The invention discloses a prefabricated tubular pile implanting device and pile implanting construction method. The prefabricated tubular pile implanting device comprises a drilling tool assembly, a drilling machine body with a drilling mast and a power head assembly arranged on the drilling mast in a sliding mode. The power head assembly comprises an upper power head and a lower power head. The upper power head is provided with a first vertical channel allowing the drilling tool assembly to penetrate through. The upper power head is provided with a first enclasping mechanism used for enclasping or loosening drill rods. The lower power head is provided with a second vertical channel allowing a precast pile to extend in and allowing the drilling tool assembly to penetrate through, and the lower power head is provided with a second enclasping mechanism used for enclasping or loosening the precast pile. The top of the drilling mast is connected with a crane used for hoisting the drillingtool assembly, and the crane can horizontally rotate relative to the drilling mast. The drill rods can penetrate through the upper power head, the lower power head and the precast pile to be lengthened after being hoisted by the crane, and the two drill rods to be lengthened can be ensured to be coaxially arranged all the time in the lengthening process through limiting and supporting of the powerheads, so that lengthening construction is convenient, fast, efficient and high in safety.
Description
technical field [0001] The invention relates to the technical field of pile foundation construction, in particular to a device for implanting prefabricated tubular piles and a construction method for planting piles. Background technique [0002] The tube-and-drilling method is a mid-digging pile-sinking method. During the construction, the long auger drill rod equipped with the drill bit with the hole reaming function is passed through the prefabricated pipe pile, and the soil is excavated at the bottom of the prefabricated pipe pile to form a hole. When drilling is required, the power head rotates forward, the reaming flange of the reaming drill bit opens, the drill bit rotates a certain distance below the bottom of the prefabricated pipe pile to excavate the soil, and the drilling slag is conveyed by the blade of the auger drill pipe and discharged from the pipe pile hole. The prefabricated pipe pile sinks by its own weight following the drill bit. If during the pile sin...
