River channel water pipe buttress and preparation method thereof

The invention relates to the technical field of riverway water pipe buttresses, and discloses a riverway water pipe buttress. Comprising a drainage pipe support, a U-shaped pipe hoop is in threaded connection with the upper surface of the drainage pipe support, a drainage pipe is sleeved with the U-shaped pipe hoop, I-shaped steel is clamped to the lower surface of the drainage pipe support, a U-shaped bolt is in threaded connection with the lower surface of the I-shaped steel, and a galvanized steel pipe column is arranged on the lower surface of the U-shaped bolt; according to the anti-skid device, an anti-skid seat moves downwards, so that the anti-skid seat can be embedded into the top end of a U-shaped bolt, a sliding rod is pushed to push an extrusion bag to move, the extrusion bag can be attached to the top end of the U-shaped bolt for wrapping, and through movement of the sliding rod, a limiting rod can be embedded into the anti-skid seat to fix the sliding rod; the movable rod is pushed to enable the
