Repairing defective concrete elements of the\nbridge. Then lift the concrete bridge to change the deformed bearings.<\/h2>\n\n\n\n\n

Added Value to the Customer:<\/h2>\n

\u00b7<\/span> Detailed work methodology to represent the work stages and the\ndetails of the steps for each phase.<\/p>\n

\u00b7<\/span> Calculate the Bridge loads and determine the exact location for\neach lifting point.<\/p>\n

\u00b7<\/span> Provide risk assessment and safety precautions for the every\nphase of the process.<\/p>\n\n\n\n\n

Engineering Concept:<\/h2>\n

As a result of a major fire broke out in part of the King Salman Axis Bridge (Al-Zumar Axis) on the Ring Road, Which led to damage to parts of the concrete bridge, exactly some of the main bridge’s\ncolumns, column\u2019s caps, and the bottom of some concrete beams as well. In\naddition to the damage of the bearings of the bridge above these columns.<\/p>\n

The solution was to repair the damaged parts\nfirst and renew them completely, after that the process of lifting the bridge\nstarted to change, and replacing the damaged bearings with new ones.<\/p>\n\n\n\n\n

Fast Track Solution:<\/h2>\n

1st Phase: Repairing defective concrete elements of the bridge:-<\/p>\n

\u00b7 <\/span>First, we removed and scraped all the burnt and damaged plaster\nand paint from the surface of the concrete elements.<\/span><\/p>\n

\u00b7 <\/span>After that, we removed the concrete cover of the elements and\nexposed the reinforcement rebar. And we cleaned the uncovered surfaces using\nspecial liquids.<\/span><\/p>\n

\u00b7 <\/span>We carried out the process of perforating the concrete elements\nand preparing them for the planting process of new reinforcing bars using\nbonding epoxies according to the consultant\u2019s recommendations and the standard\nspecifications. Then we recast it using a special concrete mix.<\/span><\/p>\n

\u00b7 <\/span>Finally, we began plastering and painting work to complete the\nrenovation phase of these concrete elements.<\/p>\n

2nd<\/sup> Phase: lift and replace the bridge\u2019s bearings:-<\/p>\n

\u00b7 <\/span>Based on the bridge loads and our calculations and drawings we\ndetermined the lifting points and the required number of the Hydraulic Lifting\nJacks.<\/p>\n

\u00b7 <\/span>We placed the jacks at the lifting points, then we started to lift\nthe bridge until we reached the required height.<\/p>\n

\u00b7 <\/span>Now, we freed the defected bearings and our skilled labors\nreplaced all of them by the new ones.<\/p>\n\n\n\n\n
