SOLUTION: A plurality of trapezoidal blocks 1 in which bases are formed to opening sections 2, projecting sections 3 for a connection are formed at one side ends and recessed sections 4 fitted to the projecting sections 3 are formed at the other side ends are arranged in a column, and a plurality of the trapezoidal blocks 1 are connected successively by fitting the mutually adjacent projecting sections 3 and recessed sections 4, thus forming the barricade 10.
