1. Strive to ensure the waterstop steel plate is in 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 of walls: 1. Whole sheet metal bending; 2. T-shaped welding; 3. 7-shaped welding.

4. Support welding for waterstop steel plate can be done using small steel bars spot-welded onto the main reinforcing bars.

5. When the waterstop 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.
