Description

Technical Field

[0001] The invention relates to the technical field of filtering equipment, and in particular to a large-scale flat-bottom tank concrete leveling layer construction device and method. Background Art

[0002] At present, large flat-bottomed storage tanks for storing low-temperature liquefied media such as liquefied natural gas or liquid ethylene are increasingly used. With the development of large-scale storage tanks, the diameter of the storage tanks is getting larger and larger, and the construction area of ​​the bottom insulation layer is also greatly increased, and the requirements for the construction of the bottom insulation layer are also getting higher and higher. The bottom insulation layer of the storage tank is composed of concrete leveling layer, foam glass bricks, asphalt felt and other materials, and the materials are assembled on site.

[0003] In traditional technology, concrete leveling layer construction mostly uses concrete pump trucks to pump concrete into the storage tank through a retractable and flexural distribution boom. Due to the small size of the temporary door of the storage tank, the length of the concrete pump truck's distribution boom is too long, and the concrete pump truck's site is limited, most concrete pump trucks can only pump concrete to the area from the center of the storage tank to the temporary door. Workers then use small transport bucket trucks to transfer the concrete to the surrounding areas of the tank and then lay the concrete flat. Due to the large-scale development of storage tanks, the workload of concrete transportation is increasing. When small transport bucket trucks transport concrete to the surrounding areas of the storage tank, the wheels of the small transport bucket trucks roll back and forth on the bottom insulation layer, which may cause damage to the foam glass bricks, and the displacement of the glass bricks will cause the gaps between the foam glass bricks to be too large, affecting the effect of the bottom insulation layer. Therefore, there is an urgent need for a large flat-bottomed tank concrete leveling layer construction device and method that reduces labor intensity and avoids damage to the bottom insulation layer. Summary of the invention

[0012] In one embodiment, the input pipe includes a plurality of first straight pipe sections, and a connecting clamp connecting two adjacent first straight pipe sections;

[0013] Both ends of each first straight pipe section are respectively provided with connecting rings, and the connecting clamp can be arranged on the outer circumference of the two connecting rings of two adjacent first straight pipe sections so that the two adjacent first straight pipe sections are fixedly connected.

[0027] When the target area is poured, the length of the input pipe is adjusted so that the output pipe can pour concrete for the next area in the X-axis direction.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0048] The large flat-bottom tank concrete leveling layer construction device and method of the present invention are mainly used for the concrete leveling layer construction of the bottom insulation layer of a large flat-bottom low-temperature storage tank. Figure 1 As shown, a multi-layered insulation layer 40 is usually provided at the bottom of the large flat-bottomed cryogenic storage tank 10. For example, the insulation layer 40 provided on the foundation pedestal 30 of the storage tank 10 may include a concrete leveling layer 41, a foam glass brick layer 42, a concrete leveling layer 43, a concrete leveling layer 44, a foam glass brick layer 45, and a concrete leveling layer 46 stacked in sequence.

[0049] The large flat-bottom tank concrete leveling layer construction device and method proposed in the present invention are used to construct each concrete leveling layer 41, 43, 44, 46.

[0050] See also Figure 1 and Figure 2As shown, the large flat-bottom tank concrete leveling layer construction device (hereinafter referred to as the construction device) of the embodiment of the present invention includes an input pipe 100, a first connecting pipe 200, a second connecting pipe 300 and an output pipe 400. The input pipe 100 has a first end and a second end opposite to each other, the first end is used to communicate with the concrete supply equipment outside the storage tank 10, and the second end extends along the X-axis direction to the target area in the storage tank 10, and the length of the input pipe 100 is adjustable.

[0051] One end of the first connecting pipe 200 is connected to the second end through an elbow, and the first connecting pipe 200 extends at an angle to the X-axis in the XY plane. One end of the second connecting pipe 300 is connected to the other end of the first connecting pipe 200 through an elbow, and the second connecting pipe 300 extends upward at an angle to the X-axis in the XZ plane. One end of the output pipe 400 is connected to the other end of the second connecting pipe 300 through an elbow, and the output pipe 400 is arranged in the horizontal direction, and the output pipe 400 can make a circular motion around the Z axis, and the other end of the output pipe 400 is used to output concrete downward.

[0052] It should be noted that during the construction of the storage tank 10, the temporary door 20 is a very important component of the construction process of the storage tank 10, and plays a vital role in the subsequent cold preservation in the tank, installation of the inner tank, and construction of the pipeline in the tank. Among them, the cold preservation construction in the tank includes the construction of the insulation layer 40 at the bottom of the storage tank 10. That is, the construction of each concrete leveling layer in the insulation layer 40 is carried out through the temporary door 20.

