SCREW ANCHOR PILE FOR EARTH REINFORCEMENT

摘要

PURPOSE: A screw pile for a tension member for ground reinforcement is provided to cost-efficiently produce the screw pile by optimizing the size of the screw pile. CONSTITUTION: A screw pile for a tension member for ground reinforcement is composed as follows. Screw blades(20) are continuously formed on the outer surface of a circular steel bar(10) in a spiral shape to be inserted into the ground. The pitch(P) of the screw blades is 2.0-2.5 times larger than the diameter(d) of the circular steel bar. The diameter(D) of the screw blades is 1.5-2.0 times larger than the diameter of the circular steel bar.
