摘要

PROBLEM TO BE SOLVED: To provide a cap for pile head treatment easily mountable on the top of a double reinforcement cage formed of cylindrical cage-like inner reinforcement tube and outer reinforcement tube in a short period of time and a method of mounting the cap for pile head treatment on the top of the double reinforcement cage.;SOLUTION: This cap 1 for pile head treatment mounted on the top of the double reinforcement cage comprises at least the inner reinforcement tube 3 for introducing a tremie tube therein, the outer reinforcement tube 4 having a diameter larger than that of the inner reinforcement tube 3, and an upper plate 7 and a bottom plate 8 having holes 5, 6 for passing the tremie tube therethrough. The upper plate 7 comprises an air vent hole 13. The bottom plate 8 comprises a plurality of cut openings 15 formed on the inside at a predetermined interval from the peripheral edge 14 around the hole 6 through which the center tremie tube passes, a plurality of round holes 18 (or elongated holes) in which the main reinforcements of the outer reinforcement tube of the double reinforcement cage are inserted on the same circumference, and elongated holes 19 in which the main reinforcements of the inner reinforcement tube are inserted on the same circumference.;COPYRIGHT: (C)2007,JPO&INPIT
