Combined Application of Steel Casing by Vibrating Hammer and Rotary Drilling Rig

Abstract:

Advantages of vibrating hammer were brought into play while sinking steel supporting tube by vibrating hammer combining with rotary drilling rig in different construction environments and pile types, such as piling on land, in and under water, pile pulling, caisson, underground seepage wall and soil compaction in soft ground. And high velocity of rotary drilling rig was also fully played. It provided the reference for rotary drilling rig construction in similar ground.
