Problems

  • Excessive retrogression (4-7 ft at high-low discharge respectively);
  • Un-dissipated energy causing damages to friction blocks, inverted filter blocks and stone apron;
  • River approaches right half of barrage and causes parallel flow close to the structure;
  • 236 pressure pipes are working out of 327 installed; and
  • Operational problems of gates and hoists:
    • Bottom portion of skin plates and trusses of gates damaged- reduction in cross section;
    • Erosion and corrosion of roller tracks;
    • Abrasion of roller trains and rocking system;
    • Breaking of roller guards and
    • Cumbersome manual mechanism.
The Project
  • Construction of a Subsidiary weir 800 ft downstream of the existing barrage;
  • Extension of downstream guide banks;
  • Construction of spur along right bank upstream of the barrage to improve river approach;
  • Strengthening and raising of guide banks and marginal bunds;
  • Rehabilitation of abandoned Kalabagh railway bridge;
  • Replacement of gates and hoisting system and its automation;
  • Installation of vibrating wire piezometers; and
  • Rehabilitation and up-gradation of building and infrastructure at the barrage and in Canal Colony.
