Description

Technical Field

[0001] The utility model relates to the technical field of roadbed quality detection in highway construction, in particular to a sampling machine for measuring the compaction degree of highway lime soil base. Background Art

[0002] A layer of ash soil is laid on the roadbed during highway construction. At the same time, the ash soil must be compacted before the next process can be carried out. After the ash soil is compacted, its compaction degree needs to be measured. In the past, the sampling method for the compaction degree of highway ash soil base layer was to manually draw a circle on the ash soil layer and measure the compaction degree of the ash soil taken out from the circular hole. However, manual sampling is difficult and difficult to operate, and irregularly shaped sampling holes are prone to occur, resulting in poor sampling effects and inaccurate test data. There are currently some sampling equipment, which are generally bulky and difficult to carry. They cause great disturbance to the soil, have inaccurate positioning, and the walls of the sampling pits are not smooth, making sampling inconvenient. Moreover, these equipment cannot be applied to sampling on different ground surfaces and cannot determine the depth of sampling. Summary of the Invention
