The invention discloses a road bridge sound reduction device for municipal bridge engineering. The road bridge sound reduction device structurally comprises a rain-shedding sound insulation board, high-strength explosion-proof transparent glass, a sound insulation board fixing frame, a middle sound insulation board, a bottom sound insulation board, a fixing frame supporting foot, a fixing bolt mounting hole and a glass protection frame. According to the road bridge sound reduction device, by installing parts such as a detachable controller, sound insulation cotton in the sound reduction devicecan be replaced separately when the road bridge sound reduction device for the municipal bridge engineering is used, when the sound insulation cotton fails, the maintenance cost of the sound reduction device is low, and the practicability of the device is improved.
Description
technical field [0001] The invention relates to a sound reducing device for road bridges used in municipal bridge engineering, and belongs to the field of sound reducing devices. Background technique [0002] With the rapid development of the automobile industry and the improvement of people's living standards, on the one hand, the mileage of roads continues to increase, and the road grades continue to improve. Interfering with people's daily life, the main pollution source of environmental noise in urban areas is traffic noise. At present, the average noise in the central area of my country's cities is above 80 decibels, and it is on the rise. Among them, the impact of car noise is the most serious. According to national statistics, the national reflection of noise Pollution letters and visits account for an increasing proportion of environmental pollution complaints year by year, and have always ranked first among all kinds of environmental pollution complaints. Among envi...
