In 2015, Laos Nam Lik 1-2 power station once dealt with the defect of the flood discharge tunnel. After the flood discharge hole was emptied in 2018, it was found that the concrete was peeled off and exposed. After on-site census, radar detection, rebound and core strength testing, it is judged that the tunnel has apparent defects but does not affect the flood season operation. In order to prevent the surface concrete from being washed by the water flow and continue to expand the shedding surface, it can be repaired and strengthened after the flood season, which provides a favorable scientific basis for the operator.
