SOJ Pile repair
2
\\"Execution of Repair job of piles as the methodology mentioned as below. Step 1: Fix the Surface applied SRM TM Seamless Annular Shell Form (which is a high-performance Glass Fiber Reinforced Polymer (GFRP) annular forming laminate designed for creating a continuous, staying place, seamless external jacket around existing piles, columns, and similar vertical structural elements to be repaired or strengthened using suitable underwater epoxy adhesive and spacers as per site requirement. )over the prepared area of concrete section to be jacketed and cast it with Micro-concrete underwater to form a base collar ring along the periphery. Step 2: FIX SRM AF SPACERS at required Spacing in both directions and in plumb on the face of pier (also provide shear key and distribution steel bars wherever required in both directions. Step 3: Lower and fix the slide in high strength noncorrosive sacrificial SRM Annular Form Sheets in the spacers and fix it; after complete installation tie all of them together with annular tie bands for enhanced rigidity during casting. Step 4: Mixing the underwater Micro concrete and fill the same using the inlet point provided in SRM patch Form frame or pouring it in SRM Seamless Annular Shell with micro tremie pipes for better reach (for larger depths SRM Annular Form to be provided with Inlet ports for pouring Micro concrete). Use material with suitable consistency for underwater works. observe the fill through transparent window provided in form. Step 5: Allow to cure and carryout an underwater (after repair and retrofit works) inspection with photography and videography of repair , all complete as per direction of Engineer-In-charge The rate is inclusive of all consumables, materials , labours , Tool tackles, Transportation , Lodging etc. involved. The unit of measurement is in Sqm ( The Repaired area will be considered for measurement)\\"

Use material with suitable consistency for underwater works. observe the fill through transparent window provided in form. Step 6: Over water level or in splash zone, apply abrasion (erosion) resistant FRCM system (Fibre Reinforced Cementitious Matrix) mainly on the upstream sides of pier highly prone to erosive forces. Step 7: Allow to cure and carryout an underwater (after repair and retrofit works) inspection with photography and videography of repair , all complete as per direction of Engineer-In-charge The rate is inclusive of all consumables, materials , labours , Tool tackles, Transportation , Lodging etc. involved.
