Urea Silo Hanger
Urea Silo Hanger
Problem:
- Additional production line increased the load of urea on conveyer, need to increase the load bearing capacity of RCC hanger structure
Solution:
- Hanger verticals strengthened with carbon fiber laminates and wraps.
- Hanger beams jacketed with RCC, using stay-in FRP formwork.
- Design build solution by Sanrachana. Job completed with minimal shutdown
RETROFITTING A PRILLING TOWER
Problem:
- Lift shaft wall showed cracks. Deflection was observed. Honey combing was noted. Staircase columns showed local buckling and sagging of beams.
Solution:
- Single layer 600GSM CFRP was applied inside and outside lift shaft wall and on beam column junctions
- Treaded rods were drilled through walls with additional reinforcement and conventional jacketing was performed with micro-concrete to strengthen weak bottom portion.
- Carbon fiber applied in beam column junctions was coated with UV resistant PU coat.
- On exposed side of lift shaft wall, CFRP surface was roughened by sand pasting, followed by plastering and painting.
