Description

Technical Field

[0001] This application relates to the technical field of liquefied gas storage, and in particular to a leveling structure for the inner wall of a storage tank. Background Art

[0002] A membrane storage tank is a storage tank for storing cryogenic liquefied gases, which is composed of a membrane insulation system and a prestressed concrete or steel outer tank, etc. Cryogenic liquefied gases are gases that are in a liquid state due to low temperature, such as liquid nitrogen, liquefied natural gas (LNG), cryogenic liquefied hydrocarbons or mixtures, and other similar media.

[0003] An LNG membrane storage tank is a tank structure for storing liquefied natural gas (LNG). With the increase in global natural gas consumption, as a new type of storage tank technology, LNG membrane storage tanks have broad application scenarios. The construction technical standards for LNG membrane storage tanks can adopt the design and construction requirements for onshore membrane tanks in the group standard of the China National Shipbuilding Industry Association (T / CANSI99 - 2022).

[0004] When the outer tank of the membrane storage tank uses a concrete outer tank, due to construction errors and other reasons, there will be local sunken concrete surface defects on the inner peripheral wall of the concrete outer tank; before installing the membrane insulation system, it is necessary to level the inner peripheral wall of the concrete outer tank to improve the flatness of the inner peripheral wall of the concrete outer tank and ensure the installation accuracy of the membrane insulation system.

[0005] In the prior art, a theoretical reference plane is established on the inner peripheral wall of the concrete outer tank, and then wedge blocks are used for installation adjustment; that is, the inner peripheral wall of the concrete outer tank is leveled by using wedge blocks so that the flatness of the concrete outer tank meets the design requirements.

[0006] However, the areas and shapes of the local grooves in the concrete outer tank are different, so the required wedge blocks for different leveling areas are also different; the staff needs to customize wedge blocks for the leveling areas of the concrete outer tank, and the whole construction process is complex, cumbersome and has a long construction period. Summary of the Invention

[0007] In order to facilitate the staff to level the storage tank and improve the leveling efficiency of the storage tank, this application provides a leveling structure for the inner wall of the storage tank.

[0008] A leveling structure for the inner wall of the storage tank provided by this application adopts the following technical solution:

[0009] A leveling structure for the inner wall of a storage tank. The storage tank includes a concrete outer tank and a thin-film insulation system. The thin-film insulation system is laid on the inner peripheral wall of the concrete outer tank, and there are concave areas on the inner peripheral wall of the concrete outer tank. It includes a surrounding component, a fixing component, and a traction component. The surrounding component includes a formwork. The shape of the formwork is adapted to the shape of the concrete outer tank. The formwork is used to cover the concave areas on the concrete outer tank. The formwork and the concrete outer tank enclose an accommodation chamber. The formwork is provided with a grouting hole for injecting slurry and a slurry outlet hole for the slurry to flow out. The slurry solidifies into a leveling piece in the accommodation chamber. The formwork includes a flexible layer and a rigid layer that are laminated and fixed. The flexible layer is abutted and fixed to the concrete outer tank. The traction component moves the surrounding component on the concrete outer tank so that the surrounding component covers the concave areas on the concrete outer tank. The fixing component is used to apply a force towards the concrete outer tank to the formwork to force the surrounding component to be abutted and fixed to the concrete outer tank.

[0010] By adopting the above technical solution, the traction component moves the surrounding component and the traction component to the concave area to be leveled. The fixing component applies a force towards the concrete outer tank to the formwork, so that the formwork fits the concrete outer tank and encloses an accommodation chamber with the concrete outer tank. Inject slurry into the accommodation chamber so that the slurry fills the accommodation chamber. Wait for the slurry to solidify and harden into a leveling piece, and the leveling piece fills the concave area of the concrete outer tank.

[0011] That is, the leveling structure is used to level the inner peripheral wall of the concrete outer tank. While improving the flatness of the inner peripheral wall of the concrete outer tank, it is convenient for the staff to construct, improves the leveling efficiency of the concrete outer tank, and shortens the construction period of leveling the concrete outer tank.

