Construction method for evaluating corrosion resistance of reinforcing steel bars of reinforced concrete

The invention discloses a reinforced concrete reinforcement anti-corrosion evaluation construction method which comprises the following steps: S1, determining the flow direction and the flow speed of water seepage into a foundation pit according to the topographic condition of the foundation pit, and evaluating the water accumulation efficiency X of the foundation pit by utilizing the flow direction and the flow speed; s2, according to the interval construction period duration h during secondary concrete pouring of the foundation pit, the accumulated water depth L in the foundation pit is calculated, wherein L = X * h; s3, the corrosion grade is evaluated according to the accumulated water depth, the height of the concrete exposed out of the bottom of the foundation pit and the height of the steel bars exposed out of the concrete; carrying out anti-corrosion construction; and S4, during secondary concrete pouring, anti-corrosion parameters of anti-corrosion construction in the step S3 are ...
