Prefabricated tubular pile implanting equipment and pile implanting construction method
The invention discloses prefabricated tubular pile implanting equipment and a pile implanting construction method. The prefabricated tubular pile implanting equipment comprises a drilling machine bodyand a drilling tool assembly, a drilling mast is fixed to the drilling machine body, and an upper power head used for driving the drilling tool assembly to conduct rotary drilling and a lower power head used for driving a precast pile to sink are arranged on the drilling mast in a sliding mode; the upper power head is provided with a first vertical channel allowing the drilling tool assembly to penetrate through, and the upper power head is provided with a first holding mechanism used for holding or loosening the drilling tool assembly. A second vertical channel allowing the precast pile andthe drilling tool assembly to penetrate through is formed in the lower power head, and a second holding mechanism used for holding or loosening the precast pile is arranged on the lower power head. Due to the fact that the drilling tool assembly can penetrate through the upper power head, the drilling tool assembly can be lifted to the position between the drilling tool assembly and a foundation through a lifting device to form a containing space of the precast pile, and the precast pile can be conveniently positioned. Therefore, when multiple sections of precast piles at the same pile position or precast piles at different pile positions are positioned, the drilling tool assembly does not need to be disassembled and then assembled, and the construction efficiency is greatly improved.
本发明公开了一种预制管桩植入设备及植桩施工方法，装置包括钻机主体和钻具总成，钻机主体上固定有钻桅，钻桅上滑设有用于驱动钻具总成旋转钻进的上动力头，用于驱动预制桩下沉的下动力头；上动力头上开设有可供钻具总成穿过的第一竖向通道，上动力头上设有用于抱紧或松开钻具总成的第一抱紧机构；下动力头上开设有可供预制桩和钻具总成穿过的第二竖向通道，下动力头上设有用于抱紧或松开预制桩的第二抱紧机构。由于钻具总成可贯穿上动力头，从而可通过起吊设备将钻具总成提升至钻具总成与地基之间形成预制桩的放置空间，以便于预制桩的定位。因此，同一桩位多节预制桩或不同桩位预制桩定位时，无需拆卸再组装钻具总成，大大提高了施工效率。