[0012] Optionally, the fixing component includes a first fixing component and a second fixing component. The first fixing component includes a first positioning wheel, a second positioning wheel, a fixing rope, and a fixing traction piece. Along the vertically upward direction, the first positioning wheel and the second positioning wheel are arranged on both sides of the concave area. The first positioning wheel and the second positioning wheel are fixedly connected to the concrete outer tank. The fixing rope is wound around the first positioning wheel and the second positioning wheel in sequence. The fixing traction piece pulls the fixing rope to be taut. The second fixing component is fixedly arranged on the side of the formwork away from the concrete outer tank. The fixing rope passes through the second fixing component, and the fixing rope is taut to apply a force towards the concrete outer tank to the second fixing component.

[0013] By adopting the above technical solution, when the traction component moves the surrounding component to the concave area of the concrete outer tank, the fixing driving piece in the first fixing component pulls the fixing rope, and the fixing rope applies a force towards the concrete outer tank to the formwork through the second fixing component, so that the formwork is temporarily fixed on the concrete outer tank, thereby facilitating the staff to install the leveling structure and improving the leveling efficiency of the concrete outer tank.

[0014] Optionally, the second fixing component includes a support sleeve and support legs. There are a plurality of the support legs, and the plurality of support legs are arranged around the support sleeve. One end of the support leg is fixedly connected to the support sleeve, and the other end of the support leg is fixedly connected to the formwork.

[0015] By adopting the above technical solution, when the first fixing component applies a force to the formwork, the plurality of support legs disperse the force to several positions of the formwork, so as to improve the sealing performance of the formwork in contact with the concrete outer tank.

[0016] Optionally, the second fixing component further includes a plugging rod, a spring member and a third positioning wheel; the plugging rod is plugged into the support sleeve. Along the direction close to the formwork, a first limiting ring and a second limiting ring are arranged on the outer periphery of the support sleeve. The first limiting ring and the second limiting ring are arranged on both sides of the support sleeve. The spring member is arranged between the support sleeve and the first limiting ring. The third positioning wheel is fixedly arranged on the side of the support sleeve away from the formwork; the fixing rope is wound around the third positioning wheel. When the fixing rope applies a force to the third positioning wheel, the plugging rod moves towards the formwork, and the plugging rod applies a force to the support sleeve through the spring member.

[0017] By adopting the above technical solution, when the first fixing component applies a force to the second fixing component, due to the existence of the spring member, the force received by the second fixing component decreases, that is, the force applied by the second fixing component to the formwork also gradually increases. Thus, when the staff controls the fixing driving member to pull the fixing rope to apply a force to the second fixing component, the second fixing component has a larger winding amount space, which is convenient for the staff to operate; at the same time, the second fixing component slowly applies a force to the formwork, which is convenient for the connection between the formwork and the concrete outer tank.

[0018] When it comes to the formwork removal stage, the fixing driving member unwinds the rope, and the second fixing component loses the external force. The spring member forces the plugging rod to move away from the formwork, so that the plugging rod is separated from the anchoring sleeve, which is convenient for the staff to remove the formwork subsequently and improves the construction efficiency.

[0019] Optionally, it further includes an anchoring component and a connecting component. The anchoring component includes an anchoring bolt, an anchoring sleeve and an elastic gasket. The anchoring bolt is arranged in the concave area of the concrete outer tank, and the anchoring bolt is fixedly connected to the concrete outer tank. The anchoring sleeve is threadedly connected to the anchoring bolt. The elastic gasket is fixedly arranged at one end of the anchoring sleeve away from the anchoring bolt, and the elastic gasket abuts against the formwork; the anchoring sleeve is detachably connected to the formwork through the connecting component.

