Technical Field
[0001] The utility model relates to the technical field of concrete detection, in particular to a device for detecting the quality of engineering pavement concrete. Background Art
[0002] Before laying concrete on a highway pavement, the quality of the concrete after laying should be tested to prevent unqualified concrete from being used in roads, bridges and highway pavements. The use of unqualified concrete in water conservancy projects will cause safety hazards and accidents to the quality of the project structure. The concrete used in highway pavements is more susceptible to tilting forces, which mostly come from the rolling of vehicle wheels and the tilting pressure of braking inertia when the vehicle brakes. There is currently no test on the concrete's ability to withstand tilting forces.
