NEUTRALIZATION TREATMENT METHOD FOR ROCK-FILL EMBANKMENT PRODUCING ACID DRAINAGE

摘要

The present invention relates to a method for treating acid drainage in the case of acid drainage in the embankment piled up to form roads, railways, and slopes. In the present invention, first, electric exploration is performed on the fill body to detect a risk area with a high probability of acid drainage in the fill body, drilling the risk area to collect a sample, and analyzing the probability of acid drainage occurrence of the sample. According to the result of the probability analysis, injection holes are formed in the hazardous area, a neutralizing coating agent and cement slurry are injected to coat the surface of pyrite, and acid drainage and acidic areas are neutralized.
