PROBLEM TO BE SOLVED: To easily prevent flexural deformation of a blocking plate. SOLUTION: A temporary restoration structure of an excavated hole temporarily restores the upper part of the excavated hole in a passable manner by installing earth retaining members 3 in the excavated hole 2 formed in a road surface 1, and supporting the blocking plate 4 for blocking the opening of the excavated hole by side parts of the excavated hole. A beam member 6 for supporting load applied to the blocking plate on the lower face side of the blocking plate is installed in a posture to cross the opening by placing both ends on both mutually facing side parts of the excavated hole.
