我们在求土壤最佳含水量和最大干容重的击实试验中,普遍感到人工击实不但劳动强度大、工效低,而且所得数据往往较为分散,加之其他人为因素而影响成果的准确性。现在虽有正式生产的电击实仪,但有许多单位还未配置,而在当前水泥试验方法由硬练法改为软练法以后,许多单位的水泥胶砂成型机即将闲置,在这种情况下能否将水泥胶砂成型机改用为土壤击
In compaction tests for finding the best soil moisture content and the maximum dry bulk density, it is generally felt that artificial compaction is not only labor-intensive and inefficient, but also the data obtained are often scattered. In addition, other human factors affect the accuracy of the results. There are many units that have not yet been equipped with the electric shock test, but many cement mortar molding machines are about to be idle after the current cement test method has been changed from a hard-working method to a soft-leveling method. Under the cement mortar molding machine can be converted to soil hit
