The invention belongs to the technical field of mining engineering gob-side entry retaining support, and discloses a yielding strong resistance and automatic gangue blocking type roadside reinforced concrete column structure and a construction method. The structure comprises a pressure dispersion system used for completing yielding; the waste rock prevention system is used for automatically ejecting a metal net to form a waste rock blocking wall; the power system is used for enabling the yielding shrinkage rod to rise to push the yielding cushion block to be tightly attached to the upper top plate, so that the upper top plate weighting sensor is in tight contact with the rock; the solidification monitoring system is used for monitoring the solidification state of reinforced concrete in the mold through a moisture monitor; the real-time monitoring system is used for monitoring dynamic change values of the top plate pressure sensor and the air bag pressure monitor on the upper portion through a real-time monito
