SLEEVE EXPANSION JOINT AND THE CONSTRUCTION METHOD THEREFOR
The present invention relates to a sleeve expansion joint capable of being replaced and easily installed, and to a construction method thereof wherein the sleeve expansion joint absorbs a displacement caused by the expansion and contraction of a concrete slab for a railroad with or without a ballast. The sleeve expansion joint comprises: an expansion member; a fixing frame; a fixing block; a buried supporting frame; and a shear bolt. The present invention has an advantage maintaining and managing quality as expansion and contraction caused by a temperature change or the like of the slabs is offset by the expansion and contraction member installed in a gap between the slabs; the sleeve expansion joint rapidly installed and released; and guided drainage facilitated by a gradient.
