Comparative Analysis of Pore Formed with Percusive Reverse Circulation Drill and Percussion Drill |
| |
| Abstract: | According to the geological conditions of Zhujiang cable-stayed bridge in Chaoyang,the pore forming technology with percussive reverse circulation drill and conventional percussion drill is analyzed and compared from aspects of pore-forming time,slurry amount and pore-forming cost.It is proposed that percussive reverse circulation drill is preferred for pore-forming under the similar geological conditions. |
