Abstract:According to the difficulties for rotary drilling rig in large diameter rock-socketed pile construction in hard rocks, cluster DTH hammer is matched as the solution. JSQ-Z positive circulation and JSQ-F reverse circulation cluster DTH hammers were designed, 3 kinds of construction methods and drilling tools matching scheme are presented, which makes large diameter rotary drilling in hard rocks more rapid, efficient and economical. |
