The concrete prefabricated base is vertically arranged along the slope direction. A reserved hole is provided above the concrete prefabricated base. The concrete column is inserted into the reserved hole one by one. A protruding structure is provided on one side of the concrete column. A groove structure is provided on the other side of the concrete column. The protruding structure of the concrete column is limitedly arranged in the groove structure of the adjacent concrete column, and the protruding structure is fixedly connected with the adjacent concrete column through the embedded steel bars. A pre-embedded steel bar is provided at the top of the concrete column. The barbed wire cage is wound on the pre-embedded steel bar.

[0006] Preferably, the groove structure is arranged along the length of the concrete column.

[0007] Further preferably, the protruding structure is arranged at intervals along the length direction of the concrete column.

[0008] Further preferably, the embedded steel bars are arranged horizontally.

[0009] Further preferably, the height of the concrete column is 2.0m-2.5m, and the depth of the reserved hole of the concrete prefabricated base is 70-100cm.

[0010] Further preferably, the concrete prefabricated base is closely embedded along the slope direction.

[0011] Further preferably, the distance between two adjacent concrete columns is 10 cm.

[0012] The assembled steep slope railway fence protection structure has the advantages of being convenient to disassemble and assemble, being applicable to different slope conditions, having low construction difficulty, and being safe and stable. BRIEF DESCRIPTION OF DRAWINGS
