Disclosed is a bifoil enhanced prestressed steel column for the anti-rockfall support wire cable net, wherein the channels which are in the two sides of the flange beam are immovably provided with two channel steels with circular arch shape. A plurality of rib reinforcement blocks are fixed at the two ends and middle of the channel steel, wherein the oblique reinforcement plate is fixed from the two sides of the channel steels to the two sides of the flange beam and the cleat rib reinforcement is fixed at the two sides of the rotating connecting cleat. The utility model doubles in the capability of positive direction bending resistance compared with the prior steel column and is 12 times in the capability of side direction bending resistance, improving the protection capability of the flexible security system greatly.
