To provide a tremie tube and a connection structure thereof that prevent catching on a core material when pulled out.SOLUTION: A tremie tube is obtained by fixing a hollow tubular female joint having a larger diameter than a hollow tubular body to one end of the hollow tubular body having a predetermined tube diameter and length, and fixing a hollow tubular male joint having a large diameter portion larger in diameter than the hollow tubular body to the other end of the hollow tubular body. In the tremie tube, a guide slope is formed which is inclined from an end of an outer peripheral surface of the large diameter portion of the male joint toward an outer peripheral surface of the hollow tubular body in a direction of the female joint, and an upward step difference caused by a difference between the large diameter portion of the male joint and the tube diameter of the hollow tube body is eliminated.SELECTED DRAWING: Figure 13
【課題】引き抜き時における芯材への引っ掛かりを防止するトレミー管及びその連結構造を提供する。【解決手段】所定の管径と長さ寸法を有する中空管体の一端に、中空管体より径大の中空筒状の雌ジョイントを固着するとともに、中空管体の他端に、中空管体より径大の径大部を有する中空筒状の雄ジョイントを固着してなるトレミー管において、雄ジョイントの径大部の外周面端部から雌ジョイント方向の中空管体の外周面に向けて傾斜したガイドスロープ面を形成し、雄ジョイントの径大部と中空管体の管径の差に起因する上向段差を解消したトレミー管を提供する。【選択図】図１３
