PILE DRIVING MACHINE AND CONSTRUCTION PROCESS OF FOUNDATION PILE

摘要

The present invention relates to a pile foundation construction method for constructing piles on a foundation layer to solidify the foundations of various buildings such as high-rise buildings, and more particularly to a pile foundation construction method for forming pile excavation holes with a trowel screw- After the cement paste is injected to the bottom of the excavation hole, the pile wall is consolidated and the file with the pile end member is rotated by the pile rotation auger to pile the pile end member attached to the pile to the bottom of the excavation hole, The auger 110 for compacting excavation equipped with a tiller screw and installed in a pile driver in a pile foundation construction method for use as a building foundation foundation, And a pile driving auger 12 in addition to the auger 110 for compacting excavation The cement paste is charged into the excavation hole 170 while driving the auger for consolidation drilling after the excavation hole 170 for compacting the file is excavated by the burr 100 and the pile end member 160 and the hook 152 are attached to a rotary cap provided in the file rotation auger 120 and the file is rotationally press-fitted so as to seat the file up to the support layer so that the file construction is robust and the support force is high It is possible to build a sturdy building, prevent vibration and noise due to impact, prevent environmental damage such as dust, and provide file-based construction which can speed up construction cost and construction period. A construction method and a device therefor.
