SMALL DIA. PILE AND CONSTRUCTURE METHOD FOR IT

摘要

PURPOSE: A small-diameter pile using a CFT is provided to increase frictional force between a steel pipe and mortar using a friction supporting and reinforcing unit. CONSTITUTION: A small-diameter pile using a CFT comprises a CFT pile(102) and friction supporting and reinforcing unit. The CFT pile is formed by filling a steel pipe with concrete. The friction supporting and reinforcing unit is attached on the outer surface of the CFT pile embedded in a rock layer. The friction supporting and reinforcing unit is composed of steel wires or reinforcing bars(103).