[0053] It should be noted that see Figure 1 and Figure 2 As shown, in an embodiment of the present application, the X-axis direction can be a horizontal axis direction parallel to a line connecting the center of the bottom edge of the temporary door 20 and the center of the bottom surface of the storage tank 10 .

[0054] like Figure 1 and Figure 2 As shown, the input pipe 100 is a hard pipe arranged along the X-axis direction, which is mainly used to transport concrete outside the storage tank 10 to the target area inside the storage tank 10 through the temporary door 20. The first end of the input pipe 100 can be connected to the discharge pipe of the concrete ground pump equipment. The second end of the input pipe 100 can extend into the inner area of ​​the tank wall opposite to the temporary door 20 in the storage tank 10.

[0055] Preferably, the axis of the input pipe 100 intersects with the central axis of the storage tank 10. Thus, the input pipe 100 can extend along the longest path into the inner area of ​​the tank wall opposite to the temporary door 20. Therefore, the concrete can be transported to the innermost position of the tank through the input pipe 100, so that when pouring concrete, the construction can be carried out step by step from the innermost side of the tank to the outside, ensuring the continuity of the construction and avoiding the reciprocating construction inside and outside the tank.

[0056] In the present application, the length of the input pipe 100 is adjustable, so that the construction personnel can change the length of the input pipe 100 as needed to achieve the purpose of gradually pouring the tank from the innermost side to the outside.

[0057] See also Figure 1 For example, the input pipe 100 includes a plurality of first straight pipe sections 110 and a connecting clamp 120 connecting two adjacent first straight pipe sections 110. Each first straight pipe section 110 may be a carbon steel pipe. The connecting clamp 120 may be a steel clamp. The connecting clamp 120 may be used to clamp and fix two adjacent first straight pipe sections 110, so as to achieve the purpose of quick disassembly and assembly, thereby facilitating the adjustment of the length of the input pipe 100.

[0058] More specifically, both ends of each first straight pipe section 110 may be provided with a connecting ring, and the outer circumference of the connecting ring matches the inner groove of the connecting clamp 120. The connecting clamp 120 can be arranged on the outer circumference of the two connecting rings of two adjacent first straight pipe sections 110, so that the two adjacent first straight pipe sections 110 are fixedly connected. In this embodiment, by connecting the connecting clamp 120 and the end of each first straight pipe section 110, a quick-release fixed connection of multiple first straight pipe sections 110 can be achieved, so that it is convenient for construction personnel to quickly adjust the length of the input pipe 100 as needed, which is conducive to improving the convenience of construction and accelerating the construction progress.

[0059] In other embodiments, a connecting flange may also be provided at the end of each first straight pipe section 110 , and the connecting flanges of two adjacent first straight pipe sections 110 may be connected by bolts to achieve a quick-release fixed connection.

[0060] See also Figure 1 In one embodiment, the construction device further includes a plurality of support brackets 700, which are arranged at intervals along the length direction of the input pipe 100, and the plurality of support brackets 700 are used to jointly support the input pipe 100. For example, the support bracket 700 may be a structure roughly in the shape of a "door" welded by angle steel and steel plate. The input pipe 100 may be supported and placed on the top of the plurality of support brackets 700 to avoid collapse due to the excessive length of the input pipe 100. In addition, by supporting and placing the input pipe 100 with the plurality of support brackets 700, the input pipe 100 may be kept flush with the discharge pipe of the concrete ground pump equipment, thereby ensuring smooth transportation of concrete.

[0061] For ease of explanation, it is now stipulated that the elbow connecting the input pipe 100 and the first connecting pipe 200 is called the first elbow 51, the elbow connecting the first connecting pipe 200 and the second connecting pipe 300 is called the second elbow 52, ​​and the elbow connecting the second connecting pipe 300 and the output pipe 400 is called the third elbow 53.

[0062] like Figure 2 As shown, one end of the first connecting pipe 200 is connected to the second end of the input pipe 100 through the first elbow 51 , and the other end is connected to the second connecting pipe 300 through the second elbow 52 .

