Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fluid storage tank having a bend panel repeatedly bent and a concrete wall,

The present invention relates to a fluid storage tank, and more particularly, to a fluid storage tank, which is capable of effectively supporting a load by integrally forming a panel and a concrete wall integrally formed by repeatedly bending the side wall, The present invention relates to a fluid storage tank capable of effectively reducing the manufacturing cost and reducing the manufacturing cost and the construction time by changing the structure of the side wall portion to be operated.

The present invention also relates to a method of constructing such a fluid storage tank.

Generally, a concrete water tank is used as a large reservoir for storing and supplying water in water supply and various water storage facilities.

Concrete water tanks are advantageous in that they have high load bearing capacity and excellent durability. However, there is a concern that water is contaminated due to components eluted from concrete and the storage water environment is drastically deteriorated during long-term use.

In order to solve such a problem, a water tank having a panel 10 attached to the inner surface of the concrete wall 12 as shown in Fig. 1 has been proposed. Since the panel 10 is made of a composite panel coated with metal, synthetic resin, or the like, it is possible to prevent the contaminants from being eluted even when used for a long period of time. Such a concrete water tank is disclosed in Korean Patent Registration No. 1164215 and the like.

However, since the panel 10 has a substantially flat planar structure, the panel 10 itself has a problem that the load-bearing capacity is very small. Also, since the panel 10 has a substantially flat planar structure, there is a problem that the coupling strength with the concrete wall is weak.

In addition, the concrete water tank has the entire side wall and the roof as a whole composed of the concrete wall 12 and the panel 10, and this configuration is effective not only in the portion where the load acts largely (for example, Since the concrete wall 12 is also applied to a small portion (for example, the upper part of the side wall), the construction cost and the construction period are increased.

Further, when the concrete is laid to form the concrete wall, the panel 10 serves as a formwork, but the load bearing capacity of the panel 10 is weak, so that a bucket (not shown) supporting the panel in the water tank need. As a result, the construction of the water tank is complicated and the construction time is long.

SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above problems, and it is an object of the present invention to provide a fluid storage tank in which a panel installed on the inner surface of a concrete wall has a large load bearing capacity.

Another object of the present invention is to provide a fluid storage tank in which the panel is integrated with a concrete wall.

It is still another object of the present invention to provide a fluid storage tank capable of reducing the manufacturing cost and the construction time of a water tank by making the structure of a portion where a load largely acts and the structure of a small portion different from each other.

It is another object of the present invention to provide a fluid storage tank in which a panel serves as a mold when concrete is poured to form a concrete wall, and a tile for supporting the panel is not required.

It is still another object of the present invention to provide a method of constructing such a fluid storage tank.

In order to solve the above problems, a fluid storage tank according to the present invention includes: panels 120, 120a, 320, and 420 installed to be in contact with a fluid stored in an internal space; And a concrete wall 110 formed on the rear of the panels 120, 120a, 320 and 420 and having concrete poured into the panels 120, 120a, 320 and 420, .

The panels 120, 120a, 320, and 420 include a main body 121, 321, and 421; Protrusions formed to protrude the main bodies 121, 321, and 421 to increase the section modulus of the panel; 322 and 422 for coupling with the neighboring panels 120, 120a, 320 and 420 are formed by bending both ends of the main body 121, 321 and 421, Connection portions 127, 327, and 427 formed therein; And engaging portions 128 and 328 provided at upper and lower ends of the main body 121 (321 and 421) and having fastening holes 129, 329 and 429 for engaging with neighboring panels 428).

The end portion of the connection portion 127 is bent perpendicularly to be parallel to the main body 121 to form the bent portions 126a and 126c. The bent portions 126a and 126c serve to increase the strength of the panel. The bent portion 126a has a wide feature and the bent portion 126c has a somewhat narrow width. This facilitates workability such as installation of a tie and a connecting member. A through hole 126b through which the connection tie 137 passes is formed in the bent portion 126a.

The protrusions are continuously formed and repeatedly formed along the longitudinal direction of the main body 121 (321) and (421).

Another fluid storage tank according to the present invention differs in the structure of the sidewall portion P1 in which the load is relatively small and the sidewall portion P2 in which the load is relatively large.

