Description

Technical Field

[0001] This utility model relates to the technical field of highway testing devices, specifically a highway base compaction test device. Background Technology

[0002] As people's living standards improve and transportation becomes more advanced, highways are used more frequently. However, some highways are prone to damage after construction, mainly due to an unstable base layer, which affects people's quality of life. Therefore, it is necessary to test and compact the roadbed during the construction of some highways to ensure the quality of the highway.

[0003] Utility model patent CN219508530U discloses a test device for the compaction degree of highway base course, belonging to the technical field of highway testing devices. It addresses the problems in existing technologies where soil may contain stones that damage the ring cutter, and the unevenness of the test surface can lead to soil collapse during excavation, affecting test results and work efficiency. The device includes basic components, a compaction component, and a sampling component. The basic components include a testing box, with four fixedly connected wheels at the bottom corners, a controller fixedly connected to the front of the bottom inner wall of the testing box, a stone detector fixedly connected to the rear of the bottom of the testing box, and exhaust fan boxes fixedly connected to the left and right ends of the testing box, with dust collection pipes fixedly connected to the bottom of each exhaust fan box. In this invention, the bottom edge of the flattening frame contacts the surface of the lower force-bearing slide plate, which then compresses the slide plate downwards against the inner wall of the detection chamber.
