Description

Technical Field

[0001] This utility model relates to a ring cutter for compacting and removing soil. Background Technology

[0002] The ring sampler method is a commonly used method for determining soil wet density. It is widely used in geotechnical engineering, agricultural research, and geological exploration. By using a ring sampler, soil density can be directly calculated, providing important data for engineering design, construction quality control, and soil improvement.

[0003] The removal of soil from the ring sampler is a crucial step in the ring sampler method for determining soil density. Its main purpose is to extract soil samples from the ring sampler for subsequent weighing and density calculation. After removing the soil from the ring sampler, the soil in the ring sampler is compacted, and the compacted soil is weighed together with the ring sampler. However, the weight of the ring sampler may vary over time, affecting the data results. Therefore, a device is needed that can completely remove the compacted soil from the ring sampler for high-precision testing. Summary of the Invention
