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 not less than 20mm.

3. Wall corner treatment: 1. Sheet metal bending; 2. T-joint welding; 3. 7-joint welding.

4. The support welding of the waterstop steel plate can be spot-welded with small reinforcing bars onto the main steel 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.