Specifically, the portion P2 is formed of the panels 120, 120a, 320 and 420 and the concrete wall 110. The portion P1 is composed of the panels 10 and 20, and the panels 10 and 20 have a generally flat planar structure.

The protrusions include first protrusions 123, 323, and 423 protruding toward the inner space; And second protrusions 125, 325, and 425 formed to protrude outward. The first protrusions 123, 323, and 423 and the second protrusions 125, 325, and 425 are formed alternately.

The first projections 123, 323 and 423 coincide with the inner space side surface 128a of the engaging portions 128, 328 and 428, and the second projections 125, 325 and 425 coincide with each other. Is preferably coupled to a widthwise center of the engaging portions 128 and 328 such that the engaging portions 128 and 328 are spaced apart from the outer side surface 128b of the water tank.

In addition, according to the present invention, the width w1 (w2) and the bending depth (d1) of the first and second protrusions can be differently formed according to the load,

The connecting portion 328 of the panel 320 has an arc shape conforming to the curvature of the side wall of the water tank and the bending angle u of the connecting portion 327 is larger than 90 ° and smaller than 120 °.

The fastening holes 129, 329 and 429 may be formed on the front side (inside the water tank) and the back side (outside the water tank) of the main body, ) 329 and 429 are connected to the adjacent panel and an internal stiffener 30 for supporting the water pressure at the time of installation. Bolts 129, 329, and 429 formed on the outside of the water tank may be provided with bolts for coupling neighboring panels. A method of dewatering water in a water tank to offset the pressure acting on concrete when concrete is poured to form the concrete wall body 110 is disclosed in the patent registration No. 1090310 of the present applicant.

The panels 120, 120a, 320 and 420 may have buried bars 151, 152 and 153 installed to be coupled with the main body and embedded in the concrete of the concrete wall body 110. The embedding bars 151, 152 and 153 prevent the panel from being detached from the concrete wall 110.

As an alternative to the buried bars 151, 152 and 153, or wedge structures may be used with the buried bars 151, 152 and 153.

The wedge structure may be formed by bending the side surfaces of the first and second protrusions 123 and 125. Specifically, the wedge structure is formed by bending the side surfaces of the first and second protrusions 123 and 125 so that the width L2 of the inner side 124b is wider than the width L1 of the inlet side 124a . The concrete on the inner side 124b acts as a wedge to prevent the panel from being separated from the concrete wall 110 when the concrete is laid.

Another aspect of the present invention is to provide a method of constructing a fluid storage tank comprising the steps of: (a) providing panels 120, 120a, 320 and 420, wherein neighboring panels 120, 120a, 320, To couple; (b) installing a flow path foam 140 so as to be spaced apart from the panels 120, 120a, 320, and 420 by a predetermined distance; (c) connecting the panel 120, 120a, 320, and 420 to the flow foams 140 using the connection ties 137; And (d) forming a concrete wall 110 by placing concrete between the panel 120, 120a, 320 and 420 and the flow path foam 140 after the step (c) .

120, 120, 320, and 420 when the concrete is poured. Specifically, in the present invention, when the water tank is constructed, the internal stiffener 30 is installed so as to connect the opposed panels 120. The internal stiffener 30 is made of a water- It serves to support hydraulic pressure and concrete load and is removed after completion of concrete curing. On the other hand, the internal stiffener 30 is installed before the step (d). A method for dewatering water in a water tank to cancel the pressure acting on the concrete is disclosed in the patent registration No. 1090310 of the present applicant.

Conventionally, in order to support a concrete load, the trams are installed at extremely narrow intervals (for example, 50 cm to 60 cm intervals). However, in the present invention, the inner reinforcement 30 and the water tank It is possible to omit complicated steps.

The fluid storage tank according to the present invention has the following effects.

First, the panels 120, 120a, 320, and 420 installed on the inner surface of the concrete wall body 110 have a large load bearing capacity. Accordingly, the thickness and the like of the concrete wall body 110 can be reduced and the reinforcing bars and the like used for the concrete wall body 110 can be reduced.

Second, the panels 120, 120a, 320 and 420 can be integrated with the concrete wall 110.

Thirdly, the portion (P2, for example, the lower portion or the underground portion of the side wall) where the load is largely applied is constructed by the bending panels 120, 120a, 320 and 420 and the concrete wall body 110, (P1, for example, an upper portion or a ground portion of the side wall) can reduce the water tank production cost and the construction time by using the general flat panel 10 (20).

