Abstract

The invention discloses a road bridge noise reduction device for municipal bridge engineering. The device comprises a first silencing plate, a second silencing plate, a sound insulation plate and a water pump, wherein the first silencing plate is fixedly connected with the sound insulation plate; the side walls of the first silencing plate, the sound insulation plate and the second silencing plate are fixedly connected with a plurality of frames; the end, away from the first silencing plate, of the sound insulation plate is fixedly connected with the second silencing plate; and the side wall, close to the first silencing plate, the second silencing plate and the sound insulation plate, of each frame is provided with a groove. The device has the advantages that a driving roller is driven to rotate through water flowing in a water tank, so multiple cleaning devices move along the first silencing plate and the like, dust on the silencing plates is cleaned; the cleaning devices can move along the first silencing plate and the like, so dust cleaning effect is more comprehensive and better; and the noise reduction device on the whole bridge can be cleaned only through one or more water pumps, so economic cost is lower.

Description

technical field [0001] The invention relates to the technical field of bridge noise reduction, in particular to a road bridge noise reduction device used in municipal bridge engineering. 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. Am...
