| Abstract: | With a project case of underground station, the pile foundations of existing buildings should be removed. It is of some advantages to use full-rotating equipment to clear underground obstacles such as little destructive effect for undisturbed soil and no disturbing the underground soil body. Then, several technical parameters and construction technologies about full-rotating equipment RT260H are presented including the procedure, steel thimbles drilling, removing the piles and backfilling, etc. |