[0063] The first elbow 51 may be an L-shaped elbow or a V-shaped elbow, etc., which is used to change the direction of the first connecting pipe 200. For example, the first connecting pipe 200 may be a hard pipe extending and arranged at an angle to the X axis in the XY plane. The first connecting pipe 200 is mainly used to transport concrete to one side of the input pipe 100 for pouring. For example, Figure 2 As shown, the first connecting pipe 200 can be arranged to extend along the Y-axis direction, and it is at a right angle to the input pipe 100. Alternatively, the first connecting pipe 200 can also be arranged at an angle of 120° with the input pipe 100. In other words, the first connecting pipe 200 can be arranged to extend horizontally along the Y-axis direction, but the angle between it and the input pipe 100 may not be a right angle. The angle between the first connecting pipe 200 and the input pipe 100 can also be arranged at an acute angle or an obtuse angle, as long as the purpose of conveying concrete to one side of the input pipe 100 for pouring can be achieved.

[0064] It should be noted that, during construction, the first connecting pipe 200 can be arranged on either side of the input pipe 100 as needed to cast the side area of ​​the input pipe 100 .

[0065] In other embodiments, the construction device may also be equipped with two first connecting pipes 200. At the same time, the first elbow 51 is a T-shaped three-way elbow, so as to achieve the purpose of pouring both sides of the input pipe 100 at the same time.

[0066] In one embodiment, the input pipe 100 and the first connecting pipe 200 are connected in a quick-release manner. That is, the input pipe 100 and the first elbow 51 are connected in a quick-release manner, and the first elbow 51 and the first connecting pipe 200 are connected in a quick-release manner. For example, the end of the input pipe 100 and the end of the first elbow 51 can be fastened and fixed by a clamp. The end of the first elbow 51 and the end of the first connecting pipe 200 can also be fastened and fixed by a clamp.

[0067] See also Figure 1 In one embodiment, the length of the first connecting pipe 200 is adjustable, so that the construction personnel can change the length of the first connecting pipe 200 as needed to achieve the purpose of pouring concrete in the area far away from the side of the input pipe 100.

[0068] For example, the first connecting pipe 200 may include a plurality of second straight pipe sections 210, wherein each second straight pipe section 210 may be a carbon steel pipe. Any two adjacent second straight pipe sections 210 are detachably fixedly connected. For example, the opposite ends of two adjacent second straight pipe sections 210 may be fastened and fixed by clamps.

[0069] Of course, in other embodiments, the first connecting pipe 200 may also be a straight pipe with a fixed length, and its length can be set as needed.

[0070] like Figure 1 As shown, one end of the second connecting pipe 300 is connected to the first connecting pipe 200 through the second elbow 52, ​​and the other end is connected to the output pipe 400 through the third elbow 53. Among them, the second elbow 52 can be an L-shaped elbow or a V-shaped elbow, etc., which is used to change the direction of the second connecting pipe 300. For example, the second connecting pipe 300 can be a hard pipe that is angled with the X axis in the XZ plane and extends upward. The second connecting pipe 300 is mainly used to lift concrete to a certain height for pouring. Among them, the second connecting pipe 300 can be a carbon steel pipe.

[0071] For example, Figure 1 As shown, the second connecting pipe 300 can be arranged to extend upward along the Z-axis direction, and it is at right angles to the first connecting pipe 200 and the input pipe 100. Alternatively, the second connecting pipe 300 can also be arranged at an angle of 100° with the first connecting pipe 200. In other words, the second connecting pipe 300 can generally be arranged to extend upward along the Z-axis direction, but the angle between it and the first connecting pipe 200 may not be a right angle. The angle between the second connecting pipe 300 and the first connecting pipe 200 can also be arranged at an acute angle or an obtuse angle, as long as the purpose of lifting the concrete to a certain height can be achieved.

[0072] In one embodiment, the first connecting tube 200 and the second connecting tube 300 are connected in a quick-release manner. That is, the first connecting tube 200 and the second elbow 52 are connected in a quick-release manner, and the second elbow 52 and the second connecting tube 300 are connected in a quick-release manner. For example, the end of the first connecting tube 200 and the end of the second elbow 52 can be fastened and fixed by a clamp. The end of the second elbow 52 and the end of the second connecting tube 300 can also be fastened and fixed by a clamp.

[0073] It is understandable that the second connecting pipe 300 can be a straight pipe of fixed length, and its length can be set as required. Alternatively, the second connecting pipe 300 can also be assembled from a plurality of straight pipe sections.

