摘要

PURPOSE: A construction method for a micro pile using a pack and a pile assembly using the same are provided to obtain a required strength without hoarding an outer casing after construction is completed. CONSTITUTION: A pile assembly(100) and a construction method of a micro pile using a pack comprises a pipe(110) and a pack(120). The pipe has multiple injection material discharge holes. The injection material discharge holes are formed in a soft layer(2) of ground and are vertically separated from each other. The pack is installed by covering the pipe, located in the soft layer, so that the pack is expanded by an injection material injected through the injection material discharge holes.
