System for enhancing bearing power of soft ground using hardening pile reinforced with public works textile pack and construction method thereof

摘要

PURPOSE: A construction method of an enlargement system for bearing force of the soft ground using a compaction pile reinforced by a geosynthetic pack is provided to enhance the bearing force of the soft ground and to reduce the period and cost of construction. CONSTITUTION: The construction method of an enlargement system for bearing force of the soft ground using a compaction pile reinforced by a geosynthetic pack comprises the steps of: installing a barge on a job site and installing sand boxes(23) on the side of the barge; closing up a double operator installed on the lower end using a vibration presser(21) installed on the barge, then pressurizing a steel pipe and installing a compaction pile(11); interposing a geosynthetic pack into the steel pipe to prevent the leakage of filler and to keep the shape of a compaction pile; placing one of sands, gravels and broken gravels in the geosynthetic pack using a back hoe(20) installed on the barge; dismantling a double operator installed on the lower end of the steel pipe interposed to the ground using regular vibration using a vibration presser(21) installed on the barge, then taking off and compacting fillers placed in the geosynthetic pack to form a compaction pile(11); and paving a mat stiffener on the upper part of a sand pavement layer placed on the compaction pile(11), then installing a structure.
