摘要
核子密度水分仪测定土、石、混凝土、沥青等建筑材料原位密度和含水量具有无损、快速等优点.详细介绍了核子密度水分仪在堤防工程中的标定方法,并与环刀法相结合进行渠堤填筑压实度检测,提高了工作效率,保证了工程质量,可为相关工程提供参考.
Nuclear density moisture meter can measure the density, moisture content, compactness degree and other parameters of soil, stone, concrete, asphalt and other construction materials, and has non-destructive and fast advantages. In this paper, calibration method of nuclear density moisture meter in the dike project is detailedly introduced. Combined with core cutter method, the method is applied to test compaction degree of channel bank filling. The results show that it greatly improve work efficiency, ensure the project quality, and can provide a reference for the related projects.
