The invention discloses a high-pressure pipeline which comprises a pipeline body, wherein the pipeline body is arranged inside a pipe trench; the outer circumference of the pipeline body is sleeved by an outer casing pipe; the part between the outer casing pipe and the pipeline body is filled with hard wooden supports; the outer casing pipe is fixed on a pipeline bracket through a pipe hoop; the pipe trench is further filled with fine sand; the pipeline bracket comprises a horizontal part for placing the outer casing pipe; a vertical part for supporting the horizontal part is arranged below the horizontal part. By adopting the high-pressure pipeline, conduction of vibration can be effectively prevented, and thus severe and extraordinarily serious safety accident can be avoided. In addition, the high-pressure pipeline is convenient to repair and maintain.
