| titleOfInvention | Operation method of commercial concrete detection device |
| abstract | The invention relates to an operation method of a commercial concrete detection device, which comprises the following steps: 1) storing concrete; 2) sampling concrete; 3) detecting slump; 4) preparing a concrete sample; 5) demoulding the concrete sample; 6) and (5) testing the compressive strength of the concrete. The invention has the beneficial effects that: according to the invention, the storage bin and the discharge hopper are respectively sampled, so that the reliability of the sample is improved; meanwhile, an advanced sampling device is designed according to the requirement of sample preparation, so that the sampling efficiency can be improved, and the sampling operation error can be effectively reduced; the collapsed cylinder is firmly connected with the cylinder bottom transverse plate, and the position control precision of the collapsed cylinder can be improved; the collapse cylinder is jacked by the aid of the auxiliary jacking body, so that disturbance of lifting of the collapse cylinder on concrete can be reduced; the test cross rod is convenient to slide up and down, the levelness is easy to guarantee, and the accuracy of slump test can be improved. |
