Abstract | The utility model relates to the technical field of building construction, and discloses an air lift reverse circulation secondary hole cleaning structure which comprises a hole cleaning pipeline, an air compressor, a sedimentation tank and a pressure relief device, the pressure relief device comprises a seat body, and a positioning hole is formed in the seat body; one end of the hole cleaning pipeline extends to a to-be-cleaned hole position, and the other end of the hole cleaning pipeline penetrates through the positioning hole and extends into the sedimentation tank; a PVC air supply pipe is arranged in the hole cleaning pipeline, one end of the PVC air supply pipe extends to the position of a hole to be cleaned, and the other end of the PVC air supply pipe is connected with an air compressor. High compressed air generated by the air compressor is conveyed to the position of a to-be-cleaned hole and mixed with slurry in the hole, so that a slurry-air mixture with the density smaller than that of the slurry |
