The entering-rock problem of pouring pile through large-diameter hole drilling is always the biggest difficult problem in the fundamental construction of Guangxi. Recently the Guangxi First Geological Engineering Construction Company introduces the percussive reverse drilling method, and has made a great breakthrough. This article with successful engineering example emphatically introduces the method, mostly the drilling principle, hole completion technology, selection of technologic parameters, accident prevention and handling, and contrary and analysis of technological and economical indices and so on. Persons of same occupation can use drilling method for reference.
