本文介紹的連續采样装置,結构比較簡单,能用于流速仪纜道连續釆样。但是,它还处于試驗阶段,使用的水深、流速和泥沙量等条件尚有限制,已經积累的对比观测数据还不多,在結构上也还有某些不夠理想的地方?仪器在下沉过程中排气孔可能进水,进水时間不能随意控制,在較大的河流上,由于悬吊的东西較多,操作可能不十分灵便等等。这些均有待于研究改進。我們希望通过本文的发表,能促进对纜道采样方法的研究,經过不断改进,共同突破泥沙測驗上这一薄弱环节。
The continuous sampling device introduced in this paper has a simple structure and can be used for continuous sampling of the flowmeter cableway. However, it is still in the experimental stage. There are still limited conditions such as water depth, flow velocity, and sediment concentration. The comparative observational data that have been accumulated are not much yet. There are also some less than ideal areas in the structure. During the process of sinking, the vent hole may enter the water, and the water intake time may not be arbitrarily controlled. On the larger rivers, the operation may not be very flexible due to a large number of hanging objects. All of these are subject to research and improvement. We hope that through the publication of this paper, we can promote the research on sampling methods for cable channels, and through continuous improvement, we will jointly break through this weak link in sediment testing.
