1 概况击实试验仪器用于水利工程的土坝及公路、机场、跑道以及建筑地基等填土工程。它以标准击实方法,在一定的击实功能下测定土的含水量与干容重之关系,从而能够确定该土的最佳含水量与相应的最大干容重。目前国内生产击实仪厂家有:北京路达仪器厂、湖南湘潭液压元件厂、南京土壤仪器厂等。路达仪器厂:总击数数字显示(0～99),周期击数不可调(6击),分度为60°,采用目前普遍
1 Overview Compaction test equipment Earth dam for water conservancy projects and filling roads for roads, airports, runways and construction foundations. It complies with standard compaction method to determine the relationship between soil water content and dry bulk density under a certain compaction function so as to determine the optimum soil moisture content and the corresponding maximum dry bulk density. At present, the domestic production compaction instrument manufacturers are: Beijing Road, Instrument Factory, Hunan Xiangtan Hydraulic Components Factory, Nanjing Soil Instrument Factory. Lu Da Instrument Factory: The total number of hits digital display (0 ~ 99), the cycle is not adjustable number of hits (6 hits), sub-degree of 60 °, using the current universal
