Foundation treatment vibration densification device and vibration densification method for aeolian sand stratum
The invention discloses a foundation treatment vibration densification device and vibration densification method for an aeolian sand stratum. The foundation treatment vibration densification device comprises a bottom plate provided with a compression roller, the bottom plate is provided with a counterweight and a first hydraulic cylinder connected with a compaction mechanism, the first hydraulic cylinder can drive the compaction mechanism to reciprocate, a support is arranged on the compacting mechanism, a top plate is arranged on the top of the support, a vibration densification mechanism is arranged on the top plate, a lifting mechanism is arranged in the vibration densification mechanism, and a hollow vibration tamping pipe with through holes in the side wall of the hollow vibration tamping pipe is installed on the lifting mechanism; the vibrating densification device is pushed to the position beside liquefied accumulated sand, the vibration tamping pipe is located above the liquefied accumulated sand, the rotating vibration tamping pipe is sunk into the liquefied accumulated sand at the same time, vibration is reserved, the vibration tamping pipe is lifted up by a certain distance, then the vibration is reserved till the vibration tamping pipe is completely lifted up, the compacting mechanism is located above the liquefied accumulated sand subjected to vibration densification, and compacting is conducted. According to the foundation treatment vibration densification device, manual handheld vibration densification is not needed, vibration densification and beating compaction are integrated, the working efficiency is improved, and holes can be prevented from being formed in the liquefied accumulated sand subjected to the vibration densification.
本发明公开了一种用于风积沙地层的地基处理振密装置及振密方法，该装置包括安装有压辊的底板，底板上设有配重和与排实机构相连接的第一液压缸，第一液压缸可驱动排实机构往复移动；排实机构上设有支架，支架顶部设有顶板，顶板上设有振密机构，振密机构中有升降机构，该升降机构上安装有中空的侧壁上有通孔的振捣管。将振密装置推至液化积沙旁，使振捣管位于液化积沙上方，将旋转的振捣管同时沉入液化积沙，留振，上提一段距离再留振，直至振捣管完全上提，使排实机构位于振密后的液化积沙上方，进行排实。该振密装置无需人工手持振密，且集振密、拍打紧实于一体，提高工作效率，且能避免在振密后的液化积沙中形成孔洞。
