Safe noise reduction road barrier
The invention discloses a safe noise reduction road barrier. The road barrier comprises a barrier body, the barrier body comprises a recycled rubber base body made of recycled rubber, a plurality of noise reduction holes are formed in the recycled rubber base body, a silk screen layer is arranged outside the recycled rubber base body, a secondary protection layer is arranged outside the silk screen layer, and a sandstone layer is arranged outside the secondary protection layer. The base body of the safe noise reduction road barrier is made of recycled rubber which has a good energy absorption effect when a vehicle collides, no metal component flies out, the safe noise-reducing road barrier has a good protection effect on the vehicle and a driver, sound absorption coefficients of more frequencies can be increased through the combination of the sandstone layer and the plurality of noise reduction holes, and after a plurality of safe noise reduction road barriers form an isolation belt, the sound absorption and noise reduction effects are obvious. The sandstone layer has the effects of fire prevention and noise reduction, fire catching of the recycled rubber base body can be avoided, aging of the recycled rubber base body is delayed, then the service life of the safe noise reduction road barrier is prolonged, the price of recycled rubber is low, and the manufacturing cost is low.
本发明公开了一种安全降噪隔离墩，包括墩体，墩体包括由回收橡胶制成的回收橡胶基体，回收橡胶基体上开设有多个消音孔，回收橡胶基体外设置有丝网层，丝网层外设置有二次防护层,二次防护层外设置有砂岩层。本发明的安全降噪隔离墩采用回收橡胶制成基体，车辆碰撞有很好的吸能作用，没有金属构件飞出，对车辆和驾驶人员有很好的保护作用，并且砂岩层和多个消声孔组合可以增加更多个频率的吸声系数，多个安全降噪隔离墩形成隔离带后，吸声降噪效果明显。砂岩层具有防火降噪的作用，能避免回收橡胶基体着火，延缓回收橡胶基体老化，进而延长安全降噪隔离墩的使用寿命，回收橡胶的价格比较低，制造成本低。
