Deep replacement dynamic compaction gravel pile foundation reinforcement method
The invention discloses a deep replacement dynamic compaction gravel pile foundation reinforcement method. The method includes the following steps that firstly, a pile pipe (5) of a pile machine is aligned with a pile toe (6) in place at a pile position; secondly, a vibrating hammer (3) of the pile machine is started and vibrates to conduct countersinking operation downwards; thirdly, a hopper (1) of the pile machine is used for conducting filling for the first time from a feed port (4); fourthly, the pile pipe (5) of the pile machine ascends, dynamic compaction broaching is conducted, and a dynamic compaction gravel mound is formed; fifthly, the hopper (1) is used for conducting supplementary filling from the feed port (4); sixthly, the fourth step and the fifth step are repeated till the dynamic compaction gravel mound reaches pile tip elevation. Dynamic compaction energy can be effectively led to the foundation deep position through the pile pipe, the defects of the replacement dynamic compaction construction process and the vibration gravel pile process are overcome, quality is high, benefits are good, the construction period is short, and the foundation reinforcement effect is better.
