1. Brief introduction of product:
Sound barrier pillar is an important part of sound barrier system of high speed train, which is mainly composed of a steel structure columns and suction Shengbing insulation board is composed of two parts, H type steel column is the main stress components of noise barrier, it through the H type steel, plate, connected by welding, weld shall bear when speed of impact millions of 380 kilometers of high-speed train, the personnel to ensure the safety of life and property, service life of fifty years, it must be strictly manufactured in a factory, welds shall be implemented in accordance with the national standard of pressure vessel detection, strict reached three grade pressure vessel inspection standard. Site installation, it is welded and fixed on the road bump wall or rail embedded steel plate by bolts or. At the same time, the sound absorption and insulation board is sound insulation and absorption of the main parts, the high strength spring clip is fixed on the H type column groove, forming a sound barrier.

2. Characteristics of product:
Sound barrier pillar design has been more fully into the elevated high-speed roads, city light rail, subway wind load, vehicle crash safety and all-weather outdoor corrosion problems. It has the advantages of beautiful appearance, exquisite production, transportation, convenient installation, low cost, long service life, the use of anti noise is particularly suitable for overhead high speed road and city light rail, subway, is the most ideal noise insulation facilities of modern city. Sound barrier height in the 1m column, 5m, sound coverage effective regional average reduction of 10 ~ 15dB (A) (125Hz ~ 40000Hz, 1 / 3 octave), up to 20dB (A). Generally speaking, the higher the sound barrier, or from the sound barrier denoise farther, the better, the sound barrier pillar design and manufacturing level of the higher requirements.
