PROBLEM TO BE SOLVED: To provide a pile head treating method of a cast-in-place pile and a pile head treating tool, capable of surely treating a pile head without requiring labor so much, by improving a surrounding environment of a construction site, including reduction in noise.;SOLUTION: A bar-shaped member 20, mutually superposed first plate member 31 and second plate members 32 and 33 and a third plate member 34 are embedded in a weld reinforcement part OH. After hardening concrete CN, tensional force FT is introduced to the bar-shaped member 20, and the second plate members 32 and 33 incline, and the first plate member 31 and the third plate member separate, and the weld reinforcement part OH can be removed in a crack CR part generated between the first plate member 31 and the third plate member. This constitution can largely reduce noise and vibration without requiring labor so much. In addition, since the crack CR direction is determined in response to an arranging attitude of a plurality of plate members 31 to 34, the crack direction of the concrete CN on pile head treatment is easily controlled, and the pile head treatment can be easily and surely performed.;COPYRIGHT: (C)2006,JPO&NCIPI
