Splice plate with high structural strength and high-strength water tank thereof

The utility model discloses a splice plate with high structural strength and a high-strength water tank thereof. The splice plate comprises an upper arc-shaped plate, a middle linear plate and a lower arc-shaped plate; the water tank is formed by assembling and splicing a plurality of splicing plates; according to the splicing plate, the upper arc-shaped plate, the middle linear plate and the lower arc-shaped plate are sequentially connected from top to bottom in an end-to-end mode, the outer side face of the whole splicing plate is of an arc-shaped face structure formed by convex and linear staggered distribution, the stress area is greatly increased, the stress strength is improved, and the service life of the splicing plate is prolonged. The embedded grooves are formed in the middles of the outer side faces of the upper arc-shaped plate, the middle linear plate and the lower arc-shaped plate respectively, the outwards-protruding reinforcing protrusions are arranged in the middles of the embedded grooves, a
