<p>Disclosed is a replaceable drainage device of an expansion joint. Fasteners are fitted into fixed bearings installed on opposite sides of an expansion space between slabs or on bottom surfaces of the slabs, and an expansion member is coupled to the fasteners in the expansion space in a "U" shape. Thereby, a waterproofing function is remarkably improved by preventing water from leaking from a coupled part of the expansion member and the fixed bearings, and a bridge is allowed to maintain durability. When the expansion member should be replaced due to deterioration, only the expansion member is pushed into or pulled from the fixed bearings on one side of the bridge. Thereby, the replacement work is easily performed, and the maintenance and management of the bridge are economically preformed. To this end, the expansion joint's replaceable drainage device, which is installed between upper slabs of a bridge, is characterized in that: a pair of fixed bearings having fixing recesses are buried in the slabs on opposite sides of the slabs; a fastener is fitted into each fixing recess; opposite ends of an expansion member are coupled into the fasteners, respectively; and the expansion member is installed in an expansion space between the slabs in a "U" shape, thereby preventing leakage of water.</p> |
