Sound barrier upright post and preparation method of sound barrier upright post
The invention discloses a sound barrier upright post, comprising an upright post body and sound absorption materials; the upright post body is made of reactive powder concrete; the sound absorption materials are composited on wing edges, facing one side of a sound source, of the upright post; the cross section of the upright post body is of an H shape; the reactive powder concrete comprises the components of cement, mineral powder, rice hull ash, natural sand, quartz powder, polycarboxylate superplasticizer, steel fiber and water at the mass ratio of 1: (0.15-0.25): (0.23-0.28): (1.15-1.25): (0.35-0.40): (0.02-0.025): (2.5-3.0): (0.22-0.25). The sound barrier upright post is made of the non-metal materials, so the phenomena such as corrosion, aging and bolt looseness are avoided; the service life of the upright post is equal to or even longer than a main body structure, no maintenance is needed when the upright post is used and the long-term economic benefit is obvious; the upright post has extremely high safety and reliability.
