| Abstract: | Testing researchers of guided-boring technology have been carried out in megalithic and coarse-sand see reclamation using different pneumatic down-the-hole hammers. Problems facing H-type pile submergence in the second-stage foundation works of Shenzhen Mawan Electric Power Plant has been successfully solved. This paper analysis pneumatic down-the-hole hammer technology and tool utilization, and suggests improving steps of technology during utilization of pneumatic down-the-hole hammer. |
