Road pavement paving thickness measuring device with drill-in structure
The invention relates to the technical field of road pavement paving thickness measurement, in particular to a road pavement paving thickness measuring device with a drilling-in type structure. The drilling device comprises a supporting device and a drilling assembly installed at the bottom end of the supporting device, the drilling assembly comprises a starting device, an inner core is arranged at the inner end of a drill bit, a top bead is arranged at the bottom end of the inner core and matched with the bottom end of the drill bit in a sleeved mode, the inner core is sleeved with an inflation cavity, and the inflation cavity is sleeved with a clamping ring. According to the device, a starting device drives a drill bit to conduct drilling treatment on the thickness of pavement cement (not dry), the drill bit rotates and moves downwards along with the starting device, an inflation cavity is clamped and limited by a clamping ring, an inner core overcomes cement resistance and keeps static relative to the inner end of the drill bit, and when the drill bit touches the bottom, a top ball moves towards the inner end of the drill bit; the inflation cavity and the clamping ring are not fixed, the inner core moves upwards, and the pavement paving thickness can be measured by observing the position where the outer side of the drill bit is flush with the cement surface.
本发明涉及道路路面铺设厚度测量技术领域，具体地说，涉及一种带有钻入式结构的道路路面铺设厚度测量装置。其包括支撑装置以及安装在支撑装置底端的钻孔组件，钻孔组件包括启动装置，钻头内端设置有内芯，内芯底端设置有顶珠，顶珠与钻头底端套接配合，内芯外侧套接有充气腔体，充气腔体外侧套接有夹环。本发明中，启动装置带动钻头对路面铺设水泥（未干）厚度进行钻孔处理，钻头随着启动装置旋转下移，充气腔体由于受到夹环夹持限定，内芯克服水泥阻力与钻头内端保持相对静止，当钻头触底后，顶珠向钻头内端移动，充气腔体与夹环失去固定，内芯向上移动，观察钻头外侧与水泥表面平齐位置，即可测出路面铺设厚度。
