Problems solved by technology

[0004] (1) The fixing frame of the existing viaduct sound insulation device is fixed, so that it cannot be closely attached to the side plate of the viaduct. In bad weather, the sound insulation board is easy to shake, reducing the sound insulation effect, and there is a certain personal danger.
[0005] (2) At present, the existing elevated street lamps are fixed, which reduces the available space on the road, resulting in a decrease in traffic flow

Abstract

The invention belongs to the field of road construction and discloses a novel multifunctional viaduct sound insulation device and method. A sound insulation board is arranged; a fixing frame is weldedto the portion, below the back side of the sound insulation board, of the front side of the sound insulation plate, and tightening bolts are in threaded connection with the fixing frame; the fixing frame is provided with a first retractable rod and a second retractable rod, an outer barrel of each retractable rod is provided with through holes, the inner rod of each retractable rod is provided with a groove, and a spring is welded to each groove; the springs are welded to protrusive blocks, and the protrusive blocks are inserted into the through holes. The front side of the sound insulation board is provided with sound absorption holes, and the portion between the front side of the sound insulation board and the back side of the sound insulation board is filled with a glass sponge. According to the device and the method, by arranging the first retractable rod and the second retractable rod, the fitting degree with side plates of a bridge can be improved, the fixation firmness of the sound insulation board is enhanced, and the situation is avoided that since a traditional viaduct sound insulation device is fixed, there is a gap between the traditional viaduct sound insulation device and a viaduct, correspondingly a sound insulation board shakes under severe weather, the sound insulation effect declines, and meanwhile, a certain danger exists.

Description

Technical field [0001] The invention belongs to the field of road construction, and particularly relates to a multifunctional viaduct sound insulation device and method. Background technique [0002] Sound is a wave-like energy that needs a medium to propagate. When sound propagates in the same medium, the greater the density of the medium, the faster the propagation speed. For example, the propagation speed in the air at room temperature is about 340 m / s, and the propagation speed in the railroad track is about 5200 m / s. Another kind of sound transmission is to spread across media. That is, from one medium, through the critical contact surface of the two mediums, and enter another medium. At this time, the transmission of sound energy is essentially the transmission of vibration amplitude. When traveling across media, the greater the difference in density between the two media, the greater the loss of sound energy. In practical applications, air is the space for human activi...
