Abstract

The invention provides a guide hole type static pile driver. The guide hole type static pile driver comprises a static pile driver, a side pile and guide hole equipment, the hole guiding equipment comprises a hole guiding base and a hole guiding mechanism, the hole guiding base is installed on the static pile driver, the hole guiding mechanism is detachably installed on the hole guiding base, the hole guiding base is at least provided with a first installation position and a second installation position, and when the hole guiding mechanism is installed at the first installation position, the hole guiding mechanism corresponds to a pile pressing mechanism of the static pile driver. The hole guiding mechanism is arranged corresponding to the pile pressing mechanism of the side pile when being mounted at the second mounting position; the hole guiding mechanism comprises a hole guiding device and a spiral drill rod, the spiral drill rod is installed on the hole guiding device, the hole guiding device is used for driving the spiral drill rod to rotate, and the maximum diameter of the spiral drill rod is smaller than the diameter of the inner ring of the prefabricated pipe pile. Meanwhile, the invention further provides a construction method of the guide hole type static pile driver. Compared with the prior art, the guide hole type static pile driver and the construction method thereof can better guarantee the construction quality of the prefabricated pipe pile.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a lead hole type static pile driver and a construction method of the lead hole type static pile driver. Background technique [0002] At present, for the construction of prefabricated pipe piles with a diameter of 600mm and above in complex strata such as thick sand layers, quicksand layers, and hard interlayers, the construction method of hydraulic hammer hammering or the construction method of drilling first and then static pressure is usually used. [0003] Among them, the hydraulic hammer is used for the construction method. Due to the poor penetration ability of the prefabricated pipe piles, there are problems such as high noise, easy cracking of the pile body, and pile breakage during construction. However, the construction method of rotary drilling first and then static pressure has the problems of complicated procedures, high cost, long construction period,...
