1. Strive to ensure the waterstop steel plate is centered in the wall line.

2. The weld between the two steel plates should be full and double-sided, with a lap of at least 20mm.

3. Wall corner treatment: 1. Full steel plate bending; 2. T-shaped welding; 3. 7-shaped welding.

4. The support welding for the waterstop steel plate can be spot-welded with small rebars onto the main reinforcement.

5. When the waterstop steel plate passes through the column hoop reinforcement, the hoop reinforcement can be severed to create an open hoop, which is then welded onto the steel plate.

6. The "opening" of the water-stop steel plate faces the upstream side.
