Problems solved by technology

[0004] The embodiment of the present application provides a light-weight high-strength sound barrier cement board for highways, which solves the problem of sound waves being easily diffracted, transmitted, and reflected to the outside of the sound barrier due to the poor sound absorption and noise reduction effect of the sound barrier in the prior art. A technical problem with a greater impact, the effective energy consumption of the sound wave is reduced to reduce the sound, and at the same time absorb the sound, which can greatly reduce the sound wave energy transmitted to the sound barrier, effectively improving the sound absorption and noise reduction effect

Abstract

The invention discloses a lightweight high-strength sound barrier cement board for highways, which belongs to the technical field of highway sound barriers. The lightweight high-strength sound barrier cement board for highways includes: a front mounting board; A sound-absorbing cavity is formed between them; light-weight high-strength cement boards are arranged in the sound-absorbing cavity; multiple sound-absorbing shells are arranged on the front mounting plate to form an array of sound-absorbing shells, and each sound-absorbing shell has a sound-absorbing shell The cavity and the sound attenuation inlet connected with the sound attenuation cavity, and the sound attenuation inlet of each sound attenuation shell is away from the front mounting plate, and the sound attenuation and dissipation space is formed between the outer surfaces of the multiple sound attenuation shells and the front mounting plate. The light-weight high-strength sound barrier cement board for expressway disclosed by the present invention realizes the effective energy consumption and weakening of sound waves to reduce sound, and at the same time absorbs sound, so that the sound wave energy transmitted to the sound barrier can be greatly reduced, effectively improving the sound absorption and sound reduction effect .

Description

technical field [0001] The invention relates to the technical field of expressway sound barriers, in particular to a lightweight high-strength sound barrier cement board for expressways. Background technique [0002] The sound barrier is a wall structure installed beside the railway and road to reduce the impact of driving noise on nearby residents. The sound barrier is mainly used for sound insulation and noise reduction of roads, expressways, elevated composite roads and other noise sources. It is divided into reflective sound barriers for pure sound insulation, and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. The sound barrier is between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby reducing the impact of noise in a certain area where the receiver is located. [0003] In the prior art, the boards made of sound-...