Fourth, the panels 120, 120a, 320 and 420 serve as dies for concrete to form the side wall concrete wall 110 and support the panels 120, 120a, 320 and 420 There is no need for a hike.

Fifth, a separate lining process is reduced and a method of constructing a sanitary fluid storage tank is provided.

Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely examples of the present invention and are not intended to represent all of the technical ideas of the present invention, so that various equivalents And variations are possible.

Hereinafter, a case where water is stored in a fluid storage tank to explain a fluid storage tank according to the present invention will be described as an example. However, the scope of right of the present invention should not be construed as being limited to a water tank.

In addition, the x, y, and z axes shown in the drawings of the present specification mean axes perpendicular to each other, which are axes of the cartesian Cartesian coordinate system, to facilitate understanding of the drawings.

Example 1 (rectangular parallelepiped type water tank)

FIG. 2 is a perspective view showing a water tank according to a first embodiment of the present invention, and FIG. 3 is a sectional view taken on line A-A 'of FIG.

Referring to the drawings, a water tank 100 includes a bottom concrete 101, four side walls vertically installed on the bottom concrete 101, and a roof installed at the top of the side wall.

A metal plate 102 is installed on the bottom concrete 101. The bottom concrete 101 serves to support side walls, roofs, and the like.

The side walls include a concrete wall 110 and a panel 120 integrated with the concrete wall 110.

4, the panel 120 includes a main body 121, first and second protrusions 123 and 125 formed to protrude from the main body 121, and both ends in the width direction of the main body 121, (Not shown). The panel 120 used in the present invention may be made of a metal such as stainless steel, but may also be made of a composite panel coated with a resin or the like.

The first protrusion 123 is formed by bending the main body 121 so as to protrude in one direction. The first protrusion 123 is formed so as to be continuous along the longitudinal direction of the main body 121 (z direction in FIG. 4).

The second protrusion 125 is formed by bending the body 121 so as to protrude in a direction opposite to the one direction. Therefore, when the first protrusion 123 protrudes toward the inner space of the water tank, the second protrusion 125 faces the outside of the water tank. The second protrusions 125 are formed to be continuous long along the longitudinal direction.

The first protrusion 123 and the second protrusion 125 are alternately and repeatedly formed.

As described above, since the first protrusion 123 and the second protrusion 125 are alternately formed, the panel 120 has a larger section modulus than the flat panel of the same thickness, and thus has greater resistance to water pressure (load). For example, when the thickness of the main body 121 is 1.5t and the bending angle (S in FIG. 5) is approximately 135 degrees, the bending causes the material to increase by about 25% compared with a flat panel covering the same area But has a load bearing capacity (resistance against water pressure) of about 6 times as compared with the case where there is no bending. Here, the load supporting force (resistance against water pressure) refers to the resistance against bending or buckling when water pressure or earth pressure acts.

Since the load bearing capacity of the panel 120 is large, it is possible to reduce the thickness of the concrete wall 110 or reduce the amount of the reinforcing bars used for the concrete wall 110. [

In addition, since the load bearing capacity of the panel 120 is large, the thickness of the panel can be greatly reduced. (Not shown) for supporting the panel 120 when the sidewall concrete is poured is not required. Accordingly, the water tank construction can be simplified, the construction cost can be reduced, and the construction period can be shortened.

The first projecting portion 123 coincides with the water tank inner side surface 128a of the engaging portion 128 and the second projecting portion 125 is spaced apart from the outer side surface 128b of the engaging portion 128 G " in the widthwise direction of the coupling portion 128). This configuration helps to integrate the panel 120 and the concrete wall 110 by enlarging the portion embedded in the concrete.

The width w1 of the first protrusion 123 and the width w2 of the second protrusion 125 and the bending depth d1 can be adjusted according to the magnitude of the load. For example, if the load is large, the bending depth d1 can be increased to cope with this. With this configuration, even if the magnitude of the load is changed, the panel can be manufactured using a material (stainless steel panel) having the same thickness.

In addition, since the first and second protrusions 123 and 125 are formed on the panel 120, the coupling area with the concrete wall 110 is large and thus the coupling force is large. Accordingly, the panel 120 and the concrete wall 110 Can be integrated. Further, when the bending angle is 90 degrees or less, the problem of separating the panel from the concrete wall can be solved.

