ことを特徴とする砂杭造成用中空管。 A hollow pipe for constructing sand piles that is divided into upper and lower parts in the middle, the outer diameter of the upper pipe being smaller than the inner diameter of the lower pipe, and the inner surface of the lower pipe sliding on the outer periphery of the lower end of the upper pipe. The upper end of the lower pipe is provided with a flange capable of contacting the upper surface of the flange of the upper pipe, and the lower pipe is suspended by a wire different from the wire suspending the upper pipe. A hollow pipe for constructing sand piles, characterized in that it is configured to be able to be pulled up so that the lower pipe is stored from below.
