Description of the Related Art Conventionally, in the investigation of the ground, which is an earth structure in the field of civil engineering and construction, soft rock materials are generally collected using a triple tube core tube or the like. After cutting the sample at the position to be tested, immediately set it on the lateral shaping device. Such a soft rock material is extremely sensitive to a change in the water content inside the sample, so it is important not to change the water content at the time of collection as much as possible. Therefore, for shaping the side surface and the end surface, it is necessary to take measures to suppress the change in water content at the time of sampling. The frozen soil is prepared by draining a sample in advance at the site, freezing it with dry ice, liquid nitrogen, or the like, bringing it into the room, and quickly preparing a specimen while it is not melted, and setting the specimen in a test apparatus.
