Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and more specifically, to a roadbed compaction testing device. Background Technology

[0002] In the field of road construction, subgrade compaction is a core indicator for evaluating construction quality, directly affecting the bearing capacity and service life of road structures. Subgrade compaction testing often employs traditional methods such as the ring cutter method or sand cone method for on-site sampling. However, traditional testing devices often require manual placement of the ring cutter vertically on the subgrade surface and application of fixed pressure, while another person repeatedly swings a heavy hammer for high-frequency hammering. This high-intensity physical labor not only poses safety hazards but also makes it difficult to maintain verticality and uniformity due to manual force application, easily leading to ring cutter skew or sample disturbance. Rapid on-site testing often involves adding alcohol to the sample and then burning it to quickly remove moisture. However, this method has certain safety risks, and moisture often remains inside the sample block, leading to errors in the test data. Utility Model Content
