Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a drilling device for detecting the compactness of a roadbed. Background Art

[0002] The roadbed compaction test is the most common test during the roadbed construction process. At present, the commonly used roadbed compaction test method is the sand filling method, that is, digging holes on the roadbed and taking out the soil in the holes, and then filling the holes with standard sand. The compaction of the roadbed is calculated by testing the weight and moisture content of the excavated soil and the weight of the poured standard sand.

[0003] Before testing the compaction of the roadbed, it is necessary to dig holes at the testing points according to the design drawings and testing specifications. Since the testing process is mostly carried out in the field and energy cannot be obtained, testers currently often use chisels, hammers and other tools to dig holes in the roadbed. Due to manual operation and the use of relatively primitive tools for digging holes, on the one hand, the testing efficiency is relatively low and the test takes a long time. On the other hand, the dug holes are difficult to meet the testing standards and specifications, affecting the accuracy of the test data. Utility Model Content
