Highway crash barriers are a type of highway traffic safety facility, generally set up on both sides of the road to reduce damage to motor vehicles in accidental collisions.
[0003] According to the announcement number CN216712853U, a highway anti-collision sound insulation wall for highway traffic safety facilities engineering is disclosed, including a base and an anti-collision wall body, the base is arranged horizontally and fixed horizontally on the ground, the front parts of both sides of the top surface of the base are provided with matching grooves in the longitudinal direction, the rear parts of both sides of the top surface of the base are provided with vertical plates in the horizontal direction, the vertical plates are provided with multiple guide holes in the longitudinal direction, and the guide holes are provided with buffer components coaxially in the longitudinal direction. The beneficial effect is that the utility model fixes the base to the ground by installing bolts through the through holes, and then accurately positions and limits the anti-collision wall body to the top surface of the base by slidingly matching the matching seat and the matching groove, and then the anti-collision wall body can be arranged by installing a limit nut, and the arrangement method is simple and easy to operate.

[0025] Example:
[0026] See also Figure 1 and Figure 2A collision-proof and sound-proof wall for traffic safety comprises a wall 1, a supporting structure 2 is arranged on one side of the wall 1, a buffer device 3 is arranged on the other side of the wall 1, the buffer device 3 comprises a connecting frame 301 fixedly connected to the wall 1, and a plurality of connecting frames 301 are symmetrically arranged, a bearing 302 is fixedly embedded at one end of the connecting frame 301 away from the wall 1, a buffer water bucket 303 is arranged between each group of connecting frames 301, connecting shafts 304 are fixedly connected at both ends of the buffer water bucket 303, the connecting shafts 304 are respectively inserted into the corresponding bearings 302, and a water injection pipe 305 is fixedly connected to one side of the buffer water bucket 303.
[0027] Specifically, in order to avoid the drawback that the traditional anti-collision sound insulation wall cannot guide the vehicle, the wall 1 is fixedly installed on the ground through the support structure 2, and the buffer bucket 303 in the buffer device 3 is filled with water through the water injection pipe 305, so that when the vehicle directly hits the wall 1, the impact force of the vehicle can be slowed down and absorbed, and each buffer bucket 303 rotates with the bearing 302 through the connecting shaft 304. If the vehicle tilts and drives towards the wall 1, the rotatable buffer bucket 303 can guide the vehicle, provide a forward buffering force for the vehicle, correct the vehicle's driving trajectory, prevent the vehicle from directly rushing out of the wall 1, and reduce casualties and property losses caused by traffic accidents.
[0028] In addition, the buffer water bucket 303 can be made of plastic material, which has a simple structure and low cost.
[0029] See also Figure 1 and Figure 3 The supporting structure 2 includes a bottom plate 201 fixedly connected to the wall 1 , and fixing holes 202 are symmetrically opened on the bottom plate 201 . A reinforcing plate 203 is fixedly connected between the wall 1 and the bottom plate 201 .
[0030] Specifically, the bottom plate 201 and the wall 1 are integrally formed and arranged close to the ground. The wall 1 can be fixed to the ground by using fixing bolts passing through the fixing holes 202 , wherein the reinforcement plate 203 can increase the connection strength between the wall 1 and the bottom plate 201 .
[0031] See also Figure 1 and Figure 4 A plurality of sound-absorbing holes 6 are provided on one side of the wall 1 close to the buffer device 3 , and reflective strips 7 are fixedly connected between the sound-absorbing holes 6 . A sound-absorbing cotton 8 is fixedly connected inside the wall 1 , and the sound-absorbing cotton 8 fits closely with the plurality of sound-absorbing holes 6 .
[0032] Specifically, when a vehicle is driving on the road at night, the reflective strip 7 can reflect the light of the headlights to alert the driver, and the noise on the road can be introduced into the sound-absorbing cotton 8 through the sound-absorbing holes 6. The sound-absorbing cotton 8 can absorb the noise, so that the whole structure has a good sound insulation effect.

[0037] Working principle:
[0038] When in use, the buffer device 3 is placed facing the road, and the wall 1 can be fixed to the ground by passing the fixing bolt through the fixing hole 202. The noise on the road can be introduced into the sound-absorbing cotton 8 through the sound-absorbing hole 6, and the sound-absorbing cotton 8 can absorb the noise, so that the whole structure has a good sound insulation effect. The buffer water bucket 303 is filled with water through the water filling pipe 305, so when the vehicle directly hits the wall 1, the impact force of the vehicle can be slowed down and absorbed, and each buffer water bucket 303 rotates with the bearing 302 through the connecting shaft 304. If the vehicle tilts towards the wall 1, the rotatable buffer water bucket 303 can guide the vehicle, provide forward buffering force for the vehicle, correct the driving trajectory of the vehicle, prevent the vehicle from directly rushing out of the wall 1, and reduce casualties and property losses caused by traffic accidents.