[0074] See also Figure 1 and Figure 2In one embodiment, the construction device further includes a support assembly 600, and the support assembly 600 is arranged corresponding to the second connecting pipe 300. The support assembly 600 is used to support the second connecting pipe 300 so that the second connecting pipe 300 can be kept extending upward. Therefore, by setting the support assembly 600, the fixed state of the second connecting pipe 300 extending upward can be ensured, and the second connecting pipe 300 can be ensured to stably transport concrete, thereby improving the reliability of the construction device. In the following embodiments, the specific structure of the support assembly 600 is described by taking the second connecting pipe 300 extending vertically upward as an example.

[0075] like Figure 2 As shown, in one embodiment, the support assembly 600 may include a support cylinder 610, the axial direction of the support cylinder 610 is arranged along the Z-axis direction, and the support cylinder 610 is sleeved outside the second connecting tube 300. For example, the support cylinder 610 includes a first curved plate and a second curved plate that are relatively connected. Among them, the surface of the first curved plate relative to the second curved plate is a curved surface that matches the outer peripheral surface of the second connecting tube 300. The surface of the second curved plate relative to the first curved plate is a curved surface that matches the outer peripheral surface of the second connecting tube 300. Therefore, when the first curved plate and the second curved plate are relatively connected, the two can effectively limit and fix the second connecting tube 300.

[0076] The first curved plate and the second curved plate can be connected relative to each other in the following manner: one side of the first curved plate is hinged to one side of the second curved plate. For example, one side of the first curved plate and one side of the second curved plate can be hinged to each other via a hinge.

[0077] The other side of the first curved plate is detachably connected to the other side of the second curved plate. For example, the other side of the first curved plate and the other side of the second curved plate may be provided with lugs, respectively, and the two lugs are provided with connection holes. By passing fasteners such as bolts through the connection holes on the two lugs, the other side of the first curved plate and the other side of the second curved plate can be detachably fixedly connected.

[0078] In this embodiment, by hingedly connecting one side of the first arc plate to one side of the second arc plate, the other side of the first arc plate is detachably connected to the other side of the second arc plate, so that the support tube 610 can be quickly fixed on the periphery of the second connecting tube 300 and is easy to disassemble, thereby facilitating operation by construction personnel.

[0079] like Figure 2As shown, the support assembly 600 may include a plurality of oblique supports 620. The plurality of oblique supports 620 are arranged at intervals along the circumference of the support cylinder 610 on the outer periphery of the support cylinder 610. The plurality of oblique supports 620 are used to jointly support the support cylinder 610 so that the axial direction of the support cylinder 610 can be kept consistent with the Z-axis direction. Among them, each oblique support 620 can be made of angle steel. The position of the support cylinder 610 can be fixed by each oblique support 620, thereby improving the support and limiting capacity of the support assembly 600.

[0080] like Figure 1 As shown, one end of the output pipe 400 is connected to the second connecting pipe 300 through the third elbow 53, and the other end is used to output concrete downward. Among them, the third elbow 53 can be an L-shaped elbow or a V-shaped elbow, etc., which is used to change the direction of the output pipe 400. For example, the output pipe 400 can be a hard pipe arranged in the horizontal direction. The output pipe 400 is mainly used to pour concrete within a certain range. Among them, the output pipe 400 can be a carbon steel pipe. The output pipe 400 can be a straight pipe of fixed length, and its length can be set as needed. Alternatively, the output pipe 400 can also be assembled from multiple straight pipe sections.

[0081] In the present application, the output pipe 400 can make a circular motion around the Z axis. Specifically, the output pipe 400 can make a circular motion in the horizontal direction with the end connected to the third elbow 53 as the center and the length of the output pipe 400 as the radius. Thus, the concrete can be poured in a circular area through the output pipe 400, effectively increasing the pouring area of ​​the construction device.

[0082] See also Figure 1 In one embodiment, the second connecting pipe 300 includes a first tube body 310 and a second tube body 320 coaxially arranged up and down, and a rotary joint 330 connected between the first tube body 310 and the second tube body 320. The lower end of the first tube body 310 is connected to the first connecting pipe 200 through the second elbow 52, ​​the upper end of the first tube body 310 is connected to the lower end of the second tube body 320 through the rotary joint 330, and the upper end of the second tube body 320 is connected to the output pipe 400 through the third elbow 53. The rotary joint 330 can be a pipeline rotary joint, which can realize the relative rotation of the connected pipelines and achieve the purpose of conveying materials. Therefore, through the rotary joint 330, the second tube body 320 can rotate around the Z axis relative to the first tube body 310, so as to drive the output pipe 400 to make a circular motion around the Z axis.

