Compaction springback device and compaction degree measuring method
The invention relates to a compaction springback device and a compaction degree measuring method.The compaction springback device comprises an impact head and a device support, the bottom of the impact head is provided with an impact head contact part used for being in contact fit with a road surface, and a device base comprises an annular contact part annularly arranged on the periphery of the impact head contact part and used for being in contact fit with the road surface; a spring used for exerting downward acting force on the impact head is arranged between the device base and the impact head, the impact hammer is used for impacting the upper end of the impact head downwards, and the height lifting mechanism is used for lifting the height of the impact hammer. The compaction springback device further comprises a height measuring device used for detecting the springback height after the impact hammer collides with the impact head. The invention provides a compaction degree measuring method for measuring the compaction degree of a road surface by using the rebound value of the road surface and a compaction rebound device used in the compaction degree measuring method.
本发明涉及一种击实回弹装置及压实度测量方法，击实回弹装置包括撞击头和装置支座，撞击头的底部具有用于与路面接触配合的撞击头接触部，装置底座包括环设于撞击头接触部外围的用于与路面接触配合的环形接触部，装置底座与撞击头之间设置有用于对撞击头施加朝下方向作用力的弹簧，击实回弹装置还包括用于朝下撞击所述撞击头上端的撞击锤及用于提升所述撞击锤高度的高度提升机构，击实回弹装置还包括用于检测撞击锤碰撞撞击头后回弹高度的高度测量装置。本发明提供了一种利用路面回弹量来测量路面压实度的压实度测量方法及该压实度测量方法中使用的击实回弹装置。
