1. Make every effort 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 not less than 20mm.

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

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

5. When the water-stop steel plate passes through the column hoop reinforcement, the hoop reinforcement can be cut to form an open hoop, which is then welded onto the steel plate.

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