[0083] In this embodiment, by setting the second connecting pipe 300 to a structure including a first tube body 310, a second tube body 320 and a rotating joint 330, the second tube body 320 can rotate around the Z axis under the action of the rotating joint 330, thereby driving the output pipe 400 to perform circular motion around the Z axis.

[0084] In other embodiments, the second connecting pipe 300 may be an integral hard pipe. Meanwhile, a rotary joint 330 is provided between the second connecting pipe 300 and the third elbow 53, so that the third elbow 53 and the output pipe 400 can perform a circular motion around the Z axis under the action of the rotary joint 330.

[0085] In one embodiment, the second connecting pipe 300 and the output pipe 400 are connected in a quick-release manner. That is, the second connecting pipe 300 and the third elbow 53 are connected in a quick-release manner, and the third elbow 53 and the output pipe 400 are connected in a quick-release manner. For example, the end of the second connecting pipe 300 and the end of the third elbow 53 can be fastened and fixed by a clamp. The end of the third elbow 53 and the end of the output pipe 400 can also be fastened and fixed by a clamp.

[0086] See also Figure 1 In one embodiment, the construction device further includes an output hose 500, which is connected to an end of the output pipe 400 away from the second connecting pipe 300 through a fourth elbow 54. The fourth elbow 54 may be an L-shaped elbow or a V-shaped elbow, etc., which is used for transition connection of the output hose 500 so that the output hose 500 can output concrete downward.

[0087] The output hose 500 may be a rubber hose, which may be sleeved on one end of the fourth elbow 54, and the rubber hose and the end of the fourth elbow 54 may be tied and fixed by a steel wire or a clamp.

[0088] The fourth elbow 54 is connected to the output pipe 400 in a quick-release manner. For example, the end of the output pipe 400 and the end of the fourth elbow 54 can be fastened and fixed by a clamp.

[0089] In this embodiment, the output hose 500 is provided. Since the output hose 500 is flexible, the pouring orientation can be changed arbitrarily, thereby further increasing the concrete pouring area of ​​the construction device.

[0090] See also Figure 1 and Figure 2 When the construction device of the embodiment of the present application is in use, the first end of the input pipe 100 extends out of the temporary door 20 of the storage tank 10, and is quickly connected to the discharge pipe of the concrete pump equipment through a steel clamp. The second end of the input pipe 100 extends into the storage tank 10 until it is connected to the vicinity of the tank wall on the opposite side of the temporary door 20 of the storage tank 10. The first connecting pipe 200 is connected to the second end of the input pipe 100 through the first elbow 51. The second connecting pipe 300 is connected to the first connecting pipe 200 through the second elbow 52. The output pipe 400 is connected to the second connecting pipe 300 through the third elbow 53. The output hose 500 is connected to the output pipe 400 through the fourth elbow 54.

[0091] The input pipe 100 is horizontally supported on each support bracket 700 along the X-axis direction. The second connecting pipe 300 can be arranged vertically upward along the Z-axis direction and supported and fixed by the supporting assembly 600. The first connecting pipe 200 can be horizontally connected between the input pipe 100 and the second connecting pipe 300 along the Y-axis direction.

[0092] Start the concrete pump equipment to pour concrete into the area near the tank wall opposite to the temporary door 20 in the tank through the input pipe 100, the first connecting pipe 200, the second connecting pipe 300, the output pipe 400 and the output hose 500. During the pouring construction, the concrete pouring construction sequence can be progressive from the tank wall near the side opposite to the temporary door 20 to the temporary door 20. During the pouring process, the pouring direction is controlled by adjusting the length of the input pipe 100 and rotating the output pipe 400. And the two sides of the input pipe 100 can be poured step by step alternately.

[0093] During pouring construction, in some dead corners where concrete cannot be poured in place, construction workers can use a small wheelbarrow or square shovel to transfer the concrete to the place and then level the concrete.

[0094] See also Figure 3 As shown, in one embodiment of the present invention, a large flat-bottom tank concrete leveling layer construction method (hereinafter referred to as the construction method) is also provided, which is constructed using any of the construction devices described above. The construction method includes:

[0095] S10, connecting the first end of the input pipe 100 to the concrete supply equipment, extending the second end of the input pipe 100 into the target area in the storage tank 10, so that the axis of the input pipe 100 intersects with the central axis of the storage tank 10. The target area is the inner area of ​​the tank wall opposite to the temporary door 20 of the storage tank 10.

