Roadbed compactness detection structure for road engineering detection

The utility model relates to the technical field of road engineering detection, in particular to a roadbed compactness detection structure for road engineering detection, which comprises a base, a detection mechanism and four adjusting mechanisms, each adjusting mechanism comprises a leveling instrument, an adjusting pipe, an adjusting threaded rod, an adjusting disc and a supporting rod, and four adjusting holes are formed in the base. The four adjusting pipes are fixed in the four adjusting holes respectively, the four adjusting threaded rods are fixedly connected with the adjusting disc and are in threaded connection with the adjusting pipes respectively, the four supporting rods slide in the four adjusting pipes respectively and are in rotating connection with the adjusting threaded rods respectively, and the four horizontal rulers are fixed to the top face of the base and are close to the four adjusting pipes respectively. And the detection mechanism is fixed on the top surface of the base. The roadbed c
