[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1 and Figure 2As shown, the utility model proposes a sound reduction device for road and bridge engineering, including a bridge deck 1, a guard wall 101 is fixedly provided on the side of the bridge deck 1, a guardrail 102 is fixedly provided on the guard wall 101, and also includes a mounting plate 2 and a limiting fixing mechanism 3, the mounting plate 2 and the bridge deck 1 are movably connected, the limiting fixing mechanism 3 is fixedly connected to the front side of the bridge deck 1, the limiting fixing mechanism 3 includes a fixing buckle 301, a bolt 302 and a limiting plate 307, the limiting plate 307 is slidably connected to the lower front side of the bridge deck 1, the limiting plate 307 is set to an L-shaped structure, the limiting plate 307 is slidably connected to the upper part of the guard wall 101, the fixing buckle 301 is fixedly connected to the lower front side of the bridge deck 1, the fixing buckle 301 is slidably connected to the guardrail 102, the middle part of the bolt 302 is slidably connected to the fixing buckle 301 and penetrates the fixing buckle 301, and one end of the bolt 302 is threadedly connected to the front side of the mounting plate 2.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the left and right sides of the lower part of the bridge deck 1 are both provided with slide grooves 306 , and the slide grooves 306 are set as T-shaped groove structures. The limit plate 307 is slidably connected to the slide grooves 306 to limit the sliding position of the limit plate 307 . The upper part of the mounting plate 2 is set as a bent structure to prevent rainwater from directly eroding the limit fixing mechanism 3 and causing the limit fixing mechanism 3 to rust, thereby increasing the service life of the device. The front side and the upper part of the mounting plate 2 are fixedly provided with a transparent sound insulation plate 4, which has a sound insulation effect while ensuring light transmission. The front side of the limiting plate 307 is provided with a guard plate 303, and a spring 305 and a damping 304 are provided between the guard plate 303 and the limiting plate 307, which have an anti-collision and shock-absorbing effect on the guard plate 303, thereby reducing the damage to the mounting plate 2 caused by vehicle collisions.

The connecting groove 202 and the connecting block 201 are in a chime-connected connection, which increases the connection tightness between adjacent mounting plates 2 and improves the sound insulation effect.

[0021] When in use, unscrew the bolt 302 from the fixing buckle 301, align the lower opening of the fixing buckle 301 with the guardrail 102, and at the same time slide the limit plate 307 upward along the slide groove 306, and move the mounting plate 2 and the bottom of the fixing buckle 301 to complete the buckling of the guardrail 102. Under the action of gravity, the limit plate 307 falls along the slide groove 306 to complete the buckling of the guardrail 101, and the rotating bolt 302 passes through the fixing buckle 301 to connect the mounting plate 2, completing the fixation of the guardrail 102 by the fixing buckle 301, and at the same time connects with the adjacent mounting plate 2 through the connecting groove 202 and the connecting block 201. Multi-point limitation can ensure the stability of the installation of the mounting plate 2, and can quickly complete the splicing and installation of the mounting plate 2. The installation is convenient, the construction period is short, and it is convenient for large-scale installation operations.
