Environment-friendly noise reduction device for viaduct

Abstract

The invention discloses an environment-friendly noise reduction device for a viaduct. The first layer of the noise reduction device is a fluffy perlite, the second layer is a microporous layer for enhancing sound permeability, the third layer is a sound absorbing layer, which can be filled with a sound absorbing material for improving the noise reduction effect, so that the noise is fully absorbedby the sound absorbing material, the fourth layer is a vibration transmitting layer for eliminating resonance and effectively reducing the propagation of noise and comprises a waste textile fiber board, the fifth layer is a sound insulation layer, which can be filled with a sound insulation material for further improving the noise reduction effect, the sixth layer is a cement solid surface, and abottom layer is provided with a reinforcing steel mesh board for improving the overall strength and durability of the noise reduction device. The noise reduction device is a one-step molded body. Thenoise reduction device has both sound absorbing and sound insulation functions and can eliminate resonance, and has the characteristics of good noise reduction effect, low cost and environment friendliness.

Description

technical field [0001] The invention relates to the technical field of noise reduction materials and acoustic environment engineering, in particular to an environment-friendly noise reduction device for viaducts. Background technique [0002] With the deepening of urbanization in my country, many highways and viaducts in urban construction are built next to residential buildings. The noise of construction and traffic vehicles seriously interferes with the normal life of residents. Construction noise and traffic noise will cause human body damage. Harm, causing irritability, insomnia, neurasthenia, short temper and other problems, seriously affecting people's work and study, therefore, it is particularly important to control and eliminate noise pollution to the environment and the harassment of people's lives and work. [0003] In order to reduce the interference of traffic noise and construction noise to residents, some plates are installed on both sides of the viaduct and ar...
