The invention discloses an on-site sampling operation device and method for a large-diameter sediment sampler, the on-site sampling operation device comprises a hoisting structure, an anti-falling structure, an ejection structure and a pipe planing structure, a sampling pipe is hoisted through the hoisting structure, the anti-falling structure is mounted at a sampling pipe interface, a sample in the sampling pipe is segmented, and the sample in the sampling pipe is prevented from falling off during hoisting; a sample in the sampling pipe is ejected through the ejection structure, so that the sampling efficiency is improved; and the sample tube is segmented and split through the tube planing structure, so that subsequent analysis of the sample is facilitated. By means of the operation process method, the problems of lifting, falling prevention, ejection and sample separation in the sampling process of the large-caliber vertically-collected sediment can be well solved, the sample quality is guaranteed, sample carrying is convenient, subsequent sample analysis is convenient, the sampling efficiency is greatly improved, and the integrity and fidelity of the sample are guaranteed.
本发明公开了大口径沉积物取样器现场取样作业装置及作业方法,包括吊装结构、防脱结构、顶出结构、刨管结构,通过吊装结构对取样管进行起吊,在取样管接口处安装防脱结构,将取样管内样品分段同时避免取样管内样品吊装时脱落,再通过顶出结构顶出取样管内样品,提高取样效率;通过刨管结构将样品管分段后剖开,方便样品后续分析。通过以上作业流程方法可以很好的解决大口径立式收放的沉积物取样过程中的起吊、防脱、顶出和分样作业,保证样品质量,方便样品搬运,方便样品后续分析,大大提高了取样效率,保证了样品的完整性和保真性。
