摘要
Abstract
During the engineering investigation made for the ground powerhouse of Dahuaqiao Hydropower Station on Lancang River, the in-hole drill blocking accident happened due to the complicated geological condition therein and it can not be treated with the relevant traditional treatment method, therefore, the technology of the multi-casting drilling is applied after the analysis and study concerned. With this technology, the defect of the traditional method can be avoided and then the blocking accident can be successfully treated as well. The application of the multi-casting drilling technology to the field of drilling engineering can improve the overall level of the drilling technique, and then has a higher value for application and popularization.关键词
