PAN HUALIN / WANG XUETAO / ZHANG BAOLONG / HONG YI / WANG LIZHONG

The invention discloses a large-diameter pile rapid sinking device which is used for rapidly sinking a large-diameter pile and comprises a base, a pile top propelling device, a pile side hydraulic linkage device, a servo water injection system and a CPTu geological detection system, and the pile top propelling device and the pile side hydraulic linkage device are both installed on the base; the upper portion of the large-diameter pile is connected with the pile top propelling device, and lifting of the large-diameter pile is achieved through the pile top propelling device. The lower portion of the large-diameter pile is connected with the pile side hydraulic linkage device, and lateral fixing of the large-diameter pile is achieved through the pile side hydraulic linkage device. The servo water injection system and the pile side hydraulic linkage device are connected and are respectively used for injecting pressure and adding water; and the CPTu geological detection system is carried on the pile side hydraulic linkage device and is used for carrying out soil property testing and in-situ exploration on an in-situ geological seabed.
