Spillway Steel Plate Lining – Kaligandaki-A Hydropower Station

Spillway Steel Plate Lining – Kaligandaki-A Hydropower Station

This project involved the precision installation of steel plate lining on the spillway chute of the Kaligandaki-A Hydropower Station, a 144 MW facility located in Syangja District. The work aimed to enhance the spillway’s durability, hydraulic performance, and resistance to abrasion caused by high-velocity water flow and sediment load.

Through the use of high-grade structural steel plates, advanced anchoring systems, and precision alignment techniques, the project successfully strengthened the spillway surface and improved its long-term operational reliability under demanding flow conditions.

Scope of Work

Steel Plate Installation:

  • Precision-fabricated high-grade steel plates were anchored to the spillway surface using advanced fixing and alignment techniques.

Structural Reinforcement:

  • Existing concrete substrate was inspected and reinforced to ensure optimal bonding and long-term stability of the lining.

Surface Protection:

  • Targeted zones received additional corrosion-resistant coating to improve wear and chemical resistance.

Why It Matters

This project demonstrated our capability to execute precision-grade structural works in complex hydropower environments. The steel lining not only met technical requirements but also enhanced the long-term resilience and operational safety of the spillway under high-velocity flow conditions.
