PURPOSE:To perform simple and rapid execution, by a method wherein a ground is excavated down to a portion having serious corrosion, a quick curable reinforcing cement solution is poured in the excavated hole for solidifying, a portion, exposed to a ground surface, is contained in a protection cylinder, and a cement solution is poured into the cylinder for solidifying. CONSTITUTION:An excavated hole 5 is excavated about 50cm deep from a ground surface where the degree of corrosion of a support rod 4 of an anchor block 3 is high, and the excavated fole is filled with gravel 6 up to a level located about 10cm down from the ground surface. A quick curable reinforcing cement solution is poured into the hole 5, and a protecting cylinder 1 is inserted outwardly of a support rod 4 to anchor it to the gravel 6 before coagulation and solidification are started to secure the protecting cylinder 1 to first concrete 7. Thereafter, the quick curable reinforcing cement solution is poured in the protecting cylinder 1 for solidification to form secondary concrete 8. |
