Pavement structure depth detection device and detection method thereof
The invention relates to a pavement structure depth detection device and a detection method thereof, and effectively solves the problems that a sand spreading method is relatively large in error and a laser method has principle defects. Water flow carries fine sand to permeate into the pavement gaps, compared with a traditional sand scraping mode, the pavement gaps can be filled more fully, the reduction amount of the fine sand in the sand storage chamber serves as the volume of the fine sand permeating into the pavement gaps, compared with a traditional mode that the sand amount is measured in advance and scraping is carried out, manual subjective judgment on the scraping state is eliminated, and the construction efficiency is improved. Therefore, the sand amount metering mode is more reasonable, the reduced sand amount in the sand storage chamber is calculated through the change of the air pressure, tiny volume change can be accurately metered, the spreading area of the fine sand is limited to be a constant value by the barrel body, more reasonable and accurate sand amount and area can be obtained, and then a more accurate detection result is obtained.
本发明涉及一种路面构造深度检测装置及其检测方法，有效的解决了摊沙法误差较大，激光法存在原理性缺陷的问题；通过水流携带细沙渗入路面缝隙中，相对于传统的刮沙方式，能够更充分的填充路面缝隙，以储沙室内细沙的减少量作为渗入路面缝隙中的细沙体积，相比与传统的事先量取沙量并通过刮平的方式，消除了对刮平状态的人为主观判断，故本发明的沙量计量方式更为合理，再通过气压的变化计算储沙室内减少的沙量，能够准确计量微小的体积变化，加上筒体将细沙的摊布面积限定为恒值，本发明能够得到更为合理准确的沙量和面积，进而得到更为准确的检测结果。
