Orthogonal reinforced concrete abatis and preparation method thereof

The invention relates to an orthogonal reinforced concrete abatis and a preparation method thereof. The orthogonal reinforced concrete abatis is formed by connecting three reinforced concrete rod pieces of the same length perpendicularly and orthogonally and refers to a structural unit with a certain space. The orthogonal reinforced concrete abatis is characterized in that the three reinforced concrete rod pieces are perpendicularly and orthogonally connected in the following way that the three reinforced concrete rod pieces are perpendicularly fixed with one another by metal connectors at thepositions nearby the length midpoint of each reinforced concrete rod piece. The orthogonal reinforced concrete abatis is simple in structure, and raw material cost can be reduced. The orthogonal reinforced concrete abatis consists of square reinforced concrete rods of the certain specifications and thus can be processed conveniently at the place where raw materials are abundant, and manufacturingand transportation cost i
