Supporting structure for preventing collapse of groove support

The utility model provides an anti-collapse supporting structure for a groove support, which belongs to the technical field of roadbed groove protection and comprises two protection plates, at least one U-shaped plate is fixedly arranged on opposite sides of the two protection plates, the U-shaped plates extend along the vertical direction, and openings are arranged on opposite sides of the two U-shaped plates. A vertically-through sliding groove is formed in each U-shaped plate, a telescopic rod piece is arranged between the two U-shaped plates which are opposite in the left-right direction, and the ends of the telescopic rod pieces are movably inserted into the sliding grooves. A fixing mechanism is arranged on the U-shaped plate; the two protection plates abut against the inner sides of the grooves correspondingly, the supporting piles are buried in the ground, and therefore the protection plates are fixed to the ground, the telescopic rod pieces abut against the positions between the two protection plates