[0020] By adopting the above technical solution, through the connection between the anchoring component and the connecting component, the concrete outer tank has a fixing effect on the formwork, so as to improve the connection stability between the concrete outer tank and the formwork, facilitate the pouring of slurry into the sunken area, and improve the quality of the leveling piece.

[0021] Optionally, the formwork is provided with an installation hole for installing the connecting component, and the connecting component is fixedly connected to the formwork; the connecting component includes a connecting sleeve, an elastic rod and a spike part, the connecting sleeve is fixedly arranged in the installation hole, the first end of the elastic rod is fixedly connected to the connecting sleeve, the second end of the elastic rod is inserted into the anchoring sleeve, the distance from the second end of the elastic rod to the central axis of the connecting sleeve is less than the inner diameter of the connecting sleeve, and the spike part is fixedly arranged on the outer periphery of the elastic rod; when the fixing rope applies a force to the inserting rod, the inserting rod penetrates through the connecting sleeve, and the inserting rod forces the elastic rod to expand outwards, and the spike part is engaged and fixed with the anchoring sleeve under the action of the inserting rod.

[0022] By adopting the above technical solution, when the first fixing component applies a force to the second fixing component, the second fixing component forces the formwork to be in close contact with the concrete outer tank; at the same time, the inserting rod is inserted into the anchoring sleeve, and the inserting rod forces the elastic rod to expand outwards, so that the spike part on the elastic rod is engaged and fixed with the anchoring sleeve; to improve the connection strength and connection stability between the anchoring component and the formwork.

[0023] Optionally, the anchoring sleeve includes a metal sleeve and a contact sleeve, the contact sleeve is fixedly arranged in the metal sleeve; one end of the metal sleeve is threadedly connected to the anchoring bolt, and a limiting convex ring is arranged at the other end of the metal sleeve, and the limiting convex ring is arranged on the inner wall of the metal sleeve; the contact sleeve abuts against the limiting convex ring, the stiffness of the contact sleeve is less than the stiffness of the spike part, and the spike part is used for inserting into the contact sleeve.

[0024] By adopting the above technical solution, by setting the anchoring sleeve as a metal sleeve and a contact sleeve, the metal sleeve has a high connection strength with the anchoring bolt; and the stiffness of the contact sleeve is less than the stiffness of the spike part, so as to facilitate the spike part to be inserted into the contact sleeve, facilitate the construction of the staff, and improve the connection strength and connection stability between the anchoring component and the formwork.

[0025] Optionally, a plurality of elastic rods are provided, and the plurality of elastic rods are arranged around the connecting sleeve; the connecting component further includes an elastic membrane, the elastic membrane is arranged at one end of the elastic rod away from the connecting sleeve, the elastic membrane is fixedly connected to the elastic rod, and the elastic membrane is used for forcing the elastic rods to approach each other.

[0026] By adopting the above technical solution, when the insertion rod forces the elastic rod to expand outward, the elastic rod pulls the elastic mold to expand and deform; and when the insertion rod is separated from the anchoring sleeve, the elastic mold forces the elastic rods to approach each other, so that the spike part is separated from the abutting sleeve, facilitating the separation of the mold from the concrete outer tank, facilitating the operation of the staff, and improving the leveling efficiency of the concrete outer tank.

[0027] Optionally, the traction assembly includes a traction guide wheel, a traction rope, and a traction driving member; the traction guide wheel is fixedly arranged on the concrete outer tank, and the elevation of the traction guide wheel is higher than the elevation of the sunken area. One end of the traction rope is connected to the traction driving member, and the other end of the traction rope is wound around the traction guide wheel and fixedly connected to the template; at least two groups of the traction assemblies are arranged, and along the circumferential direction of the concrete outer tank, at least two groups of traction assemblies are arranged on both sides of the sunken area.

[0028] By adopting the above technical solution, when there are multiple adjacent sunken areas on the concrete outer tank, by arranging two groups of traction assemblies in the concrete circumferential direction, the staff can adjust the working conditions of the two groups of traction assemblies, move the template to different sunken areas, simplify the leveling construction steps of the staff, and improve the leveling efficiency of the concrete outer tank.

