Abstract
To repair reinforced concrete easily and at low cost. An anticorrosion method includes infiltrating an anticorrosion solution held inside concrete of reinforced concrete into a vicinity of a reinforcing bar through the concrete to passivate the reinforcing bar, detecting that the anticorrosion solution is infiltrated to a surface of the concrete, and discharging, after detecting the anticorrosion solution, the anticorrosion solution to outside of the concrete to form an anticorrosive coating on a surface of the reinforcing bar.
Claims19
An anticorrosion method for suppressing corrosion of a reinforcing bar in reinforced concrete, the method comprising:
- infiltrating an anticorrosion solution a vicinity of the reinforcing bar through the concrete to passivate the reinforcing bar, wherein the anticorrosion solution is held in a storage unit formed by the concrete and disposed inside the concrete;
- detecting that the anticorrosion solution is infiltrated to an outside surface of the concrete;
- and
- discharging, after detecting the anticorrosion solution, the anticorrosion solution remaining in the storage unit to outside of the concrete to form an anticorrosive coating on a surface of the reinforcing bar.
An anticorrosion device configured to suppress corrosion of a reinforcing bar in reinforced concrete, comprising:
- a storage unit formed inside concrete of the reinforced concrete and formed by the concrete, wherein the storage unit is configured to hold an anticorrosion solution;
- a detection unit configured to detect that the anticorrosion solution is infiltrated to an outside surface of the concrete;
- and
- a drainage unit configured to discharge, after detection of the anticorrosion solution by the detection unit, the anticorrosion solution remaining in the storage unit from the storage unit, wherein
- the anticorrosion solution includes a solution that infiltrates into a vicinity of the reinforcing bar through the concrete to passivate the reinforcing bar and forms an anticorrosive coating on a surface of the reinforcing bar.
An anticorrosion device configured to suppress corrosion of a reinforcing bar in reinforced concrete, comprising:
- a storage unit formed inside concrete of the reinforced concrete and formed by the concrete, storage unit is configured to hold an anticorrosion solution;
- and
- a drainage unit configured to discharge the anticorrosion solution from the storage unit, wherein
- the anticorrosion solution includes a solution that infiltrates into a vicinity of the reinforcing bar through the concrete to passivate the reinforcing bar and forms an anticorrosive coating on a surface of the reinforcing bar, and
- the drainage unit is formed of an identical concrete as the concrete, wherein a thickness of the drainage unit is not less than a thickness of the concrete between the storage unit and the reinforcing bar, and less than a thickness of the concrete between the storage unit, through the reinforcing bar, and an outside surface of the concrete.
