目前普遍采用的碾压混凝土压实质量控制方法是密度法。碾压后，挖坑取样或采用核子密度水分计选点测量碾压混凝土的湿密度。这种方法占用大量施工时间，并存在选测点的随意性。由笔者研制成功的压实计，安装在振动碾上，在碾压过程中可随时知道填料是否压实，实现了压实质量的实时全面控制。本文介绍压实计的工作原理、室内模块试验及现场应用试验情况。
The commonly used method of compaction quality control of roller compacted concrete is the density method. After compaction, pit sampling or measurement of the density of the RCD using a nuclear density moisture meter. This method takes up a lot of construction time, and there is a random selection point. Developed by the author of the compaction meter, mounted on the vibration grind, the rolling process can always know whether the packing compaction, to achieve the compaction quality of real-time comprehensive control. This article describes the working principle of compaction meter, indoor module test and field application test situation.
