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

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

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

4. The support welding of waterstop steel plates can be spot-welded with small rebars onto the main rebars.

5. When the waterstop steel plate passes through the column hoop reinforcement, the hoop reinforcement can be cut and made into an open hoop, then welded onto the steel plate.

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