END SHOE APPARATUS OF STEEL PIPE PILE FOR ENLARGING EFFECTIVE SECTION FOR IMPROVING END BEARING CAPACITY WITHOUT INCREASING EMBEDMENT DEPTH

摘要

PURPOSE: An end shoe apparatus of a steel pipe pile for enlarging the effective section is provided to increase the supporting force of the end by mounting the shoe apparatus in the end of the steel pipe pile, and to improve friction force by restricting disturbance of earth and sand of the ground. CONSTITUTION: An end shoe apparatus of a steel pipe pile(1) is composed of a horizontal blocking member(10) formed of a round edge type provided with an inlet(13) for inputting the ground in driving the steel pipe pile into the ground and installed in the opening end of the steel pipe pile to enlarge the effective sectional area by reducing the opening section of the steel pipe pile, and a reinforcing steel member(30) extended from the upper part of the horizontal blocking member along the inner periphery of the steel pipe pile and spaced from the steel pipe pile to keep or increase the effective sectional area of the steel pipe pile.
