Abstract Curtain grouting is an effective way to block the water coming from fault, which is characterized by high technical standard, complex construction technology, long construction period and high cost. The effect of water blocking will be affected if it is not cautious enough during the implementation of curtain grouting, even resulting in rework of water blocking. The construction technology of curtain grouting is presented in detail by taking the practice of water blocking taken in F9 fault of Qingyun tunnel on Xiangtiang-Putian railway. The test of grouting effect shows that the grout filling is full and the water seepage from single bore complies with the designed requirement.
