The present invention relates to a buried cutoff wall for a road capable of being drastically deployable. The objective of the present invention is to provide a buried cutoff wall for a road which blocks water introduced into a road by erecting a cutoff wall buried in the road when flooding is expected; which minimizes a gap of a rotation portion to prevent the inflow of foreign materials while less road impact transmits to vehicles passing the road in usual; and autonomously rotates without external help in a state where a space required for the rotation of the cutoff wall is secured by rotating while varying the gap in the operation. The buried cutoff wall for a road capable of being drastically deployable comprises: a receiving part buried in a road to receive and support a cutoff wall; the cutoff wall to cut water off by blocking the road when erected in the receiving part; a retractable unit mounted on the receiving part to provide retractable force to erect or receive the cutoff wall; a movable rotation part to horizontally vary a gap between the cutoff wall and the receiving part coupled to each other to rotate the cutoff wall when the retractable unit is retracted; and closing walls installed in both side ends of the receiving part to support the erected cutoff wall while being in contact with the erected cutoff wall. |
