Abstract
The invention discloses a glass-fibre-reinforced plastic (GFRP) noise barrier used for a controlled-access highway. The bottom parts of a GFRP noise barrier panel and a GFRP noise barrier rear panel are sealed by a plastic support part. The GFRP noise barrier panel, the GFRP noise barrier rear panel and the plastic support part form a cavity. The cavity is provided with a galvanized sheet at the side near the GFRP noise barrier rear panel, and is also filled with sound absorbing glass fiber cotton and hydrophobic glass fiber fabrics. The GFRP noise barrier panel is provided with sound absorbing holes, and the apertures of the sound absorbing holes are gradually decreased from the outer part to the inner part. The GFRP noise barrier panel comprises a first plane and a second plane which are located in different planes. The GFRP noise barrier used for the controlled-access highway provided by the invention has the advantages of easy assembly, obvious effect on sound absorption and sound insulation, good corrosion resistance and long service life for more than 25 years.