The connecting portion 127 is a portion bended such that both end portions in the width direction of the main body 121 are perpendicular to the y-axis (Fig. 4). The connection portion 127 is used for coupling with the neighboring panel 120, and a plurality of coupling holes 122 are formed in the connection portion 127 for this purpose. That is, as shown in FIG. 6, the panels 120 are arranged so that the connecting portions 127 of the neighboring panels 120 are in contact with each other, and are then fastened to each other by using the connecting member 130.

The end of the connection part 126 is bent in parallel with the main body 121 to form the bent parts 126a and 126c. The bent portions 126a and 126c increase the strength of the panel.

One of the bent portions 126a of the bent portions 126a and 126c is formed wider than the other bent portion 126c and the through hole 126b is formed in the bent portion 126a. The through-hole 126b is provided with a connection tie 137 penetrating therethrough.

A plurality of panels 120 may be coupled to each other in the lateral direction as well as a plurality of vertically coupled panels 120. For this purpose, 128).

The engaging portion 128 is formed of a flat iron coupled to the upper and lower ends of the main body 121. The flat iron is coupled to the main body 121 so as to be perpendicular to the z axis and has a rectangular or arcuate shape depending on the shape of the tank .

A plurality of coupling holes 129 are formed in the coupling portion 128. As shown in Fig. 5, the fastening holes 129 are formed on the front side (inside the water tank) of the main body 121 and the back side (outside the water tank) of the main body 121, respectively.

A fastening hole 129 formed on the front side of the main body (on the inner side of the water tank) is used to connect the internal stiffener 30 (which may be embodied as a round bar, an angle, or the like) as shown in Fig. When constructing the water tank, the internal stiffener 30 is installed to connect the panels 120 facing each other, and serves to support the water pressure dewatered in the concrete until the concrete pouring and curing are completed. The internal stiffener 30 is removed after completion of concrete curing. A method for dewatering water in a water tank to cancel the pressure acting on the concrete is disclosed in the patent registration No. 1090310 of the present applicant. However, in the present invention, it is sufficient that the internal reinforcement 30 and the water in the water tank are dewatered, so that the complicated dams Can be omitted.

A fastening hole 129 formed on the rear side (outside the water tank) of the main body 121 is used to engage the engaging portions 28 of the upper and lower panels 120 with each other. Specifically, when the two panels 120 are vertically coupled to each other, the coupling portions 128 of the upper and lower panels 120 are disposed to be in contact with each other, and then the bolts are fastened to the coupling holes 129 . This configuration is also shown in Fig.

FIGS. 6 and 7 show that the panel 120 and the euro foam 140 are combined to form a concrete wall.

As shown in the figure, a plurality of panels 120 are installed to be connected to each other in the lateral direction, and the flow path foam 140 is disposed to be spaced apart from the panel 120 by a predetermined distance. Concrete is placed in the space between the Euro foam 140 and the panel 120 to form the concrete wall body 110. A reinforcing bar (not shown) for reinforcing the concrete wall 110 may be disposed in the space.

According to the present invention, a coupling member 130 is used to connect the panels laterally to each other, connect the panel 120 and the flow foams 140 to each other, and connect the flow foams 140 laterally to each other.

The engaging member 130 includes a first engaging member 131, a second engaging member 135, and a connecting tie 137. A configuration for connecting the panels 120 in a lateral direction by using the coupling member 130 and a configuration for connecting the panel 120 and the foam foam 140 to each other and a configuration for connecting the foam foams 140 in the lateral direction And the like are well known in the art and will not be described here.

When the installation of the panel 120 and the foam foam 140 is completed, concrete is poured between the panel 120 and the foam foam 140. When the concrete is cured, the foam foam 140 is removed.

The panel 120 is superior in strength to a concrete wall in comparison with a conventional panel, but may include a structure for further increasing a coupling force. Specifically, as shown in FIG. 9A, the panel 120 includes a buried bar 151 welded to the second projecting portion 125 (the portion protruding outward from the water tank) installed to connect the connecting portions 127 to each other . The embedding bar 151 is buried in the concrete wall 110 to further increase the coupling force between the panel 120 and the concrete wall 110 and prevent the panel 120 from being separated from the concrete wall 110 .

