Yellow River caverns penetrated East Route of South-to-North Water Diversion Project. They crossed the Yellow River in the rock formations at a depth of 70m below the water surface of the Yellow River. Karst development occurred in the project area and Sanshui (Yellow River water, overburden diving and karst groundwater) Completed in January. On the morning of August 30, 1999, during the daily drainage operation, it was found that the gushing water in the northern side of the pump house in the cavern watercourse was successfully sealed by the grouting and blocking measures by drilling grouting.
