Noise reduction device for highway construction
The invention provides a noise reduction device for highway construction, and solves the problems that as roofs of existing movable house noise reduction devices are mostly of closed structures, noise is reflected back and forth in a house and cannot be discharged, and the body health of constructors is greatly affected. The sound barrier comprises two sound barrier walls which are oppositely arranged in a left-right spaced mode, the upper ends of the sound barrier walls are bent towards the inner sides of the sound barrier walls to form arc-shaped wall plate structures, and a vertically-through sound discharging space is formed between the opposite end faces of the arc-shaped wall plate structures on the left side and the right side. A plurality of cross beam structures which are arranged at intervals front and back are detachably connected between the opposite end faces of the arc-shaped wall plate structures on the left side and the right side; a supporting bottom plate is fixedly arranged at the bottom of the sound barrier wall, an elastic supporting pad is fixedly arranged at the bottom of the supporting bottom plate, a telescopic device capable of stretching out and drawing back up and down is fixedly arranged on the outer side of the sound barrier wall, walking wheels are fixedly arranged at the lower end of the telescopic device, and when the telescopic device stretches out, the walking wheels can be pushed to the ground so as to lift the supporting pad.
本发明提供了一种公路施工用降噪装置，解决了现有的可移动式房屋类降噪装置的屋顶多为封闭结构，导致噪音在屋内来回反射、无法排出，对施工人员的身体健康影响较大的问题。本发明包括两个左右间隔且相对设置的声障墙，声障墙的上端向其内侧弯曲形成弧形墙板结构，左右两侧的弧形墙板结构的相对一端面之间形成上下通透的排声空间，左右两侧的弧形墙板结构的相对一端面之间可拆连接有多个前后间隔设置的横梁结构；声障墙的底部固定设有支撑底板，支撑底板的底部固定设有具有弹性的支撑垫，声障墙的外侧固定设有能够上下伸缩的伸缩装置，伸缩装置的下端固定设有行走轮，伸缩装置伸出时能够将行走轮推至地面上以将支撑垫抬起。
