根据在流态淤土中取样容易脱落和被扰动的特点,我们采用了在钻孔内封闭取样器的方法,并根据淤土的流动程度和试验要求,革新了两种不同形式的取样器。通过生产实践表明,这几种革新的取样器适
Based on the characteristics of samples that are easily shed and disturbed in the flow silt, we have adopted a method of closing the sampler in the borehole and have adapted two different types of samplers based on the flow of silt and the test requirements. Through the production practice shows that these innovative sampler suitable
