CONSTRUCTING METHOD FOR FOUNDATION PILE

摘要

PURPOSE: A preboring method of a small diameter foundation pile is provided to increase shear resistance by partially forming a reamed hole an inner wall of an embedded hole, filling concrete inside the reamed hole, and forming a shear protrusion. CONSTITUTION: A preboring method of a small diameter foundation pile comprises as follows. An embedded hole is excavated on the ground. A reaming bit is put into the embedded hole, and the partial embedded hole is formed on an inner wall of the embedded hole through reaming by the reaming bit. After the foundation pile is embedded into the embedded hole, concrete is placed and cured. The foundation pile includes a pile main body and a wing member.
