PURPOSE: A method for constructing a small diameter casing pile is provided to guarantee safety against differential settlement, and to reduce noises using small equipment. CONSTITUTION: A method for constructing a small diameter casing pile comprises following steps. A borehole(100) is formed up to a bed rock layer by a small-diameter perforator. A grouting hose is attached to the inner and outer walls of a high-strength casing(110). A casing is inserted into the borehole by a coupler(120) for connecting a casing. High-strength grouting(150) is placed into the inside and outside of the casing through the grouting hose. [Reference numerals] (AA) Soil; (BB) Bedrock |
