机场场道切缝导(倒)角金刚石锯片及其施工工艺试验研究

Experimental Study on Chamfering Diamond Saw Blade for Airport Runway and the Construction Technology

为减少飞机轮与路面摩擦时的应力集中及机械除雪对航道路面的破坏,防止飞机在起飞降落过程中因飞机轮与路面伸缩缝摩擦引起的灰尘进入飞机发动机而引发事故,及延长机场航道路面的使用寿命,机场航道路面所有暴露的切缝、边缘及尖角都要进行导(倒)角处理。对大型机场场道切缝导(倒)角金刚石锯片和切割施工工艺试验进行了研究,对于国内新机场建设极具参考价值。

To reduce the stress concentration on the friction between aircraft wheel and road surface and reduce the channel pavement destruction by snow-clean vehicle,to prevent the dust produced in the friction of aircraft wheel and road joints from entering to aircraft engine and to prolong the service life of airport runway,all the exposed kerfs,edges and sharp corners in large airport field road should be chamfered.The study was made on the chamfering diamond saw blade and the chamfering construction technology,which was considerably valuable for domestic airport construction.
