Load reducing type sound barrier unit plate
The invention relates to a load reducing type sound barrier unit plate. The load reducing type sound barrier unit plate comprises a unit plate body (2) and lap joint parts (1), wherein the lap joint parts (1) are arranged at the two ends of the unit plate body (2) respectively and used for the mutual lap joint of the upper and lower adjacent load reducing type sound barrier unit plates. Because a gap exists between the upper and lower lap joint load reducing type sound barrier unit plates, and airflow on the road surface can penetrate a sound barrier to enter into the exterior of the road surface and play a role in pressure relieving on the road surface; the load reducing type sound barrier unit plate is provided with sound transmission holes and through holes, a part of sound waves and the airflow which enter into the interior of the unit plate is obstructed, weakened and absorbed by sound absorption lining parts, and the other part of the sound waves and the airflow which enter into the interior of the unit plate penetrates the sound transmission holes and the through holes and are discharged to the other side of the sound barrier. The load reducing type sound barrier unit plate has the advantages of not only effectively reducing noise, but also reducing airflow pressure on the road surface, reducing the pressure difference between the two sides of the sound barrier, effectively reducing the affect of the airflow on vehicles on the road surface, reducing the damage to the sound barrier, and prolonging the service life of the sound barrier.
