1. Strive to ensure the waterstop steel plate is aligned with the centerline of the wall.

2. The welding between the two steel plates must be full and double-sided, with the overlap of the steel plates not less than 20mm.

3. Corner treatment for walls: 1. Whole sheet steel bending; 2. T-shaped welding; 3. 7-shaped welding.

4. Support welding for waterstop steel plates can be done by spot welding small reinforcing bars onto the main bars.

5. When the waterstop steel plate passes through the column stirrups, the穿过过的stirrups can be severed to form an open stirrup, which is then welded to the steel plate.

6. The "opening" of the waterstop steel plate faces the upstream side.
