To improve efficiency and veracity of soil sampling in testing bulk density, the cutting ring method and in situ soil tube method were combined and a multi-segment in situ soil sampler was designed.
为了提高土壤容重测定中土样采集的效率和精准性，将环刀法和原状取土管法结合，进行了分段式原状取土器的研制。
The results of sampling taken from in-situ of the model test show that constructing model by this design method is available; and the density and property of the model material are uniform and stable.
原位取样测试结果表明，按照这种方法设计制作的模型，最终能达到模型中同一类型材料所要求的密度整体相对一致的效果，从而提高了物理模型中材料力学性质的稳定性。
The invention relates to an in situ deposit-aqueous interface water-quality sampler and a sampling method thereof.