[0029] Optionally, at least two groups of the first fixing assemblies are arranged, and the number of the third positioning wheels is the same as that of the first fixing assemblies; along the circumferential direction of the concrete outer tank, at least two groups of the second fixing assemblies are arranged on both sides of the sunken area.

[0030] By adopting the above technical solution, along the direction of the concrete outer tank, the second fixing assemblies are arranged on both sides of the sunken area; thus, when the sunken area is not on the connection line between the first positioning wheel and the second positioning wheel, the horizontal forces exerted by multiple groups of the first fixing assemblies on the second fixing assemblies can cancel each other out, so that multiple groups of the first fixing assemblies jointly exert a force on the second fixing assembly towards the concrete outer tank.

[0031] That is, by arranging multiple groups of the first fixing assemblies, the first fixing assemblies have a fixing effect on the templates at different positions; thus, the application range of the first fixing assemblies is improved, the leveling steps are simplified, and the leveling efficiency of the concrete outer tank is improved.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. Using the leveling structure to level the inner peripheral wall of the concrete outer tank, while improving the flatness of the inner peripheral wall of the concrete outer tank, it facilitates the construction of the staff, improves the leveling efficiency of the concrete outer pipe tank, and shortens the construction period of leveling the concrete outer tank;

[0034] 2. When the first fixing component exerts a force on the second fixing component, due to the presence of the spring member, the force received by the second fixing component decreases, that is, the force exerted by the second fixing component on the template also gradually increases. Thus, when the staff controls the fixing driving member to pull the fixing rope to exert a force on the second fixing component, the second fixing component has a larger winding space, which is convenient for the staff to operate; at the same time, the second fixing component slowly exerts a force on the template, which is convenient for the connection between the template and the concrete outer tank.

[0035] 3. When the first fixing component exerts a force on the second fixing component, the second fixing component forces the template to be in close contact with the concrete outer tank; at the same time, the insertion rod is inserted into the anchoring sleeve, and the insertion rod forces the elastic rod to expand outward, so that the spiked portion on the elastic rod is engaged and fixed with the anchoring sleeve; to improve the connection strength and connection stability between the anchoring component and the template.

Refer to Figure 1 , the storage tank is a thin-film storage tank, and the storage tank is arranged on a foundation 8. The storage tank includes a concrete outer tank 1 and a thin-film insulation system 2, and the thin-film insulation system 2 is laid on the inner peripheral wall of the concrete outer tank 1. The thin-film insulation system 2 is composed of a main shielding film 21, a secondary shielding film 22, a main insulation module 23 and a secondary insulation module 24. The thin-film storage tank is a prior art, and the thin-film storage tank is not the main inventive point of the present application; the specific structure of the thin-film storage tank will not be described in detail in this embodiment.

[0049] Refer to Figure 1 and Figure 2 , in this embodiment, the concrete outer tank 1 is in the shape of a 56-sided polygon; in the prior art, there are many practical cases of the 56-sided concrete outer tank 1. One side of the concrete outer tank 1 is taken as an example in this embodiment for explanation.

[0050] Refer to Figure 1 and Figure 2In the vertical direction, there are several different concave areas 11 on the inner wall of the concrete outer tank 1, which are concrete surface defects caused by construction errors. Before laying the film insulation system 2, it is necessary to level the concave areas 11 on the concrete outer tank 1 to improve the flatness of the concrete outer tank 1 and improve the installation accuracy of the film insulation system 2.

[0051] Reference Figure 3 The tank inner wall leveling structure includes a traction assembly 3, a enclosure assembly 4 and a fixing assembly 5. The traction assembly 3 carries the enclosure assembly 4 to move on the concrete outer tank 1 so that the enclosure assembly 4 covers the recessed area 11 on the concrete outer tank 1; the fixing assembly 5 is used to apply a force toward the concrete outer tank 1 to the template 41 to force the enclosure assembly 4 to abut and fix with the concrete outer tank 1.

