The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0026] The embodiments of the present application will be described below according to the overall structure of the present application.

[0027] Embodiment one

As can be seen above, the side plate module 3 is easy to assemble, and the welding process is simplified, which greatly avoids the disadvantages of water tank leakage caused by welding errors;

[0030] The first bottom side pressure self-balancing truss combined component 8 is formed by combination welding of the first upper inclined slotted hollow square steel pipe 801, the first lower inclined slotted hollow square steel pipe 802, the first unslotted hollow square steel pipe 803, the first U-shaped pull rod 804, the first upper top plate gasket 805 and the first side plate gasket 806;

[0031] Specifically, the upper surface of the first lower inclined slotted square steel pipe 802 is connected to the lower surface of the first unslotted hollow square steel pipe 803 by welding, and the upper surface of the first unslotted hollow square steel pipe 803 is connected to the lower surface of the first upper inclined slotted hollow square steel pipe 801 by welding.

[0032] Two first U-shaped pull rods 804 are welded and fixed inside the first unslotted hollow square steel pipe 803, and the first U-shaped pull rod 804 is welded to the surface of the first unslotted hollow square steel pipe 803, wherein the U-shaped hole is flush with the edge of the first unslotted hollow square steel pipe 803;

[0033] The first lower inclined unslotted hollow square steel pipe 807 is fixed outside the first lower inclined slotted hollow square steel pipe 802, and the bottom of the first lower inclined unslotted hollow square steel pipe 807 is fixedly connected to the first bottom plate gasket 808 which is fixedly connected to the bottom plate 1, wherein the first lower inclined unslotted hollow square steel pipe 807 is combination welded to the first lower inclined slotted square steel pipe 802 and the first bottom plate gasket 808;

[0049] Further, the abdominal pull rod 907 is placed between the two second U-shaped pull rods 904 in a crossed manner and is connected in a welded manner, and the deformation degree of the second U-shaped pull rod 904 is greatly constrained through the welding of the abdominal pull rod 907, so that the structure is further strengthened, and finally the second bottom-side pressure self-balancing truss combined component 9 with a built-in length of four meters is combined and welded;

[0050] The second bottom side pressure self-balancing truss combined component 9 with four meters built-in is formed by assembling and welding, and a standard and unified welding assembly module can be formed by pre-factory assembly and welding. The combined welding component greatly reduces the influence of external factors and welding operation, increases the stress contact area, balances the system stress, reduces the tearing of the side plate module 3 and the overall collapse caused by stress concentration of the pull bar, has a large internal activity space, and greatly facilitates subsequent water tank welding, artificial cleaning and construction and maintenance.
