PROBLEM TO BE SOLVED: To provide a tremie pipe for easily connecting to another tremie pipe in a disengageable way in either circumferential or connecting direction, and to provide a connecting structure of the same.;SOLUTION: The tremie pipe has a circumferential groove part 6, which a connector 5 made of a flexible rod-like body can be freely inserted into and removed from, formed on the outer-wall surface of a small-diameter fitting part 4 in one end part. Also, a circumferential groove part 10, which the connector 5 can be freely inserted into and removed from, is formed in the inner-wall surface of a large-diameter fitting part 9 in the other end part. An opening part 11 communicating with the groove part 10 in the inner-wall surface is opened in the outer-wall surface of the large-diameter fitting part 9, so that a plurality of the tremie pipes 1 are connected to one another to be in a prescribed length. Further, the tremie pipe has a notch groove 3 formed in an open-end part 9a of the large-diameter fitting part 9, and also an engaging protrusion part 2 to protruded from the outer-wall surface 4a of the small-diameter fitting part 4 to be engaged with the notch groove 3, and thereby obtaining the connecting structure of the same.;COPYRIGHT: (C)2011,JPO&INPIT
