Quality check of the hydraulic structures

1. Quality Control In Minor Irrigation

2. OBJECTIVES: Assisting construction staff to verify and adhere to use appropriate quality materials as prescribed in tender specifications. Advice on routine basis to ensure workmanship, work process and finishing meets required standard as per tender specification. Inspect works randomly during construction activities and prevent any issues in quality adherence. Carry out necessary tests on construction materials before commencement of the work as requested by the concerned construction staff. Ensure quality of finished products after completion of work and also direct the construction staff in case of flaws in Quality.

3. Tests in Quality Control Organisation 1.Minor Irrigation Tanks: Visual soil classification. Water content determination by oven drying method and infrared moisture method. Specific gravity test(Pycnometer and density bottle method) Grain size analysis Sieve analysis Hydrometer analysis Consistency limits Liquid limit test(by Casagrande’s and cone penetration method) Plastic limit test Shrinkage limit test In-situ density tests Core-cutter methods Sand replacement method

4. Shear strength tests Unconfined compression test Direct shear test Triaxial test (Undrained Unconsolidated) Co-efficient of Permeability test Constant head test Variable head test 2.Checkdams/BCB/Pickups etc and Other Concrete Works: Tests on Cement Tests on Aggregates Tests on Concrete Tests on Steel Reinforcement Tests on Hardened Properties of Concrete Non-destructive Testing