[0096] S20, connecting the first connecting pipe 200 to the second end of the input pipe 100, connecting the second connecting pipe 300 to the end of the first connecting pipe 200 away from the input pipe 100, connecting the output pipe 400 to the end of the second connecting pipe 300 away from the first connecting pipe 200, and pouring concrete into the target area through the output pipe 400. Specifically, in S20, the quick connection between the pipelines can be achieved through the elbow.

[0097] S30, when a certain position in the target area is poured, the output pipe 400 is rotated to pour concrete to the next position in the target area. Figure 4 As shown, when pouring area A1, after the concrete is poured at the position below the current position of the output pipe 400, the output pipe 400 can be rotated clockwise or counterclockwise to pour concrete at the next position of the A1 area until the entire A1 area is poured.

[0098] S40, when the target area is poured, the length of the input pipe 100 is adjusted so that the output pipe 400 can pour concrete in the next area in the X-axis direction. Figure 4 As shown, after area A1 is poured, the length of the input pipe 100 can be adjusted so that the output pipe 400 can pour area A2; after area A2 is poured, the length of the input pipe 100 can be adjusted again so that the output pipe 400 can pour area A3.

[0099] In the process of pouring one area at a time from the target area to the temporary door 20 of the storage tank 10, the first connecting pipe 200 can be alternately arranged on both sides of the input pipe 100, and the areas on both sides of the input pipe 100 can be alternately poured through the second connecting pipe 300 and the output pipe 400.

[0100] For example, Figure 4 As shown, after pouring area A1, the first connecting pipe 200 is reconnected to the second end of the input pipe 100, so that the first connecting pipe 200 can pour area B1 through the second connecting pipe 300 and the output pipe 400. When area B1 is poured, the length of the input pipe 100 is adjusted to pour area B2. Then, the first connecting pipe 200 is reconnected to the second end of the input pipe 100, so that the first connecting pipe 200 can pour area A2 through the second connecting pipe 300 and the output pipe 400, and so on. That is, in this embodiment, the construction personnel can perform the pouring construction in the order of A1→B1→B2→A2→A3→B3, for details, please refer to Figure 4 Indicated by the dotted arrow direction.

[0101] It can be understood that in other embodiments, during the process of pouring the temporary door 20 of the storage tank 10 from the target area to the area one by one, the first connecting pipe 200 can also be kept arranged on one side of the input pipe 100, and the areas on this side are poured one by one through the second connecting pipe 300 and the output pipe 400. After the pouring of the area on this side is completed, the areas on the other side of the input pipe 100 are poured one by one. That is, if Figure 4 As shown in the example, the construction workers can perform pouring construction in the order of A1→A2→A3→B1→B2→B3.

[0102] Alternatively, in other embodiments, the construction device may be configured with two first connecting pipes 200, as well as two second connecting pipes 300, two output pipes 400 and two output hoses 500. At the same time, the second elbow 52 may be a T-shaped three-way elbow. Connect one interface of the T-shaped three-way elbow to the second end of the input pipe 100, and connect the two first connecting pipes 200 to the other two interfaces of the T-shaped three-way elbow respectively, so that the two first connecting pipes 200 can extend to the two side areas of the input pipe 100 respectively. Then, the two second connecting pipes 300, the two output pipes 400 and the two output hoses 500 are respectively connected to the two first connecting pipes 200 in sequence. Therefore, in the process of pouring one area at a time from the target area to the temporary door 20 of the storage tank 10, the construction device can pour the areas on both sides of the input pipe 100 at the same time. That is, as Figure 4 As shown in the example, the construction workers can perform pouring construction in the order of A1, B1 → A2, B2 → A3, B3.

[0103] The construction device and construction method of the embodiment of the present application have the advantages of simple construction device structure, convenient installation and disassembly, convenient construction, and effective reduction of labor intensity. During the construction process, the concrete pouring construction of most areas in the tank can be completed by adjusting the length of the input pipe and rotating the output pipe, reducing the workload of transporting concrete from the middle of the tank to the surrounding area of ​​the tank, avoiding the crushing and damage of the bottom glass bricks by small transport bucket trucks, and reducing the labor intensity of workers in the construction of the concrete leveling layer.

[0104] The construction device and construction method of the embodiment of the present application can effectively prevent the transport bucket truck from damaging the bottom foam glass brick insulation layer during the process of transporting concrete to the surrounding of the storage tank, thereby ensuring the insulation performance of the bottom insulation layer, while reducing the intensity of workers and reducing the labor cost of construction.

[0105] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.