[0052] Reference Figure 3 and Figure 4 The traction assembly 3 includes a traction guide wheel 31, a traction rope 32 and a traction drive 33; the traction guide wheel 31 is fixed to the concrete outer tank 1, and the elevation of the traction guide wheel 31 is greater than the elevation of the position of the recessed area 11, one end of the traction rope 32 is connected to the traction drive 33, and the other end of the traction rope 32 is wound around the traction guide wheel 31 and fixedly connected to the template 41. In this embodiment, the traction drive 33 is a winch.

[0053] Reference Figure 4 and Figure 5 The enclosure assembly 4 includes a template 41 and a sealing ring 42. The shape of the template 41 is adapted to the shape of the concrete outer tank 1. The template 41 is used to cover the recessed area 11 on the concrete outer tank 1. The template 41 and the concrete outer tank 1 are surrounded by a receiving chamber. The template 41 is provided with a grouting hole 411 for slurry injection, and the template 41 is provided with a slurry outlet hole 412 for slurry to flow out. The slurry solidifies into a leveling member 10 in the receiving chamber. The outer periphery of the template 41 is provided with an annular groove 416, and the sealing ring 42 is arranged in the annular groove 416; so that when the template 41 abuts against the concrete outer tank 1, the risk of slurry outflow can be further reduced. The sealing ring 42 can be a solid rubber ring or a silicone ring, or a hollow rubber ring or a silicone ring. In this embodiment, the sealing ring 42 is a solid rubber ring. In this embodiment, the grouting hole 411 of the template 41 is connected to a grouting pipe, and the grouting hole 412 of the template 41 is connected to a grouting pipe; so that the staff can inject grout into the receiving chamber. The grout can be self-compacting concrete grout, weighing resin cement, etc., and a release agent is brushed on the template 41 to facilitate demolding. In this embodiment, the grout uses self-compacting concrete grout.

[0054] The template 41 includes a flexural layer 413 and a rigid layer 414 that are stacked and fixed. The flexural layer 413 is fixedly abutted against the concrete outer tank 1.

[0055] Referring to Figure 3 and Figure 4 , the fixing assembly 5 includes a first fixing assembly 51 and a second fixing assembly 52.

[0056] Referring to Figure 3 and Figure 4 , the first fixing assembly 51 includes a first positioning wheel 511, a second positioning wheel 512, a fixing rope 513, and a fixing traction member 514. Along the vertically upward direction, the first positioning wheel 511 and the second positioning wheel 512 are arranged on both sides of the recessed area 11. The first positioning wheel 511 and the second positioning wheel 512 are fixedly connected to the concrete outer tank 1; one end of the fixing rope 513 is fixedly connected to the fixing traction member 514. After the fixing rope 513 is sequentially wound around the first positioning wheel 511 and the second positioning wheel 512, the other end of the fixing rope 513 is fixedly connected to the foundation 8 through a fixing ring 9. The fixing traction member 514 is a winch, and the fixing traction member 514 pulls the fixing rope 513 to be taut.

[0057] Referring to Figure 3 and Figure 4 , the second fixing assembly 52 is fixedly arranged on the side of the formwork 41 away from the concrete outer tank 1, and the fixing rope 513 passes through the second fixing assembly 52. When the traction assembly 3 moves the enclosure assembly 4 to the recessed area 11 of the concrete outer tank 1, the fixing rope 513 is pulled by the fixing driving member in the first fixing assembly 51, and the fixing rope 513 is taut to apply a force towards the concrete outer tank 1 to the second fixing assembly 52.

