Highway asphalt thickness measuring equipment adopting backfill-free coring method and measuring method of highway asphalt thickness measuring equipment
The invention relates to road asphalt thickness measuring equipment and a road asphalt thickness measuring method based on a backfill-free coring method, and belongs to the field of asphalt thickness measurement. A lifting assembly drives a rotating upper cylinder and a rotating lower cylinder to descend, and the rotating upper cylinder and the rotating lower cylinder rotate, so that coring is completed on a road asphalt layer; the rotating upper cylinder drives the rotating lower cylinder to rotate through the torque rod, and the torque rod forms different torque forces through the hydraulic oil cavity and forms detection pressure through the pressure detector. When the rotating lower cylinder moves to the boundary of the asphalt bottom, the driving force of the torque rod of the rotating lower cylinder is changed instantly, and then the pressure sensed by the pressure detector is changed, so that the bottom of the asphalt layer can be indirectly determined, and the thickness of the asphalt layer is further determined. And then the rotating lower cylinder and the rotating upper cylinder move upwards, the asphalt core body does not need to be taken away, and the asphalt core body is kept at the original position, so that asphalt is not damaged, and subsequent repair is also needed.
本发明涉及免回填式取芯法公路沥青厚度测量设备及其测量方法，属于沥青厚度测量领域，通过升降组件带动旋转上筒和旋转下筒进行下降，旋转上筒和旋转下筒进行转动，以在公路沥青层完成取芯，旋转上筒通过扭矩杆带动旋转下筒转动，扭矩杆通过液压油腔形成不同的扭矩力并且通过压力探测器形成探测压力。当旋转下筒移动至沥青底部界限的时候，则会使得旋转下筒的扭矩杆的驱动力瞬间发生变化，进而使得压力探测器感应到的压力发生变化，这样就可以间接地确定达到了沥青层底部，进而确定沥青层厚度。然后旋转下筒和旋转上筒向上移动，并且不需要带走沥青芯体，沥青芯体保留在原始位置，因此不会造成沥青破坏，也需要进行后续修补。
