The present invention relates to an adapter that is installed on a self-assembly PC power cable tunnel and an underground power distribution manhole, which can resist hydraulic and earth pressure and, more specifically, to an adapter having an assembling process which departs from the existing process, which is complicated, when laying an underground structure such as a PC power cable tunnel and an underground power distribution manhole. The present invention comprises: a block body that is assembled to be fitted using a fitting method so that it can resist high hydraulic pressure and differential settlement; a junction plate having an inclined part which is formed on one side of the block body, and which is inserted and fixed to a fixing protrusion of the block body that is formed on the other side; and an inclined water stop that is formed on the surface of the fixing protrusion, wherein the structure is changed to a watertight structure by the fitting pressure generated when the inclined part of the junction plate is tightly assembled, enabling the water stop and the junction plate to be connected and assembled to each other. |
