9 Simple Techniques For Bridge Lifting And Replacement of Bearing - Shivam Concrete
Reinforcement and using corrosion protective chemical: If old bearing pedestal is to be rehabilitated, the broken surface area shall be completely cleaned up by wire brush to eliminate loose rust particles then exposed support will be cleaned of all rust and millscale by mechanical wire brush, to removal of oil or greasy residues and also the loss of support shall be compensated by connecting of new reinforcement.
The reinforcement's rust, if any, shall be eliminated by using rust removal, chemical (Reebaklens RR of Fosroc or comparable item of BASF or Sika) and cleansing of reinforcement with a mechanical wire brush. After that using one coat of zinc rich finishing of Nitozinc Guide of Fosroc or comparable item of BASF or Sika).
Micro-concrete: Flowable mix of 1part by weight of Micro-concrete power, 1 part by weight of grit/Aggregate (approximately 10mm) and essential water required for workability. The mix will be combined completely by mechanical stirred for about 3 mins. D. Using: After supplying required water tight shuttering, the flowable mix must be poured and there is no requirement for compaction as it is flowable and self compacting mix.

So after installation of POT-PTFE bearings, You need to take note of detach the temporary clamp. 3. In case of metal bearings, dirt, rust and corrosion are typical remedies due to weather impact. For Bearing rust elimination and Cleaning/repainting: The following stepwise treatment is to be followed: A. The area around the bearings and their pedestals shall be cleared of all debris, plant life, dust, and so on.
B. Fresh graphite grease as approved by the Engineer will be used to the surfaces which are siding, rotating or moving due to movement in bearings. C. All other surface areas of the metal bearing shall be cleaned up of all rusts, corrosion and a coat of anticorrosive oil paint applied.
