ことができた。<Effects> The present invention is equipped with a coupling fixed to the central part of the pile pipe, and a lifting cylinder that is erected on the top of the pedestal, with a hook for hooking the weight being tiltable at the tip of the rod via a mounting bracket. A tilting member is fixed to a pile pipe located above the tilting member, and a weight that falls when the claw is detached is slid onto a portion of the pile pipe between the claw that collides with the tilting member and tilts, and the coupler spring. By providing a detection part which can be freely installed and which detects the number of strikes by the collision of the weight falling on the top surface of the mount below the weight, by moving the cylinder, the rod extends upward and the tip of the rod. The weight is lifted by the above-mentioned claw provided through the mounting bracket, and the claw collides with the tilting member above, causing the claw to separate from the weight, causing the weight to slide into the pile pipe and fall. The lower surface of the weight collides with the upper surface of the coupling, causing the tip of the pile tube to advance into the floor surface, and as the tip of the pile tube enters the floor to a certain depth, the detection unit detects the number of collisions with the coupling caused by the falling weight. To provide a ground penetration testing machine capable of accurately detecting the amount of driving of a pile into a foundation floor surface, without causing the tip of the pile to stick to the foundation floor surface and move as in the past. I was able to do that.
