Abstract
In view of the water gushing phenomenon en-countered during a gas pipeline horizontal directional drilling crossing water-rich mountain in Beijing,the grouting leak-stoppage technology for horizontal direc-tional drilling crossing water-rich mountain was devel-oped,which achieved good leak-stoppage effect.The groundwater of water-rich mountain is mainly the bed-rock fissure water.According to the situation of the ex-ploration hole,the position of the water outlet point is determined,and the grouting packer is sent to the pre-determined position in the guide hole for seat sealing.The grouting material is injected into the blocked guide hole with the pressure higher than the bedrock fissure water,so that the grouting material fills the bed-rock fissure of the water-rich mountain.After the final solidification of the grouting material,the bedrock fis-sure can be sealed and the leak can be stopped.关键词
