The invention relates to the technical field of grouting equipment, and discloses a grouting device for preventing collapse of muck slope support. The grouting device comprises a pipe body, wherein a grouting channel is formed in the pipe body, and a backflow channel is formed in the middle of the inner wall of the pipe body. Through the arrangement of a pull rope, a lantern ring, an extrusion plate and a rubber ring, a bypass hole is formed in the side face of the pipe body for grouting, grouting reinforcement of the side wall of the grouting pipe body can be achieved, and therefore the risks of ground surface settlement and collapse are reduced; and meanwhile, the pull rope can drive the lantern ring to move downwards, and therefore a baffle blocks the backflow channel, the grouting pressure in the pipe body is enough, a first supporting rod can be driven to enable the extrusion plate to extrude the outer side, the rubber ring is transversely expanded, the grouting pipeline is blocked, the problems that slu
