Water-stopping steel plate splicing joint structure and construction method thereof

The invention discloses a water-stopping steel plate splicing joint structure and a construction method thereof, and relates to the technical field of building construction. The structure and the method thereof aim to solve the problems that the welding quality and the working efficiency are low in existing water-stopping steel plate splicing joint welding construction. The structure involves at least two water-stopping steel plates which are lapped end to end in the length direction, at least two water-stopping rubber strips which are arranged at the lap joint between two adjacent water-stopping steel plates, and blocking strips which are located on the two sides of the lap joint between two adjacent water-stopping steel plates, wherein the blocking strips cover the gap between two adjacent water-stopping steel plates and the end parts of the water-stopping rubber strips, and the water-stopping rubber strips and the blocking strips are used for transversely and longitudinally sealingthe lap joint between two
