The causes of low-frequency noise in high-rise building pipelines are studied. Sources of increased vibration of pipeline systems are identified. The analysis of methods of damping increased vibrations of pipelines is conducted. A description of the pipeline support structures used in the field of building construction and special anti-vibration supports is given. The advantages and disadvantages of the designs of anti-vibration supports of pipeline systems are identified. A method for improving the existing anti-vibration support consisting of all-metal elastic-damping elements pressed from spirals of wire is proposed. An anti-vibration support, consisting of a body and sealed capsules filled with a damping fluid, was developed. The design of the anti-vibration support, which allows adapting to the vibration mode due to the displacement of the pipeline relative to the support body and the redistribution of the damping fluid pressure in the capsules, is presented. The effectiveness of the proposed design support was confirmed experimentally.
