Road construction noise damping device

The utility model is applicable to the technical field of devices for road construction, and provides a noise damping device for road construction, which comprises a construction fence, I-shaped fixing rods and a damping device, a buffer plate is arranged in the construction fence, and first sliding rods are slidably connected to the four corners of the buffer plate correspondingly. According to the road construction noise damping device, the buffer plate, the first sliding rod, the first spring and the honeycomb plate are arranged, the function of damping and reducing noise in construction is achieved, due to the fact that sound is sound waves generated by object vibration, the vibration can be buffered through the elastic force of the first spring, and the noise reduction effect is good. According to the invention, the purpose of noise reduction is achieved, and the problems that a common sandwich board guardrail is poor in sound insulation effect, the sandwich board guardrail generally absorbs sound throug
