To provide an underground sampling tool installable in a tip bit part without removing the tip bit part of an excavator, reducing cost with a simple structure, capable of sampling even a sample of any depth in the ground, and capable of easily agitating soil cement again.
This sampling tool has a sampling pipe 10 having a tubular part 12 and an orifice part 14, a cover body 16 for blocking up an opening part of the orifice part, and an installing part 30 for installing the sampling pipe on an agitating blade or an excavating blade of the tip bit part of the excavator. The installing part is formed in substantially parallel between a shaft of the sampling pipe and a surface of the agitating blade or the excavating blade, and installs the sampling pipe on the agitating blade or the excavating blade so as to become substantially orthogonal between the shaft of the sampling pipe and a diameter of the tip bit part of the excavator. The cover body opens when the tip bit part of the excavator normally rotates in the ground, and closes when the tip bit part reversely rotates.
