Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a guard fence allowing easy assembly of two concrete blocks. SOLUTION: The guard fence comprises a bottom slab installed almost horizontally on a road installation face, and a vertical wall installed in a vertical attitude on the bottom slab. The surface of the bottom slab is provided with hollow connecting posts protruding in a predetermined position to install the vertical wall. Filling cavities for a solidifying material are opened to the lower face of the vertical wall. The filling cavity comprises a top and a surrounding wall, and its bottom part is formed as an open cavity. A filling passage for injecting the solidifying material from the outside is opened to the wall, and an insertion member is protrusively provided downward from the top inside the filling cavity. The insertion member is sized and located to be insertable in a vertical hole in a connecting post of the bottom slab when the vertical wall is installed on the bottom slab.
