AI Technical Summary

Technical Problem

In existing technologies, during the testing of highway subgrade compaction, soil debris falling from the pits affects the sand filling and sand removal operations of construction workers, resulting in poor testing results and low efficiency.

Method used

A detection device including a drilling rig and a filling assembly was designed. The filling assembly consists of a semi-circular shell, a rotating rod, a connecting belt, and a semi-circular bottom plate. After drilling, the filling assembly moves vertically in the pit, squeezing out soil debris and separating independent spaces to facilitate sand filling and sand removal operations.

Benefits of technology

It simplifies the operation steps for construction personnel, improves the accuracy and efficiency of testing, and ensures the effectiveness of highway subgrade compaction testing.
