Description

Technical Field

[0001] The utility model relates to the technical field of road construction detection, in particular to a road construction quality detection device. Background Art

[0002] Road construction inspection is an important part of ensuring road quality. Road inspection items are inspected according to needs. Only by doing a good job of roadbed inspection can the quality of the entire project be guaranteed. Road inspection includes the inspection of roadbed thickness. After a section of road construction is completed, a cylinder is drilled at a random point on the section of road, and the thickness of the sample block is tested.

[0003] There is a document called "A Road Construction Detection Device" with patent announcement number CN117779571B. During the sampling process of drilling on the roadbed, if a hard object prevents the sampling tube from rotating and sampling and causes it to get stuck, the engaging wall drives the driving block to move up to disengage from the driving groove, and then the driving block enters the avoidance groove. The driving tube and the sampling tube rotate relative to each other, and under the drive of the anti-stuck component, the sampling tube is lifted up along the anti-stuck groove to avoid the hard object, and then the driving tube is extended to continue rotating for sampling. At the same time, the sampling tube drives the driving ring to lift up and squeeze the pre-compression spring to buffer the impact force of the hard object on the sampling tube when the sampling tube is stuck, thereby reducing the damage to the sampling tube caused by the hard object during drilling and sampling.

[0004] The device has a good sampling effect, but it is easy to generate a lot of smoke and dust during sampling, which seriously affects the environment and has poor reliability. Utility Model Content
