METHOD FOR MAKING OF NOISE SCREEN Russian patent published in 2010 - IPC E01F8/00 

FIELD: construction.

SUBSTANCE: invention is intended for making of noise screens, reflecting and suppressing acoustic waves of high capacity, which are generated along with passing of high speed train sets. Method for manufacturing of noise screen, including installation of support stands in the form of double tee on foundation, and a metal plate with thickness of at least 5 mm is welded to double tee along full length of stand. Then "П"-shaped section bars are fixed by SFS self-tapping screws to plate through vibration damping gasket, joining them to form sections, noiseproof material is laid into sections, and perforated metal sheet is fixed to support stand and "П"-shaped section bars, covering space from stand to stand.

EFFECT: screen may withstand high dynamic loads, preserving high noiseproof properties at the same time.
