Problems solved by technology

In the route survey, considering the depth of subgrade influence, the convenience of construction and equipment handling, and economical factors, sampling is mainly carried out by manual Luoyang shovel or twist (spiral) drill, and only disturbed samples of grades III to IV can be taken for soil classification. , but the water content, density, consolidation and strength tests cannot be carried out
[0003] According to the "Code for Geological Survey of Highway Engineering" (JTJC20-2011), "Code for Geotechnical Engineering Survey" (revised in 2009) GB50021-2001, it is appropriate to use the rapid static continuous pressing method for soil samples, while the current Luoyang shovel, twist drill Neither can be realized. The ring knife can take the original sample on site, but it is only limited

Description

technical field [0001] The invention relates to the determination of a simple ring-cutter earth-taking device for a line, and belongs to the field of civil engineering. Background technique [0002] At present, the road survey mainly adopts drilling rigs to take samples, and the undisturbed samples and disturbed samples can be taken. In the route survey, considering the depth of subgrade influence, the convenience of construction and equipment handling, and economical factors, sampling is mainly carried out by manual Luoyang shovel or twist (spiral) drill, and only disturbed samples of grades III to IV can be taken for soil classification. , but the water content, density, consolidation and strength tests cannot be carried out. [0003] According to the "Code for Geological Survey of Highway Engineering" (JTJC20-2011), "Code for Geotechnical Engineering Survey" (revised in 2009) GB50021-2001, it is appropriate to use the rapid static continuous pressing method for soil samp...