In FIG. 9A, an angle "a" is used as the embedding bar 151, but a round bar (152 in FIG. 9B) or a flat iron (153 in FIG. 9B) can be used for embedding.

9A to 9C, the embedding bars 151, 152 and 153 are provided to connect the connecting portions 127, but the embedding bar may be provided to connect the connecting portions 128 to each other. Then, the burring bars 152 and 153 can be welded to the second projection 125 (the portion protruding outwardly of the water tank).

On the other hand, Fig. 10 shows another example of the panel. 10, the same reference numerals as those in Figs. 1 to 9 denote the same elements.

The panel 120 includes a main body 121, first and second protrusions 123 and 125 formed to protrude from the main body 121, and a connecting portion 127 having both ends in the width direction at right angles, Respectively. Compared with the above-described panels, the panel 120 has a wedge structure formed on the side surfaces of the first and second protrusions 123 and 125 and a difference between the first protrusion 123 and the inside There is a difference in that the second projections 125 coincide with the outer side surfaces of the engaging portions 128. In this case,

11, the wedge structure is formed such that the side of the first and second protrusions 123 and 125 is bent so that the width L2 of the inner side 124b is smaller than the width L1 of the inlet side 124a And can be made wide. The concrete on the inner side 124b acts as a wedge to prevent the panel from being separated from the concrete wall 110 when the concrete is laid.

Fig. 12 shows another example of the panel. The panel 120a includes a main body 121, a first protrusion 123a formed to be long in the z direction, a coupling portion 128 formed at the upper and lower ends of the main body 121 and a coupling portion 127 formed at both sides of the main body 121 ). The coupling portion 128 and the coupling portion 127 of the components are the same as the coupling portion 128 and the coupling portion 127 of the panel 120, respectively.

The panel 120a is the same as the panel 120 except that the second protrusion 125 is not provided and the shape of the first protrusion 123a is different from the first protrusion 123. [ Accordingly, the panel 120a, like the panel 120, has a large load bearing capacity and can be integrated with the concrete wall 110 behind the panel 120a.

The first projecting portion 123a is formed as a protrusion formed continuously from a portion close to the upper end of the main body 121 to a portion close to the lower end, and is formed to protrude toward the space inside the water tank. The first projections 123a are repeatedly formed at predetermined intervals along the width direction (y direction).

Example 2 (rectangular parallelepiped type water tank)

FIG. 13 is a perspective view showing a water tank according to a second embodiment of the present invention, and FIG. 14 is a sectional view taken along line C-C 'of FIG. 13 and 14, the same reference numerals as those in Figs. 1 to 12 denote the same elements.

Since the water tank 200 has a small load acting on the panel 10 and the load acts largely on the panel 120 and the concrete wall 110, Differentiated.

In the present specification, the portion P2 in which the load acts largely includes a portion buried in the underground among the side walls, and the portion P1 having a small load acts only on the side wall, (E. G., The upper portion of the sidewalls).

The portion (P2) where the load of the side wall greatly acts includes a panel 120 and a concrete wall 110 formed behind the panel 120. The panel 120 is the same as the panel 120 described above and the concrete wall 110 is the same as the concrete wall 110 described above and the construction method of the panel 120 and the concrete wall 110 is the same as the above Do. In addition, the panel 120a may be used in place of the panel 120. [

The panel 10 is installed in a portion P1 having a small load, and a typical panel, for example, a synthetic resin panel or a stainless steel panel disclosed in Korean Patent Registration No. 1164215 can be used. The joining of the panel 10 and the panel 120 and the joining of the panels 10 may be performed by a conventional bolt, welding, or the like.

Thus, the water tank 200 is advantageous in that the water tank manufacturing cost and the construction time can be reduced by making the structure of the portion P2 in which the load greatly acts and the portion P1 in which the load acts small.

Third Embodiment (Cylindrical Water Tank)

FIG. 15 is a front view showing a water tank according to a third embodiment of the present invention, and FIG. 16 is a longitudinal sectional view of the water tank. 15 and 16, the same reference numerals as those in Figs. 1 to 14 denote the same elements.

The water tank 300 has the panel P2 and the concrete wall 110 and the portion P1 where the load acts largely is formed of the normal panel 20.

