Gravel compaction pile device using ball-type casing and gravel compaction pile method using the same

摘要

The present invention relates to a gravel compaction pile apparatus using a ball-type casing and a gravel compaction pile construction method using a ball-type casing, and more specifically described, By measuring the penetration length, the amount of reinforcing members inside the casing pipe, and the air pressure inside the casing pipe to maintain a constant air pressure inside the casing pipe, and by installing a ball casing pipe opened and closed by a ball at the bottom of the casing pipe, penetration When removing soil from the ground into the casing pipe, compaction is smoothly performed, and when the casing pipe is drawn to the upper part of the ground, the air pressure inside the casing pipe is appropriately adjusted to minimize disturbance of the ground around the upper part of the underground structure, and the casing pipe Gravel compaction pile device using a ball-type casing that improves work efficiency such as increasing construction quality and shortening construction period by forming a uniform and continuous underground structure by smoothly discharging the gravel underneath, and Disclosed is a technical field related to a gravel compaction file method using this.