[0058] Referring to Figure 3 and Figure 4 , in this embodiment, the second fixing assembly 52 includes a support sleeve 521, support legs 522, insertion rods 523, spring members 524, and a third positioning wheel 525. A plurality of support legs 522 are provided. The plurality of support legs 522 are arranged around the support sleeve 521. One end of the support leg 522 is fixedly connected to the support sleeve 521, and the other end of the support leg 522 is fixedly connected to the formwork 41. When the first fixing assembly 51 applies a force to the formwork 41, the plurality of support legs 522 disperse the force to several positions on the formwork 41 to improve the sealing performance of the formwork 41 abutting against the concrete outer tank 1.

[0059] Referring to Figure 4, the insertion rod 523 is inserted into the support sleeve 521. Along the direction close to the template 41, a first limiting ring 5231 and a second limiting ring 5232 are provided on the outer periphery of the support sleeve 521. The first limiting ring 5231 and the second limiting ring are arranged on both sides of the support sleeve 521. The spring member 524 is arranged between the support sleeve 521 and the first limiting ring 5231. The third positioning wheel 525 is fixedly arranged on the side of the support sleeve 521 away from the template 41. The fixing rope 513 is wound around the third positioning wheel 525. When the fixing rope 513 applies a force to the third positioning wheel 525, the insertion rod 523 moves towards the template 41, and the insertion rod 523 applies a force to the support sleeve 521 through the spring member 524.

[0060] Referring to Figure 3 and Figure 4 , when the first fixing component 51 applies a force to the second fixing component 52, due to the existence of the spring member 524, the force received by the second fixing component 52 decreases, that is, the force applied by the second fixing component 52 to the template 41 also gradually increases. Thus, when the staff controls the fixing driving member to pull the fixing rope 513 to apply a force to the second fixing component 52, the second fixing component 52 has a larger winding amount space, which is convenient for the staff to operate; at the same time, the second fixing component 52 slowly applies a force to the template 41, which is convenient for the template 41 to be in sealed contact with the concrete outer tank 1.

[0061] The implementation principle of a leveling structure for the inner wall of a storage tank in an embodiment of the present application is as follows:

[0062] Referring to Figure 3 and Figure 4 , the traction assembly 3 moves the enclosure assembly 4 and the traction assembly 3 to the sunken area 11 to be leveled. The fixing assembly 5 applies a force towards the concrete outer tank 1 to the template 41, so that the template 41 fits against the concrete outer tank 1, and an accommodation chamber is formed with the concrete outer tank 1; slurry is injected into the accommodation chamber, so that the slurry fills the accommodation chamber. When the slurry solidifies and hardens into a leveling member 10, the leveling member 10 fills the sunken area 11 of the concrete outer tank 1.

[0063] That is, the leveling structure is used to level the inner peripheral wall of the concrete outer tank 1. While improving the flatness of the inner peripheral wall of the concrete outer tank 1, it is convenient for the staff to construct, improves the leveling efficiency of the concrete outer pipe tank, and shortens the construction period of leveling the concrete outer tank 1.

When the fixing rope 513 applies a force to the insertion rod 523, the insertion rod 523 penetrates through the connection sleeve 71, and the insertion rod 523 forces the elastic rod 72 to expand outwards. The stiffness of the abutting sleeve 622 is less than the stiffness of the spike portion 73.

The elastic membrane 74 is arranged at one end of the elastic rod 72 far from the connection sleeve 71, and the elastic membrane 74 is fixedly connected to the elastic rod 72. The elastic membrane 74 is used to force the elastic rods 72 to approach each other. The alignment work of the anchoring sleeve 62 and the connection sleeve 71 can be assisted by using unmanned aerial vehicle technology.

[0071] Referring to Figure 7 and Figure 8 , by setting the anchoring sleeve 62 as a metal sleeve 621 and an abutting sleeve 622, the metal sleeve 621 has a high connection strength with the anchoring bolt 61; while the stiffness of the abutting sleeve 622 is less than the stiffness of the spike portion 73, so that the spike portion 73 can be inserted into the abutting sleeve 622, which is convenient for the staff to construct and improves the connection strength and connection stability between the anchoring component 6 and the template 41.

