Notes on installation and precautions: 1. The concrete boundary * * * for fixing the waterstop shall be kept flat and dry. Before installation, * * * boundary * * * * scum dust and sundries, * * * steel nail or adhesive shall be used to fix the waterstop at the determined installation position. But * * * with grouting pipe must be placed on the original concrete boundary * * *. 2. When the grouting pipe type is connected with the water swelling waterstop, * * * parallel lapping method shall be adopted, and no breakpoint shall be left between them. The waterstop * * * steel nail at the connection shall be strengthened and fixed, and the reserved grouting connection pipe on the waterstop shall be sleeved onto the connecting two-way joint on another equal waterstop. 3. According to the length of the installed waterstop, a three-way joint shall be installed at about 30 meters. The straight ends of the three-way joint are about one end inserted into the waterstop, one end into the grouting connection pipe, and the other T-shaped end shall be inserted into the standby * * * grouting, so as to inject * * * slurry to stop water when the gap leaks. 4. The grouting connecting pipe in the connected waterstop must be firmly bonded with the tee connector, and the grouting pipe of the installed waterstop must be ensured to be smooth. The standby * * * grouting pipe installed on the tee shall be placed in the direction of the inner wall. 5. There is a bottle of grouting pipe adhesive in each box (used as a * * * when connecting the grouting pipe with the two-way and three-way pipes on the waterstop), and a standby * * * grouting pipe connected with the three-way pipe and put into the inner wall. |
