摘要
By the construction technology combination of rotary drilling rig and positive circulation percussive drilling, these two technologies took full advantages of fast construction speed in soil and rock, and the traditional rock-socket pile construction process was broken. Based on the successful case of hole completion in a pile foundation construction, this paper introduced these two technologies on the technical measures and the attentions.
