“隐形轴阀式”厚壁取土器的开发与应用

本文介绍了全新专利产品"隐形轴阀式"厚壁取土器的结构、使用方法和在工程实践中的应用效果,证明隐形轴阀式取土器解决了目前厚壁取土器中所存在的问题,提高了厚壁取土器的取样质量和取样率,并简化了外业操作。

The following article introduces the structure,usage,and effection of in practice a 'Hidden piston-valve' type of Thick-Wall Tube Soil Sampler. Attests this newly designed sampler when comparing to the existing problems of Thick-wall samplers not only improves the quality of soil samples, but also increases the success rate of sample retrieval. And lastly it is convenient to use during outdoor operations.