The water tank 300 is different from the water tank 200 in that the side wall has a cylindrical shape as a whole. Accordingly, the panel 320 used for the side wall of the water tank 300, the concrete wall 110, and the foam 140 for forming the concrete wall 110 are formed to have a predetermined curvature.

17 and 18, the panel 320 includes a main body 321, first and second protrusions 323 and 325 formed to protrude from the main body 321, And a coupling part 328 formed at the upper and lower ends of the main body 321. [

The main body 321 is formed to have a predetermined curvature in the width direction because the side wall formed by connecting the panels 320 to each other is circular.

The first and second protrusions 323 and 325 have the same structure as the first and second protrusions 123 and 125 of the panel 120 described above.

The connection portion 327 has the same structure as the connection portion 127 of the panel 120 described above. However, the bending angle u of the connecting portion 327 is greater than 90 degrees and less than 120 degrees.

The engaging portion 328 is coupled to the upper and lower ends of the main body 321 by flat iron. Since the side wall of the water tank is circular, the flat steel is formed to have a predetermined curvature. The engaging portion 328 is a portion for connecting the lower panel 320 to each other when two or more panels 320 are installed vertically and continuously. As shown in FIG. 19, the lower panel 320 can be coupled by bolts 326 passing through the fastening holes 329.

The fastening holes 329 are formed on the front side and the rear side of the main body 321, respectively. The role of the fastening hole 329 formed in the front side of the main body 321 and the function of the fastening hole 329 formed in the rear side of the main body 321 are the same as those of the fastening hole 129 described above.

As with the panels 120 and 120a described above, since the panel 320 is superior in load bearing capacity to the conventional panel, the panel 320 can be used in a portion buried in the underground or in a portion where a load acts largely among the side walls of the water tank.

On the other hand, the panel 20 is installed on the portion P1 where the load acts small, for example, on the concrete wall body 110. As the panel 20, a conventional panel, for example, a panel having a substantially flat surface without protrusions may be used.

The joining of the panel 20 and the panel 320 and the joining of the panels 20 may be performed by a conventional welding, bolt or the like.

In the above description, the lower part of the side wall of the cylindrical water tank 300 is made up of the panel 320 and the concrete wall 110, and the upper part of the side wall is made up of the panel 20 (that is, The entirety of the water tank may be composed of the panel 320 and the concrete wall body 110 (i.e., irrespective of the magnitude of the load), as in the case of the rectangular parallelepiped water tank 100 Wall and roof have the same structure), which will be apparent to those skilled in the art having referred to this disclosure.

Fourth Embodiment (Cylindrical Water Tank)

21 is an exploded perspective view showing a water tank according to a fourth embodiment of the present invention and a panel used in a water tank.

The water tank 400 includes a panel P2 and a concrete wall (not shown in Fig. 21) embedded in the basement wall of the side wall and a portion P1 exposed to the ground in the side wall of the water tank 400, Flat panels without first and second projections). That is, a panel 420 having a high load-bearing capacity and a flat panel having a relatively small load are installed in a portion P2 having a high load. This configuration has the advantage that it can effectively cope with the earth pressure or the water pressure while lowering the price of the water tank.

The panel 420 has the same curvature as the side wall of the water tank, and has a structure in which the panel 120 is laid down sideways. Accordingly, in the panel 420, the first and second protrusions 423 and 425 are formed in the transverse direction.

The panel 420 includes a main body 421, first and second projections 423 and 425, a connection portion 427, and a connection portion 428. The coupling portion 427 is formed with a coupling hole 422 for coupling with the upper and lower panels and the coupling portion 428 is formed with a coupling hole 429 for coupling with the lateral panel.

The main body 421 is formed to have a predetermined curvature in the longitudinal direction (horizontal direction) because the side wall formed by connecting the panels 420 to each other is circular.

The first protrusion 423 is formed by bending the main body 421 so as to protrude into the inner space of the water tank 400 and is continuously formed in the longitudinal direction (horizontal direction). The second protrusion 425 is formed by bending the main body 421 so as to protrude outward, and is continuously formed in the longitudinal direction (horizontal direction). The first and second protrusions 423 and 425 are alternately and repeatedly formed.

As described above, since the metal panel 420 is superior in load-bearing capacity to the conventional metal panel, it can be used for constructing the sidewall of a part buried in the underground among the side walls of the water tank.
