Abstract

The invention discloses a light high-strength sound barrier cement board for an expressway, and belongs to the technical field of expressway sound barriers. The light high-strength sound barrier cement board for the expressway comprises a front face mounting plate, a back face mounting plate, a light high-strength cement board and a plurality of silencing shells; a sound absorption cavity is formed between the back face mounting plate and the front face mounting plate; the light high-strength cement board is arranged in the sound absorption cavity; the plurality of silencing shells are arranged on the front face mounting plate to form a silencing shell array, each silencing shell is provided with a silencing cavity and a silencing inlet communicated with the silencing cavity, and the silencing inlet of each silencing shell deviates from the front face mounting plate; and a silencing dissipation space is formed between the outer surfaces of the plurality of silencing shells and the front face mounting plate. According to the light high-strength sound barrier cement board for the expressway, effective energy consumption reduction and sound attenuation are conducted on sound waves, sound absorption is conducted at the same time, the energy of the sound waves conducted to a sound barrier can be greatly reduced, and the sound absorption and attenuation effect is effectively improved.

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-...
