The Applications of Bored Pile Drilling Tech. in Large Floating Rock in Changchun Light Rail Project

Abstract:

The drilling principle, down-the-hole hammer drilling technique, core dynamite technology about accumulating capacity and cutting rock technology about tubular drill are introduced, taking bored pile construction of light track inclined bridge engineering in Changchun as a sample. Efficient methods of drilling hole and making pile for the large floating rock have been sum up.
