Sound-isolating screen for urban roads and bridges

Abstract

The invention discloses a sound-isolating screen for urban roads and bridges. The sound-isolating screen comprises a sound-isolating screen main body, wherein the sound-isolating screen main body is composed of a dustproof plate arranged at the top of the sound-isolating screen main body and a sound-isolating plate arranged at the bottom of the dustproof plate; and the dustproof plate is welded with the sound-isolating plate. According to the sound-isolating screen, a damping plate is arranged on the sound-isolating screen for urban roads and bridges; the physical isolation is achieved while the noise spread is stopped; the soundproof effect is excellent and the noise pollution is effectively reduced; the raw materials are capable of effectively retarding flame and preventing the fire spread, so that the safety is higher; the raw materials are also effective anticorrosion, so that the service life of the sound-isolating screen is prolonged; a transparent plate is arranged, the light transmittance is promoted in a visual road section and the lighting effect is excellent, so that the traffic accident caused by unclear sight of the driver can be avoided; and a spring bumper is arranged, so that the collision of the vehicle to the sound-isolating screen can be effectively relieved, the sound-isolating screen can be prevented from being damaged and the safety of the sound-isolating screen and the driver can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of sound insulation screens, in particular to a sound insulation screen for urban road bridges. Background technique [0002] There are three main types of noise pollution in urban traffic, namely noise from urban roads, urban rail transit and urban highways. With the rapid development of urban traffic, the impact of road traffic noise is increasing day by day. In order to reduce noise pollution, more and more different types of noise barriers are appearing around us. Among them, the acoustic and aesthetic standards of urban bridge noise barriers have been greatly developed and improved. For its type, structural form, material, etc. A lot of research has been done at home and abroad. With the development of science and technology, there are more and more sound insulation screens, and their functions are becoming more and more powerful. Among them, there are more sound insulation screens for urban roads and b...

Problems solved by technology

[0003] However, most of the existing sound insulation screens only use physical partitions for noise reduction. The noise reduction effect is not good. At the same time, the lighting is not good, resulting in a darker line of sight in the visible road section, and cannot effectively reduce vibration and prevent related collisions.