[0072] The implementation principle of an inner wall leveling structure of a storage tank in an embodiment of the present application is as follows:

[0073] Referring to Figures 6 to 8 , when the first fixing component 51 applies a force to the second fixing component 52, the second fixing component 52 forces the template 41 to closely abut against the concrete outer tank 1; at the same time, the insertion rod 523 is inserted into the anchoring sleeve 62, and the insertion rod 523 forces the elastic rod 72 to expand outwards, so that the spike portion 73 on the elastic rod 72 is engaged and fixed with the anchoring sleeve 62; to improve the connection strength and connection stability between the anchoring component 6 and the template 41.

[0074] Referring to Figures 6 to 8, when it comes to the form removal stage, the fixed driving member unwinds the roll, and the second fixing assembly 52 loses the external force. The spring member 524 forces the insertion rod 523 to move away from the formwork 41, causing the insertion rod 523 to separate from the anchoring sleeve 62. After the insertion rod 523 disengages from the anchoring sleeve 62, the elastic mold forces the elastic rods 72 to approach each other, so that the spike portion 73 separates from the abutting sleeve 622, facilitating the separation of the mold from the concrete outer tank 1, facilitating the operation of the staff, and improving the leveling efficiency of the concrete outer tank 1.

[0075] Refer to Figures 6 to 8 , that is, through the connection of the anchoring assembly 6 and the connecting assembly 7, the concrete outer tank 1 has a fixing effect on the formwork 41, so as to improve the connection stability between the concrete outer tank 1 and the formwork 41, facilitate pouring slurry into the concave area 11, and improve the quality of the leveling member 10.

[0076] Embodiment 3

[0077] The difference between this Embodiment 3 and Embodiment 1 is that:

[0078] In this embodiment, in the vertical direction, the concave areas 11 on the concrete outer tank 1 are arranged staggeredly.

[0079] Refer to Figure 9 , the traction assembly 3 is provided with at least two groups. Along the circumferential direction of the concrete outer tank 1, at least two groups of traction assemblies 3 are arranged on both sides of the concave area 11. The first fixing assembly 51 is provided with at least two groups, and the number of the third positioning wheels 525 is the same as that of the first fixing assembly 51; along the circumferential direction of the concrete outer tank 1, at least two groups of second fixing assemblies 52 are arranged on both sides of the concave area 11.

[0080] Refer to Figure 9 , in this embodiment, there are two groups of traction assemblies 3, and the two groups of traction assemblies 3 are arranged on both sides of the concave area 11. There are two groups of first fixing assemblies 51, and the two groups of first fixing assemblies 51 are arranged on both sides of the concave area 11.

[0081] The implementation principle of an inner wall leveling structure of a storage tank in an embodiment of the present application is as follows:

[0082] Refer to Figure 9 , when there are multiple adjacent concave areas 11 on the concrete outer tank 1, by providing two groups of traction assemblies 3 in the concrete circumferential direction, the staff can adjust the working conditions of the two groups of traction assemblies 3, move the formwork 41 to different concave areas 11, simplify the leveling construction steps of the staff, and improve the leveling efficiency of the concrete outer tank 1.

[0083] Refer to Figure 9, along the direction of the concrete outer tank 1, second fixing components 52 are arranged on both sides of the recessed area 11; thus, when the recessed area 11 is not on the connection line between the first positioning wheel 511 and the second positioning wheel 512, the horizontal acting forces applied by multiple groups of first fixing components 51 to the second fixing components 52 can cancel each other out, so that multiple groups of first fixing components 51 jointly apply an acting force towards the concrete outer tank 1 to the second fixing components 52.

[0084] That is, by arranging multiple groups of first fixing components 51, the first fixing components 51 have a fixing effect on the formworks 41 at different positions; thus, the application range of the first fixing components 51 is improved, the leveling steps are simplified, and the leveling efficiency of the concrete outer tank 1 is improved.

[0085] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
