摘要
Abstract
This paper introduces the basic principle of high speed auger drilling technology and its advantages,and studies the influence of the rotational speed on spiral drilling discharge effect through the theoretical study.The technology is verified by field industrial test.The test results showed that drilling efficiency increased by 50.8％,hole-forming depth increased significantly by using high speed auger drilling technology in drilling construction.关键词
