How should rust at the bottom of the tower foot flange be dealt with?
Thread Content
The portion of the communication tower (single-tube tower) below the base flange was not poured during the initial construction phase, which has led to severe rusting. What should be done now?
It’s shot too locally! You can first remove the rust, then mix oil with butter and apply it on top
Use a machine tool rust remover to remove rust, then apply a rust inhibitor for protection; follow the method suggested by the person upstairs, and it’s best to seal it off as well.
It is necessary to remove all the rust completely, identify the cause of the rusting, and then take measures to prevent further rusting based on that cause (apply butter and then cover it up). . ）
Use a hammer to strike it and see if it breaks; it seems to be quite rusted. If it can be replaced, do so – don’t worry about the complexity of the work; any problem that arises is serious. If it can’t be replaced, polish it clean, apply butter for reinforcement, and install guards around it
Use a grinder to remove rust, then apply anti-corrosion paint
The surface layer has been oxidized, but the interior should still retain its strength. Since the space available isn’t large, sandblasting for rust removal could be tried. Recently, I’ve also come across strong adhesives and fixatives that can be used right after the surface is polished; these can be applied to fasten the bolts to the concrete, serving both to reinforce it and to prevent corrosion
Check the specific degree of corrosion of the bolts; if there is too much, they need to be replaced. Also, the strength needs to be protected through rust removal, corrosion prevention, and sealing! All of them are essential!
