c and the trigger rod 301 to move upward, so that the blocking block 106c is reset, preventing rainwater from carrying too many impurities into the water supply hole P before being filtered by the filter 107.

[0057] The trigger member 302 further includes a connecting plate 302e and a fourth spring 302f. The connecting plate 302e is fixed to the surface of the trigger rod 301. Two ends of the fourth spring 302f are respectively fixed to the receiving plate 108a and the connecting plate 302e.

[0058] An upward pulling force is applied to the trigger rod 301 through the connecting plate 302e and the fourth spring 302f to prevent the magnetism of the magnet from decreasing during long-term use and affecting the use of the device. The staff can inspect the magnet and the fourth spring 302f on time to ensure that at least one of the two can function.

[0059] The driving member 304 includes a support rod 304a, a fifth spring 304b and a fixed plate 304c. The support rod 304a is fixed to the top of the limit frame 303. Both ends of the fifth spring 304b are respectively fixed to the inner wall of the water supply pipe 104 and the limit frame 303. The fixed plate 304c is fixed to the surface of the support rod 304a.

[0060] The top end of the support rod 304a is located on one side of the receiving plate 108a. The setting of the fixing plate 304c can prevent the support rod 304a from moving too much upwards to affect its limiting effect on the fixing plate 106d.

[0061] When the filter 107 is removed, the limit frame 303 and the support rod 304a are driven to move upward by the fifth spring 304b. Because the slider 302a and the trigger rod 301 are resetting the connecting rod 106b and the fixed plate 106d during this process, when the fixed plate 106d is reset to the initial state, the limit frame 303 also moves upward and is clamped on the outer side of the fixed plate 106d, so as to fix the fixed plate 106d, and further prevent the water replenishment hole P from being accidentally opened. When the filter 107 is cleaned and installed on the receiving plate 108a, the trigger rod 301 and the support rod 304a are pushed downward by the gravity of the filter 107, so as to release the limiting effect on the fixed plate 106d, so that the water replenishment operation can be performed normally.

[0062] Example 3

[0063] Reference Figures 1 to 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0064] Specifically, the ground source heat pump heat exchange pipes 102 are evenly installed around the transmission tower foundation piles 101;

[0065] The highest point of the ground source heat pump heat exchange pipe 102 is connected to the water supply pipe 104 to continuously supply water to the inside thereof, and at the same time, the air discharge pipe 105 is connected to discharge the air inside thereof;

[0066] Rainwater is collected through the water collection tank 103, and the filtered rainwater is replenished into the ground source heat pump heat exchange pipe 102 through the water replenishment pipe 104;

[0067] When the filter 107 needs to be removed, the side door 201 is removed. At this time, the second spring 203c drives the movable rod 202 to move toward the inspection opening S, so that the inclined plate 203b is separated from the fastening plate 204, and the fastening plate 204 can move upward to separate from the filter 107, releasing the fixing effect on it. When installing, the side door 201 is fixed in the inspection opening S, and the movable rod 202 is pushed inward by the side door 201. At this time, the inclined plate 203b slides on the inclined surface of the fastening plate 204, thereby driving the fastening plate 204 to move downward, exerting pressure on the filter 107 to fix it;

[0068] At the same time, when the filter 107 is removed, the limit frame 303 and the support rod 304a are driven to move upward by the fifth spring 304b. Because the slider 302a and the trigger rod 301 are resetting the connecting rod 106b and the fixed plate 106d during this process, when the fixed plate 106d is reset to the initial state, the limit frame 303 also moves upward and is clamped on the outer side of the fixed plate 106d, so as to fix the fixed plate 106d, and further prevent the water replenishment hole P from being accidentally opened. When the filter 107 is cleaned and installed on the receiving plate 108a, the trigger rod 301 and the support rod 304a are pushed downward by the gravity of the filter 107, so as to release the limiting effect on the fixed plate 106d, so that it can perform the water replenishment operation normally.
